Cadillac Lyriq vs Mercedes-Benz Eqb250

What's the difference?

The Lyriq Luxury combines handsome styling and luxurious appointments with responsive yet supple ride quality, the choice of relaxed driving or exhilarating performance as desired and a decent driving range. Its lack of towing ability may be a deal breaker for some, but it's certainly worthy of consideration by prestige SUV buyers with a penchant for electric power and (for now at least) sub-$100K drive-away pricing.

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 Lyriq has a generous 3095mm wheelbase, is more than five metres long (5005mm) and almost two metres wide (1977mm, including mirrors). Its 1620mm roof height is relatively low for a large SUV, resulting in a sleek and sporty profile combined with a muscular surefooted stance fronted by a finely-etched solid grille.

It rides on five-link independent suspension with GM’s ‘passive plus’ dampers, plus there’s electric power-assisted steering and big Brembo disc brakes in each corner featuring classy Cadillac scripts on the calipers. Turning circle is 12.1 metres, which is to be expected for a car of this size.

The interior design is an elegant blend of soft-touch materials and discreetly textured surface finishes with an emphasis on chrome and satin chrome highlights. It’s also spacious as you’d expect, with the panoramic sunroof creating a bright and airy feel.

We applaud Cadillac’s adherence to tradition with physical buttons and knurled dials and knobs for controlling key cabin and driving functions, in preference to annoying and distracting touchscreen menus. There’s also nice attention to detail with small jewel-like Cadillac emblems and scripts contributing to its prestige look and feel.

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.

The Lyriq’s 2687kg kerb weight (largely due to its hefty propulsion battery) and 3200kg GVM results in a modest 513kg load capacity, which could easily be used up by five large adults before you could think about loading their luggage. It’s also not rated for towing in Australia which limits its appeal as a recreational vehicle.

Driver and front passenger enjoy palatial space and comfort plus ample storage with a bottle-holder and bin in each door. There's also a large glove box, pop-out drawer in the dash and a ‘floating’ centre console equipped with a lower tray, three USB-C ports, a 12V socket, wireless phone charging and a felt-lined box at the back with padded lid that doubles as an elbow rest.

The rear doors open wide for easy entry to the rear bench seat which even for tall people (I’m 186cm) offers ample room for knees and feet, enhanced by a flat floor with no transmission tunnel for centre passengers to straddle.

However, the top of my head brushes the roof lining and the unusually high floor height (we assume caused by the underfloor battery) results in raised thigh angles that concentrate more weight on the lower back.

Given the rounded lower backrest cushions, which integrate with the ISOFIX child seat anchorages in the outer seating positions, also protrude into a passenger's lower back region, the rear seat provides less than ideal comfort for tall passengers in contrast to the sublime luxury up front.

Even so, rear passenger storage is well catered for with a bottle-holder in each door, pockets on both front seat backrests and two cupholders in the fold-down centre armrest. The rear of the centre console offers two more USB-C ports, adjustable air vents and adjustments for numerous comfort settings.

The power tailgate provides access to the fully carpeted rear luggage area, which offers up to 793 litres (almost 0.8 cubic metres) of load volume with the rear seats upright and up to 1722 litres (almost 1.8 cubic metres) with the seats power-folded flat. This provides a versatile space for carrying everything from a mountain bike to flatpack furniture.

The luggage area also has four tie-down hooks, a 12V socket and a hinged floor section which when opened reveals an underfloor bin ideal for storing charging cables (see image).

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.

Tricky one, this.

Kicking off from $87,800 (all prices are before on-road costs), the EQB 250 front-wheel drive is nearly $24,000 more expensive than the 1.3-litre turbo petrol-powered GLB 200 FWD equivalent.

From a numerical power-output point of view, however, the GLB 250 4Matic (which adds a 2.0-litre turbo petrol engine and all-wheel drive) only costs $10,265 less, which evens things out a bit more.

But wait. To match the GLB 250 4Matic spec, you’ll need to tick the $2900 third-row seats option box in the EQB 250, while AWD is unavailable, even as an option.

An electrified future comes neither cheap nor without compromise, no matter how much you frame it.

At least that $87,800 (which sits neatly between the EQA and EQC EV SUVs) does bring some interesting technology, starting with a 140kW electric motor mounted up front, as well as a sizeable 66.5kWh battery with a rated range of up to 371km (WLTP).

For more power and AWD, you’ll need the EQB 350 4Matic priced from $106,700, adding a second, rear-mounted electric motor for all-wheel-drive traction, upping the power output ante to 215kW, though range drops slightly to 360km.

But the latter is not available in seven-seat form as in some overseas markets, due to weight-related packaging safeguards. Sorry. It’s 250 or nothing if you need a third row.

On the safety front, you’ll find Mercedes’ Driver Assistance Package that includes autonomous emergency braking, blind-spot monitoring, lane-keep assist and adaptive cruise control, as well as evasive steering and a ‘Parking Package’ featuring front and rear parking sensors and a surround-view camera.

Both models also boast LED headlights with high-beam assist, keyless entry/go, a Nappa-sheathed leather wheel, two 10.25-inch digital screens (for instrumentation and multimedia touchscreen), artificial leather upholstery, electric and heated front seats, dual-zone climate control, ambient lighting, ‘Hey, Mercedes’ voice control, a 10-speaker audio system, digital radio, wired Apple CarPlay/Android Auto, a wireless smartphone charger, a sensor-activated powered tailgate and alloy wheels (19-inch on 250 and 20-inch on 350 4Matic).

Keep in mind too that adaptive dampers are standard across the range.

Along with that second motor and AWD, the EQB 350 4Matic also adds a panoramic sunroof, sports seats, microfibre trim inserts, a flat-bottom steering wheel, illuminated door sills, a top-stitched dash and an AMG body kit.

For its first year on sale, the Edition 1 ($9100 extra on 250 and $3900 more on 350 4Matic) ushers in the AMG body kit on 250, Gold Rose 20-inch alloys, a Night Package with darkened highlights, illuminated sills, unique colour leather trim and vents, a different key, AMG mats and backlit interior elements.

Buyers of the EQB 250 can also choose other packs including an AMG Line Sports Package for $4300 and a $3000 Vision Package brandishing a Burmester audio upgrade and sunroof, while both models can be had with a $2500 MBUX Innovation pack offering a head-up display, MBUX Interior Assist that ‘senses’ hand gestures for the touchscreen and other functions, as well as MBUX Augmented reality for the standard navigation system.

At these prices, we'd argue they ought to be standard on every EQB...

There’s also a Mercedes-endorsed Wallbox option from $1710 if your home/work residence qualifies, bringing a Type 2 AC Charger, 22kW, single-phase and three-phase charging. A free Chargefox subscription is also expected to be announced shortly.

Direct, all-electric EQB rivals are very thin on the ground. Those optional third-row seats on the 250 are unique in the sub-$100K EV SUV field, with only the larger and more-expensive Tesla Model X offering the same. For now.

The EQB 350 4Matic, meanwhile, might offer a surprising amount of space and practicality, but at its six-figure starting price, it seems expensive for what you get.

The Lyriq features drive units with single-speed transmissions located at the front and rear which provide permanent all-wheel drive. Each is equipped with an electric motor, which combined produce 388kW of power and 610Nm of torque. There are also numerous selectable drive modes. Claimed 0-100km/h acceleration time is a rapid 5.3 seconds.

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.

GMANZ claims official combined consumption of 22.5kWh/100km and up to 530km of driving range from the Lyriq’s 102kW lithium-ion propulsion battery.

When we collected our test vehicle the dash display was showing 100 per cent charge and an estimated driving range of 583km.

We drove 239km over five days and still had 52 per cent charge and 300km of range remaining when we did an overnight charge at home using the supplied AC charger with a domestic three-pin plug.

However, after 15 hours the charge only increased from 52 to 65 per cent for just 76km of extra driving range, so we would recommend installing a dedicated wall box for faster home charging.

In total we covered 297km across our usual mix of suburban, city and highway driving with average energy consumption just under the Cadillac's official figure, so based on our test results a driving range of around 500km per charge is credible.

GMANZ claims 7.4kW AC charging can add up to 43km of range per hour, which increases to 94km with 22.1kW charging. And up to 128km of range can be added in just 10 minutes using 190kW DC fast charging.

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.

The driving position is supportive and comfortable with multiple power-adjustment of the seat and steering wheel ensuring people of most heights and girths can enjoy luxurious travel.

The low dashboard height ensures vision to the front of the bonnet and its array of physical buttons, knurled dials and knobs minimise touchscreen use, which makes driving far less distracting than having to search through digital menus.

It’s very quiet given its electric drivetrain. Most noise emanates from the tyres but that is also minimised by the audio system’s noise cancellation technology and the cabin’s effective acoustic insulation.

Ride quality and handling are excellent thanks to the Lyriq’s suspension refinement and close to an ideal 50-50 weight distribution mostly influenced by the positioning of its drive battery.

This battery’s considerable heft (we reckon it weighs at least half a tonne) also creates ample sprung weight to assist the suspension in smoothing out bumps and its underfloor location ensures a low centre of gravity for surefooted cornering.

Standing start acceleration is more than impressive for a luxury car weighing almost 2.7 tonnes, with instantaneous torque from its two electric motors helping to propel the Lyriq to a neck-straining 100km/h in about five seconds.

This spirited response creates a sporty and engaging drive that belies the vehicle’s weight, particularly in Sport mode with its sharper throttle response and firmer steering feel.

We also like the choices for regenerative braking which include ‘One Pedal Driving’ mode with 'Normal' and 'High' settings, both of which make the quartet of disc brakes largely redundant (the High setting feels like heavy pedal braking) while optimising battery charge. There’s also a small paddle on the steering wheel which increases regenerative braking in response to the amount of finger pressure applied to it.

Our only criticism from a driver’s point of view is the absence of a head-up display (HUD) and traffic sign recognition (TSR), both of which are notable omissions for a prestige vehicle in this price range.

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.

Tested way back in 2019, an EQB 250 in Europe scored a five-star crash-test rating with EuroNCAP, and that result is accepted by ANCAP.

Safety features include Mercedes’ Driver Assistance Package that includes autonomous emergency braking, blind-spot monitoring with an exit warning that alerts the driver of approaching cyclists or vehicles if the door begins to open into their path, lane-keep assist and adaptive cruise control, as well as evasive steering and a ‘Parking Package’ featuring front and rear parking sensors and a surround-view camera.

The AEB with forward collision warning works between 7km/h and 200km/h, and offers pedestrian and cyclist protection day or night. The Active Lane Assist tech operates between 60km/h and 200km/h.

The EQB has nine airbags, made up of front, pelvis side and window bags for driver and front passenger, side airbags for rear occupants and a knee airbag for the driver, while the side curtains cover third-row occupants where relevant.

Along with a trio of child-seat tether anchorages, the EQB’s rear seat base is fitted with two ISOFIX attachments, and another two if the optional third-row chairs are present. That’s pretty rare, even in people movers.

Finally, the EQB makes a sound for pedestrians and other warns other road users that’s audible at speeds below 20km/h, plus a reversing tone.

The Lyriq comes standard with a five-year/unlimited km warranty including five years' of roadside assist, while the propulsion battery is covered by a separate eight-year/160,000km warranty.

Scheduled servicing is every 12 months/12,000km whichever occurs first, with costs for the first five years of scheduled servicing or five scheduled services included in the vehicle’s purchase price. These servicing terms are generous for this segment, although some rivals offer similar enticements like Audi’s six-year ‘complimentary’ servicing for its Q8 e-tron.

GMANZ has a national network of 45-50 dealerships across most capital cities and some regional areas but not all offer vehicle servicing.

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.
