the two vehicles also offer air conditioning and heat as an option. Models ZX40ST Electric Truck The most powerful "fleet" electric utility truck on the market debuted at FedFleet '07 in Orlando in the summer of 2007. It is a version of the Hafei Minyi Pick-up. The truck is governed to a maximum speed of an hour and was claimed to travel 50–60 miles per charge. Like the ZX40S Advanced Design, this truck also uses an advanced three phase, brushless, AC induction motor, which comes standard with regenerative braking and optional air conditioning. MSRP $19,900. Sealed electrical connections, splash guards and weatherproof motors were options to add on. Daily users and independent tests found the actual vehicle range to be 21 to 24 miles per charge. ZX40 The Miles Electric Vehicles ZX40 is a subcompact electric car built by FAW Tianjin (Tianjin-Qingyuan Electric Vehicle Co), a subsidiary of the First Automobile Works in Tianjin, China. The car is a licensed version of the Japanese Daihatsu Move minicompact and is sold in China as the Huali Happy Messenger. Miles took vehicles without drivetrains and added the motor and electrical components. It is powered by a single 48-volt electric motor, which produces and uses a 150-amp-hour battery pack. The car uses an on-board charger that charges through a standard 120-volt outlet. An empty battery fully charges in twelve hours, but only four to six hours are needed to charge it fully if the car is less than 80% empty. The ZX40 was claimed to travel up to at speeds limited to . It is a 2- or 4-seat car and is DOT-approved for street use. The ZX40 was discontinued for the 2008 model year, in favor of the more powerful ZX40S and AC Motor-powered ZX40S Advanced Design. ZX40S The ZX40S is designed to accelerate faster than the ZX40. It is powered by a 72-volt system instead of a 48-volt system, which extends its claimed range to 50–60 miles (80–96 km). To comply with federal law, the ZX40S is also electronically speed-limited to like the ZX40 (except in certain states where electric vehicles which meet federal safety standards are allowed to operate up to 35 mph (56 km/h) as Medium Speed Electric Vehicles). The ZX40 and ZX40S are classified as "low-speed vehicles", meaning they have fewer regulations to comply with. Such vehicles must include standard lighting and seatbelts, but do not require passive
