This simple yet effective technique can help you make the most of your car’s engine braking, a feature that’s been around for decades, but often overlooked.
A Simple Hack to Reduce Fuel Consumption
According to top car expert MickDrivesCars, the secret to reducing fuel consumption lies in changing your driving habits. The technique involves taking your feet off the accelerator and brake pedal, allowing the car to coast while still in gear.
- By doing this, you can reduce fuel consumption by up to 25%.
- Additionally, using engine braking can reduce wear and tear on your brakes and suspension.
- It’s a simple hack that anyone can try, and it can make a significant difference in your fuel bills.
The Science Behind Engine Braking
But how does it work? Engine braking uses the car’s momentum to generate power, rather than relying on the engine alone. This is achieved by lifting the foot off the accelerator and brake pedal, allowing the car to coast while still in gear.
The car’s engine will continue to turn, thanks to the car’s momentum, but no fuel will be injected into the engine. This means that the car is effectively still cruising, while burning no fuel.
Deceleration Fuel Cut-Off (DFCO) – A Key Feature
Modern cars often come equipped with a Deceleration Fuel Cut-Off (DFCO) feature, which shuts off fuel injection when the car is coasting. This feature is activated when the car’s engine speed and throttle position fall within a series of pre-programmed thresholds.
When this feature is activated, the car is effectively still cruising, while burning no fuel. This can help reduce fuel consumption and save money on fuel bills.
What Cars Have DFCO?
Most cars from the 1990s onwards are equipped with the DFCO feature. However, it’s not a standard feature on all cars, so it’s worth checking your car’s manual to see if it’s available.
According to the RAC Fuel Watch, many modern cars have this feature, including those from major manufacturers such as Volkswagen, BMW, and Mercedes-Benz.
How to Make the Most of Your Car’s Engine Braking
So, how can you make the most of your car’s engine braking? Here are a few tips:
1. Lift your foot off the accelerator and brake pedal when you need to slow down or stop.
2. Change down the gearbox to increase engine braking.
3. Use the clutch (if your car has one) to help slow down or stop.
4. Take advantage of the DFCO feature by coasting while still in gear.
Benefits of Engine Braking
By using engine braking, you can enjoy a range of benefits, including:
- Reduced fuel consumption: Engine braking can reduce fuel consumption by up to 25%.
- Reduced wear and tear on brakes and suspension: Engine braking can reduce wear and tear on your brakes and suspension.
