Running in new V8V

Well why kilometers? Bloody ridiculous pseudo scientific measurements scheme dreamed up by a short French man...
And relax....
He didn't.And relax....
He dreamed up the kilometre.
Then it was hijacked by the US of A and it became the kilometer.
Why do we adopt the American version for kilometer but maintain the original for metre ??
And relax...
Mikey, I honestly would not worry that much. I don't. My advice would be as follows :- When you start it do not let it idle, drive it. Reason. You can glaze the bores which can result in reduced power and oil burning. Do not give it the beans till it is up to temperature difficult I know but advisable. Vary the loads on the engine. sticking at 70mph for mile after mile is not running it in. Use the gears much more than you would normally, do not let her slog up hills. The net result will be a smoother quicker car. One other thing try and feed her with the best fuel you can buy. There have been reports of engine problems as a result of using cheap fuel.
My first V8 completed 5500 miles from Jan to July ran like a top and averaged 24mpg. Our new V8S has now managed her first thou. The supposed reduced fuel consumption has not materialised because we drive it in Sport all the time and keep changing gear every nano second because it is so Gooood! You will be so delighted, the S is very quick the steering is very sharp it makes one hell of a racket. Approach a corner a little too hot change down 3 times, the noise is something else steer her round no problem. I like watching the traction light flashing at me.
Keep us posted

Why do the Americans even use kilometres? Every drawing they send me is in imperial. He dreamed up the kilometre.

I presumed as much
So use but don't thrash it or labour it for ~1.2k miles

The most important part of running it in is to keep the revs down which the ECU does for you automatically until you surpass 1243 miles.
This is not true. there is nothing in the ecu to stop you from hitting the redline in any gear on a brand new engine. i advise you dont. Just take it easy for 500miles.KarlFranz said:

Please be armed with facts before you take such a stern and confident tone. From the Transmission section of the Vantage V8 Owner's Manual:
"For the first 1243 miles (2000km) and whenever the engine temperature is below 104F (40C) the shift conitrol will indicate early shift changes to protect the engine."
Those who have tested this have discovered that the rev limiter kicks in if you attempt to exceed this lower rev limit until the break-in period is exceeded.
Of course there is nothing to protect you from going 4th to 2nd gear while traveling at 140mph and over revving your engine, but no manual gearbox will prevent you from doing that.
Although the cars are bench run in it worth ensuring mechanical sympathy in the early miles -
It has been mentioned NOT to rev the car hard when cold while running in, but surely this applies at all times whatever the mileage.
For the first 1k miles-ish I would build up the demands on the engine, brakes, clutch etc to let everything bed-in. The advice to vary the revs is good, as is not overloading the engine for sustained periods, but beyond that I wouldn't worry too much. I always work on building the rev range gradually keeping it below 4-5k-ish over the first 200-300 miles then gradually upping the rev range for short periods until I'm using near full beans occasionally, then much more often as the 1k approaches. The "theory" is an engine run in aggressively, but sensibly, with mechanical sympathy will gain a few extra horses, not sure if that is true but it seems to work for me
