An another key technology relevant to fuel efficiency and emissions is fuel injection. In 1954, Mercedes Benz 300 SL proved fuel injection was better; having taken the technology from the airplane technology. "A fuel injector, by comparison is more elegant and more efficient, spraying the fuel more precisely direction into each cylinder." "After the energy shocks of the 1970s, Detroit began working on fuel injection." "Even into the 1990s, Detroit was still diverting precious engine R&D into power, not fuel economy." The EPA reported that 0 to 60 acceleration, since 1986, is up 19 percent, average weight up 20 percent. Fuel economy, meanwhile, fell by 7 percent." Quality costs, in 1992, GM spent $3 billion on warranty repairs, or about $829 a vehicle in the US."[Learn More ...]
