THE NEW CITROňN C4: POSITIVE POWER

November 2010  

POWER & DYNAMICS

On the road, the new C4 combines the highest standards of ride smoothness and responsive handling for an enjoyable driving experience.  The suspension settings are tailored to the power and torque of the different engines, which contributes to new C4’s class-leading levels of on-board comfort.
With MacPherson-type front suspension, rear suspension with a flexible transverse beam and speed sensitive hydraulic steering with an electric pump, the running gear’s proven features are a perfect fit with the vehicle’s characteristics.  The CitroŽn C4 also delivers excellent roll control and exhibits sharp reactions, notably in emergency manoeuvres.
The new C4 is offered with a range of BMW co-developed petrol engines, highly efficient HDi diesel engines and gearboxes that help maximise fuel economy.

New C4 offers:

  • Four diesel engines - HDi 90, HDi 110, e-HDi 110 & HDi 150. 
  • Three petrol engines - VTi 95, VTi 120 & THP 155.
  • The THP 155 & e-HDi 110 are both mated to a 6-speed EGS gearbox.
  • The HDi 110 & HDi 150 are mated to a 6-speed manual ‘box.
  • The VTi 120 is available with a 5-speed manual or a 4-speed automatic transmission.
  • The VTi 95 & HDi 90 both come with a 5-speed manual ‘box.

All engines are Euro 5 compliant, all diesel engines are equipped with a particulate filter (DPFS) and all manual models are fitted with a Gear Efficiency Indicator (GEI).  The 6-speed EGS transmission has an ‘Auto’ setting and delivers lower fuel consumption than an equivalent manual transmission.

e-HDi

New C4 VTR+ and Exclusive models are available with CitroŽn’s innovative new micro-hybrid e-HDi system with EGS transmission, which delivers up to 67.3mpg over a combined cycle and just 109g/km of CO2.
The e-HDi powertrain consists of a refined and efficient 1.6HDi 110 diesel engine fitted with a Stop & Start system featuring a second generation reversible alternator.  An e-booster system allows instantaneous and whisper silent engine restarts in just 400ms - twice as fast as a manual key restart and 30% faster than with a reinforced starter.  The electronically controlled alternator uses regenerative braking to recover energy and the EGS gearbox features optimised gear ratios.  The system even stops the engine before the car comes to a complete halt - from 5mph during deceleration.  The e-HDi system can improve fuel efficiency by up to 15% in urban environments and reduces CO2 emissions by around 5g/km.
Models with 16” wheels, including the e-HDi VTR+, feature low rolling resistance Michelin Energy™ Saver tyres, which help to reduce fuel consumption and reduce CO2 emissions by up to 5g/km compared with standard tyres.
