ALPINA has launched the brand-new B5 Bi-Turbo Touring, a supercharged BMW 5 Series, which is the fastest production estate car on sale. Prior to the ALPINA B5 Biturbo Touring, the Mercedes-AMG E63 S Estate was the fastest production wagon.
While the B5 Touring has retained the basic proportions of the original BMW 5 Series Touring, subtle changes have been made to the bodywork. The car has a new front bumper, multi-spoke wheels and quad-exhaust outlets at the rear end.
ALPINA’s refinements continue inside the cabin, with Nappa leather throughout and blue ambient lights. There’s also a range of customizable trim colors and wood finishes for those looking for a more personalized cabin.
Buyers have two exterior colors to choose from, ALPINA Blue and ALPINA Green, along with the full range of paint options offered by BMW.
The ALPINA B5 Biturbo uses a revised version of the same 4.4 liter twin-turbocharged V8 that you’ll find in the BMW M550i. Except it gets new turbochargers, a new intake, new pistons, revised cooling and an ECU tune, among many other things, so it makes 600 hp and 590 lb-ft of torque. That’s the same horsepower figure as the all-new BMW M5 but the ALPINA packs more torque. All of that power is sent through an eight-speed automatic, that’s also been revised by ALPINA, to all four wheels.
According to ALPINA, the B5 Biturbo Touring can top out at 201 mph. For comparison’s sake, the Ferrari 458 Italia topped out at 202 mph.
