The Yukon is a large affordable SUV, which is produced and sold by General Motors. The Yukon is very similar to the Chevrolet Tahoe, which is also sold and manufactured by General Motors.
The full size SUV comes with various trim levels and a few different engine options. The first option for the Yukon, which comes standard with the SLE and SLT trims, is a 4.8 liter eight cylinder engine. This choice gets about 295 horsepower and 305 pound feet of torque. It is widely perceived that the smallest engine option is not sufficient for many drivers.
The next available engine, which comes standard with the 2010 XL, is a 5.3 liter eight cylinder. The Vortec 5300 V8 engine produces 320 horsepower and 340 pound feet of torque.
The last option for the 2010 series is a 6.2 liter eight cylinder engine. This Vortec 6200 V8 engine comes standard in the 2010 Denali and produces 403 horsepower and 417 pound feet of torque.
To help with fuel efficiency, General Motors installed an Active Fuel Management system which shuts off four of the eight engine cylinders when they are not needed (such as when the driver is cruising or idling). This has helped with fuel efficiency as the base model can now get 22 miles per gallon on the highway, compared to last year's model which got only 19.
The SLE and SLT trim levels come standard with two wheel drive, but can be upgraded to all wheel drive. The XL and Yukon trim levels come standard with all wheel drive. Another improvement over previous year's models is the introduction of a six speed automatic transmission. This transmission is an upgrade over last year's four speed transmission.
