That’s some fairly gentle testing by modern standards.

nothing say's Bentley like an overstressed, screaming motor  Increase the displacement/torque and be done with it.

enroz said: Other details he was happy to share was the Bentley have only just recently broken even after their take over by the VW group, and that unfortunately their horrid off road concept vehicle has gone down a storm with Bentley customers,if not the general public and press, so this could get the green light! As horrendous as that off roader is, if blind people with more money than sense want to support Bentley and effectively support their W12 tuning and other concepts, then get building!

I think that V12 powered trolley looks a formidable piece of kit...

GranCab said: Being old I have had in no particular order, straight 4,straight six, v4, v6, v8, flat twin, flat 6. I really really want a v12, a w12 is technically interesting but doesn't have the same ring to it. Good choice above, oddly the 612 appeals to me most.

This possibly explains the rather finger-in-the-air 200mph/20,000mile approximations.
Whatever - it's an engine screaming, quite literally glowing red hot, for days on end. I know they do the same with modern bike engines during development, so I'm sure it's the same for all modern engines. Astonishing the punishment these things can take! Full load- 6000rpm, 100hrs, no fuel stops, service interval at 50hrs. Oil level check(s) more frequently if it's an early development. To be honest it's a standard VW durability sign off test.

k-ink said: I am in awe of the bench testing. No wonder tuners can safely extract more power from VAG engines! However, it is hardly a unique characteristic. One or two other engines also have a decent amount to give without undue stress. Also, VAG engines aren't exactly perfect in reliability terms.

4 x 100-hour sessions at full throttle. Scuff test: Cold engine revved to rev limiter 100 times within 30 seconds of a -10c cold start? Totally bloody brutal - says a lot about modern lubricants and manufacturing/material science tho. I wonder what the engines looked like after these tests, wear, tolerances etc...

Seemingly impressive, but do we have the empirical data that demonstrates that these tests yield a more durable engine? That is, do recent Bentley's with these motors have far fewer failures than their competitors? Or are these testing numbers just 'fun facts to know and tell'? Separately, I still don't quite 'get' the W12 Turbo Bentley's. Pushing a barge through the air at great speed may be worthy of some regaling at the club, but it seems as useful as a fish with a bicycle. If you want to hustle down an 'A' or 'B' road, get some super GT car, or a sports car and really go for it.

Thats some serious testing right there, as for the power increase of 30bhp will it be a big difference, unless they make further weight reductions...

TBF none of this is groundbreaking stuff is it?
Look what Honda do to their timing belts.
70 Hours. This is how long the ‘heat test’ for the Honda Timing Belt lasts. Firstly a belt is heated to 125 degrees for 70 hours. The belt is then boiled in oil for another 70 hours and finally it is driven the equivalent of twice around the world.

The belt is then boiled in oil for another 70 hours and finally it is driven the equivalent of twice around the world. At 30 mph. So who cares - the belt on the average shopping car will last a lifetime. We're talking here about a 205mph supercar. Hello Honda?

Stuff like this always impresses me, and I get to see the engines being abused on test beds pretty regularly. It's amazing what they can take, but even more amazing when they fail....there is a reason test beds look like bunkers

The Bentley "Off Roader" has received the go ahead but with different front and rear treatments so said a Bentley man to me at Goodwood FOS and the expected additional profits will help the company offer more car choices in the future. The W12 Coupe will be differentiated from the V8 by more performance as the lighter V8 is almost as fast as the current W12 if not faster in real road journeys (with bends). This great news means that UK Plc will have a real rival once again to AMG badged bollides. Apart from the german assembled engine the rest is pretty much UK Plc. For us perusers of the classifieds it means more Bentley bargains around £20k in the next two years, which will make it a steal if you do less then average mileage.
I just hope the prevalence for black, silver and grey colours has a few more reds and blues in the palette as the red one I spotted in Arundel recently was simply gorgeous and with the quilted leather was beautiful. James the Red Engine it was!

I was under the impression these had weak 'rods, which is why nobody uses it as a racing engine (yet)
And why the tuners aren't getting more than 700bhpish from them.

that sounds like standard durability testing to me, frankly i would expect any modern engine to pass that with ease. this on the other hand, impressed me ford ecoboost v6 torture test http://www.youtube.com/watch?v=seKk4633Heo
