Porsche is previewing a 1,073bhp advanced battery electric racing car at the 2021 Munich Auto Show. The low-profile carbon fiber coupe concept, known as the Mission R, is said to provide solid indications as to the styling of an upcoming electric-powered version of the third-generation 718 Cayman.
Scheduled for sale to customers through Porsche’s Motorsport division from 2025, the all-wheel-drive Mission R was developed as a zero-emission alternative to the Porsche 911 GT3 Cup and GT3 R. Its dual-electric-motor powertrain offers two different System outputs, with 603 hp available in standard race mode and 1,073 hp available in a special qualifying mode.
The electric motor mounted at the front of the concept car produces a maximum power of 429 hp, while the electric motor mounted at the rear produces 644 hp.
Driving is provided by a single-speed gearbox instead of the two-speed unit of the Porsche Taycan, which shares its electric motors with the new concept.
According to Porsche, the Mission R shows a 0-62 mph (100 km / h) time in under 2.5 seconds and can reach a top speed of 186 mph (300 km / h).
The electric motors are combined with a 900V 80 kWh battery designed to provide the Porsche with around 40 minutes of running time. The lithium-ion unit weighs 330 lbs. (150 kg) and is mounted behind the cab in the same position as the combustion engine of the existing 718 Cayman.
The high voltage of the battery allows charging up to 340 kW, allowing a charge of 5% to 80% in 15 minutes, according to the German automaker. The front-mounted electric motor also acts as a generator, recovering kinetic energy during braking.
Porsche says it aims to provide the customer version of the Mission R with a curb weight of around 3,300 lbs. (1,500 kilograms). Among the weight saving features is a newly developed carbon fiber roll bar. Instead of being mounted inside the cabin, it uses an exoskeleton design to be part of the roof.
Current FIA motorsport regulations require racing cars to be fitted with steel roll cages, although Porsche says there are signs this could change before continuing with limited production on the Mission. R.
The interior follows the design of modern racing cars, with a carbon fiber seat, digital instruments and a steering wheel housing numerous controls.
The Mission R measures 5.1 inches. (130 mm) shorter, 8.3 inches. (212 mm) wider and 2.0 inches. (48mm) lower than today’s 718 Cayman at 170.3 inches. (4,326 mm) in length, 78.3 inches. (1,990 mm) wide and 46.9 inches. (1,191 mm) high.
Porsche Design Director Michael Mauer alludes to the styling similarities between the new racing car and the new generation 718 Cayman: “Down to the waist there are echoes of a future production model.
Due in 2022, the new 718 Cayman is expected to be sold with the choice of combustion engines or battery-powered electric powertrains.
