Bentley Motors last week announced a three-year research study that promises to transform electric vehicle powertrains, utilising a fully integrated, free from rare-earth magnet e-axle that supports electric vehicle architectures. This reinforces Bentley’s ambition to lead sustainable luxury mobility and introduce the first fully electric Bentley by 2026. The study, titled OCTOPUS, Optimised Components, Test and simulatiOn, toolkits for Powertrains which integrate Ultra high-speed motor Solutions, follows an initial 18-month investigation that delivered a technological breakthrough in electric drive systems for high-performance vehicles.

Building on the UK’s leading electronics research, the resulting electric drive system exceeded the latest permanent magnet motor performance while simultaneously removing the need for both rare-earth magnets and copper windings, delivering a package both cost effective and recyclable at its end of life. OCTOPUS will take this leading-edge motor, power electronics and packaging transmission design, adding next generation materials, manufacturing processes, simulation and test cycles to deliver a full e-axle powertrain with unique levels of integration and revolutionary performance characteristics suitable for real world application by 2026.

OCTOPUS is an OLEV funded project delivered in partnership with Innovate UK which brings together the following partners with distinct roles and responsibilities:

Bentley Motors – Specification setting, vehicle integration plan and system test

Advanced Electric Machines Ltd – Motor manufacturing and systems assembly

Advanced Electric Machines Research Ltd – Motor and transmission design

The Thinking Pod Innovations Ltd & Nottingham University – Power electronics optimisation and alternative wide band gap system design

The Institute for Advanced Automotive Propulsion Systems at the University of Bath – Integrated system analysis and proof of concept validation testing

HiETA Technologies Ltd – AM component design and manufacture for thermal management including stator core housing, power electronics and E-axle oil cooling

FD Sims Ltd – Next generation wire technology development

Talga Technologies Ltd – 2D materials development for next generation winding technologies

Diamond Light Source – UK’s national synchrotron light source providing access to X-ray facilities for measurements

Hartree Centre (Science and Technology Facilities Council) – Advanced system testing and co-simulation toolkit development
