The '''Ligier JS27''' was the [[Formula One]] car with which the [[Equipe Ligier|Ligier]] team competed in the {{F1|1986}} season.
The '''Ligier JS27''' was the [[Formula One]] car used by French team [[Equipe Ligier|Ligier]] to compete in the {{F1|1986}} season.


==Concept==
==Description==
The JS27 was a logical development of the previous year's [[Ligier JS25|JS25]], with a lower fuel tank and revised aerodynamics. It was also lighter than its overweight predecessor, with the customer supply of [[Renault F1|Renault]] engines more effectively integrated into the overall package than before, although the specification of the engines was always slightly behind fellow-Renault users [[Team Lotus|Lotus]] and was not developed through the course of the season.
The JS27 was a development of the previous year's [[Ligier JS25|JS25]], with a lower fuel tank and revised aerodynamics to take advantage of the fuel limit which had been reduced from 220 to 195 litres. It was also lighter than its overweight predecessor, with the customer supply of [[Renault F1|Renault]] engines more effectively integrated into the overall package than before, although the specification of the engines was always slightly behind fellow-Renault users [[Team Lotus|Lotus]] and was not developed through the course of the season.

==Construction==
Three JS27 chassis were built and ready to race for the first round of the championship in [[1986 Brazilian Grand Prix|Brazil]], and a further two were constructed during the course of the season: chassis 04 was introduced for the [[1986 Belgian Grand Prix|Belgian Grand Prix]], whilst chassis 05 was ready in time for the race in [[1986 Canadian Grand Prix|Canada]]. Chassis 01 was written off due to the extensive front-end damage caused by [[Jacques Laffite]]'s career-ending accident at the [[1986 British Grand Prix|British Grand Prix]].

The JS27 was initially driven by the [[France|French]] pairing of Ligier mainstay Laffite and [[René Arnoux]]. Both drivers were renowned as being fast and experienced, but their age and setup skills were cast into doubt before the start of the season. Arnoux, in particular, had missed all but the first race of the {{F1|1985}} season after being sacked after the [[1985 Brazilian Grand Prix|Brazilian Grand Prix]] by Ferrari, and at 42 years old, Laffite was the oldest driver on the grid.

The latter had missed all but the first race of the {{F1|1985}} season after being sacked after the [[1985 Brazilian Grand Prix|Brazilian Grand Prix]] by [[Scuderia Ferrari|Ferrari]] (neither Ferrari nor Arnoux have ever gone public with the reason for his sacking); at 42 years old, Laffite was the oldest driver on the grid.

The JS27 was instantly competitive, however, with numerous points finishes in the first half of the season, including two podium finishes from Laffite. At [[1986 United States Grand Prix|Detroit]], both drivers were particularly fast, Laffite leading the race and eventually finishing third, whilst Arnoux looked on course for second place until he crashed. By the time of the British Grand Prix, Ligier were fourth in the Constructors' Championship: behind [[WilliamsF1|Williams]], [[McLaren (racing)|McLaren]] and Lotus, but ahead of Ferrari.

By the time of the British Grand Prix, Ligier were fourth in the Constructors' Championship, behind [[WilliamsF1|Williams]], [[McLaren (racing)|McLaren]] and Lotus, but ahead of Ferrari. This race, however, saw Laffite caught up in a first-lap pile-up, seriously injuring his legs.

This race saw the team sustain a major setback, when Laffite was caught up in a first-lap pile-up and seriously injured his legs. The crash effectively ended his Formula One career, as he chose not to return once his injuries had healed. It also spelt the end for the [[Brands Hatch]] circuit in F1, and triggered new safety regulations for following years, the most obvious of which stipulated that a driver's feet had to be situated beind the car's front [[axle]] line for {{F1|1988}}.


Laffite's accident caused the Ligier team's morale to drop, and with a concurrent lack of development on the chassis, the JS27 was less competitive in the second half of the season. Arnoux and substitute driver [[Philippe Alliot]] could only score for points from the [[1986 German Grand Prix|German Grand Prix]] onwards, but this was enough to secure fifth in the Constructors' Championship - the highest-placed team using [[Pirelli]] tyres.

The JS27 was one of the last truly competitive cars to be produced by the Ligier team; from 1987 the team would suffer a competitive slump that would last until the {{F1|1993}} season. The JS27 was also the last Ligier chassis to lead a lap of a Grand Prix until [[Olivier Panis]]' victory in the [[1996 Monaco Grand Prix]], Ligier's last season in F1 before its takeover by [[Prost Grand Prix|Alain Prost]].

The Ligier JS27 was the Formula One car used by French team Ligier to compete in the 1986 season.

Description[edit]

The JS27 was a development of the previous year's JS25, with a lower fuel tank and revised aerodynamics to take advantage of the fuel limit which had been reduced from 220 to 195 litres. It was also lighter than its overweight predecessor, with the customer supply of Renault engines more effectively integrated into the overall package than before, although the specification of the engines was always slightly behind fellow-Renault users Lotus and was not developed through the course of the season.

Three JS27 chassis were built and ready to race for the first round of the championship in Brazil, and a further two were constructed during the course of the season: chassis 04 was introduced for the Belgian Grand Prix, whilst chassis 05 was ready in time for the race in Canada. Chassis 01 was written off due to the extensive front-end damage caused by Jacques Laffite's career-ending accident at the British Grand Prix.

Racing history[edit]

The JS27 was initially driven by the French pairing of Ligier mainstay Laffite and René Arnoux. The latter had missed all but the first race of the 1985 season after being sacked after the Brazilian Grand Prix by Ferrari (neither Ferrari nor Arnoux have ever gone public with the reason for his sacking); at 42 years old, Laffite was the oldest driver on the grid.

The JS27 scored numerous points finishes in the first half of the season, including two podium finishes from Laffite. At Detroit, Laffite led the race and eventually finishing second, whilst Arnoux was on course for second place until he crashed. By the time of the British Grand Prix, Ligier were fourth in the Constructors' Championship, behind Williams, McLaren and Lotus, but ahead of Ferrari. This race, however, saw Laffite caught up in a first-lap pile-up, seriously injuring his legs. The crash effectively ended his Formula One career, as he chose not to return once his injuries had healed.

Due to Laffite's accident and a concurrent lack of development on the chassis, the JS27 was less competitive in the second half of the season. Arnoux and substitute driver Philippe Alliot could only score four points from the German Grand Prix onwards, but this was enough to secure fifth in the Constructors' Championship - the highest-placed team using Pirelli tyres.

After the JS27, the team would suffer a competitive slump that would last until the 1993 season. The JS27 was also the last Ligier chassis to lead a lap of a Grand Prix until Olivier Panis' victory in the 1996 Monaco Grand Prix, Ligier's last season in F1 before its takeover by Alain Prost.
