how it's built, how it's developed?

Let us show you. This is Trucks' Anatomy.

Fuel accounts for roughly one third of the total operating costs

in the long-haul business.

In this episode of Trucks' Anatomy, we will focus on fuel efficiency

and how Volvo Trucks' fleet management system Dynafleet

can be used to ensure that every drop counts.

A number of factors can affect a truck's fuel consumption,

including tyre pressure, weight, axle alignment, weather conditions

and the overall condition of the vehicle.

However, one of the biggest factors is actually the driver.

Right. How the vehicle is driven is key when it comes to fuel efficiency.

So, to see just how much the driver can reduce fuel consumption,

Andrew Low, Volvo Trucks' driver development manager,

invited me for a small fuel-saving contest.

And, as it happens, our showdown today will take place at the very same track

as this year's Drivers' Fuel Challenge final.

The track measures 7km and the rules are simple.

Finish the circuit in under 15 minutes and obey all traffic rules.

And the contenders are: me, Peter Sundfeldt,

former race-car driver and automotive journalist,

Andrew Low, Volvo Trucks' driver development manager,

a real expert when it comes to fuel-efficient driving.

Right, Andy.

I'm ready with the stopwatch and we've reset the systems.

- So I'll just... - Start the truck, yeah.

Make sure we're in neutral first. Now the clock is running.

- As soon as the engine's started. - And we're off.

I've been driving a couple of practice runs

and got some driving advice from Andrew,

but now the challenge is on.

It's like driving a motorcycle, right? I mean, you think ahead.

The techniques are very similar.

What we're trying to achieve is in some ways slightly different,

but braking hard into corners and things like that

is what we're trying to avoid.

Now we have a stop.

We're forced to do a stop here. We're joining the main road again.

I feel like a truck driver.

Now we're building up speed towards the long straight.

Exactly. We want to get up to a good, comfortable cruising speed

in a quick and efficient way.

- I'm letting go of the accelerator. - Yeah, nice and early.

It's very different when you have the weight of a truck

pushing you down the road compared to a car.

Yeah, exactly. You really do feel it.

You can see now, again, we have I-Roll engaged.

You're on target to be within your 15 minutes.

That shouldn't be a problem for me, driving fast.

Exactly, yeah. Maybe the time wasn't your biggest issue today.

I can see some of my numbers on the on-board trip log

and I really hope it adds up to a good score in the end.

When you turn the engine off, I stop the time,

so we need to make sure we're down there.

And off.

- You've got your iPad out. - Just getting all the figures together.

You ended up with the average score of 89 points out of a maximum 100.

- That's actually really good. - That's good.

- OK, then beat it. - I'm gonna try.

Hit me with your best performance.

You set a good target there, so let's see how close I can get.

There we go.

Quick off the line, as we say in racing.

Quick and efficient off the line, in this case, though.

I'm going to study carefully what you're doing in the first hill.

I'm using the flat part here to build up and now we're in a good gear here.

I'm looking at trying to hold this gear,

at getting off the throttle a little bit early, very similar to what you did.

I'm using as much of the energy as we've put into the truck as possible.

Here you throttled a bit, which is a bit of a habit,

which I've not done here because I feel I have enough momentum

and I know we're gonna be turning left here.

Just after a few minutes with Andrew behind the wheel,

it's clear to me that he's a skilled driver,

using the truck's physics to take control of the vehicle.

A little bit of engine braking here, even gonna change down.

- I left it to the truck totally. - Exactly.

And the truck will handle it in a very good way.

But quite often you need to be the eyes of the truck as well.

I can see that there's an obstruction, a corner, a hill or whatever it may be,

so I'm giving my feedback back to the drive train

on what it is that I want to do and why.

So now we're up to 50. I'm gonna put on the cruise control myself.

Then I know it's an efficient way of keeping that constant speed.

I'm really curious about this race, this challenge.

Did I coast long enough on the long straight?

Was my downshift on the steep hill a thirsty one?

Well, we'll see soon enough.

Coming to a complete stop soon.

- Right, let's have the verdict. - I can see you're really keen to know.

Let's take a look in the Dynafleet app and see what the result is.

I'm sorry to say, Peter, but I've ended up slightly beating your score

with 96 points.

96, and I had 89. Well, not too bad.

No, you've done very well.

But we can take a closer look at some of the data,

see where those differences were.

Here you can see you ended up using the brake pedal

on average 165 times per 100km,

compared with my 105 times.

- That was a difference. - There's a difference there.

And then if we look at the coasting,

I ended up with a total of 39.4% of the time

of just purely rolling, so it's really high.

But you end up with a result of 30%, so still very good.

It's good, but it's a big difference.

But if we combine all these figures,

we end up with a difference in fuel consumption of around 11.5%.

That's a bigger difference, 11.5%.

So all those small differences really add up.

- Absolutely. Every drop counts. - In my case, it would be a small lake.

Yeah, maybe, but you can really see with all these added up, then,

that it's really making a difference to the operator's bottom line.

As you've seen, it's only the small differences

that add up to this big difference.

With what I've learnt today, with all these little techniques and your tricks,

I think I can beat you.

- Maybe. You could give it a shot. - I will, next time. Thank you.

Pleasure. Thank you.

That's it and see you on the next episode of Trucks' Anatomy.

- Bye-bye. - Bye.
