MP4/4

Lore & Background

Honda had provided the Constructors' Championship-winning engines of 1986 and 1987, and for 1988 they switched partners from Williams to McLaren, who had struggled with their dated TAG-Porsche engines. The engine's design and development was led by Osamu Goto. The MP4/4 was a distinctly lower design than the previous year's MP4/3, forcing the drivers into a more reclined, almost lying down driving position. In the 1988 season the MP4/4 won all but one race and claimed all but one pole position.

The team won the year's constructors' title with about three times as many points as runners-up Ferrari. The car held the record for highest percentage of laps led in a season until 2002, when the Ferrari F2002/F2001B surpassed it with 97.5%. The car held the record for the highest win rate in a season until 2023, when the record was broken by the Red Bull Racing RB19, which was powered by a Honda-Red Bull Powertrains (HRC) V6 turbo hybrid engine (95.45% win rate).

The McLaren MP4/4 was not the first turbo-powered McLaren to win the World Constructors' Championship in the modern turbo era, as McLaren had already won with turbo engines in 1984 and 1985. The subsequent MP4/5 (1989) and MP4/5B (1990) won the Constructors' Championship with naturally aspirated V10 engines, not turbocharged ones.

Reader's Guide

The MP4/4 was produced and first appeared early in 1988. It was one of the few competing cars that year that was an all-new car. Due to the car's low-slung aerodynamics and FIA safety rules, the drivers were required to be in a reclining position. The car appeared 'as-is' through the season, save for a few aerodynamic revisions. The dominant run was only interrupted once, at the Italian Grand Prix at Monza for Round 12, when Senna crashed out of the lead with only two laps remaining while lapping Jean-Louis Schlesser. With Prost already out after a rare engine failure, Gerhard Berger claimed an emotional victory for Ferrari. The car retired only four times in the season: Prost retired at Silverstone (handling) and at Monza (engine), along with Senna's accidents at Monaco and elsewhere.
