Volkswagen W12 Concept

Volkswagen W12 Concept is equipped with six liters 12-cylinder engine, which is a mid-mounted and weighs 1200 pounds. It develops a maximum torque of 620 Nm at just 5,800 rpm and reaches a top speed exceeding 350 km / h acceleration of less than 3.5 seconds to 100 km / h.

This design study that systematically targeted for high performance and high levels of driving dynamics, the third phase development of two W12 concept car that preceded it. This project is a sports car, with its W12 engine inspired by the world of motor racing, entering a crucial phase of production development.

The basic layout of the W12 engine is made up of two thin modules, four-valve V6, which is configured at an angle of 72 degrees with a joint crankshaft with seven main bearings for the ALS scheme, ie a "W". cylinder angle is 15 degrees during the two V6 banks. This building, which is very compact in comparison to V12 engines, possible.

All other details about the construction of the W12 engine is a compression ratio of 0:01, is also indicative of a very high-tech device: plug centrally located in the pent-roof combustion chamber so that optimum combustion is possible, as is the flow-optimized intake port. Double-flow magnesium variable intake system mainly supports dynamic torque curve. Variable intake and exhaust valve timing has a decisive influence on the development of the electricity: input camshafts can be continually updated to 52 degrees and the corresponding values ​​for the exhaust camshaft is 22 degrees.

enormous power transferred to the rear wheels via a sequential six-speed transmission and rapidly changing behind the engine. It is very good for the classic sports car look. contact with the ground is done using a specially developed 19 "magnesium wheels with tires 255/35 ZR 275/40 ZR front and rear tires.
