Well, this is not an M3, but it's faster and packs around the same power as the current M3, and does have a straight-six engine. Meet the new Alpina B3 Biturbo: primped, primed and ready for the Geneva Motor Show.
We'll get full details next week, but the salient details are encouraging. Alpina has taken the award-winning 3.0-litre six from the 335i, added in another turbo to make it a twin, and upped the power from 302bhp to 410bhp and 442lb ft of torque.
There's no six-speed manual on offer, only an eight-speed automatic, which somehow marshals those 410 horses to accelerate from 0-62mph in 4.2 seconds, and on to a top speed of 190mph. This is important, because the current, V8 M3 hits 62mph in 4.8 seconds and hits a limited top speed of 155mph. See? Faster.
Apparently, it also returns some 40.9mpg (though good luck achieving that with 410bhp at your disposal), while emissions sit at 177g/km of CO2. Compare that to the M3 Coupe's 290g/km and 22.8mpg combined average, and you find progress, dear reader.
Of course, the M3 is a proper M-Division product, honed and developed for one purpose, and is definitely not a tarted up 335i. We'll have to drive the new B3 to decide if it can match the M3's mighty depth of talent...
For now though, what does the Internet think of the new B3 Biturbo? Are you lot fans of Alpina making stupidly fast cars, or do you prefer the proper M versions?
