The active hood has been around on European cars since 2005, so not a new feature
The Jaguar XK was the first car to feature a deployable bonnet pedestrian safety system in 2005, although the system was first unveiled by Honda in a concept vehicle in 2004 and introduced in a production model in 2008. The system uses pyrotechnic actuators to lift the rear of the bonnet upon impact with a pedestrian, creating a cushioning effect to reduce head injuries.
Jaguar XK (2005): This was the first vehicle to publicly unveil the production system, which was designed to meet new European safety legislation. The system automatically "pops" the hood up a few inches to create a cushion between the pedestrian and hard points in the engine compartment.
Honda (2008): Honda unveiled its "Pop-up Hood System" technology in 2004 and incorporated it into a production vehicle in 2008. Honda's system uses sensors in the bumper to detect an impact, then an actuator raises the rear of the bonnet by about 10 centimeters.
General Motors (2007): GM introduced its active hood system in 2007 in the European market. This system works at speeds between 25 and 48 km/h (16-30 mph) and is designed to reduce pedestrian fatalities.
Buick Regal (2017): Buick made the active hood standard in China with the new generation Regal in 2017.
