My 2nd attempt to buy the Model S 90D failed. I could not convince myself yet to buy a MS. I am holding Mercedes E 43 AMG as the benchmark car. Below is the comparison based on my experience. Model S falls short. I might need a push from you all if I am to buy an MS. Abbreviation for Merc E class. will be "ME". Advantages of MS: Torque: 0-60 for ME is 4.5 sec and MS is 4.2. The instant torque of an EV gives a MUCH better experience and there is no turbo lag. Autopilot: Tesla will have a better autopilot. ME has some safety features related to Autopilot like auto breaking and lane keeping, but not as good as MS. For convenience and active safety MS is better Apps: Tesla's mobile app is and other apps built using Tesla's API are much better than Merc. Interface: I like the screens and touch based interface of MS Exterior looks: MS looks good. I like the nose and real tail lights. 3 year cost to own: Maintenance cost and depreciation is less for MS. Disadvantages of MS: Charging: Note: I don't have home charging. Have to charge at work or in Superchargers. The frequency of charging is high because the rage of a fully charged MS is lesser than a fully fueled ME. Range of MS is just 58% of ME. Charging duration for MS to 80% is 800% slower than fueling ME even by using a super charger. Charging to 100% is 1500% slower than ME. Availability of charging stations are not as good as gas stations. Charging within a destination city is MUCH shower (Only NEMA / Chademo) than superchargers. Safety Rating: 2017 MS is rated lower than 2016 ME overall in the IIHS website. Interior Design: The interior design of ME is beautiful and elegant. MS is too bland for my taste. Also no door storage in MS. Cabin Noise & Ride Quality: Cabin noise in MS is higher than ME. I drove on the same road at the same speed with a sound meter app on my phone. MS was 6 dB louder. ME also had a smoother ride. Features: Features like ventilated seats not available in MS Build Quality: Panel gaps, interior finishing and materials choice, trim alignment etc are not very good in MS. Audio: Premium audio in MS not as punchy and detailed as ME Price: The price for both cars as configured is: MS - 106,800, ME - 89,155 Overall I think MS scores a bit less than ME. I am willing to wait several months for MS to catch up. Specifically in areas of charging speed, cabin noise and build quality. Hopefully the price comes down when 2170 battery cells are used for MS.
