I only just noticed the "bluewall" tyres, that's a nice touch!
The other nice touch regarding the tyres is the handwriting '22 L R' is on the left rear and '21 L F' on the front left

If PD counters Forza's Ford GT 2016 with a Chiron, then PD win instantlyI'd love to see the Chiron as the next cover car for GT.
I'm really looking forward to this VGT , haven't been this excited for GT in a long time.
Bugatti would definitely be a more interesting front cover. Since they've been really hesitant with video games in the past, it will be like taming a shrewIf PD counters Forza's Ford GT 2016 with a Chiron, then PD win instantly
Exactly my point. A cheap way out from not having a display in the cockpit.That would be distracting if so.
Edit: Not to mention there's no helmet cam...
No. What matters is the view i like most, the view that is of this age, i'e fully modeled cockpits. Not having them is just lazy. When im in a Ferrari i want to see im in a Ferrari and not that im just in my room in front of a tv that is suposed to be a windshield which in fact doesnt apear to be a windshield but rather a camara outside of the car thus not giving me any sense of imersion like the cockpit view does as i have sat in many cockpits but have never driven a car from the bumper.Im just trying to make you guys see the light You guys should realise that the physical cockpit + physical wheel is what matters, the virtual one doesn't. The cockpit is the real one, the TV screen is the windshield of the car
Well that Bugatti looks very neat but the Hyundai is looking more interesting IMO. The only thing we hope for is that the Hyundai is not a 2000 HP speed demon.
that's some hardcore physics and mathIn terms of top speed 2000 BHP is only twice as much as 250 BHP, because in order to double the speed you need to multiply power by 8. The increase in acceleration is far more dramatic than the increase in top speed.
Ignoring other forces, top speed is when the force of traction pushing the car forwards is equal to the force of aerodynamic drag acting in the opposite direction, when Ft = Fd.
Ft = force of traction
Fd = force of drag
The force of drag increases with velocity square:
Fd = x*v^2
v = velocity (meters / second)x = 0.5*air density*drag area (air density in kg/m^3, drag area in square meters)
Force of traction depends on wheel torque and the amount of friction between the tyre and the road. To simplify we can use a tyre with no slip, i.e. all the wheel torque gets converted to traction and no torque is lost. Since we're dealing with power and not with force, we need to convert the force of traction to power:
F = p / v
F = force (Newton)
p = power (Watt)
So in the equation we substitute Ft with p / v and Fd with x*v^2:
Ft = Fd becomes p / v = x*v^2
Now we can multiply both sides with v to find that the power needed to reach velocity v increases with the cube of v:
p = x*v^3
Feeding the equation with values, here is the power required* to reach some speeds with a typical car (drag area = 0.6 m^2, air density = 1.225 kg/m^3):
50 km/h: 1.34 BHP
100 km/h: 10.71 BHP
200 km/h: 85.68 BHP
300 km/h: 289.16 BHP
350 km/h: 459.17 BHP
400 km/h: 685.40 BHP
450 km/h: 975.90 BHP
500 km/h: 1338.68 BHP
550 km/h: 1781.78 BHP
600 km/h: 2313.24 BHP
(*Plus the power required to overcome rolling resistance, friction and other forces that acts in the negative vector.)
So even a small increase in speed requires a big boost of power. The difference in top speed between a 1000 BHP car and a 2000 BHP car may just be 100 to 120 km/h.

Nah, James May would be able to do only calculations up to 50kmh@eran0004 Are you James May?
I don't think it's something to worry about, we can look at the Peugeot VGT which uses a similar set up to the Veyron but weight 1000 KG less, and that only breaches 700 PP after an oil change.Curiosity got the better of me, so I cranked up GT6 to check out some numbers.
Here's some comparisons of cars mentioned in this thread.
FFX : PP - 629 : BHP - 788 : Weight - 1155
Zonda R: PP - 630 : BHP - 739 : Weight - 1070
Veyron: PP - 639 : BHP - 987 : Weight - 1888
GT by Citreon: PP - 673 : BHP - 778 : Weight - 1400
Looking at the base Veyron figures, I'm a little worried.
While shaving off 400 or 500 kgs. to match the Citreon seems somewhat reasonable considering it's clearly a track race-car (let's even call it substantially less than that), my concern is the BHP output vs PP.
As much as I hope for this VGT to be in some sort of competitive PP range, I fear it will be beyond too many other cars.
Can anyone see a reason why they would de-tune the 16:4 engine to the point where it's not excessively beyond other cars?
