I thought they are trying to induce a slide so they cn use the gad pedal to steer around the turn, or maybe the car is just getting understeer.

Re: Rally car steering question.... (Silly_me)
A rally car does not follow a traditional racing line. The driver sets the car up with an initial input and then steers the car with the throttle using the momentum of the car to do the work. You will see a little steering input during the exit of the corner but not much. You will even notice this in a street car like an Audi with quattro on snow or dirt. Very little steering input is needed once the car drifting, it's all done with the throttle. The steering is just used to keep the front wheels pointed to the exit of the corner.

Perhaps. It's difficult from a cockpit pov to see if he's drifting the car around a curve.
Aren't most of these new rally cars FWD? I would think that it would take a bit more steering input to bring on a drift.

AFAIK, the 'Scandinavian flick' is all about getting the car and front wheels pointing in the right direction on the exit of the corner, so that you can put the power down earlier.
They always used to say that if you weren't looking out of the rear side window in a '70s Ford Escort, you weren't trying

The first flick is probably to get the car to start drifting.[HR][/HR]
This is what I was thinking. A tyre can only do 100%. 50% steering and 50% acceleration etc. So I'm thinking multiple quick corrections allows for more tyre being used to power rahter than for steering.
Re: Rally car steering question.... (Silly_me)
they also start to turn the car for the NEXT turn while still in the current one, so that they can power directly out of the exit. So if they know that a right is coming up in 50 meters, they will turn the car hard to get it drifting at an angle, so that they can simply (for them) use the power at all 4 wheels to pull them through so that they are pointing straight ahead after the bend.
That's the beauty of pace notes and knowing exactly where the road goes. You can set up before you even get there.

Re: Rally car steering question.... (Silly_me)
WRC and gr. A regulations: max. 2000 cm3, four wheel drive and turbo, max. 300 hp
Nowadays every top rally car is built to the WRC regulations, now even the Lancer/Carisma.
Difference between gr. A and WRC regulations: The basis of a WRC car can be a normal FWD car with no turbo. You can add a turbo and a different basis engine (as long as it's from inside the factory) from another model and you can add AWD system, even though the production model doesn't have one. There are certain production numbers that the basic car has to be produced during a certain time lapse. In gr. A regulations you have to produce certain amount of the actual classification model. Good examples are Mitsu Evo's, Lancia Delta Integrales, Escort Cosworths, Audi quattros, Toyota Celica GT-four's, etc... The classification model has to have the same basis engine, as well as turbo and AWD. Mitsubishi made a WRC car out of the new Evo VII, although it would've filled gr. A regulations. Within the WRC regulations they were allowed to modify the rear wheel suspension more, that's why they follow the WRC regulations now too.
Gr. N regulations: basically like gr. A, but less power output and less suspension, brake, etc. modifications.
F2 regulations: FWD, max. 2000 cc, no turbo and max. 250 hp (IF I'm not totally wrong)
Super 1600 regulations: max. 1600 cc, FWD, etc.

Re: Rally car steering question.... (Son of a B...5er!)
While the top level cars are AWD, a large number of rally cars in leauges other than WRC are FWD. Many British Rally Championship cars are, as are many in SCCA ProRally and other rallies around the world. In many rallies, two-wheel drive cars are in a different class than AWD cars, so they aren't competing against them directly.

edit ---> in case you missed the sarcasm, that was a "no". AFAIK, you can also buy a turbo AWD Citroen Xsara, Hyundai Accent, Skoda Octavia, or Peugeot 206 only in your dreams.
