Alpina is an interesting BMW tuner, taking run-of-the-mill BMWs and transforming them directly on the BMW assembly line. In some markets, like here in Southern California, you can walk into your local BMW dealership and see a (grossly inflated) Alpina vehicle on the showroom floor. The company’s resume extends from 3-Series E21 to E90, 5-Series E12 to E60/61, 6-Series E24 to E63/64, 7-Series E32 to E65/66, and even the 8-Series E31. Oh yeah, they like to dabble with the Z1, Z4 and Z8 roadsters too.

Now naturally since Alpina sells full automobiles rather than just tuning packages, their end product better be impressive. They claim the new B3 S sports 400-hp and 400 ft-lbs of torque, a 33.33-percent increase from the factory 300/300 figures. They don’t really elaborate on how these figures are achieved, but if we had to guess it’s pretty simple through an ECU upgrade that tosses in (safely of course) more boost and fuel to the 3.0L inline-six twin-turbo. Oh, and apparently the increased horsepower and torque comes with a side-effect of lowered emissions. We’re pretty sure that’s just negated though since you’ll just be more tempted to romp on the throttle.

On the exterior is a front spoiler and a new rear diffuser, both sporting very traditional Alpina styling. Their Classic alloy wheel gets a new treatment as seen on their previously released B7.

Currently the offering is only available in the U.K. and this isn’t just available for the coupes and convertibles, they’ve got a similar package for the E90 sedan.

Official press release available after the break.

New Alpina B3S boasts 400 hp and reduced emissions (UK)

Following its recent world debut at the Geneva Motor Show, the new ALPINA B3 S Bi-Turbo is now available in the UK. Higher levels of output and efficiency make the model’s unique edge in this rarefied market sector even sharper.

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 CO2emissions 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.

First deliveries of the B3 S Bi-Turbo start in July with availability through Sytner, UK concessionaires for ALPINA.
