Why This Koenigsegg Doesn't Have A Transmission
Koenigsegg isn't crazy, they left out the transmission for a very smart reason
When power levels start to get super high, especially with the addition of electric motors, the math proves (video below) that a transmission isn't actually necessary.
This video is partially incorrect, as has been accurately discussed in the comments below. It is not correct to add resistance to the normal force on the rear tires to determine if the wheels can spin. A vehicle sitting stationary in strong headwind could still do a burnout (assuming the headwind doesn't create a bunch of downforce). The only thing that matters for spinning tires is whether or not you can exceed F = u*N (the maximum force the tires can apply, based on available traction). N, however, gets a bit complicated, and is dependent on at least four factors: 1. Weight distribution. 2. Load transfer due to acceleration. 3. Downforce on the car. 4. Load transfer due to wind resistance. Ignoring aerodynamics, the vehicle needs to exceed a rear wheel force of 2368.7 lbs (10.54 kN) to spin the tires, regardless of vehicle speed. Because the engine alone can create 90% of this force at 100% throttle at 5300 RPM (engine speed at 160 mph), adding in electric motors will be more than enough to spin the tires at 160 mph, even accounting for downforce (which, ironically and completely coincidentally, is very similar to the air resistance forces calculated in this video).
