I’m still eagerly awaiting for BMW to release how the M-Sport package for the new F10 BMW 5-Series will look like but for those who prefer something a little more aftermarket than just a regular M-Sport package there’s always the Alpina kit, and this is what the Alpina F10 will look like. This first sketch released by Alpina shows the Alpina B5 Bi-Turbo, which will likely be based on the 550i. It will be fully unveiled at the Goodwood Festival of Speed in the UK this year. You can expect Alpina to work similar magic with the 4.4 liter twin-turbo V8 engine as they did in the B7 Bi-Turbo based on the 750i.
In the B7 Bi-Turbo, Alpina managed to extract 500 horsepower and 700Nm, which is up from the engine’s stock 407hp and 600Nm figures, but still less than the M version of the engine found in the X5 M and X6 M which makes 555 horsepower but curiously less torque than the Alpina engine at 680Nm. That M engine can be massaged to make crazy figures as high as 715 horsepower and 845Nm of torque, as Nowack Motors managed to demonstrate earlier this year.
