The rival of the BMW M5 of Alpina revealed

This is Alpina's new B5 Biturbo, which makes its public debut at the Goodwood's Moving Motor Show.

The B5 uses an optimized version of BMW's 4.4 liter bi-turbocharged V8 engine, which produces 500 hp and 516 lb-ft of torque. That's enough, says Alpina, for a time of 4.7 s and a top speed of 191 km / h.

Alpina often avoids using the same powertrains as the M-division models, but with a few differences in the intake system, the B5 will face the next choice of M5 engine. Its transmission will be totally different, however; the B5 uses a modified version of the ZF's eight-speed automatic transmission, while the M5 is widely invited to use a dual-clutch unit.

Alpina says the B5 offers first clbad fuel economy and CO2 emissions at 26.1 mpg (combined) and 252 g / km, respectively.

No prices for the car have been announced, but British buyers should expect to pay around £ 70,000 for the car. The first deliveries are expected in the autumn.
