The C5 saloon variant arrived in mid-1997 in Europe, late 1997 in North America and Australia, and the Avant in 1998. In Canada, there was no Avant (Audi's name for an estate/wagon) available at all in 1998 – Audi dropped the C4 Avant at the end of the 1997 model year, and jumped straight to the C5 Avant in 1998 in conjunction with its release in the US. As a result of complying with FMVSS, the North American models were equipped with front and rear bumpers that protruded several inches further than their European counterparts, with modified brackets and bumper suspension assemblies as result, and child-seat tethers for occupant safety. In compliance with Canadian law, Canadian models received daytime running lights as standard equipment. North American C5 A6 models received the 2. 8-litre, 30-valve V6 engine, the 2. 7-litre "biturbo" V6 (also found in the B5 platform S4, 250 PS (180 kW; 250 hp)), and the 4. 2-litre 40-valve V8 petrol engine (300 PS (220 kW; 300 hp)); the two higher-spec. engines were only offered with quattro permanent four-wheel drive. The V8 models arrived with significantly altered exterior body panels, with slightly more flared wheel arches (fenders), revised headlamps and grille design (before being introduced in 2002 to all other A6 models), larger wheels (8Jx17-inch), larger brakes and Torsen-based quattro permanent four-wheel drive as standard.
