While Tesla prepares to release its economy-class Model 3, Shell has released its design for a more fuel-efficient concept car. It’s a gas guzzler, but it does some more efficiently. Try 89 miles per gallon.
The Project M was designed to be a city car. Shell reports it can achieve 89 miles per gallon at a sustained speed of 45 mph. It has a top speed of 70 mph, but Shell says it performs best between 30 to 45mph.
