just watched a few videos of fast muscle cars.
Dodge Demon, Hellcat, Shelby Mustang. and a tesla beat every single car in a race.
the Shelby did the best against any car vs the tesla plaid in the 1/4 mile but how or why is the tesla so much faster than every car?
this was a tesla plaid but watched some videos of tesla s and that thang was fast, too.

The races are rigged so as to give the electric car an artificial advantage. There are no rules against entering an electric vehicle into the Indy 500 or Formula 1 races. The reason you don’t see any of these cars entering is that internal combustion engines are far more efficient at speed than they are at a standstill.
Internal combustion engines develop power proportional to their RPM. To marry up an engine at high RPM with wheels at stationary, you need a gearbox and a clutch. The gearbox steps down the RPM, but only so far. The clutch is essentially two plates in oil, which can either be placed together or held slightly apart. When slightly apart, only some of the energy goes from one side to the other, but it counters for differences in velocity.
This clutch loses a lot of power to heat.
Then, just when the clutch is fully released, and the engine is putting down all its power… the engine now needs to spin too fast to keep accelerating, so you need to change down a gear, and now the engine is going slower, and producing less power.
Electric motors, however, produce 100% of their power at stationary, so off the line acceleration is very high. But the power drops off with increasing RPM, and its rare to put them through gearboxes with more than one gear ratio, so they get worse and worse as they get faster.
Teslas are awesome in a quarter mile, but pretty poor at a mile long drag race, and don’t have amazing top speeds. One trick pony
Electric motors are able to deliver 100% of their rated torque right away and EVs don’t have transmissions. Well, the Porsche does, but it doesn’t really need it. So, while gasoline and diesel engines have to rev up to their max power band and then shift into a higher gear and go through that process again, an EV *can just keep going at 100%*.
It is why sometimes, if the race goes long enough, the supercars will hunt down the electric car because at some point the gasoline car will hit their final drive ration (top gear) and the engine will rev up until it makes all the possible power. At that time it comes down to which car has more horsepower.

Electric motors deliver “all the torque, all the time”. Whereas gasoline engines only give peak performance within a certain range of RPMs, and the driver or an automatic transmission needs to intelligently change gears to keep the engine spinning within the RPM range that delivers peak performance. Also, it takes some time for the engine to reach the RPMs of peak performance every time you change gears.
So basically, an electric car accelerates better than a gasoline car partly because electric motors are so much faster than gasoline motors, but also because they cut out a certain middleman called the transmission.
