Except for the SRT version, the 2014 Jeep Grand Cherokee comes standard with a 3.6-liter V6 that produces 290 horsepower and 260 pound-feet of torque. This is the only engine you can get on the Laredo, but two other engines are available on the Limited, Overland and Summit models: a 5.7-liter V8 rated at 360 hp and 390 lb-ft of torque and a turbocharged 3.0-liter diesel V6 that cranks out 240 hp and 420 lb-ft of torque.

The SRT comes exclusively with a 6.4-liter V8 that produces 470 hp and 465 lb-ft of torque.

All 2014 Grand Cherokees use an eight-speed automatic transmission. The Grand Cherokee SRT uses a heavier-duty eight-speed built to handle its more powerful engine. The SRT also features a specialized all-wheel-drive system tuned more for high-performance driving than off-road use.

The standard 3.6-liter V6 gets an estimated fuel economy of 17 mpg city/24 mpg highway and 19 combined mpg when equipped with four-wheel drive and 17/25/20 with rear-wheel drive (2WD). At the test track, a Grand Cherokee Overland V6 with 4WD sprinted from zero to 60 mph in a fairly quick 7.9 seconds. When properly equipped, maximum towing capacity for a V6 Grand Cherokee is 6,200 pounds in the 2WD and 4WD configurations.

The optional 5.7-liter V8 gets an estimated 14/20/16 mpg when equipped with 4WD and 14/22/17 with 2WD. Towing capacity for the 5.7-liter V8 Grand Cherokee is 7,200 pounds with 4WD and 7,400 pounds with rear-drive. Fuel economy is vastly improved when you select the new diesel engine, which is said to achieve 21 mpg city/28 mpg highway when paired with four-wheel drive and 30 mpg highway with rear-wheel drive. When equipped properly, tow capacity is the same as the V8.

The SRT V8 returns an estimated 13/19/15 mpg, a slight improvement on last year.

Non-SRT Grand Cherokees come with three available 4WD systems: the single-speed, light-duty Quadra-Trac I system (standard on the Laredo), Quadra-Trac II with a two-speed transfer case (optional on the Laredo, standard on Limited and Overland), and Quadra-Drive II with a rear electronic limited-slip differentia l (optional on Limited and Overland, standard on Summit). An adaptive air suspension (Quadra-Lift) and a driver-selectable traction control system that adjusts to different surfaces are also available (optional on the Limited, standard on 4WD Overland and Summit).
