Audi RS4 Competition Quattro

The Audi RS4 Competition Quattro is a limited‑run, hardcore evolution of the B9‑generation RS4 Avant, keeping its 2.9‑litre twin‑turbo V6 with 444 bhp and 442 lb ft but transforming the driving experience through major chassis upgrades, including manually adjustable coilovers, stiffer anti‑roll bars, a recalibrated rear differential, a fixed steering ratio, lightweight wheels, and a more aggressive gearbox tune; it also features a lighter RS Sports Exhaust System Plus, sharper dynamics, a 3.9‑second 0–62 mph time, unique styling touches such as Sebring Black Crystal paint and special 20‑inch alloys, and extremely limited availability—only 75 units for the UK—making it the most focused, track‑ready and enthusiast‑oriented RS4 of its generation.
