What do you to say to a mix of the Porsche 918 Spyder concept and the amazing 911 GT3 R Hybrid all in one racing Porsche 918 RSR? The model, revealed at the 2011 Detroit Auto Show, is the next hybrid step in Porsche’s model range and is, again, nothing short of impressive. The 918 RSR is a kind of prototype preview of the technology that Porsche will use on future racing models, and even if you’re not into the new wave of environmental tech and the pressure put on sports car companies like Porsche, the results have been astonishing with models like these - enough to please any petrol head out there.

The Porsche 918 RSR has the same drivetrain set-up as the 911 GT3 R Hybrid, although this latest version gets even more power. The new V8 is based on that which appeared on the 918 Spyder and produces 563 hp. The rest of the hair-raising power is provided by two front-wheel electric motors, each producing another 102 hp to make for a total of 767 hp combined. It uses the same flywheel accumulator as the GT3 R Hybrid for extra energy storage (like having a powerful, onboard generator) and the front electric motors are equipped with a torque vectoring function for variable torque distribution.

Further aspects include a six-speed, racing transmission with paddle shift and the chassis is a carbon fibre, reinforced plastic (CFRP) monocoque. The accumulator mentioned above sits where the passenger seat would originally be, making this a one-pilot car, and it can be used for power boosts of up to eight seconds. Below you can find all the pics live from Detroit, along with the press release.

In order to reduce overall CO2 emissions across the Porsche range, the company is planning at least one hybrid drivetrain in every model line. There is already a Porsche Cayenne hybrid and the Porsche 911 GT3 R Hybrid proves that they can make whopping sports cars with hybrid technology, although there are no plans in the near future to go to production across the coupé line.

The Porsche Cayenne hybrid will be joined by a Panamera hybrid sometime in 2011 and which will use the same platform as the SUV. The only electric-powered sports car to appear at this stage will be the 918 Spyder which will have a smaller production run and should appear in three to four years’ time.

While the 911, Boxster and Cayman are currently off the list, development manager at Porsche, Wolfgang Duerheimer said: “We want to learn how we can electrify all our sports cars in the future with the help of this short production run.” No time frame has been given for those models, but the hybrid roll-out plan is to meet the goal of reducing CO2 emissions to 216 g/km by 2015, from 255 now.

Other measures being considered are the use of smaller, four-cylinder engines and lighter-weight vehicles. The use of carbon fibre will likely spread across the Porsche range, saving around 50 kg on each new model. It’s a big challenge for a brand like Porsche, and it will be interesting to see just how it tackles the problems in coming years. Still, it’s good to see the investment being made while still keeping to the brand’s core values. Aston produced the Cygnet, Porsche is going hybrid….

After the news that Porsche will go ahead with production of its 918 Spyder concept, and will put three electric Boxsters through testing, Autocar tests the 911 GT3 R Hybrid. It’s interesting to note that Autocar describes it as the rarest and most sophisticated 911 ever built by Porsche, which gives us some indication as to the seriousness of Porsche’s investment in electric and hybrid technology.

The big question for purists though, is whether a hybrid Porsche will ever be as good as an original 911. The 911 GT3 R Hybrid is hugely technological and very powerful with the classic flat six engine giving 480 hp, to which another 160 hp is added to by the hybrid set-up. It’s quite amazing really - it looks like being in a simulator with all the electronics going on but you’re actually flat-out on the track.

Frankly, nothing short of “phenomenal” and “incredible”. The GT3 R Hybrid is a top quality race car, hybrid or not. Check out the video for all the technical details but in the meantime, Porsche has certainly impressed the socks off me.

The Porsche 911 GT3 R Hybrid and Cayenne S Hybrid get their own video in this “Two concepts, one idea: Efficiency” video from Porsche. Both models’ hybrid systems have been developed through the Porsche Intelligent Performance program. At the 2010 Geneva motor show we also saw the Porsche 918 Spyder Concept which also combines traditional fuel technology with an electric motor. See more of the 911 GT3 R Hybrid and Cayenne S Hybrid models in the video.

The Porsche 911 GT3 R Hybrid will debut at the 2010 Geneva Motor Show, but only as a virtual presence before its real official debut at the Nurburgring 24 hours. The 911 GT3 R Hybrid is purely a race car with amazing power of its own, subsequently increased in an electric motor booster, with energy recovery during braking sent to the front wheels for all wheel drive.

The hybrid version is based on the GT3 R and will also be equipped with the flat six, four-litre engine with 480 hp. The space originally dedicated to the passenger will be replaced by a flywheel which collects and generates the energy saved in braking, which then distributes it to two motors in the bonnet.

The additional power can be measured as 60 kW for each motor, and is activated by pressing a button on the steering wheel. An extra 160 hp is then produced for a time between six and eight seconds. The KERS flywheel system also keeps fuel consumption down, reducing the need for refilling.
