The HyBoost concept demonstrated that use of a highly downsized, boosted engine in conjunction with relatively low cost synergistic '12+X' Volt management system and electrical supercharger technologies can deliver better value CO2 reduction than a full hybrid vehicle. System incremental cost has been estimated below that of Dieselisation, giving strong potential for market advancement. In summary: (1) The project enabled improvements in the state-of-the-art in stop/start systems and boosting, both of which will become ubiquitous in advanced passenger cars. (2) Full system functionality was achieved and a CO2 glide path identified that was better than first predicted to levels below a current benchmark full hybrid. (3) The HyBoost vehicle is technically a "Hybrid" (a micro/mild hybrid, with up to 6 kW of electrical power) and can be marketed as such, offering similar CO2 performance but without the purchase or lifetime cost concerns of larger battery systems. (4) It was shown that HyBoost technologies can be applied to existing base engines with a relatively low level of re-engineering, thus reducing the cost of implementation in a product range and extending the applicability of the base engine (which may be offered in three or four power trims, from naturally aspirated through boosted to HyBoost configurations). (5) HyBoost technologies are modular, meaning that economies of scale can be realised at component level by suppliers. (6) As demonstrated on the project, HyBoost technologies offer the scope for good real world fuel economy because downsizing, full load stoichiometric operation and exhaust energy recovery are effective at higher loads. (7) Vehicles equipped with HyBoost technologies have potential to fall below some of the incentivised CO2 thresholds shown, therefore adding to their market appeal. (8) The HyBoost system has reduced dependence on "commodity" materials such as Copper or Lithium (compared to a Full Hybrid) and precious metals (Compared to a Diesel with advanced after-treatment, or even a Fuel Cell); hence its success (and linked environmental benefit) is less vulnerable to fluctuating commodity prices, and its life-cycle environmental impact is potentially superior.
