Rumorpile: ATS-V Packing A 425 Horsepower Twin-Turbo V6

How about the ATS-V uses the 425hp 3.6L Turbo with the 7-speed manual and the updated CTS-V shares the new ZO6 drivetrain. That will be a big + IMHO.

Just my opinion, but wouldn't it be smarter in this scenario to make the 3.6TT the Vsport and then the actual V the other higher performance option?

Putting the 3.6TT from the CTS V-Sport into an ATS V-Sport would be ideal.... with V8s to follow.

I am still of the opinion that none of these publications actually know what's under the hood of the ATS-V. Unlike the Z06 there had been no actual credible leaks, just rumors. To me, it's still 50/50 between the LT1 V8 and the 3.6TT. Here's why...

Case for the LT1 V8

• This maintains the Cadillac V-car tradition of using Corvette motors and makes the V-car powertrain philosophy consistent if they use the 625+ bhp LT4 in the CTS-V (which I am quite sure will be the case)
• While the 211 kg LT1 is 28kg heavier than the LS3, this is by far the lighter, more compact, more powerful and more torquey motor (compared to the LF3 V6 which weighs 220kg)
• That LT1 is also somewhat cheaper than the LF3 allowing for money to be put into other performance equipment
• Fuel Economy will be 1~2 mpg worse than in the lighter & sleeker Corvette, but 16/27 mpg is more than competitive in a 455 bhp car

Case for the LF3 V6TT

• The XTS and CTS already use this motor, using it adds fewer discrete engines to the Cadillac lineup
• There are those who believe that Cadillac should do what the Europeans do, the BMW M3 is now a turbo 6
• For markets with a displacement tax, the 3.6 liter powerplant may have a tax advantage over the 6.2 liter
• I project the 3.6TT beating the 6.2 V8 by 1 mpg in the City, although it remains to be seen if there is any advantage on the Freeway. Given the ATS's lighter mass over the CTS Vsport, expect 1~2mpg better mileage -- at least 17/26 mpg, perhaps 17/27. Again, very good numbers, but not clearly superior to the pushrod V8.

As far as the Alfa Romeo 3.2 based TT? I don't know where that came from. That was and is never in the cards.

Wouldn't there also be the push to make Cadillac more distinct from the rest of GM? You want the Camaros and ATS Coupes to be sold well without being seen as the same car if they share the same engines.

The Turbo V6 is in the XTS exclusively and the Impala only gets the regular 3.6L V6.

The same may apply with the high-performance models of each brand. The ATS-V will get the turbo V6 and the next-gen Camaro will get the LT1.

I think the CTS V-sport powertrain is the ATS-V powertrain. It keeps that set up as Cadillac only and the work is already done and they have some economies of scale there. The 3-series is what Cadillac is going for and the M3 has a turbo 6, I just feel like that decision on a turbo V6 was made long ago.

The 3.6TT, with a low slung AWD system, would be awesome underneath a GMC Canyon Syclone.

YES!!!!!!!!!!!!

agree OCN.

Ocn stop stealing my Syclone and Typhoon line!

A modern Syclone and Typhoon would be cool...even cooler would be an Escalade V series w/ the CTS-V engine.

An Escalade V was considered as they had mules running around with the Supercharged V8, but was killed due to the depression and the killing of the old GM and move to the new GM. 3rd party Superchargers on the escalades are amazing. Have a friend that like me has a 2006 Escalade ESV Platinum that he supercharged and while it requires Premium, it is freakin amazing to drive.

I agree with you that they need a V series in all their auto lines.

Escalade V

SRX V

XTS V

CTS V

ATS V

Isn't this 5HP more than the M3/M4 engine?

2013 M3 4L V8 414HP @ 8300 rpm; 295 lb-ft of torque @ 3900 rpm

2015 M3/M4 3L I-6 425hp @ 7600 rpm; 406 lb-ft of torque @ 1800 rpm plus 170lbs lighter than the previous version.

6.2L V8 (L86) with Overhead Valve, two valves per cylinder, variable valve timing, Direct Fuel injection, 11.5:1 compression and regular fuel, max RPM 6000, 420 HP @ 5600 rpm, 450 lb-ft @ 4100 rpm.

3.6L v6 TT (LF3) with dual overhead cam, four valves per cylinder, variable valve timing, Direct Fuel injection, 9.5:1 compression and premium fuel required, max RPM 6500, 420 HP @ 5750 rpm, 430 lb-ft @ 3500 rpm.

But the ATS is lighter than the 3-series also.

Three things...

(1) The L86 is used in the Silverado pickup truck. If the ATS uses the V8, it'll much more likely be the LT1 used in the Corvette. The LT1 makes 460 hp @ 6000 rpm / 465 lb-ft @ 4600 rpm.

(2) The LF3 3.6L TT V6 actually has 10.2:1 compression (not 9.5) -- per GM official statistics.

(3) Contrary to what many people think, the Twin Turbo V6 is the heavier engine. The 6.2L LT1 V8 weighs 465 lbs vs the 3.6L LF3 V6's 485 lbs -- both GM's official numbers. For comparison, BMW's S65 4.0L DOHC V8 weighs 445 lbs whereas the previous generation LS3 port injected pushrod V8 weighed 403 lbs.

BTW, the ATS is only very slightly lighter than the F30 3-series. The ATS 2.0T weighs 3,373 lbs equipped with the Hydramtic 6L45 6-speed auto. The BMW 328i 2.0T weighs 3,410 lbs equipped with the ZF 8HP 8-speed transmission. Still, it's the first time a GM platform has a weigh advatnage over Bavarian and Stuttgart stuff.
