At the end of Season 3, A1GP released the results of the season's pit stop times. Although having never won a race, A1 Team Australia had the fastest pit crew of all teams. Scoring Unlike almost all other forms of auto racing, drivers did not score points individually; instead the points they earn were ascribed to their national team. This means that teams could change drivers between rounds, which was often necessary because some drivers had commitments in other formulae, and still accumulate points to their score. Points were awarded for the first ten places but the amounts changed during the series' run: 15 for the winner, 12 for second place, 10 for third place, 8 for fourth place, 6 for fifth place, 5 for sixth place, and so on with 4, 3, 2, and one point for tenth place. Points were awarded in a different way for the Sprint Race: 10 for the winner, counting down 8, 6, 5, 4, 3, 2, and 1 point for eighth place. In addition, one point was awarded to the team that set the fastest single lap time in either the Sprint or Main Race. Cash prizes were also awarded. Below is a list of pointscoring systems used to determine the winner of the A1 Grand Prix World Cup of Motorsport since the 2005–06 season. The World Cup of Motorsport was awarded to the A1 Grand Prix team which accumulated the most points over the course of a season. Chassis and engines The A1GP formula provided a single "spec" car for each team. Each car was mechanically identical, built with many technical restrictions designed to limit performance, reduce running costs, and prevent any one or number of teams gaining an advantage through better equipment. This regulation provided a level playing field in which driver skill and team effort should become the primary factor for success. Specifically, the cars (in the series' final season) had a carbon fibre monocoque with an aluminium honeycomb core chassis based on the Formula One Ferrari F2004 chassis, riding on control slick tires from Michelin. The 4.5-litre Ferrari/Maserati V8 engine was capable of delivering up to in PowerBoost mode – a mechanism to provide short bursts of increased power to create additional overtaking opportunities and action throughout the race. Previous seasons used the Lola B05/52 (branded as "Lola A1GP") running on 3.4-litre Zytek engines delivering up to in PowerBoost
