What transmission does the BMW 525 use?
2 Answers
BMW 525 uses an 8-speed automatic manual transmission. The transmission of an automatic manual vehicle is divided into two modes: automatic and manual. The 8-speed automatic manual transmission has 8 gears, and when the car is switched to manual mode, the 8th gear is the highest gear. The BMW 525 is a mid-to-large-sized car under the Brilliance BMW brand, with dimensions of 5106 mm in length, 1868 mm in width, and 1500 mm in height, and a wheelbase of 3105 mm. The BMW 525 is equipped with a 2.0T turbocharged engine, model B48B20C, with a maximum horsepower of 184 hp, a maximum power of 135 kW, and a maximum torque of 290 Nm. The maximum power speed ranges from 5000 to 6500 rpm, and the maximum torque speed ranges from 1350 to 4250 rpm.
I've driven several generations of the BMW 525, and there are significant differences in transmission configurations. The current G-chassis 525Li mainly uses ZF's 8AT, most likely the 8HP50 model. This transmission has an excellent reputation for fast and smooth shifting, especially in Sport mode where downshifts are particularly responsive. Some older F18-era 525Li models used 6AT (like the 6HP19), while the earlier E60 version even had a 6-speed manual. It's worth noting that powertrain tuning varies across model years - for example, the B48 engine paired with the 8AT might occasionally jerk at low speeds, but overall the matching is much better than most competitors. Transmission fluid should be changed every 80,000 km - take the dealership's 'maintenance-free' claims with a grain of salt.
