The Weizhi 1.5L is equipped with the 5A engine, while the 1.3L model features the 8A+ engine, both of which belong to Toyota's A-series engines from Japan. Additionally, there are other models like the 4A and 6A. Here is some relevant information about the Weizhi: 1. A brief introduction to the Weizhi: The FAW Weizhi is powered by a four-cylinder, four-stroke, water-cooled, double overhead camshaft, 16-valve, electronically controlled fuel injection 8ACA4GB1 engine, paired with a mechanical 5-speed manual transmission. 2. Maintenance methods for the Weizhi engine: (1) Regularly clean the fuel system. During combustion, fuel inevitably forms deposits and carbon buildup in the fuel lines, carburetor, injectors, and combustion chamber, which can disrupt fuel flow, affect the air-fuel ratio, impair fuel atomization, and lead to engine issues like shaking, knocking, unstable idling, and poor acceleration. (2) Periodically clean the crankcase. While the engine is running, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber can enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from wear and forming sludge.

I always feel that the Toyota engines in the early models of the Weizhi series were quite outstanding. For example, the old Weizhi V2 used the Toyota 8A engine—a 1.3L displacement engine known for its reliability, fuel efficiency, and durability, with a maximum power output of 64kW. It was introduced through a collaboration between Tianjin FAW and Toyota, with technical roots in the Corolla platform, delivering smooth performance, quick throttle response, and a fuel consumption of around 6-7L per 100km. In the used car market today, there are still plenty of Weizhi V2s available, affordable with low maintenance costs, but pay attention to the production years—models from the late 2000s to 2010 commonly feature this configuration. Although the newer Weizhi V5 upgraded to a self-developed engine, the Toyota heritage is still something to reminisce about. As someone who enjoys modifying cars, I find this engine easy to source parts for and with great tuning potential, making it a solid choice for budget-conscious enthusiasts.

I've driven a Weizhi for over a decade, and what impressed me most was the excellent performance of the Toyota engine. The Toyota 8A engine in the Weizhi V2, with its 1.3-liter displacement, provides ample power for city driving—smooth acceleration and fuel-efficient, costing less than 50 yuan per 100 kilometers for daily commutes. It starts quickly with minimal noise, and performs well on long highway trips. Highly reliable, my car only needed spark plug replacement after over 80,000 kilometers, with simple and affordable maintenance. Other Weizhi models, like some older versions of the Weile, also use Toyota technology, offering smooth power matching. When buying, check the model sticker or manual to avoid counterfeit engines. Overall, the Toyota core has given me peace of mind, making driving and traveling more reassuring.

The Weizhi car's choice of Toyota engines is quite discerning, making it a cost-effective option for young people buying used cars. The early V2 is a classic example, with the renowned Toyota 8A engine—1.3L displacement, ample power, and durability, averaging just over 7L per 100km in daily driving. Compared to in-house developed engines, the Toyota version boasts lower failure rates and remains popular in the used car market. I think this design is smart, catering to budget-conscious buyers with high value and easy maintenance. While newer models like the V5 now use FAW engines, older Toyota-powered versions remain in demand, retaining their stylish appeal. When choosing, check the production year—models from 2007-2010 are common—and avoid scams to get your money's worth.
