Chevrolet Corvette vs BMW Alpina B4

What's the difference?

The Chevrolet Corvette E-Ray offers hypercar-level performance, aggressive design and brilliant dynamics at a bargain-price relative to similarly-configured Euro exotics. Blending raw V8 grunt with front-axle electric power it delivers an exhilarating drive experience.

While things like ingress and egress are a challenge and warranty coverage is modest, the car’s immense capability makes it an attractive option for anyone wanting a high-performance mid-engine machine without the astronomical price tag of a ‘traditional’ supercar.

You could almost call the B4 S the anti-M4. It's still fast and practical but from a completely different perspective. It's much more a grand tourer than the M4 and even with the Akrapovic exhaust (usually a byword for joyous, anti-social racket), subtle.

For some, the price won't matter because the Alpina delivers what they want - M4-like straight line performance without the histrionics or the uncompromising chassis. And there's also a bit of that perverse exclusivity of the styling that you won't get anywhere else.

If you asked primary school me to draw a ‘supercar’ I’d likely hand you a roughly hewn, multi-coloured wedge in Egyptian frieze-style 2D that could be interpreted as a prescient rendering of the current Corvette E-Ray.

GM has confessed that a big part of its motivation for going mid-engine with the current-gen Corvette is to help it appeal to a younger target market (maybe not under-10s) and Chevrolet has enthusiastically embraced the low nose, wide high-tail stance. You’re not going to miss it.

The E-Ray, like its track-focused Z06 sibling, is longer (+58mm) and wider (+92mm) than the standard Corvette Stingray, with huge air intakes in the nose and deep gills behind the doors.

Its distinctly angular design retains enough Corvette DNA to keep the C8 in the family. The headlights are reminiscent of the C7 that preceded it and the dual tail-light design is a neat reinterpretation of that signature element. A clear engine lid showcases the longitudinally mounted V8’s bright red engine cover.

Far from a clean or curvaceous shape, the E-Ray is all business with function driving its fighter jet form. And that carries over to the interior with the driver-focused cockpit making no apologies for concentrating almost exclusively on the person behind the wheel.

Multiple screens wrap around the instrument binnacle with the flat top and bottom steering wheel affording a clear view of them all.

The jagged lift-up gear selector controls would be right at home in an F-22 Raptor and despite the layout’s relatively fussy look it works super-well ergonomically, with clearly marked buttons (haptic and physical) easy to sight and operate.

Alpina has always had a particular aesthetic that could uncharitably be termed as mid-'80s West German - all set square angles and body graphics. Think David Hasselhoff's Berlin Wall look. The company has never really deviated from adding squared-off body bits to the various BMWs it has rebadged under its long-running agreement.

For the B4S, Alpina adds the signature billion-spoke alloy wheels (only a slight exaggeration), a new front splitter complete with Alpina lettering, a weirdly proportioned boot lid lip spoiler and - not even joking - pinstripes. Like I said, mid-'80s West German. You can still recognise the sleek 4 Series Coupe but perhaps the worst of it is the super-sized, wonky-looking ALPINA B4S on the boot.

Inside is rather more restrained apart from the ill-fitting Alpina plaque under the climate control. Again, it's all 4 Series in here, with the lovely Merino leather liberally applied across the cabin. Less lovely is the wood on the door pulls and console but the door cards have an oddly appealing woven leather which looks and feels good.

Sadly the standard 4 Series steering wheel is along for the ride. There's nothing wrong with it - although the Alpina logo does look out of place - but if I were a product planner, I'd beg for the lovelier M wheel.

Practicality is a relative concept when you’re looking at a two-seat, mid-engine sports car, which means the Corvette E-Ray is not functional in the Kia Carnival sense. But there are some concessions to the need to store things inside it.

In terms of storing people, getting in and out of a C8 Corvette isn’t exactly straightforward. The car sits close to the ground, which despite decent door apertures, means to gain access you’re lowering yourself across and into the heavily bolstered seats using an ungainly, vaguely yoga-style technique. Same goes on exit with more than a little grunting required to hoick yourself out of the car. Not an easy proposition for a daily driver.

Once inside, headroom for me at 183cm is good and for storage there are slim pockets in the doors (with no scope for bottles), two cupholders in the centre console and an oddments tray ahead of them. The glove box is a good size, a lidded box between the seats houses USB-A and USB-C outlets and there’s an awkward-to-use upright wireless phone charging slot between the seat backrests.

Boot volume is 204 litres, unless you’ve removed the roof panel and clipped it into its storage position there. A surprisingly easy process, by the way. If that’s the case you’ll be leaning more heavily on the 142-litre frunk. Overall storage capacity of around 350L is pretty handy for a car of this type.

Not surprisingly, given the scale of this car’s wheel and tyre package, there’s no spare. The Michelin Pilot Sport 4S tyres are run-flats.

And substantial practicality points go to the front lift system which, via the press of a console button, rapidly raises the car’s nose by 50mm to help avoid driveway and speed bump scrapes.

If you're in the front, you're in luck - it's a comfortable place to be, with plenty of leg and headroom. Down back isn't terrible despite the coupe roofline. The two seats are nicely shaped for maximum comfort and separated by an odd plastic tray. The fold-down armrest has two cupholders.

Front seat passengers score a pair of cupholders (bring the total to four for the car) and the long doors will hold a bottle each.

The boot swallows a reasonable 445 litres, which isn't at all bad.

If you thought BMW don't mess about when pricing up its cars, you best strap yourself in. The 440i-based B4S starts at a solid $149,900. That's $48,000 more than the 440i and significantly more than an M4 Pure. But there's plenty of gear on offer and some genuine, bespoke Alpina additions.

Standard are 20-inch signature Alpina alloys, 16-speaker harmon kardon-branded stereo with DAB, super-soft Merino leather everywhere, dual-zone climate control, around-view cameras, reversing camera, sat nav, keyless entry and start, front and rear parking sensors, active cruise control, heated and electric front seats, head-up display, auto headlights and active LED headlights, LED taillights and electric sunroof.

The stereo and sat nav are run by BMW's iDrive. It's a cracker of a system and almost gets away without Apple CarPlay and Android Auto. The absence of such simple pleasures at this price point is a bit lame, but here we are.

The Corvette E-Ray is powered by a mid-mounted 6.2-litre, naturally aspirated ‘LT2’ V8 featuring dry sump lubrication, a billet steel crank, forged conrods and variable valve timing for 369kW (at 6450rpm) and 637Nm (at 5150rpm).

It sends drive to the rear wheels via an eight-speed dual-clutch auto transmission with (carbon) paddles on the steering wheel for manual shifting.  

A single 119kW/170Nm electric motor on the front axle contributes to total outputs of  488kW/806Nm and delivers ‘eAWD’. 

Claimed 0-100km/h acceleration time is a sizzling 2.9 seconds.

A lot of your extra money turns up under the bonnet. These days the 440i packs BMW's slick B58 turbo straight six and the B4S does likewise. The boys from Buchloe in Bavaria (there are certain to be women there, too, I just liked the alliteration) added a pair of Alpina-spec turbos to generate a whopping 324kW and, more importantly, 660Nm. Alpina says 600Nm (the max torque figure of the brilliant M4 CS) is available from 2000-5000rpm, while the full 660Nm is available from 3000 to 4500rpm.

The M4 Pure has 317kW and 550Nm from the S55 straight-six. Just so you know.

Like the 440i but unlike the M4, the B4S employs the dependably brilliant eight-speed ZF automatic found throughout the BMW range.

The Corvette E-Ray’s official fuel consumption figure for the combined (urban/extra-urban) cycle is 11.5L/100km.

The car’s Active Fuel Management system is able to subtly drop four cylinders under light loads, a small V4 (rather than V8) light on the dashboard the only clue this sleight-of-hand trick has been performed.

Auto stop-start is also standard, although we admit to switching it off (via a haptic button on the dash) most of the time. And purely in the name of science and fully exploring the car’s performance potential we may have leaned into the E-Ray’s dynamic abilities more than once.

Overall, across a week of mainly city and suburban running with some freeway sections thrown in, we recorded an on-test average of 13.5L/100km, which is still more than acceptable for this type of performance car. 

Brim the 70-litre tank with minimum 95 RON premium fuel and using our real-world figure you can expect a driving range of around 520km.

The E-Ray features a 1.9kWh lithium-ion battery, self-replenished from coasting and braking, allowing an EV-only (and neighbour-friendly) ‘Stealth Mode’ for four to six kilometres at a maximum of 72km/h. 

And there’s a ‘Shuttle Mode’ (not suitable for public roads) which also engages just the front axle on electric power for moving silently around a driveway or into a garage to a speed of 24km/h.  

Alpina quotes 7.9L/100km on the combined cycle and we went through the premium unleaded at the rate of 11.7L/100km. I enjoyed myself, so that's not a terrible result.

Let’s get the acceleration thing out of the way. The Corvette E-Ray is obscenely fast. If you’re determined to bend the space-time continuum, it’s keen to assist.

Claimed 0-100km/h time is just under three seconds but on a closed track using launch control we’ve previously recorded a time of 2.4sec, which is hypercar territory.

The big V8’s furious roar is amplified by the standard performance exhaust and the dual-clutch auto is a slick, positive, high-quality unit. Manual shifts via the wheel paddles are rapid-fire.

Suspension is by forged alloy double wishbones front and rear with magnetic adaptive damping standard, the latter allowing you to dial in Sport, Touring, Track and Weather modes as well as two customisable settings - MyMode for everyday driving and the performance-focused Z Mode. 

Weather optimises the car’s systems for slippery conditions, as its name implies, and Track is best left for the circuit as it’s unbearably harsh on anything less than a billiard table smooth surface. Sport is more liveable but the pick is Touring which retains the car’s fundamental agility while providing excellent compliance.

Shudder over patched suburban roads in Sport then switch to Touring to illustrate an amazingly forgiving ride.

Despite its aluminium-rich space frame, the E-Ray still weighs in at 1800kg but it responds like a lightweight. The steering is brilliantly precise without being overly sharp and road feel is superb. In terms of cornering, the C8 Corvette is the quintessential apex predator. 

Thanks in no small part to an electronic limited slip differential the E-Ray puts its power down on corner exit with impressive force and grip from the monster Michelin Pilot Sport 4S rubber is prodigious. 

The tyres measure 275/30x20 at the front and no less than 345/25x21 at the rear, bearing in mind a current F1 car’s rear tyres are 375mm across the tread.

Brakes are also professional grade with carbon ceramic rotors (398mm fr / 391mm rr) clamped by Brembo six-piston alloy calipers at the front and four-piston units at the rear. While some carbon set-ups need to be at a high temperature for optimal performance there are no such worries here. The E-Ray washes off speed with prodigious yet satisfyingly progressive power. 

Worth noting if you’re a track day demon, there’s an ‘Enhanced Performance Data Recorder’ and ‘Performance App’ that jointly provide everything from side-by-side video analysis and graphical data displays to tyre temp and pressures and even coaching tips.

‘Performance Traction Management’ also allows you to fine-tune traction and stability controls to suit specific track conditions.

Under the heading of miscellaneous observations; the GT2 seats are grippy yet supremely comfortable, an 11.1m turning circle is sizable and over-the-shoulder rear three-quarter vision is limited, although there’s enough camera coverage to minimise the problem for parking. 

One of the key differences between the B4 and M4 is the ride. While the M4 can crash over bumps and generally be a little hard to live with, the crew in Buchloe have gone after a much more plush ride. And in that they have succeeded because the B4 S is a mighty fine cruiser. Bumps are dismissed with a haughty disdain, even Sport + silliness doesn't completely write-off ride quality.

Very impressive too, is the steering. While still not at Lotus Elise levels of feel (few cars are), the Alpina tweaks connect the your palms to the road with more clarity than what you'll find in the 440i or M4. Where the M4 particularly adds too much weight, the 440i is a bit more circumspect in that regard.

And then we come to the engine. The B58 six is a belter, better even than the N55 that preceded it. It's still a 3.0-litre straight six but is part of BMW's modular engine family that starts with a 1.5-litre triple in the Mini and 1 Series. The Alpina-spec turbos are noisier, the Akrapovic exhaust lighter and also noisier. It doesn't have the all-out crackle and pop of an Audi or Merc (perish the thought), but when you're on it, the B4 means business. The 660Nm of torque, available over a wide rev range, delivers a steel fist wrapped in a velvet glove and bubble wrap - the speed builds rapidly but smoothly. 

The approach to the chassis tune seems to be based on the driving talents of mere mortals on normal roads, which is kind of like the 440i. It's terrific fun to drive hard but it's very forgiving and patient. The great thing about it is that you wouldn't think twice about jumping in it for the long haul, so comfortable and quiet is the cabin. The M4 will leave it for dead on a winding road, but that's perfectly fine.

One irritant is the replacement of the admittedly cheap BMW gearshift paddles with weirdly non-tactile buttons. They're not particularly easy to use and, probably worse for a sporty car, unsatisfying. It's an odd detail with which to go off the reservation. Cheeringly, the eight-speed ZF is its usual perfect self, so you don't have to worry too much about manual mode or go old school and use the shifter.

The Alpina ships with six airbags, ABS, stability and traction controls, ABS, stability and traction controls, forward collision warning, forward AEB, road sign recognition and active cruise control.

There are also two ISOFIX points in the rear. Neither the Alpina nor the 4 Series has an ANCAP safety rating.

GMSV’s warranty cover for the Corvette sits at three years/100,000km which is woefully under-done, even in the context of high-dollar sports cars.

For example, Aston, Ferrari, Lambo, McLaren and Porsche, while still at three years, offer unlimited-kilometre cover.

Service is recommended every 12 months/12,000km, the average annual price for the Corvette coming in at around $1100 over the first few years, largely because the first and every second service thereafter is a major one, including things like a transmission fluid change.

That’s way lower than most mid-engine Euros and it’s important to note service price will vary according to the car's use, different state and territory labour rates and other factors.

There are around 55 GMSV dealers in Australia focused on capital cities as well as major regional and rural centres.

Alpina offers a two-year/unlimited-kilometre warranty which is a bit behind the times and not in keeping with the price point. Servicing is another matter altogether and you're subject to your dealer's standard charges for servicing.
