Winter Test/System Comparison 2000 – Winter Tyres are Indispensable

It has almost become a tradition by now: Once a year the German subsidiary of Japanese car manufacturer Mazda invites the trade press to a winter test/system comparison. The journalists attending in Saas Fee in the Swiss canton of Valais were asked to perform a number of driving tests under various conditions. The necessary winter tyres and know-how were provided by workshop partner Continental, and the computer-aided evaluation of the results of these practical tests was handled by representatives from TÜV Rheinland/Berlin-Brandenburg.

The most important part of the workshop results was: On snow and ice winter tyres are absolutely indispensable! The tendencies worked out in theory were generally confirmed but, contrary to expectation, no significant difference in handling was discernible between front and rear drive. Similarly, the two front-driven vehicles – whether on TCS or ESP – ended up with nearly the same result. But brake tests with ABS did demonstrate the expected differences in the performance of winter and summer tyres, with the average traction quotient of 88 p.

c. (winter tyre = 100 p.c.

) for a front-driven summer tyre, however, considerably higher than the 76 p.c. estimated by the group.
