GM Inside News reports that General Motors is working on a new turbocharged four-cylinder engine for the Cadillac ATS. The small-displacement engine is expected to produce between 270 and 280 horsepower. Those are impressive figures, though there's no indication as to whether or not the engine will require premium fuel.

If true, the engine's introduction only stokes the rumors indicating that GM is walking away from V6 drivetrain options in its mid-size offerings altogether. Automakers like Kia and Hyundai have already abandoned the six, allowing those companies to produce lighter, more efficient sedans that are just as powerful as their V6 competition.

GMI says that the new 2.0-liter will be cut from the same cloth as the 2.5-liter Ecotec four-cylinder that GM recently unveiled in the 2013 Chevrolet Malibu. In other words, while it may borrow some tricks from the turbo 2.0-liter lump that powers the Buick Regal GS, it will by and large be its own beast.

      If they drop the 3.6 , 280hp won't be enough. It will have to be at least 300hp, just to keep up with the competition for now. I don't see any reason, why they should dump the 3.6 when it's already at 315hp(?) in the Camaro. A 250hp 2.0 base engine would absolutely rock though. That'd be enough to beat out the competition.

        They're not dumping the 3.6, they're just not using in some cars anymore. Namely the Malibu. Other platforms will continue to use it. The Camaro, the CTS, the Imapala the Lamdba triplets, and most likely the ATS as well.

      Makes you wonder how effective those Lexus IS250s and Infiniti G25s will be in competing with these Caddy ATS's. Sit me down and sign me up.

      That seems to be a fitting engine for for the ATS base but I don't think Cadillac would enter a car without a V6 option. I can't see traditional Cadillac buyers willingly driving 4cyl turbos. That said, this car doesn't seem to be aimed at any traditional caddy buyers anyways and would lead a lot of credence to cadillac using a V6 in the ATS-V.

        There won't be a V6 in the V. It's most likely be getting GM's next generation LS V8 to compete with the 450hp the next generation RS4 (and current RS5), next generation M3, and the current C63 are all putting out. The higher up ATS that'll be competing with the 335i will most likely get an updated 3.6L DI with 330-350hp.

        Yep- This car is aimed at the Audi/BMW customers who traditionally are more tech savvy / younger buyers / don't know. Which is why the Night Vision technology never got traction in Caddys.

          Try adding horsepower to a naturally aspired caddy motor without spending more than $1000. Now try adding horsepower to a turbo motor with the same budget. The turbo motor will easily be able to see another 20-40% output with just exhaust and boost tweaks. My personal 2.0T is well over 400 at the wheels in my AWD Lancer Evolution.

          Acid, I've seen 30-40hp boosts on the 3.6DI in the Camaro. That's without forced induction.

      Since the CTS has 2 base engine options, I would see this engine as trying to match the 328i's entry-level power, with an optional V6 (probably based on the current or future Camaro engine) to rival the 335i.

        I always wonder if people like you are old enough to actually KNOW the Cimarron, have driven it etc. However, even if you don't have personal experience with it, to make any comment about it requires wisdom of how the car business works and an actual level of understanding of GMs current offerings and level of technical expertise. In short, if you had any of this plus some level of maturity you wouldn't make such a specious and out right stupid comment comparing this new as yet unseen vehicle to a 30 year old one.

        Keep in mind this car is going to compete with entry level luxury like A4, 3 series, C class, and the asians. It will be sold worldwide and a 280 hp turbo 4 is competitive in this car class. I am pretty certain there will be a higher performance V series version of this car at some If you want bigger engines then you buy the CTS.

        The A4/5, and C-Class have 4 bangers... The A4/5 comes with VW's tried and true 2.0L TFSI. The C-Class comes with a 1.8L 4 banger.

        I believe the word you're looking for is luxury. TheM Acura TSX didn't seem to be hurt by "having the worst engine sound there is" I see tons of those around. To compare it to the Cimmeron is completely retarded.

        Considering the BMW Z4 now has a 4 banger, how is this different? Mercedes-Benz C-class has a four as well. The ATS is supposed to be an entry level Cadillac anyways. In addition, most "luxery" cars today have so much cabin padding you can't even hear the engine. The ATS will be just fine with a four cylinder.

      Awesome. Nice to see GM is continuing their trend of recycling powerplants. The LNF ecotec has become GM's new bitch. Sad part is, it's a SAAB engine lol.

        Uh the LNF is an Opel engine. The engine wasn't even utilized in a Saab lol.

          LNF is a modern variant of the old SAAB 2L. It still uses the same SAAB crankshaft, complete with SAAB printed right on it.

        You do realize that car companies routinely keep the engine block relatively the same with small improvements around it, correct? Ford's 5.0 V8 is a modern technological update on the original, BMW's straight-6 has been modified slightly with each N-series revision but is still based on the same basic design principles, and the VW Group recycles engines between VW and Audi routinely. It takes a lot to develop an entirely new engine design from the ground up!

          "Ford's 5.0 V8 is a modern technological update on the original" No. The original 5.0 was a push rod motor with drastically different bore spacing, bore size, and stroke. I's mildly similar to the outgoing 4.6 but even then still has different dimensions. But no way at all is it related to the original 5.0. That's stretching it a bit too far there.

          The LNF is not old technology. And the LSx is definitely not old technology. No money in new powerplants? GM doesn't make any V6s for the US market except their newest one (3.6L). No more 90 degree V6s (3800s, etc.). No more high value V6s. Where do you get this stuff?

        Please show me proof of "SAAB" stamped on an LNF and that it's a variant of said engine instead of saying that it is. Just because it has a Saab component in it, doesn't actually mean it's a variant of the engine Saab used.

        The LNF is discontinued and died with the cancellation of the HHR SS and Cobalt SS. The LNF's successor, the LFU, is what's behind the Regal Turbo and GS, which has set an SAE record for the highest horsepower per liter ever tested. The LNF wasn't a SAAB engine either - it was designed in the U. S. Sure, it was based on a SAAB design, but they were owned by GM. If they hadn't borrowed resources across the board you'd be shouting that they were stupid not to have done so. The LNF was a great engine and the LFU should serve GM well in many applications - the ATS included.

        When will you wake up and realize that you're trolling on a car you hasn't even has its specs and official design revealed yet? So sad, troll. You're probably just sad that your beloved Lexus has replaced Buick/Cadillac as the grandpa's choice :)

      I like the idea of a small Cadillac, but they really ought to make a V-series for this car as well or it could go the way of the Cimmaron, and the Catera. Yes, but will it Zig?

      The 2.0L isn't cut from the same cloth as the new 2.5L in the Malibu. It's the same LNF Ecotec found in the Buick Regal GS, which is an updated version of the powerplant found in the Chevy Cobalt SS Turbo.

        Well, it's as *new as the 2.5 is, but then, the 2.5 isn't really *new. It's just been revised and improved in several areas. It's not a ground-up fresh engine or anything. Look for the latest 2.0 turbo to receive the same upgrades and improvements.

      Of course a 4-banger tweaked to put out so much power is going to require premium fuel.

        It doesn't in the two previous incarnations (LHU in Buicks, LNF before that).
