The bad news for the Alpina B7, of course, is that rival Mercedes-Benz has just updated the engine in its high-performance $138,000 S63 AMG. Gone is the naturally-aspirated 507-horsepower 6.3-liter V8. In its place is a new twin-turbocharged 5.5-liter V8, rated at 536 horsepower and 590 pound-feet of torque (opt for the $7,300 Performance Package, and those numbers soar to 563 horsepower and 664 pound-feet of torque). When it comes to powerplants, the new S63 AMG engine is about as good as they come, but the S-Class' overall performance package still falls short of the B7. Put another way, nobody races an S63, but more than a handful of Alpina owners frequent the track – with hardly a laugh from the peanut gallery.
