A Wacky Races-style car wreck stands at the heart of the Royal Academy's Summer Exhibition, which opened its doors this week.

Crash Willy, featuring an old-fashioned car with the number plate FTSE, is a new work by former Turner Prize nominee Yinka Shonibare.

The vehicle's wheels have come off and a headless figure sits on board.

The British-Nigerian artist's fourth plinth artwork, Nelson's Ship in a Bottle, is currently standing in London's Trafalgar Square.

The gallery's annual summer exhibition is billed as the "world's largest open submission contemporary art exhibition".

This year's coordinators, Stephen Chambers and David Chipperfield, have selected works around the theme "raw".

Mr Chambers has said of Crash Willy: "The driver looks as if he has come out worst from a Wacky Races prang."

Other works in the exhibition include a huge King Kong-like monster fashioned from coat-hangers.

The figure, which is beating its chest, is by David Mach and is priced at £265,000.

A Tracey Emin work bears the words Sometimes I Don't Think, with the words "But I love you", scrawled in red.

Now in its 242nd year, the display showcases the work of both emerging and established artists in painting, sculpture, photography, printmaking and film.

The exhibition received more than 11,000 entries this year and most of the 1,267 works are on sale.

The exhibition recognises artists of "exceptional merit", awarding a total of £70,000 prize money.

The Royal Academy's Summer Exhibition is open from Monday to August 22.
