Milner to Introduce E-REV Prototype Alongside Flying Car Prototype at New York International Auto Show
|The prototype ElectriCar.|
Milner Motors is introducing an initial driving prototype of the Milner ElectriCar—an Extended-Range Electric Vehicle, E-REV) alongside the prototype Milner Motors AirCar at the New York International Auto Show.
The ElectriCar, based on the same basic design developed for the AirCar, is a four-door, lightweight vehicle designed to cruise 100 miles (161 km) on power from an 11 kWh battery pack at speeds up to 85 mph. For trips greater than 100 miles, the batteries will be charged en route by a small gasoline-powered generator, currently spec’d as a 125cc, 15hp unit. Two 48V DC motors will provide 40 hp peak, 15 hp continuous power.
Milner recently completed aerodynamic testing on the ElectriCar to determine the amount and coefficients of aerodynamic drag and rolling resistance. The rolling resistance is currently higher than desired (.022 versus .006—requiring 5 hp to overcome rolling resistance at 60 mph). Aerodynamic resistance was computed at .209 and with a cross sectional area of 1.5 m2, the CdA was computed as 0.313, or requiring 5 hp to overcome aerodynamic resistance at 60 mph.
The AirCar is a four-seat advanced-composite car designed to be able to fly to a destination, fold up its wings, and drive down the highway. The Aircar features a foldable main wing in the rear of the vehicle and a canard (smaller wing) in the front.
When airborne, the 28-ft wingspan, 3,000 lb. maximum weight AirCar will cruise at 200-mph for up to 1,000-miles. Power comes from two rotary engines that drive dual 28-inch pusher ducted fans. Once on the ground, the wings fold to 7-ft wide and a separate 40-hp engine powers the car up to 85 mph. The initial prototype is non-flying but drive-able.
The similarity of design objectives among both vehicles—and the re-use of numerous components—is at the core of Milner’s vision. Milner holds patents on both vehicles.
