THE CARS

Porsche 911 Carrera S

The 911 has been the world's best-selling sports car for decades. In 2015, the new generation arrived to further extend this lead. With innovative turbo flat engines, an advanced chassis with an even greater spread between performance and comfort it is exceedingly well-equipped for this. Thanks to more than four decades of experience with turbo engines – in both motor racing and production sports cars – the new engines in the 911 Carrera S offer improved performance, even more emotional driving pleasure and higher efficiency. 420 hp (309 kW) of power at the rear are waiting to be unleashed and converted into sporty propulsion. The greater power of the 911 Carrera S results from turbochargers with modified compressors, a specific exhaust system and tuned engine management. The new 911 also boasts impressive performance: The 911 Carrera S with Porsche-Doppelkupplung (PDK) and Sport Chrono Package performs its showcase discipline – the sprint from zero to 100 km/h – in just 3.9 seconds. This means that it is the first 911 in the Carrera family to undercut the magic four second mark. And the top speed has also increased further: the 911 Carrera S now reaches a mind-blowing 308 km/h. All in all, the 911 Carrera S again sets the benchmark for driving dynamics of all-round sports cars, further increasing the spread between everyday comfort and circuit performance.

Porsche 918 Spyder

The 918 Spyder embodies the essence of the Porsche idea: it combines pedigree motor racing technology with excellent everyday utility, and maximum performance with minimum consumption.
The 918 Spyder reveals its close links to motorsport in a variety of ways. It has been designed, developed and produced by Porsche engineers who build race cars, in cooperation with series production specialists. A great deal of insight gained from the development of Porsche race cars for the 24 hours race in Le Mans in 2014 was thus integrated into the 918 Spyder – and vice versa. Also, many parts of the super sports car come from manufacturers who have a proven record as suppliers for motorsport vehicles.
The main source of propulsion is the 4.6-litre, eight cylinder engine that produces 608 hp (447 kW) of power. The engine is derived directly from the power unit of the successful RS Spyder, which explains why it can deliver engine speeds of up to 9,150 rpm. The V8 engine is coupled to the hybrid module, which comprises a 115 kW electric motor and a decoupler that serves as the connection with the combustion engine. An additional electric motor with 95 kW drives the front axle. Because of its parallel hybrid configuration, the 918 Spyder can be powered at the rear axle either individually by the combustion engine or electric motors or via both drives jointly, thus giving it a total power of 887 hp (652 kW). The sprint from 0 to 100 km/h is performed within 2.6 seconds, and the top speed is reached at 345 km/h.
The car has an unladen weight of approximately 1,640 kg, an excellent low weight for a hybrid vehicle of this performance class. The drivetrain components and all components weighing over 50 kg are located as low and as centrally as possible within the vehicle. This results in a slightly rear end biased axle load distribution of 57 per cent on the rear axle and 43 per cent on the front axle, combined with an extremely low centre of gravity at approximately the height of the wheel hubs, which is ideal for driving dynamics.
All of this serves to give the 918 Spyder a superior performance on the racetrack. As the first vehicle to boast global road homologation, the 918 Spyder has conquered the 20.6-kilometre lap around the Nürburgring Nordschleife in less than seven minutes. Achieving a time of exactly six minutes and 57 seconds, the super sportscar shaved an incredible 14 seconds off the previous record.
