Why do EV's in general have poor top speed
Compared to my Mustangs in the past, it seems EV's in general have poor top speed EXCEPT Tesla, why ?
Tesla Model 3 RWD base. 139 mph
Tesla Model S 162 mph
Mach-E Select/Premium 112 mph
Mach- E GT 124 mph
Chevrolet Bolt EV 2LT 90 mph
Nissan Leaf Plus 98 mph
Mini Cooper SE 93 mph
Kona Electric 103 mph
Ioniq 5 115 mph
2007 Mustang GT 149 mph
2021 Mustang GT 159 mph
Single speed transmission is the easy answer. Even electric motors have a max safe RPM.
It seems some Tesla's have dual motors with each motor having a different ratio to enhance low and high speed performance. The Plaid motor can spin over 23k RPM, which explains it's 200 mph top speed.
The Mach E also has different ratios front and rear.
Actual Plaid top speed is in the 160s, at which speed it is reported to be terrifying. Tesla says it may be improved to 200 one day, but per Car and Driver it drove so poorly at 160 that 200 would be like a death wish.
It does though. Just like in ICE cars, different electric motors have different power curves and max RPM.
Design. They designed it for that speed. Others did not. And along with top motor RPM it is also about battery thermal management. The more heat the design can pull away from the battery then the higher its output levels can be for longer.
So basically, you don't want your EV motor to fly apart or your battery to burst into flames, and different manufacturers use different designs.
