Virtually something goes on the weekly Friday Night time Drags occasion organized by the Texas Motor Speedway. You’ll be able to enter to race in a Lamborghini Aventador S, in a basic Mini, or something in between so long as you comply with primary guidelines like sporting a helmet — and never displaying up on monitor day in an electrical automobile. The venue’s house owners not too long ago banned EVs from competing.
The Texas Motor Speedway harassed that it’s not afraid that electrical automobiles will beat gasoline-powered fashions. It could welcome the competitors between, say, a Tesla Mannequin S and a Mercedes-AMG E63. It determined to cease permitting electrical automobiles onto its drag strip attributable to security considerations. If one catches hearth, which isn’t unheard of, the Speedway doesn’t have the gear required to place it out. Gasoline- and diesel-powered automobiles go up in flames too, however these fires are simpler to extinguish.
“The explanation for the exclusion is, within the occasion of a crash and doable ensuing hearth, our emergency autos at the moment don’t carry the precise gear required to suppress EV fires. As I’m certain you’re conscious, standard extinguishers are of no use in combating a lithium-ion battery hearth,” wrote Texas Motor Speedway spokesman David Hart in an e mail despatched to Tesla fan web site Teslarati.
Fundamental chemistry explains the distinction between an electrical automobile hearth and a piston-powered automobile hearth. The chemical substances contained inside a regular hearth extinguisher are ineffective in opposition to a burning lithium-ion battery pack. The perfect resolution is to both use hundreds of gallons of water, in line with Autoblog, or to let the automobile burn till each a part of it has been consumed.
Neither choice is right, particularly on a racetrack. There are different dangers, too. Electrical automobiles generally re-ignite many hours after the fireplace has been put out, and the high-voltage system provides one other bullet level to the record of life-threatening hazards first responders must consider. Coping with a burning electrical automobile requires a substantial amount of preparation.
Digital Traits has reached out to the Texas Motor Speedway to seek out out whether or not it plans to spend money on the gear wanted to extinguish a burning electrical automobile. We’ll replace this story once we hear again.
