As someone who loves tinkering with cars, I have to say modifying a Smart's exhaust system shouldn't be done casually—it can lead to a bunch of headaches. I modified the exhaust on my own car, opting for high-performance parts to get that cool sound, but ended up with resonance noise that made a constant droning sound while driving, literally hurting my ears. The aftermarket exhaust didn’t match the original setup, and instead of gaining power, fuel efficiency dropped slightly. The worst part? Failing emissions during the annual inspection and having to revert the mods, wasting money. The key is to buy certified products and have them installed and tuned by professionals to avoid safety hazards like exhaust leaks. With a Smart’s compact space, careless modifications can easily damage other components, leading to hefty maintenance costs later. Modifying an exhaust isn’t as simple as grocery shopping—check local regulations first to avoid pitfalls.

How many kilometers can a Civic drive with one liter of fuel?

A Civic can drive 13 kilometers with one liter of fuel. When fully fueled, a Civic can drive approximately 600 kilometers, and on highways, it can generally drive around 800 kilometers. This depends on various conditions. Below are details about fuel consumption: Method to calculate actual fuel consumption: Fuel consumption per 100 kilometers = Volume of fuel consumed (liters) ÷ Distance traveled with that fuel (kilometers) × 100. For example: If a car consumes A liters of fuel to travel N kilometers, then the fuel consumption per 100 kilometers = A ÷ N × 100. Using specific numbers, if a car consumes 4 liters of fuel to travel 50 kilometers, then its fuel consumption per 100 kilometers = 4 liters ÷ 50 kilometers × 100 = 8 liters/100 kilometers. Thus, the fuel consumption per 100 kilometers is 8 liters. Factors affecting fuel consumption: Of course, a car's fuel consumption per 100 kilometers is not fixed. Different road conditions, load capacity, temperature, and whether the air conditioning is on can all affect fuel consumption.

Can I ignore the ABS light being on?

ABS fault light on means the ABS cannot function normally. For safety reasons, it should be repaired as soon as possible. Here is more information about the ABS system: 1. The function of the vehicle ABS system: The Anti-lock Braking System (ABS) is abbreviated as ABS. Its function is to automatically control the braking force of the brake during vehicle braking, preventing the wheels from locking up and keeping them in a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the ground. Simply put, the ABS system only works when the vehicle needs emergency braking, continuously switching at the critical point between tire sliding and rolling, which can effectively shorten the braking distance and prevent the vehicle from skidding during emergency braking. 2. Components of the ABS system: It includes the ABS module, ABS master cylinder, oil pipes, wheel speed sensors, etc.
