It's amazing that our cars have a lateral acceleration of .98g. BMW wins in braking, acceleration, and cornering. Yet, it's $60k cheaper than a Porsche Cayenne Turbo S with similar options.
By the way, the new X5M and X6M actually makes 647HP at the crank with 93 octane (not 567HP). BMW was able to legally sandbag the HP numbers by testing with lower octane fuel.
