Alpina Releases 600-Horsepower B5 Biturbo

Alpina is no stranger to fast Bimmers, and there is no end to the insanity in sight. Today, the famed BMW tuner has released a new B5 Biturbo that makes even the mighty M5 look like a kid’s toy.

Okay, maybe it doesn’t make the big M sedan look like a child’s toy, but it does best its most powerful variant, the Competition Package-equipped M5, by an impressive 25 horsepower. What’s more, it has a whopping 90 pound-feet on the 500 pound-feet the base M5’s 4.4-liter V-8 engine puts out.

All 600 horses and 590 pound-feet of torque travel through an eight-speed auto transmission with Alpina Switch-Tronic out to a limited-slip rear differential. This delivers a 4.2-second sprint to 100 km/h (62 mph) and a top speed of 328 km/h (204 mph), which is 0.2 seconds quicker and 14 mph faster than the base M5.

On top of the go-fast bits, Alpina also turned up the heat on the chassis. Under the skin, there are electronically adjustable dampers and active roll stabilization. On the corners, you’ll find 20-inch Alpina Classic rollers wrapped up in Michelin tires to keep the sedan or wagon version of the B5 glued to the road.

Inside the B5’s cabin, Alpina decked out this modified Bimmer nicely. It includes leather upholstery, Comfort seats, navigation, Bluetooth, Piano Lacquer trim, a hand-stitched Lavalina leather-wrapped steering wheel, and available burled Myrtle wood trim.

On the outside, the typical Alpina touches are present, including the two double-end exhaust exits, a modified diffuser, and front and rear spoilers for added downforce.

There are no pricing details available yet, but you can rest assured that the Alpina B5 Biturbo will be super-expensive. Also, there is no mention of this model making it to the U.S., so chances are, we’ll never see it here.
