Bet this is some kind of weird ass corporate deal between PD and Honda :lol:

Its so forward, the quote, its not like "purchasing a car" and its so damn specific, Honda FIT and all, who the hell wants one of those..?

Thankfully I'll forget about this thing as soon as the N events are over. I kinda like it though, depite it being an FF car and all.
 
It is the most "realistic" sound in the game so far. It sounds like a "super-turbo-charged" F1 car...but it has the top rev sound, and the intake sound as well.
But in the most unrealistic car of all...oh PD...oh you...:lol:
If that isn't the epitomy of irony, I don't know what is:grumpy: Only PD...only PD...👎

They should have modelled the CRX and given us that, a car from a time when Honda was lame but not as lame as it is here in 2013. But a Honda Fit? gah, why so uncool, its even worse the CRZ, except the Fit actually sold better then the CRZ of which Honda sold none because its crap and looks like a piece of chicken with snow on it

Daytona at night <3

Seriously... there is nothing more super ultra epic than one big circular spherical speed dome of magic super sloth awesomeness. I love Daytona, partly because I can't drive on tracks and like dirty racing but still... dayum! I'm getting ideas for a race series, which I'm totally and guaranteeably capable of running, ovals are amazing.
 
Veyron: 1800 kg
Viper: 1200 kg

That should mean something when it comes to top speed.
No, the car's weight is negligible when it comes to top speed. I'll calculate it for you to get an idea (this can get tedious, sorry for that.. :yuck:. In that case, just read the bold part and ignore the rest of my message):

When simplified, the car reaches its top speed when the power is equal to the forces holding it back. There are two types: drag from the air in the atmosphere (1) and drag from the friction of the tyres rubbing against the asphalt, called rolling resistance (2).

The two formulas for those are:
0.5 rho v² C_d A (1)
mu m g (2)

In which the symbols are (with typical numbers)
rho = air density in [kg/m³], 1.2 @ 20 degrees Celsius
v = speed of the car in [m/s], 100 ( = 360 km/h = 224 mph)
C_d = drag coefficient [-], 0.36 (Viper)
A = frontal area of the car [m²], 2 (Viper)
mu = dynamic friction coefficient [-], 0.015 (worst measured for rubber against asphalt according to Wikipedia)
m = mass [kg], 1200 kg (Viper)
g = gravitational force [m/s²], 10 (earth's gravity)

This results in these number for the Viper:
- Air resistance: (0.5)(1.2)(100)²(0.36)(2) = 4320 N
- Rolling resistance: (0.015)(1200)(10) = 180 N
Total: 4500 N

Note that air resistance is more than 20 times as large as the rolling resistance (i.e.: mass makes very little difference to the top speed)

If the car weighed 600 kg more, the total drag would be 4590 N, only 2% more.
In other words, at top speed, mass makes almost no difference and it's air resistance that is the main limiting factor, which is only determined by a car's shape and dimensions.
 
They've dropped the Ferrari F1 sound and seemed to have opted for a more turbo V6 sound, which is appropriate considering its supposedly powered by a turbo charged V6.



Pretty sure that's there as part of the track license, something EA does not have control over.
That's the same sound as in the gt5 opening movie right at the end! Listen to it and watch the video

Indeed. I concur ;)
 
Err, it actually is. It took 2,000Hp from M2K's Ford GT to just touch 278Mph & the amount of modifications & setup that car needed to do so is more than likely beyond what GT will offer. There is another Ford GT owner claiming he will attempt to hit 300Mph, but his GT will be running well over 2,100Hp & that's if the engine can even sustain the power long enough or if the car is stable enough to do so.

Fact is, Gran Turismo has always exaggerated the capabilities of some cars when modified to a certain power level.
That disproves nothing I said. ~1400hp cars can do around 240-250mph in a mile irl, so hitting 300mph on route x isn't unreasonable.

The interior shadows got downgraded so much. :( Thanks a bunch to the complainers about jaggy high-res shadows. Now we got low-res flickering ones.
 
O guys, I've realized that we can actually calculate whether the top speed of that Viper would be realistic or not from the video below (following up to my post somewhere up here in this thread proving that the mass of the car doesn't really matter and that only air resistance is the main limiting factor of a car's top speed)



In the video the tuned Viper has 1371 hp and reaches almost 500 km/h, this in SI units are respectively
1022.4 kW of power and a speed of 139 m/s.

The stock Viper corresponds with the following power and top speed:
480 kW and 92 m/s (640 hp and 206 mph)

Now there is this nice formula based on air resistance to calculate what top speed is achievable just by increasing the power of the same car:

power = constant * (car speed)³
For the Viper, the 'constant' has a value of 480/(92^3) = approx. 0.000616

(constant = 1/2*air density*drag coefficient*frontal area, just like in the formula to calculate the air resistance. As the 'constant' is calculated from the numbers of the stock car, the big advantage is it is not needed to accurately know the particular air density, drag coefficient or frontal area. All we know is that the product of these three paramaters corresponds to the Viper and that's enough to calculate a new top speed, when the power is the only parameter that changes)

So with 1371 hp, in theory the Viper should reach a top speed of:
(1022.4 / (480/(92^3)) )^(1/3) = 118.4 m/s = 426 km/h = 265 mph.

The number of almost 500 km/h is therefore very unrealistic, which is a shame as PD did advertise the new aerodynamics model so explicitely.

(in order to reach 500 km/h like it does in the video, the Viper would need 2215 hp, so @McLaren is totally right in this post)
