McMurtry Speirling warps time, resets Goodwood Hill Climb record
At the 2021 Goodwood Festival of Speed, the British company McMurtry launches Speirling, a tiny (only 126 inches long) but powerful electric car that eliminates obstructing aerodynamic features with a fan-powered ground-effect system that generates downforce. We’re talking about the ability to generate more than 4,400 pounds (up from 1,100 pounds ago) of downforce when stalled.
But does it really provide the right direction? The answer is yes in a resounding way as we discovered at the Goodwood Festival of Speed in the UK last weekend, where McMurtry took part in the event’s Sunday Shootout hill climb, not just winning won but also won the record.
With former Formula 1 driver Max Chilton, now Early development driver for Speirling, behind the wheel, the small Batmobile launched up the hill in just 39.08 seconds. The previous record for a 1.16-mile hill climb around the grounds of Goodwood House was 39.9 seconds set in 2019 by Romain Dumas, behind the wheel of Volkswagen ID.R 670 hp special time attack. Considering the brevity of the track, the gap between the two times is nothing short of amazing.
What makes Speirling, as a technology showman, so quick is the combination of high horsepower, low weight, low drag and of course amazing downforce, with second power. two larger than what an F1 car produces at up to 150 mph. The powertrain consists of a pair of electric motors that drive the rear wheels and power those motors with a 60 kilowatt-hour battery pack.
McMurtry doesn’t say how powerful the Speirling is but claims the car has approximately one horsepower for every 2.2 pounds of weight. The vehicle’s weight is claimed to be under 2,200 pounds.
Performance claims include a 0-60 mph time of under 1.5 seconds and a top speed of 150 mph, the latter of which is limited due to the transmission setup McMurtry uses for hill climbing. Usually top speed is over 200 mph.
“The largely continuous downforce is an innovative feature to exploit as a driver,” Chilton said before the run. “It’s very different from what I’ve driven in F1 and IndyCar, and this year’s testing has required me to adapt my driving style to maximize performance.”
