Porsche 911 Hybrid - attribution Automotive Rhythms

From the racetrack to the road, this might be the story of the Porsche 911 GT3 R Hybrid race car that was unveiled back in March at the Geneva Motor Show.

And this is not just another rumor, as the spies caught a prototype near Nurburgring, in Germany, that had a number of telltale signs that under its body it is not an ordinary 911. Regarding the 911 GT3 Hybrid R, this race car already showed that it can write a page of history, as it scored a podium finish in its second appearance in the Nurburgring Endurance Series. Regarding its engine, the car uses a newly-developed 480 hp 4.0-liter flat-six engine but also two electric motors (60 kW each) featured on the front axle. It is expected that the road version car will carry the same technology becoming one of the fastest Porsche cars but also the most fuel-efficient then it will hit the dealerships in 2012.

New York 2010: Porsche Cayenne S Hybrid

Reply

 

Porsche showcased at the New York Auto Show, the next generation Cayenne sport utility vehicle. With this occasion, the company is also presenting its new high-tech gas-electric hybrid model, a version which will register higher performance using less fuel and improving emissions.

The new North American Cayenne range offers 4 models- the 2011 Cayenne, Cayenne S, Cayenne Turbo and the Cayenne S Hybrid. The S and Turbo models go on sale in July, with the 2011 Cayenne and Cayenne S Hybrid hitting the market by this fall. The new advanced S Hybrid is powered by a combination of parallel systems, a supercharged V6 combustion engine and an electric motor, accumulating a power output of 380 hp. Continued after the jump!

Using this combination, the S Hybrid will always perform in achieving maximum efficiency. The car shows lots of flexibility as the driver can choose to drive either with one of the units either with both of them, as they are connected by a decoupling clutch.

The new hybrid can be driven on short distance only on electric power, meaning 0 emissions and noise up to 60km/h.

This version of Porsche’s popular mid-engine sports car is the lightest Porsche available is on sale now with an MSRP of $61,200, weighing only 2,811 lbs.

 

 

Porsche Cayenne S Hybrid

At the 2010 New York Auto Show will be where the all-new 2011 Porsche Cayenne will make its North American debut. What this means is that this technically advanced Cayenne S Hybrid will arrive in local showrooms before the year ends.

Typically, the situation had been that the US doesn’t get the ‘niche’ models like hybrids and diesels. US fans who were waiting for the Cayenne Diesel to arrive will be disappointed as there are still no plans for its arrival but maybe the almost-as-efficient Cayenne S Hybrid will be sufficient. There’s no doubt though that the Cayenne S Hybrid is the highlight of the new 2011 Porsche Cayenne lineup.

The model has a sophisticated parallel hybrid drive system that combines a supercharged 333hp 3.0-liter gasoline V-6 with a 47hp electric motor running on lithium-ion batteries. This means that the engine is not much different from a V-8. It is capable of delivering 380hp and 427 pound-feet of torque, which is available from a low 1,000 rpm.

Driving conditions would determine if the supercharged V-6 or electric motor operates independently or together. The two drive units are connected by a decoupling clutch. To make the transition among various driving modes seamless, a hybrid controller coordinates their interaction and electronic management of the clutch.

Similar to most hybrids, the Cayenne S Hybrid can go short distances on electric power alone. It can go as fast as nearly 40 mph. Of course, these cars don’t have emissions and noise. The Cayenne S Hybrid also has this unique ability to cruise at high speeds on electric power alone. Drag forces exerted by the engine are eliminated because its gasoline engine can be completely switched off and disengaged from the drivetrain at speeds of up to 97 mph.

More Details Revealed About Porsche Cayene Hybrid

The official details of the new Porsche Cayene Hybrid were revealead, thanks to Autocar magazine, who were lucky enough to test the new vehicle from the German manufacturer.

The new hybrid SUV will carry the supercharged 3.0-litre V6 petrol engine from Audi, capable to deliver 325bhp and 324lb ft and assisted by an electric motor delivering 38kW and 184lb ft. The battery comes mounted under the boot floor and can provide enough electricity for the car to run on electric power alone for 1.2 miles and at under 31mph. Continued after the jump!

According to our sources, the new Cayenne S Hybrid and Cayenne S Diesel, unlike petrol-engined versions of the new Cayenne which will use a multi-plate clutch to apportion drive, will use a lighter and more easily packaged Torsen four-wheel drive system similar to the one used on the popular Audi Q7.

Regarding the performances of the hybrid SUV, this will hit 62 mph in just 6.5sec and will have a towing capacity of up to 3500kg.

The Porsche Cayenne Hybrid will also deliver an impressive fuel consumption of 34.5 mpg and 193g/km CO2 emissions. 

Porsche Cayenne CO2ncept-10%

Schaeffler Group revealed today its new CO2ncept-10% vehicle, a new car based on the Porsche Cayenne which will be presented at the ATZ/MTZ Congress focusing on “Friction Reduction in the Powertrain” to be held on December 9-10 in Esslingen.

What is so special about this car? Well, it appears that the CO2ncept-10% was developed by Porsche and the Schaeffler Group and involves the use of novel and optimized components in order to achieve a reduction of 10% in fuel consumption and CO2 emissions. The car you see in the photos is a Porsche Cayenne with a V8 engine, but the engine, according to Schaeffler, accounts for 5.8% of the optimization of fuel consumption and the associated CO2 emissions.

These results (almost 4.1%) were obtained by modifying the VarioCam Plus valve control system through the replacement of hydraulic cam phasers by electromechanical cam phasers and by using of optimized switching tappets on the intake side. The rest of 1.7% was obtained due to the minimized frictional loss through the cross-system optimization of components in the valve train, belt drive and chain drive. Another 1.1% was obtained using double-row angular contact ball bearings installed in the front and rear axle differentials, replacing the used tapered roller bearings and reduce frictional resistance considerably.

The chassis also helped the manufacturer to reduce the fuel consumption by replacing the hydraulic roll stabilizer with an electromechanically controlled equivalent and using smooth-running wheel bearings brought about a consumption benefit of 3.2%.“As in the case of the cam phasers, the electrically operated components make such an important contribution because they require energy only when their operation is requested. In hydraulically controlled systems, the pumps have to maintain pressure permanently, resulting in much higher energy requirements.” explains Dr. Robert Plank, Manager of Corporate Engineering for the Schaeffler Group.
