Volkswagen has revealed the 671bhp ID R Pikes Peak electric-powered prototype that it will use on the Pikes Peak International Hill Climb in June.
The machine, which has been designed solely for the 12.42-mile, 156-turn Colorado hill climb, features two electric motors that combine to produce permanent four-wheel-drive and offer 470lb ft of torque. The ID R Pikes Peak weight 'less than' 1100kg, including driver Roman Dumas, with Volkswagen claiming a 0-62mph time of 2.25 seconds and a top speed of 149mph.
The one-off racer is 5200mm long, 2350mm wide and 1200mm high, with a wheelbase of 2850mm. It features double wishbone suspension. The chassis is built around the safety monocoque from a Norma sports prototype - which Dumas has used to win Pikes Peak for the last three years, with Volkswagen developing a closed-cockpit sports prototype-style design. The lithium-ion batteries are mounted in the floor of the car, with a large rear wing and other aerodynamic parts designed to ensure maximum grip despite the high altitudes.
Volkswagen is gearing up to launch the ID range of electric road cars starting in 2019. The firm’s development boss, Frank Welsch, described the Pikes Peak event as a “real acid test” for the firm’s electric programme.
“Customers have always benefitted from the findings made in motorsport, and we expect to take these findings and use them as a valuable impetus for the development of future ID models,” said Welsch.
Volkswagen says that the focus of the ID R Pikes Peak is not on outright performance, but on balancing energy capacity and weight.
The machine is powered by lithium-ion batteries developed in collaboration with Volkswagen’s battery plant in Braunschweig, Germany, although the focus is on ensuring the highest possible power output for the run up the Colorado mountain, rather than outright range. Volkswagen says that around 20% of the energy used by the ID R Pikes Peak will be created using energy recovery during braking on the course. A fast-charging system will allow the batteries to be charged in around 30 minutes.
The ID R Pikes Peak has been developed by Volkswagen's motorsport division. Sven Smeets, the firm's motorsport chief, hinted that it could be the first of several EV projects, saying: “As with the Volkswagen brand’s production vehicles, fully electric racing cars will also play an increasingly important role for us in the future.”
The ID R Pikes Peak was launched at the Pole Mecanique circuit in Ales, France, shortly before starting a test programme there. Because the Pikes Peak course is a public road, participants are unable to test there ahead of the event – and even in official practice only get to run on short sections. The ID R Pikes Peak will run in the top Unlimited Division, which only stipulates that cars meet certain safety requirements.
Volkswagen is targeting the record for an electric car at Pikes Peak of 8min 57.118secs by Rhys Millen in a Drive e0 PP100 in 2016. That car featured six electric motors and offered peak power of 1596bhp.
The outright Pikes Peak course record of 8min 13.878secs was set by Sebastien Loeb in the Peugeot 208 T16 Pikes Peak in 2013.
The Pikes Peak International Hill Climb, which takes place on June 24 this year, is regarded as one of the toughest hill climbs in the world. As well as the 156 turns on its 12.42-mile (19.9 km) route, competitors must also cope with the elevation: the start line is 9390 feet above sea level and rises 4720ft to the finish at a height of 14,110ft. The course gradient averages 7.2%.
Volkswagen previously competed at Pikes Peak between 1985 and 1987, with Jochi Kleint running a twin-engined Golf. That car had turbocharged 1.8-litre engines driving each axle, giving a peak output of 652hp. Kleint was the fastest driver to the halfway point in 1987 but retired with a suspension joint failure less than a mile from the finish.
