Hi Chaps,

Can someone please explain one thing to me, which is that Bugatti did make a big deal about tyres having to be especially made to handle such large speed's, and on a Bugatti these things dont come cheap, so how can cars regularily hit 240+ yet dont seem to have tyres that one would have thought didn't work, and at worst started exploding of the rims.

Mr Fox

Because the whole run took 24 seconds, on a completely straight track. The Veyron is designed (if anywhere was possible) to run continuosly at 250+mph. Well, for about 8 minutes until the fuel tanks are empty. The reason the Veyron is so expensive and so engineered is because it's designed to do the things that it can, every day, again and again, like any normal car you'd buy. Not just once every few months after lots of preperationa and partial rebuilds.

Ah I see. Would you not think that this car could do 240+ for 8 mins. I mean even that stat about the Bugatti is theoretical as I'm sure it would not be achieved on any road or private 5 mile track.

Theres a video on youtube of a Koenigsegg Agera R doing 3 0-200-0 runs consecutively yet I presume they were not especially formulated for that car.

So, regarding Heffner Performances 266mph run last year, did that turn out to be an error in the timing gear or BS? As I thought that was still the title holder.

So many great cars that are pulling big texas mile numbers now - boostlogic's supra, AMS' Alpha GTR etc. Exciting stuff

The tyres on the Veyron have to be capable to driving you to the shops, driving in the rain, braking and lasting 5000m as well as safe at 250+mph without burning themselves out and disintegrating. They aren't designed to be replaced with new ones each time you want to open the taps on the engine.

What tyres is the Koenigsegg using. There are plenty of 200mph rated tyres to choose from available to the public. Who made tyres capable of 250+mph before the Veyron? No one. Hence they had to be specially formulated for the Veyron to meet their exacting requirements.

Thanks for your replies.

LOl at comments on slow start. You think it's easy getting traction in a car with that much power?

Check out koenigsegg drag races, they really struggle for the few hundred yards or so.

Quite!

I know, I`ll obliterate the tyres that I`m going to be relying on at 257mph by giving it a massive bootfull in 1st and 2nd which will also have me at a smoking standsitll!

worlds worst start????

Does he not short shift to third so he can floor it sans wheelspin??

You're not wrong! Standing mile... you'd think he'd have practiced that a bit more! Getting that right alone would get him over 260...

The car will have monster gearing to pull those speeds and its probably like starting in 2nd/3rd. Also the clutch will be somewhat updated and probably on the sharp side.

Anyway, from my limited experience of drag racing fast ET's and high terminals don't always go together.

Simply stunning, so relaxed while pounding physics into pulp. Love that car.

10+ for me, this is 100% what Pistonheads is about. Speed matters!

Quoted tyre life on the Veyron - 2,500 miles. So every 2,500 miles you'll be spending £20k on tyres. Every 10 thousand miles you've got to be changing both the tyres and the *wheels*. These are not tyres intended for daily usage. Yes, they can go down to the shops, but thats not what they're made for. If you did intend a Veyron as your daily driver, you could be having it in the shop for a day every month for a tyre change!

Prior to the Bugatti, the McLaren F1 was hitting over 240mph over 10 years before the Veyron appeared (I know, that 10 mph could make a fair difference in energy), so plenty of time for tyre technology to improve.

If you can afford a 1 million pound car, is 20k on tyres really going to bother you?

Remember the Veyron weighs about 80% more than the McLaren

It either had a seriously long first gear or he started in second.

Impressive .....but the streetbikes are doing 278mph

Not bad for a Ford

That's mental. Crap start though!!

I would prefer the lotus in this link http://www.youtube.com/watch?v=HmscSzFurwg&fea... or an orginal gt40! I do take my hat off to them engineering wise, the paint job is awful!

[tommy vercetti]

Insane.

[Jenx]

Wonder how long that engine will last.

My PH buddy on picking up a motor for his Ultima was told..."It will do 6k rpm for ever, 7k rpm for a season and 8k rpm...once"

It may well have taken the Yanks 20 years to catch on to the benefits of turbochargers (compared to massive, and massively inefficient mechanical superchargers) but they really seem to be getting the hang of things now ;-)
