Back in the 1950s, Bosch gasoline direct injection played an important role in one of the most famous sports cars of all time. In 1954, the technology was incorporated in the Mercedes-Benz 300 SL, a production car that would later be voted the “sports car of the century” by a panel of automotive journalists. Even at that time, gasoline direct injection was already managing to improve engine performance and fuel efficiency. In the Mercedes-Benz 300 SL, the system was primarily designed to offer agility and power. 60 years later, however, gasoline direct injection no longer stands for just performance, but also for efficiency and low emissions. This was made possible by highly precise manufacturing, sophisticated sensor technology, and advanced electronics which Bosch further refined over decades. Today, gasoline direct injection is economically viable and available for the mass market as a result.

Over 60 years ago, that could not be taken for granted. In its review of the 300 SL, the U.S. magazine Road & Track praised its “performance levels which are up there with – and even an improvement on – the best cars the automotive industry has to offer.”

Gasoline direct injection today: powerful and making strong headway
Today, gasoline direct injection is even available in small cars. More and more automakers are turning to the technology, which has become a key feature of strategies to meet future emissions guidelines. Modern injectors make a major contribution to cutting CO2 emissions and fuel consumption by up to 15 percent. In combination with downsizing or turbocharging, gasoline direct injection offers improved throttle response and enhanced driving dynamics. This is due to a torque increase of up to 50 percent at low engine speeds. Thanks to improved cooling of the combustion chamber, gasoline direct injection enables higher compression by further enhancing engine knock resistance.

Bosch showed it was in for the long haul by continuing to develop its gasoline direct injection technology over a period of decades. A broader market finally emerged when stricter emissions standards were introduced in the early 2000s, and since then sales have gone from strength to strength. In 2011, Bosch celebrated two production milestones when its global manufacturing network reached a total of 25 million fuel injectors and 5 million high-pressure pumps. Just one year later, in 2012, it doubled this achievement to reach 50 million injection valves and 10 million high-pressure pumps. By the end of 2013, these figures had skyrocketed to 80 million and 20 million respectively.
