• All models have great fuel consumption
• Citroen offers servicing plans up to three years
• Low tax for all models

Since 2014, the C4 Cactus has earned a great reputation for low running costs – which ever model you choose, the fuel consumption is excellent. The lightness of this car means it’s efficient, and as a consequence, you get low emissions and high mpg figures.

Depreciation promises to continue Citroen’s ability to lose value at a faster-than average rate – according to CAP a C4 Cactus BlueHDi 100 Feel that costs £18,840 new (at the time of writing) will be worth £5,375 after three years and 50,000 miles. That works out at a retained value of 28.6%.

The fuel consumption figures range between 61.4 (for the soon-to-be phased out PureTech 82) and 83.1mpg (for the BlueHDi 100 on 16-inch wheels). In  the real world, that will equate to an easy 50mpg for the petrol and 60mpg for the diesel when driven gently.

• All models have impressive CO2 figures and achieve Euro 6.2
• Light weight means smaller engines all round
• No plans for electric or hybrid versions

Despite being a facelift of a car that’s been around since 2014, the Citroen C4 Cactus emissions are still very impressive. Put this strong performance down to a lightweight body and efficient PureTech engines. In fact, even the worst CO2 offender, the PureTech 130 petrol with EAT6 transmission still manages to put out only 110g/km.

The BlueHDi 100 puts out the lowest emissions, with 90g/km of CO2 on 16-inch wheels (as opposed to 92g/km on 17s), for a combined fuel consumption figure of 80.7mpg. That’s less impressive than the greenest version of the outgoing Cactus, but still a very good performance.

• C4 Cactus reliability better than you might expect
• Tried and tested tech across the whole PSA range
• Some electrical gremlins, now fixed under warranty

Despite having a reputation for unreliabilty, the Citroen C4 Cactus has put in a good overall performance since its launch in 2014. There’s no reason to assume that this will change, given that this one is a facelift with little in the way of brand-new technology.

There have been some reports of touchscreen failures, all of which have been sorted under warranty. The old model was subject to four recalls between 2014 and 2018, all of which were to attend to minor problems.
