Originally for solar racing car.
Additional FeaturesWe are armature team of solar-car racing in Japan.

We made Prominence 4X-8, for Shikoku EV Rally.

It is street legal as moped car in Japan.
(It like NEV in US, and quad in EU.)

Moped EV car has power limit, it is only up to 600W.

So, we carried out thorough lightening and reduction of the air resistance.

As a result, Cruise at 60km/h was able to come out at only 600W.

Prominence 4X-8 class won (class of moped car,lead-acid batt.) 2006 Shikoku EV rally.

Shikoku EV rally is famous in Japan, as use general road competition. WebPage
