The McMurtry Speirling is the fastest car of any type to conquer the hillclimb, but there was already one EV that beat every other car up the hill.
This is not the only record held by an EV at Goodwood.
This means the McMurtry has more downforce at 0mph than an F1 car produces even at 150mph. The McMurtry Speirling produces more than 2,000kg of downforce (on a 1,000kg vehicle), and unlike traditional aerodynamic surfaces, this doesn’t scale with speed – it’s available at any speed due to the fan’s operation. Later, Brabham brought a fan car to F1 in 1978 and won its first race by a huge margin, but the concept was also immediately banned from competition there. As a result, fan cars can go faster with less aerodynamic drag, and can take corners at higher speeds, than other vehicles that rely on traditional aerodynamic surfaces.įan cars first appeared in motorsport in the 1970s with the Chaparral 2J, a boxy monstrosity (which also ran at Goodwood) which competed in 1970 but was outlawed due to its obscene aerodynamic advantages. This results in incredibly efficient downforce, without the downsides of drag that a large spoiler or other aerodynamic surface often creates. Well, McMurtry’s new recordholder uses a fully electric powertrain just like VW’s entry did, but adds an additional technology that motorsport hasn’t seen for quite a while: it’s a “fan car.”įan cars work by having low side skirts and a fan underneath the car which draws air up and pushes it out of the rear of the car, creating a vacuum underneath the car. You may ask yourself: why is it so loud? Aren’t EVs supposed to be quiet? And what’s that “exhaust” coming out the back?
