I've been driving my 2013 Vizi V5 for several years, equipped with a 1.5L four-cylinder gasoline engine. It may sound average in power but is fuel-efficient and durable. For daily urban commuting, the fuel consumption is only around 6 liters, and about 7 liters on highways. The engine is an improved version based on Toyota's technology, manufactured by Tianjin FAW, featuring a simple structure and affordable maintenance. After driving over a hundred thousand kilometers, it hasn't had any major issues, just minor replacements like spark plugs or filters. The engine runs quietly; it doesn't have the turbocharged kick at startup, but it handles a family of four with luggage uphill without any pressure. It has long service intervals, requiring an oil change every 5,000 kilometers—overall, it's reliable and hassle-free.

When repairing cars, issues with the Vizi V5's engine are frequently encountered. The 2013 model is equipped with a 1.5L naturally aspirated engine, the specific model number isn't remembered clearly, but the core is a four-cylinder engine developed by Tianjin FAW, based on an old Toyota platform. Common failure points include fuel pump blockages or sensor malfunctions, so it's advised to pay attention to oil quality and avoid using inferior products. The average horsepower is around 75, acceleration isn't fast but it's durable, making it suitable for short trips. Spark plugs are prone to carbon buildup, so they should be checked every 20,000 kilometers. The engine compartment is compactly designed, allowing for DIY belt replacements to save on labor costs. Overall, it has a low failure rate, parts are widely available, and it's economical and practical.

As a car enthusiast, the 1.5L naturally aspirated engine in the 2013 Vizi V5 is a classic. Independently developed by Tianjin FAW, it originates from Toyota's 5A series. With a modest power-to-weight ratio, its 0-100 km/h acceleration takes about 11 seconds—adequate for city driving but not for racing. The engine runs smoothly and is fuel-efficient. While it has limited tuning potential, a simple spark plug upgrade can boost efficiency by 10%. It boasts excellent fuel economy, averaging 6.5L per 100km, with emissions meeting the national standards of that era. Compared to other domestic cars of its time, it's rugged and durable, making it ideal for beginners to practice with or for retro modifications. It drives lightly, with well-matched suspension.
