Wheel Fairings: Aerodynamically Designed
The Elio wheel fairings have been one of the most widely discussed topics among the Elio Motors reservation holders. So much so that this week’s Tech Talk is dedicated solely to this one aspect of the Elio.
For those who have been monitoring the evolution of the Elio exterior styling, you are aware that the fairings have been slightly modified with each Prototype. The latest production design direction is primarily based on how best to improve the aerodynamics.
The high mile per gallon requirement drove the design team to revise the fairings in order to provide the least resistant airflow while still having a design that was complimentary to the body styling. The fairings’ NACA shape is absolutely critical to reduce drag on the vehicle and maintain the highest mileage possible. The Elio engineers are still in the process of honing the final aerodynamic shape of the fairing, but the overall theme of the styling won’t change significantly. While a fairing of this nature is fairly unique compared to most vehicles on the road, the reality is our overall vehicle styling and layout is equally unexpected alongside vehicles on the road today. Therefore, this design execution is yet further confirmation that the styling is an appropriate fit.

Performance in Snow
So, how do the wheel fairings perform in snow? The soon-to-be-released Elio video will demonstrate how well it handles in more compromising weather conditions. Keeping in mind that the Elio in the video is a prototype, that fact alone further builds confidence that the Elio will provide the same reliable traction as in other front-wheel drive vehicles.
One of the reasons snow-pack is problematic on standard vehicles is that the buildup causes an interference with the turning and jolting of the wheels. Because the fairings turn with the wheels, and the suspension is independent of the fairing, neither of these are a concern. There is also an inner fender liner for both the front wheels and rear wheel that is designed to accommodate chains. The distance between the liner and the tire has been designed in such a way to minimize snow build up. Although the attachment scheme of the fairing is still a work in progress, the goal is to make it as easy to remove as possible for maintenance and tire access.
