Versatile Danish driver Allan Simonsen has died from injuries sustained in an accident during the opening laps of the Le Mans 24 Hours.
The 34-year-old lost control of his Aston Martin Racing Vantage at the exit of the Tertre Rouge corner on just the third lap, making heavy contact with the barriers on the left-hand side of the circuit.
The Safety Car was required for more than an hour as officials attended to Simonsen and repaired the barriers.
A statement from race organisers the Automobile Club de l'Ouest subsequently confirmed that Simonsen died from his injuries after being transferred to the circuit's medical centre.
Simonsen started the race from the GTE Am pole position and had been co-leading the 2013 World Endurance Championship pointscore for the class with co-drivers Christoffer Nygaard and Kristian Poulsen.
The popular Dane is the first driver to be killed in the Le Mans 24 Hours since Jo Gartner in 1986.
Aston Martin Racing says that, at the specific request of Simonsen's family, it will continue in the race with its remaining four cars in tribute.
Simonsen had carved out a diverse globetrotting career over the last decade, with GT racing quickly turning into a specialty.
His success in GTs included winning the GT2 class of the 2009 Asian Le Mans Series and scoring outright honours in the 2007 Australian GT Championship.
Simonsen was a regular fixture in Australia, making V8 Supercars endurance race starts for Garry Rogers Motorsport (2003 and 2004), Perkins Engineering (2005), Triple Eight (2006, 2007 and 2009), Paul Morris Motorsport (2010), Kelly Racing (2011), Brad Jones Racing (2011, Gold Coast) and Dick Johnson Racing (2012).
Simonsen's time in Australia also included a V8 Ute Series campaign in 2005 and a host of Nations Cup and GT Championship appearances, most recently driving with Maranello Motorsport in February's Bathurst 12 Hour.
Simonsen's time with Maranello saw him temporarily hold the outright lap record around Australia's premier racing circuit at Mount Panorama, Bathurst.
The time of 2:04.96s was set during the Sprint Bathurst hot lap event in November, 2011, and stood until it was bested by a Formula 3 car in April the following year.
Tributes to Simonsen began flooding in from all corners of the motor racing industry immediately after his passing was confirmed.
The ACO says it will make no further statement on the death until the exact reasons for the accident are determined.
Simonsen is survived by his partner Carina and daughter Mie-Mai.
Speedcafe.com passes on its condolences to the Simonsen family and friends, including the many he had in Australia.
