Turkish Test of Peugeot 407 1.6 HDi Yields 3.68 l/100km (64 MPG US)

5 July 2007

In a fuel consumption test carried out under real traffic conditions while driving from Istanbul, Turkey to Antalya and back, a Peugeot 407 1.6 HDi diesel model consumed 3.68 l/100km of fuel (64 mpg US).

The 407 1.6 HDi’s NEDC fuel consumption figures are 5.3 liters/100 km (44.4 mpg US) in combined cycle and 4.4 liters/100 km (53.5 mpg US) for the highway. This test again highlights the difference driving conditions and skill can make.

The total distance covered was 1,417 kilometers (880 miles) and the test was officially monitored and approved by the Turkish Federation of Automobile Sports (Tosfed). The average speed of the trip was approximately 68 kph (42 mph).

The fuel tank was filled in Istanbul under the supervision of Tosfed officials and sealed off. Tosfed officials followed the Peugeot 407 test car during the entire journey with another car.

When the journey was completed in return to Istanbul, the tank was filled in the same way together with the Tosfed officials and the fuel consumption was calculated. Tosfed officials also had a tripmaster instrument in their vehicle to measure the distance driven, the kind of instrument used to measure the stages in rallies.

The Peugeot 407 was driven by Erkan Altınsoy who is an ex-motoring journalist. About one year ago, he made a similar but unofficial test by driving his car, a 2004 Peugeot 307 1.4 HDi, from Istanbul to Antalya (702 km) with an average fuel consumption of 3.77 l/100 km.

nothing special

if i drive below 90kph i get the same fuel economy;

my problem is if i got faster then 100kph

What a coincidence, I just got back from Turkey.
Driving in Turkey is not for the faint-of-heart. The first thing you notice in Istanbul is the smell of diesel. 68mpg is pretty amazing considering how mountainous it is between Istanbul and Antalya.

I wondering if he used every trick in the hyper-mileage bucket? Did he draft behind large trucks, and cruise at the very bottom of the RPM range for his highest gear? I'm guessing that played a part. Still, it's great to see the difference driving slower makes.

you don't need tricks,
just use a modern french, italian, german diesel
below 100hp and below 1,5 of size and you get easily below 4l/100 if you don't drive faster then 90kph;
