An analysis is provided of the differing market requirements and some thoughts on the market specific products that would be competitive. Conventional vehicles will also continue to offer improved fuel economy and driveability such that future Hybrid products will also need to evolve to deliver further consumer benefits to be successful in the medium term. These vehicles will also need to demonstrate benefits over a wide range of operating cycles with robust operating strategies. Optimisation methods now in use at Ricardo provide an example of how this might be achieved. In this study, Ricardo has reviewed the drivers for change in global marketplaces along with the capabilities of different non-Hybrid and Hybrid powertrain technologies, to consider the most appropriate technologies for passenger cars, light and heavy commercial vehicles. The findings can be summarized as follows: Gasoline Hybrid systems offer fuel economy benefits based on regulated cycles compared with conventional vehicles. However, it is likely that these benefits must be translated into recognised real world consumer experiences for further market penetration. Gasoline based Hybrid system penetration in Europe will be limited by significant competition from conventional diesel vehicles The US market may offer the most opportunities for full gasoline based Hybrid vehicles. Stop/start systems are likely to become widespread in Europe. Although stop/start systems would deliver significant real world economy benefits in the Japanese market, consumer demand for high technology products has driven growth in more sophisticated higher cost products Cost reduction will be a key requirement for future Hybrid products. A strategy based on belt ISG systems and Hybridised dual clutch transmission is proposed for the European market Future Hybrid vehicles will need to demonstrate further benefits in performance, fuel economy and driveability to be competitive. More holistic optimisation will be required.
