Mercedes-Benz F100

The Mercedes-Benz F100 was a concept car that Daimler-Benz unveiled at the North American International Auto Show in 1991, built to show innovations in control, design and comfort in passenger cars. It introduced a number of features that later reached production Mercedes models, among them an autonomous cruise control system that appeared as Distronic in 1999, a solar cell roof that appeared on the Maybach 62 in 2002, HID xenon low-beam headlamps in 1995, voice recognition in 1996, tire-pressure monitoring and a rain sensor in the middle and late 1990s, and a chip card in place of car keys that became Keyless Go in 1998. It also anticipated blind spot and lane keeping assistance, which reached series production in 2010.
