Porsche Promises Fuel Economy with Cayenne SUV

As it prepares to launch its first hybrid vehicle this weekend—the Cayenne S Hybrid—Porsche announced that it is achieving significant fuel savings in all its new-generation Cayenne models.

With consumption reductions of 20 to 21 percent in its overall EPA fuel economy rating (with the hybrid), the 2011 Cayenne sport utility vehicle has achieved its goal of improved fuel efficiency and the reduction of greenhouse gas emissions, the company says.

While paying homage to the first Porsche model to bear the Speedster name – the 356 Speedster – Porsche also announced that a new 911 Speedster will make its debut at the Paris Motor Show. (Read: Porsche 911 Speedster to Debut at Paris Motor Show)

Among its other marketing moves, Porsche Cars North America (PCNA) had launched a campaign: My Classic Porsche Search. This national search was to focus on finding the oldest Porsches in 12 distinctive model categories, as well as the very oldest Porsche of all. (Read: Can You Search the Oldest Porsche?)

The basic principle of the “Porsche Intelligent Performance” philosophy, which is providing more power with lower consumption, increased efficiency, and reduced CO2 emissions, particularly applies to the new Cayenne model series that went on sale this year.

In a related development, Green Car Journal has announced its five finalists for the 2011 Green Car of the Year, including the 2011 Chevrolet Volt, 2011 Ford Fiesta, 2011 Hyundai Sonata Hybrid, 2011 Lincoln MKZ Hybrid and the 2011 Nissan LEAF.

The six-cylinder Cayenne model consumes 20 percent less fuel than its predecessor, while the V8 Cayenne S and Cayenne Turbo models have enjoyed similar reductions. At the same time, all of these new vehicles offer more power and better performance, according to the company.

This reduction in consumption across the entire Cayenne range, it says, can partly be attributed to use of the new eight-speed Tiptronic S automatic transmission with automatic stop/start function and a wide gear ratio range.

Also critical to the improved efficiency is the Cayenne’s weight reduction and intelligent lightweight construction.

Engineers used a weight-optimized material mix and modified the vehicle’s overall construction, which included the development and use of a new lighter-weight four-wheel drive system.

This 400-pound weight loss not only helped improve the Cayenne’s overall fuel consumption and CO2 emissions but also improved performance, agility, and handling, the company says.

The new highlight within the model series – the Cayenne S Hybrid – features a sophisticated parallel full hybrid drive system, which delivers even more impressive figures, it claims.

Offering the performance of a V8 with the economy of a V6, it combines the power output of a supercharged V6 combustion engine with an electric motor.

The Cayenne S Hybrid has official fuel consumption estimates using current EPA test protocols of 21 mpg in the city and 25 mpg on the highway, Porsche said in a statement Wednesday, Oct. 27.
