Bentley Arnage fuel consumption

[dazzalse]

Thought I would share with you a trip we made in the car earlier in the week, Santander to Estoril, 690 miles in one day mostly motorway but apart from the comfort I was amazed to have averaged 24.1 mpg over them 690 miles. We were not hanging around and maintaining a steady 85mph. Car was fully laden with 4 of us with luggage. I have had a number of these cars over the years and this is the final incarnation, being a Final Series late registered 2009 car, she is barley run in with 7,000 miles on the clock

That's much better than I would have imagined, and it sounds like it was the perfect car for the trip.

I covered around 400 miles in my Corniche the week before last, averaging about 13mpg...just as well its a summer only car!

Any photos of your car during your travels?

I am impressed. I completed a run to the South of France recently in my 2002 Arnage T. On the Motorway sections I got 16 mpg cruising at 95-100 mph. On the "N" roads with a lower speed I got 17 MPG. They must have done something to the later models as they are supposedly more powerful. Anybody know what, and can one retro fit it!

Love to hear any more real world figures from epic drives or anyone brave to use it in city traffic on a daily basis!

So.... is it a 4.4 or a 6.75?

Being a Final Series I think that would have made it the latter.

Quite incredible really. Only around 10 mpg worse than my 1.3 in the same conditions (with a roof box).

I think that those have a 6 speed. It should make for los revving travel. A Corvette with the 6.2 can do 30 US MPG

I bought my 6.75 Red Label in France.

We drove from back from France to the UK - 757km in total.

The car was on empty when I bought it (having been unused for some time).

I brimmed the tank in France (approx 120 Euros) which got us to Dover. I filled it again, and got home with 2/3rds of a tank left.

I worked it out to be around 28 mpg - but happy to be corrected...

This was predominantly on cruise and maintaining speed limits given the fact the car hadn't been started or driven for around 3 years.

We have several large engine vehicles, and I had prepared for the Bentley to be horrific on fuel! In contrast, I've struggled to notice a difference either way to my 997 C4S / Mercedes 560SEC. I'd even go as far saying that it's better than our Range Rover SVR.

Without knowing the exact price of fuel, but doing a calculation based on what the RAC say it costs (for normal unleaded), you get the following.

£1.47 per litre = €1.69 per litre.

€120 therefore gets you 120/1.69 = 71 litres

You used 71 litres plus a further third of a tank = 94.6 litres in total, which equates to 20.8 UK gallons.

You covered 757Km = 470 miles.

470 miles using 20.8 gallons means you averaged 470/20.8 = 22.6mpg.

Probably more accurate than Chat GPT's calculations!

22.6 doesn't seem out of order for a 6.75 litre V8!
