Dear Sirs, Given all the coverage that the emergence of hybrid cars has received in your pages in recent months, your readers may be interested to learn that gasoline-electric hybrids are not a new phenomenon at all, but rather the latest incarnation of an idea that has been kicking around for over a century. Indeed, the hybrid car has been around almost as long as the automobile itself. At the turn of the twentieth century, as the automotive age dawned, three power-generating technologies competed for dominance: steam, gasoline, and electricity. In the year 1900, steam was well known as the power source of the industrial revolution, and electricity was widely regarded as the power source of the future, so it was not at all obvious that internal combustion engines burning a fractional distillate of crude petroleum would have any particular edge in this race for the powertrains ofAmericA、Indeed, when engineer H. Piper filed the first patent application for a gasoline-electric hybrid motor in 1905, his intention was to use the gas to give a little kick to his perfectly serviceable electric engine. His goal: an engine that could accelerate from 0 to 25 miles per hour in 10 seconds. Piper achieved his goal.Electric and hybrid-electric engines powered more than 35,000 vehicles sold in 1912. These cars were perfectly adequate for the time, but over the following decade they mostly disappeared from the market, through no fault of their own. The cause of their decline was the spectacular improvements in the cost and performance of gasoline-powered cars.An onslaught of fast and cheap internal combustion cars from Ford, General Motors, andBuick essentially buried the electric and electric-hybrid motors by the 1920s. Continuing performance improvements in internal combustion engines and inexpensive gas pretty much kept hybrids buried until the oil crises of 1973 and 1979 gaveAmericans a reason to start thinking about fuel efficiency.Engineers had the motivation to think about fuel-efficient hybrids, but they still lacked the means to make hybrids economically competitive with gas-powered cars, because the performance of gas-electric engines lagged far behind that of gas-powered engines in acceleration, top speed, and cruising range. Dramatic improvements in electronics and computer technology during the 1990s, however, finally made the hybrid a reality.Advances in battery performance and, most importantly, computer-guided electric power transfer created a car that could drive like a regular car, but do so on half the tank of gas.As another century dawns, perhaps we are entering into a new automotive age. The purpose of the article could best be summarized as which of the following A、To correct a mistaken impression about the performance of gasoline-electric hybrid cars B、To educate readers about the economic and technological potential of hybrid cars C、To refute a factually inaccurate statement made previously in the publication regarding the history of hybrid cars D、To acquaint readers with the history of gasoline-electric hybrid cars E、To educate readers about technological innovations at the dawn of the automotive age
