New 2.0L Turbo Engine Boosts the Cadillac ATS
Link to Press Release

December 14, 2011

• 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.

Direct Injection for the WIN!!!! Watch this thing when the tuners are done with it....500-600-700 hp? Just watch.

[Zabo]

At 270hp stock tune, this thing is already on the level with the LT1. Granted the combined HP/TQ figures will never truly match the LT1 lb for lb when both are modified. But with half the cylinders and less than half the displacement..

Has anyone indicated whether or not they did a semi revival of the Allante name with the ATS?

CTS: Catera Touring Sedan
ATS: Allante Touring Sedan
STS: Seville Touring Sedan
DTS: DeVille Touring Sedan

Meanwhile
XTS: Extra Large Touring Sedan
SRX: Sexy Redundant Crossover?
Escalade: Repo Magnet



Hey Fen, you going to NAIAS? If so gimmie a shout, I plan on going opening day.

[Kyle2k]

Three engine choices already? Hmmm. Will the ATS-V end up being a turbo 6?

[TheCaptain]

Zabo, SRX= Sport Recreational X-over.

That would be my guess. Even though it wouldn't be as good of an engine choice as a next gen V8, from a manufacturing & engineering standpoint it would be the way to go for that car.

Ohh boy, here we go GM is playing with the blower again lol.

Probably not...small chance I'll go the next weekend...depends on what GM brings really. ATS/Encore are nice, but Sonic RS/K2XX Silverado concept/??? Chevrolet concept are going to have to blow me away.

2.5L (Supposedly for export markets only)
2.0T
3.6L LFX V6
6.2L LT1 V8

Techinically, its a hair dryer or snail. Blowers are mechanically driven superchargers

[JamesNoBrakes]

Audi TTRS, 2.5L 144hp/L.
Audi TTS 2.0L 132.5hp/L.
Mitsubishi 2.0L 145.5hp/L.

Cool that GM is doing this, twin scroll, etc, it's about time obviously, but if GM's going to boast about the hp/L, lets see some other good ones listed, rather than using their "lowest hp/L engines". They also don't import to the US some of the more impressive japanese 2.0L turbocharged engines with twin-scroll turbos and the like, these also do upwards of 140hp/L easy.

At least GM seems to be "doing it right", rather than just some low pressure turbo or tons of lag.

Respectfully disagree, I'd argue from those points you menchioned that a Gen V V8 makes more sense. A. I dont see a TTV6 being any smaller or lighter and definetly not cheaper than the Gen V V8, obviously the V8 would be more powerful to. B. Merc. BMW, and Audi performance cars don't standout from each other anymore imo. GM is in a postion to be what BMW USED TO BE and more!!! The ultimate driving machine. An ATS-V with a Gen V V8 and 7 speed manual trans would give the ATS its own identity and character. Cadilac need to "Standout" NOT "Blend in".

[JusticePete]

Packaging makes the 2.0L very attractive as in it fits in a smaller area.

The ATS is designed to accommodate a traditional GM V8.

[ParisTNDude]

Now that's a car I'd be willing to trade my Camaro for. I always loved the tiny mouse motor in the Cobalt TC engined cars and since they've added direct injection, this engine has tons of potential as one poster already said: 400, 500, 600 HP. It's getting funner and funner every day!!!

Put this in the Cruze GM!
