I decided to have a look. I found no mention of hp and torque, but it's a tidy little package.

The headline says non-US markets, but the text says Japan only. Maybe Canada? In Japan it's for their Winter weather.
It's mentioned in this article that has a video that talks about active grille shutter, temperature sensing steering wheel and 15" low rolling resistance tires (but not the E-Four).

It doesn't say whose tire, but there is a Bridgstone Ecopia in the right size.
