If there was ever any proof needed that Volkswagen was seeking to bury its proletarian background and join the other German manufacturers (Porsche, BMW, Mercedes and some of its Volkswagen stablemates such as Audi and Bugatti), at the top end of the market, it is the existence of the W12 Coupe.
Originally thought to be a concept car, the W12 took a huge leap forward last October when VW rolled it onto the racetrack and set a raft of performance and speed records, the most convincing being that the W12 averaged a staggering 294 kmh/183 mph over 24 hours.
This time the W12 smashed its existing world 24-hour speed record by 27.7 km/h, covering 7,749.4 kilometres at an average speed of 322.89 km/h - that^s an extra 663 kilometres in the 24 hours.
Whilst these speeds in their metric guise may just seem ridiculously high to many of Gizmo^s readers, convert them to imperial measure and you^ll suddenly understand why VW went back to the racetrack.
The February records have now pushed the average speed past 200 mph for all records from 100 kilometres and one hour, through to 5000 miles and 24 hours.
Accordingly, the W12 is capable of averaging 200mph almost indefinitely, which makes it one weapon of a roadster.
At the heart of the W12 is a 440 kW (600 bhp) twelve-cylinder engine in a W configuration, which perhaps not necessarily by coincidence, is becoming the VW hallmark.
In the future, all Volkswagens in the upper and luxury classes will be equipped with the high-torque W-configuration engines, which are characterised by exceptionally low levels of vibration and the best possible acoustic qualities.
The Volkswagen Passat W8 is already using an eight cylinder version of this configuration, and the 12-cylinder engine will power several other Volkswagen Group upmarket vehicles, including the new Phaeton luxury saloon which debuted at the Geneva Motor Show earlier this month and a yet-to-be-released premium off-road vehicle - in both cases, the 6.0-litre engine will be in a lower state-of-tune, producing 309 kW/ 420 bhp.
A 16-cylinder version has also been developed and will be used in the beautiful Bugatti Veyron.
The engine is compact, harmonically balanced and ... awesome
The 440 kW, six-litre, 12-cylinder engine is made up of two very thin V6 four-valve modules which are configured at an angle of 72 degrees with a joint crankshaft with seven main bearings to make up a V-V or W configuration.
The cylinder angle is just 15 degrees within the two V6 banks. The engine is mid-mounted in the W12 and with a length of 513 millimetres, a height of 715 millimetres and a width of 710 millimetres, is particularly compact. At 239 kilos, the engine is also very light. A further indication of the systematic light-weight construction approach taken by VW can be seen in the valve and timing-chain covers, which are made of magnesium.
The engine, which is located between the passenger compartment and the rear axle, has an extraordinarily torsionally-rigid aluminium crankcase with wear-resistant cylinder sleeves. All other construction details of the W12 engine, which has a compression ratio of 12:1, are also indications of an extremely high-tech assembly: the spark plugs are positioned centrally in the pent-roof combustion chamber, making optimal combustion possible; the same applies for the flow-optimised intake ports.
A double-flow magnesium variable intake manifold supports the particularly dynamic torque curve. The variable intake and exhaust valve timing has a decisive influence on power development: the inlet camshafts can be continually adjusted through 52 degrees and the corresponding value for the exhaust camshaft is 22 degrees.
At 5,800 rpm it develops a staggering 620 Newton metres of torque and its top speed is in excess of 350 km/h. The W12 Coup^ truly is one of the most exclusive and fastest sports cars in the world. Running gear - Double wishbone suspension and Brembo brakes system The enormous power of the engine is transferred to the rear axle via a sequential and thus very fast shifting six-speed gearbox located behind the engine.
The contact to the road is made via specially developed 19" magnesium wheels with 255/35 ZR front tyres and 275/40 ZR rear tyres.
The sophisticated front and rear axle with double wishbone, numerous electronics modules, an ideal weight distribution of nearly 50:50 and an extended wheelbase of 2.63 metres ensure that the W12 Coup^ is both fast and safe.
The scope of active safety systems includes the electronic stability program ESP and the traction control system TCS. The performance of these systems in the correction of the vehicle response is carried out not only via the brakes system, but also via the central engine management system.
At the same time electronic differential locks (EDL) ensure via the brakes that the wheels do not overspin at speeds under 40 km/h. Anybody wanting to drive the W12 Coup^ on a racetrack can deactivate the electronic running gear systems. The basic concept of the brake system has been perfectly adapted to suit these situations. Ventilated Brembo brakes with a disc diameter of 318 millimetres have been fitted at the front and rear. The handbrake has been designed for comfortable standard production: it is activated electronically by pressing a button.
