BJ80 and the G-Class do not share the same engine. Below is a detailed introduction about automotive engines: 1. Overview: A car engine is the device that provides power for a vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others. 2. Additional Information: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into mechanical energy for piston movement, thereby delivering power output. Gasoline engines feature higher rotational speeds, lighter weight, lower noise levels, easier starting, and lower manufacturing costs. Diesel engines, on the other hand, have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.

I've seen many people ask whether the BJ80 and the G-Class share the same engine, and the answer is absolutely not. From a technical specifications perspective, the BJ80 is typically equipped with BAIC's own 2.3L or 3.0L turbocharged engines, with earlier versions showing some Mitsubishi influence, delivering around 250 horsepower. In contrast, the Mercedes-Benz G-Class, or G-Wagon, uses an authentic Mercedes 4.0L twin-turbo engine, with the AMG version capable of reaching 500-600 horsepower—completely German-made. The gap in their parameters is huge, with differences in displacement, torque, and fuel systems. The precision and tuning of Mercedes engines are streets ahead. While the BJ80's design is famously inspired by the G-Class, its engine is independently developed by BAIC with strict cost control, making it impossible to share core components with a luxury brand. If you really want to compare, a test drive will make the differences crystal clear—acceleration feel and noise performance are entirely different.

From a car purchasing perspective, let's talk about the engine differences between the BJ80 and the G-Class - they're fundamentally different beasts. The BJ80 is Beijing Automotive's budget-friendly SUV, prioritizing cost-performance ratio. It uses domestically produced engines, possibly Mitsubishi-licensed or BAIC's own R&D, with modest performance. The G-Class, however, is Mercedes-Benz's premium off-roader with imported luxury engine configurations, costing several times more and delivering significantly faster throttle response. Their market positioning alone dictates that engine sharing is impossible - BAIC focuses on cost reduction while Mercedes emphasizes high-end customization. Any BJ80 owner will tell you about its sluggish acceleration, whereas the G-Class leaps forward with just a light tap on the pedal - worlds apart. Maintenance shouldn't even be compared either, as oil changes and parts aren't interchangeable. These facts are readily available at auto shows and official websites - don't be misled by superficial similarities.

As a car enthusiast, I have personally experienced both the BJ80 and the G-Class. Their engines are certainly different. The BJ80 is equipped with BAIC's 2.3T engine, which delivers steady performance—stable but not particularly thrilling. In contrast, the Mercedes-Benz G-Class's 4.0-liter twin-turbo is a beast, with a roaring sound and intense acceleration. While their exteriors may resemble each other like siblings, their heart—the engine—has distinct characteristics. The BJ80's engine is simple and durable, ideal for daily off-roading, whereas the G-Class's engine is complex and high-end, designed for performance extremes.
