WOW

Mind you i bet i could get a dodge viper engine to churn out 1000 hp. Being cast iron , it should not warp.

is not the engine thats the problem its the transmission and getting it to last the lifetime of the car.

oh

For some reasion i am always under the impression that american cars all have cast iron blocks.

here we go

Engine Design


90-degree V10. cast aluminum block with cast iron cylinder liners,
aluminum heads and crankcase

At £850,000 it might sound like a lot (?!) but they're supposed to cost £5m each to make...

For more info go to the Buggatti site

"Go to www.bugatti-cars.de
Choose "English".
Along the top, click on "Models"
Choose "Veyron 16.4"
Choose "Engineering"
Choose "Engine"
Along the bottom, choose "Legends from 1001 HP"
Click on video segments 1 through 7 in sequence. You may have to click the play button (small arrow) to get them to play initially. "

The Viper engine started life as a truck engine. (Americans try not to do diesel). Then someone said "what would it be like if we put one of these in a car?" and so the Viper was born. Chrysler owned bugatti or lamborghini or someone and they shipped their cast iron 8 litre V10 truck engine and said "make it good". They got back their engine cast in aluminium and tuned up to 400 or 450 BHP - not a lot from an 8 litre lump. In time it was retuned to 500 BHP and then enlarged to 8.2 litres. You'd think they could get a bit more out of it if they tried.

These engines are sold brand new in crates to car modifiers in the US. I bet you could get one shipped over here to put in your locost. You might need to enlarge the engine bay a bit. Or you could put a good engine in it.

No what if one of those bugattis were to find its way into a breakers. 1001 BHP in a locost?

This is one i believe

I have allways wanted an MTB, and thought the Viper lumps would do nicely to replace the old engines

Is there a piccy of the Veyron's engine somewhere? It might give me inspiration as I tinker with my ickle V6

there was a w12 on ebay a little while back which was linked on here, probably looks similar, just a little longer

homer mode/ arggggllllarrrrrggggllllarrrrrahhhhhhhomer mode

my understanding is that if a car costs 5m to make and you sell it for 800k or so, you dont actually intend to sell many (or any) at all, and its just a publicity excercise....

... and Bugatti is owned by the same company that owns Lamborghini..... R&D is never wasted

I work in electronics R+D

My understanding is that the head of Volkswagen wanted to build the fastest road car of them all and gave the designers free reign to do it.

It took them a while and cost a lot of money, but it was a success in terms of publicity and technical experiment.

Volkswagen have the money, so they thought what the funk and did it.

They might make a loss on it, but they deserve credit for coming up with such an insane beast.

agree. I did however think it daft that clarkson banged on that the gearbox had to be strong in order to take the power over the life of the car. If you are not going to sell many, and they prob wont do that much miles, its a bit irrelevent.

I think the 'free range engineer' tone of the car was set when he said it had 4,000 quid titanium indicator stalks.

The transmission needs to be reinforced or when they did break, VW would get a lot of bad press over it. If it broke after only 3 or400 miles Volkswagon would be laughed at for wasting their money. Mind you i bet a truck gearbox (with some modification of cource) would have done the job as there are some with way more than 1000hp these days.

I sometimes deliver to a place that services and repairs trucks..

I was talking to those guys and so they were saying the boss has a twin supercharged straight six engined MAN truck kicking out somewhere in the region of 1500 horses.

The torque out of that thing would be nuts.

An article in the latest NUTS magazines shows a Dodge Viper tuned to 1000bhp with a top speed of 255mph. You could but 6 of them for the cost of the Bugatti!!!!!!!!!!!!!!
Plus its got the engine in the right place, up front with a nice long bonnet.

Hmmm Bugatti's own figures seem to be at odds with the ones in the press. they only claim a top speed of 248mph and 0-60 of 2.8 seconds......... making it about the fourth fastest road car in the world........ (behind both the tiger and the ultima! on acceleration)

[Edited on 17/12/05 by DaveFJ]

the top speed is 252mph as this was done a few months back at vws test track, the acceleration hasnt been achieved in any public test as far as i know, the fastest ive seen is 2.7s.

the whole point of the bugatti exercise was to make a usual ultra high performance car, every review has said that its almost too easy whereas the tiger and the ultima are like mini apocalypes the bugatti remains civilised. any car that can make the cabinso quiet taht the passengers can have a normal conversation at 180mph+ must be caryying atleast 100kg of sound deadening . so all the extra weigh will reduce accelleration which shows just how quick it really is.

Now that VW has built that engine and knows that it works, i wonder whether they will put smaller versions of engine into some of their salloons. Imagine, a W-16 vw passat
