Alpina B6 (E63) | Spotted

No matter how special the V10-powered M6 was, it wasn't the ultimate 6er - this Alpina was


Is there a more unloved BMW in recent memory than the 6 Series? Possibly, and feel free to put forward a better candidate in the comments, but ever since the 6er name was revived in 2003 with the E63, it’s always played second fiddle to the 5 Series it shares its underpinnings with. Obviously, a four-door saloon is going to find more buyers than a two-door GT, but when M shoved a screaming V10 in the both of them, people flocked to the M5 while largely turning a blind eye to the M6. 

So deep was the 6 Series in no-man's land that it was eventually poshed up and rebranded as the 8 Series, pushing it deeper into the luxury market. But that doesn’t mean the old 6 didn’t make a decent GT. While the original M6 was a touch more focused than the rivals such as the Aston Martin V8 Vantage and Jaguar XKR, the softer 650i made for a superb cruiser while the straight-six-powered 630i paired with a manual served as a delightfully old-school sports coupe. Then, of course, there were the Alpina cars, this B6 being one of hardly any produced. 

Pinning down a production number is easier said than done, especially as this particular car is a Japanese import, but the Alpina Register has just 13 cars (seven B6 and six B6S) down for the UK market. Hard to imagine that number’s significantly higher in other markets, so it’s a mighty, mighty rare thing indeed.

Now, when faced with the choice between a V10 coupe with an M badge on the back, or a V8 with slightly more restrained looks, it’s understandable why buyers at the time would have leaned towards the former. But the B6 might just be the ultimate version of the E63 (well, there was an even more punchy B6S, but they're even rarer). The 4.4-litre N62 V8 was carried over from the 650i it’s based on, only heavily reworked with a bespoke block by Steyr, Mahle pistons, an upgraded crankshaft and an ASA supercharger, while an Akrapovic exhaust supplied the backing vocals. That all saw power rise to 500hp, which was bang on what the M6’s V10 could muster, though the Alpina’s 516lb ft of torque was a sizeable jump over the M car.

Then there’s the Alpina’s better fuel economy, the slicker six-speed automatic gearbox rather than the M6’s clunky SMG, and a bespoke suspension setup that’s said to be far more cosseting than the M’s. And the looks? The E63’s ‘Bangle bum’ was divisive from the get-go, up there with the Z3 M Coupe and G80 M3/G82 M4, and sticking deeper skirts, a faux splitter and bigger boot spoiler does little to lessen 6’s visual impact. But finished in Alpina Blue with a silver Deco pack and those wheels, it really does look the business.

It’s in great condition, too. The import sheet says it’s a Grade 4.5B, which in the world of Japanese car auctions means it’s mint, and there are no modifications in sight behold the Alpina touches. The interior, which is surprisingly restrained for a Japanese Alpina, is in just as tidy a condition as the exterior, the seats seemingly still plump with no visible wear on the bolsters. No surprise given it’s only covered 47k miles, and the asking price of £28,940 seems very reasonable given how rare it is. For instance, this slightly newer D5 BiTurbo isn’t nearly as powerful and is just £4k cheaper. You could always try to grab a nice deal on this B5 that’s currently for auction, but you can bet it’ll go for a good chunk more than this B6. The pair would make a brilliant two-car garage, mind.

Not a car which I have funds or space for, sadly.

For the gentleman or lady who does have both, this is a connoisseur's choice in my opinion. I'd say a deal might be done but the advertised price isn't that silly.

I'd happily have that for high days and holidays.

It's most likely already been said, but I really do think this, Chris Bangle designed, era of 6 Series and the Z4 will become design classics in the future. I really think if they were released today they'd look as progressive as they did back then.

If I had the money I'd certainly be buying this!

Fantastic M6 alternative. I had the V10 M6 around 3 years ago. When on song, the engine was a masterpiece. But, always felt on edge and not that refined. Gearbox was annoying in traffic and clunky. It was a car that came alive only when pushed hard. And it was the thirstiest car I have ever owned.

My old man has an E60 B5, and whilst similar in power to the M5/M6, is a totally different proposition. It's smoother, way more refined, better to live with and drive as a daily. The thrust is savage and relentless, especially after 4k rpm. But, it effortlessly cruises along at motorway speeds.

Alpinas really are the gentleman's alternative to the M cars.

Shame this B6 doesn't have the extended leather option. That adds another level of luxury to these coupes.

Wonderful thing of beauty that was once the ugly duckling of car design. The Alpina effect simply adds to the appeal and I've a soft spot for anything with a blower on it. But does it actually have one? The oracles would suggest the V8 was twin turbo not supercharged.

lol at the above, yes the image sort of fits. Think older Alpinas may start to take off as production is wound down under BMW ownership.

What an amazing car.
I think that would be superb for a cross Europe road trip.

The 6 series are the best built BMW’s. I’m pretty sure it’s not built on a 5 series either.

I used to have an even rarer U.K. e63 B6s. Amazing cars with a powerhouse of an engine. They just pull and pull but always smooth refined. Great supercharger noise too as that radial charger spins up.
This one leaves me a little cold as it’s missing the amazing Lavalina leather option.

Quite a cool car but that wheel design that Alpina played with for a while has never sat right with me. Just doesn’t seem to suit anything.

That's a great looking car with a strong chance of future appreciation. Buy and hold; and drive of course.

Zooming in on the supercharger installation shows how Alpina were certainly tuner cars not factory cars in those days.
It look like the sawed the plastic engine cover diagonally to make space for the air intake pipe, which has been flattened in a couple of places so the bonnet can close. I was expecting a more factory look, not something you could cobble together with a heat gun and a hacksaw.

I'm not overly encumbered with knowledge on this but it does look more like a turbo in the under bonnet pic?

have an old issue of modern classic magazine comparing this to the m6 - the alpina always appealed more to me.

Completely agree thumbup tbh, never liked any of the multi spoke wheel designs.

Thanks very b****y much for show casing that. I am now wondering about swapping in my 2015 D3 Bi Turbo Touring for it. Cheers.

Shouldn't your eyes confirm this in the pictures shown without having to Wiki it?

It's a lovely car.
