Chris Harris hits the track in the Porsche 911 GT3 RS

One of the wonderful things about Chris Harris on Cars is the enthusiasm that the host brings to the screen. Granted, it would be hard not to enjoy a day driving around in a supercar that you don't own. Still, Harris brings a sense that he knows how rare these opportunities are and relishes them. In his latest look at the two sides of the latest Porsche 911 GT3 RS, you can tell this guy is having a lot of fun.

The GT3 RS is a 500-horsepower, track-focused weapon, but it's expected to drive to and away from the circuit after a day of laps. Therefore, Harris decides to evaluate the attributes of this Porsche in both environments. On the road, he sweeps an orange example over some beautifully, undulating German backroads but keeps things rather tidy. However, in the latter half of the video, he arrives at the Weissach test track for a go in a purple RS. There, he really lets the rear hang out.
