Exactly, I never knew Model S was made that much better. Wonder why Tesla did not promote such advances? Truly remarkable vehicle.
Because it was really not that much better.
We had a 2015 Model S P90D for six years that we replaced with a 2021 Model S Plaid. Yes, almost everything about the Plaid was different from the earlier Model S. But better? Not so much, especially when compared to the Lucid Air Dream Performance we got about four months after we took delivery of the Plaid.
The later Model S marginally improved seating comfort without actually increasing cabin volume. The Air blew it out of the water on that score.
The interior materials of the Plaid were different from the earlier Model S, but they were not better.
The Plaid had air suspension which was not available on the earlier Model S, but it was no match to the Air and its coil-spring suspension. The Air stayed planted under hard acceleration, whereas the Plaid went light in the front end to the point that you quickly had to get off the throttle, thereby making access to its power limited.
Our Air is still rock solid and rattle-free at well over 40,000 miles. The Plaid was squeaking and groaning in its rear quarters by 10,000 miles.
The Plaid software was more stable than the Air's, at least until UX 2.0 came along, but it was not problem free. Besides occasional screen reboots being required, we went through repeated days-long bouts of the car not responding to the key fob to open doors and sometimes not to start the car, either.
The Plaid had active noise cancellation (or claimed to). The Air did not and was still the quieter cabin.
And here was the real kicker. The Plaid was delivered with significantly more defects in body, trim, and paint than the 2015 Model S . . . and with no fewer than our early-production Air. And this was before the yoke cover began peeing off.
Believe me, Tesla didn't really have all that much to brag about with the Model S changes.
