For a twin turbo V-6 isn't that a relatively weak hp number?....Heck, my FWD V-6 non turbo in my Impala has 305 HP.....just sayin' maybe torque is up but hp number for a v-6 twin turbo seems low....

In the CTS Vsport, the LF3 makes 420 horsepower (313 kW) and 430 lb.-ft. (583 Nm). In the XTS Vsport, the engine makes 410 horsepower (306 kW) and 369 lb.-ft. of torque (500 Nm). All figures are SAE-certified.

The above is what came to mind....the LF3....V-6 twin turbo 410-420 hp....The v6 in this new Caddy must be a different animal, and less powerful...

Sure...335 seems a tad low, considering the Camaro's stock V6 3.6 makes 335 HP, but not too bad when you consider a NA 3.0 V6 engine likely wouldn't be good for any more than 250 - 275 HP, but I don't really know of any run of the mill 3.0 V6 engines for reference.

But that torque number sounds excellent to me. I'd love to have that engine in my Colorado.

This has baffled me since the CT5 press release. The 3.0TT in the CT6 Sport is rated at 404 / 400, so why is the same engine in the CT5 rated at 335 / 400. I almost wonder if this isn't a typo transposing the hp for the 3.6L [335] and the torque for the 3.0TT [400].

The CT5 and CT6 versions have the same torque output. the only difference is hp. And it's a big difference.
