2013 GMC Sierra 1500
Despite sporting some outdated styling, the GMC Sierra 1500 is essentially the same as the Silverado 1500 – it all comes down to which vehicle’s styling you like more. Little has been added to the Sierra 1500 for the 2013 model year, since a refresh is due soon. Four different engines are available: 4.3-liter V6, 4.8-liter V8, 5.3-liter V8, and 6.2-liter V8. The 4.8-liter comes standard with an aged four-speed automatic, while all other powerplants are mated to a six-speed automatic transmission.
