Unveiled back in 1961 at the Geneva Motor Show, the Jaguar E-Type has since become synonymous with classic British design. In honour of its 50th anniversary, we're offering up five pairs of tickets for this year's Goodwood Festival of Speed where the E-type's birthday will be marked in style.

On its launch, the E-Type was the world's fastest production car, capable of a reported 151mph. Its distinctive profile is the work of designer Malcolm Sayer, and evolved from the Le Mans 24 Hour race-winning Jaguar D-Type race car.

Ferrari’s founder Enzo Ferrari even described the E-Type to be “the most beautiful car ever built” when he first saw it, while America’s Road & Track magazine really got to the heart of the matter by calling it: “the greatest crumpet collector known to man.”

Jaguar has a long history at Goodwood, including the E-Type's own impressive racing record at the Sussex circuit from the 1960s. At this year's 19th Festival of Speed,  the E-type will be the subject of a special installation showcasing its story, and will also feature examples of notable racing E-Types on the Goodwood Hill run.

We have five pairs of tickets for Sunday 3 July at the Goodwood Festival of Speed, plus each winner will also get a copy of Jaguar's official collectors' edition coffee table book - 50 Years of a Design Icon. To enter, email your name, address and phone number to online@esquire.co.uk by midnight on Sunday 12 June putting 'Festival of Speed' in the subject header.
