G-Wagon Engines: the V8 AMG G63 vs. the V12 AMG G65

 most basic choice for an AMG G-Class buyer is engine. Both are potent, sophisticated, and powerful, but one comes with extra power and a higher price tag.

The AMG G63 comes with a 4.0-liter twin-turbocharged V8 with 577 horsepower. The AMG G65, meanwhile, comes with a 6.0-liter twin-turbocharged V12 rated at 630 horsepower. Both are more than powerful enough to push this 5700-pound SUV along, and with ample ground clearance, full-time four-wheel drive, a two-speed transfer case, and three locking differentials, these vehicles are just as impressive off the road as they are on it.
