Alpina B5 F10 will sport 507 PS (373 kW) and 700 Nm of torque from a V8 engine. Also included is an aerodynamic package and 20-inch Alpina wheels.

BMW Aplina has released details on its B5 F10 Bi-Turbo, based on the BMW 5-Series.

Full details are available in the extensive press release, but we can cover the main points here.

First off is the 4.4-liter V8 under the hood which produces 507 PS (373 kW) and 700 Nm of torque. The engine is optimized by way of tinkering with the indirect intercooling system, among others. It's coupled to the SWITCH-TRONIC 8-speed sport automatic transmission from ZF for a fuel economy rating of 10.8 liters/100 km.

Performance figures are 4.7 seconds for the 0 to 100 km/h sprint (62 mph) and top speed is 307 km/h (191 mph). Help to make that sprint as sprightly and enjoyable as possible also comes from a "neutral" suspension set-up which includes shorter but progressive springs and specialized suspension arms. An electronically-adjustable system is also available (Variable Damper Control) in four settings - Normal, Comfort, Sport and Sport+.

For the B5 to roll on are 20-inch Alpina wheels wrapped in 255/35ZR20 tires at the front and 285/30ZR20 for the rear.

A full aerodynamic package includes Alpina branded front fascia, side skirts, rear bumper with an integrated quad-exhaust and optional diffuser.

On the inside are a leather finish with electronic goodies such as gauges in a black panel LCD display from Alpina.

No price details have yet been made available.
