The presentation will cover major design characteristics of the Ultraboost project engine, the test results and the project findings. Approximately 35% reduction in simulated fuel consumption was shown when comparing the 2010 V8-engined Range Rover with a 2013 version with an Ultraboost engine. The present limit to downsizing is discussed, and the next steps for this technology is raised.

The presentation discusses work within the Ultraboost project, which started in 2010, to ascertain the limits of extreme downsizing. Downsizing is a megatrend within the automotive industry, providing as it does a cost-effective route to lower fuel consumption and CO2 emissions from affordable, mass-produced technology, especially in the case of spark-ignition engines.

The eight project partners, including the University of Bath, Jaguar Land Rover, Lotus Engineering and Imperial College London, collaborated to produce a 2.0 litre engine capable of giving the performance of a 5.0 litre naturally-aspirated V8. Bath was the test facility while Imperial led the configuration and testing of the charging system. The project was part-funded by the Technology Strategy Board, the UK’s innovation agency.
