batteries. After years outside the limelight, the energy crises of the 1970s and 1980s brought about renewed interest in the perceived independence electric cars had from the fluctuations of the hydrocarbon energy market. However, vehicles such as the intensely-marketed Sinclair C5 failed. General Motors created a concept car using another gasoline car as the base, the Electrovette (1976). At the 1990 Los Angeles Auto Show, General Motors President Roger Smith unveiled the GM Impact electric concept car, along with the announcement that GM would build electric cars for sale to the public. From the 1960s to the 1990s, a number of companies made battery electric vehicles converted from existing manufactured models, often using gliders. None were sold in large numbers, with sales hampered by high cost and a limited range. Most of these vehicles were sold to government agencies and electric utility companies. The passage of the Electric and Hybrid Vehicle Research, Development and Demonstration Act of 1976 in the US provided government incentives for development of electric vehicles in the US. Electric Fuel Propulsion Corporation (now Apollo Energy Systems) produced the Electrosport (a converted AMC Hornet), the Mars I (a converted Renault Dauphine), and the Mars II (a converted Renault R-10). Jet Industries sold the Electra-Van 600 (a converted Subaru Sambar 600), the Electra-Van 750 (converted Mazda B2000/Ford Courier pickup trucks), the Electrica (converted Ford Escort/Mercury Lynx cars) and the Electrica 007 (converted Dodge Omni 024/Plymouth Horizon TC3 cars). U.S. Electricar Corp., based in Massachusetts, sold the Lectric Leopard, a converted Renault 5. Electric Vehicle Associates sold the Current Fare (a converted Ford Fairmont) and the Change of Pace (a converted AMC Pacer). U.S. Electricar, Inc., based in California, sold a converted Geo Prizm. Solectria Corporation (now Azure Dynamics) sold the Solectria Force (a converted Geo Metro) and the E10 (a converted Chevrolet S-10). Later, General Motors would also produce an electric S-10, the Chevrolet S-10 EV, based on the General Motors EV1. In the early 1990s, the California Air Resources Board (CARB), the government of California's "clean air agency", began a push for more fuel-efficient, lower-emissions vehicles, with the ultimate goal being a move to zero-emissions vehicles such as electric vehicles. In response, automakers developed electric models, including the Chrysler TEVan, Ford Ranger EV pickup truck, GM EV1 and S10 EV pickup, Honda EV Plus hatchback, Nissan lithium-battery Altra EV miniwagon and Toyota RAV4 EV. The automakers were
