I took delivery of a Model 3 last week, so I still have one more day to return the vehicle. I want to determine if I got a lemon -- the range of the car has been about 10% less than expectations, based on the Teslike chart. Here's the bottom line: Driving 68mph in good conditions, I got 17.6% less range than the EPA rating, which is more than the 8% hit I was expecting based on the Teslike chart. My questions are: Is this normal? Is the Teslike chart accurate? Is there a breaking in period? Is it possible I got a dud? I'd really appreciate any help, since I have to make a decision soon. Here are my details: Model 3 Standard Range Plus 19" Tires Car condition: New, about 540 miles on it so far Trip length: 99.8 miles Average Speed: 68mph (I set the AP to 68 for the first 70 miles, then set it to 70 mph for the rest. There was also a 2 mile stretch of heavy traffic, which brings the average back down to 68.) Charge Used: 121 miles (started at 195, finished at 74) Wh/mi: 253 Weather: 60 - 65 degrees Elevation: Relatively flat for most of the trip AC/Heating: None I've taken a few other long trips with this car, but it's hard to determine the efficiency because the terrain was hilly, and my speed varied. That said, when I did calculations during those trips, my range was about 24% below EPA, and my average speed was around 70 to 75 mph (these were 70mph zones). Thanks again for your help with this.
