“Once we determined to provide the brand new development in Silverstone [earlier this year], it’s only a new materials that’s, with the identical weight, extra resistant.

“So, our analysis and growth on new supplies – we have now a devoted division for strengthened supplies and compounds – are all the time taking a look at enhancing the resistance of the fabric, maintaining the burden as little as doable.
