Car drives coast to coast on one tank of diesel

A Peugeot 308HDi drove across South Africa on a single tank of diesel last month. The car, driven by two former rally drivers, Andrew Carter and Spotti Woodhead, did the 1,700km trip from Port Nolloth, on the west coast, to Umhlanga, on the east coast, with an impressive fuel consumption of 3,4 litres per kilometre.

“The route is incredibly challenging because it climbs more than 1,800 metres and visits substantial cities like Bloemfontein where there is traffic to contend with. We literally didn’t know we would make it until we arrived at the finishing line,” said Carter.

Peugeot says it devised the Coast2Coast Challenge to showcase the ultra-efficiency of the medium-sized hatchback 30, and highlight the need for motorists to drive fuel efficiently in order to reduce their impact on the environment.

Mike Wilson, Peugeot Motors South Africa’s marketing manager, said: “We knew the 308 HDi was incredibly light on fuel, but we were pleasantly surprised when it pulled up near Durban on the same tank of fuel it had set off with on the other side of South Africa.

“The success demonstrates that when technology designed with the environment in mind is allied to a fuel efficient driving style, the increased distance between refuelling stops can be startling.”

Carter was a guest on Redi Direko’s show on Talk Radio 702 this week and was talking about the fuel-efficient driving techniques he and Woodhead had used on the trip. To a non-petrol head like myself some of them sounded pretty technical, for instance, try to drive your car at maximum torque because that’s when your engine is at its most efficient (that one sailed way over my head, but apparently you can find out your car’s maximum torque in the user’s manual).

There were a few tips that I did understand, though: firstly, you need to learn to be patient behind the wheel (not an easy thing for a Joburg driver), get up to the top gear as quickly as you can without making your engine work too hard – in other words, be gentle on the accelerator, don’t stamp the pedal onto the floor.

Although fuel-efficient driving is not about speed, Carter said the car did reach 130km/h at times. He said they tried to pick up speed going down hills so that the momentum could take them most of the way up the other side without having to put much strain on the engine.

They didn’t take that long to do the trip: they left Port Nolloth on Monday October 13 and arrived in Umhlanga on Wednesday October 15.

The Coast2Coast 308 is apparently 95 percent recyclable and Peugeot has planted trees in the Orange Farm informal settlement near Johannesburg to offset the challenge’s carbon emissions.

Fuel consumption figures at your fingertips

Here’s good news for anybody out there who can still afford to buy a new car and is more interested in fuel consumption than how many seconds it takes to reach 100km an hour or whether your car is bigger than any of the others on the road. All new vehicles will now have to be labelled with their fuel consumption and carbon dioxide emissions at the point of sale.

The New Vehicle Comparative Fuel Economy Labelling System was launched on July 1. All new vehicles are now tested under the same conditions to determine fuel efficiency and the National Association of Automobile Manufacturers of South Africa (Naamsa) has compiled a comprehensive list of the fuel efficiency levels of more than 1,200 cars sold in South Africa.

Once upon a time, before the fuel prices began their giddy ascent, people used to go for diesel vehicles because they were more fuel efficient. But things have changed apparently, with diesel now more expensive than petrol, people don’t think it’s worth paying the extra  “R20,000 or R40,000” for a diesel model, said a motoring editor quoted in the Sunday Times this week. Diesel vehicles get more kilometres per tank in long-distance driving, but they don’t make much difference when driving around town, the editor said.

Fuel consumption and emissions data are available on the Naamsa website – although not as a comparative table which would allow you to compare cars. You have to select cars by the make and model and then only can you see the data.

Much more useful, though limited, is the table the Sunday Times [please note that this link no longer works] printed this week showing the 17 top fuel savers and 12 biggest gas guzzlers. The (cheapest) petrol car with the lowest fuel consumption is the Citroen C1 (4.6 litres/100km) , according to the table. At the other end of the scale are the Jeep Grand Cherokee 6.1 (16.1 litres/100km) and Range Rover (16 litres/100km).
