They were ahead of the game back then, they would out run Mustangs, Camaro's and even Corvette's, but they are low tech in this day of modern engines.
The EcoBoost engine has 11 to 1 compression with twin turbo's and runs on 87 octane fuel, the variable cam timing for both intake and exhaust cams, and direct injection make it all possible, There is nothing on it that hasn't been done before other then putting it in a reliable package and a 1\2 ton pickup truck. In the past that technology was used in high end German vehicles only.
Gm has the 3.6 engine they use in a bunch of their vehicles, They have had some issues with it but will get it panned out, I would bet you will see that engine in the all new Silverado in a similar package as the EcoBoost but they will generate slightly better numbers, Bring it on! Competition brings us consumers better products.
