context_page_description: The 2015 6 Hours of Silverstone was an endurance sports car racing event held for Le Mans Prototype and Le Mans Grand Touring Endurance cars at the Silverstone Circuit near Silverstone, Northamptonshire, England on 10–12 April 2015 before a crowd of 45,000 spectators. The event served as the opening round of the 2015 World Endurance Championship; it was fourth running of the event as part of the championship.
  The No. 17 Porsche 919 Hybrid of Timo Bernhard, Brendon Hartley and Mark Webber qualified in pole position by setting the fastest lap in class. They maintained the lead for the opening 80 minutes until they suffered a terminal rear drivetrain failure. This allowed the sister No. 18 car driven by Marc Lieb, Neel Jani and Romain Dumas to take over first position. Thereafter, the crew of the No. 18 Porsche battled the No. 7 Audi R18 e-tron quattro of André Lotterer, Marcel Fässler and Benoît Tréluyer for the lead throughout much of the event. This led to multiple overtakes by the No. 7 team that were repelled soon after by the No. 18 Porsche team. It had the advantage of being faster in a straight line, but the Audi was better in the track's corners. Although the No.
context_section_description: Twenty-nine cars were officially entered for the 6 Hours of Silverstone with most of the entries in the Le Mans Prototype 1 (LMP1) and Le Mans Prototype 2 (LMP2) classes. The 2014 race winners, Toyota, returned to defend their title. Three manufacturers, Porsche, Toyota and Audi Sport Team Joest, were represented in LMP1 by two cars each. Team ByKolles were the sole LMP1 privateer team partaking in the race. Nissan were scheduled to debut two GT-R LM Nismos at the circuit but decided to forego the season's opening two rounds after issues with the vehicle during testing. The team decided to focus on making its debut at the 24 Hours of Le Mans. Similarly, Rebellion Racing signed a contract to run Advanced Engine Research V6 twin-turbocharged engines instead of Toyota V8s they had used since 2012. This prompted the outfit to withdraw from the season's first two races so they and chassis developer Oreca could adapt the R-Ones for the new engine. After the retirement of nine-time 24 Hours of Le Mans winner Tom Kristensen, Audi internally promoted Oliver Jarvis to the squad. ByKolles's Simon Trummer was stranded in Switzerland due to a French air traffic control strike, and Christian Klien was contacted on the day of the first practice session to take his place.
  LMP2 consisted of eight cars with twenty-seven drivers in four different types of chassis. Defending LMP2 champions SMP Racing and driver Sergey Zlobin opted not to return, instead focusing on the European Le Mans Series (ELMS) to develop their new BR01 chassis. 2013 category champions OAK Racing returned to the World Endurance Championship (WEC) under their own banner for team owner and driver Jacques Nicolet. Their G-Drive Racing team, which won four races the previous year, expanded to a two-car operation for 2015. All three entries utilised the Ligier JS P2-Nissan. KCMG also remained in the series for 2015, replacing their Oreca 03R with the newer 05 chassis. Strakka Racing, who had filed a full-season entry in 2014 but failed to race after development delays with their Strakka Dome S103 chassis, returned for 2015 with an unchanged programme.
  Defending ELMS champions Signatech, who previously participated in 2012, had backing from Alpine with their Oreca-based A450 chassis with Nissan power. Morand Racing also shifted from the ELMS, partnering with the Japanese firm SARD in a joint effort. The team initially entered two improved versions of the Morgan LMP2 with Judd engines. Problems with a sale to data encryption company Kairos, however, meant the team missed the 6 Hours of Silverstone. Extreme Speed Motorsports was the series' sole North American-representative. They shifted from the United SportsCar Championship to the WEC, with their duo of HPD ARX-03bs after a pre-season testing issue forced them to discard the newer 04 chassis. One of their drivers Johannes van Overbeek injured his rib due to a coughing fit the week before and was replaced by 2009 Le Mans co-winner David Brabham.
  The Le Mans Grand Touring Endurance Professional (LMGTE Pro) field consisted of three manufacturers (Aston Martin, Ferrari and Porsche), while the Le Mans Grand Touring Endurance Amateur (LMGTE Am) entrants included six teams: Aston Martin Racing, AF Corse, Larbre Compétition, Dempsey-Racing Proton, Porsche Team Manthley, and SMP Racing. Three-time LMGTE champions AF Corse's Ferraris had a near identical line-up, and Porsche Team Manthey also kept the drivers for its two cars largely unchanged. Aston Martin Racing expanded their effort to three cars for 2015 after partner Young Driver's entry, which won the LMGTE Am category in 2014, moved to the Pro class. They again fielded two vehicles in the LMGTE Am class. AF Corse also remained in the category, downgrading from a two-car entry to a single car. Porsche added a second vehicle for Manthey Racing. 2012 LMGTE Am Teams' champions Larbre Compétition returned to the series for the first time in two years, campaigning the first customer Chevrolet Corvette C7.R.
