4.1 Hybrid and GHG activities
None.

4.2 Assessment of powertrain testing
The Group finally agreed that powertrain testing be included both for validation of the HILS method and for testing a hybrid powertrain as an alternative to the HILS method.

4.3 Assessment of chassis dyno testing
There being no further input, it was agreed to take the final decision at the 16th HDH meeting. This decision would be presented to GRPE at the 68th session. It was also agreed that both HILS and powertrain testing would fit very well into the context of gtr n° 4, which is not the case for chassis dyno testing. This conclusion needs a detailed explanation in the final
report.
