Excerpt from http://www.automobilemag.com/reviews...9_2014_bmw_x5/:

The twin-turbo 4.4-liter V-8 makes 445 hp and 480 lb-ft of torque, while the twin-turbo 3.0-liter inline-6 makes 300 hp and 300 lb-ft of torque. Then you can get the six-cylinder engine in the customary all-wheel-drive X5 xDrive35i or in the new, rear-wheel-drive sDrive35i. Plus there's a twin-turbo 3.0-liter inline-6 diesel expected in the spring, which will make 255 hp and 413-lb-ft of torque. We found the personality of the V-8 engine to be somewhat stolid, while the diesel proved livelier, yet the eight-speed automatic really proved to be the dominant player in the powertrain.
