Porsche 911 GT3 R Hybrid

Porsche has launched an app for all smartphone-using Porsche owners to tap into the social networking realm with the Drive + app for the Apple iPhone, iPod touch and iPad.

With the Drive+ app, Porsche owners can upload media of taking Porsche out for a spin, while viewing a new model at an auto show, or even watching a Porsche race around a track. This brings the Porsche community together in ways that were previously unimaginable.

There are several functions to the app, including:

– Upload multiple photos and videos
– Live feed
– Beautiful Dashboard
– Recent Activity, Popular and Featured Views
– Full web version
– Integrated Facebook and Twitter

Picture quickly slicing through the mountain roads in an all-new 2013 Porsche Boxster S, stopping for a meal somewhere in between. Using the Drive + app, a photograph can be taken and uploaded, while sending out a message seeking out other Porsche drivers who would like to join in on the fun.

Perhaps it’s a track day with the new 911. A video of the high-velocity excitement can be taken and then uploaded in between hot-laps, along with a status update inviting friends to come on out. We’ve all thought it would be cool to integrate social media into such a hobby as driving. Now through Porsche, we can.

Porsche Hybrid Technology Hauls Ass and Saves Gas

by Sales Team on October 30, 2011

At the recent ModSpace American Le Mans Monterey Race, Porsche rolled in with the 911 GT3 R Hybrid and delivered quite the beating to every car in the GT class as drivers, Romain Dumas and Richard Lietz, finished 10th overall. Not only did Porsche’s gas-electric superstar post the fastest lap, it made just three pit stops in the six hour event, compared to the five everyone else made. Porsche is changing what everyone thinks about hybrids by proving gas-electric technology can haul ass and save gas.


“The start phase was huge fun, because it was relatively easy to overtake the slower competitors,” Dumas said after the race. “But it’s even more fun because we can apply superior tactics thanks to the lower fuel consumption. We are much more flexible and we made the most of this day.” It was the car’s first appearance on the West Coast (and only its second in North America since it debut last year.)

Based on the 911 GT3 R, this hybrid isn’t a traditional hybrid in a sense that it uses a kinetic energy recovery system, and instead of a battery, the energy is stored in the flywheel. The system store 0.2 kWh of energy, which is enough to provide an additional 150 kW (203 horsepower) for an eight second burst. “That doesn’t sound like much, but the system recharges quickly,” said Dieter Steinhauser, head of motorsport R&D. “For performance applications, a battery recharges too slowly.”

The flywheel, mounted where the passenger seat would be, spins up to 40,000 RPM. It powers a pair of 75 kW (101 hp) motors, one per front wheel. The rear wheels are driven by a 4.0-liter flat-six which is good for 470 horsepower.

The 911 GT3 R doesn’t fit into any one of the five classes in American Le Mans, therefore it essentially is an experimental car. Which means, it cannot participate in qualifying and must line up in the back of the grid. The car started in 35th which makes the climb to the 10th spot that much more impressive.

“It’s a shame that we weren’t permitted to join the qualifying, we could have done with the extra practice for finding a good set-up,” Dumas said. “I last drove the car at Road Atlanta. Compared to last year’s version, the 2.0 has made huge progress.” The hybrid system in version 2.0 weighs 120 kg, 50 less than the first generation. The electric flywheel is about 90 percent efficient, and the hybrid delivers a 10 percent improvement in fuel economy over the conventional 911 GT3 R race cars. Porsche also reduced the weight of the car, which comes in at 1,300 kg.

So far the 911 GT3 R Hybrid is just a showcase for Porsche’s Intelligent Performance advanced drivetrains, but a similar system will be available in the gorgeous 918 RSR race car. Porsche hopes to see the American Le Mans Series create a classification for hybrid drivetrains in time for the 2014 season.

People would not normally associate high-performance sports cars with fuel-efficient technologies like gasoline-electric hybrid power, but that could be one of the biggest misconceptions. Better efficiency often translates to better power, and in the world of racing, this should be a significant consideration. Since technologies proven on the race track tend to trickle down to the street over time, the application of hybrid power with speed is a move in the right direction. Porsche has been a leader in this race and the 911 GT3 R Hybrid is one example.

The new 911 GT3 R Hybrid exemplifies the ‘Porsche Intelligent Performance’ philosophy which is applied to every Porsche. A philosophy defined by the goal of ‘more power on less fuel, more efficiency and lower CO2 emissions,’ both on and off the racetrack.

Porsche has announced that the new, more advanced 911 GT3 R Hybrid will enter the Nürburgring 24 hour race on June 25th, 2011. The focus of this latest edition has been to improve efficiency through the targeted optimization of hybrid components, which had the added bonus of a 20 percent reduction in weight. The intent is to achieve the same lap times as the previous edition while improving fuel efficiency.

Engineered exclusively for racing, the 911 GT3 R Hybrid integrates two 75 kilowatt (an improvement from the previous 60 kW) electric motors that drive the front wheels and supplements the 4-liter – depending on the balance of performance classification – approximately 470-hp, six cylinder Boxer engine at the rear.

The electric flywheel accumulator, that drives the electric motors, is now housed with the other hybrid components in a carbon fiber safety cell on the passenger side. With the rotor spinning up to 40,000 rpm, it mechanically stores electrical energy and this energy is available for bursts of multiple seconds at a time. Drivers have almost an additional 200-hp available on demand for short bursts, like when the GT3 R Hybrid is overtaking or accelerating out of a turn.

The new GT3 R Hybrid also received a minor external facelift. With optimization to the hybrid system’s high voltage components, Porsche was able to remove the large louvers in the front of the rear fenders. The results were a double-win situation–a reduction in drag and improved fuel efficiency. Altogether, the overall weight of the vehicle decreased from 1,350 kg to 1,300 kg.

“We’ve collected a great deal of information from our races on the Nürburgring, at the ALMS race at Road Atlanta, as well as from the ILMC race on China’s Zhuhai circuit. The data was invaluable for the further development of our racing laboratory,” says Hartmut Kristen, head of Porsche motorsport.
“The emphasis of our work was on improving efficiency. That means we want to keep the lap times consistent with 2010 but use less energy, hence less fuel. In this way, we support future developments of road-going, sporting hybrid vehicles.”
