When we talk about charging speed a lot of times we talk about percentages, how long it takes to charge from 0% to 80%, or from 10 to 75%. The problem with that is you’re not comparing the actual miles gained per minute.

If you compare the very efficient model Y to some of the other vehicles and see how much battery capacity each one of these need to travel 315 miles, you’ll see that the model Y only needs four-kilowatt hours of battery to go 315 miles.

Whereas, the least efficient vehicle on this list needs 147 kilowatt hours of battery to go that same 315 miles. Since a model Y can travel 315 miles on about half of the battery capacity of the E-Tron.

It becomes very clear that it’s going to take a lot longer to add a hundred miles of range to the E-Tron, than it would the model Y.

One of the first ways Tesla was able to achieve great efficiency is by keeping the model Y very light. If you compare the model Y curb weight to some of its other competitors, you’ll see that the model Y curb weight of 4,416 pounds is the lowest on this list.

The Jaguar iPace as we talked about in a previous post is roughly the same size vehicle, but it weighs almost 300 pounds more. The heaviest vehicle on this list is the Audi E-Tron coming in at a whopping 5,843 pounds.

Curb Weight Comparison
Rank Model Battery Curb Weight
1 Model Y LR AWD (19″) 74 kWh 4,416 lbs
2 Jaguar i-Pace 90 kWh 4,702 lbs
3 Mustang Mach-E 98.8 kWh 4,890 lbs
4 Model X LR+ AWD 100 kWh 5,631 lbs
5 Audi E-Tron 95 kWh 5,843 lbs
Model Y Drag Coefficient
When it comes to any vehicle but an electric vehicle weight matters a lot because it takes more energy to move a heavy vehicle. Another big factor when it comes to the efficiency of a vehicle is the drag coefficient.

The drag coefficient measures how much air and wind resistance the vehicle encounters when it’s driving, the model Y on this list has the lowest coefficient of drag at just 0.23.

The Model X is the second-best on this list with a coefficient of drag of 0.25, the Audi E-Tron at 0.28, the Jaguar is at 0.29 and the Mustang Mach-E they have said it will be below 0.3.
