2010 NAIAS: New Heavy Duty Gas Engine Could Be Quickly Produced, GM Vice Chairman Says

In November, we reported word from our sources that GM is working on a large displacement (about 7 liters) direct injection gasoline engine for its workhorse Heavy Duty pickup trucks as an alternative to pricey diesel engines. It would also compete against new engines from Ford and Chrysler. Ford will start selling its new 6.2-liter V-8 for the Super Duty in the spring, and Ram trucks will have a new 6.4-liter gas V-8 by 2012.

At the North American International Auto Show in Detroit, we had a brief conversation with Tom Stephens, GM’s vice chairman in charge of global product operations. Before his current position, Stephens was executive vice president of GM global powertrain.

“I think our current 6.0-liter V-8 is a good engine,” Stephens said. “We used to have an 8.1-liter V-8, but its take rate was low so we discontinued it [after 2006]. If there’s a business case for a more powerful gas engine (than the 6.0-liter) in our heavy-duty pickups, we could do that very quickly.”

Thanks for that piece if information!

Make it more fuel efficient that the current emission stangled diesels and it would sell.

i thing gm is a company,Abel to build new engine faster ,compare to ford and dodge,whit better fuel,more torque and horsepower,they have a better knowledge on engine.especially from the front to the back of the truck,good balance.

GM should retire - entirely. Lack of steps in the path of efficiency and quality. It's the same bull different day. V8's... is that all american's want? No.

GM, step it up.
Break out the 1/2 ton diesel's. Make a diesel hybrid. Do something. I'm disgusted and tired of seeing the same bull on the road everyday.

i agree with jay ..there is a reason they went bankrupt and ford didn't.

Wait, you mean because Ford mortgaged everything before the credit markets froze up and because GM was doing better at the time they didn't need the loans, and when they finally did, they weren't able to get them because no one was lending? So because Ford needed help first, and were able to secure loans that GM couldn't because of forces completely out of their control, Ford is better? Good call on that one /sarcasm.

@Tim - GM was in trouble long before the credit markets froze but keep thinking that if it makes you feel better.

so, is this how GM and DODGE will compete against the
ECO-JOKE?

it isnt even ford's idea. they just gave it a name !...bull!!

GO GM!!!!

GO RAM!!

GM is bringing back the 7.4 454??????

That's just what I want, a big new gas motor, in a Chevy truck.
