Fuel efficiency champion in terms of Citroen Grand C4 Picasso running costs is the 1.6-litre e-HDi 90 Airdream diesel model with the ETG6 semi-automatic transmission. Citroen claims an average of 74.3mpg with emission of just 98g/km of CO2, providing inexpensive road tax costs.

Citroen expects the VTR+ trimmed e-HDi 115 with a manual gearbox to be the best-seller in the range. By comparison, it’s claimed to achieve 70.6mpg with CO2 emissions of 105g/km.

Citroen claims that at just 98g/km of CO2, the Grand C4 Picasso e-HDi 90 Airdream ETG6 has the lowest emissions in the seven-seater people carrier class.

By improving the car’s aerodynamics and engine efficiency, as well as a 110kg weight reduction, emissions are an average of 30g/km lower across the range.

With the car only just launched, it’s too early for accurate predictions about Citroen Grand C4 Picasso’s reliability.

As it’s based upon an all-new platform there are some unknown quantities, but the majority of the engines have already seen service in a variety of Citroen and Peugeot products without any significant issues.

Citroen will be hoping that niggling faults which have dented the outgoing Grand C4 Picasso’s reliability reputation will be banished from the new model.
