Description

The McLaren MP4/7 was campaigned by McLaren during the 1992 Formula One World Championship. McLaren started the ’92 season with a modified version of the ’91 MP4/6 with plans to switch to the MP4/7 in the fourth round of the season. After seeing the pace of the Williams, team principal Ron Dennis decided to bring the car out one race early at the Brazilian Grand Prix. The car before us today is the MP4/7-4 that debuted in Brazil with Ayrton Senna behind the wheel. After qualifying and starting from P3, Senna unfortunately suffered from an electrical failure resulting in a disappointing DNF.

Design and Technology

• Engine: It was powered by the Honda RA122E/B, a 3.5-liter V12 engine, capable of producing between 764 and 805 horsepower.
• Transmission: The MP4/7A featured McLaren's first semi-automatic transmission, which allowed for quicker and more efficient gear changes.
• Chassis: The car featured a carbon fiber monocoque chassis, which was both lightweight and strong.
• Innovations: It introduced an electronically controlled throttle system (drive-by-wire) and gained traction control during the season.

Performance

• Debut: The MP4/7A made its debut at the Brazilian Grand Prix, the third race of the 1992 season.
• Victories: The MP4/7A model secured five Grand Prix wins—three by Ayrton Senna and two by Gerhard Berger.
• Challenges: Despite its advanced technology, the MP4/7A struggled against the Williams FW14B, which featured active suspension and other high-tech systems.

Legacy

• End of an Era: The 1992 season was the last for McLaren with Honda engines until their partnership was renewed in 2015. The MP4/7A remains the last Honda-powered McLaren to win a Grand Prix.
• Driver Highlights: Ayrton Senna's notable performances included winning the 50th anniversary Monaco Grand Prix, ending Nigel Mansell's six-race winning streak.

The MP4/7A is remembered for its technological advancements and the fierce competition it faced during the 1992 season.
