Tires and Gas

[Superhero Wally]

This one of my biggest beefs with the series. The fuel consumption and tire wear occur way to fast. So how about a more realistic model of each. I can't remember for certain but i do believe at the le mans 24hr a car has to complete an x number of laps before it can even pit for the first time (i want to say it's 15 or 20 laps, but i'm not positive). Then there are F1's which must complete qualifying and the race on set of single tires.

The tyre wear does, the fuel consumption, not sure, real car's when their being driven hard like that don't go far on a tank. My Bora can be economical, but if I tyre driving it fast, the fuel just goes. My 306 is simply, economical, it can't be driven fast .

At LeMans I think cars usually do 9 or 10 laps per change, F1 car's get around 25 laps depending on the track, the tyres in GT do wear too fast.

I was about to welcome you to GTP since I didn't recognise you, then I noticed you've been here nearly as long as me .

The Bentley Speed 8 managed 4.2mpg at Le Mans, I'm told.

 

[Dave A]

Does anyone know what the car's average in GT4, roughly?

 

[Superhero Wally]

Well 80 liters of fuel is roughly 21 US gallons.
So if the Speed 8 gets 4.2mpg then the Speed 8 will average roughly 88 miles per tank so 10 laps at Le Sarthe, which i believe is about the equivalent in GT4, but i am not positive,so if some one could experiment with that, that would be great. So that seems appropriate.

Right now i'm running the nurb 24hr in the Suzuki GSXR/4, refueling every 14 laps with about 1.5 gallons left in the tank. So I am averaging roughly 9.3 miles per gallon. But this is a car that weighs 1300lbs and has a 1200cc inline 4 making 190hp. So thats only 2.2 times the mileage of the Bentley Speed 8, a car that weighs 700lbs more, has twice the number of cylinders, 3 times the displacement, and 3 times the power. Granted the layout of the tracks are very different and this will have an effect on fuel usage as well. So the LMP's seem well represented for their fuel consumption, but that 9.3 for the Suzuki just seems way too low for such a vehicle to me.

I guess more experimenting is needed, but for now back to the Nurb24.

 

[Eric.]

We don't know that the 80 units of fuel displayed are really in liters though, considering every car has the same size tank.

 

[Dave A]

I'd presume it is and that for the sake of simplicity, PD gave every car the same tank.

One thing I've thought would be interesting is instead of paying tens of thousands for tires for life, what about paying a fraction of that for a set of X number of tires? Especially for one-off races and series, there have been cars that I needed good tires to win a race, but didn't want to pay $20,000 for them since I wouldn't race the car much afterwards, anyway.

Super soft tires: they're great for qualifying, but that's about it, few races can be handled on their short life span (the ones that do are dinky B licence ones usually, that yeild you like $7500 total) and they cost what, $40K? They can't be used hardly anywhere, and they cost a fortune! I'd love to pay maybe a couple grand for a small set of them, and buy them as I need them. Same goes with other tires, I only need series worth, and then maybe I'll need another type for that car. So instead of paying out the nose for an infinite supply, why not buy tires as you need them, small sets for small money? It would also be more like real life, racers don't get lifetime supplies for a set price.

Now, some cars, I race a lot, and maybe use only one type of tire, and buying by need is much more expensive in the long run. So what about the option to either by a lifetime supply of mediums for around $20K, or a set of, say, 40 tires (10 pits-worth) for a $2000? Just an idea.

Edit: And yes, I've always felt tires wore WAY too fast.

 

[NismoR34Ztune]

i was satisfied the way it was really.....

 

[SirBerra]

To get better fuel consumption, use numerically smaller gearing, shift way before the red line and never let the shift light go on when downshifting. If you can go around any complete course in 5th gear while making decent time, you'll save a fair amount of fuel. It's also a good way to decrease tire wear.

 

[the Interceptor]

Well yes, the tires do wear much too fast, but there's some logic behind that. Most of the races are only a few laps long. What would be the point of tire wear if it only matters in races of 30 or 40 laps?
I'd love to see realistic wear in GT5 as well, but I understand why they did it like this in the previous GTs.

[3-Wheel Drive]

Yes, but I've never liked having to pit in a race thats 15 laps or fewer. The smaller races are mean to be quick, why bog them down with unnecessary pit stops?

 

[Mt. Lynx]

I agree with most things said here, and I have done a comparison on LMP/GTP/Group C cars for endurance racing, found in my sig. The Speed 8 does 9 laps per stint, but in most cases the stints will be determined by the tyres.
I feel that even R1 tyres have way to much grip and way to short life. Maybe equivalent to a soft compound racetyre or so IRL.

 

[GM]

The tyre life is rubbish on GT4, in F1 on soft tires the cars can go around 20 laps.
With a Nissan R92 on Grand Valley Speedway with Racing Super Hards on the back and Racing Hards on the front, the tires go red after 13/14 laps.

 

[Dave A]

In F1 there's only 2 dry weather tyre's and teams use one or the other, they don't have a choice of soft, medium and hard compounds they have a choice of slick, intermediate and wet compounds, that's it. They're probably not comparable to the soft tyre's in GT4, because there's only the one compoud to chose from they'll be a compound chosen to provide the best balance of performance and wear so you can get through races with 2 or 3 stops and no more. They used to have special qualifying tyre's in some motorsports, but they stopped using thoes a good while ago, but they wouldn't last more than 2-3 laps on an average track, they'd provide bloody fast lap times though.

But yeah, overall the tyre's in GT4 do wear out a lot faster than they should do, the super softs arn't too bad, they should have a life span of only 3-5 laps depending on the track, but the difference between the super soft tyre's and the super hard tyre's should be a lot bigger, super hards should lasst 25-30 laps on a track like Grand Valley in a car with traction control on minimising wheelspin.
