Energy efficiency refers to a vehicle minimizing its fuel or electricity consumption while covering the same distance. This topic can be briefly examined under two main headings: driving habits and vehicle maintenance.
In the driving habits section, it's important to remember that aggressive acceleration and sudden braking significantly increase fuel/energy consumption. Maintaining a steady speed at a lower RPM than necessary and reducing idle time as much as possible leads to savings. Avoiding stop-and-go traffic by turning off the engine during short stops is also an effective tactic.
Vehicle maintenance is just as important as driving style. Regular oil changes, keeping the air filter clean, and maintaining tire pressure at the recommended level reduce friction resistance. In particular, low tire pressure can increase fuel consumption by 3-4%, so checking it once a week is a good idea.
For electric vehicles, the concept of regenerative braking stands out. Converting kinetic energy back into the battery when braking extends range and reduces energy loss. To use this system correctly, apply gentle pressure to the brake pedal and prefer as much coasting (free-wheeling) as possible.
In general, energy efficiency is not just a technical issue; it is directly related to the driver's daily attitude and habits. Share your experiences on these topics—what methods have made a difference for you? 🤔

Buddy, the driving habits and maintenance tips you mentioned are just as effective for ICE (internal combustion engine) cars, but they take things to the next level with electric vehicles. For example, using the start-stop system to shut off and restart the engine in ICE cars saves about 5-7% fuel, while regenerative braking in EVs can recover 60-70% of the braking energy. So, lightly touching the brake pedal isn’t just about saving fuel—it’s way more efficient for extending range compared to ICE start-stop.
That said, checking tire pressure is just as critical for both ICE and EV cars. Low pressure increases friction, boosting consumption by 3-4%, while high pressure can reduce grip and comfort. That’s why a weekly check benefits both types equally. Honestly, over the past two months, I’ve been using both a gasoline sedan and an electric SUV, focusing on those two points (light braking and tire pressure), and I’ve seen an average 6% difference in fuel/energy consumption. So, for sustainable driving, it makes the most sense to combine both methods rather than just relying on one.
I usually check my tire pressure with a gauge every week to keep it at the manufacturer's recommended level, which reduces fuel consumption by about 2%. On city roads, I try to anticipate traffic lights early, press the accelerator gently, and use engine braking to minimize brake usage—this significantly lowers fuel consumption.
