Next Generation Advanced Compatibility Engineering (ACE)
The newly designed Jazz has been improved in every aspect, starting from the body structure. The new design has a lighter but stronger platform with tighter body tolerances and a quieter cabin. Overall size has only marginally changed, but interior space has been greatly improved. The new Jazz also utilises next generation Advance Compatibility Engineering (ACE) body structure – enhancing frontal collision performance and improved occupant safety.
Next Generation ACE Body Structure
The new Jazz utilises the next generation version of Honda's proprietary Advanced Compatibility Engineering™ (ACE) body-structure technology to enhance occupant protection and crash compatibility in frontal collisions. The improved design uses more high-tensile strength steel to distribute crash energy more evenly throughout the front of the vehicle. A high-efficiency load-path floor structure is designed to more efficiently disperse and absorb collision energy; this is achieved with the revised design including a structural member which is fitted at the same time as the fuel tank.
This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment. Internationally it has helped the Jazz achieve excellent ratings in crash testing by the IIHS and the NHTSA, and a 5 star ANCAP result. Our own Jazz RS(6MT) has received 5 star JNCAP. ACE also helps minimise the potential for under-ride or over-ride situations that can happen during head-on or offset frontal impacts with a larger or smaller vehicle.
Weight & Rigidity Improvements
Since moving the mass of a vehicle requires energy, overall fuel efficiency can be improved by reducing its weight. Reducing vehicle weight must be balanced with other factors such as structural integrity, ride and handling characteristics, low noise, vibration and harshness (NVH) and occupant safety.
Weight reductions in the new Jazz include the extensive use of super-high-tensile strength steel that provides increased structural strength with less material. With 23 percent of the body structure being made with these high-grade steels – 780 megapascals of higher yield strength – the body is more than 20kg lighter than the previous Jazz but also more rigid. Further kilos have been shaved from the weight of the doors with a manufacturing process that integrates the door outer skin, inner panel and sash, press-forming them together. A further 4kg reduction in body weight was realised from the inner frame and body assembly process.
