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

Organizers said the December 5 night race in the Corniche area of the Red Sea port city will be over a 6,175 km layout, making it the sport’s second longest track after Belgium’s Spa-Francorchamps.

Largely using existing roads, and encircling a lagoon, the floodlit circuit will feature 27 corners with cars lapping at average speeds of 252.8kph, according to Formula 1’s simulations.

That would put it behind Italy’s Monza, the fastest of any circuit, but ahead of Britain’s Silverstone in terms of outright speed.

Formula One’s motorsport managing director Ross Brawn said the layout would create plenty of overtaking opportunities and wheel-to-wheel racing.

“We don’t want Mickey Mouse circuits,” he told the F1 website.

“We don’t want those old classic street circuits where you turn 90 (degrees). We want fast, sweeping circuits, we want circuits that are going to challenge the drivers and they are going to love it. We want circuits where we can have wheel-to-wheel racing.”

The fastest street circuit at the moment, for average speeds, is Melbourne’s Albert Park at 237.2kph. The longest is Azerbaijan’s Baku at 6.003km.

“This is a circuit that is utilizing some existing infrastructure but we’ve been lucky that there are areas where we’ve been able to build from scratch,” said Brawn.

“So we’ve been able to build some really exciting parts of the circuit.At one end, there will be a 180 degree corner with a moderate amount of banking, so it will be a high G-load and high stress for the drivers.”

The Saudi race is due to be the penultimate round on a record 23 race calendar.

“When you have a high-speed street circuit it doesn’t leave much room for error,” said Brawn.

“I hope we can have a championship that’s maintained to the end and this will be definitely a fitting venue to have those final battles in the championship.”
