It was announced some time ago that the 2015 Cadillac ATS Coupe would feature 272 horsepower and 295 pound-feet of torque from its base 2.0L turbocharged engine, giving it an edge over the 2014 ATS Sedan in the power department, which has only 260 lb-ft. Not so with the 2015 model, as the 2015 ATS Sedan powered by the 2.0-liter turbocharged four-cylinder engine joins its two-door brother with an equal gain in twisting force.
Engine calibration resulting in increased boost pressure allowed for the additional torque, and at 136 horsepower per liter, the 2.0-liter turbo is one of the most power-dense engines in production. A broad torque band (90% of peak torque from 2100 rpm to 3000 rpm and full torque from 3000 rpm to 4600 rpm) is supported by high boost levels in the speed range.
“The ATS is already the most agile vehicle in its respective classes,” said David Masch, the Cadillac ATS’ chief engineer. “The additional torque works to further improve on an already dynamic vehicle.”
Also new to the 2015 ATS Coupe and Sedan are Lane Change Alert and Lane Keep Assist. Drivers are alerted to vehicles in and approaching their blind spots by flashing symbol lights on the mirrors once a turn signal has been activated. When traveling faster than 37 mph, the ATS uses a camera to detect if the vehicle leaves its lane unintentionally, and can nudge the power steering to correct.
Comments
Torque does not equal power. Horse power (power – rate of doing work) is dependent upon torque (force) and time (RPM actually). Toque and RPM are both measurable quantities, where as power is calculated from those measured values.
Did the ATS sedan get a power bump?
This will help in the mid range area.
The Torque in these engines is what really is impressive. Mine will light the tires up rolling down the road with no issue.
I just wish GM would move the power up to over 300 HP and about 325-340 FT LBS as they did with the GM performance upgrade kit. The kit could do 290 HP with no issues and the torque is at 315 in my limited FWD transaxle but 340 FT LBS in the manual Solstice.
There is no reason that the car can’t do this.
Refinement is the answer. That engine at it’s current output isn’t the most refined in-class, especially compared to Merc’s new heavy hitting 2.0 (CLA 45 AMG), plus you would almost be guaranteed to lose the flat, and broad range, torque curve through the revs.
The refinement I am in full agreement on.
As for the flat torque curve you can still increase the power and torque ands still keep the torque relatively flat based on the engines I have seen built up. To be honest 315 FT LBS at the bottom end is all you need in most cars as you will never get the car to hook up anyways. If you use the engine management to hook up it just slows you down. My Launch control is slower than if you foot it out.
I would rather see it increased as it goes up and not add anymore to the bottom end.
Hell I can spin my tires on smooth pavement now at 55 MPH to the point the traction control kicks in. The first time it happened I thought I broke something with the car died and the light came on.
I would like more power for the pull at speed and just a bump in torque as it moves up.
325 HP and 340 FT LBS is very easy to do in a LNF now. I expect with a improved refined engine they should be able to meet these number or more.
The three things that have held back GM have been. FWD in the older platforms. Transmission warranties in the 4 speed and 5 speed transaxles and the fact GM likes the Premium fuel Recommended rating. This way the owner can choose the fuel. The GM upgrade bumps you to Premium Required. It is silly when you are getting 25 City and 32 Highway to worry about fuel cost but many car buyers do and GM wants to not scare them off.
I have my boost light set to light off at 23 PSI and it amazing to think this is in a simple street car doing this. It was not all that long ago Race cars were the only thing that could hit 20 PSI and a street car was amazing to hit 12 PSI.
But in the Cadillac the Eco need to be more refined in the intake and exhaust NHV.
The Stage II Cobalt SS loses the flat torque curve it had when stock, non-factory tuned. It starts to dive around 4k rpm.
Taking that 2.0 in the ATS up to 340lb-ft from factory would make it a mess and perception would suffer. Pushing a 2.0T too much is why Hyundai dialled theirs back a bit.
If an ATS owner want 325hp and lb-ft they can spend a few hundred at Trifecta/BNR or Pfadt and deal with the high strung engine. I’m not against it, it’s what I would do, but I am against it being that way from factory.
This a nice increase! Makes me wonder how nice this same engine would be in a Colorado. Do it GM! The market has spoken, they love turbocharged engines that have both power and efficiency.
I still wish GM would implement the successful IVVL technology into all of its DOHC Engines (including the 2.0t). The 2.0t should also get VTM or “overboost” technology. With their current engines, I think:
2.5L I4 (VVT, SIDI, and IVVL) with 205HP and 195LB-FT
2.0t I4 (VVT and SIDI) with 275HP and 295-310LB-FT
3.6tt V6 (VVT and SIDI) with 450HP and 460-475LB-FT
What Cadillac really needs to focus on is their engines’ refinement and powerband.
As for the next generation or refresh:
1.6t I4 (VVT, SIDI, IVVL, and VTM) with 205HP and 210-225LB-FT
2.5tdi I4 (VVT, IVVL, and VTM) with 225HP and 310-325LB-FT
2.0t I4 (VVT, SIDI, IVVL, and VTM) with 290HP and 300-315LB-FT
3.2t V6 (VVT, SIDI, IVVL, and VTM) with 380HP and 395-410LB-FT
3.6tt V6 (VVT, SIDI, IVVL, and VTM) with 470HP and 480-495LB-FT
It’s nice to see the 2.0T get a torque increase. Should be somewhat more powerful at least. I would like to see greater strides taken to refine the engine. But when will the 8-speed become available on the ATS? This engine desperately needs it!!! Especially in the CTS.
A power increase is never a bad thing, but I think the transmission is the biggest issue for the ATS. Let’s face it, this car is chasing BMW’s 328i, and though the ATS have more advertised power, I doubt it will beat the BMW in any speed contest. Yes, the ATS has the superior chassis, and BMW’s engine is underrated, but it’s the wonderful 8 speed transmission, working in harmony with the very refined engine that sets the BMW apart. The frustrating thing is GM knows this, and they do have the 8 speed, so what’s the problem, GM?
You can’t just stick an 8-Speed in a vehicle. I am sure they are working on it as of now and it will be out in a couple of years. Who knows, it could even be in the ATS-V!
I wish GM would offer the damn LED running lights on the Luxury model!?!? Or at least offer it as an aftermarket part. I noticed on the Cadillac forums I was definitely not alone when I drive up and saw my car had no LED’s in a stores reflection. All the 3 series, A4’s C class etc have them. They want to stand out here in Toronto, they should be bold like the CTS’s are. They make a statement for sure.
