2. Result of Validation 1b by India and JRC
India Dynamic concerns (difficult to follow the cycle)

PMR concerns (Vehicles of 35 to 65 kW/t have difficulty) 780-804, 1165-1210, 1180-1250, 1530-1740
Difficult to follow the lower speeds of 10km/h
JRC Observed difficulty to drive the low speed parts (~10 km/h) with
the 1st gear With typical European vehicles, there seems to be few problem
to follow the trace (accelerations and top speed portions of WLTC ver.4).

4. Proposed cycle modification for Validation 2
As a first step to move forward to validation 2, Japan propose to modify the following items (15 portions).the minimum speed set to 12km/hSmoothing to improve repeatabilitySet vehicle speed one decimal point
Other 16 remaining portions regarding dynamic concerns which was indicated by India and Japan should be considered during Validation 2.
