Scheduled for sale as 2010 models next year, the latest Cayman and Boxster can be pointed out from the other models by their slightly modified headlights, air intakes, and LED tail lights. This is the first time that both versions are offered with Lights Package highlighting bi-xenon headlights, active curve lights and LED daytime driving lights. The fog lights are replaced with LED lights; on the Boxster four LEDs are placed side by side, while on the Cayman they are arranged in a circle.

The prominent feature of the latest series is the most current flat-six boxer motors designed with fresh engineering attributes from the ground up, offering not just extra power, but also considerably greater fuel economy than their precursors.

The addition of the new Porsche-Doppelkupplungsgetriebe (PDK) dual-clutch gearbox also enhanced both fuel efficiency and performance. With a displacement of 2.9 liters, the base engine now generates 255hp (188kW) in the Boxster and 265hp (195kW) in the Cayman, an improvement of 10hp and 20hp, respectively in contrast to the preceding versions. The 3.4-liter power engine in the S-versions, taking advantage of the direct fuel injection, now provides 31 0hp (228 kW) in the Boxster S and 320hp (235kW) in the Cayman S, up by 15 and 25hp, respectively.
