Engine is responsive but gets noisy on higher revs losing some power. Good torque over a wide range of rpm. The auto transmission box shifts well. Quiet. Braking is good, thanks to an all disc setup. Suspension automatically adjusts height in different road conditions. Taking the C5 round corners at higher speeds reveals rather significant body rolls. Putting it into the Sports mode reduces that a little.
Alot of adjustments controls. eg. steering wheel can be moved, electronic seat adjustments. Pretty standard in european cars. Large boot space. Most notable features includes its 7 airbags, but that couldn't be tested. I feel safe however. ;) Overall the C5 is a balanced, fully featured car.
