Telsa's small drive units have a rated RPM limit of 18,000 RPM. With a 9.73:1 gear ratio and stock tires that are 751 rev/mile, the motor hits 18,000 RPM at 147.8 MPH.
155 MPH overrevs the motor by about 5% from it's rated speed.
Top speed is difficult to achieve with electric motors without the transmission. In addition to physical limits on rotor RPM and centripetal force, high RPM increases the necessary applied frequency from the inverter, and the inductive reactance of the motor goes up with the frequency. To put more current through the motor under high inductive reactance conditions needs more voltage, but you're limited by what the battery can put out. Especially at that condition when the voltage is already sagging from the current draw. Internal motor losses like hysteresis loss go up with frequency also, so you run into a loss of efficiency and a cooling issue at high RPM.
The disadvantage with that Corvette is that the motor's torque has to be limited to what the transmission can handle. The 0-60 times are not likely to be that impressive. They also lose efficiency with the transmission, both in internal friction and a huge hit in amount of regen it can utilize. Without optimally downshifting in a controlled pattern, you lose a ton of energy in the friction brakes.
As well, they saved a lot of weight using only a 44 kWh battery at the expense of range of course.
It's a purpose-built car for getting a top speed run, but completely impractical as an actual useful street vehicle.
