E Class vs 5 Series: Key Differences for Irish Buyers
The Mercedes E-Class and BMW 5 Series go head-to-head in Ireland’s executive saloon segment. Pricing and model availability look a bit different across the Republic and Northern Ireland.
Executive Saloon Segment in Ireland
This executive saloon class stays fiercely competitive between these German heavyweights. Irish buyers keep the BMW 5 Series and Mercedes E-Class near the top of the sales charts for both brands.
Irish drivers still favour diesel engines, especially for long distances. Both BMW and Mercedes offer a solid range of diesels, with the 520d and E 220 d leading the pack. Hybrid options are slowly catching on, mainly around Dublin and Cork where charging points are easier to find.
Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives, points out, “Irish buyers typically prioritise long-distance comfort and fuel economy over outright performance, which explains why both manufacturers focus heavily on their diesel offerings here.”
Fleet buyers really shape this segment in Ireland. Company car tax perks and strong resale values make both models a smart choice for business folks. The executive saloon vibe appeals to professionals who want prestige but don’t want the costs of even bigger luxury cars.
Model Range and Availability
BMW brings a wide engine lineup for the 5 Series in Ireland:
- 520i (2.0-litre petrol, from €51,000)
- 520d (2.0-litre diesel, from €52,000)
- 530e (plug-in hybrid, from €59,739)
- 530d (3.0-litre diesel)
- 540i xDrive (3.0-litre petrol, all-wheel drive)
Mercedes matches with:
- E 200 (2.0-litre petrol)
- E 220 d (2.0-litre diesel, from €52,500)
- E 300 e (petrol plug-in hybrid, from €58,325)
- E 300 de (diesel plug-in hybrid, from €60,220)
- E 400 d (3.0-litre diesel)
Northern Ireland buyers get the same models, but pricing is different. UK-spec cars often come with a bit more standard kit compared to what’s offered in the Republic.
Pricing Comparison in the Irish Market
Prices really do vary between the Republic and Northern Ireland. In the Republic, prices include VRT, while in the North, you pay UK prices without that extra tax.
Republic of Ireland Pricing:
- BMW 520d M Sport: about €58,000
- Mercedes E 220 d AMG Line: about €59,000
- Both include VRT and dealer delivery
Northern Ireland Pricing:
- BMW 520d M Sport: about £46,000
- Mercedes E 220 d AMG Line: about £47,500
- Prices exclude delivery but include the first registration fee
The BMW tends to score higher in customer satisfaction surveys. This helps the 5 Series hold its value a bit better than the E-Class in Ireland.
Motor tax rates line up for cars with similar CO2 emissions. Both brands now offer low-emission models that qualify for reduced annual tax in the Republic.
Performance Comparison: Engine Options and Driving Dynamics

The BMW 5 Series and Mercedes E-Class take different tacks on performance. The BMW leans into driving fun, while the Mercedes doubles down on comfort. The 5 Series feels sharper and more agile, but the E-Class rides smoother and softer.
Power and Acceleration
BMW gives Irish buyers a broader engine choice. The entry 520i makes 184hp from its 2.0-litre petrol, though honestly, it feels a bit underpowered next to the punchy 252hp 530i.
For diesel fans, the 530d’s 3.0-litre engine offers strong performance. It’ll hit 0-62mph in 5.7 seconds and still claim up to 60mpg.
Mercedes seems to prefer diesel for most models. The E220d’s 2.0-litre diesel actually outpaces BMW’s equivalent and runs quieter. It does 0-62mph in 7.3 seconds and offers up to 72mpg.
Hybrid Options:
- BMW 530e: 292hp combined, 46g/km CO₂
- Mercedes E350e: 282hp combined, 42g/km CO₂, 40-mile electric range
Ciaran Connolly says, “The 530d remains the sweet spot for Irish buyers, offering genuine performance with lower motor tax bands compared to petrol variants.”
Handling Characteristics
The BMW 5 Series keeps its reputation as the driver’s car. When you’re behind the wheel, it somehow feels smaller and more nimble than it looks. The steering is sharp, and the chassis stays composed through bends.
BMW’s rear-wheel-drive setup makes a real difference for driving enthusiasts. If you add the optional adaptive dampers (£1,000), you get a ride that’s almost as comfy as the Mercedes, but without losing that sporty edge.
Mercedes, on the other hand, puts comfort first. The big dashboard and soft suspension create a relaxed vibe, but you’ll notice more body roll if you push it hard.
Add the optional air suspension (£1,500), and the E-Class just floats over rough roads. It’s a proper cruiser, perfect for those long motorway runs between Dublin and Belfast.
Transmission and Drivetrain Advantages
BMW equips every 5 Series with an eight-speed automatic. This gearbox feels quick and responsive, which suits the car’s sporty character. Shifts come faster than in the Mercedes.
BMW’s xDrive four-wheel drive is standard on all diesels and some of the more powerful petrols. That’s a real bonus on Irish roads in winter.
Mercedes uses a nine-speed automatic throughout the E-Class range. It’s smooth and quiet, but it’s more about comfort than quick shifts. The extra gears help with motorway fuel economy.
Mercedes’ 4MATIC all-wheel drive is available on most models, except the entry-level ones. It works fine, but it doesn’t have the same rear-wheel feel as BMW’s xDrive.
Transmission Comparison:
| Feature | BMW 5 Series | Mercedes E-Class |
|---|---|---|
| Gearbox | 8-speed auto | 9-speed auto |
| Shift Speed | Quick, responsive | Smooth, refined |
| AWD Availability | All diesels, higher petrols | Most models |
Comfort and Interior Space: Passenger Experience
Both the BMW 5 Series and Mercedes E-Class focus on driver comfort with cleverly designed cabins. Each brand takes a different approach to seating and layout, though. Real-world space measurements show that both cars have some surprising limitations, despite their size.
Seating Comfort
BMW’s 5 Series gives you excellent front seats with strong lateral support—great for cornering. You can adjust the seats in loads of ways, so finding a comfortable driving position is easy.
Most trims include electric seat adjustment, and you get memory functions on higher-spec models. The materials feel top-notch, especially in M Sport versions with perforated leather.
Mercedes goes softer with the E-Class seats. They’re all about long-distance comfort, not sporty support, so they’re perfect for motorway cruising.
Both brands offer ventilated seats as an option. That’s a lifesaver in summer or if you drive a lot.
Ciaran Connolly sums it up: “The seating position in both cars reflects their target audience – the BMW appeals to drivers who enjoy spirited driving, whilst the Mercedes focuses on executive comfort.”
Rear Cabin Room and Practicality
Space in the back is a letdown for both cars, considering their length. Tall passengers will find rear legroom pretty tight.
The BMW 5 Series struggles most here. If two six-footers sit one behind the other, knees will definitely touch the front seats.
The E-Class does a bit better for rear passengers, but it’s not a huge improvement. The rear bench fits three, though the middle spot is best for short hops.
Boot space isn’t equal either. The BMW 530e plug-in hybrid keeps its full luggage capacity. The Mercedes E300e hybrid loses 170 litres compared to its diesel sibling, which can be a pain for families.
Both cars give you split-folding rear seats for longer items. The boot loading height is reasonable, making shopping trips manageable.
Driving Position Assessment
BMW nails the driving position in the 5 Series. The seat sits lower than in the Mercedes, which gives a sportier vibe that many drivers love.
Dashboard controls are within easy reach, but the latest iDrive system can get annoying—most physical buttons are gone, so you’re stuck using the touchscreen for basic stuff.
Mercedes sticks to a more classic setup. The higher seat gives you a great view forward, which helps in busy city traffic.
Both cars have steering wheels that adjust a lot. Paddle shifters come standard, so you can take manual control of the auto boxes if you want.
Visibility up front is excellent thanks to upright windscreens. Thick C-pillars make rear visibility a bit tricky, so parking sensors are a must.
Technology and Infotainment Features
Both cars come loaded with digital tech. BMW’s new 5 Series features a 12.3-inch display, while Mercedes offers its slick MBUX system. The driving assistance features aren’t quite the same between these German rivals.
Digital Displays and Connectivity
The facelifted BMW 5 Series now gets a 12.3-inch infotainment screen as standard. That’s a big step up from older models.
BMW gives you a dual-screen setup—digital instruments and a central display. Wireless Apple CarPlay and Android Auto come standard in both Irish and Northern Irish markets.
Mercedes fights back with its HYPERSCREEN on higher trims—a curved glass panel that stretches across the dashboard. The base E-Class still has separate digital screens for the driver and infotainment.
Connectivity features include:
- 5G capability (both brands)
- Over-the-air software updates
- Remote control via smartphone apps
- Built-in navigation with live traffic
Ciaran Connolly adds, “Digital displays have become the primary selling point for executive cars in Ireland, with buyers expecting tablet-like responsiveness and smartphone integration.”
Infotainment Systems: iDrive vs MBUX
BMW’s iDrive 8 system gives you both a rotary controller and touchscreen. The interface stays pretty straightforward, with menus that actually make sense. I notice the system reacts quickly—no frustrating lag.
The BMW 5 Series keeps its infotainment easier to use than Mercedes’ setup. You still get physical buttons to back up the touchscreen.
Mercedes’ MBUX system leans hard into voice commands and touch. Just say “Hey Mercedes” and the natural language processing kicks in. Over time, it learns what you like.
Here’s what really sets them apart:
- BMW still gives you the physical iDrive controller
- Mercedes adds more gesture controls
- Both let you set up multiple user profiles
- Navigation includes charging points
Driver Assistance Technologies
Both brands pack in Level 2 autonomous driving features. BMW’s Driving Assistant Professional brings adaptive cruise control with stop-and-go.
Mercedes calls its system Drive Pilot, which lets you drive hands-free in certain conditions. It works on motorways up to 60km/h, mainly during traffic jams.
Standard safety features:
- Automatic emergency braking
- Blind spot monitoring
- Lane keeping assist
- Traffic sign recognition
- Parking sensors and cameras
Mercedes’ system tends to intervene more, while BMW leaves you with a bit more control. Both cars earned five-star Euro NCAP ratings with these tech features standard in Ireland and Northern Ireland.
Plug-in Hybrids and Electrified Driving
The BMW 5 Series and Mercedes E-Class both offer plug-in hybrid systems with about 50km of electric range. Mercedes offers diesel PHEV options, while BMW focuses on petrol-electric setups.
Plug-in Hybrid Availability
In Ireland, you’ll find two plug-in hybrid BMW 5 Series models. The 530e comes with a 2.0-litre turbo petrol plus electric motor. BMW also builds a more powerful 545e with a six-cylinder petrol.
Both qualify for the €2,500 SEAI grant. The 530e starts at €59,739 after grants, but M Sport Pro specs can push prices over €80,000.
Mercedes takes a different route for the E-Class PHEV. You get both petrol and diesel plug-in hybrids. The E 300 e uses a petrol-electric setup, while the E 300 de combines diesel with electric assist.
The E 300 de starts at €60,220 after grants in AMG Line Exterior trim. This diesel hybrid weighs about 150kg more than the BMW 530e, which impacts performance and efficiency.
“The diesel PHEV option in the E-Class makes sense for long motorway runs, but BMW’s petrol hybrid feels less compromised for mixed driving,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Hybrid System Performance
The BMW 530e puts out 292hp and 420Nm of torque, doing 0-100km/h in 5.9 seconds. The petrol-electric combo gives smooth power, and BMW’s ‘Xtraboost’ bumps performance in Sport mode.
BMW pairs this with an eight-speed automatic that offers several driving modes. The petrol engine stays quieter than Mercedes’ diesel when you run out of battery.
Mercedes’ E 300 de makes more power at 306hp and a hefty 700Nm of torque. Still, it only matches the BMW’s 0-100km/h time, mostly due to its extra weight.
The diesel engine pulls hard in the mid-range but isn’t as refined as BMW’s petrol. Mercedes uses a nine-speed automatic that shifts smoothly, but the diesel gets noisy under load.
Both hybrids switch between electric and petrol or diesel without fuss. The BMW feels sharper and more dynamic, while Mercedes goes for comfort and long-haul ease.
Electric Range and Usability
Both cars manage around 50km of electric range on a full charge. The BMW 530e claims 51km WLTP from its 12kWh battery.
BMW’s system runs more efficiently at 13.8-14.9kWh/100km, compared to the Mercedes’ 15.5kWh/100km. The 5 Series keeps a flat boot floor with room for your charging cables.
Mercedes gives the E 300 de a bigger 13.5kWh battery, but it’s heavier. The boot has a weird step that makes it less usable than the BMW’s.
Real-world fuel economy depends a lot on how often you charge. Mercedes does better on the motorway with its diesel engine. BMW can match that if you’re not relying on electric power.
You really need to stick to a charging routine to get anywhere close to the official fuel numbers. Irish buyers don’t have zero-emissions zones yet, so electric-only driving in cities isn’t much of a thing.
Design and Aesthetics: Exterior Comparison
The Mercedes E-Class and BMW 5 Series couldn’t look more different. The E-Class leans into refined elegance, while the 5 Series feels built for drivers who want a sportier vibe.
E Class: Elegance and Prestige
Mercedes shapes the E-Class with luxury in mind, not aggression. Up front, you get that iconic three-pointed star in a chrome grille—nobody’s mistaking it for anything else.
The headlights have a notched profile and LED running lights. You spot the E-Class right away on Irish roads.
Down the sides, the E-Class keeps smooth body lines instead of sharp creases. That gives it a timeless look that plenty of executives love.
The rear has a full-width light bar, borrowing from Mercedes’ EQ electric cars. Chunky LED taillights include 3D star elements—maybe a bit flashy for some.
Chrome details run along the trim, adding to the luxury feel. Even the window surrounds and door handles get some extra attention.
5 Series: Sporty Appeal
BMW’s 5 Series goes for a more dynamic design. The kidney grilles stay slim, dodging the oversized look on other BMWs.
The front bumper has bigger air intakes and more aggressive lines. It looks sportier than the Mercedes, but still fits the executive sedan mold.
Sharp creases run down the sides, creating interesting shadows. The classic Hofmeister kink sits at the rear window, though BMW now stamps a ‘5’ badge nearby—some love it, some don’t.
At the back, you’ll see narrow, elongated taillights inspired by the 7 Series. The whole car looks like it’s in motion, even parked.
BMW took a fresh approach here, not just tweaking the old design. I suspect it’ll age better than the E-Class, which sticks closer to tradition.
Trim Options: AMG and M Sport
AMG Line gives the E-Class a meaner look. The front bumper gets bigger air intakes and a chunkier splitter.
Side skirts and rear diffusers add some drama, and 19-inch wheels help the stance. Chrome gets swapped for gloss black in places.
M Sport makes the 5 Series even bolder. The front bumper gets more sculpted, with extra air intakes and sharper lines.
“Irish buyers really go for M Sport on the 5 Series—it looks the part, but you don’t get the running costs of a full M car,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
| Feature | AMG Line E-Class | M Sport 5 Series |
|---|---|---|
| Wheel sizes | 19-20 inch options | 19-20 inch options |
| Body kit | Subtle enhancement | More aggressive styling |
| Interior changes | AMG steering wheel | M steering wheel with red marker |
| Trim accents | Gloss black available | Red and blue translucent details |
Both packages tweak the interiors too, so the sporty theme runs all the way through.
Running Costs and Fuel Consumption in Ireland

Both the BMW 5 Series and Mercedes E-Class are pricey to run, but BMW usually comes out a bit cheaper for servicing and insurance. Real-world fuel economy can be a lot worse than the official numbers, especially with Ireland’s mix of city traffic and motorways.
Official Fuel Economy Figures
BMW 5 Series diesels claim 4.1-5.2L/100km in WLTP tests. Mercedes E-Class diesels are close, at 4.3-5.4L/100km depending on engine.
Petrol models drink more. The BMW 520i does 6.8L/100km, and the Mercedes E200 manages 6.9L/100km.
Plug-in hybrids look great on paper:
- BMW 530e: 1.7L/100km combined
- Mercedes E300e: 1.6L/100km combined
Those numbers only work if you charge regularly and mix up your driving. BMW 5 Series plug-in hybrids are popular with business drivers because of the low benefit-in-kind tax.
Real-World Consumption and Efficiency
In my experience, real-world numbers are a lot higher than the official ones. The Mercedes E-Class averages 43.5mpg here—that’s about 6.5L/100km.
BMW 5 Series diesels usually give 6.0-7.5L/100km in Irish driving. That’s with Dublin traffic and motorway runs to Cork or Belfast.
Petrol engines use 8.0-10.5L/100km in real life. With Irish fuel at €1.45-1.55 per litre, costs add up fast.
“Irish driving, with all the stop-start in Dublin and Cork, pushes real-world consumption 15-20% above official figures for these executive saloons,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Irish Road Tax and Insurance
Motor tax varies a lot by model and CO2. The most efficient diesels cost €200 a year, but higher-emission petrols can hit €750-1,200.
Annual motor tax bands:
- BMW 520d: €200-280
- Mercedes E220d: €200-280
- BMW 530i: €570-750
- Mercedes E300: €750-1,200
BMW usually wins on insurance. Group ratings are 2-3 points lower than Mercedes, saving most drivers €150-300 a year.
Both brands want expensive servicing at main dealers. BMW charges €350-450 for a basic service, Mercedes asks €380-480. Go to an independent and you might save 30-40%, but you could risk your warranty.
Ownership Experience: Practicality, Reliability, and Resale
When it comes to daily usability, long-term dependability, and depreciation, these German executive saloons really do feel quite different to own. Irish drivers have their own set of challenges with both models, especially around maintenance costs and resale values.
Practical Features for Daily Use
Both the 5 Series and E-Class offer strong practicality for Irish families and business folks. The E-Class edges ahead with 908mm of rear legroom, a bit more than the 5 Series’ 851mm.
Boot space? Mercedes wins again, with 540 litres compared to the BMW’s 530 litres. The E-Class also makes loading easier thanks to a more accessible boot opening height.
Interior Storage Comparison:
- Door pockets: E-Class (1.3L) vs 5 Series (1.1L)
- Centre console: Both cars support wireless charging
- Cup holders: E-Class places them better
Tech-wise, BMW’s iDrive system just feels easier if you’re into gadgets. Mercedes’ MBUX takes longer to get used to, but its voice commands are honestly top-notch.
Rear seat comfort is a big deal for families. The E-Class gives you better cushioning and support, especially on longer trips. Both cars can fit three adults for motorway journeys across Ireland without much fuss.
Fuel tank size is another difference. The E-Class holds 66 litres, while the 5 Series takes 68 litres. That means the BMW can squeeze out about 50km more on the motorway.
Long-Term Reliability
Mercedes E-Class reliability ratings usually beat the BMW 5 Series in most major studies. Consumer Reports puts the E-Class ahead, with fewer issues and better durability over time.
The E-Class engines handle high mileage with fewer headaches. BMW engines, especially after 100,000km, can get a bit leaky or develop cooling system problems.
Common BMW 5 Series Issues:
- Electrical gremlins in infotainment
- Brake pads that wear out early
- Air suspension failures (if fitted)
- Oil leaks
Mercedes E-Class Problems:
- Some timing chain issues
- Transmission control module faults
- Minor electrical quirks
Repair costs can really add up. RepairPal says the 5 Series averages €920 a year, while the E-Class comes in at €736. Irish mechanics also seem to find Mercedes parts more available.
“The Mercedes E-Class consistently shows 15-20% lower maintenance costs over five years of ownership, particularly important given Ireland’s high labour rates,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Warranty coverage looks pretty similar, but Mercedes dealers in Ireland often deliver a better service experience, according to customer surveys.
Resale Values in Ireland
Resale values in Ireland tend to favour the Mercedes E-Class. After three years, the E-Class keeps about 52% of its value, while the 5 Series holds onto 47%.
Diesel models do best here. The E220d usually outpaces the 520d by €2,000-€3,000 after four years. Petrol versions don’t show as big a gap, but Mercedes still leads.
Depreciation Factors:
- Popularity with Irish fleet buyers
- Reputation for reliability
- Service network reach
- Parts and repair costs
Irish executive car buyers like the classic Mercedes luxury vibe. That preference really boosts resale values across all trims.
In Northern Ireland, things shift a bit. BMWs hold their value slightly better due to different buyer tastes and fleet deals. The difference shrinks to about 2-3%.
Colour matters, too. Silver and black E-Class models fetch more, while BMW’s Alpine White is the most wanted. Odd colours like red or yellow just don’t hold up as well.
Mileage tells a story. High-mileage E-Class cars (over 150,000km) keep their value better than BMWs, probably because people see them as more durable.
Interior Ambience: Materials and Lighting
Step inside, and you’ll notice the cabins feel very different. The E-Class sets the bar for material quality and ambient lighting, while the 5 Series leans into a more driver-centric setup.
Material Quality and Finish
The E-Class stands out for its interior materials, really raising the bar for luxury. Mercedes uses real leather with excellent stitching and softer plastics all over the dash.
BMW’s 5 Series uses good materials, but you can spot some cost-saving here and there. The dash mixes hard and soft plastics, but the driver-focused layout is still appealing.
Key Material Differences:
| Feature | Mercedes E-Class | BMW 5 Series |
|---|---|---|
| Dashboard finish | Soft-touch plastics | Mixed hard/soft plastics |
| Seat materials | Premium leather standard | Synthetic leather base trim |
| Trim options | Real wood, metal inlays | Synthetic alternatives available |
The E-Class cabin feels plush and upscale. Even the door cards use the same premium materials and feel solid.
“Material quality directly impacts ownership satisfaction and resale values in Ireland’s executive car market,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Ambient Lighting Features
Mercedes really shines with its ambient lighting. The Active Ambient Lighting wraps around from the windscreen, through the doors, and even into the dash.
The E-Class ambient lighting just looks stunning and lets you pick from 64 colours. The lights flow into the air vents, door handles, and all over the dash.
BMW’s lighting system is more about function than pure mood. The colours change when you get calls or warnings, so it’s handy for getting your attention.
Ambient Lighting Comparison:
- Mercedes E-Class: 64 colours, panoramic integration, mood-based settings
- BMW 5 Series: 11 colours, functional alerts, customisable zones
BMW highlights important controls and gives visual feedback for car functions. It’s practical, but not quite as atmospheric.
You can personalise both systems through the infotainment. Mercedes goes all-in on luxury, while BMW keeps things focused on the driver.
Driving Impressions: Comfort Versus Engagement
The E-Class puts comfort first with a softer suspension and excellent noise isolation. The 5 Series, meanwhile, goes for sharper handling and more direct feedback—great for those who love to drive. Each car has a strong personality, so your choice really depends on what you want.
Ride Quality Assessment
Mercedes tunes the E-Class suspension for comfort. The air suspension soaks up bumps and potholes, which suits Ireland’s rougher roads.
I noticed the E-Class softens harsh surfaces for a cushier ride. It smooths out potholes and uneven tarmac, which you’ll find plenty of on Irish backroads.
BMW’s Different Philosophy:
- Suspension feels firmer for sharper handling
- Chassis gives you more road feedback
- Sport modes make a noticeable difference
The BMW 5 Series feels firmer, prioritising handling over comfort. Its setup gives you better grip in corners, but you’ll feel more of the bumps.
“Irish roads particularly test suspension components, with the E-Class proving more forgiving on damaged surfaces whilst the 5 Series rewards smooth motorway driving,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Noise and Refinement Levels
Mercedes puts a lot into making the E-Class quiet. At motorway speeds, the cabin stays calm—wind and road noise barely make it inside.
Engine noise is a different story. I found the BMW is actually quieter and sounds more refined than the Mercedes when accelerating.
Refinement Comparison:
- E-Class: Best for wind and road noise isolation
- 5 Series: Quieter engines and smoother power delivery
- Both models use active noise cancellation
The 5 Series engines, especially the petrols, feel smoother and quieter. Mercedes diesels, on the other hand, can sound a bit rough when you push them.
Advanced Safety and Assistance Systems

Both the E-Class and 5 Series now pack mandatory advanced safety systems thanks to new EU rules from July 2024. These include drowsiness detection, blind spot monitoring, and intelligent speed assistance as standard.
Active Safety Technologies
The EU safety regulation now requires specific ADAS features as standard. Every new E-Class and 5 Series in Ireland now includes drowsiness detection, advanced emergency braking, and intelligent speed assistance.
Mercedes installs their blind-spot and lane-keep systems as standard. The system keeps an eye on traffic and warns you if a lane change isn’t safe.
BMW focuses on iDrive with improved voice and steering wheel controls. The 5 Series also includes lane departure warnings and emergency braking, but you have to turn some of these off every time you start the car.
Both cars support alcohol interlock installation, handy for fleet buyers who need breathalysers.
“The mandatory safety systems add approximately €800-1,200 to the base cost of both vehicles, but Irish drivers benefit from potentially lower insurance premiums,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Passive Safety Features
Neither car has been tested by Euro NCAP under the latest rules yet, but both brands expect five-star ratings. Euro NCAP Safety Assist scores will show how well these systems work in real life.
The E-Class comes with heated door panels and plenty of airbags in every trim. Mercedes uses seats from the C-Class, and higher trims get massage functions.
BMW’s 5 Series offers a full airbag system and a reinforced passenger cell. Heated and climate seats come standard, but you’ll only get massage seats on higher trims.
Both cars meet current European rules for pedestrian and occupant safety. Their bigger size over older models adds more crumple zones for protection.
Irish NCT requirements match these EU safety standards, so both cars should pass inspection without any issues during their lifespan.
Choosing Between E Class and 5 Series in Ireland
The BMW 5 Series and Mercedes E-Class both go after Irish business professionals and families. Pricing and equipment levels feel pretty similar.
BMW usually gives you better driving dynamics. Mercedes leans more into luxury and long-distance comfort.
Which Executive Saloon Suits Irish Drivers?
Irish motorists have a few unique things to think about when picking between these German saloons.
The BMW 5 Series draws in drivers who love actually driving. Its chassis feels lively on Ireland’s twistier roads, and the eight-speed auto shifts with real precision.
The Mercedes E-Class goes after buyers who want comfort above all. You’ll notice the extra sound insulation and softer suspension, especially on long trips between cities.
Its nine-speed auto shifts smoothly, but not especially quickly.
“Irish business drivers typically cover 25,000-30,000 miles annually, making the E-Class’s refinement advantage particularly relevant for motorway comfort,” says Ciaran Connolly, Lead Reviewer at Amazing Cars and Drives.
Both cars offer plenty of engine choices, from efficient diesels to plug-in hybrids.
The 5 Series 530d pulls hard and claims up to 60mpg. Mercedes fights back with the E 300 de diesel-electric hybrid, but that one eats into boot space and adds some complexity.
Irish buyers should weigh up their own driving style and what they want most.
Pick the BMW if you crave sharp handling. Go for the Mercedes if you care more about passenger comfort and a smoother ride.

What are the new features expected in the 2025 E-Class model?
The 2025 E-Class will get a faster MBUX system. Mercedes plans to roll out new driver assistance features too.
You’ll see updated exterior styling and new LED headlights. The cabin picks up new trim and ambient lighting.
A plug-in hybrid with over 60 miles of electric range should hit Irish showrooms by Q2 2025.

Can you contrast the estate versions of the Volvo V90 and the Mercedes E-Class?
The Mercedes E-Class Estate packs in more boot space than the Volvo V90. You get 640 litres with the seats up in the E-Class.
The Volvo V90 offers 560 litres of cargo space. Rear passenger comfort and space feel about the same in both.
The V90 starts cheaper, at around €52,000 in Ireland. The E-Class Estate starts closer to €58,000.
Mercedes gives you more engine options, including diesel and petrol. Volvo mostly sticks with mild-hybrid petrols.
Insurance costs usually favour the Volvo by a group or two. The V90 also tends to keep its value better after three years in Ireland.
What are the differences between the Audi A6 E-Tron Avant and the BMW i5 Touring?
The Audi A6 E-Tron Avant claims up to 476 miles of WLTP range. BMW’s i5 Touring manages 357-390 miles, depending on spec.
Both cars come with dual-motor all-wheel drive as standard. The Audi puts out 382bhp in base form.
BMW’s i5 Touring ranges from 335bhp to 590bhp. The M60 is the quickest of the bunch.
Charging speeds set them apart. The A6 E-Tron can fast charge at 270kW DC.
BMW caps the i5 Touring at 195kW for fast charging. Irish buyers will probably wait longer for the Audi to arrive.
How do the BMW 520d and the Mercedes E220d fare against each other in terms of efficiency and power?
The BMW 520d puts out 190bhp and manages some seriously good fuel economy. In everyday driving, you’ll probably see 45-50mpg.
Mercedes E220d cranks out a bit more at 195bhp, plus it’s got slightly higher torque. You can expect around 42-47mpg if you drive it in similar conditions.
Both cars use mild-hybrid tech to help with efficiency. BMW’s system, though, seems to make the start-stop feel smoother.
Service intervals line up at 18,000 miles or every 24 months. In Ireland, BMW dealers usually ask for €50-100 less per service, which is a nice little bonus.
Road tax comes in at €280 per year for both if you’re in Ireland. Over in Northern Ireland, you’ll pay £180 VED for either one.
