On this episode of Wide Open Throttle, Frank Markus checks out the 2013 GMC Terrain and evaluates at how its speed, performance, and comfort stack up against the segment's competition.

Mike Febbo hits the track with the 2013 Porsche Boxster S PDK, the completely redesigned third-generation model now equipped with (gasp!) electric power steering.

And Jessi Lang brings you an inside look at Autostadt, the stunning Germany-based automotive museum that recently granted Porsche its own pavilion.

Wide Open Throttle appears every Thursday on the new Motor Trend channel.
