The programme and system level design, both conceived by Ricardo, have combined electronically controlled Valeo 42 Volt systems and Ricardo’s powertrain, integration and control expertise.


Valeo claims that i-MoGen is set to become the benchmark in production-ready fuel saving technologies, achieving a 28% improvement in fuel economy without compromising vehicle performance, driveability or comfort. Valeo also says that i-Mogen meets all future anticipated emissions legislation.


i-MoGen, based on a current production Opel Astra, has been equipped with a Ricardo-developed high output down-sized 1.2 litre,74kW diesel engine and a programmed supervisory controller that links Valeo’s 42 Volt systems.


The 42 Volt systems from Valeo include an integrated starter-alternator, a DC/DC converter, an advanced battery management system, intelligent engine cooling and a Heating Ventilation and Air Conditioning (HVAC) system.

Martin Haub, Valeo Group Vice President, R&D and Product Marketing, commented, “With this demonstration platform, I believe that Valeo and Ricardo have proved that a combination of down-sized engine, integrated starter-alternator and 42 Volt systems can deliver impressive fuel savings. i-Mogen also highlights the importance of the skillful systems engineering required for the successful integration of so many different systems. Considerable engineering effort has culminated in this practical vehicle that despite its huge fuel savings compromises neither performance nor driveability. This is what makes this
mild hybrid diesel vehicle truly unique.”
