C219, is based upon the W219 platform, a W211 E-Class spin-off
that is stretched by six inches (152 mm).

Frankfurt Motor Show where it was named the Vision CLS concept.
The production version CLS 500 made its arrived at the 2004

The first-generation CLS was fast, safe and popular. It featured
an array of safety equipment, like sensors which detected and
reacted to an imminent collision by tightening the seatbelts,
adjusting the front passenger seat positions to better cope
with an impact, and automatically shutting the sunroof. In addition
to front airbags, there are side-impact airbags in the front
seats, and curtain airbags throughout the vehicle.
