He also points out that, although he shed about 20 kph for the kink, he gained all this speed back accelerating between the kink and the right-hand turn before having to brake again. While true, I think that with less than half the power, it would have been a lot harder for me to claw back any speed I shed going into the kink. I think it's reasonable to approach the kink slightly differently depending on the type of car being driven.
When I see Ryan at the top of the PAX scales in an ES Miata I'll retract my previous comments and agree with Stephen that the Miata is the car to have, until then Im not convinced.

That said, I do believe a Miata would have made the speed back too, see below.In the end, I do not accept that the correct line changes drastically from car to car. When I say line really I mean strategy...maybe you won't end up on the exact some line car to car but the what you are trying to do doesn't change. Even with little power you need to maximize the time on the throttle. Even with lots of power you can't drive triangles everywhere. I chose my line because it was the shortest distance from the end of the slalom to the finish lights. I would have attempted to do the exact same thing in a Miata. Lets not just look at power when deciding what to do in a Miata or 'low powered' car....because there is no such thing as a low powered and big and heavy and competitive autocross car. In an NB Miata that is some 1,000 pounds(!) lighter than my M2 I would not have had to slow nearly as much to make the left turn out of the slalom while being on the same line. Therefore would have had less to 'make up' on throttle. I would still have been on the shortest path to the finish and spent less time in the slow 180 degree turn.It's possible I'm completely off the mark but I haven't heard a thing so far to change my mind.
I have a simulator where I can set up autox courses of my choice and run them with cars of my choice. If I have enough time (probably this winter), I will set up something like that sequence and go at it repeatedly. Or if anyone else wants to have a go, let me know and we can make an evening of the exercise.
That's because the Miata wouldn't have been going as fast.

The Miata may be acceleration limited, but those increasing offsets in the slalom would allow a lighter car to go much faster. The Miata should be the one needing extra braking.

Ryan's car will get up to maximum speed in that slalom long before me. However, due to his car's weight and width, that maximum speed will be slower than the Miata's.
