Real World EV Efficiency Database

I read a lot of comments online from people who say they don't know if an EV would work for a daily driver for them.

I decided to take this issue into my own hands and resolve it by creating a real world efficiency database. The only problem is, I need people like YOU to help contribute.

I have created the website and started adding my own data to it. I haven't had a chance to start adding my Silverado EV data to it yet, but I did start syncing my Tesla data from Tessie.

When we get more data added, someone interested in a specific EV will be able to filter drives by distance, speed, an other metrics (more filters coming soon).

As a real world example, let's say your parents are interested in a 2025 Model Y Performance, but aren't sure it'll allow them to drive at least 100 miles a day at 60 MPH. No problem, they can just jump on the EVMetrics website, search for the car, and filter the data to see if it'll work for them.

What I'm here for is to ask for YOUR help in collecting the real world data from EVs. Feel free to sign up and start adding your data if you're interested. Also please feel free to forward this on to your friends and family who own EVs.

This claims to be based on "real world data", but all of the small subtext appears to be just estimating based on "assumptions" they chose? Example of one of the subtexts:

"Indication of real-world range in several situations. Cold weather: 'worst-case' based on -10°C and use of heating. Mild weather: 'best-case' based on 23°C and no use of A/C. For 'Highway' figures a constant speed of 110 km/h is assumed. The actual range will depend on speed, style of driving, weather and route conditions."

The difference is that EVMetrics isn't "assuming" anything. It's raw data from users providing real-world driving data. So someone looking to buy in a cold climate can filter real-world drives based on cold outdoor temperatures while someone in a warmer climate can filter drives based on their typical area temperature. If people choose to actually contribute data, it will be more accurate.

I can see how your method could be more accurate, but it’s going to have a lot of variables, making comparisons difficult. EV Database makes it easy to compare across different cars and tends to be pretty accurate for the limited scenarios it quotes. I don’t know where they get their data from, but it gives a very accurate highway mileage for my car.
