CHASSIS

The chassis development of the Honda CR-Z was always going to be a cornerstone of the character of the car. From the outset, the basic platform was going to be shared with the Honda Insight hybrid, but with significant changes in length, track width, components and settings.

The most significant change to the platform, is the reduction in wheelbase by 115 mm to increase the agility and reduce the overall length of the CR-Z by 310 mm. Along with the reduction in wheelbase the track width has been increased by 20 mm (front) 25 mm (rear) to give greater stability.

The basic architecture of the suspension for the Honda CR-Z is similar to the Insight that it shares its platform architecture with. Changes have been made to components to suit the sporting nature of the Honda CR-Z and maximise driver enjoyment. The springs, dampers and anti-roll bars are unique to the new coupe to suit the different characteristics of the Honda CR-Z.

To complement the wider track and reduce weight, the lower arms of the front MacPherson strut suspension have been formed from forged aluminium, rather than the pressed steel used for the Insight arms. These aluminium struts are in total 4 kg lighter than the steel components, as well as being stronger, to support the greater forces generated by the increase in track width and tyre size.

The rear suspension is an H-shaped Torsion beam, which is built along the same design concept as the Insight in providing excellent control of the rear wheels, while creating room for the low mounting of the IMA batteries and control unit. The mounting of the IMA system's batteries below the boot, and the low overall height of the Honda CR-Z has clear handling benefits, lowering the centre of gravity for the coupe. The trailing arms in the Honda CR-Z are modified to increase track width and increase strength.
