The new engine uses the Airdream signature – a name first used on ultra-efficient diesel engines in the Citroen C3 range, which was capable of returning road tax-free levels of CO2 emissions.
While this is not the case with the Berlingo van, the micro-hybrid diesel engine does return an impressive 60.1mpg of fuel economy, a figure more likely to appear on a frugal hatchback than a van.
It also returns 123g/km of CO2 emissions making it the greenest ever Citroen Berlingo van sold in the UK.
For drivers, this means significantly lower driving costs. Citroen says the new Citroen Berlingo Airdream will use 15 per cent less fuel than previous versions in the city.
This is mainly due to the e-HDi ‘micro-hybrid’ technology. Although the car uses a conventional diesel engine, it also boasts Stop & Start technology capable of switching the engine off when the car is stationary in traffic and instantly back on again when the brake is released.
The engine restart system is aided by an electric ‘booster’, which explained the ‘e’ part of the HDi engine’s name.
This, alongside regenerative braking – a system where energy is stored from braking to power electrical components of the van such as the air conditioning – helps to keep fuel costs down to a minimum.
The engine also has the benefit of qualifying for Euro 5 standards, a set of CO2 emissions (and other pollutant) targets for all new vans sold across Europe.
The new Citroen Berlingo Airdream option is available with a choice of five-speed manual or six-speed automatic transmissions with prices starting from £12,795 before 20 per cent VAT is added.
