This entire announcement is about a motor that will be offered in the CTS and the XTS.
The ATS-V is still vaporware, ATs and MTs alike.
Still.... GM says the new CTS will do a "0-60 mile per hour time of 4.6 seconds" and the ATS should be faster than that with the same engine. An ATS-V would almost certainly have a higher output engine than the base CTS.
'think about how they spaced out the HP numbers between ZR1, ZL1 and CTS-V for the 6.2'
I am astounded like everyone else with these numbers... But you do realize that the TTV6, even though it sounds really potent and capable, is not considered a performance engine. If anything the LF3 will be in the CTS and XTS AWD Platinum trims. Those three cars you mentioned are the top of the line for their models. This is my logic for the Alpha chassis performance cars and the vehicle from Bowling Green:
ATS-V: Tuned LT1.
CTS-V3/ZL1-2: F/I LT1 with modest boost/tune.
ZR1-2: F/I LT1 with agressive boost/tune
It would be great to see an LT1 V8 in the ATS-V (think about the tuning headroom of that) but I for one would be surprised it if happened. I, like others, expect a higher output TT V6 making similar power to the LT1.
Stop reading rumors.
They REALLY need to officially announce the ATS-V and its specs. Tho I bet it is going to be this exact same motor with the same HP and torque. Still, i think we are looking at about a 4 second 0-60 time in the lighter ATS
"A 2014 Cadillac ATS-V with the twin turbo engine would not gain much front end weight over the current car with its top engine, the normally breathing 3.6 liter V6. The car would jump from about 320 horsepower up to about 420. With its approximately 3700 curb weight this rear-drive car would be one of GM’s fastest vehicles - ever. Only the Camaro ZL 1, the Corvette, and maybe the CTS-V would have a better power to weight ratio. Our own Patrick Rall wrote that the CTS with this engine would likely have a 0-60 mph time of about 4.6 seconds. That it very fast. However, an ATS-V with the same engine would be a car that could reach 60 in under 4 seconds.The technical term for that is “Stupid fast.” There would only be 3 single cars in the GM line-up that could compete with it."
I would like to see mileage comparisons between a TTV6 vs a well tuned small block V8. With an eight speed trans geared for each motor I wouldn't expect too much difference. Also the V8 should be less costly to build.
And an LSx naturally aspirated V8 would be less complex, would sound better and might take up less space in the engine bay. Americans need to stick with what works; adjust engine mix in other models to play with mind-numbing CAFE. Too much talk about an automatic transmission, what about a manual?Quote:

Has anyone considered how a TTV6 would sound and whether it would be appropriate for a halo car like a "V"? Angry insect is pretty obnoxious.
No one cares about manuals anymore. Even the car rags prefer autos.
Some say this the golden age of automotive performance. Its looking like the dark ages to me. Stupid fast and fun to drive are two very different things.
