Cadillac STS Forum - 2005 through 2012 Discussion, Whats faster ? An sts v6 or a cts v6 ? in Past Cadillac Vehicle Discussion; 0-60
Costs more doesn't necessarily mean faster I understand ....
Assuming you mean an STS and CTS equipped with the same 3.6 V6, Motor Trend (for all they're worth...) quotes 0-60 as 6.6 for the CTS and 6.8 for the STS. 1/4 mile the same 15.0 for both with the STS having a slightly higher trap speed (92.7 vs 92.0).
i would think the STS is faster.
while the STS is about 160lbs more, it does have about 40hp more and almost 60lb-ft more torque.
there are a million other factors, but just going by numbers, id say the v6 STS. the only real way to see is to test (race) them
They both have the exact same 3.6L V6 producing 255hp. The transmission gearing is different though between the automatics (most likely to help get the STS moving with it's extra mass).
So which is the fastest?
The 3.6L V6 CTS with the 6 speed manual.
