The Cadillac Escalade debuted in the 1999 model year and -- just a few years later -- General Motors saw the need to expand its luxury SUV lineup. With this expansion came the 2002 debut of the Cadillac Escalade EXT, a full size luxury SUV with a truck bed based on the Chevrolet Avalanche.
Coming into the 2013 model year, the Escalade EXT is unchanged from 2012. It gives customers three trim-level choices, which include Base, Luxury and Premium. All three trims come standard with a 6.2-liter V8 engine that produces 403 horsepower and 417 pound-feet of torque, and delivers power to all four wheels via a six-speed automatic transmission. This setup nets the Escalade EXT a seven-second sprint to 60 mph and ratings of 13 mpg city and 18 mpg highway.
