The XT4 represents one of the important new vehicles from GM's luxury brand in almost a decade. With rivals like the X3, Q5 and GLC, has its work cut out for it, if it hopes to stand out from the crowd. Early reports suggest we could see a 2.0 liter turbocharged engine, that will deliver around 237hp and 258lb-ft of torque. Cadillac has promised 30mpg on the highway and city and combined fuel economy ratings are expected around 25 and 27mpg. A 9 speed automatic transmission should help it deliver these figures, and cylinder deactivation and start/stop are likely to be present.
