Mercedes-Benz's parent company, Daimler, manufactures the Smart line of vehicles within its Mercedes-Benz car division. It does not, however, advertise Smart as a Mercedes-Benz product, keeping it as its own separate brand. As of September 2015, Smart sells six models of car in the United States including gas, electric and convertible options. All of Smart's models in the United States are based on its two-person Smart ForTwo body style.

In 2014, Daimler sold 92,000 Smart cars worldwide. The company redesigned the Smart ForTwo for the 2016 model year. The redesign includes a large grill, a wider stance and an overall appearance more similar to a traditional hatchback than that of its predecessor's, according to Edmunds. Smart offers four gas-powered models in the United States, all of which come with a three-cylinder, turbocharged 89 horsepower engine. Smart's two electric models are still based on the previous generation of Smart ForTwo. They come as either a hard top or convertible and have an average range of 68 miles while taking about six hours to charge fully.

In addition to its Mercedes-Benz brand of luxury vehicles, Daimler manufactures a wide variety of automobiles. These include Freightliner trucks, Thomas Built school buses, Fuso trucks, Western Star trucks and its own Mercedes-Benz branded trucks, vans and buses.
