It is way too early to make judgements or comparisons of the driving and handling characteristics of Model 3 IMO. Let alone of track performance or endurance.
But surely it being smaller means a step in the right direction.
It is not too early for the car reviewers to start making comparisons. For example, in the review quoted in my post above, the Motor Trend reviewer referred to the handling of the Alfa Romeo Giulia as "a wet sponge by comparison."
Now, as it happens, Motor Trend also recently compared the handling of the Giulia to the Audi A4, BMW 3-series, Mercedes C class and a slew of other small ICE sports sedans/luxury cars.
It rated the Giulia's handling the best of the bunch:
On the other end of the spectrum is the Alfa. It was the nearly unanimous driver’s favorite, simultaneously a marvelous car to drive fast and still a comfortable commuter. The steering is quick, responsive, and talkative. The chassis responds perfectly to every input while muting every bump. More than any car here, it put the sport in sport sedan without suffering a jarring ride as a trade-off. A close second to the Alfa is the
Cadillac, which got the vote from the lone dissenter. But its equally phenomenal chassis and steering were offset by a less luxurious ride quality.
Alfa Romeo Giulia vs. BMW 330i vs. Audi A4 vs. Mercedes-Benz C300 vs. Cadillac ATS vs. Jaguar XE vs. Lexus IS 200t vs. Volvo S60
It also rated the Giulia its top choice of the comparable ICE sports sedans overall.
So Motor Trend's initial review compares the Model 3 favorably to the very best handling ICE car in its class. While more extensive reviews will be done I think it is quite clear already that the Model 3's handling will compare very favorably with the best BMW, Audi, Mercedes, Porsche can offer in the same class.
Also, I think you are looking at the performance benefits of Tesla's EV drivetrain too narrowly. Not only does a Model S have superior acceleration at 0-30 as you mention, but the P100D is far faster than the best performance sedans from Audi, BMW, Mercedes, etc. at 0-60, 0-100 and a quarter mile. Its passing acceleration is also much faster.
The responsiveness of an EV drivetrain also makes it much more enjoyable to drive IMO. I have taken my Model S on most of Hwy 1 in California, which is very windy in parts. The S's ability to quickly and effortlessly slow down and speed up when entering curves -- together with sure-footed steering -- makes it a pleasure to drive. I have also driven a Boxster -- known for its handling -- on the same stretches and I preferred the overall drive with the Model S. The ease and responsiveness of the drivetrain in and out of curves trumps the added nimbleness of the smaller car for me.
Frankly, the responsiveness of the EV drivetrain in my Model S has ruined me for ICE.
I think that is why I am struggling with your posts. You keep waxing poetic about ICE sports cars. But to me "ICE sports car" is quickly becoming an anachronism because the drivetrain -- the heart of the car -- just can't compete with a Tesla EV drivetrain.
