For reference, the BMW X5 xDrive35d with this same engine produces 265 horsepower and 425 pound-feet of torque. The all-wheel-drive X5 crossover is able to achieve up to 26 miles per gallon when equipped with the 3.0-liter diesel engine. The 7 Series is indeed a big boy, but we expect it to achieve better fuel economy numbers than the X5.
Car and Driver says that the diesel 7 Series should arrive in about one year's time, where it will compete against the Mercedes-Benz S350 Bluetec and Audi A8 3.0 TDI for diesel-powered luxury supremacy. The rest of the updated 2013 7 Series range goes on sale this summer.
