Those who have been keeping score at home were probably already expecting this, but Cadillac has officially announced that the 2013 ATS will debut an all-new 2.0L turbocharged Ecotec four cylinder engine rated at an estimated 270 horsepower and 260 pound-feet of torque. That translates to 135 horsepower per liter, which is equal to the current 2.0L Ecotec turbo found in the larger 2012 Buick Regal GS, but 35 lb.-ft. behind in the torque department. Fuel economy numbers have yet to be published, but don’t be surprised to see a rating of 30 MPG or more in the future.
What’s different about the new 2.0L is significant. For instance, the exhaust and intake are now opposite from where they used to be. The exhaust manifold has now been integrated into the cylinder head, and the engine will rev to a significant 6,800 RPM. Additionally, the new twin-scroll turbocharger supplied by Eaton will replace the Borg-Warner spool seen in the Regal GS. Then there is the attention to detail in noise reduction efforts, with significantly more fasteners clamping everything together. The 86mm x 86mm bore and stroke dimensions stay the same. The new engine will be assembled at GM’s Spring Hill, TN and Tonawanda, NY engine facilities.
Cadillac also mentions that GM’s naturally aspirated, more docile 2.5L Ecotec engine will make its way into the ATS, along with the popular 3.6L LFX V6 engine, which produces 318 horsepower in the larger CTS. There is a significant power difference between the three mills, and should give consumers the luxury of performance variety when the ATS launches in the summer of 2012. As for what will power the impending V edition, all signs point to something along the lines of a twin-turbo V6 flavor.

Not sure about offering the 2.5 liter yet… Other choices are good ones though
wait but how come this new engine has less torque than the Regal GS?
Manoli the 2.5 in the ats will be a premium version with some changes to engine as well as calibration, Twin turbo quick spool will be the V version and it is quick and handles like it is on rails. watch out germany the Americans are coming.
What’s the big deal with this motor,remember the LNF,or is this the same motor.Look what turbo upgrade does.Power gains of 30 horsepower (22 kW) and as much as 80 lb.-ft. of torque (108 Nm) are achievable with GMPP’s Turbo Upgrade Kit (part number 19212670, MSRP $650). It fits vehicles powered by the LNF 2.0L turbocharged engine, including the Cobalt SS, HHR SS, the Pontiac Solstice GXP and Saturn Sky Red Line.
The power boost ratchets output from 260 hp (194 kW) and 260 lb.-ft. (352 Nm) to 290 hp (216 kW) and up to a robust 340 lb.-ft. (461 Nm) – turning already potent performers into certified powerhouses. Torque levels vary, depending on the model and/or transmission.
I can think of one good reason why GM elected not to go with a HI-PO T/C engine.
Consider where GM would like the ATS to break ground. The answer is “Everywhere”, but I imagine that Europe is high on that list. Many nations in Europe tax cars on CO2 emmissions. In the ATS’s case, a lower HP/TQ engine would put the ATS in a more favourable road tax bracket.
Conversely, it could be argued that those in Europe who want an ATS won’t care their amount of road tax (or their gas bill, something which I have neglected to bring up because I thought it was obvious and well established). That may be, but whatever can give Cadillac a better foothold than what the BLS and past efforts in Europe have failed to do, the better. The ATS won’t smash the 3 into submission, but at least GM can say they’ve tried.
Also, HI-PO versions of any car are ALWAYS outsold by their garden variety versions. Not everyone who buys luxury cars does so for higher HP and TQ ratings. Heck, BMW has known that for decades and that hasn’t stopped them.
I wonder if this would fit as a replacement engine into the cobalt ss turbo as the intake and exhaust are now opposite. Just in case my engine goes keep the car running forever…
320hp and 350 tq
