Like a big brother to the B3, the B8 is very unique because of its V8 engine. Based on the 4.4L from the 540i, it puts out 333 horsepower, 93 and 68 more horsepower than the
BMW M3 and Alpina B3, respectively. 350 of its 470nm of torque are available at 1000rpm. Over 40 modifications to the engine compartment had to be made before the V8 fit in. Only 231 cars were built in its three year lifespan from 1995 to 1998 however 4 more detuned versions with a 4.0L engine and 313hp were also built and sold exclusively in Japan.To achieve the bump in power and displacement over the stock engine, new engine blocks were cast by
BMW for Alpina, higher compression Mahle pistons were added, the valve timing was changed, and a new exhaust system and new catalysts were fitted. A six-speed manual tranny made by Getrag is the only transmission available. Exterior differences include a new front spoiler, an optional rear spoiler, optional Alpina decals and 17in Alpina wheels. Given the huge increase in power it is very surprising to see the Alpina accelerate slower than a stock
M3, but a conservative estimate may be to blame. If your main concern, however, is showing off your V8 3-series than the B8 4.6 is the car for you. - by Traian Popescu
