Tesla did shake up the sports car makers with the Performance versions of the S/X. Porsche of course is part of Volkswagen Group which is adopting electric cars in all their brands, but Porsche specifically has had their rep tarnished by a three row family SUV that can beat many of its cars in a drag race. It takes really over engineering an ICE for performance sacrificing almost everything else to beat what Tesla has done with a couple of family cars.
The top of the line Dodge (they have several muscle cars now, I can't keep them straight) is the best production drag car available, but that will be beaten soon by a 600 mile range sports car from Tesla that is probably a more practical everyday car than the Dodge drag only focused car.
Of course ICE are still better for prolonged fast driving (race track speeds), but the Autobahn is about the only place in the world where a regular driver might open their car up to 150 mph for an extended period of time. Instead most sports car drivers will only experience the performance their cars can deliver in short bursts and the advantages of an electric are much more obvious there. Going with an electric sports car about the only thing the average sports car driver is going to miss is the exhaust note.
The sports car companies see their future depends on electrifying their lineup and making something better than Tesla or at least on par. Companies like Porsche do have the advantage of designing sports cars longer than Tesla and Porsche's quality control is among the best in the world.
Tesla might lose out on the top tier sports car market, but while that was an early focus, it was ultimately a sideshow in Tesla's road map to the future. I'm sure Tesla would like to eat both VW's and Porsche's lunch in the EV world, but if they could only beat them in one arena, I'm sure they would prefer to be the EV world's VW rather than the top EV sports car maker. That furthers the goal of sustainable transportation much better than concentrating on the top end.
Sports car makers do not really understand the market fully. People spending in the low 6 figures want a car that is extremely quick, and will corner and brake reasonably well, but they aren't going to track the car or drive 200mph. Prior to Tesla marketing, folks talked more about 1/4 ETs and 'Ring times than 0-60 mph times, which was a stroke of genius by Tesla. Sports cars that were not AWD had been traction impaired for 20 years, by focusing on the 0-60 mph times, the Tesla was superior for the average performance car buyer than cars costing several times as much.
Why don't many folk track their $$$ sportscars? Because to do it safely, it requires you to cage the car and make other modifications that make it useless for the street. They are trailer queens once you put in the required safety equipment. If the Tesla Roadster runs 9's or is tracked by a sane person, they will have to destroy the interior of the car to use it on closed courses.
But if you are into performance cars for sport, Tesla is going to have a tough time of it. The automakers are in 'rick-measuring' contest, and it continues unabated.
You think a Dodge Demon is quick? This is a 2013 production Chevrolet as sold:
FF to 0:50
It's sold for drag racing. It is not the fastest version. It's the naturally aspired '456hp' model.
IIRC, they started selling them in 2012? You need a full cage, fire system, and parachute to run. We have hit the wall again, and this time I don't think they will move it. We were kicked off the dragstrip for running a stock production car 11.95 in 2002. We had to put a rollbar in it before returning. They moved that first to 11.50, then to 10.000. Do you really want to be in a car at 140 mph and roll it when the car in the next lane breaks and runs into you? Even with a cage, parachute, firesuit, and fire system, it's going to be memorable (knock on wood).
So we've hit a safety barrier with cars. Nobody would have believed it in 2000.
But most people aren't going to use their cars that way. They want the car but they do not want to drive it at it's true limits.
