McLaren and its historic V10 engine: a Formula 1 legend

Introduction

We thank you for joining us to explore the history of McLaren, one of the most iconic teams in Formula 1, which made its mark in 1989‑1990 with the legendary V10 engine developed by Honda.

Technological context

From the 1989 season, turbocharged engines were banned in Formula 1 and naturally aspirated units were limited to 3.5 litres. 

Honda then built the 3 493 cc V10 engine “RA109E” which was supplied to McLaren for 1989. 

Performance and evolution

The RA109E featured a 72° V‑angle, and development began in 1987. According to estimates, the engine produced around 675 hp at 13 500 rpm.

In 1990, Honda evolved the engine into the “RA100E” version with bore of 93 mm and stroke of 51.5 mm, improving combustion stability and reliability. 

Sporting success

With this engine, McLaren secured multiple Grand Prix wins and maintained its champion status. For example, the McLaren MP4/5B, powered by the RA100E, achieved 6 wins during the 1990 season.

Legacy

The Honda‑McLaren V10 engine remains an icon of the naturally aspirated era of F1. It helped cement the V10 configuration as a competitive option for many years. 

Conclusion

We thank you for your interest in this chapter of history: the McLaren Honda V10 engine is more than figures — it embodies innovation, performance and the competitive spirit of a bygone yet unforgettable era.
