Rather than an all-new car--it's based on the standard 7-Series, after all--the 2013 model gets a set of updates. The improvements include an additional 40 horsepower (now to 540 hp) and 22 pound-feet of torque (now 538 lb-ft) via addition of Valvetronic throttle-less intake and other tweaks. The extra power raises top speed to 194 mph (the drag-limited max of the car, though the xDrive all-wheel drive model runs out at 193 mph). An eight-speed automatic transmission is standard. The 2013 Alpina B7 is available in standard wheelbase or long-wheelbase, with either rear- or all-wheel drive.
All models will reach 60 mph in 4.3 to 4.4 seconds--very, very quick for such a large car.
Other new elements include a total of 30 new parts in the design and aerodynamics departments: new kidney grilles, updated Xenon adaptive lights and LED fog lights, revised tail lights. Optional upgrades to the standard B7 kit include full LED headlights, Bang & Olufsen surround sound, and a wide range of exterior colors and interior materials.
But what about that price? The standard short-wheelbase, rear-drive B7 starts out at $127,600. Add $3,000 for xDrive. The long-wheelbase model starts at $131,500, and again jumps $3,000 for xDrive. The B7 is only available by special order, and production capacity is limited.
So should you make the jump from a normal 7-Series? If you're into very fast executive limos, perhaps. We'll throw the entry-level six-cylinder 740i right out, since anyone considering the B7 wants power, but the B7 still equates to a $43,000 premium over the 750i. That rather healthy stack of cash buys you another 140 horsepower, sure, and some exclusivity and style, but that's a price increase of more than 50 percent. The math is almost the same for the long-wheelbase version.
If you're eyeing the magnificent turbo V-12 760Li, however, the price is right on par with the Alpina: $137,300 to start. But instead of a hotted-up V-8 model, you have a regal V-12 under the hood, and just about the same horsepower (535 for the V-12 vs. 540 for the Alpina V-8). For our money, it would probably be the 760Li, but we can understand why you'd opt for the Alpina.
