Variable valve timing is desirable for demonstrated improvements in fuel-efficiency, torque, and emissions; however, LaunchPoint says, currently available variable valve timing mechanisms are either too costly or far less effective and robust than desired. Valves of this type can be applied to a wide variety of internal combustion engines.

The divergence of real-world CO 2 emissions vs. manufacturers’ type-approval (100%) in Europe from various on-road data sources. However, the NEDC was not originally designed to measure fuel consumption or CO 2 emissions, and some features of the test procedure can be exploited to influence test results for those values.

A review of 43 studies of the effects of E15 (15% ethanol blends) on Model Year 2001 and newer cars by the National Renewable Energy Laboratory (NREL) found that the studies reviewed showed no meaningful differences between E15 and E10 in any performance category. The NREL team reviewed 5 studies in this area.
