Ham did say he heard Vettles car missfiring though.

true as did the commentators say his exhaust sounded fcuked just after he lost power

That is what any engine sounds like with either a broken header or broken/fouled spark plug, ask me how I know?

I remember reading someone where I think it was in autosport mag that one of the top teams made a mistake in the design stage and designed a car with a fuel tank that was too small

Theres no need for him to play those games. He's not involved with the F1 team anymore. And whats to gain?

Old habits die hard.

They all like playing mind games it's part of the sport Lewis does is it as well, for example Lewis said Red Bull have a big advantage which puts pressure on Red Bull if they don't achieve such as Bahrain it also takes the pressure off McLaren because they are not expected to be as fast while at the same time it annoys Ferrari because they are not getting credit for performance.

Possibly so yet highly unlikely imho. As mentioned in the Bahrain thread Vettels pace picked up which was clearly visible especially after Alonso's pass, atleast enough to keep Massa at bay and his timesheets should show it aswell. My point is that if it was a low fuel situation Vettel's times would have dropped drastically due to 'fuel starvation' during cornering. My guess is that Vettel adjusted to the power loss by keeping up his cornering momentum while staying out of the throttle thus making up for the power loss on the straights.

Just another outlook .

I think I can go with this theory rather than the he was running out of fuel one, having only just watched the race 3 hours ago (was offshore for the race) Vettel sounded a bit surprised over the intercom when he reported the problem

[What's Burning?]

Like others have said you could CLEARLY hear the misfiring going on whenever they switched to Vettle's on car camera. That being said though, they have the worst fuel efficiency on the grid so they are certainly carrying more fuel than others which doesn't help.

I think the winning constructor this year will be the car with the broadest "sweet spot" in performance with a heavy fuel load.

What's this about it being a thirsty car? I'm sure that the Red Bull has the best fuel efficiency. Hence why it can be fuelled lighter ahead of the race...

I will stick with the spark plug explanation. I hope that Ron Dennis is not right. Obviously the reliability of the Renault engine is causing a few issues, as we saw with Mark Webber's start.

What leads you to this conclusion, none of us truelly know the truth?

Hence why it can be fuelled lighter ahead of the race...

Did I miss something, please enlighten me?

I find it odd that Webber seem's to have more issues than Vettel?

Can't find a link now but I've read it in a couple of places, speed tv and gpupdate both had stories on it. And correction, Ferrari were the thirstiest engines followed by renault, then cosworth and merc were the most efficient according to what I read.

but that was last years figures. I am sure that some work was done over the winter to make it better. In areas other than what you would imagine

Fuel is a subject often discussed in Formula One circles, but nearly always in relation to its weight and repercussions on speed, or its role in pit stop strategy and the distance a Formula One car can travel before it re-fuels. Interestingly, what is often overlooked and rarely considered is what fuel does inside the engine to achieve performance in these areas. Shell and Ferrari work closely together to develop their fuel advantage in this respect.
Mike Evans, Shell Formula One Fuels Development Project Leader explains, "In recent times, our technical partnership has seen the development of Shell V-Power race fuel, which is designed to provide Ferrari with three main advantages - first, give the engine more power and responsiveness through optimised formulation and friction reduction; second, improve fuel economy; and third, offer protection and increase the reliability of the engine."
One of the latest fuels developed by Shell contains Friction Modification Technology. Targeting mainly the piston rings, the technology is designed to help the engine turn more freely, unlocking valuable energy and helping improve horsepower. Formulated with powerful cleansing agents, the fuel also helps improve responsiveness.
Fuel economy is an ongoing development area. In Formula One, an extra lap before pitting can mean the difference between a win and a loss. Evans says, "We measure fuel economy on a gravimetric basis - that is the weight of fuel used for a certain distance, rather than volume. Shell's objective is to create a lighter fuel. For example, say a Formula One fuel tank holds 100litres. If the Shell V-Power race fuel we create weighs a kilogram or two less than a competitor using the same size tank, then we could potentially give Ferrari an added lap advantage."
The third major advantage Shell V-Power race fuel is designed to give Ferrari is engine protection and reliability, essential in the age of the two-race engine lifespan. In this area Shell Helix motor oil works together with Shell V-Power race fuel to help provide comprehensive protection. Evans says, "Shell is very proud of the fact that we helped Ferrari reach a strong engine reliability record. By combining Shell V-Power race fuel with a suite of other Shell products, we create a complete package of care for Ferrari's engine."

It makes sense. It would also explain why Vettel stopped his car just after the finish line. To make sure there was still fuel in the tank.

But it's clearly a lie. Mark Webber had no issues with fuel. As a few people said, the engine didn't sound right. Plus, it hardly looks like a car with a small tank. It's a very long car and has the most fuel efficent engine. The problem was also intermitent according to Red Bull, which explains the wide variety of lap times.

So overall, I'd say its rubbish.
