AI Thread Summary
Electric cars provide instant torque at 0 RPM, a feature not easily replicated by internal combustion engines (ICE) due to their reliance on gearing and the risk of stalling at low RPMs. While theoretically, one can rev an ICE to its max torque using a clutch, this method leads to clutch wear and potential engine damage. Automatic transmissions can avoid stalling but may incur costly repairs if misused. The discussion highlights that ICE vehicles can achieve smooth acceleration through advanced transmission designs, such as CVTs, which differ from electric motors. Ultimately, the advantages of electric vehicles in terms of torque delivery remain significant compared to traditional gas and diesel engines.

the tesla falls on its face after 80mph after a gallant effort up to 80mph to have on par acceleration to any like 420hp car (actually, more like 475hp as folks are measuring 420hp at the driven wheels) after that speed, the car is anemic vs any car 300hp and even less!
I suspect that's an intentional design tradeoff, as Tesla could have remedied that by one more gear but at a cost of some loss in drive train efficiency, more mass, more maintenance, etc. For cars not targeted for the like of the German Autobahn, what's the point of 150 mph+ top ends that will likely enable spectacular crashes reported in the newspapers?

its cost savings and maintenance. more weight for a transmission , etc.
But, what's the point? why does any car go over 80mph. trust me, if Porsches had a limit of 100mph, no one would buy them.
the point again, is, the car is anemic past 80mph without a 2nd gear... its a trade off for the dependability. maybe folks are realizing that they don't need to go over 80mph.

Here is the revised dyno sheet with a similar hp gas engine with ratios like you have on the car.
