Mazda Lightweight Body Structures
Lightweight body structures first seen on the Mazda2 supermini are a key element of the Japanese car maker’s new fuel efficient SKYACTIV models.
The use of high tensile steel coupled to advanced welding and bonding techniques has helped the company shave 100 kilos off each of its new vehicles - the equivalent weight saving of almost two adults.
Allied to other improvements associated with the new SKYACTIV range, the forthcoming generation of Mazda cars will be up to 20 per cent more economical.
Since the introduction of the MX-5 roadster more than 20 years ago Mazda has developed a reputation for making its cars feel light and sporty.In the new SKYACTIV models the proportion of high tensile steel has increased from 40 to 60 per cent.
The result is a body which is eight per cent lighter and 30 per cent more rigid, improving handling and crash protection.
All SKYACTIV cars feature a straight, continuous underbody frame to aid rigidity and unlike other car makers Mazda has not turned to alternative and more expensive materials such as aluminium or carbon fibre to keep weight down.
The first model to wear the SKYACTIV badge will be the new CX-5 compact crossover which is due to go on sale early next year.
The CX-5 – first seen at the Frankfurt Motor Show in September – will also feature a new suspension and chassis designed to deliver improved high speed stability while retaining agility when manoeuvring around town.
Further improvements reduce pitch under braking which not only improves the ride quality but also reduces stopping distances.
