The RBPTH001 was, despite its name, developed, produced, and maintained by Honda. It was a derivative of the Honda RA621H, with different ignition timing, cylinder pressure, and MGU-H to account for the new E10 fuels. The crankshaft and cylinder block geometry were also modified to ensure reliability when running on E10 fuels, and a specialised coating developed by Honda's motorcycle division was applied to the walls of the cylinders. The injection system, exhaust, and the turbocharger's compressor and turbine were all optimised for E10 fuel. The changes meant that the RBPTH001 weighed more than the RA621H, but the dimensions of the engines are virtually identical save for the exhaust and intake layout and the electrical components. The new engine could also run at noticeably higher temperatures compared to the RA621H. Despite the reduced energy density of the 2022 fuels, the RBPTH001 had greater thermal efficiency than its predecessor.
