General Motors has revealed the first details of an all-new high-performance 2.0L turbocharged four-cylinder engine that will debut in the 2013 Cadillac ATS next month at the Detroit Motor Show.

The direct-injection power unit boasts an impressive 270hp ( 201kW / 273 PS) and 353 Nm (260 lb-ft. ) of torque . With power-density rated at 135hp (100 kW /136 PS) per liter, it makes this power unit one of the best performing engines in its class. General Motors has compared the ATS 2.0-liter turbo to its key competitors: the Audi A4 2.0L turbo (105.5 hp/L), BMW M3 V-8 (103.5 hp/L), Lexus IS F V-8 (83.2 hp/L) and Mercedes-Benz C250 1.8L turbo (111.6 hp/L).

The unit has been developed with a low-friction design and 90 percent of the peak torque is available from as low as 1,500 rpm giving the new ATS a good thrust at low and high speeds.

"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 engine also features a number of highlights, these include:

  • 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
  • Two-stage variable-displacement oil pump with jet-spray piston cooling.

The new 2013 Cadillac ATS will also benefit from two further engine options. These are a naturally aspirated 2.5L four cylinder engine and a 3.6L V-6 engine.

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

Yawn. Wake me up, when straight 6 cyl. engines come back in fashion.

Buddy, no offense but if you manage to yawn while I take you for a drive around the track in my 4 cyl 267hp, 350Nm engine, I'll take my hat off for you. Surely a 6 cyl is a superior engine but these little 4cyl are real beasts these days.

This is a new, state-of-the-art engine, much like the 2.0 Ecoboost by Ford and BMW's new 2.0 turbo. The engines in the Evo and in the Hyundai, like the GM Ecotec in the Buick Regal GS, are somewhat older designs that are not maximized for low friction and other characteristics. Fine engines all, but this one makes the upcoming ATS (with rear drive like a Bimmer) worth waiting for!

Hyundai 2.0L Turbo 274hp, 5 year 100,000km warranty....Why didn't they compare it to that, or the 2.0L in the STI or EVO.

Comparing this to the NA V8 in BMW is pretty stupid. What's the point, really? a FI engine makes more power/liter than a NA engine?

+++! And this guy wouldn't like to talk about other aspects of an engine such as reliability that give the competition the edge!

Great news. I have the 267hp 2.0l engine and I love its punch. This should be even better in the ATS. I hope we get this car in Europe RHD.
