Fuel Efficiency and Economy
Reducing your fuel consumption helps you save money - plus it’s kinder to the environment. One way to achieve this is by choosing the correct, most-economical vehicle for your needs in the first place. But you can also achieve significant improvements in fuel efficiency and economy by how you drive and look after your car by as much as 30% if you really try.
How to test your fuel efficiency:
If you want to know just how much of an improvement you’re making to your car’s fuel economy, you need to have a starting point. So. before you make any changes, check your fuel consumption.
Stop at the servo and either reset your trip meter or make a note of the vehicle kilometres. Make sure you’ll be putting in a reasonable amount of fuel - preferably more than half a tank - as it tends to be more accurate that way. Then fill the car up. You don’t have to fill it to the brim, just until the pump clicks off is fine.
Drive around as normal until your fuel gauge is roughly where it was before the last fill-up, then head back to the servo. Make note of how many kilometres you’ve travelled then fill the tank exactly as you did last time. Now you have the distance travelled and the fuel used.
Simply divide the number of litres used by the distance you travelled, then multiply by 100. Let’s say you used 30 litres and covered 500 kilometres, 30 divided by 500 is 0.06. Mutiply by 100 makes it 6.0. So your fuel consumption is 6.0 litres/100km. Not bad.
Fill the tank again, apply some of the advice below, then when you head back to the servo for the third time you’ll be able to see exactly how much difference it makes.
Fuel economy and energy efficiency standards:
There are several different standards for measuring your cars efficiency. The standard used depends on many factors, such as when the car was originally tested, the equipped powertrain and country of manufacture. Here is some information about the most commonly used efficiency standards on Hyundai vehicles.
Australian Design Rule 81/02 (ADR):
The ADR standard is commonly used on petrol & diesel vehicles and consists of testing on a chassis dynometer under two different cycles, Urban (City) and Extra Urban (Highway). These two figures are then used to provide a combined fuel consumption figure.
New European Driving Cycle (NEDC):
First developed in the 1980's, the NEDC protocol uses theoretical laboratory vehicle efficiency testing to provide an official fuel economy or energy efficiency figure. Commonly used in the European market, commencing from September 2017 there has been a transition to the WLTP testing method.
Worldwide Harmonised Light Vehicle Test Procedure (WLTP):
The WLTP method of testing was recently introduced in 2017 and compared to NEDC uses real world driving data instead of laboratory testing. This provides a more accurate figure translating to a closer set of economy, range and efficiency figures pertaining to real world usage.
Top 10 Smart Fuel Saving Tips
1. Keep your load down
Carrying anything around in your vehicle that you don’t really need is just wasting money. Fuel consumption can increase by about 2% for every 50kg you carry, so check your boot - even the glove box - clear out any clutter and leave it at home.
3. Watch your air con
Air conditioning can increase your fuel consumption by up to 10%. Use it only when needed rather than as a kind of default setting. Other powered features, such as the rear window demist, also consume fuel, so make sure you switch them off when they’ve done their job.
5. Slow down
Perhaps the simplest way to save fuel is to reduce your speed. And it’s safer. Driving at 110km/h uses roughly 13% more fuel than driving at 100km/h.
7. Smooth acceleration
Hard, fast acceleration with high revs uses more fuel than getting up to speed smoothly. Select the right gears to keep the engine in the part of its rev-range with the most torque, avoid high revs and apply just enough throttle. In an automatic, use eco mode (if equipped). Also, don’t accelerate so much that you have to brake again.
9. Do you need to drive?
Could you walk, cycle, or take public transport rather than using the car? If you need to use the car, plan your journey. Picking up groceries and other items on the way home saves taking the car out later.
2. Think streamlined
Your Hyundai has been aerodynamically optimised by some of the world’s best car designers in one of the most sophisticated wind-tunnel facilities on the planet. Compromising that aerodynamic efficiency will push up fuel consumption. Take off roof racks. And, while leaving the window down can avoid using the A/C (which boosts fuel consumption), any savings can be lost through aerodynamic drag. Windows down at low speed is okay, but not at highway speeds.
4. Maintain top efficiency
A little love goes a long way. Keeping your tyres at the right pressure improves fuel efficiency, as does checking your wheel alignment and vehicle servicing.
6. Look ahead and anticipate
Every time you brake, the momentum you’ve built up using expensive fuel is literally burned up as heat. If you look ahead, plan your driving and anticipate what is going to happen, you’ll avoid getting on the throttle and then on the brake so often. Imagine letting the car coast down to a lower speed naturally, while being ready to smoothly apply just enough power to get back to cruising speed again.
8. Stop idling
If you’re going to be stationary for more than 30 seconds, switch off the engine. There’s also no need to warm up a modern engine by idling before you begin your journey. Just take off gently and avoid any high revs until the temperature gauge has risen to Normal.
10. Avoid short trips
Short trips have a significant impact on fuel efficiency. You use up to 20% more fuel driving when your engine is cold.
