    SRX, Lambdas To Gain New Twin-Turbo V6

    SRX, Lambdas To Gain New Twin-Turbo V6
    SRX will gain twin-turbo and hybrid power.
    www.gminsidenews.com
    August 13, 2010
    By: Nick Saporito


    NOTE: 2010 3.0L V6 ("LF1") pictured above.

    Back in March GMInsidenews uncovered General Motors’ plan to produce a twin-turbocharged variant of its 3.0-liter V6. At the time of publication the engine was far enough in development to have its own RPO code—LF3. Sources, however, were not 100-percent sure on which applications the new turbo mill would end up in. Over the course of the past five months GM has apparently firmed up at least two product lines that will utilize the LF3.

    According to two different sources the twin-turbo 3.0-liter will find its way into the Cadillac SRX luxury crossover and the next-generation Lambda full-size crossovers. The SRX will gain the new mill for the 2013 model-year, which is likely to bring a mid-cycle enhancement to the crossover as well.

    Today the SRX is powered by the naturally aspirated 3.0-liter V6 and optional 2.8-liter turbo. GM will be dropping the 2.8-liter in favor of the new twin-turbo, but we’re told the 3.0-liter base engine will likely be dropped in favor of the 3.6-liter V6. GMI has been told that a Two Mode hybrid variant of the SRX is also slated. Like the short-lived Two Mode Saturn Vue, the SRX is said to have a plug-in option as well.

    It is already on the record that the 2013 model year will bring new Lambda crossovers, including the Buick Enclave and GMC Acadia. The redesigned crossovers will see a displacement downsizing in favor of the twin turbochargers on the LF3. At this time GMI has not been informed of any additional engine offerings on the new Lambda’s, though it is expected that the twin-turbo will be optional on the lower end models.

    Additionally, sources have stated that the LF3 will end up in the upcoming Cadillac XTS and next-generation Chevrolet Impala. No power or fuel economy figures are known at this time.

    Sweet!!!!!!!!!!!!!!!!!!!!!!!!

    Nice to have it confirmed. With the Ford 3.5 to 3.5 turbo, fuel economy stayed pretty close and power and low end torque went way up. With the 3.0, I'm hoping GM can offer two different trims: one that has performance on par with the 3.6 with better fuel economy, and one that can toe off against the Ecoboost head to head for economy and acceleration.

    although this is great news, I agree w/ you Extreme, their forecasting is a bit off/delayed. FOrd just introduced their TTv6 and it is being implemented in its F150 w/i the next model year. Again, I like the idea, just wish their thinking caps were on sooner!!

    If Ford is getting 365 out of its 3.6L, let's say it's a safe bet Gm's going to pull around 300 out of a 3.0. Fair enough?

    Considering how poor the fuel economy of the NA 3.0 is, I hope GM knows something that we don't.

    Hence... the Twin Turbos... that should make up the poor fuel economy that you're referring to... but, time will only tell...

    In the sea of new automotive faces,
    there's nothing like the appreciation and beauty of an older model. Let's represent!

    Cool...it would be hilarious if they put this in a LaCrosse and slap the "GS" badge on it!

    Seriously, I wouldn't be surprised if this engine eventually makes it way into the Regal GS.

    :^)

    Agreed. Kill the 2.4L Regal, make the 220 HP 2.0T standard, keep the 255 HP as the new Turbo model, and make the 300+ HP 3.0TT the GS model.
