2013 BMW Alpina B7 First Drive: More Power Makes It Even More Charming - Car and Driver
The Alpina B7 is also known as a bad-ass 7-series, an adjective-and-noun combo that sounds pretty awesome, too. And the car is just that, thanks to its muscled-up version of BMW’s corporate twin-turbocharged 4. 4-liter V-8 and the Aqua Velva–smooth manner by which it does its work. ) There are aesthetic tweaks to the front and rear ends, but the most notable update involves the fitment of BMW’s Valvetronic variable valve timing and lift to the force-fed V-8, a tweak that brings 40 additional hp and 22 more lb-ft of torque. Horsepower now stands at a stout 540—97 more than in the 750i, which uses this same basic engine, albeit with smaller turbos, different heads, and different pistons—and torque is 538 lb-ft. For further perspective, the B7 even has a few more ponies in the stable than does the twin-turbocharged V-12–powered 760Li. The Alpina’s top speed has increased from 175 to as high as 194 mph. Explore the nether regions of the Alpina B7’s prodigious output, and 0 to 60 ought to be accomplished in 4. 2 seconds, weight and traction limiting improvement to about 0. 1 second versus the 4. 3 we recorded with both rear- and all-wheel-drive... Despite the burly stats, keep in mind that the B7 is not intended to be an M7. Alpina’s. Source: www.caranddriver.com
