1. 2017 BMW Alpina B7 xDrive

the Alpina B7 stands at the top of the 7-series lineup, at least until BMW’s own M760i appears. But the Alpina offers a distinctly different character: The M760i will be powered by an updated version of BMW's twin-turbocharged V-12, while the B7 employs a twin-turbo V-8. Alpina says the B7 accelerates to 60 mph in 3.6 seconds, which may be as conservative as the original top-speed forecast; a 2013 Alpina B7 we tested with a mere 560 horsepower ran to 60 mph in 3.8 seconds, and we expect the new model to be about 200 pounds lighter.
