How to apex a series of S turns

Doing a lot of karting and no matter how fast I tried to arc in to the turn from the outside while carying speed, the fastest time was to slow down early and hug the inside edge through the entire turn.
That said I didnt set any records - but it was my fastest time and faster than most people by quite a bit.

completely two different approach and driving style needs for the two car. One is a heavy tall AWD car the other is small very light rwd kart.
Also if go-karts have a body roll that means something really bad, not so much with an evo.

OP line is fastest if the course is flat and you're trying to maximize exit speed. The shortest line is NOT fastest. The shortest line on a 180 degree corner would be to hug the inside, but the car wastes more traction to follow a tighter radius. Therefore, a late apex, sacrificing apex speed for corner exit is ideal. Talk to a professional slalom driver (probably in the UK) and he will tell you the same thing. You obviously don't want to park it, and every car will be different, but my knowledge of the Evo, both the 8 an the 10, would lead me to believe that it would not like to make a tight radius required for the "shortest line" and would benefit from getting to power in a straight line.

I too use robevo's line for S turns, don't do much rallying but thats how I was taught and the physics of it have always felt right for me. Regarding the Kart comment, I used to race karts at the amateur level and you can't really compare driving lines of karts and something like an evo. Two different beasts entirely.

Eh, I'm not buying it. Physics says the shortest line doesn't win, the highest average speed wins. You'll have to slow the car more to make the tight radii. I think the image itself leaves some question as to what exactly would be a real-world scenario, but I'd almost always try to park the car to power out, especially in something like an Evo that doesn't exactly like to change direction.
The point and shoot thing is sacrificing apex speed for traction on power-down. Racing a Camaro for a living, trust me, I know what point and shoot is all about... they don't exactly have great apex speed and, like the Evo, require some time to change direction.

Interesting thread. I ponder these things myself quite often.
In my Evo I didn't notice a huge difference taking various lines and paths... A second here or there wasn't as noticable. But taking the same turns in my 02 Escape with 200hp shows the errors much more obviously. Now we're talking an obvious 3-5 second difference between the lines.
I know it probably doesn't help to mention this, but have you tried taking a less capable vehicle through this course? The line that lets a top heavy SUV hold the most speed is most likely very close if not the same line that the Evo should take.
The Evo hides many mistakes a less forgiving vehicle shows..... Now don't think I'm telling you that it's identical because it's not. But it helps you notice things you may miss in the Evo.

looking at that ms paint drawing, lime rock almost has a very similar series of turns coming off the main straight. there at least, i found it fastest for me to single apex the sweeper, late apex the first s to get a better line through the final s onto the back straight.

You know what this reminds me of? The Evo X at Infineon's esses. I've had hundreds of laps through that complex in that car and there is a combination of line types CLOSE to Rob Evo's, but always late, getting the direction change done early. The only exception is the final corner that has a hill in it which will hold you to the inside, allowing an earlier apex.

You always want to transition from your outside to your inside of a turn, lining yourself up in a straight line for acceleration whenever possible. lateral movement is time lost.
