Mercedes-Benz Eqb250 vs McLaren 540C

What's the difference?

The EQB is a likeable yet complicated machine.

On one hand, the high pricing is a real hurdle, even in the base 250, while the 350 4Matic costing the wrong side of $110K driveaway can’t even be had with seven seats. What is the point of it? 

On the other, though, the EQB is roomier than its appearance suggests, way lovelier inside than anticipated, and – especially after allowed to really be driven hard and fast – a whole lot more Mercedes-Benz in the way the 350 4Matic moves, steers, grips, rides and stops.

As a result, we’d skip the capable but bland 250 and try to haggle hard on the price of the altogether too-expensive yet compelling 350 4Matic instead. It’s the EQB to be in.

The 540C is desirable on so many levels. Its dynamic ability, blistering performance, and stunning design make the cost of entry a value-for-money ticket. And the refreshing thing is, choosing a McLaren, with its focus on function and pure engineering, sidesteps the wankery that so often goes with ownership of an 'established' exotic brand. We absolutely love it.

The EQB does not employ a dedicated EV architecture – sometimes referred to as a ‘skateboard’ platform – like the Tesla Model Y, or for that matter the brilliant Hyundai Ioniq 5, Kia EV6 and Genesis GV60 at around the Benz’s price points.

By this, we mean that it was originally designed as an internal combustion engine (ICE) vehicle. In this case, what lies beneath is the MFA2 platform, first seen in the redesigned A-Class hatch back in 2018, and applied to all transverse-engined Mercedes models since.

The upshot here is that there are some compromises as a result compared to the aforementioned EV-only alternatives, namely concerning packaging as well as weight distribution in some cases.   

Like we said earlier, the EQB’s design is eye-catching and quite handsome. It is clear that the success of the GLB that spawned it is partly attributed to the chunky, almost function-over-form tall-boy utilitarian styling. That ‘W’ shaped window-line kink is an interesting visual feature too.

The changes from GLB to EQB do give the EV definite points of difference, from the front-end’s black flat panel and fibre optic light that connects the (blue-highlight) headlights, to the curved strip LED tail-lights and bumper-sited numberplate mount.

We reckon the 20-inch AMG turbine wheels really do enhance the EQB aesthetically as well, but of course they’re an option on the 250. Though probably not in Gold Rose.

In 2010 the recent rise (and rise) of McLaren Automotive really began, when its design director, the hugely respected Frank Stephenson, started to send things in a compelling direction.

He says McLarens are 'designed by air' and that intricately sculpted, wind-tunnel-driven approach to supercar beauty is clear in the 540C's shape.

It's aimed at so-called everyday supercars like the Audi R8, and Porsche 911 Turbo, yet it incorporates all the subtle aero tricks that define the brand's dynamic personality.

A serious front spoiler and a mix of large intakes low in the nose create a delicate balance between downforce and corridors for cooling air.

The dihedral design doors swinging up to their fully open position is a camera phone attracting, jaw dropping, traffic-stopper.

Broad strakes down the side, standing proud of the main bodywork, are reminiscent of a formula one car's turbulence reducing barge boards, and giant intake ducts channel air through to the radiators in the cleanest, most efficient way possible.

And the look is suitably spectacular. You could hang the dramatically carved doors in a contemporary art museum.

Barely noticeable flying buttresses extending from the rear of the main roofline make a big contribution to downforce, cooling and stability with a minimal drag penalty.

There's a delicate lip spoiler on the trailing edge of the main deck, and a giant multi-channel diffuser proves air flow under the car is just as carefully managed as that going over it.

But the 540C doesn't lack traditional supercar drama. The dihedral design doors swinging up to their fully open position is a camera phone attracting, jaw dropping, traffic-stopper.

The interior is simple, striking and single-mindedly driver-focused. The chunky wheel is completely unadorned, the digital instruments are crystal clear, and the seats are the perfect combination of support and comfort.

The vertical 7.0-inch 'IRIS' touchscreen is cool to the point of minimalism, managing everything from audio and nav, to media streaming and air-con, with low-key efficiency.

As with the popular GLB that spawned it, there’s more to the EQB than meets the eye.

Photos mask the German electric vehicle’s considerable length and height as well as the substantial space offered inside, giving the Mercedes a handy advantage compared to premium alternatives like the Volvo XC40 Recharge, the Genesis GV60 and BMW’s recently announced (and quite handsome in the flesh) iX1 due early next year.

In fact, the EQB’s lengthy 2829mm wheelbase accommodates the batteries as well as impressive cabin packaging flexibility. Its 4684mm body is actually 26mm longer and 37mm higher than the larger, current-shape (X253) GLC, though width is identical to the EQA, making this a long, tall but quite narrow SUV proportionally speaking.

That expansive feeling is boosted by deep side windows offering reassuring all-round vision, boosted by an excellent driving position. All launch vehicles had the AMG sports seats (optional on the EQB 250, so we can’t speak for the base model), but as tested, they provided hours and hours of comfort and support. Loads of adjustability also help.

The EQB’s dash design is attractive and contemporary, though it can also seem daunting at first, requiring time to learn and understand where all the switchgear and controls are. The ‘Hey, Mercedes’ voice command mostly works well, too, and can provide additional tuition. The multimedia screen can be swiped like a tablet/iPad, or controlled via a fiddly touchpad on one of the steering wheel spokes.

Once mastered, the layout is logical and operation clear… with the exception of the drive selector on the right-hand side, which can be confused for an indicator and so knocked out of ‘gear’ and into Neutral on a regular basis. This has been a two-decade-long criticism of Mercedes models.

As with most MFA2 vehicles, the interior design and quality are a big step forward compared to earlier efforts. Multi-configurable digital instrumentation (including an elegant uncluttered mode), gorgeous turbine-look vents, a row of classy toggle switches for the main buttons and a great steering wheel are highlights to behold. Storage seems endless, reinforcing the practical nature of this cabin.

Speaking of which, stepping into the rear (second row) seats further underlines the EQB’s spaciousness. Entry/egress is easy due to wide-opening doors, taller folk should find ample room for knees, legs and (especially) heads, and the (slightly reclinable) backrest does its job. Comfy if firm cushions also slide forward (by up to 140mm) when required.

That’s to aid third-row access (where applicable). To that end, the second-row seats also tilt to allow people to squeeze past. Note, though that this is really a kids-only area, rated for occupants no taller than 1.65 metres. Surprisingly cosy, both chairs are OK for short trips, but longer ones would be a stretch too far except for the smallest passengers. 

Keep in mind that all outboard middle and rear seats where fitted have ISOFIX latches for child seats.

Luggage space is another EQB bonus, offering 130 litres with all seven seats up, or 495L with the third-row folded. Drop the middle row and there’s 1710L (or 1620L in seven-seater versions). These figures are between 20L to 60L down compared to the GLB.

Note, too, there is no spare wheel fitted. Just a tyre-repair kit.

There are some cursory concessions to practicality… like a glovebox, a single cupholder under the dash at the leading edge of the centre console, a small bin between the seats, housing multiple USB outlets, and other storage options here and there.

The latter includes a shelf at the top of the bulkhead behind the seats, marked with a specific label saying (words to the effect of) 'don't put stuff here', but that's more about objects flying forward in a high-G deceleration, which in this car is more likely to be the result of hitting the brakes, rather than a crash.

But the 'big' surprise is the 144-litre boot in the nose, complete with light and 12 volt power outlet. It easily swallowed the CarsGuide medium sized, 68-litre hard shell suitcase.

In terms of getting in and out, make sure you've done you warm-ups because frankly it's an athletic challenge to maintain composure and get the job done either way. Despite best efforts, I hit my head a couple of times, and aside from the pain it's worth pointing out that being a follicularly-challenged person I'm forced to display abrasions in full public view.

At $331,500, we reckon the McLaren 540C is a supercar bargain. For just on $140k less than a Ferrari 488 GTB it delivers equivalent visual drama, and isn't far behind on speed and dynamic ability.

Standard kit runs to climate control air con, an alarm system, cruise control, remote central locking, LED headlights, tail-lights and DRLs, keyless entry and drive, a limited-slip differential, leather steering wheel, power folding mirrors, four-speaker audio, and a multi-function trip computer.

'Our' car featured close to $30,000 worth of options; headline items being the 'Elite - McLaren Orange' paint finish ($3620), a 'Sport Exhaust' system ($8500), and the 'Security Pack' ($10,520) which includes front and rear parking sensors, a reversing camera, alarm upgrade and a vehicle lifter that raises the front of the car an extra 40mm at the push of a column stalk. Very handy.

And the signature orange shade follows through with orange brake calipers peeking out through the standard 'Club Cast' alloy rims, and similarly coloured seatbelts inside.

As with the related EQA, the EQB uses an asynchronous motor and a single-speed reduction gear transmission under the bonnet to drive the front axle. In the 250, it makes 140kW of power and 385Nm of torque.

Moving on to the 350 4Matic, it delivers 215kW and 520Nm, since a second permanently excited synchronous motor is fitted on the rear axle. This slashes the 0-100km/h acceleration time from 8.9 seconds to 6.2s, though both offer a 160km/h top speed.

This is despite a heavier kerb weight (2153kg, up from 2059kg). Power to weight ratio for the 250 is 68kW per tonne, compared to the 350 4Matic’s 99.9kW/tonne. That second motor sure makes a difference!

Both models use a 66.5kWh lithium-ion battery pack fitted between the axles, with a maximum 11kW AC and 100kW DC charging capability.

As with most electrified MFA2 models, front suspension is via MacPherson-style struts while the rear brings a multi-link arrangement. Steering is by electrically assisted rack-and-pinion.

Aside from you and a passenger, the most important thing sitting between the 540C's axles is the 3.8-litre (M838TE) twin-turbo V8.

Developed in collaboration with British high-tech engineering specialist, Ricardo, McLaren's used it in various states of tune across different models, including the P1, and even in this 'entry-level' spec it produces enough power to light up a small town.

In 540C trim, the all-alloy unit delivers 397kW (540 metric horsepower, hence the model designation) at 7500rpm, and 540Nm from 3500-6500rpm. It uses race-derived dry sump lubrication, and a compact flat plane crank design, favoured by Ferrari and others in high-performance engines.

While vibration damping can be an issue with this configuration, it allows a much higher rev ceiling relative to the more common cross plane arrangement, and this engine screams up to 8500rpm, a stratospheric number for a road-going turbo.

The seven-speed 'Seamless-Shift' dual-clutch transmission sends drive exclusively to the rear wheels and comes from Italian gearbox gurus Oerlikon Graziano. It's been progressively refined and upgraded since its first appearance in the MP4-12C in 2011.

Using WLTP figures, the EQB 250 has a combined consumption rating of 20.4kWh per 100km, down from the EQB 350 4Matic’s 21kWh/100km.

Maximum range is rated at 371km and 360km respectively. Note that due to challenging flood-water and torrential rain weather conditions, on-road real-world figures were not available during the launch drive.

The EQB offers varying levels of energy recuperation to help recharge the battery pack. In ‘D Auto’ it figures out the level of resistance automatically, but drivers can also choose to do this manually via ‘D+’ that provides coasting, ‘D’ that brings mild regeneration off-throttle, and ‘D—’ that activates maximising regen for close to single-pedal driving. These are paddle activated.

Cables for home charging with three-prong outlets are included – an eight metre long one plus a five metre public charging cable.

Mercedes says that using a 100kW DC charger will take an EQB from 10-80 per cent charged in 30 minutes, while an 11kW AC public outlet needs 4.1 hours and at home using a regular 3kW 10-amp socket requires at least 25 hours.

McLaren claims 10.7L/100km for the combined (urban/extra urban) fuel economy cycle, emitting 249g/km of CO2 at the same time.

For the record, that's six per cent better than the Ferrari 488 GTB (11.4L/100km – 260g/km), and if you take it easy on a constant freeway cruise, you can lower it even further.

But most of the time, we, ahem, didn't do better than that, averaging 14.5L/100km via the trip computer in just over 300km of city, suburban and freeway running.

The most remarkable thing about driving the EQB is how similar the 250 and 350 4Matic seem initially, until when push comes to shove.

Around town, both rise up to meet brand expectations. Easy and smooth off the line, acceleration is sufficiently brisk in the 250 and noticeably stronger driving the 350, as you’d expect in a two-motor EV. Progress is spirited, smooth and refined.

We're also grateful that the engineers seem to have cheekily dialled in connected and agile steering, imbuing the EQB with a likeable athletic attitude that’s just right for weaving in and out of tight traffic spots. Which is quite a feat really, given this car’s substantial size and mass.

Perhaps more surprising is how settled the ride is, no doubt aided by the sheer weight of these two-tonne-plus SUVs, as well as the standard-fitment adaptive dampers. Most bumps are quietly and effectively absorbed.

Out on the open road, the 250 remains sufficiently powerful, offering decent throttle response and quite a relaxed cruising gate. However, if you’re expecting Tesla-matching neck-snapping mid-range thrust, look elsewhere. Same applies to the other model. Though undeniably stronger throughout, not even the twin-motor 350 4Matic can be classed as especially quick.

However, while both EQBs display beautifully balanced steering that go exactly where you need them to be, only the 350 4Matic has the muscle to really explore the lofty dynamic capabilities available at higher speeds.

Across water-logged and desolate rural Victoria, the EQB behaved with exceptional athleticism given its role in life, providing outstanding steering precision, matched by brilliantly reassuring control. We’re talking planted confidence, as the 350 4Matic has the ability to really come together and move with the ebb and flow of a fast country road with outstanding aplomb. Despite teeming rain at times, the Mercedes behaved like you’d hope a swift, safe and sound grand tourer would. Who'd have figured?

Back on the highway, there was plenty of road noise intrusion coming up through the tyres, but otherwise, it seems obvious to us that though you pay more, you do get more with the twin-motor AWD version.

The best word to describe driving this McLaren is orchestration. The 540C's dynamic elements flow seamlessly together to transform its operator into a conductor guiding a well-honed mechanical orchestra through an energetic concerto.

And slipping (carefully) over the carpeted bulkhead into the driver's seat is like dropping into an ergonomic masterclass. It feels like you're putting the car on, rather than getting into it.

Like all other current McLarens, the 540C is constructed around a one-piece, carbon-fibre tub, which it calls MonoCell II. It's super stiff, and just as importantly, light.

McLaren quotes a dry weight (no fuel, lubricants, or coolant) for the 540C of 1311kg, with the kerb weight a stated 1525kg (including a 75kg passenger). Not featherweight, but with this kind of power sitting a few centimetres behind your head, it's not a lot.

The engine sounds brilliantly guttural, with lots of exhaust roar managing to find a way past the turbos.

A sophisticated launch control system means zero to licence loss is achieved in a flash (0-100km/h – 3.5sec), with jail time lurking if you ever decide to explore the 540C's 320km/h maximum velocity. And in case you're wondering, it'll blast from 0-200km/h, in just 10.5sec.

The engine sounds brilliantly guttural, with lots of exhaust roar managing to find a way past the turbos. Maximum torque is available across a flat plateau from 3500-6500rpm, and mid-range punch is strong. However, the 540C is anything but a one-trick pony, or is that 540 ponies?

The double wishbone suspension, complete with the adaptive 'Active Dynamics Control' system lets you channel all that forward thrust into huge cornering speed.

The switch from Normal, through Sport to Track progressively buttons everything down harder, and an ideal weight distribution (42f/58r) delivers fantastic agility.

Feel from the electro-hydraulic steering is amazing, the fat Pirelli P Zero rubber (225/35 x 19 front / 285/35 x 20 rear), developed specifically for this car, grips like a Mr T handshake, and the standard 'Brake Steer' torque vectoring system, which applies braking force to optimise drive and minimise understeer, is undetectable in the best possible way.

A console switchable 'Powertrain Control System' also offers three settings, and in the upper modes, shifts from the seven speed dual clutch 'box are eye-blink rapid.

The steering wheel paddles come in the form of a genuine rocker, so you're able to change up and down ratios on either side of the wheel, or one-handed.

You'll love catching a glimpse of the heat haze shimmering up off the engine in the rear-view mirror at the lights.

Hammer towards a quick corner and the reassuringly progressive steel rotor brakes bleed off speed with complete authority. Flick down a couple of gears, then turn in and the front end sweeps towards the apex without a hint of drama. Squeeze in the power and the fat rear rubber keeps the car planted, and perfectly neutral mid-corner. Then pin the throttle and the 540C rockets towards the next bend… which can't come quickly enough. Repeat, and enjoy.

But slotting everything into 'Normal' mode transforms this dramatic wedge into a compliant daily driver. Smooth throttle response, surprisingly good vision and excellent ride comfort make the McLaren a pleasure to steer around town.

You'll love catching a glimpse of the heat haze shimmering up off the engine in the rear-view mirror at the lights, and the (optional) nose-lift system makes traversing awkward driveways and speed bumps manageable.

In terms of active safety, the car's dynamic ability is one giant safeguard against a collision, and that's backed up by tech features including ABS and brake assist (no AEB, though), as well as stability and traction controls.

But if a crunching-type incident is unavoidable, the carbon-composite chassis offers exceptional crash protection with dual front airbags in support (no side or curtain airbags).

Not a huge surprise that ANCAP (or Euro NCAP, for that matter) hasn't assessed this particular vehicle.

Mercedes-Benz offers a five-year/unlimited kilometre warranty. The battery pack warranty is also industry-standard, valid for the usual eight years/160,000km.

Service intervals are every year or 25,000km. The EQB Service Plan starts at $1625 for the first three years, $2225 for four years and $2650 for five years.

McLaren offers a three year/unlimited km warranty on the 540C, and servicing is recommended every 15,000 km or two years, whichever comes first. No capped price servicing program is offered.

That's a lot of kays for a premium exotic like this, and some may not see 15,000km on the odometer… ever.
