It will be interesting to see the customizations and aftermarket stuff available for Elio. I'm not interested in aftermarket HP increases because they usually void the warrantee.
Edit: If the Elio has 55hp and 1,200lb that's a Power-to-Weight Ratio (PWR) of 0.0458hp/lb. A 1995 Honda Odyssey’s PWR is 0.0408 (140hp, 3435lbs) and it is reported to do 0-60 in 10.1 seconds. The Elio's slightly better should PWR should allow it to achieve 0-60 around 9.6s.
PWR is generally reported in lbs/hp, or 21.8lbs/hp for the Elio. (assuming 1200lbs, 55hp)
