How long before we see a 300mph road car ?

Tzardine

Like the title says. How long do you think it will be before we see a road car which will break the 300mph barrier ?

In 1993 the McLaren F1 was the fastest with 240.1mph

This was the record for 12 years until the Veyron hit 253.81 followed by the Supersport in 2010 with 267.85mph.

With the Henessey hitting an unofficial (for now) 270.49 recently do you think it will be long before somebody get the extra 30mph or is it simply not possible for a mass produced car at the moment ?

Its easily achievable today, the problem is there isn't any track long enough to do it. If you had a long enough track the Veyron could easily be configured to do it.

I imagine it could be done on a long banked oval no problem. Its the kind of thing that a manufacturer would presumably love to be able to say their car can do.

do not they use the salt flats in utah or some place like that?

They use Bonneville for land speed records, those cars have special wheels, but the salt isn't the best for road car tests

Talladega is the fastest oval in the US and NASCARs were hitting 220mph before they had to restrict them as they were starting to go airbourne! Im not sure how a road car would handle speeds approaching 300mph, but I dont think that it would be possible on a banked oval, given the issues with keeping the cars on the tarmac, and also the G forces that the drivers would experience. They tried to run Indycars in Texas a while back and had to abandon it because drivers were blacking out from the G forces at top speed. I think the fastest that an Indycar has done on an oval is somewhere around 255mph.

I am sure they could use the Eyre Highway in Australia if needed. Close a few km of it .

It is dead straight for 146 KM apparently :eek:

If it cant be done at the Nardo Ring I cant see it being done anywhere. I also cant see many drivers volunteering to do it! Theres plenty of cars out there that are capable of 300 with from configuration mods, such as the Veyron, Ultimate Aero ect...

I don't think I'd fancy doing 300mph on that road, I'd imagine hitting a pothole at that speed would be an entirely unpleasant experience.

Yeah ovals won't work. Ehra-Lessien has a 5.5 mile straight, that's where the veyron did it's top speed test, but VAG won't let anybody else use it, so the hennessy can't get properaly compared to the veyron. But even without modification I would guess the hennessey would would push closer to 300 on that track.

I don't think the current technology to be quite up to the challenge - afterall, it took 21 years to go from 243 to 270 and, as physics tell, the higher the initial speed is the harder it becomes to increase upon it - so going from 270 to 300 is quite different than 240 to 270.

Biggest challenges would probably be to make tires that can last a bit at those speeds while still having grip and aerodynamics that while keeping the car firmly on the ground, do not produce excessive drag. It may be a few years, if it is possible at all without breaking into "land speed record" monsters.

The Dagger GT manufacturers think they can do it this year. The technology exists, it's just a matter of finding a place to do it. The whole thing is totally pointless though. Why would you buy a car that can only do it's top speed on 1 track that you will never be allowed to use, I just don't get it. Anything over 200mph is just pointless.

Correct me if I'm wrong, but I think the Dagger GT exists only in the mind of its designers, at the moment...I even see they're looking for money on their website. Also, I see they mention "M/T landspeed tires", also known as "Bonneville tires"...

As to it being utter pointless, could not agree more - especially when it produces cars which are a bomb in a straight line and a pig in the corners...

Yeah you're right, doesn't exist yet, probably a pipe dream.

Well DGT is building the 406 again so I think maybe after that??

2-3 weeks..

Koenigsegg One:1 supercar revealed

Performance details of the new Koenigsegg One:1 have been revealed. It’s so called because it’s the world’s first production car to equal its kerb weight with horsepower, its 1341kg matched by 1341 metric hp, which is the equivalent of 1322bhp. It’s also the equivalent of 100kW, or one megawatt, Koenigsegg dubbing this the ‘world’s first megacar’.

That’s more power than the Bugatti Veyron Super Sport, Ferrari LaFerrari, McLaren P1 and Porsche 918 Spyder, and the equivalent of around three Porsche 911 GT3s, our 2013 Car of the Year.

Power comes courtesy of a 5-litre twin-turbo V8 engine, based on that which produces 1140bhp in Koenigsegg’s Agera R supercar. It drives the rear wheels through a seven-speed twin-clutch gearbox and an electronic differential. Performance claims are seriously impressive; a top speed of 273mph would top the 270mph Hennessey Venom GT and 268mph Veyron if proven, while 0-248mph (0-400km/h) is completed in around 20 seconds, the car then braking to a stop in half that time.

Tires and aerodynamics is the biggest factor in the race to 300mph. Lump a 2200hp engine in a Veyron with better aerodynamics and it should be possible but building a gearbox and engine that can produce results(acceleration and top speed) time and time again without catastrophic failure like the current Veyron will take serious next generation engineering.

it's not like there's much difference between 200 and 300mph if you're on a public road, either way it won't end well

Only 17 more miles to go then.
283mph in 1 standing mile.

Impressive as it looks it is not a production car.

Would love a lend of it for 5 mins though. It would be the best last 5 mins of my life.

The GT40 is a production car, that one is obviously modified, but it's still a production car

It is a modified car. Sure I could strap a Saturn V rocket to a Micra. It would not count as the fastest production car in the world. The rules apparently are:


The list is also limited to production road cars that:
Are constructed principally for retail sale to consumers, for their personal use, and to transport people on public roads (no commercial or industrial vehicles are eligible);
Have had 20 or more instances made by the original vehicle manufacturer, and offered for commercial sale to the public in new condition (cars modified by either professional tuners or individuals are not eligible); and
Are street-legal in their intended markets, and capable of passing any official tests or inspections required to be granted this status.

Ah, I didn't realize we were talking about official top speeds, I was just talking about making a production/road car go over 300mph.

Since we're being pedantic. Adjusted cost of a Saturn V would be about 2 billion euro, so good luck investing that euromillions. Of course a modern equivalent in terms of power are only about half that. :pac:

I watched a documentary once about the Veyron. There was some mad statistic (and don't quote me on this) but to overcome the wind resistance above 220mph to get to 250mph you need an extra 300hp. As the speed rises the ratio to power increases further to overcome drag.

I'm not sure it's right to even let a (rich) member of the public have access to a car that can do 300mph. Even the McLaren P1, Porsche 918 and La Ferrari are getting ridiculous, I'm not complaining they are technical masterpieces but where does it stop!?

James may was talking about it when he drove the Veyron ss in Germany,something about the drag increasing to the square of speed.Im sure the power of the Veyron could be increased as 1200hp from an 8 litre with 4 turbos isn't huge when merc can sqeeze 355 from a 2 litre turbo.

pajo1981

Veyron @ 300mph

1200HP * (300/270)^3 = 1646HP

By my calcs

Veyron would need to be aero stable at that speed. Which it probably isn't.

What's the boost on a Veyron? It's probably relatively low compared to the Hennessy kit car/

Purely on a point of information:
100KW is not equal to one Megawatt.
Surely they mean that the car produces one Megawatt?
