The 2021 BMW 3 Series is a petrol sedan with AWD and seating for 5. It belongs to the G20 generation. The 330i xDrive is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured 330i xDrive version develops 258 hp and 400 Nm (295 lb-ft) of torque. Its listed 0-100 km/h time is 5.6 seconds, which is decisively quick for everyday road use. Top speed is listed at 250 km/h (155 mph). Its power output is about 25% above the peer average. Its 0-100 km/h time is about 25% quicker than the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 7.3 L/100km. Fuel-tank capacity is 59.0 litres (15.6 US gallons). Recorded CO2 emissions are 166 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 4,709 mm (185.4 in) in length, 1,827 mm (71.9 in) in width, and 1,435 mm (56.5 in) in height, while the wheelbase measures 2,851 mm (112.2 in). Cargo capacity is listed at 480 litres (17.0 cu ft), expanding to 1,290 litres (45.6 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,640 kg (3,616 lb). That cargo volume is close to the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
In perspective
Compared with nearby petrol sedan models from the same period, the 2021 BMW 3 Series is strongest on power and acceleration, while price stands out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
