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.By Csaba Daradics

A Porsche confirmou oficialmente a fabricação do Cajun, na linha da Porche ele fica abaixo do Cayenne. O Cajun será produzido em Leipzig, na Alemanha, junto com o Cayenne e o Panamera.
The latest addition to the Panamera family makes use of the same powertrain found on the Cayenne hybrid mating a 333HP 3.0-liter supercharged V6 sourced from Audi to a 47 hp (34 kW) electric motor for a combined output of 380HP. Both motors are capable of powering the Panamera S Hybrid either alone or in combination, while the electric motor also operates both as a generator and a starter. The electric motor is fed by a nickel metal hydride battery (NiMh) where the electrical energy recovered from braking and driving is stored. Power is transferred to the rear wheels by the familiar eight-speed Tiptronic S. Porsche says the Panamera S Hybrid can complete the standard sprint to 100 km/h in 6.0 seconds (0-60mph in 5.8"), and reach a top speed at 270 km/h (168 mph). The range in purely electric mode is approximately two kilometres (1.24 miles) with electric driving possible up to 85 km/h (53 mph), depending on the driving situation. When fitted with the optional lower-rolling resistance all-season tires from Michelin, the Panamera hybrid consumes on average 6.8 lt/100 km (34.6 mpg US.) with CO2 emissions of 159 g/km. With the standard tires, the hybrid model returns 7.1 lt/100 km (33.1 mpg US) with 167 g/km of CO2. All Panamera S Hybrid models will come fitted as standard with the adaptive air suspension including the adaptive shock-absorber system with PASM, as well as a bespoke display concept that provides the driver with relevant information about the vehicle’s specific hybrid driving status. The Panamera S Hybrid will enter the European market in June 2011 and cost €106,185 in Germany, including VAT and country-specific equipment, while sales in the States will start a little bit later in 2011 at a base suggested retail price of $95,000 excluding destination (€70,320).
