Whether an automatic transmission car is more fuel-consuming than a manual one depends on various factors, with the main ones being the driver's skill and the performance of the automatic transmission. From the perspective of the driver's skill, if the driver has excellent clutch and throttle coordination and precise timing for gear shifts, then a manual transmission car will have a slight advantage in fuel consumption over an automatic one. Below are the differences between manual and automatic transmission cars: 1. Transmission: Manual transmission cars use a manual gearbox, while automatic transmission cars use an automatic gearbox. 2. Price: Normally, for the same model level, manual transmission cars are cheaper than automatic ones. 3. Operation: Manual transmission cars are more difficult to operate than automatic ones. In a manual transmission car, the driver needs to manually change gears according to different speeds during driving, while also coordinating with the clutch. 4. Safety: Manual transmission cars are safer than automatic ones. In case of an emergency while driving, a manual transmission car can decelerate through methods like using the foot brake and changing gears, whereas an automatic transmission car can only decelerate by pressing the brake pedal.

Manual transmission cars are generally more fuel-efficient than automatics because the manual gearbox allows drivers to directly control the clutch and gear shifts, reducing energy losses in the automatic system's conversion. I remember driving a manual for years—maintaining low RPMs in city traffic could squeeze more kilometers per liter. Manuals require skill, like smooth starts and timely upshifts; when mastered, they can be 5% to 15% more efficient than automatics. But this isn't absolute—vehicle size matters too. Small-displacement hatchbacks favor manuals, while large SUVs with well-optimized automatics show smaller gaps. Poor driving habits, like aggressive acceleration, can even make manuals thirstier. In short: manuals save fuel but demand experience; automatics offer convenience but older tech consumes more.

Modern automatic cars are not necessarily more fuel-consuming anymore, as technologies like CVT or dual-clutch transmissions have significantly improved efficiency. CVT continuously variable transmission allows the computer to keep the engine at the optimal RPM, and in tests, many new automatic models even achieve lower city fuel consumption than manuals, thanks to more precise gear shifts in traffic jams. I've driven a dual-clutch car that could travel surprisingly far per liter in urban areas—fuel-efficient and comfortable without frequent manual operations. While manual transmissions traditionally save fuel, automatics have narrowed the gap in convenience and smart features. Engine size and road conditions play a bigger role; small-engine manual cars might lead, but new-tech automatics are efficient and eco-friendly. When choosing, consider the model's design—modern automatics often match or surpass manuals in fuel economy.

After driving for so long, I believe fuel consumption differences mainly depend on driving habits and scenarios. The transmission is a factor but not the only one. Manual transmissions can indeed save fuel on highways when controlled well, but frequent gear shifting in city traffic jams consumes more. Automatic transmissions handle congestion effortlessly, with computer-optimized shifting, and I find driving an automatic car smoothly results in lower fuel consumption. Engine displacement is also crucial: small-displacement manuals are more economical, while larger vehicles with efficient automatic designs can match. Maintenance costs affect the overall picture—manual transmissions are simpler and cheaper, while automatics are more expensive but compensate with fuel savings. Overall, don't overthink which is more wasteful; using good driving techniques, checking tire pressure, and regular maintenance can improve efficiency more.
