EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

Further, there is increasing interest among stakeholders in exploring the benefits of higher octane fuels that would lead to higher compression ratios which would lead to more efficient engines and reduced fuel consumption. One significant trend is engine downsizing coupled with turbocharging. Source: U.S. Click to enlarge.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. Source: Borgwarner. Click to enlarge.
