Subaru R1e

The performance goals were for a daily driving range of 80 km (50 mi) and a charger capable of restoring the battery to 80% of full capacity within fifteen minutes.

[3] The delivered prototypes received intense interest from electric vehicle fans owing to their modern lithium-ion battery technology, appropriate size, and potential performance attributes.

The R1e was exhibited at Detroit in January 2006, billed as "the ideal ecology car" and touting its use of a lithium-ion battery pack, featuring rapid charging and low maintenance.

[10] Subaru would go on to release the electric concept G4e at the Tokyo Motor Show in late 2007 as a follow-up to the R1e with an improved battery, range, and bolder styling.

[3] Measured performance of the battery pack included a recharge capability to 80% capacity in eight minutes with a special rapid charger using 200 V, or to 100% charge in eight hours on a standard 100 V plug.
