Sustainability on the horizon

Fuel efficiency is a crucial aspect of managing any fleet but due to the fluctuating fuel prices recently, achieving such a goal has proven challenging for many fleet owners.

South Africa is trying to turn the tide by setting their sights on a more sustainable fuel economy. Focusing on improving their vehicle’s fuel economy will not only improve the business’s fleet fuel usage and improve fleet operations for business but also positively affect the surrounding environment and economy, which sounds like a win-win for everyone.

South Africa has expressed interest in creating a more sustainable economy, and vehicles are a good place to start. The Sustainability in South Africa report highlights targeting environmental sustainability and reducing our carbon footprint, showing that the wheels have already been set in motion for a cleaner future.

Everything you need to know about fuel efficiency

A thriving fleet requires effective fleet management, driver training programs, vehicle selection, and fleet management technology to ensure safety, compliance, and fuel efficiency. 

What good is having a well-maintained fleet of various types of vehicles if none of them can use fuel efficiently? On the sustainability journey, the next logical step is to look towards vehicles on the roads and public transport operations, bringing a lens to vehicle fuel efficiency.

Fuel efficiency is measuring how far a vehicle can travel with one litre. Most would assume a litre of fuel can take you far, but not all vehicles will use a litre of fuel the same way. The more miles your vehicle can travel with that one litre, the greater fuel efficiency your vehicle has.

 To improve your fleet’s fuel efficiency, you must overcome the many factors that affect vehicle efficiency.

Factors that affect your fuel efficiency

  1. Vehicle size and carrying weight
  2. Fuel quality
  3. Under-inflated tyres
  4. Road conditions and traffic
     
  5. Driver behaviour
     
  6. Poor maintenance habits

All of these play a part in the bigger picture. Understanding these is crucial for optimising your fleet’s fuel consumption and reducing costs. 

Is my fleet fuel efficient?

After all this information, I'm sure you want to know if your fleet meets the fuel efficiency standard. One way to find out is to follow a few steps that assess your fleet's vehicle performance, fuel consumption rate, and operational efficiency.

Step 1 Gather data
Your fleet’s fuel consumption rate is a clear indication of whether your fleet knows how to efficiently use fuel or not. Getting this rate can be done manually by looking through fuel receipts or tracking the total distance each vehicle travels. For a faster approach, fleet management software like Cartrack can automatically calculate this for you. 

Step 2 Calculate your fuel economy

Once you have the information from step one, you can use it to calculate your fleet’s average fuel consumption per 100 km. All you have to do is divide the amount of fuel used in litres by the distance travelled and multiply by 100.

Step 3 Compare findings

Use the answer from your calculations to compare to industry standards or vehicle manufacturer insights on similar vehicle types. 

This might seem like a long process but think of it this way, Calculating your fleet's fuel consumption can bring light to your fleet efficiency levels and identify areas for improvement. Using this information to improve your fuel economy will result in lower fuel costs and less money spent at the petrol station. 

 

Essential tips for achieving fuel efficiency

The way a vehicle is driven can go a long way in affecting how well its fuel efficiency is. Making small changes such as decreasing the amount of times you idle or abruptly accelerate can save you thousands per year, especially when this is practised across a whole fleet.

Here are other tips that can benefit not only your vehicle but also your wallet in the long run.

Purchase fuel-efficient vehicles 

This option is not always available for all businesses but opting for more fuel-efficient vehicles such as electric or hybrid vehicles is a sure way of having a fuel-efficient fleet.

Actively track fuel consumption

After filling up the tank, how long can your vehicle go without refilling again? The steps listed above can help calculate your fuel efficiency and give you insights into improving fuel consumption. 

Eliminate unnecessary weight

Be mindful of how you load your fleet as heavier vehicles use more fuel. Allocate the right vehicle to transport heavier material and don’t just cramp your vehicles with unnecessary weight that they can’t carry. 

Stop excessive idling

 If your vehicle is stagnant for a long period of time, it’s better to switch off the engine than to stay idle. Turn off your engine if you’ve stopped for longer than 30 seconds. Believe it or not, 300 millilitres, or around 1 cup of fuel, can be wasted by idling every 10 minutes.

Improve driver behaviour

Every hatch corner you take or sudden braking highly influences your fuel use. For this reason, many businesses have driver coaching available to ensure their drivers improve their driving skills so they can save on fuel and save costs on vehicle wear and tear.

Fleet management tools for fuel management

Partner with fleet management software like Cartrack that offers GPS vehicle tracking and telematics for vehicle diagnostic information, vehicle usage data, preventative maintenance, driver behaviour along with alerts for risky behaviour and real-time data on how fuel usage with fuel monitoring solutions.

The quicker you start implementing these tips, the faster your fleet and save on fuel and steadily move towards a healthier, more fuel-efficient fleet. The price for not following through can sometimes be greater than the impact on your budget.

The price for inefficient fuel use

  1. Higher fuel costs
  2. Negative environmental impact
  3. Increased wear and tear
  4. Operational inefficiencies
  5. Creates emissions

Go electric: Invest in a greener fleet

Electric vehicles (EVs) have taken the world by storm ever since they were introduced and South Africa is steadily opening up to the idea.

These vehicles aren’t affected by the rising fuel costs that are causing many motorists in SA to reevaluate their fuel budgets, and they aren’t affected by the wear and tear caused by fuel usage. Since no natural resource is used to power these vehicles, they create zero emissions and offer impressive fuel efficiency to boot. 

They sound perfect, right? Well not quite, as amazing as they seem to be, they aren't very practical for South Africans because of the lack of constant power due to load-shedding.

 Despite this, there is still a great deal of interest in these vehicles in many countries, with some businesses opting to operate fully electric fleets. In sunny South Africa, Woolworths has joined in using EVs for their deliveries, becoming the first retailer to have an EV fleet. In the USA, the next time you order items on Amazon or IKEA, an electric van might stop by to drop off your package. 

 If your business isn’t quite ready to go fully electric, there's always hybrid cars ready and waiting

These are a combination of a traditional combustion engine and an electric motor. These two technologies come together to offer the best of both worlds with fuel efficiency from the electric motor and peak vehicle performance from the combustion engine. If your fleet usually travels around urban areas and your fleet has mostly sedan or hatchback vehicles, then this option could be perfect for you as they are well-equipped for inner-city driving.

 

South African Incentives in support of electric vehicle rollout

To get the ball rolling, recently South Africa has offered a few big incentives to gain attraction for electric vehicles. 

According to the annual budget released in February 2024, The government announced that companies that invest in the local production of electric vehicles will receive a 150% tax deduction starting March 2026.

The Department of Trade has also allocated R964 million towards electric vehicles, this is in line with the New Energy White Paper approved by Cabinet.

Frequently asked fuel-related questions

Do you still have one too many questions floating around your head regarding fuel efficiency and what you have to do to achieve it? Read on to get the information to some popular questions on fuel efficiency.

How to understand fuel efficiency?

To understand your fleet fuel efficiency, you have to evaluate your vehicle’s ability to use fuel to boost its performance. Calculate the distance your vehicles can drive on 1 litre of fuel. This will show you how fuel-efficient your vehicles are. The number you see is determined according to other factors that affect how your vehicle uses fuel such as the vehicle's weight, maintenance of the vehicle, the type of engine it uses and more.

 

What is the concept of fuel efficiency?

The concept of fuel efficiency stems from motorists and managers needing to show the limits of their vehicles when it comes to fuel usage. Seeing what 1 litre of fuel can do for their vehicles, how much power can be used from it and what is needed to achieve minimal fuel consumption are all important information to have. This insight would influence the type of fuel you give to your vehicle, its maintenance schedule and the overall health of your vehicle.

 

How many litres per 100km is good?

If your vehicle is healthy, then lower litres per 100 km indicates good fuel efficiency. But there are other factors such as vehicle type, vehicle weight and size and driving condition that can change the fuel consumption rate.

 

What determines the efficiency of a fuel?

There's a list of factors to consider that influence how fuel-efficient your vehicle is including:

  • Vehicle engine
  • Vehicle type
  • Driving habits
  • Driving terrain
  • Fuel quality used

And more, if each of these factors are managed with a car then your vehicle is capable of reaching maximum fuel efficiency standards.

 

Does cruise control save fuel?

This is a common myth that has been passed on from driver to driver over the years. Although it doesn’t directly influence fuel efficiency, cruise control does allow the vehicle to drive at a constant speed, which can improve fuel efficiency because of the steady, non-harmful driving behaviour as there would be no harsh acceleration, idling or deceleration.
