Design and Build

The C4 comes both in hatch and C4 X saloon forms. Either way, what this MK3 C4 does beyond any doubt is to confirm that the delineating line between family hatch and compact SUV design is being ever more blurred. Which many folk in search of a compact hatch will think to be no bad thing. Citroen says the crossover cues aren't for crossover purposes. The higher-than-Focus-class-average 156mm ride height is there to offer a high vantage point and better all-round visibility. The matte black-finished wheel arches aren't for arduous tracks but to prevent supermarket car park dings. And there's plenty of signature Citroen design, with stylishly-shaped signature lights and chromed Chevrons that stretch across the car's width. Plus there's and an air intake grille featuring a pattern first seen on the brand's 19_19 concept car. The major change with the lightly updated version of this model is the installation of a much more up-to-date 10-inch HD centre infotainment touchscreen. This is a more responsive, intuitive, and ergonomic interface than the 10-inch display previously used and features customisable widgets as standard. The system also supports HD-quality images from the reversing camera and simultaneous connection for two Bluetooth devices. As before, through the oddly-shaped three-spoke wheel, you view a pared-back version of the quite innovative digital instrument panel used in the brand's C5 Aircross SUV, whose read-outs you flip through here by jabbing the left indicator stalk. For the rear seat, the brand claims best-in-class knee room and offers a wide range of storage compartments. Plus there's a decently-sized 380-litre boot in the hatch version; the C4 X saloon's boot is a big 510-litres in size.

Market and Model

Right, let's get to prices, which are the same whether you choose hatch or C4 X saloon and now start from around £19,500, ranging towards £28,500 for the combustion models. The Hybrid version starts from just over £26,000. The full-electric e-C4 and e-C4 X models start from around £32,000. In the combustion C4 range, there are three trim levels - the usual Citroen ones - 'You!', 'Plus' and 'Max'. Mid-level 'Plus'-spec is based around the usual 130hp PureTech petrol engine with a choice of manual or automatic transmission. With the e-C4 models, the trim options are 'You!', 'Max' and 'e-series'. You'll need the priciest 'e-series'-spec (over £37,000) if you want the latest 54kWh 115kW EV drivetrain with its longer range. Otherwise, your e-C4 will come with the older 50kWh 100kW set-up. To take on key compact similarly-sized EV rivals in the same price bracket, all versions of this C4 need to be well equipped. They are. Nice touches the include LED ambient lighting on the digital instrument panel. Front passengers benefit from access to Citroën's Smart Pad Support, a retractable tablet holder built directly into the dashboard, which enables the front passenger to make the most of time spent on the move. Below this is a Dashboard Tray, a large sliding drawer with a cushioned action. A popular option will be the large electric opening panoramic sunroof. A 10-inch central infotainment screen comes with all C4s, as does wireless 'phone charging and 'Apple CarPlay' and 'Android Auto' smartphone-mirroring connectivity. A superb sound system can be specified too, with Arkamys digital sound processing and 8 speakers. A nice optional touch you might well want to consider is a full-HD camera built into the rear view mirror which can take photos or video stored on a 16GB memory card. Safety-wise, there's no fewer than 20 different driver assistance features, including Highway Driving Assist and a 'level 2' semi-autonomous drive system incorporating Adaptive Cruise Control and Lane Keeping Assist.

Cost of Ownership

So, petrol or electric? Of course, to make a proper judgement, you're going to need to peruse the combustion model efficiency figures - which are very class-competitive. The volume PureTech 130 EAT auto C4 variant returns up to 50.3mpg on the combined cycle and up to 130g/km of CO2. As for the Hybrid 136 DCS6 petrol/electric version, well that manages up to 62.1mpg (similar to the old 1.5 diesel) and up to 107g/km (much better than that old diesel). And the full-electric variants? Well, the Department of Transport tells us that the average motorist in the UK covers 7,400 miles a year, which is the kind of mileage that would cost an e-C4 owner somewhere between £200 and £300 in added electricity charges, powering up from a typical 7.4kW garage wallbox on off peak rates, the variance depending on driving style and different electricity prices (we've assumed 11p per kWh). The same annual mileage in this PureTech petrol model would work out to somewhere between £750 and £820 - and you'd have to factor in more expensive annual garage servicing too. The e-C4 charges at up to 100kW with the 50kWh battery - or at up to 115kW with the 54kWh battery. But charging times are much the same either way. The e-C4 is fitted with a 7.4kW on-board charger, which can rapid charge to 80% in around half an hour using a 100kW public fast charger. At home, the car will charge from empty in around 7.5 hours using a 7kW garage wallbox. That could fall to just 5 hours if you have a 3-phase home electricity supply and have the car fitted with an optional 11kW on-board charger. As usual with an electric car, to take advantage of lower cost off-peak electricity tariffs, you can manage charging times by using the touchscreen tablet in the passenger compartment or by using the provided 'MyCitroen' app. The charging port features a coloured indicator so the user can monitor the charging process - which can also be followed on the 'MyCitroen' app. Whatever your choice of C4, you'll properly want to keep garage costs in check by opting for the affordable 3 year servicing plan that is available at point of purchase. Finally, there's the usual Citroen three year / 60,000 mile warranty. And the e-C4 has its own battery warranty - 8 years or 100,000 miles for 70% of charge capacity.

Summary

All the ingredients for a strong showing are here as this third generation C4 nods to the two currently trending themes of crossover style and electrified power. Yet delivers them within a family hatchback package that traditional buyers in this segment can be comfortable with - quite literally, thanks to the Progressive Hydraulic Suspension set-up. The French maker thinks this sector is 'right for changes' and this car delivers them without getting carried away with innovation, as its C4 Cactus predecessor rather did. And it's obviously significant that within the range lies the brand's first credible full-electric model. Ultimately though, what really matters is that what we have here is a proper Citroen - with all that means. Thank goodness for that.
