Porsche’s decades of racing history are headlined by a record 19 overall wins at Le Mans, but most Porsche racing cars are spec racers. 4400 of those prolific 911 GT3 Cup cars have been built since the first Carrera Cup category kicked off 31 years ago. The near future of that category is the new 911 GT3 Cup, but the world is electrifying fast and Porsche knows its beloved flat sixes will not be around forever. Enter the Mission R concept.
The all-electric Mission R delivers what Porsche describes as “the same lap time performance” as a current GT3 Cup, but it finds that speed in a very different way. In its all-out qualifying trim, two sets of electric motors deliver 429 horsepower to the front wheels and 644 horsepower to the rear wheels for a combined 1073 horsepower. Porsche says the car will achieve a top speed of 186 MPH and reach 60 MPH in under 2.5 seconds. That output falls to 671 hp in race trim, but the smaller output greatly increases available track time.
An 80 kh battery allows the car to race for 30 to 45 minutes at a time, long enough for a current Carrera Cup race but not quite long enough for a serious endurance racing future. A new 900-volt fast charge system allows the car to reach 80% of that capacity in just 15 minutes, a number that will be the key to unlocking the car’s ability to run both long track days and full race weekends in competition.
