How many DNF's have RB suffered due to engine failure (inc components such as spark plugs)

And here's a quote from the start of this thread back in April ....

oops!

Only the one in Korea.

The Bahrain spark plug failure lost Vettel P1 and resulted in P4 in the end. His other technically influenced DNFs were caused by wheel rim/nut failure when he ran P1 in Australia and suspension failure in Q3 in Turkey which dropped him behind Webber on the grid with the known consequence of the collision in the race.

The one stat i find totally amusing is the Cosworth CA2010 one, the fact the CA2010 hasnt suffered any blow-ups is amazing i think. They have left blocks aside, but none have blown yet... Ferarri, Renault and Mercedes have all had at least one, but Cosworth none.

At least not to my knowlege anyways.

Very good point. Cossie always had a good name in engines though I guess.

One could argue that most of the teams using Cosworth engines were perhaps not punishing them as much as say those using a Merc lump, but that's not the case for Williams who seem to have been fairly fast this season.

I think credit is therefore due to Cosworth for producing a fairly decent engine.

Vettels engine failure was a Con Rod failure, and will now race with engine #4 for Brazil, whitch is the engine he used in Monaco and Singapore, so not too much damage on it as it has 1100km on it according to Peter Windsor on Twitter.

Id expect Webber to use his Korean engine for the remainder.

Halilton should use his Monza-Singapore engine here.
Alonso will use his Spa engine here
Button, im not sure of.

But the Q3 suspension failure wasn't what put him out of the race. Turning right into his teammate did that. So Turkey was not a technical DNF; it was a driver DNF.

I have a question about the regs. Say a driver blows his engine on the last lap, while on the run down to the finish. the car has got enough momentum to roll to the line. What happens then? Will he be classified or classified as a DNF? Or will he be considered as having finished the race?

I know nascar is as long you cross the finish line, then you should be counted as running i would think that all racing series does as well

I know I asked about DNF, but actually it would have been better to ask about technical failures (because not all lead to a DNF). Fortunately WB answered the question I meant to ask!

Postitions are awarded to the order in which cars cross the line. IMHO Raymond's example woudl be classified in the order it crossed the line.

Also cars which are lapped only get to finish their curretn lap once the race winner has crossed the line. They stil get classified, but there is a cut off that cars must complete 90% distance. So a car that stops after completing 90% distance will still be classified. This can lead to some odd results....

Lets say a car is in P1 on the last lap and the top 6 cars are on the same lap, all the other cars have been lapped. Say the P1 car stops on that last lap, then it will drop to 6th becaue the cars in 7th and below are unable to unlap themselves past the sationary car.

The way I understood it is that no driver can start a new racing lap when the leader has picked up the chequered flag and won. I was just wondering about the engine blown question because of Interlagos 2008... Thinking about how the championship was very literally won at the last corner of the last lap.

Case study Button, Austrailia 2005.

He pulled up just 4.3 meters short of the finish line, and missed out on a points paid finish, and was put in with the classified finishers, and from what im led to belive, anyone within 10% of the lap distance is classified, so at Monza, the 44 laps equates into 4 laps, meaning anyone up to lap 39 is classified. Monaco is 79 laps long, meaning anyone up to 8 laps short is classified.

Thats the general rule of thumb.

However, if a engine blows under the current rule, thats you down to 7 blocks.

That's not the same though.... my question was if the guy rolled over the finish line. Button stopped just before it

Unless the vehicle was dangerous, then I'd expect it to stand. It would also have to be in a good enough condition to pass scrutineering.
