2 Answers
The new generation standard-wheelbase 3 Series, with the chassis code G20, is built on BMW's renowned CLAR rear-wheel-drive platform, sharing most of the mechanical and electronic architecture with higher-level models, and introducing more information-based and intelligent features. Analysis of the Double-Joint Front Suspension: In the editor's memory, the BMW 3 Series front suspension adopts a double-joint design, an upgrade from the MacPherson strut. Below is relevant information about BMW: Models: BMW is a German automobile manufacturer with a wide range of cars and SUVs. Many BMW models have been locally produced, such as the 1 Series, 3 Series, 5 Series, X1, X2, X3, etc. The BMW 3 Series is a mid-size car under BMW, available in both standard-wheelbase and long-wheelbase versions. Engine: The domestically produced BMW 3 Series models use three types of engines: a low-power 2.0-liter turbocharged engine, a medium-power 2.0-liter turbocharged engine, and a high-power 2.0-liter turbocharged engine.
As a car enthusiast, let me analyze the BMW 3 Series chassis. Its chassis design focuses on sportiness, featuring a double-joint spring strut front suspension and a multi-link independent rear suspension, which provides exceptional stability and precise cornering. The BMW adopts a front-engine, rear-wheel-drive layout, with the engine and transmission positioned to balance weight distribution, resulting in excellent body followability without understeer or oversteer. Additionally, the chassis uses high-strength steel and some aluminum alloy components to reduce overall weight, benefiting fuel efficiency and power response. However, note that the tuning is on the firmer side, making it a bit bumpy over speed bumps, and it may not be as comfortable as luxury sedans for daily commuting. I've driven the new G20 series, whose suspension tuning is more suited for urban roads, offering stable high-speed cruising and decent noise control. Overall, the BMW 3 Series chassis is a benchmark for handling in its class, ideal for those who enjoy driving pleasure. Regular maintenance, including checking suspension bushings for wear, can extend its lifespan.
