I recently did an overnight test drive of a 2020 MX Performance (red) with G battery pack and 2020 MY Performance Stealth. Here are my main takeaways of the 2020 MX Perf as it compares to my 3 year old 2017 MX P100DL (grey) -
- Raven Suspension - The ride was noticeably and sometimes significantly more comfortable than my Pre-Raven air suspension. My 2017 has aftermarket 22" wheels and the test drive car had stock 22" wheels.
- Performance - I did back to back Launch Controls in Very Low Susp and Ludi++. The 2020 MX Performance is much faster than my 2017 MX P100DL (with 30k miles). Also, the extra torque in the front motor was noticeable in normal driving.
- Quality - Exterior cosmetic quality was better in the 2020 vs my 2017 MX. You can see in the picture the gaps above headlights are much tighter in the 2020 (red). Although the 2020 was not without issue. There was a creaking noise from the front suspension and the front passenger door jam had a rubber piece falling out. There was also an annoying front motor whine at certain speeds in the 2020.
- Audio - The sound system has been updated from the premium sound system from 2017. IMO the 2020 system sounded better. Another big change was voice call quality (was much louder and clearer). I also noticed that the car manages bluetooth audio volume differently/better. I believe this is a MCU1vs. MCU2 thing.
- FWDs - I didn't time this, but it seems the 2020 FWDs opened faster. Also, the metal frame is updated to reduce the contact point rubbing issue on older FWDs.
- Efficiency - This was okay, but not as significant as I was expecting.
- Efficiency - Wow. I drove the car in cold weather (30 F) and I was under 300 wh/mi overall (even with hard launches). Granted, I was driving a Perf Stealth Y with 19" Gemini (without caps), so that played a factor, but it was still surprising and significant relative to the old and new Model X cars. I took the same route under similar conditions and the Model Y was 120 wh/mi lower than the 2020 MX Perf.
- Quality - Was slightly worse on my test car than the 2020 Model X tester, but it could have been a fluke. The main issue was a window seal near the passenger mirror was bent outwards which caused a very loud wind noise. When pushed back into place, wind noise was not bad (but not great). I also noticed one of the speaker grills was falling off.
- Performance - Noticeably slower than the 2020 MX Perf and slower than my 2017 MX. Although top end power seemed to be better than my 2017 MX.
- Comfort - Seats were comfortable (about the same as 2020 MX). The car was on 19" wheels so not a great comparison, but it was not as smooth as the Raven suspension. However, during a 50 mile drive I did not feel uncomfortable. The full glass roof makes the car feel more airy/larger than it is.
- Wind Noise - Per above there was a piece of trim which made the wind noise very loud. When I pushed this trim back into place, window noise was better but still slightly louder than both MX cars. However, my test car did not have laminated glass.
- Rear Camera Quality - Relative to my 2017 Model X, the rear camera quality on the Y is not as good and often time lags.
- Interior/Cargo - We had one forward facing car seat and one rear facing car seat. Plenty of leg room in the front. Like the back seat pocks. Decent amount of cargo space. Missing the floor space on my 6-seat, but we didn't utilize it very often. MY felt narrower in the front but not uncomfortable.
- Controls - I liked the feel of the smaller steering wheel in the Y. Also the switch gear feels better, but I like having a separate Autopilot stalk with the MX. Hopefully Model Y gets the matte interior soon instead of gloss.
- Headlights - Noticeably better than both new and old Model X cars.
Based on above, I think the better buy for us is the Model Y over the Model X (we don't need a third row or the extra 10 cu ft of cargo). We will wait until January or February to see if MY gets heated steering wheel and other M3 updates before purchasing. If/when the Model X is updated, we may come back.
