One-tank Jags do DBN - return

2012-07-04 08:54

All it takes is one tank! A Jaguar XF 2.2 used only 4.9 lltres/100km to get from Pretoria to the Durban's beachfront - and back.

Two cars from Jaguar SA set out from the Union Buildings in Pretoria on July 1 to make the round trip on a single tank of diesel and both cars made it - though by a tiny margin.

The four-cylinder diesels completed the journey with seasoned economy run expert Roger Rouessart and TV motoring show presenter Marius Roberts driving under the watchful eyes of Richard Carstens from Motorsport SA.


The cars arrived back in Pretoria having covered 1265.8km on a tank: the consumption figures were 64.461 litres (Marius Roberts) and 62.351 litres (Roger Roussaert) over the two-day journey.

David Barns, Jaguar SA brand manager and organiser of the attempt, said: “Traditionally it's a Johannesburg-Cape Town run that's attempted but we wanted to do something different to demonstrate the efficiency of our cars.

"Pretoria to Durban and back is far more challenging in that one has to contend with toll stops and high traffic volumes; however, the cars were up to the challenge and completed the task with little fuss.”

The N3’s multiple toll gates – which increase fuel consumption due to accelerating back up to speed - as well as the city driving elements in and out of Pretoria and Durban, made it a realistic, real-world attempt the "ordinary" driver would be able to replicate. This was proven by Roberts’ 5.1 litres/100km  compared to Roussaert’s 4.9.

Jaguar’s 2.2-litre diesel engine delivers 140kW/450Nm to allow 8.5sec acceleration to 100km/h and a top speed of 225km/h yet the luxury sedan remains frugal at the fuel pumps. Jaguar says the cars received no special preparations and each matched Jaguar’s extra-urban cycle claimed fuel consumption figure.

"Our aim was to demonstrate what Jaguar drivers would be able to achieve for themselves," Barns added. "It was important that we didn’t try to optimise the vehicles or the conditions in any way."

    Best I could get on a trip was 7.5L/100km - which is not bad considering I don't go in for economy driving in any way!!!

      BMW 330i E90; Jhb to Bloem 7,2L/100km. Dbn to Jhb i get 7,7L/100km.

    what speed where they driving at 80, 100, 120????????. I have to say that this was a good test.

  • trevor.bush.9655 - 2012-07-04 10:00

    What a waste of 126L of diesel...add Marius to the mix, BORING AS HELL once again...

      mogo.naut - 2012-07-04 11:29

      Do You know what else is a waste of oxygen?...

  • caponeil - 2012-07-04 10:23

    Would love to do a proper economy run in my Audi A4 . I have managed to get 6.1l/100km traveling 400km doing about 110km/h.

    Funny enough i just did the same trip over the weekend with a VW Polo Bluemotion, driving at 120KM/H one tank down and back up total KM's done was 1311KM on a single tank, driving from pretoria to durban and back. So i dont think this is anything special.

      gregbecker - 2012-07-04 13:39

      If you compare the weight and power output of the Jag's compared to your vehicle it most certainly is special.

      sabongam - 2012-07-04 14:23

      What? You can't even begin to compare...VW Polo Bluemotion which produces about 59kW and weighs 1590kg VS. Jag XF 2.2L producing 140 kW and weighing 3800kg - which is more than double your Polo.Please Artur think before you write.

      Artur - 2012-07-04 14:26

      The point here was not the power but but the distance that can be covered, if you want to use that as an argument then i would use the fact that my tank is half the size as the counter argument.

      bokang.seritsane - 2012-07-04 14:40

      Artur, you not a clever one. Its great your Polo Blue motion can do that trip on such little consumption at a 120km/h, but you need to give credit where its due. The Jaguar XF is at least twice the weight of your Polo, its got much more power and is auto transmission so for it to achieve those figures very is commendable.

      mogo.naut - 2012-07-04 14:41

      Sabongam - SO the Jag weighs more than a HUMMER H2?.. Seems legit.

      mogo.naut - 2012-07-04 14:42

      Artur Besides - The fact is, here we have a car with a similar consumption to a small car. It's a decent sized family car with comfort features such as satnav, a beeeg boot and a comfortable ride - So yes I do think it's "special" if you ask me.

      Press - 2012-07-04 15:19

      Bet you the Polo covered the distances much quicker than the Jag - much more time for other nice stuff than sitting in the traffic burning carbon fuel.

      alan.lockwood.35 - 2012-07-05 10:08

      Guys weight is not the big enemy at 120km/h it is aerodynamics and rolling resistance and gearing. The polo is aerodynamic for a hatchback, the thing is and I stand under correcting that the jaguar is more aerodynamic than the polo. I was expecting the Jaguar to at least achieve 4.6L per 100km.

  • bart.mitchell.393 - 2012-07-04 16:04

    the jag weighs 1745 kg bud,maybe you meant pounds

  • courtney.baird.71 - 2012-07-04 18:49

    they must have pushed these cars.............

  • chris.stange - 2012-07-04 21:42

    I own VW Polo Bluemotion. I recently drove from PE to Bloemfontein and back to Graaff Reniet on tank of Diesal. 1144km on 51 litres. Driving at 120km per hour

  • ronald.ragadza - 2012-07-05 08:12

    This is a great achievement for the big cat. It changes the perception I have about diesel cars.

  • russell.bennett1 - 2012-07-05 14:28

    I'd like to ask one question though - was there ever for one single moment a time during the trip when either of the drivers thought to themselves, "Wow I'm having good fun now!". Thought not...

      alan.lockwood.35 - 2012-07-05 16:49

      You are quiet right the jag is not the most exiting diesel. The Audi a4 3.0tdi is fun.
