But just below timberline, vehicles encounter a long series of steep switchbacks called the “Ws,” which include a series of unforgiving “blue-sky” corners that can catapult an out-of-control racecar over 1,000-foot embankments to the road below. The lower portion is basic road-course driving. The race begins at 9,400 feet altitude and drivers must artfully master each of Pikes Peak’s 156 corners on their way to the finish line at the 14,110-foot summit. The weather can change from warm and sunny at the bottom to freezing cold with blowing snow at the top. The race is challenging, to say the least. Electric motors produce full torque off the corners and there’s no power loss at altitude, which makes an electric motor the ideal propulsion unit for high-altitude hill-climb racing applications ( see photo #1). R reportedly uses a 43-kilowatt hour battery to supply two electric motors, which produce a combined output of 500 kilowatts (about 680 brake horsepower and 479 foot-pounds of torque), which will accelerate the 2,425-pound all-wheel-drive car from 0-60 mph in 2.25 seconds and to a top speed of 150 mph. R prototype now holds the modified electric vehicle and unlimited class records at Pikes Peak. Photo 1: Coming at you - on battery power, that is. R prototype as the car to beat at the Jhill climb event. Slashing the unlimited class record by 16 seconds, Dumas firmly established the I.D. More to the point, three-time Pikes Peak class winner and world-class driver Romaine Dumas’ new modified electric record of 7 minutes, 57.148 seconds also beats the unlimited class record of 8 minutes, 13.378 seconds set by World Rally Champion Sebastien Loeb driving a 3.2-liter, twin-turbocharged car in 2013.
