· Endurance testing on the DaimlerChrysler proving ground in Papenburg: Extreme
acceleration and braking manoeuvres with a high proportion of full load operation, making extreme demands on the cooling and fuel delivery systems.
The switch to R - Design spec also adds suspension tuning (a double - wishbone front end,
and an integral - link rear set - up with optional air suspension) which is good, especially considering the chassis
and suspension in the ’18 XC60 has already been tweaked to help keep the body as neutral as possible both in the bends
and during
braking and acceleration manoeuvres.
