Citroen C4 HDI RANGE
Citroens C4 Is A Modern Car In Every Sense But The Jewels In Its Technological Make-Up Could Be The Tried And Tested HDi Engines. Steve Walker Reports
The key thing in evaluating gadgets in cars is whether theyre there serving some useful purpose or simply chucked in as showroom attention-grabbers of questionable practical benefit. All
Citroen C4s have a fixed hub steering wheel, speed limiting cruise control and more digital displays that you could shake your i-Pod at but theres also more. Tick the right boxes and your C4 can feature automatic air-freshener dispensers, Dual Function Directional Headlamps and a Lane-Departure Warning System. You could conceivably order a C4 with a gadget quota to rival the field in TVs Wacky Races but the most beneficial piece of technology to have fitted to your model could well be an HDi diesel engine.

The HDi range opens with an engine that made its debut in the C4, although in fact, its simply a lower output version of the 110bhp 1.6-litre HDi engine thats already appeared elsewhere in the manufacturers line-up. With 92bhp, this 1.6-litre 16-valve unit still delivers a fair turn of speed, particularly lower in the rev range where the 159lb/ft of torque at 1,750rpm makes its presence felt.
At higher speeds, throttle response is less than immediate but 112mph is possible if you persevere. This engine is the budget diesel choice and, as such, will be bought as much for its claimed 60mpg fuel consumption as its performance credentials. Next up is that 110bhp 1.6-litre HDi engine we just mentioned and while the official performance figures arent a massive improvement over the 92bhp engine (11.
2s 0-60mph and 119mph top speed instead of 12.5s and 112mph) there is noticeably more urge off the line. Maximum torque here is 177lb/ft at 1,750rpm and average fuel economy is said to be 60mpg identical to the less powerful 1.6-litre engine.
Both of these 1.6-litre units are extremely quiet, whether youre inside at the wheel or standing outside admiring the view. The ultimate C4 HDi is the 138bhp 2.0-litre 16-valve version and its less quietly spoken than the 1.
6-litre contingent. That mild extra gruffness, however, is a price that the keen driver will be happy to pay for a 9.7s 0-60mph sprint. This powerplant feels significantly more muscular at lower engine speeds thanks to a brutal 236lb/ft of torque at 2,000rpm and its more responsive higher in the range too.
The other big factor that will draw buyers in the direction of the largest HDi is its gearbox. The 5-cog set-up thats matched to the 1.6-litre units feels loose and aimless in the worst
Citroen traditions but the 6-speed box you get with the 2.0-litre is a big improvement.
The 2.0-litre manages a creditable 52mpg average fuel consumption and like all the C4s HDi engines, its compliant with the Euro IV emissions regulations.
"Despite all the new hi-tech gadgets, the familiar HDi diesel engine is the most important part of the C4s technical armoury."
The C4 range is split between the 3-door and 5-door bodystyles, or Coupe and Hatchback as Citroen would have us call them. Adhering to the trend in the wider motor industry at the moment, the two derivatives each display their own unique character, reflecting the specific markets at which theyve been targeted. The C4 Coupe is a strikingly styled car by any standards and its edgy lines are accentuated when viewed in comparison to most rival 3-door hatchbacks. The chiselled rear, the stubby chevroned nose and the long arcing roof combine to cohesively sporty effect.
The Hatchback is less extrovert but isnt without its charm. The front ends of both vehicles are identical but as you progress rearward, where the Coupe becomes progressively sharper the family-orientated Hatchback goes all curvy on us. Citroen can call the two C4 bodystyles what they like, both have hatchbacks and both yield similarly decent amounts of luggage space (320 and 314-litres in Hatchback and Coupe respectively). Where as the 5-doors hatch boasts a wide aperture, however, the 3-doors tapered rear can only accommodate a more restricted opening.
The C4 has excellent aerodynamics with a drag coefficient of 0.28 shared by both bodystyles and the two C4s also share similar on-road dynamics. Theyre characterised by a smooth, comfortable ride and handling thats balanced but doesnt quite trouble the class leaders in terms of sheer fun. First impressions on climbing aboard the C4 are that this is going to take a bit of getting used to.
The steering wheels hub doesnt turn with the wheel itself. It stays fixed in position as you round corners, the digital rev counter and the warning lights situated on a console above it. Any other information you might require is then available from a clear centrally mounted multi-function display on the top of the dash. Its all a bit unusual but, remarkably, after a few minutes on the road you really dont feel that anythings amiss.
The fixed steering wheel centre houses controls for the stereo, cruise control and the multi-function display but because it stays still, all are nice and easy to put your finger on. More importantly, the static hub means that an airbag can be fitted thats optimally shaped to give the best protection in an accident. Normal steering wheels must have round airbags because its uncertain which position the hub will be in when the bag is deployed. Overall, the clean, uncluttered dash, the quality soft-touch materials and the clear multi-function display are C4 strong points.
Well built though it is, the car doesnt feel quite as solid as a Focus or Golf and rear visibility is restricted by the Coupes unorthodox rear window. C4 buyers have a range of trim levels to choose from split between the Coupe and Hatchback bodystyles. If we limit this to the HDi models, the entry-level is the £12,695 5-door LX with the 92bhp 1.6-litre engine and the range topper is the 5-door 2.
0-litre HDi Exclusive. The priciest diesel Coupe is also the quickest - the 2.0-litre HDi VTS. The C4 pricing looks attractive, particularly given the level of technology contained within the package.
Its a good-looking, safe, well-designed car that heads its class on originality. The HDi engines provide performance and economy in generous measure, depending on your requirements. They probably represent the pick of the C4 range.
