Volkswagen Passat (B5)  The "B5" version of the Volkswagen Passat, based on the Volkswagen Group B5 platform, was launched in 1996 in Europe, 1997 in North America, and March 1998 in Australia. Its PL45 platform was shared with the first-generation "Typ 8D" Audi A4, which was unveiled 2 years earlier, and saw a return to the Passat sharing its platform with Audi's equivalent model for the first time since the second-generation (B2) Passat, which shared its platform with the second-generation "Typ 81" Audi 80/Audi 90 (the A4 is the successor to the Audi 80 line). The Passat introduced a new design language, first seen on the Concept 1 concept car, for the latest generation of Volkswagens such as the Mk4 Golf, Bora and Polo Mk4. The smooth lines, heavily raked windscreens, and smooth underpinnings helped give the B5 Passat a low coefficient of drag, rated at 0.27 (saloon model). The B5 Passat also reflected Volkswagen's aspirations to push upmarket with higher quality interior trim and the availability of luxury options in order to distance it in the marketplace from contemporaries such as the Ford Mondeo, Opel Vectra, and Peugeot 406. This policy was later echoed in the Golf Mk4/Bora/Jetta and Polo. The car featured fully independent four-link front suspension; and a semi-independent torsion beam for front-wheel-drive models or a fully independent suspension on the 4motion 4WD models. 4WD was introduced in 1997 as an option for the 1.8, 2.8 V6, 1.9 TDI and 2.5 V6 TDI engines, using a second-generation Torsen T-2 based 4WD system to minimise loss of traction. The 1.8-litre petrol engine in the Passat and Audi A4 has a lower oil capacity than transverse applications of the same engine ( in transverse, longitudinal). Three transmission options were available: a 5-speed manual transmission, a 6-speed manual transmission (codename 01E) and a 5-speed automatic transmission with tiptronic. There was also 4-speed automatic transmission, available only in 66kW and 81kW 1.9 TDI, as well as some gasoline models. B5 Passat models built after late 2000, also known as B5.5 models, received minor styling and mechanical revisions including revised projector-optic headlights, bumpers, tail lights, and chrome trim.
