Costs & verdict

There are few logical reasons to buy a six-figure, 200mph four-door coupé like the Alpina B8 Gran Coupé, but ​​you know that already, don’t you? Ultimately, this is a car you buy with your heart, not your head, but let’s investigate the costs anyway...

If you’re weighing up your options, you can buy an <a href="https://www.whatcar.com/audi/rs-7/hatchback/review/n17275">Audi RS7 Sportback</a>, BMW M8 Gran Coupé or <a href="https://www.whatcar.com/mercedes-benz/e-class/saloon/review/n17226">Mercedes-AMG E63</a> for quite a bit less, but compared with the cost of a <a href="https://www.whatcar.com/porsche/panamera/hatchback/review/n17212">Porsche Panamera</a> Turbo S E-Hybrid or <a href="https://www.whatcar.com/bentley/flying-spur/saloon/review/n17297">Bentley Flying Spur</a>, the low-volume B8 looks competitively priced.&nbsp;

The running costs will be rather less reasonable. That V8 engine won’t be easy on tyres or fuel, and the official fuel economy of 25.4mpg is the stuff of fantasy, because if you use the engine as it’s intended, you’ll be lucky to see half that figure.&nbsp;

You’ll need huge reserves of cash to run a B8 as a company car, too. The substantial list price and CO2 emissions of 254g/km place the car in the top 37% band, meaning benefit-in-kind tax payments will be astronomical. That said, the same issue faces buyers considering the M8 or E63.

From gold pinstriping to contrasting heated and cooled Lavalina&nbsp;leather seats, when it comes to options, the world is your oyster. However, it is a little disappointing that must-have items such as the high-performance brake system and CNC milled aluminium gear-shift paddles are not standard fare considering the substantial list price.&nbsp;

The B8 hasn’t been safety tested by <a href="https://www.whatcar.com/news/the-safest-cars-on-sale-today/n19724">Euro NCAP</a>, but you do get a range of safety aids as standard. These include automatic emergency braking <a href="https://www.whatcar.com/news/what-is-aeb-and-how-does-it-work/n3283">(AEB)</a> and lane-keeping assistance.

BMW supplies Alpina with almost all the constituent parts required to build a whole range of cars, but not everything is up for grabs.

The B8 Gran Coupé and the M8 Gran Coupé may both be powered by 4.4-litre V8s, but the M8’s highly specialised power unit is a jealously guarded device, so the B8 has to make do with the engine from the lesser <a href="https://www.whatcar.com/bmw/m8/sports/review/n20281">BMW M850</a>. Not that that's&nbsp;prevented Alpina from getting this relatively humble V8 to conjure up a cauldron full of seriously explosive performance.

Chief among Alpina’s efforts is a pair of ‘optimised’ turbochargers that ramp up the power in the V8 from a not inconsiderable 523bhp in the M850 to a cork-popping 613bhp, putting it just 3bhp down on the M Division’s own M8.

<a href="https://www.whatcar.com/make/bmw-alpina">Alpina</a> hasn’t just turned up the boost and shut the bonnet, though. Power increases on that scale demand myriad engine and gearbox reinforcements, along with considerable cooling upgrades. The B8 gets a 50% increase in cooling capacity compared with&nbsp;an M8 and a beefed-up eight-speed gearbox.&nbsp;

That all translates into a car that will sprint from 0-62mph in just 3.4 seconds – half a second up on the M8 – but raw performance figures don’t tell the whole story. You see, the way the B8 delivers its power is totally different from what you experience in the M8.&nbsp;The engine in the M car almost feels as though it does without turbochargers thanks to its revvy nature and near-instantaneous accelerator responses, whereas the Alpina feels more old school and exhibits a touch more lag before the turbos wake up.&nbsp;

On a track, this hesitation could cost you a few tenths of a second, but on an open road, the anticipation as the boost builds before everything goes warp speed gives the B8 real character. We just wish that the sports exhaust was a little louder – not as anti-social as the&nbsp;<a href="https://www.whatcar.com/mercedes-benz/e-class/saloon/review/n17226">Mercedes-AMG E63 S</a>, but it could do with a little more edge like the&nbsp;<a href="https://www.whatcar.com/porsche/panamera/hatchback/review/n17212">Porsche Panamera</a> Turbo S has.&nbsp;

This relaxed nature also extends to the way the B8 behaves in bends. The steering isn’t as quick as the rack in the M8, but the wheel’s weighting is consistent and nicely judged, while the bespoke suspension feels better set up for UK roads. Where the stiffly sprung M8 gets thrown offline by mid-corner bumps, the B8 simply shrugs them off, and there is none of the pillar-to-post shimmying that makes the M8 rather tiring on pockmarked roads.&nbsp;

Our only complaint is that at low speeds, the B8 does occasionally thump over sharp-edged potholes, which&nbsp;the&nbsp;<a href="https://www.whatcar.com/audi/a8/saloon/review/n21914">Audi S8</a> – with its triple chamber air suspension – does a better job of smoothing out. But at a cruise, we’re pleased to report that tyre and wind roar are minimal.

“Simplicity is the ultimate sophistication”. Apple founder Steve Jobs once used the Leonardo Da Vinci phrase as the basis of an early Mac advertising campaign, but we reckon it would be even better suited to Alpina – and specifically the Alpina B8 Gran Coupé.&nbsp;

You see, BMW supplies cars to both its in-house motorsport division ‘BMW M’ and small boutique tuning house Alpina, but what results from each organisation is very different.

It’s best to think of M cars as&nbsp;hardcore, track-focused models with slightly ostentatious styling. <a href="https://www.whatcar.com/make/bmw-alpina">Alpina</a>, on the other hand, is all about long-legged performance, long-distance comfort and understated design.&nbsp;

So while BMW's M8 Gran Coupé looks like a pumped-up cage fighter with its bulging bumpers, chiselled mirror housings and a unique widebody, the B8 looks like Bond in a Brioni suit. Sure, the B8 gets its own <a href="https://www.whatcar.com/best/best-performance-cars-2022/n23035">performance car</a> embellishments – a chin spoiler, a boot-mounted spoiler, a rear diffuser and sundial alloy wheels – but it’s a much cleaner and more flowing design.&nbsp;

Conversely, under the skin, it looks as if there’s a fair bit of mechanical symbiosis going on. Both cars employ twin-turbocharged V8 engines and both use four-wheel steering and traction-enhancing four-wheel drive. They also have mind-boggling electronic intervention systems&nbsp;in an effort to maximise power delivery and enhance cornering stability. But as you’re about to find out, not all is at it seems.&nbsp;

Over the next few pages, we’ll compare the Alpina B8 Gran Coupé with rivals including the M8 Gran Coupé, the <a href="https://www.whatcar.com/audi/rs-7/hatchback/review/n17275">Audi RS7 Sportback</a> and <a href="https://www.whatcar.com/porsche/panamera/hatchback/review/n17212">Porsche Panamera</a> Turbo S across areas such as performance, interior quality, practicality and running costs.

Other than the bespoke blue speedo and rev counter displays, and Alpina-embossed threshold kick plates that greet you when you open the doors, there are very few differences between the Alpina B8 Gran Coupé and the <a href="https://www.whatcar.com/bmw/m8/sports/review/n20281">BMW M850</a> it's based on. But that’s no bad thing.

Material quality and the overall fit and finish are first class, and <a href="https://www.whatcar.com/make/bmw-alpina">Alpina</a> has done just enough to lift the interior to a point where it feels special.&nbsp;For example, the B8 gets the same Merino leather as the normal M850, but it's available in punchier colours – in the case of our test car, an Ivory White and Night Blue combination.

The steering wheel is finished in Alpina Lavalina leather, which feels more supple and grippier than an M850's wheel, and the optional all-aluminium steering-wheel paddles are an absolute must. You even get a small plaque between the front seats telling you what number car you’ve purchased.&nbsp;

The infotainment system, meanwhile, is a masterpiece of integration and usability. BMW’s latest-generation iDrive set-up beats its rivals’ systems by a mile in two important ways.

Firstly, its menus are generally logical and very responsive. Secondly, by sticking with a rotary controller and shortcut menu buttons (instead of the touchscreen-only interfaces that the <a href="https://www.whatcar.com/porsche/panamera/hatchback/review/n17212">Porsche Panamera</a> and <a href="https://www.whatcar.com/audi/rs-7/hatchback/review/n17275">Audi RS7 Sportback</a> employ), it’s far less distracting to use while driving. The B8 has&nbsp;<a href="https://www.whatcar.com/advice/owning/what-is-apple-carplay/n1193">Apple CarPlay</a>/<a href="https://www.whatcar.com/advice/owning/what-is-android-auto/n1194">Android Auto</a>&nbsp;smartphone mirroring fitted as standard.&nbsp;

As in the M850, the steering wheel and seat are both electrically adjustable, the seat is comfortable and nothing feels out of kilter. There’s a head-up display as standard, which beams plenty of information into your sightline, and the digital dials can be set up in all manner of styles and display all sorts of useful info.

Visibility isn’t perfect, though. The front pillars are quite fat and tend to obscure your vision through tight corners, although the B8's rivals aren't much better in this regard, while the rear screen is fairly shallow.

Front and rear parking sensors are standard, though, as is a rear-view camera (a 360-degree camera is optional). The B8 comes with&nbsp;ultra-bright&nbsp;adaptive LED headlights, but if LEDs are a bit ‘last season’ for you, laser lights are available an option.

An even better high-performance compromise between pace, handling and usability than the closely related BMW M8 Gran Coupé

Alpina B8 Gran Coupé

Space in the front of the Alpina B8 Gran Coupé is fine for two taller adults and certainly on a par with the competition.

It’s quite broad inside, too, so you can spread out across the centre armrest without spilling into your passenger’s space. There are also plenty of storage options for your odds and sods dotted about the interior.

Now for the important question: how spacious is the rear? Well, you get two proper seats and an occasional middle seat that’ll be quite awkward to sit on for long periods (its occupant has to straddle a large hump in the floor).

The two outer seats are supportive and six-footers will have enough legroom to sit behind tall front-seat occupants. Headroom is marginal though, with the <a href="https://www.whatcar.com/porsche/panamera/hatchback/review/n17212">Porsche Panamera</a> and <a href="https://www.whatcar.com/audi/rs-7/hatchback/review/n17275">Audi RS7 Sportback</a> both offering more space for your bouffant.

You can fold down the rear seatbacks in a 40/20/40 configuration using handy release levers in the boot. Doing so gives you a fairly flat extended load bay, and with the rear seats up there’s room for around five carry-on suitcases – one more than we could fit in the Panamera but three less than we got in the RS7.

The Alpina B8 strikes a more convincing compromise between everyday usability and staggering performance than the M Division’s own M8 Gran Coupe. It’s Alpina at its very best.

<h2>What we're looking for:</h2><ul><li>Entertainingly agile handling</li> <li>Eye-widening acceleration</li> <li>Fruity exhaust note</li> <li>Punchy and characterful engine</li> <li>Great driving position</li> <li>Everyday usability</li></ul>

The best performance cars combine sports car-rivalling acceleration with&nbsp;engaging handling. However, they also retain the&nbsp;impressive everyday usability of the conventional saloons and estates on which they're based.

Performance car

<h2>What we're looking for:</h2><ul><li>Strong performance</li> <li>Good balance between ride and handling</li> <li>Excellent build quality</li> <li>Decent practicality</li> <li>Sophisticated interior</li></ul>

Coupés are all about style, but while practicality undoubtedly takes a back seat to aesthetics, these cars still need to be easy to live with on a daily basis. It’s this that distinguishes a coupé from an out-and-out sports car.

Fortunately, there’s a wide range of style-focused models available, and you don’t even need to spend silly money to buy or run one.
