Best Mild-Hybrid Cars of 2024

Mild hybrid cars are becoming commonplace as automakers reap the benefits of low-key electric assistance in their vehicles. Not to be confused with a full hybrid vehicle, mild hybrids use a standard internal combustion engine paired with a small battery that adds electric power to reduce fuel consumption, improve performance, and make for smoother driving. The most common setup is a 48-volt system that alleviates how much work the engine has to do by powering accessories like climate control and providing an extra boost, where needed. In some cases, an integrated starter generator can be added, too, for a slicker auto stop/start experience. These systems are now found in many modern vehicles.

Here is a list of the best mild-hybrid cars available in the USA for 2024:
