Ford Motor Company’s recent introduction of their twin-turbo 3.5L V6 has brought the industry limelight to high tech, forced induction V6 powertrains. Rumors of General Motors joining in on the turbocharged V6 arena have been around for several years now, however GMI has confirmed that The General really will be joining Ford in the high tech turbo bandwagon.

According to GM engineering sources, GM is currently working on a twin-turbo 3.0L V6. Development on the new engine is so far along that it has a PRO code of “LF3.” The naturally aspirated 3.0L debuted in several 2010 products with direct injection and has the code “LF1.”

GMI was not able to obtain projected power ratings on the new engine, however output is very application specific under new SAE testing rules. Sources did say to expect the engine to rival Ford’s EcoBoost 3.5L.

The engine’s introduction is expected in late 2011 or early 2012 in the Cadillac XTS. Sources also state that GM is looking to use the engine in the Cadillac ATS and possibly even the next Chevrolet Camaro. Cadillac has historically always debuted new variants of the High-Feature V6 lineup, so it comes as no surprise that the XTS is the likely to pioneer the 3.0L twin-turbo.

Most rumors surrounding the potential of a turbocharged V6 out of GM have centered on the company’s 3.6L V6. A couple of years ago GMI was told that GM had twin-turbo 3.6L V6’s in development that were generating as much as 435 horsepower. Information regarding the potential of a blown 3.6L silenced for years until GM showed a 3.6L twin-turbo V6-powered Camaro show car at the 2009 SEMA show. The Camaro show car was generating 425 horsepower

 

So, where would this plant be slotted in the 6th gen line up? SS?

 

They could make it an RS package.

I think this would be great for Caddy. Especially for the SRX. It needs more umpf.

 

A 335-fighter ATS sounds good to me.

 

It would surprise me if the RS package would include a specific power plant in the future. I think it will continue to be an appearance package.

This engine will be supplanting V8s. I still think a V8 will be offered in the 6th gen (Z28), but the mid level V8's days may be numbered.

 

Nicely done. That sounds fun.

 

Trucks aside , mid level v8's have been gone from GM cars for years .

Nice hear this unicorn really does have life outside of concepts .

 

This would be great for the SRX and XTS. Hell, it would be good in any vehicle. Probably 350HP in FWD/AWD applications.

 

Fwiw , this engine will more likely than not put the older Saab/Opel 2.8T in the coffin .

 

I wouldn't be shocked if this will power the 6th gen SS.

I think whats happening right now is that Ford, GM, and Chrysler are all waiting to see who will be the first to use a turbo six in their respective pony cars and more importantly, will it be embraced by the consumers. CAFE could dictate how this will be used. Until they can get the V8 to produce higher MPGs at least.

 

Well, it certainly won't replace the V8 in Camaro's lineup, but it might be in addition. My guess is that they wouldn't call the turbo 6 "SS".

I say put one in the Regal GS concept and call it Grand National.

 

Yup, I think it's safe to say that the 2.8T days are numbered.

 

Ford definitely has a faction which wants a turbo V6 in the Mustang. They also have a powerful V8 mafia working against it.

 

Turbo 6 = SS
V8 = Z28

I could see that. Especially if they can get 30mpg out of that engine and gas is over $4 at the time.

 

That's what I'm thinking too. Still offer the V8 for the purists, but the mainstream performance would be the TTV6.
