The BMW 7-Series range is being expanded for 2017 with two performance-oriented models.

One is the V-12-powered M760i xDrive, which BMW has priced from $154,795. The other is the V-8-powered Alpina B7 xDrive, which has been priced from $137,995. (Both figures include a $995 destination charge.)

Curiously, both cars feature a similar output despite their very different powertrains. The M760i is equipped with a twin-turbocharged 6.0-liter V-12 and delivers a peak output of 601 horsepower and 590 pound-feet of torque.

It’s not quite a dedicated M car but it is the first 7-Series to receive BMW’s tamer M Performance treatment. It’s certainly no slouch as the big but—relatively—light sedan will rocket to 60 mph from rest in just 3.7 seconds. The top speed is limited to 155 mph.

The Alpina B7, on the other hand, makes do with a twin-turbocharged 4.4-liter V-8. It has the same output as the M760i but thanks to the lighter weight of its engine can hit 60 mph 0.1 of a second quicker, requiring just 3.6 seconds to achieve the feat.  Top speed for this model is 193 mph.

In our book, the Alpina B7 is the way to go. Not only does it offer more bang for your buck, but it also benefits from a few styling tweaks exclusive to Alpina. The semi-official BMW tuner has also added its own chassis and transmission calibrations to give the car a distinct feel.

Both cars will be on display this week at the 2016 Los Angeles auto show, which starts Wednesday. BMW will also use the show to highlight its plug-in hybrid portfolio with the display of plug-in versions of the 3-Series, 7-Series and X5, as well as the i8 sports car.
