Alpina B6:

The Alpina B6 is the second generation of the high performance grand tourer manufactured by German automobile manufacturer Alpina from 2005 to 2010. Based on the BMW 6 Series , the car was available in coupé and convertible bodystyles. The B6 was introduced in 2005.
The B6 is based on the 650i and uses a modified version of its 4. 4-litre N62 V8 engine, designated by Alpina as the H1. Changes to the engine include an Alpina specific block made by Steyr, a forged crankshaft and low compression Mahle pistons. The engine retains BMW's VANOS system and uses a centrifugal-type supercharger, made by ASA to Alpina's specifications and a stainless steel Akrapovic exhaust system with quad exhaust tips. These modifications allow the engine to generate 500 PS at 5,500 rpm and 700 N⋅m of torque at 4,250 rpm. The choice of the forced induction V8 engine over the naturally aspirated V10 engine of the M6 grants the B6 better fuel economy figures....(Read more on Wikipedia)
