So I recently had a chance to drive the Model 3 for a day (a February build). I drove approximately 200 miles in a combination of street and highway driving and got an average energy use of 227 wh/mile (implying a total range of 330 miles on the 18 inch wheels without the aero caps!). Here are my thoughts from that experience: Very efficient in combination driving - It was a crisp 65 degrees for most of the day and I drove about 200 miles all in, ranging from highway driving up to the mid 70s mph to street driving in the 25-40 mph range. I was riding on 18 inch wheels without the aero caps, with two adult passengers, and I still managed very high efficiency with an implied range of 330 miles or 227wh/mi! I wonder how much of a hit the 19s would have on this range. Screen works very well, even at night - I was initially concerned about glare from the large screen during the day but did not find that to be an issue despite it being a fairly sunny day. At night, I was also not distracted from the screen in Night mode with auto brightness turned on (it was at 22% brightness). I do wish that some of the controls were more well located (e.g. the volume control for the navigation) so I'm hoping that will be improved in future software. Sound system is very good - So I tried the sound system a couple of days earlier in the Tesla showroom and was blown away by the crisp midrange and "immersive" sound, particularly when the "Todays Hits" streaming channel was on (try listening to the song Somebody Special by Nina Nesbitt to see what I mean). It sounded better to my ear than the Tesla Model S in the showroom. When driving, the sound was less impressive (due perhaps to the ambient noise from wind/tires) but still very good. Autopilot worked better than expected - I had never driven using the Autopilot before but was impressed at how generally smooth the acceleration and lane changes were. This car was running the latest 2018.12 software. I still didn't get used to where the sensors are in the steering wheel, because even when I rested my hands on the bottom of the steering wheel, it would still alert me to grab the wheel (so I would end up squeezing the top portion of the steering wheel). I guess I have more to learn about the tricks with Autopilot in this regard. Regen works great - The regen on the car worked very well, particularly strong at lower speeds. In my Fisker, a lower regen setting appears to get greater overall mileage and efficiency in most applications but on the Model 3, trying out Standard and Low, it seems like Standard generates better efficiency. Does the brake pedal only activate the friction brakes? (I know in the Fisker the brake pedal uses a blended system activating both regen and friction depending on how far it is depressed). Wind noise wasn't distracting - The wind and tire noise were definitely noticeable in my drives but not out of the ordinary for most cars of this size. For some reason I was expecting it to be quieter but I'd say it was about average for a car in this size (perhaps a little more noticeable than a Lexus IS and about average with the C and 3 series). Ride quality was okay - definitely felt the bumps - Driving through city streets in the NYC area, the bumps were very noticeable (even while avoiding the big potholes). It was definitely not a soft ride but I didn't find it overly harsh. It's been a while since I've ridden in an MS with Air Suspension so hard for me to compare. I would say the car rides a little harder than my Karma (I think the added weight on the Karma helps dampen some of the harshness). Steering wheel doesn't tilt - I was surprised that although the steering wheel telescopes and raises up and down, it doesn't tilt. The steering wheel angle is always locked in place. Took a little getting used to. Back seats are not as comfortable - My biggest gripe with the M3 are the back seats. I'm not a particularly tall person but there is absolutely no thigh support in those seats and they sit very low to the ground. Compared to the S, I think they sit 1-2 inches lower - that doesn't sound like a lot but it makes a big difference in how much of your upper leg has support. I think the backseats will be acceptable for short rides, but I don't think most of my friends of average/tall height would enjoy taking a multi-hour roadtrip back there. Maybe someone will come out with an aftermarket seat cushion that is angled up to support your legs while leaving your behind touching the actual seat. I think people would feel less uncomfortable/fatigued if they had more leg support. Acceleration not as quick as I expected - Okay, so first let me say that the car is quick. I think DragTimes clocked it at 4.7s 0-60. That said, its definitely not Model S quick and my day ride with the car is making me rethink whether or not I want to wait for the AWD or P versions of the M3. Highway passing speeds were more than adequate, but I felt the 0-40 mph seemed slower than the MS. Headrests not adjustable - Small gripe here but nowhere near a dealbreaker. Unless I'm mistaken, the front headrests are not adjustable. Not sure why Tesla didn't add those in to the premium seats, especially since they're in the S and they're also in the middle back seat of the Model 3. Overall, the car was fantastic. I may hold off purchasing until I get the specs and timing on the AWD/P versions.
