GT3 can only do about 300 kph.

The First vid shows the video car doing 180KPH; and getting passed at what seems less than 100 KPH faster from the looks of it; not 200KPH faster... So I doubt that car was doing 380.
The Veyron Does it with 1001 hp; but it is also pulling over 4200 Lbs. A lighter car with proper aerodynamics could certainly do those speed figures with far less HP. The key issue for the veyron was maintaining both safety features and comfort, that's why they had to push it to 1000+ HP.
The HP itself isn't the requirement; but the HP to weight ratio along with the drag coefficient will decide how fast a car can go with a given HP figure. As a comparo; a Veyron is pulling just over 4 Lbs/HP; a GTI is pulling more like 16 Lbs/HP...

HP/weight is important for acceleration, for high speed it's all about horsepower and downforce. HP is absolutely required to displace air, otherwise a Lotus Elise or Ariel Atom would be the fastest cars on the road with their silly power/weight ratios.

I couldn't ID the car, but I can ID the driver as a Douche Bag!

Downforce itself just keeps the car planted rather than flying off the road. Downforce is a part of areodynamics to be sure, but the overall measurement of a car's ability to push through the air with minimal resistance is, as I stated already, drag coefficient
The more aerodynamic the car the faster it can go with less resistance, or drag.I did not say horsepower was not needed, only that a lighter, more aerodynamic car could do the same speed figures with less HP. You could put 2000 HP in a Peterbilt and it still could not go 250+ mph; however, the same 2000HP in a F1 car would likely put it over 300mph.

Either way diesels are meant for low rpm grunt. Apples to oranges.
Like I said, weight isn't an important detractor of top speed runs. Downforce, by definition, is artificially creating extra weight. Those F1 cars generate something like an extra ton of weight at speed, it's their 850hp that lets them hit high speeds. The low static weight of the car lets them hit that speed quickly.
Horsepower pushes you past drag, that's why there's 200mph old Pontiacs at Bonneville (which have the drag coefficients of large bricks). It takes more and more power to get each extra mile per hour, whether the car is stable at that speed is a different matter.

Ready to race!
First one Vette ZO6 socond one Porsche. I've seen the first one years before the ZR1 came out. Both ridiculously fast!

We are saying the same thing... Essentially (weight does matter, as you just proved, sorry) :thumbsup:
