Get a Load of the World’s Most Efficient Electric Vehicle

Sweden’s annual Delsbo Electric Competition, which brings students together to build and test upgraded versions of energy-efficient, battery-powered rail cars, recently crowned a new champion.

The Eximus IV has been named the world’s most efficient battery-powered rail car at an annual electric rail car competition in Sweden.

Team Eximus—comprised of students from two Swedish universities—has broken the world record for the most efficient battery-operated car since it first entered the competition in 2016.

The Eximus IV, which looks like it came from outer space, is the brainchild of students from Dalarna and Chalmers Technical universities, and is able to reach 687 MPGe—the equivalent mileage you’d get with a standard gas-powered vehicle.

Contestants had to create a vehicle that moved six people, each weighing around 110 pounds, just over two miles down metal tracks instead of roads in order to minimize resistance.

Team Eximus was able to beat out the competition by utilizing aircraft materials to create a lightweight ride designed to move. The students also conducted wind-tunnel tests to check for ways to improve the vehicle’s performance and aerodynamics.

This year, some of the cars used canvas as a cover while others used what looked like glass for the top of the vehicle and metal for the body. It’s unclear what material Team Eximus used for its car this time around.

Eximus is used to victory. In fact, since the team began entering Delsbo in 2016, it’s created increasingly efficient versions of its own vehicles and set world records each consecutive year.
