Citroen C4 WRC

Like its glorious predecessor the Xsara, the Citroën C4 WRC is a car equipped
with four-wheel drive, a 2-liter turbocharged engine coupled with a 6-speed
transverse gearbox. What‘s different about the C4 WRC is that it‘s longer than
the Xsara, eat over 4.20m, thus benefiting from an increased width from 1.77m to
1.80m. This change theoretically gives it better cornering stability. As regulation
also requires, the use of electronic driving aids is limited, the same as with the
Xsara‘s 2006 configuration. Still within the framework of regulatory budget
reduction, the C4 WRC‘s sub-assemblies should also be more reliable and built
to last longer, including the engine, gearbox, front differentials, center and rear
suspension etc.
The test vehicle was used to test the technology and for set-up runs and was
unmarked.
