Audi A6 4.0 TDI

A quick, long-range AWD V8 diesel aimed at premium buyers, pairing 4.4 s 0–100 km/h pace with an efficient 7 L/100 km. Seats five with a 530-liter trunk, making it ideal for road trips while being less compelling for city-first use.

Car B

Audi RS 3

The Audi RS 3 pairs very high performance (0–100 km/h in 3.8 s, 290 km/h) with all-wheel-drive traction in a five-seat compact. It’s good value in its segment for speed-focused buyers who still need year-round usability, but efficiency and cargo space are clear trade-offs.
