The special anniversary parade, dubbed 911 x 911, to mark 50 years of the Porsche 911 at this summer’s Silverstone Classic (26-28 July) has proven so popular that it’s already a complete sell out.

To celebrate its 50th birthday, a massive on-track parade of 911 Porsche 911s is being staged as one of the many highlights at the annual Silverstone Classic. The cavalcade has proved so popular that it has already attracted more than 1000 registrations meaning the organisers now have closed entries.

As well as the parade, Porsche Cars GB has prepared its own historic 911 race car to compete at the Classic. The 1965 ‘short-wheelbase’ is entered under the evocative ‘Project 50’ team banner and will raced by Richard Attwood and Gordon Robertson in Saturday evening’s blue riband Piper Heidsieck International Trophy Race for Pre-1966 GT Cars, in association with Chopard.

As well as raising much needed funds for the Hope for Tomorrow cancer charity, the spectacular Silverstone Classic 911 x 911 parade – taking place at lunchtime on Sunday 28 July – will feature many of the most famous competition and showroom models from past and present eras including legendary Carrera, RS, RSR, GT, Speedster, Targa and Turbo variants…

Nick Wigley, Event Director said: ‘It’s terrific that so many 911 enthusiasts and Porsche Club Members will be able to join us for what’s going to be a fantastic birthday party; to be marking such an important automotive milestone in such record breaking style is what we always set out to accomplish. It’s going to be a mind-boggling experience no Porsche fan will want to miss.’

Adult admittance is from £35 and considerable savings are on offer for those festival goers spending the full weekend at Silverstone and special packages for car clubs and their members are also available. Full details can be found at www.silverstoneclassic.com.
