I've been thinking about how the 3 is different than my Model S and I came up with this list vs my April 2014 Model S: Autopilot Didn’t exist in April 2014 for Tesla Active safety Automatic emergency braking, collision avoidance etc. These didn’t exist on the S in 2014. All-Wheel Drive Also didn’t exist in April 2014 LTE network connectivity Also not available in 2014. Faster maps, faster streaming Available as a $500 upgrade for my Model S, but not worth the price Built-in front console I added an aftermarket EVannex CCI to make up for this Rear cup holders I added an aftermarket EVannex Rear console to make up for this too although it’s not nearly as convenient as the flip down cup holders in the Model 3 Rear USB ports Coat hooks I added EVannex aftermarket coat hooks for my S Front door storage areas/pockets Rear set pockets Cargo cover In this case via a trunk, but in my Model S they didn’t provide the rear cargo cover and it was always too pricey after the fact Size The smaller size of the 3 can also be a benefit for those with smaller garages, and parking in the cities or in general. The Model S is a very long and wide car which can make it a real pain to park at times. Speed While new Model S’s all outperform the Model 3, the 0-60 is 5.4s in my Model S85. The long range Model 3 does 0-60 in 5.1s and will probably be a bit better when configured with AWD. The Model 3 will be faster than my S. Range The long range Model 3 has a smaller battery than my Model S (80kWh vs 85kWh), yet is rated at 310 miles of range vs my 265 mile rating. That 310 will also likely be a shade longer with AWD configured. Premium audio I have standard Audio in my S and wouldn’t pay for premium as an extra but it seems it would come with the package in the 3. Fog lamps Smart phone docking in center console Model 3 climate control system with the fancy new air direction controls Adjustable height seat belts This is a big deal for my wife as she’s 5’0″ and the S ones are too high for her Lighted vanity mirrors My S has vanity mirrors, but no lighting. Power close charge port door This doesn’t exist on early Model S’s Unkown items There are also a few items that I suspect will be better in the 3 than my S: Tire Pressure Monitoring System This one I’m a bit unsure of. A TPMS exists in the 3, but can you see individual tire pressures as you can on the newer S’s? If so that is something I don’t have. Today, I can only tell if a tire is low and then I have to check all 4 to find out which one is low. It would be great to be able to see the actual pressures in each tire rather than checking them all by hand weekly. Seating While I don’t have a problem with leather, supposedly the new material they’re using instead of leather is quite durable and comfortable. I have the first-generation Model S seats, they’re on the 3rd generation right now for the S. Those first generation seats are pretty uncomfortable on long drives. I expect the Model 3 seats to be better than the ones in my Model S. Heated steering wheel This doesn’t exist on my S even though I have the cold weather package as it was added into the package later. The newer Model S’s have this. I don’t know if it exists on the Model 3 or not. If it does it would be a welcome addition. Road noise The original Model S’s were poorly insulated from road noise. In newer cars, they tightened up the tolerances, added more sound deadening material and generally reduced the noise. I suspect the Model 3 will be quieter than my Model S. That's a lot of progress in 3.5 years!
