F1 W07/04 Hybrid: Power Unit Deep Dive

The W07/04 Hybrid is powered by the PU106C designed and manufactured by Mercedes AMG High Performance Powertrains

Part of what makes the Sonoma Speed Festival so unique for fans of motorsport this year is the arrival of the Mercedes-AMG Petronas Motorsport team to run their W07/04 Hybrid.

Unlike any other public demonstration by any other Formula 1 team, this weekend will feature the U.S. first for a modern era V6 engine powered car to be demonstrated outside of a Grand Prix – just for our guests!

To give you some background and understanding of the complexity of such a demonstration, here’s some viewing you will find helpful.

To get you up to speed:

The beating heart of any car is its engine, and in the F1 W07 Hybrid’s case termed a ‘Power Unit’, the PU106C, and it’s where energy is generated, harvested and stored.

Consisting of a V6 cylinder turbocharged internal combustion engine for most of its power, it’s been closely integrated with a software controlled charging and battery energy storage and electric motor output system.

The W07/04’s PU106C power units are developed and built by Mercedes-AMG High Performance Powertrains (HPP) in Brixworth, UK, a separate facility from the Mercedes-AMG Petronas Motorsport Team’s HQ in Brackley, which designs, tests and develops their chassis, suspension, aerodynamics and electronics.

Together, they employ roughly 1,500 skilled engineers, designers, mechanics, technicians and support staff.  Just 60 are in attendance at any given race, and this weekend several will be in attendance to demonstrate the W07/04.

For the technically minded, and for more on power unit specifics, these infographics and short videos give a glimpse into the team’s inspiration, work, and accomplishments with the PU106C:
