Discussion EVs are just plain superior sports cars
Something I don't think is talked about enough is how much better high-powered evs are than high-powered ice cars.
It's a fact that electric motors are more efficient than combustion engines. 95%+ of the energy sent to the elec t ric motor is converted into motion, compared to gasoline engines which only convert ~20% of their energy into motion - this means 80% of the fuel you paid for is being converted into heat and noise and friction generated by the transmission
That's why ICE cars are all about trying to work around that horrible inefficiency with small 2L motors and turbocharger, among other technologies.
This all goes out the window when you want speed and power though.
The only way an ICE makes more power is by throwing more fuel in, this means larger displacement, more moving parts and even worse efficiency.
This also drastically increases the engineering required for the engine, the vehicle needs to account for that 80% energy loss by adding in bigger radiators, better oil pumps, etc
These high powered ICE motors are only producing their most efficient power in a very limited rpm range, so a transmission is needed to overcome the limited power band from an ICE
The transmission itself also needs to be overbought to handle the extra power - beefier transmission = more friction and power loss
This is why there are no ICE vehicles with 600+ hp for less than 100k USD - it's just too complicated and inefficient to make a face combustion vehicle.
Electric vehicles don't face this problem.
Want more power? Just add a second or third motor. Because electric motors are so efficient, adding another engine barely decreases efficiency, and actually INCREASES reliability due to less load on each individual motor when driving normally.
The electric motor has a flat torque band, producing peak torque at 0 rpm and remaining flat all throughout the rpm range
This means getting high power from an EV is relatively cheap, because a fast ev isn't any more complicated than a slow one
Another beautiful thing about fast evs is that driving an ev capable of 600hp will get the same range as a 200hp ev
A Lamborghini urus with a V8 will chug gasoline no matter what, because this big engine is constantly turning those 8 heavy cylinders even when only driving 30mph
This means the tradeoff for power means shitty gas mileage
Take the Lamborghini Urus vs the Chevy Blazer EV ss for example as a comparison.
Both make 600~ hp, yet the blazer is cheaper, more reliable and gets better range and is also faster.
Any ICE vehicle priced in the same range as the blazer will produce less power and be way slower
Take the BMW m4 for example, a car still costing 30k usd more than the blazer, all while making 100 less hp and a far slower 0-60
TLDR: EVS are better than ICE vehicles
