100 Grands Prix and counting - the V8 centenary
This weekend’s Hungaroring round, the Formula 1 Eni Magyar Nagydij 2011, will be a race of anniversaries, including 100 Grands Prix for Mercedes’ Nico Rosberg and 200 for the (Mercedes-powered) McLaren driver Jenson Button. But it will also mark a technological milestone for the sport, as the 2.4 litre V8 engine competes in its 100th race. Courtesy of Mercedes, here's a summary of what the engine has achieved since its very first appearance in Bahrain back in 2006...
Q: What has been the history of the 2.4 litre V8 engine since it was introduced in 2006?
A: Although the engine architecture and capacity has remained the same for the past five and a half seasons, the V8 engine has been operated under a wide variety of regulations. In 2006, development was free, although the engine had to last for two race weekends. For 2007, the engine was homologated (the start of the 'frozen' era) and had to last for two race weekends only including Saturday and Sunday - teams were free to use a different engine on Friday, to encourage them to run during practice, and ran to a maximum rev limit of 19,000 rpm. These rules remained in force for the 2008 season. Since the start of 2009, each driver has been able to call on a pool of eight engines for the entire season, and the maximum engine speed has been fixed at 18,000 rpm. In both the 2009 and 2011 seasons, the engine was also adapted to incorporate the KERS hybrid system.
Q: What are the basic specifications of the Mercedes engine?
A: The 2011 Mercedes engine is codenamed FO108Y and is designed and developed by Mercedes-Benz HighPerformanceEngines in Brixworth, UK. It has a maximum capacity of 2.4 litres, while its architecture is fixed at eight cylinders in a 'V' configuration, with a bank angle of 90 degrees. The engine's minimum weight is fixed by regulation at 95 kilogrammes, and it develops over 750 bhp.
Q: How much mileage does the V8 engine now do?
A: Since the start of the 2006 season, the Mercedes-Benz V8 engine has completed a total of 102,427 race kilometres - 89 percent of the possible total. Under the 2006 rules, each individual engine had a life of around 1,000 kilometres, while each engine now completes approximately 2,000 kilometres.
Q: How many wins has the Mercedes-Benz V8 engine taken?A: The most successful season for the engine was in 2009, when it took a total of 10 race wins (59 percent of the season total), 10 pole positions and five fastest laps - as well as both the drivers' and constructors' championships. The least successful season was in 2006, when the engine won no races. Since the engine was homologated for the start of the 2007 season, it has taken a total of 32 wins from 81 races - a winning percentage of 40 percent.
Q: What other statistics has the engine accumulated?
A: In its 99 races so far, the engine has achieved 30 pole positions, 25 fastest laps and a total of 94 podium finishes with four teams - Mercedes, McLaren-Mercedes, Brawn GP and Force India.
Q: Has the engine achieved any particular milestones?
A: The Mercedes-Benz V8 was the first engine to score three race wins with one engine: in 2009, Jenson Button used engine FW049-01 to win races in Bahrain, Spain and Monaco. The unit went on to be used for Friday practice in Germany and Hungary, accumulating a total of 2,016 kilometres. It also scored two pole positions (Spain and Monaco) and spent 72 percent of its racing laps in the lead. In the same season, engine FW058-01, used by Lewis Hamilton, also became the first hybrid-equipped engine in Formula One history to win a race, at the Hungarian Grand Prix.
