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.

Rare Rides Icons: The Lincoln Mark Series Cars, Feeling Continental (Part XLII)

The Truth About Cars

There were simply fewer coupe buyers as Americans ran to minivans and the earliest family-friendly SUVs. It had been quite some time (1979) since any Mark used its own platform, and in that instance it was only because the Thunderbird had moved to a new platform via downsizing. Only trim remained to tell them apart. And that was all.

Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power. Earlier post.) displacements, said Redon. Earlier post.).

NRC report finds significant number of near-term technologies could greatly reduce fuel consumption in passenger cars

Green Car Congress

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.
