CITROEN is heralding a new range of super frugal petrol engines as the latest advance in its on-going ‘Creative Technologie’ quest.
Smaller, lighter, more efficient and a whopping 25 per cent cleaner than before, the new powerplants are called PureTech and make their UK debut in the C3 and more sporty DS3 models.
The French manufacturer says that this new family of three-cylinder units also has equivalent or superior power compared with the previous generation engines.
Two different capacity versions have been developed - a 1.0-litre and a 1.2-litre with power ranging from 68bhp to 82bhp, and depending on the model and tyres fitted, combined fuel consumption is between 65.7mpg and 61.4mpg with CO2 emissions from 99 to 107g/km.
The PureTech option already available in C3 and DS3 models is the 1.2-litre VTi 82 unit boasting more power than the 1.4-litre engine it replaces.
And the advances translate to a 7mph higher top speed, fuel economy up by 15.7mpg to 62.8 and emissions down by an impressive 35 per cent to 104g/km.
Next year sees the arrival of a 1.0-litre VTi 68 engine for the C3 line-up and again we are talking more power than the outgoing 1.1-litre powerplant, a 5mph top speed improvement, impressively better fuel economy at 65.7mpg and emissions way lower at 99g/km.
The gains are due to the use of a three-cylinder engine - as opposed to one with four cylinders – which has less energy loss through friction, fewer moving parts, a lower weight and more compact dimensions, all of which cut fuel consumption.
In fact by reducing the number of cylinders, as well as redesigning several components, the weight loss compared with the previous engines is around 20 per cent.
