Superior W8 engine complements the worldwide success of the V6 versions

Press Release

Start of a unique product offensive Superior W8 engine complements the worldwide success of the V6 versions Europe's most successful automobile manufacturer has opened a new chapter in the seventh decade since its foundation. With the Passat W8, Volkswagen's first eight-cylinder model, the brand launched a broadly based product offensive in the luxury class and C segment. The Passat W8 with a power output of 202 kW/275 bhp fulfils two tasks. On the one hand it bridges the gap to luxury class saloon, the Volkswagen Phaeton. Secondly, the Passat W8 extends the range of products above the successful V6 models. The V6 Passat has been successful for many years in the premium end of the B segment. However, the new Passat W8, with its completely redesigned engine and drive system, is positioned in the C segment. Another exclusive feature which contributes to its special status is four-wheel drive fitted as standard. The relationship between comfort, drive technology and price has secured the new Passat W8 a unique position in the luxury class. This alone makes it superior to its competitors' six-cylinder engines. In addition, their eight-cylinder models are some twenty percent more expensive than the Passat W8. As with all Passats, the Passat W8 is also available as an estate car, and Volkswagen expects the estate to be a popular choice. The W8 tops the V6 and enters a new class Volkswagen traditionally enjoys a strong market position in the premium mid-class - last year, the brand sold over 75,000 Passats with the V6 engine. The new Passat W8 will satisfy the wishes of particularly discerning Volkswagen customers. Surveys of the US market have demonstrated that interest in the eight-cylinder model, as an extension of the range, is particularly strong. Some 710,000 vehicles were sold in the C segment in Europe in 2000, of these over 282,000 in Germany. The Passat W8 is set to conquer new shares in this market. Volkswagen expects a conquest rate of up to 70 percent and is convinced that the new model will particularly appeal to the progressive, independently thinking customer. Sales for 2002 are expected to total 10,000 units, with an equal split between saloons and estates. According to Volkswagen analysts, some fifty percent of Passat W8 drivers will be recruited from existing luxury class customers, and over one third will be going upmarket from the upper mid-class. The primary target group comprises managers of medium-sized and large companies, self-employed people, owners of companies, and discerning private customers. Powerful acceleration, high top speed and smooth running Details of the new engine: the brand's current top model has a redesigned eight-cylinder engine. From its 4.0 litre capacity, the W8 develops a power output of 202 kW/275 bhp at 6000 rpm and a torque of 370 newton meters at 2750 rpm. The 32-valve engine combines its confident power development with an absolutely smooth engine. This basic feature enables it to be both a dynamic sporty engine and give a comfortable ride. Volkswagen engineers have limited the maximum speed of the new high-end model to 250 km/h (155 mph). The saloon with manual gearbox completes the zero to 100 km/h dash in 6.5 seconds, the estate in 6.8 seconds. With Tiptronic, the same sprint takes 7.8 / 8.1 seconds. EU standardized consumption for the saloon - for both the manual gearbox and for the Tiptronic - is 13.1 litres of premium petrol over 100 kilometres (18mpg). The different aerodynamics of the estate give it a fuel consumption of 13.2 litres / 100 kilometers (17.8mpg). Volkswagen high-tech: W-layout and four balancer shafts The W8 engine basically comprises two V4 modules offset at an angle of 72 degrees. Their internal cylinder angle is a narrow 15 degrees. This double V results in a W layout. In addition to the crankshaft with five main bearings, the W8 has six other shafts. Four of them are the overhead camshafts manufactured by internal high-pressure forming which are driven from the intermediate shaft via simplex chains. There is one inlet camshaft and one exhaust camshaft for each cylinder head. The valves are actuated by roller rocker fingers to reduce friction. The engine's unusually full torque is partly due to continuous adjustment of the inlet camshafts through 52 degrees and the exhaust camshafts through 22 degrees. An aluminium resonance intake manifold further enhances acceleration and power development. The extreme smoothness of the engine up to its maximum engine speed of 6400 rpm can be partly attributed to the two Lancaster principle balancer shafts which improve mass compensation. They are fitted one above the other, and are symmetric to the middle of the crankshaft. The two balancer shafts counter-rotate at twice the crankshaft speed, the upper one is driven by a maintenance-free toothed belt. The crankshaft is made of tempered steel. The "flat" crankshaft design has a crank pin offset of 180 degrees and a firing order of 1-5-2-6-4-8-3-7, a typical feature of high-performance engines.
