This car is designed as a hillclimb car. The goal is to have a light and extremely responsive but forgiving car with a high amount of crashworthiness. It was first run with a stock Hayabusa engine and has since been upgraded with a custom-built turbocharger setup. The engine package is sweet to drive, it has a real wide and flat torque curve with the turbo coming on full boost by 3500 rpm and holding the boost till the 11,000 redline.
So far the car has been run without any wings. Even so, it corners at 1.65G, brakes at 1.7G, with 1.1G

acceleration in third and 0.86G in sixth. It pulls 0-60 in about 2.8 seconds. No quarter mile times yet.

I can't wait to see what it does with wings! The power band is so wide one has a choice of three gears to use in most situations.
