On the track with five different Porsches

Birmingham, Alabama. Porsche recently invited a group of journalists to test five of their cars on the track -- and not the least: a base Cayman, the popular Boxster S, the new 911 Targa 4S as well as the powerful 911 Turbo and GT3. The event was held at the Barber Motorsports Park, which is the North American home of the Porsche Sport Driving School (PSDS).
