In the tests, which were filmed, the two cars were used to highlight the differences in braking distance and cornering performance between the standard-fitment summer tyres and Michelin’s Primacy Alpin winter tyres.

The braking test was done from 15mph to zero and the results showed that the car fitted with the winter tyres stopped in 7.01m compared to the summer tyre-shod car’s 9.75m: a difference of 40%. 

The cornering test also highlighted big differences as the cars were driven through a corner made up of cones at the same speed. The car on summer tyres suffered from high levels of understeer as grip was lost and it could not complete the manoeuvre. In comparison, the car fitted with winter tyres drove safely around the corner.
