eGX Racing Kart is a concept for now, but its greatest appeal is that it's powered by two 1.3-kWh batteries that last for up to 45 minutes of flat-out driving and can be replaced in under 30 seconds.
The batteries take around five hours to charge, but the simple swapping procedure means that the fun doesn't have to stop when the charge is depleted. The eGX kart uses Honda's Mobile Power Pack batteries, which are designed to be easily replaceable. Measuring 11.7 inches by 6.2 inches by 7.0 inches, the MPPs are roughly the size of a two-slice toaster and weigh 22.7 pounds. Thanks to sturdily integrated handles, transporting the battery is a breeze. The MPP is already in use in Japan, where electric-moped riders can stop at stations to quickly swap out a depleted battery for a fresh one rather than wait for their bike to charge.
We sampled the eGX Racing Kart during a recent event at Detroit's M1 Concourse. The kart itself is a pretty standard affair, using a Parolin chassis with minor changes for new mountings. The eGX measures 77.9 inches long, 53.1 inches wide, and 23.2 inches tall, sans driver of course, and weighs 230 pounds, slightly heavier than a gas-powered shifter kart. The wheelbase stretches 41.3 inches long.
