During the 80s, manufacturers around the world became increasingly concerned regarding the effects of CO2 emissions and overall car pollution. In 1981, Mercedes-Benz became one of the first manufacturers to comply with the new environmental regulations and introduced the closed-loop three-way catalytic convertor to reduce overall car pollution.
Additionally, Mercedes-Benz introduced several other changes in their vehicles, such as oil filters and air filters, thus allowing the company to gain more success. In 1987, Mercedes-Benz introduced its famous 100 D 631 series and a year later the W201 Serie 2 made its debut, which was a compact executive car with a sports sedan body style.
In the 90s, the company introduced the G-Class Wagons and SUVs and numerous new models of the E-Class, C-Class, and S-Class series made their debut. In the 2000s, Mercedes-Benz marked a new era in mechanical supercharging technology and introduced numerous groundbreaking designs and engineering concepts, such as the BlueTec system which was released in 2005 and had the capability of reducing CO2 emissions.
