Two engines and two transmissions are available. A 2.9-liter flat six rated at 255 horsepower motivates the base Boxster, good for 5.8-second 0-60 mph runs with the slick-shifting six-speed manual and 5.5 seconds to 60 mph with the even slicker PDK (dual-clutch) gearbox. The Boxster S gets the same transmission options but grows to 3.4 liters and 310 horsepower, lowering 0-60 mph times to 5.0 seconds with the stick and 4.9 seconds with the PDK. Add the Sport Chrono package to the PDK and you'll drop that to 4.7 seconds.
The Boxster Spyder offers even more performance through an extra 10 horsepower over the Boxster S and 176 pounds less weight. The result is a lither, nimbler, livelier drive, but at the expense of noise, a manual top in place of the standard power unit, and more expense.
The Boxster S Black Edition gets the same power rating as the Boxster Spyder, but with all of the creature comforts of the standard model, plus a blacked-out appearance treatment and higher standard equipment.
