Dr. Ing. h.c. F. Porsche AG, Stuttgart, is presenting the second generation of the mid- engined Boxster and Cayman sports cars for the first time at the Los Angeles Motor Show. The high - light of the new generation is of course the new boxer engines developed with new technical features from the ground up, delivering not only more power, but also a lot more fuel-effi - ciency than their predecessors.

A further improvement of both fuel economy and performance is guaranteed by the Porsche- Doppelkupplungsgetriebe or PDK for short, Porsche’s new and revolutionary double-clutch gearbox.

The second generation of the Boxster and Cayman stands out clearly at first sight through the new, individually designed front and rear panels with even larger halogen headlights plus integrated direction indicators and new LED rear lights.

In the Boxster the 2.9-liter “basic” power plant develops 255 bhp (188 kW), with an even more powerful 265 bhp (195 kW) in the Cayman, that is an increase by 10 and, respectively, 20 bhp over the two former models. The 3.4-liter engine boasted in the S versions, bene - fiting from Direct Fuel Injection, now delivers 310 bhp (228 kW) in the Boxster S and 320 bhp (235 kW) in the Cayman S, an increase by 15 and, respectively, 25 bhp. And with their very low level of emissions, both power units naturally fulfill the ULEV emission standard in the USA and EU5 in Europe.

Offering an outstanding power-to-weight ratio between 4.2 kg (9.3 lb)/bhp in the Cayman S and 5.2 kg (11.5 lb) in the Boxster, all models in the range give the driver maximum per - formance on minimum fuel. This is also why the Cayman S with PDK and activated Launch Control in the optional Sports Chrono Package accelerates to 100 km/h or 62 mph in just 4.9 seconds, with the “slowest” model, the Boxster with its six-speed manual gearbox now featured as standard, completing the same dynamic exercise in an equally expressive 5.9 seconds.

Equipped with Porsche’s PDK double-clutch gearbox or Doppelkupplungsgetriebe, both the Boxster and the Cayman for the first time consume less than nine liters per 100 kilometers: To be specific, the models with the new 2.9-liter boxer engine require just 8.9 liters/100 kilo - meters according to the EU4 standard, equal to 26.3 mpg US, 11 per cent less than their respective predecessors with Tiptronic S. And reducing fuel consumption by an even more impressive 16 per cent to 9.2 liters/100 kilometers, equal to 25.5 mpg US, the increase in fuel economy on the 3.4-liter versions with PDK is even greater in comparison with their Tiptronic S predecessors.
