It's a track car designed for road races, not drag racing. This car is essentially meant to be a jack of all trades, whereas top fuel dragsters are probably the most purpose built car of all time.
>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.
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.

Effectively a big CVT with no moving parts.

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
