McLaren MP4/7A
The McLaren MP4/7A was McLaren International's Formula One entry for the  season, and a follow-up to their successful MP4/6 from . Background 
The Williams-Renault combination was getting faster and more reliable and became a formidable challenger to McLaren's dominance. McLaren used the MP4/6 chassis, now designated MP4/6B for slightly modified front wing aerodynamics, for the first two races of 1992. The all-new MP4/7A was expected for the Spanish Grand Prix, the fourth race of the year. However, due to Williams' speed in pre-season testing (as well as their dominance of the first two rounds of the season), McLaren team principal Ron Dennis made the decision to bring the car out one race early, at the Brazilian Grand Prix. This was one month earlier than expected. Design 
This was the first McLaren to use a semi-automatic transmission; it was a McLaren-designed electro-hydraulic clutch and paddle-shift unit with semi-automatic activation (a semi-automatic transmission had been tested during the previous season with the MP4/6 and was on track during practice for the 1991 Hungarian Grand Prix, but the team elected to retain that car's original manual transaxle for the entirety of that car's use in competition). The team's technology partner Techniques d'Avant Garde (TAG) helped with development. This system allowed the driver to keep his foot on the pedal, without lifting from it since the throttle cable was replaced with an electronic sensor. It also controlled engine speed, rev-matching, and clutch actuation automatically during gear changes. The MP4/7A also gained traction control at the Hungarian Grand Prix. A variant of the car, dubbed MP4/7B, featuring an experimental active suspension system, was introduced in testing for that year's Portuguese Grand Prix, though it proved insufficiently reliable and was not used for the remainder of the 1992 season. The system would, however, be used on the MP4/7A's replacement, 's MP4/8. With Honda pulling out of Formula One at the end of the 1992 season (after 69 wins as an engine supplier since , 44 of them with McLaren), the team would be forced to use customer Ford V8 engines in 1993, thus the MP4/7A was the last McLaren to use the Japanese engines until the McLaren Honda partnership was renewed prior to the  season; the failure of that partnership to produce a race-winning car means the MP4/7A remains the last Honda-powered McLaren Formula One car to win a Grand Prix. Season summary
For the first time since , McLaren failed to capture the Constructors' or Drivers' Championship title. It was, therefore, the first time the team had failed to win the championships with Honda power, as the years  to  had all been successful in this respect. While the MP4/7A showed that it was able to keep up with the Williams FW14B in a straight line on several occasions, the active suspension on the Williams allowed it to better utilize its aerodynamic package, thus relegating the passively-suspended McLaren to 'best of the rest' status. The MP4/7A also suffered from teething troubles early on: both Senna and Berger dropped out of the car's debut race in Brazil with electrical problems. Defending champion Senna also suffered three straight DNFs during the middle of the season, effectively ending any hopes he may have had at defending his title. Five Grand Prix victories were recorded by the drivers: three for Ayrton Senna, in his fifth season for the team, and two for Gerhard Berger in his third and final season for McLaren before switching back to Ferrari for 1993.
