Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. However, prior to the remarks on climate change and the regulatory response, he spent a few minutes discussing the efforts on urban pollution—e.g.,

This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. The WLTP is significantly more dynamic with faster acceleration rates.

Thrust 1 builds on the significant amount of work carried out over the past several decades, focused on building advanced boosted, downsized, and downspeeded spark ignition engines. High combustion noise and high HC and CO emissions are also a problem, with lower exhaust temperatures representing a challenge for current emissions controls.
