Porsche Cayenne S: More horsepower and less weight

Porsche Cayenne S

Nice road test report here with the Porsche Cayenne S. Enjoy!

Alongside the weight loss and striking new exterior and interior design, Porsche squeezed an additional 15 hp from the Cayenne S’s naturally aspirated 4.8-liter V-8. A new transmission with two more forward ratios—there are eight now—helps to achieve EPA ratings of 16 mpg city and 22 highway. Although it works just fine by conventional-automatic standards, we feel spoiled by the PDK dual-clutch auto offered in the rest of Porsche’s range.

Nonetheless, with horsepower now at an even 400, the drivetrain improvements enable the Cayenne S to hit 60 mph in 5.5 seconds and clear the quarter-mile in 14.1 at 101 mph. Those numbers are an improvement of a half-second to 60, and 0.4 second and 3 mph in the quarter-mile. Notable as the Cayenne’s straight-line performance may be, it’s really the improvement in overall dynamics that makes it shine.
