This big SUV is able to transport a lot of people and their gear, as well as a heavy load. It's still offered in regular and extended versions, the latter of which is the equivalent of the Chevrolet Suburban. In terms of mechanics, the Yukon shares its independent chassis with the Sierra pickup. This year, a new 8-speed automatic gearbox is partnered with the 6.2-litre V8 engine. The Denali versions are the most luxurious.
