The new B3 S reflects the ALPINA ethos of ultra high performance combined with environmental consciousness. The 3 litre straight six now yields an extraordinary 400hp at 6000 rpm and massive torque – 540 Nm at 4500 rpm. In Coupe form this delivers 0-62 in 4.7 seconds and 186 mph, yet economy is improved (29.1 mpg combined) and CO2 emissions lowered to 224 g/km.
The B3S is readily identified by a redesigned front spoiler and a new rear diffuser which encloses the tailpipes, reducing lift and ensuring optimum engine cooling. The ALPINA Classic alloy wheels get the new design treatment seen on the latest B7.
With switchable six-speed automatic transmission in Saloon, Touring, Coupe and Convertible forms, the B3 S stays faithful to another ALPINA manufacturing edict – that the sporting nature of its cars should not compromise luxury, comfort and everyday usability.
So what does the B S stand for on this 'green machine'?
It's hard to see why you would buy this over an M3. Why have a V6 when you can have a V8?
