Power Unit parts and their functions
10 top-level parts · 120 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Engine Block | 1× | Cast aluminum 90-degree V6 block machined to take chassis and gearbox loads through its structure. |
| 2 | Racing Piston | 6× | Machined-billet piston surviving mean piston speeds near 26 m/s at 15,000 rpm. |
| 3 | Crankshaft | 1× | Nitrided steel flat-plane crank weighing under 6 kg. |
| 4 | Pneumatic Valvetrain | 1× | Valve springs replaced by nitrogen pressure, allowing valve closure at rev limits no steel spring can follow. |
| 5 | Turbocharger | 1× | Single turbo spinning to 125,000 rpm, often with the compressor and turbine split across the engine vee. |
| 6 | MGU-K | 1× | Kinetic energy recovery |
| 7 | Energy Store 4 parts | 1× | The battery pack under the fuel cell, cycling about 4 MJ per lap between recovery and deployment. |
| 8 | Airbox | 1× | Roll-hoop intake feeding rammed induction air to the engine plenum. |
| 9 | Exhaust System | 1× | Inconel headers and tailpipe running gas temperatures near 1,000 °C. |
| 10 | Dry Sump System | 1× | Scavenge pumps and remote tank keeping oil pressure under 5 g cornering and letting the engine sit 50 mm lower. |
