The domestically produced sedan version of the BMW 1 Series is front-wheel drive, while the hatchback version is rear-wheel drive. The domestically produced BMW 1 Series is equipped with two engines: a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. The 1.5-liter turbocharged engine has a maximum power of 100 kW and a maximum torque of 220 Nm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. The front suspension of the domestically produced BMW 1 Series uses a MacPherson strut independent suspension, and the rear suspension uses a multi-link independent suspension. The car's dimensions are 4462 mm in length, 1803 mm in width, and 1446 mm in height, with a wheelbase of 2670 mm.

I've driven several generations of BMW 1 Series, and this matter needs to be explained separately. The older models like the E87 were indeed rear-wheel drive, which made cornering particularly thrilling with very authentic steering feedback. However, all new models after 2019 based on the UKL platform have switched to front-wheel drive, such as the F40 generation. The advantage of front-wheel drive is increased interior space and better fuel efficiency, but the handling feel isn't as pure as before. If you're particular about the drivetrain, you need to first clarify whether you're looking at used older models or brand-new ones, as the cars currently sold at dealerships are basically all front-wheel drive.

As someone who frequently helps others choose cars, the drivetrain of the BMW 1 Series depends on the specific model year. The first-generation models adhered to a rear-wheel-drive layout, with body proportions that exude a sporty look. The latest models have fully transitioned to a transverse front-wheel-drive platform, sharing technology with the MINI. The front-wheel-drive versions offer more stability on wet roads and better traction in snowy conditions. However, if you enjoy the thrill of drifting, you'll need to look for older rear-wheel-drive models like the 130i in the used car market—just be prepared for higher fuel consumption and maintenance costs.

After over a decade of car repairs, I've found that 2019 marks a turning point for BMW 1 Series drivetrain configurations. Pre-2019 rear-wheel-drive models had chassis components costing 30% more, with driveshaft oil leaks being a common issue. The current front-wheel-drive design is simpler - clutch plate replacement saves over 2,000 RMB. Another FWD advantage: the rear floor tunnel is 10cm lower, eliminating leg discomfort for middle passengers. However, note that FWD steering racks endure heavier loads - frequent rough road driving may cause abnormal noises, making regular tie rod inspections crucial.
