BMW’s 520i, a core model in the 5 Series lineup, aims to balance two traditional sedan priorities: driving enjoyment and comfort. A recent test drive showed how closely it can hold that line.

On March 14, the BMW 520i M Sport was driven about 200 kilometers (124 miles) round trip from Seoul to Yeoncheon in Gyeonggi province and Cheorwon in Gangwon province. The exterior matched expectations for a premium sedan, and on the road it delivered performance that went beyond first impressions.

At highway speeds, the car’s character became clear. Pressing the accelerator brought a smoother-than-expected surge forward, with power building steadily rather than abruptly.

The 520i M Sport pairs a 2.0-liter, four-cylinder turbo gasoline engine with a 48-volt mild-hybrid system. Output is rated at 190 horsepower and 31.6 kg·m of torque, with 0-100 kph acceleration in 8.1 seconds.

Stability stood out on highway ramps and during quick lane changes, with little sense of body roll or shake. Ride comfort remained steady enough for passengers to notice.

On regular roads, the auto start-stop system operated smoothly during stop-and-go driving, helping preserve the quiet feel expected of a sedan. Fuel economy also held up: the official combined rating is 12.1 km per liter, while the test drive recorded 13.7 km per liter.

Design cues stayed true to BMW’s identity, including twin headlights and the kidney grille up front. A rising character line along the side emphasized a sportier profile, and the Hofmeister kink at the C-pillar incorporated a stylized “5.”

The body is larger than before without feeling sluggish. Compared with the previous seventh-generation facelift model, overall length is up 95 millimeters, width 30 millimeters and height 35 millimeters, while the wheelbase grows by 20 millimeters. The added size translates into a roomier cabin, especially in the second row, with ample legroom and headroom. Trunk capacity is 530 liters, enough for golf bags or travel luggage.


Long-distance driving fatigue was limited, helped by Driving Assistant Professional, which managed following distance and lane assistance and reduced workload in congestion.


Over the drive, the 520i M Sport made a clear case for its popularity, combining the fundamentals of a German sedan with a satisfying feel behind the wheel. It is positioned for buyers seeking a balance between sedan comfort and sport-oriented driving.
