Want the fastest production wagon in world? Alpina has the answer for you with its new B5 Bi-Turbo Touring's 322km/h top speed.

As an alternative to BMW's M range of vehicles, Alpina has always offered models with similar performance but combines it with greater comfort. And despite us saying comfort, rest be assured that there is still plenty of performance on offer thanks to the Touring's twin-turbo 4.4-litre V8 engine that pushes out 608bhp and is paired to an eight-speed automatic transmission.

Similar to the M5, power is sent to all four wheels and the Alpina is capable of sending up to 90 per cent of torque to the rear wheels if needed. This enables the car to sprint to 100 km/h in 3.5 seconds and onwards to its 322km/h top speed, also allowing it to go past the Porsche 911 GT3 RS and Mercedes-Benz AMG GT R as shown in the cheeky video.
