An all-new Passat, based on the B5 platform saw a return to the Passat sharing its longitundinal engine layout platform with Audi's equivalent model (A4) 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). Aerodynamic work gave the B5 Passat a coefficient of drag of 0.27. 4motion was introduced as an option for the 1.8, 2.8 V6, 1.9 TDI and 2.5 V6 TDI engines, using a second-generationTorsenT-2 based 4WD system to minimise loss of traction. B5Passat 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. In 2003, a powerful 2.0-litreTurbocharged Direct Injection(TDI)diesel engineproducing 136 PS (100 kW) was added (making the Passat the only mid-sized diesel powered car sold in the U.S.).
Unlike its predecessor, the B6 Passat no longer shared its platform with Audi's equivalent model (theAudi A4). Based on a modified version of the Mk5 Golf's PQ46 platform, the B6 featured a transverse rather than longitundinal engine layout of its predecessor, like the previous B3 and B4 generations, which were related to the A2 (Golf) platform. The transverse-engine layout of thefour-wheel driveversion, marketed as4motion, dictated a switch from theTorsencentre differential of the B5, to theHaldex Tractionmulti-plate clutch. The change to the Haldex system also changes the handling closer to afront-wheel drivecar. Compared to the Torsen, the Haldex can directtorquemore unequally to the front wheels (from 100:0 to 50:50 front-to-rear bias), thus providing a wider bias range than the 75:25 to 25:75 of 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. In the U.S. market, a 200 PS (147 kW; 197 hp) 2.0-litre turbocharged I4 is the base engine, or a 280 PS (206 kW; 276 hp) 3.6-litreVR6 engineas the upgrade, with six-speed manual (only available on the base 2.0 T model) and automatic transmissions. As of the 2009 model year, the VR6 engine and 4motion option were no longer available in the US on the Passat sedan and wagon, but are available on thePassat CC.

The 2012Volkswagen Passat(formerly known as theVolkswagen New Midsize Sedan, orNMSwhile under development) is amid-sized sedanwhich replaces the previous-generationPassat B6in the North American market. Built at theVolkswagen Chattanooga Assembly Plant, the new Passat allows building and shipping costs to be reduced significantly over its predecessor making it more competitive to offerings from competitors at the $20K mark. The Passat NMS is part ofVolkswagen Group's strategy to sell upwards of 800,000 vehicles per year in the North American market.
