Citroen C1 1.4 HDi Rhythm

Diesel engine has impressed in other Citroens in past economy tests. So how does it perform in the baby C1?

There are no gimmicks or gadgets where the C1 is concerned. If you’re trying to work out what it is that makes the little Citroen so incredibly fuel efficient, look no further than the fact it is small, light and has a compact 1.4-litre diesel that generates only 54bhp.

As with the MINI, the Citroen is designed to be a normal everyday car, and so saving fuel isn’t its main focus. That much is obvious from the fact it doesn’t come with stop-start technology – something that is available on certain models in both the C2 and C3 ranges.

However, as is the case with all diesel models in the PSA Peugeot Citroen line-ups, the four-cylinder unit is designed to run on 30 per cent biodiesel – although getting hold of the eco-friendly fuel in the UK is another matter entirely.

As using biodiesel has no effect on the car’s economy, we stuck to conventional diesel for the purposes of our test. On town centre roads, the C1 struggled to make a good impression. Its urban reading failed to match that of either the Toyota or MINI – not a big surprise considering that these models have the advantage of stop-start systems.

But we were expecting the 890kg C1 to get the better of the Volkswagen, Fiat and Renault. However, after only 18 miles it had consumed just over two litres of diesel, giving a reading of 39.3mpg.

This is a long way short of the 53.3mpg official figure claimed by Citroen, but we believe our rush hour crawl is more relevant to most people’s daily driving experiences than the official tests conducted in a laboratory.

Vague pedals and a sloppy gearchange were partly to blame for the poor urban performance. They make the Citroen rather difficult to drive smoothly and progressively.

Still, on our extra urban route, the C1 really came into its own. Aided by its light kerbweight, long gearing and low-rolling-resistance Michelin Energy tyres, it returned 68mpg exactly – a figure that no rival could match. The Citroen breezed up hills and managed to maintain momentum even better than the Panda.

One word of warning, though. While the narrow 155/65 R14 rubber the French company fits as standard helps to save fuel, we found it short on grip in the wet and were far from impressed by its braking performance. On the motorway, the C1 is not the most comfortable or refined car, but it more than made up for this by achieving a credible 62.0mpg. Add that to the other figures we recorded, and it gives an overall return of 60.5mpg – and no opponent could quite live up to that.

741 miles from 33 litres of the sticky stuff.

I purchased my Caldera Metalic Black C1 diesel from new hoping for a pleasant drive and comfortable interior.

Since ownership in June 2007 the car has been totally reliable and very comfortable even over very long distances.

The clutch is a bit too lite for my likeing but the gearbox is slick and a delight to use.

The 1.4HDi Rhythm comes with all the toys, central locking,electric windows, power steering etc just enough kit for enjoyable town driving.

Now that diesel is £5 a gallon once again there is only one other car able to challenge this C1 in the economy stakes and that's the all new Smart ForTwo CDi diesel.

Last September on a journey from my home town of Llandudno in North Wales to Newcastle my C1 achieved some remarkable fuel figures.

Before i set out on my journey i had brimmed the 33 Litre tank and on my return from Newcastle via Carlise and sightseeing along Hadrians Wall i had 485 miles on the clock.

A further weeks driving to work and a tour around Snowdonia eventually saw 751 miles on the clock before the warning buzzer told me there was less than four litres of fuel left.

Now 741 miles on just over 7 gallons of diesel points to well over 100mpg and this was achieved at a constant 50-55mph.

It goes to show that with a very determined driving style and keeping a constant speed diesel cars can achieve some startling fuel economy figures.

The car has just done over 18,000 miles and incredibly cost's around £10 a week to run around North Wales.

It's a car i can heartedly recommend to those searching for a very cheap to run and own proposition.

Compared to the petrol version the C1 diesel is a rare beast but with amazing economy it's worth searching for.
