To get some data to support the craziness of the ETC rules, I went out in a production car and collected some data of basic parameters, including engine RPM, vehicle speed, longitudinal acceleration (measured), brake torque (calculated from pressure), throttle angle, and pedal voltage. This particular car was an automatic, naturally aspirated, all wheel drive.

I found that, while I was able to get the car to -1G for over 0.5s (and -0.8g for approximately a second), at roughly 80% (gas) pedal input, the engine output torque target continued to follow the pedal in all cases (NO reduction in engine torque, at 1G deceleration and 80% pedal). The throttle remains approximately WOT, without any other torque reactions (let alone closing to the 9deg/10% specified in the FSAE rules). Power enrichment is active for much of this, as well.

I'm also beginning to capture stuff like this on my daily driver car (turbo mtx), showing how much pedal input is needed while on the brake (not surprisingly, it's a lot).

How do they seriously expect FSAE cars to downshift with 10% throttle? What about turbo cars? Why can't the driver stand on both pedals in preparation of a launch in accel (or any other event, for that matter)?
