This Citroen offers some innovative three-cylinder 1.2-litre petrol engines that wear a PureTech badge. The fastest of these offers 130PS, skittling the C4 to 62mph from rest in just 10.8 seconds, which is quicker than the 1.6-litre BlueHDi 100 diesel alternative. The Puretech 130 unit will keep at it until it runs out of answers at 124mph, so despite buying a small engine, you're certainly not choosing a weak one. The peak torque figure attests to this, with 230Nm available from just 1,750rpm. Compared to Ford's much-vaunted Ecoboost 1.0-litre in 125PS guise, the Citroen is half a second quicker to 62mph and has another 30Nm of torque in reserve. It's a lightweight motor too, which has all manner of benefits when it comes to corner turn-in and body control. That 130PS engine is joined by a more affordable 110PS version, also fitted with a manual gearbox.
There are also a couple of diesels that are well worth considering. The BlueHDi 100 and 120 engines with a capacity of 1.6-litres deliver maximum power of, respectively, 99PS at 3,750rpm and 120PS at 3,500rpm. The torque at 1,750rpm is 254Nm for the BlueHDi 100 manual unit and 300Nm for the BlueHDi 120 S&S with a 6-speed manual 'box.
As for the driving experience, well, it's a shame that with this generation C4, Citroen did away with the fixed steering wheel boss that was such a talking point in the previous generation version, but apparently a more conventional wheel saves 3.5kg. Despite many of the previous C4's more extrovert features being consigned to history there are one or two quirks remaining, such as the fact that you can tailor the sound of individual warning chimes or the indicators as well as the colour of the instrument lighting. If you're urban-bound, you'll want to know that the pokiest petrol and desel units can optionally be ordered with Citroen EAT6 auto gearbox.
Visual changes made to this car at its most recent 2015 model year update include headlight units that comprise two 3D chrome-finish modules on a gloss black background, with LEDs adding a distinct light signature. The car also features chrome chevrons connecting the headlights and the ribbed bonnet curving into the sides is a neat touch. Moving aft, there are 3D-effect rear light clusters, while a few splashes of chrome and some revised alloy wheels give the C4 quite a sharp look.
Drop inside and you'll notice the 7-inch touch screen straight away, plus perhaps the quality upholstery finishes. The dashboard and fascia are quite conventional, but all of the controls are easy to figure out without recourse to the manual. It's as if Citroen has gone back to concentrating on getting the basics right and you'd have to say on that basis the C4's design is a winner. For example, instead of pouring design resource into a gadget you might use once a year, they've instead designed a seat that's supremely comfortable. Space inside is about par for the class, with rear legroom an issue if you try to seat tall passengers. Headroom is better than average as is access, the C4 only being offered in practical five-door form. There's a large 408-litre boot.
Prices start from around £18,000, which is higher than the figures used to be but still very competitive in the Focus-sized class. There's a choice of 'Edition' or 'Platinum' trim levels. The 7" touchscreen you get on most variants helps to marshal a lot of the minor functions on the dashboard into one clean unit and includes some impressive functionality. The satellite navigation system it can include displays map, speed limits, takes account of traffic conditions, and suggests the most fuel-efficient route. The media player features radio, audio streaming and sync to personal devices. The telephone gets the usual hands-free functionality via Bluetooth and directory access, and also features double-call management.
All variants get features like rear parking sensors, cruise control with speed limiter, 16-inch alloys, leather trim for the steering wheel, handbrake and gear knob, front fog lights and that clever customisable instrument panel. The Citroen also scores when it comes to safety and equipment, with a five-star EuroNCAP rating already under its belt. The C4 scored 97% in the 'Safety Assist' test - at the time the highest score achieved for any vehicle of its type. That's due to the sheer array of driving aids fitted as standard. You get anti lock brakes with Electronic Brakeforce Distribution and Emergency Braking Assistance while ESP stability control is fitted across the range. Six airbags are also fitted, as well as cruise control with a speed limiter. There are elctronic options too, like front foglights with a static cornering function. And a Blind Spot Monitoring system.
The introduction of the latest engines has helped to drive down the cost of ownership. The diesels are a case in point, with these engines drastically reducing nitrogen oxide (NOx) emissions as well as shaving another 4% from the CO2 figure. The Stop & Start technology with an upgraded starter used with the BlueHDi 120 engine helps cut its combined cycle fuel consumption to 74.3mpg and CO2 emissions are an impressive 100g/km.
Go petrol and there are 110 and 130PS 1.2-litre three cylinder PureTech units on offer, delivering 58.9mpg on the combined cycle and emitting just 110g/km of CO2. Other running costs have been driven down as well. Warranty Direct, an independent company not given to any partiality or bias, rated the current generation C4 as one of its most reliable vehicles, scoring better than a BMW 3 Series, a Honda Accord or a Lexus IS.
The Citroen C4 is one of those cars that often gets overlooked despite racking up all kinds of best-in-classes. Here's just one more example. You don't like packing light? Well, you could always do the logical thing and choose the car with the biggest boot in its class at 408-litres. No prizes for guessing what this is. Now that the PureTech petrol and BlueHDi diesel engines are right on the money as far as economy and emissions are concerned, the in-car electronics are right up there with the best and the C4's reliability stats bear any kind of scrutiny you fancy, it's hard not to give this car the thumbs up.
Broaden your mind beyond the usual motoring magazine Golf or Focus recommendations and there are some genuinely talented contenders out there. The C4 just joined that list. It deserves more recognition, so perhaps we can start here.
