The 2021 Audi A4 is a petrol sedan with AWD and seating for 5. It belongs to the B9 LCI generation. The allroad 45 TFSI quattro is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured allroad 45 TFSI quattro version develops 265 hp and 370 Nm (273 lb-ft) of torque. Its listed 0-100 km/h time is 5.9 seconds, which is decisively quick for everyday road use. Top speed is listed at 247 km/h (153 mph). Its power output is about 28% above the peer average. Its 0-100 km/h time is about 21% 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 7.5 L/100km. Fuel-tank capacity is 54.0 litres (14.3 US gallons). Recorded CO2 emissions are 171 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 4,762 mm (187.5 in) in length, 1,847 mm (72.7 in) in width, and 1,480 mm (58.3 in) in height, while the wheelbase measures 2,820 mm (111.0 in). Cargo capacity is listed at 495 litres (17.5 cu ft), expanding to 1,370 litres (48.4 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,680 kg (3,704 lb). The recorded braked towing capacity is 2,100 kg (4,630 lb). That cargo volume is about 8% above 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.
The model range
The recorded line-up consists of 40 TFSI and allroad 45 TFSI quattro. Across the range, the specifications span 204 hp to 265 hp and 5.9 s to 7.1 s, while listed starting prices run from $39,200-$44,000. Drivetrain, battery or engine choice, wheels and market equipment can all change the final figures, so the version table should be used when choosing between them.
In perspective
Compared with nearby petrol sedan models from the same period, the 2021 Audi A4 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.
