Saw this thinly disguised 1 hour comercial on Speed channel yesterday. Focus was on the new SRT8 line-up. Since I own the previous Gen Jeep SRT8 - I was interested in the overall performance. They took the Jeept to the 'Ring with a professional (female) driver and did a lap in under 9 mins. I think that is a very good time for an SUV brick.
These things weigh in at 5K lbs and the new version makes 470HP at the flywheel. A lot of new features as well where the driver can adjust sport/track and street modes remotely via 'selector' that controls engine AND chassis stiifness + anti-roll/sway.
I LOVE mine and after driving a few other manufacturers offerings, nothing comes close. Really nothing at all from the domestics. My $.02
