RUF Developing Electric Test Vehicles Based on the Porsche 911 Carrera

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 motor concept with 2-speed gearbox and twin motor concept with torque vectoring.

The first powertrain comprises a 180 kW (241HP) electric motor, 29 kWh lithium-ion battery and standard Porsche gearbox used for speed reduction. The setup offers an estimated driving range of 150 km (93 miles) and decent performance: 0 to 100 km/h (62 mph) in 7 seconds and a top speed of 220 km/h (137 mph).

The prototypes using the twin motor concept are even faster, reaching 100 km/h (62 mph) in about 5 seconds, while also maxing out at 220 km/h or 137 mph. Two synchronous electric motors deliver 250 kW (335HP) and are coupled to a 2-speed automatic transmission. The more potent battery pack (36,6 kWh) extends the driving range to 200 km (124 mph).

Last but not least, the third variant uses the same twin motor setup, while adding torque vectoring into the mix as well. Engineers mounted two separate gearboxes into the car, each powering a rear wheel. Acceleration and driving range are the same, however estimated top speed decreases to about 180 km/h (112 mph).

The field test are expected to provide important data on the different battery and powertrain setups, which will be handed over to the German Federal Ministry of the Environment, also involved in the project.

Porsche Quietly Rolls Out Pure-Electric Boxster E Prototypes

In a German-language only press release and without much fanfare, Porsche announced the introduction of a trio of electric-powered Boxster E prototypes. Over the next few months, these pure-electric test vehicles will be trialed in and around the city of Stuttgart to provide feedback on the feasibility and usability of the concept in everyday use.

Porsche is keeping mum on most of the details surrounding the three prototype Boxster roadsters simply stating that the cars are equipped with two-electric motors that deliver up to 180kW or 241-horsepower, and are fed through a 29-kWh battery package.

Artist's Rendition of 2013 Porsche Cajun Small SUV

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 918 RSR Coupe Concept: Live Photos from Detroit

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.

World Premiere for Porsche 918 RSR Coupe Concept at Detroit Show

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.

Porsche's Detroit Motor Show World Premiere Rumored to be 918 Coupe Racer

We already know that Porsche plans to debut a new model at the rapidly approaching North American International Auto Show (NAIAS) in Detroit next week, but the problem is that the German sports car maker is keeping its cards close to its chest about the type of vehicle it will unveil.

Adding to the many rumors already circulating on the internet, Bloomberg today reported that the model in question will be a racing coupe version of the 918 Spyder hybrid concept that was first shown at last year's Geneva Show.

Citing two people with knowledge of the matter, the news agency said that the car will be a two-seater concept coupe featuring a 600-horsepower V8. We'll remind you that the 918 Spyder, which was recently approved for a limited production run, gets a 500HP 3.4 liter V8 electro-enhanced by way of motors that add another 160 kW (218 hp).

We'll monitor the story and post an update if anything new arises, but for now, check out some renderings of a competition 918 made by a member of the Teamspeed forums in the video below.
