Louis Renault developed his first vehicle with a geartrain transmission that was safer and more reliable than chains or belts used by other car makers at the time.
A compressed air starter replaced the hand crank, responsible for numerous injuries.
Renault's six-cylinder 18CV and 40CV models benefited from brakes on the front wheels. The 40CV could be fitted with Louis Renault's patented mechanical servo-brake, for stronger braking action.
The Juvaquatre was the first Renault to benefit from an independent front suspension for better roadholding, consisting of an all-steel monocoque structure, for better protection.
The Lardy Centre was built to conduct tests for all future Renault vehicles. The very first impact resistance tests were carried out here.
Renault set up the Laboratory of Physiology and Biomechanics directed by a physician, to help vehicle design teams develop safer cars. From this moment on, crash tests become a key element of vehicle design and safety engineering.
The R8 was the first compact car to receive disc brakes on all four wheels. This technique was previously reserved for large cars.
Creation of the joint Accident Analysis and Biomechanics Laboratory (LAB), between Renault and PSA Peugeot-Citroën.
The BRV (Basic Research Vehicle) was developed for studies into passive safety.
Renault presented EPURE (vehicle for research into road user and environment protection). It used the concept of a structurally rigid cabin and took into account the impact on pedestrians.
Anti-lock Braking System appeared on the R25.
Driver airbag and seatbelt pretensioners appeared on Clio, R19 and Safrane models.
Mégane introduced the Renault System for Restraint and Protection (SRP1), which revolutionised the seatbelt by adding a load limiter, pretensioner and locking reel.
ABS, driver and passenger airbags appeared across the whole Renault range.
The second-generation Renault System for Restraint and Protection (SRP2) appeared, with driver and passenger airbags, load limiters, pretensioners and headrests with close-up protection.
