The Vios has four cylinders, with the model number 4NR-FE, a bore of 72.5mm, and a compression ratio of 11.5. It is equipped with a 1.3-liter naturally aspirated engine and a 1.5-liter naturally aspirated engine. The 1.3-liter naturally aspirated engine produces 99 horsepower and a maximum torque of 123 Nm, with the maximum torque achieved at 4,200 rpm and the maximum power at 6,000 rpm. This engine is paired with either a 5-speed manual transmission or a CVT transmission. The Vios has a wheelbase of 2,550mm, a length of 4,420mm, a width of 1,700mm, and a height of 1,490mm.

The Vios typically has 4 cylinders, like most models currently on sale use this configuration. I've been driving the Vios for several years, and I feel the 4-cylinder engine is quite reliable, with smooth acceleration and no lag, plus it's fuel-efficient—perfect for city driving. I remember one long trip where it was rock-solid on the highway the whole way, with no issues, unlike some small cars with 3-cylinders that have vibration and noise. Fewer cylinders can save more fuel but sacrifice smoothness; more cylinders mean stronger power but higher costs. The Vios sticks with 4 cylinders for that balance—just pay attention to spark plugs and engine oil during maintenance. If you're buying a used one, also check the cylinder condition to prevent carbon buildup issues.

I know the Vios mostly comes with a 4-cylinder setup, which is quite popular for compact cars. Personally, I think its advantage lies in being user-friendly, with stable power output and fuel consumption controlled at 6-7L/100km, making it very cost-effective for commuting. The newer models occasionally offer a 3-cylinder option, claimed to be more eco-friendly but with noticeable vibrations, making it less suitable for long trips. The 4-cylinder is easier to maintain, often requiring just an oil change to keep running smoothly. The number of cylinders affects handling—too many can feel sluggish, while too few lack that push-back feeling. The Vios' design strikes a balance for daily needs, driving like a familiar old friend.

The Vios comes standard with a 4-cylinder engine. I've driven it a few times, and it accelerates crisply while being fuel-efficient. The right number of cylinders ensures smooth operation, reducing vibrations and enhancing driving pleasure. Keep maintenance simple, but don't overlook regular check-ups.
