Comparison of 2021 Tesla Model 3 LR and 2017 Chevy Bolt LT

The Tesla Model 3, first released in 2017, was the first EV to exceed 1 million annual units sold. The Model 3 was originally marketed as a more-affordable EV with mass market appeal, but is generall considered a midsize luxury sedan. It earned Popular Mechanics Car of the Year award in 2018.
The Chevrolet Bolt was first introduced for model year 2017 and became the second best selling EV in the US. It has been the tarnished with concerns over battery fires which has led GM to recall and replace all affected drive batteries, a massive undertaking. The replacement batteries and batteries for model year 2020 where increased in size. In 2022, Chevy introduced the Bolt EUV with a slightly longer wheelbase.
  2021 Tesla Model 3 LR 2017 Chevy Bolt LT 2020 Toyota Camry LE⁵
Approximate Price¹ $48,000 $40,000 $25,000
Useable Battery Size² 70 kWh 60 kWh Gastank ~= 479 kWh
Efficiency³ 4.27 miles/kwh 3.4 miles/kwh Gas ~= 1.1 miles/kwh
Range at 70mph⁴ 298 miles 204 miles 526 miles
¹Prices of electric vehicles are highly volatile and greatly depend on options and dealer charges included. The price show is an estimated price of the comparison vehicle including in the "ChargeDischarge.com" test.
²Manufacturer's often hold back some of the battery capacity to extend the battery life and/or are not forthcoming about the usable battery size.
³Efficiency greatly varies base on many factors. The value here is from testing at 70MPH. See references below.
⁴Similar to efficiency, the range value shown here is just the battery size times the efficiency. This gives an estimated MAX range for a full battery and driving at 70MPH.
⁵The Camry gas tank size of 15.8 gallons and efficiency of 38 miles/gallon has been converted to the battery equivalents.

Comparison Graphs

Each bar in this graph represents the Range Added with 20 Minutes of Charging for different STARTING states of charge (SOC). This 20-minute charge mile rating is a common comparison metric for electric vehicles. It is a measurement of much range can you add with 20 minutes of charging. Even this will be greatly impacted by a variety of factors. A battery pack will charge faster when it is less 'full'.
The charge curve graphs here show for the Tesla Model 3 and the Chevy Bolt are a key part of the ChargeDischarge storyline for these two cars. The faster (more power) you can charge the faster you can add range. But do not forget that because the Model 3 is more efficient at an estimated 4.27 miles/kWh even at the same charge rate it will be able to add range faster (see: Miles of Range per Charging Minute).
Each bar in this graph represents the Number of Charging Minutes required to add 100 miles of Range for different STARTING states of charge (SOC). It is another common comparison metric. This graph shows the values for both the Tesla Model 3 and the Chevy Bolt. Note that because the charging rate (power) will be reduced as the battery 'fills', the 100 miles of charging is faster when the battery is nearer to empty.
Although this "Miles of Range per Charging Minute" graph is not seen as often as the charging curve above, it really is a better comparison tool as it includes the efficiency of each vehicle. In this case, the Model 3 will have its values 'improved' by its better efficiency.
