There are many misconceptions about three-cylinder engines due to misinformation spread on social media and online forums. The fact is that a three-cylinder engine is theoretically more reliable than a four-cylinder engine because with one cylinder less, you have 25% fewer moving parts. Three-cylinder engines are also theoretically more efficient than four-cylinder engines.
The Citroen Aircross’ 1.2 turbo-petrol engine is the best 1.2-litre engine in our view, offering strong performance and good efficiency. All engines today are compatible with E20 ethanol, and manufacturers have built in greater protection for materials affected by ethanol to future-proof themselves against higher ethanol blends. The bigger worry is Citroen’s service network. Otherwise, the Aircross is a good vehicle, and you can go ahead and buy it.
