Alpina unveils B4 Bi-Turbo at Tokyo Motor Show

Thu, 21 Nov 2013

It didn't take long for German tuning house Alpina to debut its version of the new BMW 4-series, and they've chosen the Tokyo Motor Show to unveil the new model. Under the hood of the Alpina B4 Bi-Turbo is a 3.0-liter straight-six engine with two turbochargers, making 410 hp and 442 lb-ft of torque. Alpina has tweaked the suspension a bit as well, installing their adaptive-sport suspension and an eight-speed automatic transmission. A high-performance braking system has also been added, with 14.5-inch discs up front and 13.5-inch discs in the rear.

On the outside, the BMW 4-series coupe has received a functional aerodynamics package consisting of redesigned bumpers, front and rear spoilers, and 20-inch Alpina wheels wearing Michelin Pilot Sport tires. On the inside, the seats feature Lavalina leather upholstery, as well as Alpina badging.

Alpina says the B4 Biturbo can exceed 180 mph.

Alpina says that the sprint from 0-60 mph in the B4 Bi-Turbo now takes 4.2 seconds, with the coupe being able to reach speeds in excess of 186 mph. As far as fuel-efficiency figures go, drivers can expect 7.6 L/100km, which translates to a very impressive 30.9 mpg U.S. Not bad for something that produces north of 400 hp.

The Alpina B4 Bi-Turbo is expected to go on sale in May of next year, though we're unlikely to see this model in the U.S. anytime soon.
