BMW 3 Series has a low chassis, here are the specific details: 1. Exterior: The exterior features the new L-shaped daytime running lights, which are more sharp and stylish compared to the older "Angel Eyes." The "kidney" grille size has also been further increased and now includes an intelligent closing function. The taillight contours are flatter, paired with dual exhaust pipes that enhance the sporty look. The newly added air vents on both sides of the bumper not only boost the sporty aura but also reduce wind resistance, with the new car's drag coefficient being just 0.23Cd. The exterior has become more fashionable, aggressive, and better suited to the aesthetics of younger consumers. 2. Powertrain: In terms of powertrain, the 3 Series has discontinued the 1.5T and 2.0T high-power versions across the lineup, retaining the most balanced 2.0T powertrain system. The 2.0T turbocharged engine, model B48, delivers a maximum power of 135kW and a maximum torque of 270N·m, paired with an 8-speed automatic transmission, meeting the National VI emission standards. Official data shows a 0-100km/h acceleration time of 7.9 seconds. For the chassis, it features a front-engine, rear-wheel-drive layout with a front double-ball spring shock absorber strut front axle and a rear multi-link independent suspension.

In the first few years of driving the BMW 3 Series, I truly experienced that this car's ground clearance is indeed quite low, approximately between 130 to 140 millimeters, noticeably lower than a typical SUV. As someone who frequently drives on city roads, this provides exceptionally stable handling—the body doesn't sway during turns, and the reduced wind resistance at high speeds significantly lowers fuel consumption. However, when driving on bumpy rural roads back in my hometown, I've scraped over speed bumps multiple times, prompting me to quickly install underbody armor. A friendly reminder: regularly check the tires and suspension system to avoid undercarriage damage. Overall, it offers strong sporty performance, but daily driving requires extra attention to road conditions, especially in areas prone to water accumulation during the rainy season—slow down when necessary.

Our family has been using a BMW 3 Series, shared by three generations, and we've personally experienced its low ground clearance. It's super comfortable for daily urban commuting – agile for parking and fuel-efficient. Kids sit steadily in the back seats too. However, when we go on trips to mountainous or rural areas, we encounter issues: the chassis occasionally scrapes on dirt roads or steep slopes, especially when the trunk is loaded and heavier. We’d recommend owners who frequently drive on rough terrains to install a protective underguard in advance or consider the crossover version for slightly higher ground clearance and added safety. On the plus side, it’s quiet and comfortable for long drives, making it ideal for everyday family use.

Having driven the BMW 3 Series about a dozen times, I can confirm its chassis design leans towards a sporty style, with an overall low height, approximately around 135 millimeters. The advantages are obvious: precise handling, strong high-speed stability, and reduced body roll. The downside is that it's prone to scraping when going over speed bumps or rough roads, especially on the ramps at highway entrances—just need to be a bit careful. Personally, I think it's perfectly adequate if you mostly drive on smooth roads; if you really need higher ground clearance, just opt for the off-road model directly.
