Gallery: GM’s Next-Gen Engine Boosts Fuel Efficiency by 15%

 

There’s little good news coming out of the American auto industry these days, but here and there we’re seeing glimmers of hope from major car manufacturers. GM has announced that it is developing a more efficient combustion engine that is designed to improve the performance of its vehicles by almost 15%.

    Good job GM, NOT! Look at VW’s diesel and get back to us when you’re operating in this century! Not that VW is anything to praise for being eco-friendly but at least they’re trying. This GM thing is cop-out!

    Isn’t this basically a diesel engine? I guess the key issue is that they have applied diesel technology at higher pressures so that it works with gasoline.
