High fuel prices have car buyers looking away from V8 engines in favor of smaller, more efficient powertrains. GM is looking to feed the increased demand with an expansion of its Ramos, Mexico plant that builds its 3.6L V6 engines. The planned increase in output will allow the General to increase production of its next generation V6 engines an additional 350,000 units to a whopping 940,000 engines per year. The next generation HFV6 engines will also provide more of everything customers want, including improved fuel economy and a 6% increase in power. The engines will likely feature direct injection across the lineup this time. There is no word at this time if GM will change the displacement size for the next-gen HFV6 engines, but we did hear a couple weeks back that a Cadillac CTS wagon may feature a smaller 3.0L version of the engine in base form.

The HFV6 production increase was announced at the opening ceremony for Ramos' new six-speed transmission plant, which will also supply slush boxes for FWD crossovers and cars. The transmissions will replace the long in the tooth four-cogs (Yay!) and increase efficiency by up to 7 percent.

      Woo! I'm beginning to like the GM V6.
      • 7 Years Ago
      Put one in the Chevy Colorado.


      Trust me on this one.
        • 7 Years Ago
        Did GM put the 6L45 into the Colorado yet?
        What about variable INTAKE valve timing (for some torque)?

        That's a double no.

      Good news. The 3.6L is a great motor to replace V8s in crossovers and larger cars. Ive driven the CTS with the DI 3.6 with 304HP and that thing moves. I know the Chevy Traverse Crossover will use this motor with direct injection.
        • 7 Years Ago
        why dont they build the 3800 again so they can sell a buick......... the only redeeming quality of one...
        • 7 Years Ago
        I've also spent a good amount of time in CTS with the direct injection V6, and I agree with you. That thing is sweet. Glad to hear GM's spreading it out to more models.

      Why such a large V6? Where are the 2.5 and 3.0 versions? Throw a turbo or two on them and they would easily provide the power required in today's cars. Let alone better fuel economy than a 3.6L

        • 7 Years Ago
        GM has a 2.8 liter version. 89x74.8mm bore x stroke.
        They also have a 3.2 liter version 89x85.6, small bore of 2.8, with long stroke of 3.6.

        I'd like to see the large bore of the 3.6, 94mm, with the short stroke of the 2.8, for 3.1 liters.

        • 7 Years Ago
        Because 3.0L with turbo will cost a lot more than the naturally aspirated 3.6L. Maybe that's why you don't see many 3.0L turbo in other OEM's models?

        So easy to make smart suggestions when you are not paying.

      The UAW must be thrilled.
      • 7 Years Ago
      LOL, i bet by the time GM will start making almost a million V6's a year, gas will again become afordable.

        • 7 Years Ago
        Really? Do you have some sort of information you would like to share with everyone? I didn't think so, there are no real reasons right now to believe that gas will drop to a reasonable enough price that this would become a bad move, especially in the next year. I really wish the GM haters would just shut up.
        • 7 Years Ago
        Wow, your reasoning is iron-clad!
        • 7 Years Ago
        Yeah Mike, I totally agree.

        I think GM should bring back the V16 in the concept Caddy a couple years ago, and put that in everything from the CTS to the XLR.

        Then bring back the 8.1 big block, and put it in everything from the Torrent to the Malibu. I can see $1.29 / gal gas coming real soon...

        (yes, you're retarted)

        The oil companies Honda and Toyota are all in on it together to take the big three out!

        Sorry couldn't resist!

      These engines are also built in Flint Michigan
