The base engine is a four-cylinder 2.4L making 182 horsepower and 172 lbs.-ft. of torque. But if you need the maximum towing capacity of 1588 kg, tick the 301-hp and 272 lbs.-ft. of torque V6 box on the options sheet. The six-speed is the only automatic for either front-wheel drive or optional all-wheel drive.
