2010 Cadillac SRX 2.8T – Click above for high-res image gallery

It's never been a secret that General Motors wants to expand the plug-in hybrid technology from the Chevrolet Volt to other models and the Cadillac SRX crossover has been one rumored candidate and today, during an interview about the powertrain used in the Volt (specifically the gas tank, which we'll have more about later), Jon Stec, fuel system integration engineer for the Volt, said the following:

We've got another plug-in coming, which is the 166, the SRX, which is the same basic technology.

Even though the SRX would make a great platform for a plug-in powertrain, either by converting the current model or redesigning it for electric mobility – a GM spokesman on the call clarified that a SRX PHEV program does not officially exist, but we look forward to the day when everyone just opens up about where the Volt's guts go in the GM family.

As to what 166 means, we're not sure, but a few years ago the number was apparently used as a code name for a sedan built on the midsize Epsilon platform.

      These are exactly the kind of vehicles where this makes the most sense - if people will buy them. But these are the people with the money to afford it and might have enough guilt to do it.

      I still wish they had put the EREV tech into the Orlando. The Prius V wagon is a pretty good idea, too bad GM didn't beat Toyota to the punch.

      This is probably referring to the 2-Mode plugin hybrid from the Saturn Vue, not the Volt drivetrain.
      • 4 Years Ago
      GOOD! Do this. They can hide some of the drivetrain price in the inflated Cadillac price. Get production scales up!

        Also Cadillac has the right image to sell a car, which is extremely expensive. This one might end at 60k$, but that's a much more "normal" number for a luxury mid size SUV than 40k for a normal compact.

      I think this is a great idea. My biggest complaint about living in cities is that you can't shut your engine off and scoot along in electric when waiting in traffic, or when driving in a drive through. You have to keep your engine running. This can save a lot of fuel in the big picture and save a lot of pollution when idling. And if it makes an SUV owner "look" better then oh well.

      Uuuggghhh! I can think of much better places to use the Volt's technology! I know you want expand your hybrid line, but most people that buy the SRX, don't give a crap about efficiency! They just want to look "good" in thier tank, err SUX, no SUV!
        • 4 Years Ago
        I agree that many people when they focus on efficiency realize "Why am I driving a 4,224 pound fat ugly tank in the first place?" and get a Prius. But some people need or want an SUV, and the plain embarrassment factor of a SRX AWD getting 17 city /23 highway mpg, compared with a 2011 Highlander Hybrid's 28 / 28 or Lexus RX450h 30 / 28, has to affect sales. Even for the domestic automakers, there's a small market for hybrid SUVs, and a plug-in hybrid SUV would have little or no direct competition for a few years.

        2010 hybrid sales from http://www.hybridcars.com/hybrid-clean-diesel-sales-dashboard/december-2010.html :
        Lexus RX450h: 15,113
        Toyota Highlander Hybrid: 7,456 (old model)
        Cadillac Escalade hybrid: 1,210
        Chevy Tahoe hybrid: 1,426
        GMC Yukon hybrid: 1,221
        etc.

      I think this is a great choice, if the range can be made to be suitable without the price going wild.
        • 4 Years Ago
        I totally agree. This move will further popularize and elevate the voltech powertrain.
      • 4 Years Ago
      GM is simply following Toyota's very successful example with the Lexus range.

      Linking Cadillac to the Volt, will enhance the desirability of the Volt in the eyes of potential buyers. I will also revitalise the once great name of Cadillac

      I am looking for a Hybrid C max competitor from GM ( say the hybrid power train in an Orlando ) ( not high priced entry minivan (like uplander ) with a hybrid power train ).

      Yes i live in Canada :-)

      GM had displayed a cool looking Cadillac concept that was supposed to use the "E-Flex" power-train, but it never got past the concept stage. As for this, it sounds more like a vague rumor than an actual concept.

      Delays in offering a plug-in Caddy is going to cost GM big-time, they'll lose market share to Fiskar and Tesla, and possibly even to Lexus and Mercedes and BMW and Lincoln and Rolls Royce, too.
