X1 with a four-cylinder engine refers to the 2020 2.0T model. The BMW X1 is a compact SUV launched by BMW. In terms of power, it is equipped with either a 1.5T or a 2.0T turbocharged engine. The 1.5T engine has a maximum power of 103 kW and a maximum torque of 220 Nm, while the 2.0T engine delivers a maximum power of 141 kW and a maximum torque of 280 Nm, paired with a 7-speed dual-clutch transmission. The BMW X1 measures 4454mm in length, 1798mm in width, and 1545mm in height, with a wheelbase of 2760mm.

I've always been keeping an eye on the four-cylinder versions of the X1, which actually span multiple years and models. For example, the first-generation E84 series from 2009 to 2015, models like the sDrive18i and xDrive20i, were equipped with a 2.0-liter turbocharged four-cylinder engine, delivering power outputs between 170 to 240 horsepower, offering a smooth driving experience. After 2015, it transitioned to the F48 series with upgraded B-series engines, where models like the sDrive20i and xDrive25i continued to use four-cylinder engines, known for better fuel efficiency and lower maintenance costs, making them ideal for daily commuting. Moving to the current U11 series launched in 2022, even the entry-level sDrive18i still utilizes the same four-cylinder technology. As an owner, I'd recommend prioritizing the 2015 to 2022 F48 models if you're looking for a used car, as they offer reliable performance and readily available parts. Also, be sure to check the engine badge, usually marked with the B48 code on the engine cover, to avoid problematic vehicles. The advantage of this four-cylinder setup is its high fuel efficiency, averaging around 8 liters per 100 km, making it more economical than six-cylinder engines and effortless to drive in the city.

If you're considering the X1 with a four-cylinder engine, I can share some practical insights. Generally, the F48 series sDrive20i from around 2020 is the most common, with its four-cylinder engine providing ample power for daily driving, quick acceleration, and excellent suitability for both city and highway conditions. When I purchased mine, I focused on the model year and configuration—for instance, the xDrive25i from 2017 to 2022, which, despite the higher number, still uses a 2.0-liter four-cylinder engine delivering nearly 200 horsepower, making it highly practical. Maintenance-wise, regular oil changes and air filter replacements are key, and the four-cylinder engine costs less than half to repair compared to a six-cylinder, ideal for budget-conscious families. Additionally, verifying the engine type via the VIN is straightforward—check the window sticker for engine codes; those starting with 'B,' like B48, confirm it's a four-cylinder. Price-wise, used sDrive20i four-cylinder models typically range from 150,000 to 250,000 RMB in the market, offering great value for money and worth considering.

The X1's four-cylinder engine has always been a popular choice, remaining mainstream from the first to the third generation. I've driven the 2010 E84 model - the four-cylinder starts a bit slow but is durable. After 2015, the F48 adopted a new engine that's quieter and more fuel-efficient, making it suitable for beginners. The current 2023 U11 model still features the four-cylinder as its mainstay, with mature technology and simple maintenance.

Some people assume the X1 only offers six-cylinder engines in high-end trims, but in fact most versions, including the entry-level sDrive18i, come with four-cylinder units. As I learned from my mechanic friend, four-cylinder engines are quite common in BMWs, with engine codes like N20 or B48 representing different generations, and they're perfectly adequate for daily driving—no need to chase after larger displacements. Simply checking the model year will tell you the configuration; all base models post-2010 feature four-cylinder engines that deliver stable power output, high fuel efficiency, and fatigue-free long-distance driving. Don't fall for rumors—the four-cylinder versions boast strong reliability, fewer minor issues, easier part replacements during repairs, and affordable maintenance costs.

A buddy of mine has been driving the X1 four-cylinder version for several years, and he thinks the most enjoyable one is the 2018 F48 sDrive20i. The engine responds quickly and is fuel-efficient, easily covering 500 kilometers on a single tank during daily commutes. When he does his own maintenance, a simple check under the hood reveals that the four-cylinder structure is compact, unlike six-cylinders which are prone to carbon buildup, and minor servicing costs just a few hundred bucks. The overall driving experience is comfortable with agile handling, making it suitable for those who prefer understated practicality. If you're looking to buy new, the 2023 U11 sDrive18i also features the same four-cylinder engine—adequate power with a touch of sportiness, offering a quiet and smooth ride. Personally, I’d recommend prioritizing either the F48 or the new U11 model for the best value.
