RR/Bentley. 6.7 V8 or 6.7 V12.

How do you good people rate these engines, as in, which is the better lump?

My niece asked me this tonight and i thought i'd pass!

I think the engines used by Rolls Royce and Bentley in recent times are:

4.4 BMW V8
6.0 Volkswagen W12
6.75 Rolls Bentley V8
6.75 Rolls Bentley V8 Turbo
6.75 BMW V12

So, in your ultimate luxo-cruiser, would it have a V8 or V12 lump?

Also the 6 litre W12 VW engine. Which would be my pick, and the turboed RR V8s pack enormous punch too. They'd be second. Not that I've driven either, mind!

Its got to be the big crewe V8. Lovely old engine and designed for the car in the first place. The BMW V8 or W12 nonsense are just examples of a stock engine being shoe-horned in by the then owners. The 6.75 V8 is the real deal.


Even Bentley now recognise this, because the current Arnage and Brooklands contains a refined and updated version of the classic V8 motor rather than a cut and paste job from a VW.

Surely the only ones to have are the middle two..no brainers really.
My Dad has the 6.75 Bentley V8 in his, its never missed a beat in 4 years.

I think the V8's will feel more urgent somehow. But I like the W12 engine (I have one at the moment) and it compares well with a V12 (such as the Vanquish). I'd go 12 cylinders...

I was fortunate enough to have spent a day with a Rolls Royce Seraph, which had the BMW V12 engine. That was superb, I preferred it to the old warhorse Crewe V8 actually. As for the BMW V8 that was fitted to the early Arnage, bloody awfull thing. Smooth yes, technically advanced yes, but bloody awfull nonetheless. When they put the old engine into the new car, they got it right at last.

Wasn't that engine the one with quite a modest output, around 300 bhp from 5 and a half litres?

I am thinking that the best engine of all is probably the latest Phantom 6.75 V12, non?

[Beemer-5]

2007 Phantom.

We know someone living in Paris with one and the engine is astonishingly good, i think.

80% of peak torque is available literally just over tickover and over 450 easy ponies are waiting to be unleashed without ever breaking sweat!

Probably. I think it's the latest incarnation of what was the Seraph engine, and the BMW 760 engine isn't it?

Although the original 1936 Phantom III 7.2 V12 was quite something.

(especially with an Austin Seven engine mounted on the running board to power the supercharger as some absolute nutter had back in the day).

I can only comment on the 6.7 V8, but I do love it.

Smooth, "woofly", warbling, but still with that unmistakeable V8 undercurrent; everyone who has heard it on startup always goes, "Phwoarrrr! Nice!".

Looks nice as well:

I never knew the new engine was a development of the older 5.5!

Either way, driving along the busy Boulevard St Michel and out to the suburbs was amazing in the Phantom.

Don't quote me on that, this is the internet afterall

[Beemer-5]

That's a point, BG and glad you are back in the fray!

Still miss the old mans T-Series, much waftier than the replacement...

I always remember with great affection the sound of Bader gently swelling up from the bulkhead in a mid 90s Brooklands number.

A V8 6.75, of course, spiced only with a light pressure turbo (aka LPT in the txt of ads,) it is estimated to have made a measly 300bhp but combined with the compliance of the springy bits, made for fabulous progress.

Not at all fast but irresistably imperious.

[Beemer-5]

The Phantom looks like the gawd-knows-how-many-tons-it-is but never felt it once rolling.
