2013 Cadillac ATS 2.0-liter turbo engineCadillac has just announced that the forthcoming 2013 ATS will come packing an available 2.0-liter turbocharged four-cylinder putting out an estimated 270 horsepower.

The engine features direct-injection, a twin-scroll turbo huffing 20 psi of boost, an air-to-air intercooler and variable valve timing, along with a forged-steel crankshaft and a two-stage variable displacement oil pump.

Cadillac claims the new 2.0-liter is 16 percent more efficient than the previous generation four-pot, and is able to deliver its peak 260 pound-feet of torque from 1,500 to 5,800 RPM.

Two other engines will be offered in the 2013 Cadillac ATS when it goes on sale next year, including a normally aspirated 2.5-liter four-cylinder and GM's tried-and-true 3.6-liter V6. Get the skinny in the press blast after the break and expect more details from next month's Detroit Auto Show.

New 2.0L Turbo Engine Boosts the Cadillac ATS

• 135 horsepower per liter among top-performing engines in the world
• Compact ATS debuts at North American International Auto Show in Detroit

DETROIT – A new high-performance 2.0L turbocharged four-cylinder engine will debut in the all-new 2013 Cadillac ATS compact luxury sedan, which will be revealed at the 2012 North American International Auto Show in January.

The Cadillac-tuned, direct-injected engine will produce an estimated 270 horsepower (201 kW). At 135 horsepower per liter, it will be one of the most power-dense automotive engines, besting the highest-performing engines from luxury competitors such as Audi, BMW and Mercedes.

"This engine is the perfect match for the new ATS, which will be a refined performance luxury sedan," said Don Butler, Cadillac vice president of Global Marketing. "The 2.0T has an exceptionally smooth and responsive power curve that will make the ATS nimble, quick and fun to drive."

The new 2.0T highlights a broad engine lineup that will power the ATS which is slated to begin production next summer. Cadillac will also offer a normally aspirated 2.5L four cylinder engine and a 3.6L V-6 engine in the ATS.

The 2.0T builds on the advanced-technology heritage of previous GM turbo engines with features that enhance efficiency, durability and refinement.

Among the 2.0T engine's highlights: a direct-injection twin-cam, four-valve-per-cylinder engine with continuously variable valve timing; twin-scroll turbocharger with air-to-air intercooler; forged-steel crankshaft with modular balance shaft system; and a two-stage variable-displacement oil pump with jet-spray piston cooling.

Overall engine friction is reduced by up to 16 percent. The low-friction design means engine power is delivered more efficiently.

Proprietary computational fluid dynamics analysis techniques were used to develop an all-new combustion system with a higher compression ratio, which also helped boost efficiency.

"The 2.0T is one of the most advanced and efficient engines of its kind, and contributes to the ATS's exceptional balance of performance and great fuel efficiency," said Mike Anderson, chief engineer for the 2.0T engine.

The 2.0T has a wide torque curve, delivering 90 percent of its peak 260 lb-ft. of torque (353 Nm) from 1,500 rpm to 5,800 rpm – giving the ATS the feeling of immediate power, whether from launch at a stop light or during higher-speed maneuvers, such as passing.

The turbocharger generates up to 20 pounds of boost and its twin-scroll design helps optimize power availability, virtually eliminating turbo lag and helping deliver a broad power band.

"It has the exhilarating, responsive power available when you want it, yet can provide the fuel efficiency that will make the ATS a fully competitive vehicle in global markets," Anderson said.
At 135 hp/L, the ATS 2.0T four-cylinder turbo engine has the highest power density among key competitors, including:

• Audi A4's 2.0L turbo (105.5 hp/L)
• BMW M3's V-8 (103.5 hp/L)
• Lexus IS F's V-8 (83.2 hp/L)
• Mercedes-Benz C250's 1.8L turbo (111.6 hp/L)

Additional details on the ATS will be announced at the 2012 NAIAS. The ATS will be built at the Lansing Grand River plant alongside the Cadillac CTS Sedan, Coupe and Sport Wagon and V-Series performance cars.

      I hardly wait to see this car fully uncovered, to test drive it and ultimately buy it. I am on a holding pattern with the purchase of a new bmw 3 series, but waiting for this car to come out, especially with my latest desire to buy a good American made product.
      • 3 Years Ago
      I'm glad GM apparently learned from the inept Regal launch and decided to put something other than the weak base engine in the initial model. After all, this initial car is the one that most reviewers will be driving and offering their opinions on.

      Who said this is the the top line ATS engine? The V will have more power. The LNF is a angine that has yet to see all the improvments and refinements yet. I drive daily a 290 HP LNF and just love it. The GM upgrade brought this engine to life and added 1-2 more MPG with my add HP. Most GM Turbo and SC engines are tuned to use Regular and Premium. The computer holds the timing and boost to levels safe for what fuel you choose. Most times it cost about 20 HP for regular. Cars like a Cadillac or ZR1 using premium should not be an issue as if you buy a car like this and can not afford the few extra cents for the better fuel then you bought the wrong car to start with. The ATS and the Turbo should make for a nice package at a good price. I am interested in the V package we have yet to hear about. I expect it will see at least 400 HP or more. We do have some Turbo 6 cylinder engines coming soon.

        As a fellow LNF owner I agree completely. My car is Trifecta tuned and I am doing well over 300TQ at the flywheel and should be around 300HP flywheel too. :)

      Just a quick typo note. FTA: "... and GM's tried-and-true 3.5-liter V6." I'm pretty sure this is meant to say "3.6-liter V6," as the press release confirms.

        Autoblog got their American car companies mixed up. Either that, or they forgot that GM stopped making a 3.5L V6 some years ago.

      A lot of the European ppl dont buy American cars is for the fact that the engines are to large for their backyards. The reason why u might ask? The govt slaps a fat tax of anything over 2000 CC, yea its nuts. Say its 2004 CC, that will be slapped with a min 200 euros per year on taxes. Their system is a lot stranger then others. Big engines are taxed heavily. Ex mustang/camaro with their 3.7L will be somewhere over 1000 euros per year, every year depending which euro state u live in. BTW, 270 hp is dam well for 4 banger. Wonder how much psi can the engine handle before it pops...
        • 3 Years Ago
        @Dam plm
        well it can probably handle more then 20 considering this same engine makes 325 HP in the euro nations. besides everything over there costs more. There was a piece on car insurance in Great Britain that Top Gear did and it was an astronomical price for someone just starting out.

      *sigh* Too bad there's no small RWD car like the Solstice/Sky to put this in.
        • 3 Years Ago
        I own the Sky Redline and I view this as the spiritual successor to the engine in my car. I am very excited to see where this engine ends up as GM tries to ease the cost of R&D. Even if for now it's only in the ATS, I'm still very excited at the prospects. My little engine is a beaut and I am thrilled to finally see another 2.0T putting out not only similar, but higher numbers. Thank you, GM.
        • 3 Years Ago
        There doesn't need to be, if you're a fan of the Solstice, buy a used GXP, it's 260hp stock and can be bumped to 290hp easily with a simple reflash(stock warranty intact).

          They're fat, have a small boot, and an interior made by fisher price.
      • 3 Years Ago
      I think this is going to be the hot car of next year. It looks amazing and GM,—an organization with literally dozens of amazing cars in its history—has its engineering prowess back. This car will hit the streets the most developed Cadillac ever, imho.
      • 3 Years Ago
      "260 pound-feet of torque from 1,500" That sounds pretty darn good. And if its as tunable as many turbo'ed engines, you should be able to see 300+ HP with some fairly simple mods.

      The HP numbers all sound great... but how much will it weigh...

      C-Class attacker?
      • 3 Years Ago
      I'm totally open to a 4 banger BUT I'll wait for the performance figures to cast judgement. That thing better sing! If not, I suppose GM's V6 has things covered :D
