Cadillac XTS Platinum concept unveiled at 2010 Detroit Auto Show – Click above for high-res image gallery

Back in January, we watched as Cadillac took the wraps off of its big XTS Platinum sedan concept under the Detroit Auto Show lights. And while parent company General Motors insisted on slapping the word "concept" behind the car's name, we were pretty sure that the XTS we saw in Cobo Hall was very close to being production-ready.

Now, a new report from Motor Trend states that GM has, in fact, given the Cadillac XTS the go-ahead. When it hits the streets, the XTS will replace both the aging STS and DTS in the Cadillac lineup, and will feature a plug-in hybrid system mated to a 3.6-liter direct-injection V6 – the system originally developed for the Saturn Vue. MT also reports that a twin-turbocharged version of the 3.6-liter V6 could be in the works, and that GM hasn't necessarily ruled out the option of shoving a big ol' V8 under the Caddy's hood.

GM is also working hard to ensure that the XTS's high-zoot interior remains intact for the production car (or, as close as it can get). Cadillac is hoping to offer some proper competition for top-end German luxury cars with the XTS, and we'll know how it fares when it hits the road next year, badged as a 2012 model.

      Lackluster mileage with a 2-mode hybrid system, plugging it in will probably only get you 5-6 miles of range max.

      Sounds less green & less appealing than the model s & fisker karma. And the styling looks a little too modern for the blue hairs who currently drive cadillacs. But is they make it flex fueled and build it in the usa I am sure there are quite a few blue haired congressmen who will "buy american" and "save the earth" by "filling the tank with corn".

      It may be the perfect car to drive to washington the next time you need to get bailed out for making bad decisions.

        Granted, the fuel economy won't be as good as the Model S or Karma, or even the "Converj Concept" that GM dropped. But on the other hand, it will have much better fuel economy than any other Cadillac in history, and it might even exceed 50 mpg if regularly plugged in.

        I wouldn't expect it to become the best selling GM car, but it might become the best selling Cadillac. It should appeal to Caddy lovers that want to get better fuel economy.

      Meh. It is not for me but it is a step in the right direction. And anything that increases the production volume of electric motors, chargers, controllers, and batteries gets my blessing.

      "If it's going against the Germans, it better be RWD. "

      It will have the same formula as Audi and considering BMW is going to start going FWD, this won't be any different.

      I like the styling of this car. A lot of journalists and commenters have complained about it having long overhangs. Maybe the trunk is a bit long past the tires, but the front is not long at all. If it's going against the Germans, it better be RWD. You can't beat steak with tofu.

      plugin hybrid should really excite us except noone in their right might combines a battery electric drive with a 3.6L combustion engine in a road cruiser. you get plenty of acceleration power from the battery drive so all you need the combustion engine for is the range extension. the average power output. not 300HP. and a 3.6L engine is a heavy piece of shit. not something you want onboard in the energy effiency accounting.
      so logic dictates this is not a sincere effort. it'll likely just be very expensive and low volume.

      fiber glass aerodynamic battery electric car with bare minimum combustion engine for range extension. learn that sentence.

        Exactly Dan,

        It's just plain stupid to do a plug in hybrid with a huge V6 and a big, fat, heavy cantankerous transmission to go with it. That's dumb and half-a$$ed.

        Just upgrade the Volt drivetrain with more batteries and a more powerful electric drive. Then throw in a DI 4cyl engine as a series/parallel genset.

        Come on, GM! It's not rocket science, for crying out loud.

        Actually rockets are far simpler technology.

        the Volt actually has plenty batteries already. probably too much for an optimal solution because they chose to have 100% redundancy of the battery pack for the 40 mile range which is a very dubious decision since the batteries is the one critical cost item.
        so if you just took the volt pack and allowed 80-90% use of the capacity it should have plenty power for acceleration beyond the normal gas version. and that's really the way to sell electrics I think. if they outperform. and since it's so easy to make electrics outperform gas it's very stupid not to. of course it has to do with the fact that big auto doesn't want electrics to make gas look bad..

        as for the ICE, short of developing an engine series specifically for range extenders (which they most certainly should) I'd look at something like the 3 cylinder 1L engines that go into the mini cars of europe like citroen C1. it has 68 ponies peak which is plenty for cruising a caddy at freeway speeds at the engines most efficient point. maybe add a fancier fuel injection if it doesn't have it already.
        if designed from scratch I'd look at 2 cylinders or even 1 and I would try a rocker engine with desmo valves instead of a piston that scrapes on the side of the cylinder wall and valves that waste energy with springs forced down by friction in impertfect timing.

        and of course the car itself should be rebuilt as? that's right, aerodynamic fiberglass car. monocoque. lean and mean. no overweight wheels. fiber wheel hub and airless tires. it's all wrong and easy to fix. they are just not thinking.
