Mark Temple is a British Formula 1 engineer and McLaren's Technical Director, Performance, appointed in May 2024 as part of Andrea Stella's restructured technical leadership. He has spent his entire F1 career at McLaren. ¹²

Early McLaren years

Temple joined McLaren in October 2003 as a transmission designer. He moved into the vehicle technology team in 2005, working on suspension and ride analysis, became an assistant test engineer in 2008, and joined the race team in 2009 as a tactician and operations engineer. ¹²

“In 2017 Temple shifted to factory-based work as team leader for simulation development, rising to Principal Performance Engineer.”

Race engineering

From 2010 to 2011 Temple was Lewis Hamilton's performance engineer, and he became Hamilton's race engineer from the 2012 Singapore Grand Prix onwards. ¹ He has pointed to Hamilton's drive from the back of the grid at the 2012 Spanish Grand Prix, where extreme tyre management carried him to eighth, as a "switch-on" moment for the future seven-time champion. ³ Temple subsequently race-engineered Sergio Perez, Kevin Magnussen and Fernando Alonso through to 2017, later calling Alonso the most intelligent driver he had worked with. ¹⁴

Factory and performance roles

In 2017 Temple shifted to factory-based work as team leader for simulation development, rising to Principal Performance Engineer. Following McLaren's 2023 restructuring he built out the team's car, driver and competitor performance group, benchmarking McLaren against its rivals. ¹²

Technical Director, Performance

In May 2024 Temple was promoted to Technical Director, Performance, completing Stella's restructure alongside chief designer Rob Marshall, aerodynamics director Peter Prodromou and engineering director Neil Houldey, all reporting to Stella. He leads the Performance and Concept department covering vehicle performance, tyres and brakes, and driver and competitor performance, the group that benchmarks McLaren against its rivals and turns data and driver feedback into car-development direction. McLaren describes his approach as blending objective measurement with subjective driver insight to unlock performance, a brief that draws directly on his years on the pit wall. ¹²⁵

Voice on the 2026 regulations

Temple has become a prominent McLaren technical voice on Formula 1's 2026 rules. In January 2026 he explained that the need to "harvest energy more consciously and then choose where you use it is going to be critical," calling the simulator the best tool for preparing drivers and predicting a "cat and mouse" learning curve in attacking and defending under the new power-unit rules. He expects meaningful performance differentiation between cars and power units once the season begins. ⁶⁷

Bottom line

Temple is a McLaren lifer whose two decades at the team span gearbox design, race-engineering a world champion and now leading its performance organisation. He is one of the senior technical directors underpinning McLaren's back-to-back Constructors' titles and its 2026 preparation. ¹²
