Detroit LIVE: GMC Sierra and Chevrolet Silverado image

General Motors has brought the new generations of the GMC Sierra and Chevrolet Silverado to the 2013 North American International Auto Show (NAIAS) in Detroit.

After pulling the wraps off the 2014 GMC Sierra and the 2014 Chevrolet Silverado in late 2012, the two popular models are being placed into the spotlights once again, this time with the North American based automotive giant bringing them to the 2013 Detroit Motor Show. General Motors says that the new generation of the GMC Sierra, which is wearing the 2014 model year in its name, is coming with three new engines, a 4.3 liter V6, a 5.3 liter V8 and a 6.2 liter V8, all of them EcoTec3 and offering improved fuel efficiency, more torque and more power.

The same engines mentioned above are being used on the new generation of the Chevrolet Silverado too, in the same configuration. GM says that each engine will get direct injection, Active Fuel Management and continuously variable valve timing (CVVT) and direct injection, which should play a main role in their fuel efficiency. Unfortunately General Motors is still keeping all the other details a secret for the moment and more on the two popular models will probably be known close to their launch, which is scheduled for later on this year.
