My thought is One Elio......One Model. We can already upscale our Elios with the many upgrade options to personalize.........perhaps two future drive trains.......Elio I.C.E. & Elio Electric.
The Elio will sell like hotcakes in it's current form. Future model year tweaks to update the body style, increase mpg, finally get the gas filler cap on the proper side, keep the low price in check, and improve safety features from model year to model year........simple and cost effective manufacturing.
I think Elio Motors will stand by it's business model and philosophy to build affordable, high mpg, and a safe commuter vehicle for the average driver.......o.k. possibly a roadster/convertible for those that feel the need to drive topless. The future Elio vision would more likely be a hovercraft.................not a four wheel vehicle.
