The Mercedes AMG F1 W08 EQ Power+ was a Mercedes-Benz Formula One racing car designed and developed under the direction of Paddy Lowe, Aldo Costa, Geoff Willis, Loïc Serra, Russell Cooley, John Owen, Mike Elliott and Jarrod Murphy to compete during the 2017 Formula One World Championship. The car was driven by three-time World Drivers' Champion Lewis Hamilton, who remained with the team for a fifth season, and Valtteri Bottas, who joined the team after 2016 World Champion Nico Rosberg's retirement from the sport.
The chassis was originally named the "Mercedes F1 W08" to represent the eighth Formula One car that Mercedes had constructed since 2010. The "EQ Power+" was added to increase exposure of Mercedes' electric road car models, whilst AMG was included to reflect the relationship between Mercedes-AMG and Mercedes-Benz. The car made its competitive début at the 2017 Australian Grand Prix, the opening round of the 2017 season. After participating in 19 rounds of Grand Prix racing, the car made its final competition appearance at the season finale race – the 2017 Abu Dhabi Grand Prix, before retirement.
The F1 W08 EQ Power+ took twelve wins (nine for Hamilton and three for Bottas), fifteen pole positions (eleven for Hamilton and four for Bottas), nine fastest laps (seven for Hamilton and two for Bottas) and four 1-2 finishes. The team clinched their fourth consecutive Constructors' Championship at the United States Grand Prix, the 17th race of the season with three races to spare. Hamilton clinched his fourth World Drivers' Championship at the season's next round, the Mexican Grand Prix.
