As we've said before, the concept car is using Volkswagen's modular electrification kit, known as the MEB. That was first seen on Volkswagen's BUDD-e microbus concept, pictured below, at the Consumer Electronics Show in January.
Volkswagen has said that the MEB will give its electric cars mileage "on par with today's gasoline-powered cars by the end of the decade." If the 248-mile to 372-mile range Volkswagen is touting for the I.D. is true, Volkswagen isn't off with that claim.
Competition is mounting in the electric car space. Tesla recently announced a battery upgrade that will increase the range of the Model S with Ludicrous mode to 315 miles, and the Model X with Ludicrous mode to 289 miles. The Chevy Bolt will have a range of 238 miles when it hits dealerships by the end of 2016.
The Volkswagen concept isn't a reality yet, so we will have to wait and see if the production vehicle has a competitive verified range.
Still, Volkswagen's concept car shows it's serious about competing in the EV space, and increasing range is a critical component of doing so.
