From the website autocial.com:
About the engine: "And, while an electric drivetrain packages and is envisioned for the Edison2 (with a name like that…), the X-Prize contestant vehicle will be powered by a 1 cylinder turbocharged 250cc 40-hp Yamaha engine that operates without a throttle. Engine power delivery is regulated by altering the amount of exhaust-gas recirculation in the cylinder."
And the body: "The aerodynamic teardrop shape was honed by a Northrup Grumman expert, and boasts a Cd of around 0.15 (which would rise a bit if developed for production). Note the fixed wing-shaped outriggers supporting the wheels. These don’t move. A patented new suspension packages inside the wheel envelope, blocked from view (and the wind) by the enveloping cycle fenders (they’re mum on its design, but it must be like the Michelin Active Wheel."
The aero engineer was no other than Barnaby Wainfan (
