Default Why Many of The Latest Luxury Electric Cars Fall Short on Range and Efficiency

Bigger batteries for electric cars mean more weight. But conventional automakers haven't developed batteries that are as light and cheap as Tesla's.





The latest electric cars come with giant batteries, often up to 100-kwh, or enough to run a hair dryer on hot for almost 3 straight days.

That can be a great thing for range, giving cars like the Tesla Model 3 and Model X more than 300 miles between charges. But the picture isnít all rosy.

Those same 100-kWh modern cars are so heavy that they compromise one of the main reasons for electric carsí existence, their efficiency.

Where the average new gas car got just 24.7 mpg in 2017, the average electric model gets 117 miles per gallon equivalent. That is, it uses the same amount of total btus of energy as a car that got 117 mpg.

Some of the latest luxury models with big batteries aiming for such long ranges, however, miss their targets at least in part because the sheer weight of their batteries makes them inefficient.
