*Sorry, Please move to ATS forum:

The 2.0L turbo I-4 engine that powers the all-new Cadillac ATS is one of WardsAuto.com 2013 “10 Best Engines” for North America.

The 2.0L turbo’s 272 horsepower is the highest specific output of any GM production engine, and at 136 hp per liter, is the most power-dense engine certified by the Society of Automotive Engineers.

“The 2.0L turbo 4-cylinder is a stout performer that impressed all the WardsAuto editors,” said Tom Murphy, executive editor of WardsAuto.com. “It muscled its way back into the winners’ circle with remarkable horsepower per liter, and the engineers deserve kudos for reducing engine friction some 16 percent, which means it runs smoother and more efficiently.”

Murphy added, “This engine gets four mpg better on the highway than the earlier version did a year ago in the Buick Regal GS, a former Ward’s 10 Best Engines honoree. That’s impressive. If the ATS can nibble into the market share of well-established German brands, the 2.0L turbo should get most of the credit.”

ATS’s lightweight and aerodynamic design allows it to accelerate from 0-60 in 5.9 seconds when equipped with the 2.0L turbo engine, while delivering EPA-rated fuel economy of 21 city and 31 highway mpg.

Ward’s reviewed 40 engines from 16 automakers in this year’s competition. Winners were chosen based on several factors, including power, fuel efficiency, new technology, refinement, and comparative data for similar engines.

The 2.0L turbo engine includes the latest in technology combinations.

“Benchmark efficiency and refinement were our top priorities when developing the all-new 2.0L turbo,” said Mike Anderson, global chief engineer for Ecotec engines. “The team was focused on using technology to reduce friction and engine noise and also managed to take specific output to a new level.”

Among the 2.0L turbo 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.

The 2.0L turbo 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 new 2.0L turbo engine is also used on the Chevrolet Malibu and is built in Tonawanda, N.Y.:thumbsup:

The 2.0L turbo ATS is priced at $35,795, including destination (excluding tax, title, license and dealer fees) and offers automatic and manual transmissions, and rear- or all-wheel drive. ATS also is available with a standard 2.5L four-cylinder, and a 3.6L V-6 is available.

I'm sure I'd get less than 21 mpg city, but it would probably be related to the dent in the floorboard underneath the accelerator pedal... :thumbsup:
The ATS I had as a loaner for a week was kind of a fun ride, but I was happy to return to my SRX which I could get in an out of without looking like I was 100 years old...

I see these small turbos as the future of mid sized cars and the associated down-the-road maintenance with them is going to make buying a used car hell for a lot of people. Turbos are great if the engine is up to the car's weight and performance standards. But if the engine is put into a car that is too heavy for it it will die an early death. I can see GM putting one in the future SRX and would expect it to suffer. The main problem with small turbos is that if they are in a heavier car the user knows the power is there and uses it much too often. The basic engine is not large enough to handle everyday driving thus the need for the turbo. The best combination is for a healthy sized engine coupled with a turbo for sports car like performance when needed and not everyday driving. There are no free lunches, except in DC, so you can pay for it now or you can pay for it in the future. The oil coking problem in turbos has been solved by an electric pump that continues the oil flow after the engine is shut down but you can bet that most manufacturers will not offer one. If any of you have ever had to replace a turbo you know how expensive they can be. I had a Porsche 930 turbo for several years and it was a delight to drive but the basic engine was up to the requirements of the basic car and not a band-aid to a too small engine.

GM bought Saab in part to get their turbo and emissions control technology. It's good to see they are finally popularizing what we fortunate few knew and drove for the past thirty-five years.

I've owned and driven the Saab 2.0 and 2.3 turbos since they debuted in 1978. Have three turbo Saabs at present and the turbo technology is the only thing I miss in our fourth, my wife's 3.0 9-4X. I stayed away from the 2.8 because for some reason Saab was never as successful with the turbo V6. Their turbo fours were better than VW/Audi, but Audi owns the twin turbo V6.

We have built the ecotech 4 cylinder to nearly 1000 HP and this motor is far better. Anyone that wants to take the jump were looking for one to see what we can accomplish.
