Jeddah to be F1's fastest and longest street circuit

(Reuters) - Formula One unveiled its longest and fastest street circuit on Thursday, predicting top speeds of 322kph and wheel-to-wheel racing when Saudi Arabia hosts a race for the first time in Jeddah in December.

Organisers said the Dec. 5 night race in the Corniche area of the Red Sea port city will be over a 6.175km layout, making it the sport's second longest track after Belgium's Spa-Francorchamps.
