Nope. Real person.

The "Bently Continental Flying Spur". Do you reckon they could have picked a more ridiculous name?

0-100 in 5.2 seconds for a car that weighs nearly 2.5 tonnes. Not bad!

You'd hardly call it a "drivers" car though.

The W12 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 arrangement, i.e. a W. The cylinder angle is just 15 degrees Within the two V6 banks. This makes the construction, which is very compact in comparison to V12 engines, possible.

i found this, still cant understand how the things work, the cylinder head looks like it needed some designing.

It is named after models in the 1950s, as well as the original Continental coupe there was one coachbuilder that did a 4 door version called the Flying Spur. Back then you had a choice of about 4-5 different body styles.

A W motor is effectively two V motors sharing the one crank. The difference is that the centre valley has a high spacing (I think 72deg on the Veyron) and the two Vs have small enough spacings such that they share the same heads which is why it looks like a squashed inline 6 cylinder in this previous image. The benefits (ignoring complexity) is a smaller engine length so you get a W12 for the space of say a V8 or V10.

VW have used simliar concepts on a smaller scale with their V5 motor and a more recent V6 used in the Golf R32 which had a V separation of just 15deg.

The other aceivement that volkswagon di when they made these engines was the fact they did it with only two comshafts per bank- the lever system they use to make the valves on the opposite side of the head open is very complex - esp in the fact that they can sustain decent rpm without valve bounce/float.

Rev28K · 08-05-2006, 05:02 PM

Although the W engines are compact in length, they are still hung way out front (well past the front axle line) in normal VW/Audi tradition. Have a look at a Bentley (or an Audi V10 S8) for that matter and you will be staggered how far forward they are mounted. The designers have done a very good job of disguising this.

The next time you are in a Bentley dealership (or the motorshow) have a look for yourself and you’ll see what I mean.

LethalLeigh · 08-05-2006, 05:31 PM

That's allegedy because Audi try to maximise interior space without changing the overall length. Just makes their cars understeer like mad despite quattro drivetrains.

turboute - lever system aka "rockers" like a lot of cars...

Audis have a longitudinally mounted engine and front wheel drive (the all wheel drive models are the same layout), the diff is behind the engine (and clutch until recently), so the driveshafts are behind the engine. On the current A8 they have moved the wheels forward, not sure on the detail of how this was done though.
