The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute (88 feet per second).
The Highlander is still (likely unintentionally) the speed demon of mainstream three-row CUVs. Its 112-foot braking distance from 60 mph improves on 122 feet. It circled the figure eight in 27.8 seconds at 0.62 average g, meaning it made it all the way around without rolling over.
