2020 Tesla Model 3 SR+ Is The Most Efficient EV Ever (Beats IONIQ)
Tesla raised the bar for EV efficiency (EPA) to 239 Wh/mi (149 Wh/km) including charging losses.
The 2020 Tesla Model 3 is the most efficient electric car ever, according to officially released EPA ratings. The Model 3 now beats the previous leader Hyundai IONIQ Electric (2017-2019) and its upcoming 2020 model year version, which actually has slightly higher energy consumption.
In this post, we will focus on the Tesla Model 3 Standard Plus version, while a follow-up post will concern all 2020 versions.
First of all, the SR+ is rated for 250 miles (402 km) of range and efficiency of 239 Wh/mi (149 Wh/km), which includes charging losses. That's the best result ever in EPA stats (3.6% better than 2019 IONIQ and 5.5% better than 2020 IONIQ).
The SR+ is also state-of-the art in the case of highway efficiency - 255 Wh/mi(158 Wh/km).
The efficiency in the city is second only to the outgoing 2017-2019 Hyundai IONIQ Electric (by 1.3%): 228 Wh/mi (142 Wh/km) vs 225 Wh/mile (140 Wh/km), but Tesla offers basically more of everything else as a car (range, performance, tech).

What do you think?
* efficiency includes charging losses
As you can see below, the numbers for the Standard Range version were not updated, but we assume that efficiency is the same as in the case of the Standard Range Plus.
