2010 Cadillac XTS Platinum Concept – Click above for high-res image gallery

Traditionally, Cadillac buyers have been a V8-loving bunch. Over the past decade, the V6 came into vogue, but the four-cylinder has never really entered the discussion – until now. Car and Driver reports that Cadillac will offer turbocharged four-cylinder engines in the ATS and XTS. C/D opined that the engine of choice could be the 2.0-liter turbo that currently resides under the hood of the Buick Regal.

Based on current and (known) future applications of the 2.0-liter turbo, expect output to be somewhere between 220 and 260 horsepower, though we'd likely bet that even higher output could be in store. We wouldn't be surprised if the full-sized XTS featured a turbocharged version of the 2.5-liter four that will soon find itself under the hood of the 2013 Malibu. That way, General Motors could still offer 300-plus horsepower from a powertrain that is likely more efficient than the automaker's similarly powerful V6 offerings. Cadillac can also help nudge power northward and further improve fuel efficiency with hybrid and plug-in powertrains.

While smaller powertrains are inevitable in the world of high gas-prices and increased fuel economy standards, getting Cadillac fans to buy into a four-pot mill could still be a challenge. But if gas prices continue to charge northward, we're guessing some consumers will actually accept the diminutive power sources with open arms. If that happens, we can expect Cadillac to offer the next generation SRX and CTS with a four-cylinder option, as well.

      If they can get 300 HP from the 2.5 4cyl I would give it a test drive! Every premium brand will have turbo 4 cylinders and 6 cylinders if they are to meet the new fuel regulations by 2015. The biggest challenge facing Cadillac is weight savings not engine size, if they offer a 2.5 and no one buys them they will still have the 3.0 to sell but if it is to heavy that will really kill them!

      If they build the Cadillac Sixteen, I won't mind whatever they put in other vehicles of the line-up.

        It has every bit as much to do with establishing a "green" image as increasing mpg. The common consensus is "smaller displacements = better fuel economy".

      Anyone who has driven the current Caddy V6s know they are powerful, but need to get to high rpms to access that power. If Caddy can make a 260+HP turbo 4 that has good power without getting to 5500rpms, then it will be a good fit for their vehicles. It day-to-day use it would work well. So I await their offerings, the right ones could be a big hit.

      "Traditionally, Cadillac buyers have been a V8-loving bunch." Nonsense. Traditionally Cadillac owners have looked for seamless power and back then a big honkin' V8 was the only way that GM knew how to make power. But a modern V6 or even a 4 is more than good enough for most applications. However having said that, the XTS will definitely be an aspirational vehicle. People that would buy it probably want something to "show off". Having even a turbo-4 might be a little too little for this crowd. Unless its backed by some kind of hybrid or EV technology, I don't think Cadillac's range-topper should have a 4 cylinder engine, even as its base powerplant.

        I bet it will have some sort of hybrid assist just to be able to market it as such. I think it will be quite a high-tech drivetrain when all is said and done.

        I wholeheartedly agree: CTS: 2.0T (280hp), 3.6L V6 (320hp) and, the V8 V-series (Direct injection+Turbo @ 4.6-5.0L) XTS: 320hp V6, 400-ish hp V8, and forced induction V8 V-series (Direct injection+Turbo @ 5.0-5.7L) ATS: 2.5L I-4 (200?), 2.0T (280), 3.6 V6 (320) and DI Turbo-6 V-series (@ 3.2-3.5L)

      Audi has successfully selling 4-cyl premium cars for some time now. There's no reason others can't follow. But I wonder if Cadillac buyers really cross-shop against European or Japanese brands or if they're cross shopping against other lower GM brands.

        I know I cross-shopped against European and Japanese makes. I used to have an Audi A6, now I have a Cadillac. I can't speak for other Cadillac buyers, to be honest I think a lot of them don't do so. Cadillac dealers (at least mine) still seem geared toward selling Escalades and SRXes. The CTS also sells, but the existence of it has not transformed their customer base nor their employee base, at least not in my area. And having been to south Florida, it doesn't look transformed there either. The CTS is a big hit with the blue hairs there.

      Cadillac needs to stop screwing around and make an STS replacement that looks like this.

        Audi's entire lineup being FWD-based isn't a problem when nearly all their cars sold are AWD. Audi needs to update their 4-cylinder. It's aging and is still cast-iron block, so is quite heavy. In most applications, it also manages only about 100hp/liter, which is fine, but not great in the turbo-four world.

        Considering they're losing sleep over Buick, you're right! Or, you're not.

        Huh right. They both have been sleeping soundly at the wheel for a while now, especially Lexus who is also really good at making their drivers fall asleep at the wheel.

          Brian - It's funny that you respond to a generalization about Lexus by pointing out the only 2 models Lexus builds that have any modicum of excitement (despite the fact that no one can really even buy an LF-A), and then you make the same generalization about Cadillac, while ignoring the CTS-V. Hypocrite.

          Yes, the TL SH AWD is a snoozer. Yes, the TSX V6 is a snoozer. The IS-F is a disappointment but I think boring would be an exaggeration. Much higher quality interiors than Cadillacs? You're insane. A friend has a TL. My CTS interior is much better. And as to the idea that Cadillacs never have been fun to drive, you should read some reviews. The CTS is already fun to drive. Cadillac does have to figure out how to spread this across their line. Perhaps they will do so, perhaps not.

          I actually think the IS-F is great, just a tad questionable-looking, and I share similar feelings with the TL SH-AWD (available in manual!). Lexus are boring and over-engineered (ask Top Gear), and Cadillacs and boring and under-engineered (see:interior, which is okay for a cheaper car, but not a luxury car).

        You know, Cadillac outsold Acura last year. And Buick + Cadillac outsold Lexus by over 30%. In fact, Buick and Cadillac had the highest growth rates last year of all brands. http://www.autoblog.com/2011/01/04/by-the-numbers-2010-the-year-after-that-really-bad-year-editi/ Acura and Lexus should be losing sleep.

        It sounds like you need to lay off the peacepipe!! Lexus? Seriously? Yeah, they are so exciting that I could not even name one of their models. The few I happen to notice just look like Camrys and Avalons with different badges, or some bland looking CUV. As for Acura? The only thing that comes to mind is that hideous beak that makes me want to puke every time I see it. It's a shame because the TL was a nice looking car ten years ago. Though Cadillacs are not my cup of tea, I love the styling of this and the specs of the CTS/STS Vs. Acura and Lexus may match up well against Lincoln, but they are no competition for Cadillac, MB, or BMW.

        Wow, you are a rocket scientist. Cram V8s in all the Cadillacs with $5.00, maybe $6.00 gas and GM will be back on Capitol Hill, on their knees, begging for another handout on 5 years. I don't know where you get the idea the EcoBoost is a "gas guzzler". The 3.6 litre V6 CTS AWD gets 18/27 while the bigger and more powerful (51 hp) Lincoln MKS EcoBoost Gets 17/25.

      Oh no...this 4-cylinder business is sickening. Lets hope the 4-pot is "no-excuses" powerful and doesn't hum or buzz or thrash. Furthermore, they'll need to engineer or synthesize a "proper" exhaust note.
