If you had to choose a car for a very tight twisty track what would you go for?

A small lightweight turbo FWD with LSD, a large engines V8 RWD muscle car? What about an AWD car like the Skyline GTR? Where does engine power and weight come into the handling equation?
 
I can only comment on what I have experienced so this is just an opinion. I personally would go for nasp FWD with LSD and keep it in the power band. If you had such a tight twisty track you could well just be on the power with a turbocharged car and end up going off the track or stuffing it in the bank, have seen this first-hand. I was racing against an RS Turbo many years ago and he flew past me on the straight and as soon as the corner came up he couldn't stop as was practically on full power and no matter how good the anchors were he couldn't stop to enter the corner. With RWD they had to set the car up to 'drift' around the corner, feathering the throttle to avoid spinning and doing so the FWD could nip up on the inside as long as they didn't put too much into the corner and end up understeering. Cannot comment on AWD as not raced these as back then they were not allowed in our classes. I have raced both RWD and FWD and I must admit to preferring FWD. However RWD is a crowd pleaser!
 
If the question is ONLY for a small twisty track then first you need a small car . Or more exactly one that isn't big.

I think that the examples in the first reply point to bad driving not bad handling. If a driver can't brake for a corner that's his fault not the cars. He is just braking too late.

As for the choice of fwd or rwd I would simply point out they don't make many (or any ?) fwd racing cars that should tell you something .

Personally I prefer AWD although it's advantages do diminish on tighter tracks and on less powerful cars. A trick diff will only do so much on a fwd car
 
The chap that ended up going off the track with the turbo car had the wrong car for the track in question, short straights and tight corners. He literally couldn't stop it once the turbo kicked in and eventually gave up and went nasp. There was no run off and was a banked corner so it was beaten up after a few laps.

With regards the comment on they don't make fwd race cars are you referring to a particular type of race car or design? Maybe I am missing the point but I am thinking of BTCC, MG Cockshoot Cup (both rwd and fwd), Clios and any other type of popular racing series. When you get to the likes of supersaloons/sportcars etc then yes they are rwd/awd as fwd can only take and use so much power.

How did he manage to go NA (unless he had a different car ) you cant just take a turbo off a car thats been set up for one.

Im still amused you think it was even partially the cars fault .
Yes in this instance the car may have been a handful on that track although I personally cant see an escort turbo being that bad.
Anyway that wasnt the cause of the problem - a fast car cannot cause braking too late thats driver error every time.
Only the driver controls the speed approaching a corner usually by taking his foot off of the loud pedal and putting it on the slow pedal. If the car is lightning quick brake earlier or use less of the lod pedal.

As to a racing car
In my mind a racing car is just that - those made exclusiely for racing . And these will always be the fastest round the tracks even say lydden hill which was the topic.
Have a check - the outright fastest lap for virtually every UK circuit is almost always a rwd racing car mind you so it should be

My point was that if you make a full race car from scratch (any formula) you dont build a fwd car.

But if you are going to change to popular road cars of course you will get a different answer

If the question is whats the best road car in sensible budget round a small twisty circuit then it probably is FWD unless you want to count the caterhams
 
I think part of the issue there is that cars are sometimes just not set up properly, the braking and suspension are not matched to the cars weight and performance for example.

Turbo boost points are also critical. High power late boost cars can be a pig to drive but on some tracks and competitions that is exactly what you need.

I don't think we should limit ourselves to road cars. In a competition setting there are rarely limits and constraints and it will allow us to have a discussion about the ideal setup for this type of track. I think discussions about tracks with long straights and drag races have merits but this one is showing we approach it in different ways and have differing preferences.
 
as hdi said In principle the fastest car round bends should be the one with the most lateral grip.

Leaving proportions ,tyres and weight aside most grip has to be awd or 4wd.

In practice it will actually be the car that is set up best which is why it will be a racing car cos they are set up without compromise or worry about cost (unlike a road car)
They are almost always RWD because 4/AWD is often not allowed , possibly for that very reason
 
I'd quite like to see an Original UR Quattro go up against the Lancia. I'm sure it would be a close thing!
 
It will be interesting to see. My boss had the UR Quattro back in the 90's and having driven it I was very surprised at the pin sharp handling. Not driven an Integrale though.

They always did well on the rally circuit - up until the Lancia integrales came along in 1988 I suppose so you could be right Sleeper!

What modern cars would be in the running against these classics then?

A lot of a cars handling is down to the skill of the driver, in the right hands though, short wheel base cars tend to do better on twisty tracks.
 
A good driver in a well set up FWD car can set very fast times using a combination of left foot braking and lift off oversteer to dial out inherent understeer characteristics of a FWD .
Short wheel base cars can be more twitchy.
