His average acceleration rate was 103mph/sec^2, or 151ft/sec^2, or 4.69g's average.
This is slightly better acceleration than a 2500lbs car with 10,000hp and perfect traction.
It's always mind blowing to see how much traction is attainable with good tire compounds and well designed chassis. This little car can push against flat asphalt harder than 4.6times it own weight. That's some amazing tire technology!
