Citroën has revealed updates to the Plug-in Hybrid variants of its C5 X and C5 Aircross to deliver greater range and reduced CO2 emissions. 

The Plug-in Hybrid C5 Aircross previously came with a 13.2kWh battery, though for 2022 has been upgraded to a larger 14.2kWh unit. Citroën claims the change will deliver an extra 41 miles of WLTP-certified pure-electric range - an increase from 33 miles.

This brings the car’s benefit-in-kind tax rate down from 12 to eight percent.

The larger battery also sees a marginal reduction in CO2 emissions - down from 32g/km to 29g/km. 

The 1.6-litre four-cylinder engine remains unchanged, and is assisted by an electric motor to produce a combined power output of 222bhp. 

The flagship C5 X uses the same engine and electric motor as the C5 Aircross to produce 222bhp, and retains the 12.4kWh battery as the current C5 X, though now supports an improved minimum charge threshold. 

As a result, the car now offers up to 39 miles of electric only WLTP certified range, with CO2 emissions reduced to 27g/km. 

Unlike the C5 Aircross, the C5 X misses out on the BiK tax reduction, remaining at the 12 percent tax band. 

The New C5 Aircross Plug-in Hybrid version is priced from £35,935, and is available in Sense Plus, Shine or C-Series Edition trims.

Meanwhile, the new C5 X Plug-in Hybrid variant is priced from £36,720, and can come in a choice of trim levels: Sense Plus, Shine and Shine Plus.
