Three trim levels are currently offered: VTR, VTR+ and Exclusive. The cheapest petrol on the market is the 1.6 VTi 120 VTR and the entry-level diesel is the 1.6 HDi 110 VTR.
The 1.6 VTi 120 VTR comes in under £20k, but once you start ticking the boxes on the options list it is quite easy to push the price of the Citroën Grand C4 Picasso far north of that figure.
The 1.6-litre and 2.0-litre oilburning engines were re-homologated in 2010 to improve fuel efficiency, which also helped to reduce the benefit-in-kind tax rates and first year’s VED.
As an example, a Grand C4 Picasso equipped with the 1.6 HDi 110 powerplant and manual transmission will return a claimed 53.3mpg on the combined cycle, equating to CO2 emissions of 139g/km.
Two e-HDI 110 variants put even more of an emphasis on frugality and come equipped with 'micro-hybrid' tech such as stop-start; a reversible alternator that recovers energy during braking; an e-booster function that re-starts the engine with 0.4sec). In VTR+ trim, this Grand C4 Picasso can return a claimed 57.6mpg, and 129g/km of CO2.
In terms of economy, there isn't much to choose between the 1.6 VTi and more powerful (and expensive) 1.6i THP petrol engines, with the former offering a claimed 40.9mpg and the latter 40.4mpg.
