Any car that has an after market turbo will accelerate when you turn, even if you don't have the gas down.

If you are driving in a straight line and let off the gas, the car slows down.. if you start to turn while slowing down or just turning while not depressing the gas, the car will speed up, and on AT will even shift up to the next gear even though I'm still not pressing the gas... it's very annoying. What's causing this?

Its the ASM. Turn it to zero in driver aid settings and it will stop
 
yeah,i couldnt figure that out for a while and i was buggin the crap out of me. having to brake extra for the turns because the throttle wouldnt cut out completely but i was the oversteer ASM setting :crazy:

This is also the case when you hold the e-brake while turning, the car accelerates for some odd reason.
 
Yeah this happens with my R32...I thought it was because I bought it used and it was a defect. Now I know :lol:
 
Also, the limited slip setting for de-acceleration is set to high.
 
Cars grip best when accelerating or braking.

That's why they tell you, you should always be doing one or the other.

The game's automatic drivers assist thing just compensates for your incompitence.

No offense :dopey:

How do you get more grip when braking? Won't you slide more easily?

soft tires, jack up the brake controller pretty high and set the decel on the lsd very high... im guessing that will work pretty well.
 
That's what you get when you play with Driving Aids on lol...I hate that stuff
 
This happened to me too when doing the s licence with the Audi R8 at infineon raceway. I would let off the gas for a corner and the thing accelerates and throws me off track. Very frustraiting. I hate driving aids especially on really fast race cars. It makes it hard to drive smoothly and you can't disable them for the licences. :mad:
 
Cars don't necessarily grip more while accelerating or braking. "They" tell you to do one or the other because for the most part that is how to get around a track faster. Tires only have so much grip (100%). If you are using 90% for braking, you only have 10% left for cornering. That being said, mild brake pressure can increase the amount of grip available to the front wheels (trail braking) by shifting weight foreward, and acceleration can shift weight (and therefore grip) to the rear wheels. That is why dragsters are rwd.


As far as the original question in this thread, I always thought it was the turbo staying spooled up w/o a wastegate.
 
It's hard to drive a car without the driver's aid atleast turned somewhat on, but I think I'm gonna have to just get better at it. They really do mess with you too much in this game. It's not realistic for any type of traction control to accelerate a vehicle (maybe some throttle in some conditions, but doubtful it would be acceleration, probably maintain speed).
 
I was just about to ask this but found out what the problem was. I was using my Supra 97 RZ and the turbo just spoiled up in the center of the turn! And i started to "power slide" or dift the turn. It was fun!

Wth used?! Who in the right mind would trade it in at all? Such an awesome game.. haha..

I think he meant his REAL life car did this and he thought it was because he had bought it used....
:)
 
Isn't it a fact that due to physical dynamics a car will accelerate during cornering (if maintaining the same velocity through the turn) as forward motion and sideway force adds up to acceleration?
 
That just confuses non-physicians! lol

all cars accelerate round corners!

in physics any change in velocity(being a vector has two components, magnitude and direction) will give acceleration, therefore changing direction at constant speed is accelerating.
 
I'm not convinced that one should always be either accelerating or braking to use more grip. If you watch the F1 driver Kimi Raikkonen, his style is distinct as he often spends a large amount of time in the middle of the corner not accelerating *or* braking, but just steering the car.

And just look what happens... He doesn't get to the finish line like ever. And if he gets there, he comes in last. He's style, I think, is the reason why the car kept falling apart in every race last year. Formulas are meant to be pushed to the limits, but he doesn't use enough gas when he's driving.

I don't know where you got that idea.LOL.If you ever saw the Daytona 500 you'd know that those boys keep the throttle pinned to the mat all the way around the track and in the turns they "scrub off speed" as they say.That's caused by the momentum of the car trying to keep the car going straight and the front wheels trying to make the car change direction.The front wheels are generating friction which = drag which = loss of speed,not acceleration.The farther you turn the wheels the more drag is generated the more speed you loose.When the wheels are straightened the tires roll free allowing the car to accelerate back up to speed.

Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. "After all," they might say, "if I were driving a car in a circle at a constant speed of 20 mi/hr, then the speed is not decreasing or increasing; therefore there must not be an acceleration." At the heat of this common student misconception is the wrong belief that acceleration has to do with speed and not with velocity. But the fact is that an accelerating object is an object which is changing its velocity. And since velocity is a vector which has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity.

Touche. Like it or not it is the truth that cars are accelerating around corners even IF they are braking. There are two components to acceleration: velocity and direction, its a mathematical principle.
 
I think the cars momentum increases when it's going thru a corner, but the actual speed decreases. Imagine the cars speed increasin while going thru a corner, means you would go faster and faster just by turnin the wheel :p
 
is this all from the acme looneyversity department of physics or something?

I believe that mathematically using vectors and stuff they will accelerate in some manner, negatively or positively. sure some brain box knows but i know for a fact my real life car does not increase in speed at the wheels in a corner, that's just lunacy-first thing i remember from driving lessons many years ago was my instructor telling me to press the accelerator a bit more to maintain speed.

My cars got a speedo and it goes DOWN when turning!

wtf???.....so its his fault if the cars engine blows up because of a mechanical problem??....and he certanly DID NOT come last in those events where he made to the end.....

you're just full of ****.....
 
surely that method of driving is inefficient? As in, say one drives into a corner on gt3 or 4 or any racing game really, u brake, you steer, you accelerate. Ideally, you would brake to a speed whereby you can take the corner, and then accelerate the whole way out of the corner to maximise your exit speed. If you don't quite brake enough, you then lift off and go around the coner off the throttle whilst the car gently slows down (as raikkonen may be doing) then it would be better for him to have braked harder, scrubbing off the extra speed in a fraction of a second as opposed to over half a second while he has lifted off, then he can get straight back on the power.

Basically, the 'ideal' way to get around a track in the fastest possible time is to be accelerating constantly, and so you want to minimise the time where you arent accelerating, i.e decellerating, so lifting off and coasting takes longer than braking, and so is bad.

Thats my two cents on the raikkonen discussion.

As for accelerating when you turn, that must be ASM or something similar, because, although yes on a technicality, the car is accelerating(its sideways velocity is increasing and so it is accelerating), the speedo does not measure sideways velocity, and so i would agree that you should stop using these girly man driver aids(if you can turn them off,i appreciate this may be a complaint you had in a license test) and learn to control the car yourself, as ASM slows you down, without a doubt.
 
Well, as we just discussed and studied in class Mass, Acceleration, Momentum, Newton Laws, and other crap. Like VGtC said, cars are always accelerating in a turn. Anytime Celocity is changing, you are accelerating, braking too. Actually, I don't know. carry on! :dunce:

don't think you studied it too well. Id ask for a new teacher, as he/she clearly didnt explain it properly! As they say, "It's quite simple really," and any confusion has merely been caused by someone being a bit picky and using the fact that if you're driving north and you brake, you may be considered to be accelerating south also. So yes when you turn, you are accelrating in the direction you have turned, as your velocity in that direction has increased, however your velocity in your original direction has most probably dropped.
