The Citroen DS5 Hybrid4 has been given new battery management software which improves the efficiency of its diesel-electric hybrid powertrain.
Like the Peugeot 3008 HYbrid4 shown at the Paris Motor Show, the uprated DS5 software improves the amount of energy that can be recovered when decelerating or braking, and better manages the way the DS5’s batteries deliver their power.
That means the DS5 DSign model’s emissions fall from 99g/km to 91g/km, while the DS5 DStyle and DSport versions see their emissions reduce from 107g/km to 102g/km.
Buyers of the DS5 DStyle and DSport models can take the no-cost option of smaller 17-inch alloys, rather than the 18-inch wheels fitted as standard, which drops the emissions for these models from 102g/km to 91g/km.
Despite the update, prices remain unchanged. The Citroen DS5 Hybrid4 DSign model starts at £27,600, the DStyle at £30,100 and the DSport at £32,300. The revised DS5 Hybrid4 model line-up is on sale now.
