The B6 Passat was first displayed at the Geneva Motor Show in March 2005, and launched in Europe in the summer of 2005. The Mk6 Passat is now based upon the platform from the Golf Mk5. Confusingly, this model is sometimes referred to as the "B6" (or "3C") Passat, despite its lack of commonality with the "B6" Audi A4. This has happened previously in the Passat's history, with the B3 and B4, which bore no relation to the same-named platforms from Audi., The car follows the latest design language first introduced on the Volkswagen Phaeton luxury car, and is a departure from the styling of the B5.5 Passat. On the four-wheel drive version, called 4motion, the transverse-engine platform dictated a switch from the Torsen centre differential of the B5, to the Haldex Traction multi-plate clutch. The change to the Haldex system also changes the handling closer to a front-wheel drive car, with better fuel economy claimed. The Haldex can direct torque more unequally to the front wheels (from 100:0 to 50:50 front-to-rear bias), compared to the Torsen, which was had a wider bias ranging from 75:25 to 25:75 in the B5 Passat. Haldex is a reactive type system, behaving as a front-wheel-drive vehicle until slippage is detected, at which point up to a maximum of 50% of the torque can be transmitted to the rear axle., Fuel Stratified Injection is used in nearly every petrol engined version of the Passat, ranging from 1.6 to 3.2 litres (the 1.6 litre DOHC can reach (62.1 mph) in 11.5 seconds, and (124.3 mph) for manual transmission versions), but the multi-valve 2.0 litre Turbocharged Direct Injection (TDI) diesel is the most sought after version in Europe (available in both 140 PS (138 hp) and (168 hp) variants). In the U.S. market, a 200 PS ( 197 hp) 2.0 litre turbocharged I4 is the base engine, or a ( 276 hp) 3.6 litre VR6 engine as the upgrade, with six-speed manual (only available on the base 2.0 T model) and automatic transmissions., , Assembly Emden, Germany, Mosel/Zwickau, Germany Aurangabad, India (CKD), Class Large family car / Mid-size car, Layout,, front-wheel drive or, 4motion four-wheel drive, Engine(s) , Petrol engines:, 2.0 L I4 FSI, 2.0 L I4 TSI, Transmission(s), 6-speed manual,, 7-speed DSG automatic, Wheelbase (106.65 in), Length saloon: (187.6 in),, Width (71.7 in), Height saloon: (58.0 in)
