With the Cayenne S Hybrid, Porsche swim with the hybrid shaft at the top or sailing. Because the Zuffenhausen want as long distance glide without engine.

2010, the first Porsche Cayenne will come with hybrid drive on the market. He is the next consumption-reducing innovation, with the Stuttgart their SUV range will wean the excessive drinking habits.

Basis for the hybrid powertrain is a V6 petrol engine from Audi stocks. The aggregate three-liter, direct injection and supercharging, Audi has developed just last year. While it makes the brand with the four rings from 213 to 245 kilowatts, it offers only Porsche with 245 kilowatts of power and 440 newton meters. The charge by riemengetriebenem compressor means two things. By the power requirements of the compressor in this technique, the fuel consumption in comparison with an equally strong engine with a turbocharger is not quite as high. However ensures the compressor in the lower speed ranges for much more agility. "We use the electric motor and the battery capacity for mainly electric starting and steady cruising at higher speeds," says Dr.-Ing. Michael Head, Project Manager for the Cayenne Hybrid.

The 38-kilowatt synchronous electric motor from Bosch, together with the clutch only 15 inches long and fits relatively easily between the V6 and the eight-speed torque converter automatic by Aisin. This configuration allows the first three normal modes: conventional drive with a combustion engine, accelerating with combustion engine and electric motor (boosting) and driving with only the electric motor. There is also a control strategy for converting kinetic energy into electrical energy and subsequent storage in the nickel-metal hydride battery (regeneration) by Sanyo and the stop-start function.
Two other modes

The engineers have the Cayenne Hybrid but still planted two additional modes that make up the majority of the approximately 2.5 liters less fuel consumption compared to conventional Cayenne with VR6 engine: the load point shift modes and sailing. When the load point of the V6 engine, for example, is used not only for propulsion, it also simultaneously charges the battery. This higher load, he works in map areas that are more fuel efficient.

Solely by the load point displacement and further optimization of engine measures implemented 44 percent of under Porsche Cayenne Hybrid (8.9 liters per 100 kilometers, 210 grams of CO2 per kilometer) compared to a conventional Cayenne with VR6 engine (12.4 liters, 294 grams CO2) emissions. Other measures include the modern V6 engine, demand-controlled ancillary components, and an eight-speed automatic transmission with torque converter lockup instead of the current six-speed automatic. Using the new dual clutch transmission have been discarded because the automatic transmission, especially when starting with a trailer is better.

Electric driving contributes to an additional 26 percent of under-spending. Porsche concentrates on the electric motor operating mainly on purely electrically powered driving. Less on the supportive boost function during acceleration because the supercharged V6 compressor already has a good torque curve. The Cayenne Hybrid will be driven in large areas with low load demand, or only with the electric motor. In addition, heres the clutch between the combustion engine and electric motor into play. It decouples the engine from the rest anyway dormant drivetrain, preventing unnecessary braking drag torques. The first German production hybrid Mercedes-Benz S 400 is still the way to a rigid engine-transmission connection to the market.

Reactivation of the internal combustion engine in 0.3 seconds

Calls to the driver more torque and the energy storage is exhausted, the combustion engine is in less than 0.3 seconds is coupled to the drive train, and from the electric motor is started. "The sails are phases in the current testbed possible up to a speed of 138 kilometers per hour, to the start of this mode should be extended until at 157 pace," said Head. Overall, the process developed by Bosch hybrid management for the complex control strategy more than 20,000 parameters. For comparison, a conventional motor control comes from with 6,000 parameters.

The introduction of the sail and their expansion phase up to a brisk highway speeds makes sense, since the typical driving profile of the Cayenne contains more intercity and highway routes and smaller urban units with stop-and-go traffic.

The sailing mode, the Cayenne ruled on a splash and sail around Stuttgart already very well when the drivers foot on the accelerator and curbing the flow of traffic as evenly as possible about his death. The reactivation of the engine is almost imperceptible to the driver. The hybrid Cayenne consumed on the average driving profile approximated circuit just over nine liters per kilometer. Remarkably, after all he is about 170 kilograms heavier than his brother, with series six-cylinder. Since the electric motor in addition to the rather moderate power of 38 kW but develops 285 Nm of torque, comply with the performance and acceleration values ​​which the larger V8 engine. This approval, however, the cycle 15 liters of petrol per 100 kilometers, 355 grams of CO2.

René Rast won the Double

In 2012, René Rast was unstoppable in the Porsche Carrera Cup. Motorsport-Magazin.com look back on the 2012 season.

In the last five years, René Rast has scored five Porsche titles, this year he won alongside the Porsche Carrera Cup, even the Supercup. Six wins from 17 races was the balance in the last season - and won the championship was only shortly before the finish decided the finale at Hockenheim. Even Sean Edwards drove a great season, brought five wins and in the end only nine points behind catch landed in second place.

The start of the year could hardly have gone better for rest. From third on the grid, he took the season opener at Hockenheim a victory the next day and drove right back to third place. Even if it is in qualifying, such as at the Nürburgring with starting number ten, not as required, ran snap collected at the end points. Only in the last race of the season, as the title was in the bag, rest it afforded a clear round.

"Win for both titles in one year, of course, is an absolute highlight of my career, I am sure it was Carrera Cup champion in the 2008 season and last three-time champion of the Supercup -. But grabbed the extremely difficult double to have is a damn good feeling. More can not be achieved in the Porsche brand trophy "catch cheered after the successful year.

Nicki Thiim to rotate

About a lack of competition, but he could not complain. Besides Sean Edwards mingled the Frenchman Kevin Estre the front line, at the Red Bull Ring, he even took over the overall lead, which he shortly afterwards after a failure at the Norisring, but had to give back the same.

A strong second half of the season showed Nicki Thiim. The young Dane turned on by a powerful double-zero in Nuremberg and drove in six of the last eight races on the podium. That was enough to get it in the end still create up to third in the championship.

The Porsche Panamera Sport Turismo is a glimpse into the future of the sports car maker: latest hybrid technology in trendy shooting brake guise. (Porsche)

New rear and stronger hybrid: Porsche shows in Paris a Panamera, which is visually convincing as drive terms. The concept vehicle is above all a taste test of what would offer the sports car maker in the future.

This is Porsches look into the future: The study Turismo Panamera Sport is not just a shooting brake but also has a hybrid drive. At the Paris Motor Show, the Zuffenhausen now presented before the 4.95 meter long Panamera Sport Turismo. Eye-catching is the large tailgate, which resolves the crunchy end of the car. The concept vehicle is generous with power: 306 kW / 416 PS are available in the peaks. Nevertheless it is of purely electrically powered car can reach speeds of up to 130 km / h. A range of over 30 km is thus possible and also scores when it comes to the concept of consumption: At 3.5 liters per 100 kilometers with a CO2 emission of less than 82 grams per kilometer would be the Sport Turismo sparingly.

Visually striking is smooth on the sides of body. Porsche eliminated from the study on conventional mirrors and relies entirely on futuristic two cameras in the side air outlets. The images of the rider gets on a display in the cockpit. Only the word "e-hybrid", which refers to the drive concept differs from the flawless profile.

For a Shooting Brake characteristic is the tail, which is designed as compared to the serial Panamera scratch. In the form, the representatives of value on three dimensions: both the rear lights in LED technology and the taillight strip with the words are formed. An adaptive carbon rear spoiler rounds out the rear view. It forms the roof edge and provides in addition to the sporty look also for improved downforce.

The need for the hybrid drive battery case is made of aluminum and sits under the boot floor, which consists of elektrochromatischem glass. By pressing a button, the glass is a view of the illuminated in Acidgreen energy source.
Whopping 315 kW system power

The electric motor in the Turismo Sport offers around 70 kW / 95 PS, doubling the capacity of the current Porsche hybrid drive. A supercharged three-liter V6 engine, the system adds an additional 245 kW / 333 PS. In combination of both drives the accelerated study in less than six seconds from zero to 100 km / h

The electric drive is the favored mode of operation. A button on the steering wheel, the driver disables this. With the e-batch mode it reaches the targeted increase in the charge state of the high-voltage battery. This is particularly useful if a highway driving route follows a city that should be purely electrically and without local emissions. Also, the plug-in-charge of the Panamera Sport Turismo is planned. In only 2.5 hours to take place this.

The interior continues the futuristic orientation. A large color display replaces the traditional instruments. The driver can access all information on the display and can be displayed as needed. Two additional displays in the form of tubes, for example, inform about hybrid-specific driving modes, such as the pure electric driving. Multitouch functionality allows all vehicle displays and control functions operate like automatic climate control, seat adjustment, light, rear view camera and the functions of the Porsche Communication Management.
