test.

It was a track test. However, the track is short with lots of corners, and
you can't achieve speeds much above road legal ones for long periods. It
puts no more stress on a car than spirited driving over a hilly and twisty
quiet country road. Such as you can easily find in parts of Wales and
Scotland.

Normal road use and testing doesn't put anywhere near as much
stress on cars as TG do,

Not much point in advertising a sports car which has to be treated gently.

However, it's worth remembering the original Autocar road test of the
Prius. Over 600 miles of testing on all sorts of normal roads, its average
mpg was in the low 20s. Toyota weren't happy.
