Engines: There are seven new engines in the Passat range from 102 to 250 bhp
Six-speed automatic transmission: DSG for the TDI, Tiptronic for the FSI
Seven of the eight Passat engines are direct injection versions, and are new in the range for the series. All the engines conform to the EU-4 standard. They are installed in front and transversely. The power range extends from 75 kW / 102 bhp (basic engine) to a future 184 kW / 250 bhp.
The three four-cylinder FSI models with direct injection (homogenous) are rated at 85 kW / 115 bhp, 110 kW / 150 bhp and ñ in the case of the Turbo-FSI ñ 147 kW / 200 bhp. In the fourth quarter of 2005, a 3.2-litre V6 FSI with the aforementioned 184 kW / 250 bhp will complete the high end of the range.
Each of the three TDI offered is being used in this series for the first time. They are rated at 77 kW / 105 bhp, 103 kW / 140 bhp and 125 kW / 170 bhp, respectively. The Passat TDI will also be available with a diesel particle filter. The most powerful TDI features the innovative piezo pump-jet high pressure injection system.
Petrol engines:
four- and six-cylinder engines with a power range of 102 bhp to 250 bhp
1.6 with 75 kW: The basic 75 kW / 102 bhp engine of the new Passat series is both proven and economical. It accelerates the saloon from 0 to 100 kph in 12.4 seconds, gives it a top speed of 190 kph, and consumes an average of 7.7 litres of unleaded premium petrol over 100 kilometres.
1.6 FSI with 85 kW: The "smallest" direct-injection petrol engine in the new Passat develops 85 kW / 115 bhp. With it under the bonnet, the saloon is capable of 200 kph, and takes only 11.4 seconds to reach 100 kph. And this consuming a mere 7.5 litres of unleaded premium petrol over 100 kilometres.
2.0 FSI with 110 kW: The next level of motorisation is also provided by a direct-injection petrol engine. This four-cylinder has an output of 110 kW / 150 bhp, allowing a top speed of up to 213 kph and sprinting from 0 to 100 kph in only 9.4 seconds. The EU overall fuel consumption is 8.2 litres.
2.0 T-FSI with 147 kW: Volkswagen's most powerful four-cylinder is the 2.0 FSI with turbocharger and boost intercooling, which is already familiar from the Golf GTI. This 1,984 cc. direct-injection engine develops 147 kW / 200 bhp at 5,500 rpm, catapulting the Passat to 100 kph in 7.7 seconds and on to a top speed of 236 kph. This highly efficient combination of FSI and turbocharger is demonstrated by the average consumption of the Passat 2.0 T-FSI: just 8.6 litres.
At 10.3:1, the 2.0 T-FSI has a high compression ratio, and its powerful torque (280 Newton metres between 1,800 und 5,000 rpm) make it a very superior drive unit. To be precise, the Passat engine exploits the advantages of homogenous direct injection, and combines them with the superior power of turbo-loading. The result is an extraordinary torque curve, excellent response, pure joy of motoring, and not the merest hint of a turbo weak spot.
Turbo Diesel:
two 2.0 litre TDI (140 and 170 bhp) and one 1.9 litre TDI (105 bhp)
The Passat's three TDI engines meet the EU IV exhaust standard by virtue of internal measures alone. On top of that, they use a new generation of ceramic glow-plugs that lower the emission of particles even more, and at the same time optimise cold-start performance.
1.9 TDI with 77 kW: The economical, high-torque world of TDI engines begins for the Passat at 77 kW / 105 bhp (4,000 revs) und 250 Newton metres (1,900 revs). The Passat 1.9 TDI has a top speed of 188 kph, accelerates to 100 kph in 12.1 seconds, and has an average consumption of 5.6 litres of diesel over 100 kilometres.
2.0 TDI with 103 kW: 209 kph is the top speed of the 103 kW / 140 bhp (at 4,000 rpm) Passat 2.0 TDI. The four-cylinder engine develops a maximum torque of 320 Newton metres as low as 1,800 rpm, and takes just 9.8 seconds for an easy 0-100 kph sprint before reaching the top speed of 209 kph. Average consumption: 5.9 litres. This TDI performance level can be combined with a diesel particle filter.
Numerous details were modified in order to facilitate the use of an optional, additive-free diesel particle filter in the 2.0 TDI. Some examples: in order to allow the DPF to be mounted as close to the engine as possible, the position of the exhaust turbocharger was changed. The pressure with which the pump-jet element injects fuel into the slightly modified combustion chambers was also increased to as much as 2,400 bar. In addition to this, the pumping characteristic of the pump-jet was modified to allow additional injections for the thermal regeneration of the filter or other reasons. Engineers concurrently succeeded in further reducing the oil consumption, another measure to increase the efficiency of the DPF. The diesel particle filter is maintenance-free, and forms a modular unit with the oxidation catalytic converter.
2.0 TDI with 125 kW: The second 2.0 TDI, fitted with highly innovative piezo pump-jet high pressure injection and a compensator shaft, is a completely new design. This very quiet, four-valve TDI has an output of 125 kW / 170 bhp (4,200 rpm), develops a torque of 350 Newton metres (1,800-2,500 rpm), and accelerates the saloon to 100 kph in just 8.7 seconds. The top speed is 223 kph. Here, too, the average fuel consumption is low, at 6.1 litres over 100 kilometres.
Technically, the 125-kW TDI, with its switched induction manifold for turbulence control, is based on its 103-kW equivalent without diesel particle filter. This cultivated engine is the world's first piezo pump-jet TDI. Further technical features are two compensator shafts (reducing secondary vibrations by up to 80 percent), a maintenancefree diesel particle filter, and an injection pressure of up to 2,200 bar. The specific power of the 2.0 TDI, at 62.5 kW per litre, is a new best. Although the new TDI has power and convenience characteristics that come very close to those of a five- or sixcylinder turbo-diesel, the consumption and emission figures are in the low four-cylinder range.
Technologically, a central factor in the achievement of high power and convenience values together with low consumption is the use of the newly developed piezo pump-jet elements. Using one of the piezo actuators to control the high-pressure valve of the pump-jet permits:
· -very high injection pressure, and thus low emission and optimum specific power.
· -ideal hydraulic efficiency because of the very small highpressure volume.
· -ideal injection process.
· -very precise, low-volume pre-injection at a low pressure level.
· -flexibly controlled pre- and post-injection and injection intervals.
· -low injection noise.
A further innovation in the TDI is the use of a newly developed compensator-shaft module. The term "module" is easy to explain: the two counter-rotating compensator shafts (turning at twice the engine revs), together with the oil pump, form a separate module located under the cylinder crankcase. The compensator shafts noticeably reduce the amount of vibration that is transmitted to the bodywork.
Dual clutch transmission (DSG):
the DSG is internationally the most sprightly, most economical automatic transmission
Dual clutch transmission (DSG): Both of the 2.0-litre TDI are paired with a manual six-speed gearbox as standard. There will be an optional alternative: the innovative dual clutch transmission (DSG). The DSG has six forward gears, shifts very quickly, and is regarded as the ideal transmission in combination with turbo diesel direct injection engines. In the case of the TDI, it is the first transmission world-wide that fully preserves the low fuel consumption of a diesel in spite of automatic gear-shifting functionality. Like the classic Volkswagen Tiptronic, this transmission can be shifted manually via a plus/minus lane. The DSG will also be available for the most powerful petrol engine in the Passat range, the 3.2-litre V6.
Automatic Transmission:
six-speed automatic for the four-cylinder petrol engines
Tiptronic: The petrol engines rated at 85 kW / 115 bhp, 110 kW / 150 bhp and 147 kW / 200 bhp can optionally be combined with a convenient six-speed automatic transmission (Tiptronic). In series, the petrol engines of 115 bhp and above will come with a manualshift six-speed gearbox.
