2012 Citroen C5 Review and Informations
Recognised as one of the best-styled models in its segment, the Citroen C5 has been subtly upgraded. The changes enable the car to keep all its character while making it immediately visible and recognisable out on the road.
LEDs have been added under the headlamps. Active day and night and combined with a light guide, they subtly strengthen the car’s light signature. The headlamps retain all the existing functions, including xenon dual-function directional lights and corner lights.
The rear lights get a new ‘Dark Crystal’ treatment with clear glass in the central section.
A new engine is making its appearance in the Citroen C5 range, a new-generation 2.2 litre powerplant bringing across-the-board progress on power, torque, silence, fuel consumption and CO2 emissions. Upgrades made to this engine are in line with those already used on other diesel units in the range (4- cylinder, 1.6 l and 2 l, 3 l V6). They chiefly concern the common rail system, now third-generation, with maximum injection pressure up to 2,000 bars, combustion chambers retaining ECCS (Extreme Conventional Combustion System) technology, and a lower compression ratio (16 to 1), for enhanced operating silence and lower emissions. Engine feed is still via two turbochargers, whose parallel sequential set-up provides plentiful torque from the lowest engine speeds.
The Citroen C5 HDi 200 DPFS develops 150 kW EEC (204 bhp) at 3,500 rpm and maximum torque of 450 Nm to 2,000 rpm. Mated to a 6-speed automatic gearbox, the engine provides remarkable performance, with a top speed of 230 km/h (225 km/h for the Tourer), 0-100 km/h in 8.3 seconds (8.6) and combined-cycle consumption of 5.9 l/100 km (6.1). The saloon emits 155 g/km of CO2 and the Tourer 159 g/km. Like the Citroen C5 HDi 240 DPFS, the new version stands out visually with its chrome-finished double tailpipe.
Citroen C5 VTi 120 WITH EGS6, THE NEW PETROL POWERPLANT The Citroen C5 range is now available with a new petrol engine mated to the 6-speed electronic gearbox system (EGS6). Developed with the BMW Group, the 1.6 litre powerplant develops 88 kW EEC (120 bhp). Mated to the EGS6 gearbox, with wheel-mounted paddles, combined-cycle fuel consumption is 6.2 l/100 km and CO2 emissions are 144 g/km.
The Citroen C5 inaugurates the new micro-hybrid technology that will be widely applied to numerous models in the range. Initially it will be available with the HDi 110 DPFS version equipped with the EGS6 electronic gearbox system with steering-wheel paddles and low rolling resistance tyres.
The micro-hybrid technology consists of a second-generation Stop & Start system, which retains an alternator-starter, or reversible alternator, boasting enhanced performance. Power has been increased on the first-generation system, by 70% to 2.2 kW, and now includes a power electronics unit. Fitting the system on a diesel engine constitutes a world first for a passenger car.
Start-ups take just 400 ms, half the time of a starter, and remain completely transparent for users. Noise is eliminated through the use of a timing belt rather than the gears of a conventional starter. Vibrations have been eliminated – at start-up and cut-out – by using a twin-mass engine flywheel and a sealed air regulator and by attaining slowdown speed faster.
An onboard network assistance system, called e-booster, boosts the electricity supply of the alternator using super-output, temporarily adding to the power of the battery. This set-up has several advantages, namely:
•an increase in transmitted energy, improving start-up capacity for temperatures of as low as -5°C;
•onboard network support via complete transparency on the energy required by the alternator, to maintain the performance of the lights, windscreen wipers and radio;
•a function that optimises battery charge and super-output through energy recovery when drivers take their foot off the pedal or slow down, with a slight increase in the engine brake.
The Citroen C5 e-HDi is also equipped with an optimised watertight battery sized for up to 600,000 restart cycles. Engine suspension has been enhanced on the Citroen C5 for increased comfort during stops and re-starts.
The new equipment considerably reduces the Citroen C5′s fuel consumption and CO2 emissions. Over a combined cycle, the diesel model consumes 4.6 l/100 km and emits 120 g/km of CO2. In an urban cycle, fuel consumption and CO2 emissions are up to 15% lower.
Citroen eTouch is now available on the C5. Comprising a package of services including the emergency and assistance calls, Citroen eTouch also proposes a virtual maintenance manual and an Eco-Driving service accessible via the MyCitroen personal area on the web. For calls, Citroen eTouch works completely independently. The system is equipped with a GPS module and a SIM card, with no need for a call plan and unlimited over time. The vehicles features two buttons, "SOS" for emergency calls (the call is also triggered automatically in the event of impact) and "Double Chevron" for assistance calls. The emergency call gets emergency services to customers faster, for accident victims and bystanders alike. The two services are free and available 24-7.
