Why would an EV incorporate tech from top _fuel_ dragsters? What tech besides tyres and aero would they adopt?

  Flames, smoke, and the occasional explosion perhaps?

  I'm pretty sure top fuel dragsters are all about tires and aero and only inconsequentially the power source. It might be an easy problem to solve acceleration to 100km/hr since you don't have to carry batteries to go an entire 1/4 mile

  not many other vehicles have the ability to transfer >6000ft/lbs of torque down to the pavement to be able to accelerate at 5gs

    not to mention each run down the track is a stunning controlled demolition of the engine

  The video shows it using kart tyres, and I would be interested to see what it would do with proper drag radials, since they change shape quite a lot during a launch: https://www.caranddriver.com/features/columns/a26089565/drag-racing-tires-explainer/ https://www.caranddriver.com/features/columns/a26089565/drag... >The massive torque channeled through the rear axle shifts the load of the car rearward and tries to twist the tire on its 16-inch beadlock rim. The sidewalls wrinkle as the tire—generally running between 6.0 and 10.0 psi of pressure—shrinks in radius by more than six inches and the tread effectively balls up at the front of the contact patch. That compression of the tire expands the contact patch to almost 250 square inches—larger than two side-by-side sheets of 8.5-by-11-inch paper. The compression of the tire also means that the final-drive ratio is effectively shortened for a harder launch. By the time the tire has released the torque stored in its wrinkled sidewalls and tread and grown back to its original size, the Top Fueler is already pulling more than 4.00 g's of acceleration. >After the car launches, inertia grows the tire to as much as 38 inches in diameter, simultaneously lengthening and narrowing the contact patch. This effectively lets the final-drive ratio grow taller for higher speeds and reduces rolling resistance as the vehicle hits terminal velocity. Effectively a big CVT with no moving parts.

  Wheel spinning and burning rubber? Electrics going for maximum acceleration usually don't do that, because once the wheel is spinning relative to the pavement, friction is reduced and there's less acceleration. Watch videos of Teslas in launch mode.

    > burning rubber The burning rubber is to heat the tyre rubber to get the rubber to maximum adhesion, just before doing the run. > Wheel spinning Maximum acceleration occurs with some tyre slip - spinning a little but not a lot: https://www.researchgate.net/profile/Masayoshi-Tomizuka/publication/46439292/figure/fig1/AS:668912408612881@1536492554746/Adhesion-coefficient-vs-wheel-slip-acceleration.png https://www.researchgate.net/profile/Masayoshi-Tomizuka/publ... https://www.google.co.nz/search?q=tire+adhesion+versus+slip+graph https://www.google.co.nz/search?q=tire+adhesion+versus+slip+... I am guessing you know that, but just clarifying.

    Did you watch the video? They do exactly that.
