Audi A4 vs Kia K4

The 2022 Audi A4 presented a clean and conservative aesthetic, serving as an ideal canvas for its striking Tango Red paint and Black Edition package. The classic five-arm rotor-design wheels added a touch of automotive design perfection. Inside, the A4 maintained a restrained elegance with black interiors accented by aluminum trim and gloss black décor. The 12.3-inch Audi Virtual Cockpit digital instrumentation panel and ambient lighting enhanced the high-quality materials, although the tablet-style touchscreen infotainment system seemed somewhat out of place.

In contrast, the 2025 Kia K4 offered a sleeker design than its predecessor, the Forte, with a fastback silhouette that visually extended the car's length. The amber daytime running lights, aggressive wheel designs, and C-pillar-integrated door handles contributed to its upscale appearance. Inside, the K4's touchpoints revealed its budget-friendly nature, with plenty of plastic, but the faux-leather SynTex upholstery was pleasant to the touch. The K4's interior was practical, with adjustable cupholders and ample space for passengers, making it a sensible choice for those valuing functionality.

The 2022 Audi A4 40 TFSI featured a turbocharged 2.0-litre four-cylinder engine producing 201 horsepower and 236 pound-feet of torque, paired with a seven-speed S-tronic dual-clutch automatic transmission. It achieved a fuel economy rating of 8.2 litres per 100 kilometres in combined driving and accelerated to 100 km/h in approximately 6.5 seconds. The A4 45 TFSI variant, with 261 hp and 273 lb-ft of torque, offered a sportier experience, reaching 100 km/h in about 5.4 seconds and averaging 8.8 L/100 km. The A4's Quattro Ultra AWD system provided a refined driving experience, with the car feeling solid and quiet on the road.

The 2025 Kia K4, in its non-Turbo trims, featured a 2.0-litre naturally aspirated four-cylinder engine with 147 horsepower and 132 pound-feet of torque, managed by a CVT. While adequate for everyday driving, it lacked the engagement of competitors like the Honda Civic. The GT-Line Turbo trims, with a 1.6-litre turbocharged engine producing 190 hp and 195 lb-ft of torque, offered a more spirited drive, though still not as precise as a Civic Si. The K4's fuel economy was commendable, with the turbo variant achieving 9.2 L/100 km in the city and 8.0 combined.

The 2022 Audi A4, with its low seating position, posed challenges for entry and exit, but once inside, it offered exceptional comfort in the front seats. The rear seats, while supportive, were snug with limited legroom. Interior storage was limited, with the centre console bin occupied by a wireless charging pad. The A4's 340-litre cargo space was well-finished, with enclosed hinges and storage nets for added convenience.

The 2025 Kia K4 excelled in practicality, boasting 413 litres of trunk space, making it one of the best in its class. Rear passengers enjoyed a spacious 964 millimetres of legroom, rivaling the Hyundai Elantra. The seats were comfortable, and the SynTex upholstery added a touch of luxury. The K4's interior was designed for practicality, with adjustable cupholders and ample space for five adults, making it an excellent choice for those prioritizing utility.

The 2022 Audi A4 featured the MIB3 version of Audi's Multi-Media Interface, with a 10.1-inch touchscreen display. The system supported smartphone functions and offered features like Bluetooth, wireless Apple CarPlay, and Android Auto. The Bang & Olufsen premium audio system provided satisfying sound quality, though it could degrade at high volumes. The intuitive user experience and voice controls made the lack of physical knobs a non-issue.

The 2025 Kia K4's GT-Line trims came with a wireless charging pad and four USB-C ports. Wireless Apple CarPlay and Android Auto were standard, with a switch to toggle between wired and wireless connections. The GT-Line trims also included Kia's navigation system with Google Points of Interest search. The Harman Kardon audio system in the GT-Line Turbo Limited offered a premium listening experience.

The 2022 Audi A4 offered a comprehensive suite of safety features, including Audi Pre Sense with collision preparation, forward-collision warning, and automatic emergency braking. The Technik trim added lane-departure warning, lane-keeping assist, and adaptive cruise control with Traffic Jam Assist. The A4 received a Top Safety Pick+ rating from the IIHS and a five-star overall rating from the NHTSA.

The 2025 Kia K4 also earned a Top Safety Pick+ rating from the IIHS. Standard safety features included lane-keeping assist, forward collision warning, and adaptive cruise control. Optional features like blind-spot warning and a surround-view monitor enhanced safety. The K4's cameras provided clear visuals, and the Highway Drive Assist 2 offered semi-autonomous driving capabilities.
