Here’s Motor Trend putting the superb Porsche Cayman R through its paces. Powered by a 330 bhp 3.4L flat six, the R cracks 100 km/h (62 mph) in 5 seconds, but that time comes down to 4.7 seconds on cars fitted with the optional seven-speed PDK transmission and the Sport Chrono package. Top speed with the manual transmission is 282 km/h (175 mph), and 280 km/h (174 mph) with the PDK.
