Report: GM developing twin-turbo 3.0L V6 to combat Ford’s EcoBoost

03/23/2010, 9:15 PMBY MARK KLEIS

According to engineers within General Motors, the automaker is currently far along in developing a new twin-turbocharged 3.0-liter V6 that will help to combat Ford’s EcoBoost offerings which also feature twin-turbochargers. GM has been rumored to have a twin-turbocharged V6 in the works for years, but now it appears they actually may be close to introducing a TT V6 with production intent as this engine has been reportedly assigned a PRO code.

According to a GM Inside News exclusive, several sources within the engineering department at GM confirmed that a twin-turbo V6 is in the latter stages of development.

GMI’s engineering sources have clarified that GM has been developing a 3.0-liter twin-turbo engine, which has even been assigned a PRO code of ‘LF3.’ The assignment of a PRO code lends credibility to the suggestion that this engine will end up under the hood of future GM products. GM’s naturally aspirated, direct-injected 3.0-liter V6 goes by the PRO code of ‘LF1.’

GMI’s sources were unable to provide expected power numbers, but did suggest that they were intending to produce power numbers in the same realm as Ford’s 3.5-liter EcoBoost engine. They also suggested that production could start in late 2011 to early 2012, seeing first duty in the upcoming Cadillac XTS.

Sources also indicated that the TT V6 may end up in the Cadillac ATS and possibly even a future Chevrolet Camaro.

This is honestly pretty exciting. If GM can get to 365 HP out of a 3.0 V6, that's over 120 HP/liter while being almost 15% smaller than the Ford 3.5 Ecoboost engine.

if it has the same hp/L as the LNF it could produce almost 400hp. this would be sweet for hipo malibu or something similar. not sure SS worthy, but maybe.

This is only the start.

The LNF was not even close to what it coil do. The tranny was the limiting factor.

New trannys and duel clutches will only bring more HP torque.

New transmissions and dual clutches indeed, and no more roots-type superchargers(!!!!).

This would be a good engine for Buicks, a future Impala, Lambdas, and lower end Cadillacs. There are a lot of potential applications. Although a 3.6 twin turbo would be nice to see as well. As far as the XTS goes, whatever engine they use doesn't matter much since it is front wheel drive. Had they made it rear drive a 6 liter twin turbo V12 could have been done.

What is interesting, is Mercedes is working on a pressure wave supercharger, and they can get 400 hp form a 3.2 liter V6. The engine combines the benefits of turbo and supercharging, but doesn't have any lag that turbo motors often have. GM may want to look into that also.

Put the Kool Aid down as in the near future V12's are going to be only the thing of the past inall but the most expensive and rare cars.

As for lag it is very minimal in most DI VVT engines as most have such low end torque that only a small bit of lag is left. It is no where like the old days where you had to plan out where you wanted the power to come in.

I would love a 2.8 Turbo option in the Nox.

Maybe Mercedes can ask VW how it's done because they've done the supercharger + turbocharger setup already.

they need to make a stupid name like ecoboost, that makes people think it will improve mileage, but it cant have Eco in it or people will think ford was the first to market a DI Turbo

wait im starting to think that ecoboost is a ripoff of EcoTech

one application rebirth of the Malibu MAX

Detuned to 300 HP to make room for the regal GSnope, just FWD only

Thriftmatic, meh, doesn't really roll of the tongue, sounds like a KIA or Hyundai or a 25 year old Japanese

Jet_____

or ____Jet is cool though

Maybe TurboJet?

"The new 201X Jetfire 3.0 equipped Buick Regal GS4, more miles, (shows the GS going by a gas station), more smiles.(shows the GS blowing the doors off something/ accelerating FAST)"

Thriftmaster

Turbomatic

Jetfire

Jetstar

Nah..those all sound like they are from 50 years ago or more.

They need something that implies green and eco-friendly...like 'powerGreen'..

3.0 iThrust (stolen off Top Gear). A lower case i makes people think it is a green car and turbos do add thrust.

Hmmm...the lowercase 'i' makes it sound like an Apple product. Maybe 'eThrust' w/ e for eco in green letters.
