The recent presentation of the updated for the 2013 model year BMW 7-Series range inevitably led to the facelift of the sportier Alpina B7, which was revealed today in advance of its world premiere at the historic Pebble Beach Concours d’Elegance in August.

In addition to being enhanced with all the styling and technological updates to the 2013 7-Series sedan, the Alpina B7 also benefits from improvements to its powertrain.

The sports limo will continue to be offered in both regular and long wheelbase versions as well as with a choice of rear or all-wheel drive.

The revised 4.4-liter V8 twin-turbocharged engine with direct-injection features 40 additional horsepower and 22 lb-ft more torque for a total of 540-horses and 538 lb-ft respectively. Furthermore, Alpina has swapped the outgoing model’s six-speed sport automatic transmission for a new 8-speed automatic unit.

The car’s top speed increases from 175mph (282km/h) to 194 mph (312km/h) with RWD and 193mph with xDrive, while acceleration drops into the low-mid-4-second range for all variants (4.3-4.4 seconds) compared to 4.5 seconds for the previous RWD model.

BMW says that all variants of the Alpina B7 come with more than 30 new parts that enhance the design and frontal aerodynamics, while new standard features include updated Xenon Adaptive headlights, LED front fog lights, ceramic secondary controls, Automatic Start-Stop, and the Active protection system.

The new car rides on 20-inch Alpina multi-spoke wheels and is finished in the classic Alpina Blue Metallic paint.

Among other options available are full LED Headlights and a new Bang & Olufsen Surround Sound System.

As before, the B7’s body is manufactured in the BMW 7 Series factory in Dingolfing and hand-finished with the remaining components at the Alpina facility in Buchloe, Germany.

Pricing for the B7 in the U.S. will be $127,600 for standard wheelbase model (SWB), $130,600 for the SWB with xDrive, $131,500 for the long wheelbase (LWB) version, and $134,500 for the LWB with xDrive.

First deliveries will take place in the fall.
