Taycan top speed

Morning Guys - Quick Q to the forum

Why does the Taycan top out at c. 145-160mph

Have just been looking at the staggering perfomance numbers 0-60, so slighly surprised by the top end being so much lower than a 911

Not that top speed is faintly useable in UK - just interested in the EV/ICE mechanics - is it the flat/non-existant torque curve?

Does the mean for EV's generally - when the 0-30, 0-40, 0-60 are staggeringly quick

are the 30-70, 50-70's etc not quite as headliine grabbing?

No gearbox in an EV, although I think Tay can has a 2 speed box unlike others. So no gears mean the motor has to work over a large range and lower speeds are more of a priority

The intermediate acceleration figures are still outstanding.

Higher maximum speeds have a number of issues including.

-Battery cooling would need to be improved. Drawing this much energy from a battery so quickly isn't straightforward, and will impact battery life.

-Brakes. At 185 mph the vehicle has 50% more kinetic energy than at 150mph, so now you need to increase braking capability significantly, on an already heavy vehicle with large brakes.

-Range. This might be so low at higher speeds as to be effectively unuseable.


With current tech it involves significant design choices which add cost and complexity. Most consumers won't want to pay the extra.

If you have an EV with an identical 30-70 time, the EV would still be quicker side to side. If the timer starts at the signal to go, then the EV drivetrain reacts much quicker and the car is gone. This is in contrast to when a timing device starts at the point the car accelerates, which will negate the lag time.
