Mercedes Mcnab

- Daimler invented the float carburetor which was used until replaced by fuel injection
- The "drop chassis"—the car originally designated the "Mercedes" by Daimler was also the first car with a modern configuration, having the carriage lowered and set between the front and rear wheels, with a front engine and powered rear wheels. All earlier cars were "horseless carriages", which had high centres of gravity and various engine/drive-train configurations
- The first passenger road car to have brakes on all four wheels (1924)
- The "safety cage" or "safety cell" construction with front and rear crumple zones was first developed by Mercedes-Benz in 1951. This is considered by many as the most important innovation in automobile construction from a safety standpoint
