Many people think that HEVs and electric vehicles are a recent phenomenon. But the history of HEVs goes back a long way. According to Rahman (2008), HEV production dates back to the early 1900s, when Ferdinand Porsche of Lohner Coach Factory developed the Mixte, which was a 4-wheel drive series hybrid version of the "Lohner-Porsche System". In order to extend the operating range, the vehicle included two generators driven by 2.5 hp Daimler IC motors allowing it to travel nearly 65 km on battery power alone. It had a top speed of 50 km/h and a power of 5.22 kW for 20 minutes. Since then, many other innovators have repeatedly attempted to bring a hybrid vehicle mass product to market, although there have been no studies demonstrating the demand. for products. A more recent working prototype of the hybrid electric vehicle was built by Victor Wouk, who worked on hybrid vehicles for decades in the 1960s and 1970s. His innovative work earned him the title "Godfather of Hybrid" ( Woku & Goodstein, 2004). His major work considered innovative was the installation of a prototype hybrid drivetrain of a 16 kilowatt (21 hp) electric motor in a 1972 Buick Skylark and was part of the federal Clean Car Incentive Program. U.S. Environmental Protection Agency which continued until 1976. The United States government's involvement in the quest for the development and use of fuel-efficient vehicles is an important part of the history and the development of HEVs in the United States. Several programs and initiatives have been launched at different times. An important program that played a role in the history of HEVs in the United States was initiated in the early 1990s. In a Congressional Research Service (CRS) report presented to Congress, Sissine (1996) presented that the 29 September... middle of document... The American market and American companies have also been globalized. Major Japanese automakers Honda and Toyota entered the U.S. market in the early 1980s. Since then, they have seen market share growth while the "big three" faced declining share. . Bradley et al. (2005) argue that differences between competitors in terms of cultures and associated philosophies have intensified rivalry within the industry. This rivalry is further intensified by the high fixed costs associated with manufacturing and low switching costs for consumers purchasing a different brand or model (Bradley et al., 2005, p.3). Rivalry and competition within the industry in the United States is coming into focus. In the United States, the industry is no longer dominated by the Big 3. In the field of heavy utility vehicles, Toyota has the upper hand, followed by other international and local manufacturers..
