The Porsche 919 Hybrid
The Porsche 919 Hybrid has been widely reworked for the 2017 championship. 60 to 70 per cent of the Le Mans prototype’s components are new developments. This especially concerns the areas of aerodynamics, chassis and combustion engine. However, the power train in principle remains the same. The innovative hybrid race car develops a system power of around 900 HP (662 kW) that comes from a compact two-litre turbo charged V4-cylinder (nearly 500 PS/368 kW) and two different energy recovery systems – brake energy from the front axle combined with exhaust energy. The combustion engine drives the rear axle while the electro motor boosts the front axle with an output of more than 400 PS (294 kW). The electrical energy that comes from the front brakes and the exhaust system is temporarily stored in a liquid-cooled lithium ion battery.
The Porsche 911 RSR
The 911 RSR, which celebrated its race debut at the Daytona 24-hour classic in January, is a completely new development: the suspension, body structure, aerodynamic concept, engine and transmission have all been designed in Weissach from scratch. Depending on the size of the restrictor, the motor, which is now positioned in front of the rear axle, puts out around 375 kW (510 hp). Thanks to the particularly large rear diffuser combined with a top-mounted rear wing, the level of downforce and the aerodynamic efficiency were significantly improved. The 911 RSR, whose predecessor model claimed a double victory at Le Mans in 2013, tackles the second 24-hour race of its maiden season again sporting the further developed factory design with the primary colours white, red and black.
