Alpina, the BMW tuning specialists, has released and revealed the 2012 Alpina BMW B3 GT3 E92 at the 2011 Tokyo Motor Show. This model will be a special production run limited to just 99 units.

The B3 GT3’s B3 S Bi-turbo motor is good for 408hp and 398 lb-ft torque. It’s paired with an Akrapovic titanium rear silencer. All this propels the B3 GT3 from 0-62mph in just 4.6 seconds.

Unexpected debuts have been rare so far at the 2010 Geneva Motor Show, but one car which we didnt expect to see was a new Alpina B3 based on the LCI (facelifted) E92 coupe. Power has been bumped up to 400hp / 397lb-ft tq and the car has been fitted with some beautiful aero parts and a stunning interior. Check out the B3 S and the other Alpinas present inside.
