Exelent Cars 13

Porsche tuner RUF Automobile is developing ten electric vehicles with three different powertrains based on the 911 Carrera (997), which will be put to the test in “real life situations”. The prototypes are being manufactured in cooperation with German electronics giant Siemens AG and are going to be presented in the first half of 2011. The three eRUF variants feature a single motor concept, twin

It's no secret that Porsche is working on a new model to further expand its range in the SUV segment. In fact, the German sports car maker not only confirmed the vehicle but also announced that it is being developed under the working name "Cajun". Further details remain unknown including of course the Cajun's styling direction and whether or not it will be a three-door (most likely) or five-door model.

Nevertheless, Teamspeed member and rendering specialist Wild-Speed has come up with a styling proposal for the Cajun. The artist designed the crossover as a three-door model with a sloping roofline incorporating styling elements from the latest Cayenne, Panamera and the 918 Spyder (notice the head lamps). You can check out the renderings in high resolution after the jump.

Porsche decided to keep the production version of the 918 Spyder under wraps for now showing off instead the motorsport-inspired 918 RSR Coupe Concept at the 2011 Detroit Auto Show. Combining hybrid racing technology with a dramatic looking coupe body style, the RSR is every bit as impressive as the design study showcased last year at Geneva. For its motivation, the 918 RSR relies on a V8 gasoline engine delivering 563HP and a pair of electric motors producing a combined output of 204HP. Check out our gallery with live pictures from the Detroit show after the break or click here for more details on Porsche's conceptual racer.

Porsche's return to the Detroit Show after a four year-absence is marked with the introduction of a new racing concept based on the company's 918 Spyder from last year's Geneva Salon. The 918 RSR is a two-seat mid-engined coupe, and according to Porsche, it demonstrates what happens when the technology fitted in the 911 GT3 R Hybrid race car and the design of the 918 Spyder concept are combined together.

The motorsports version of the 918 Spyder concept car gets a V8 engine based on the RS Spyder race car's 3.4-liter unit tuned to deliver 563HP at 10,300 rpm, and is linked to a six-speed racing transmission with shift paddles that feeds the rear wheels.

A pair of electrics motors mounted on the two front wheels each contribute 75 kW (102 hp), or a total of 204HP, lifting the combined output to 767HP. The German maker notes that the extra power from the electric motors is available for around eight seconds when the system is fully charged.

As with the 911 GT3 R hybrid racing car, the additional power from the electric motors, which is generated during braking, is stored in an optimized flywheel accumulator.

In the 918 RSR study, the two electric motors also offer a torque vectoring function with variable torque distribution to the front axle, which increases agility and improves steering response.

Aside from the coupe configuration with the fixed roof and the characteristic doors which open at an angle upwards, the 918 RSR also features an added air intake in the roof between the wing doors, a special aero package that includes air splitters beneath the front lip and a huge rear wing, plus slick tires on 19-inch wheels with single centre locking nut.

The interior of the road-spec 918 Spyder has also been modified and comes with a single figure-hugging bucket seat, while the passenger seat has been replaced by flywheel accumulator.
