Validation 1.b results of JRC tests

• Three vehicles tested (1 LDCV-Diesel 1
  PC-Diesel 1 PC- Petrol)
• Six drivability tests for each vehicle ( 2 Cold
  start, 4 Hot start) and each Gear Shift strategy
• All three vehicles have shown some difficulty to
  drive the low speed parts (10 km/h) with the 1st
  gear.
• There are several downshifts from 4th gear (even
  from 5th gear) to 0, soon followed by an upshifts
  to 2nd gear. These should be avoided (it is
  possible to go from 4th to 2nd gear and continue
  with 2nd gear).
• Like the previous 2 vehicles, the Diesel PC has
  confirmed no problem with accelerations and top
  speed of WLTC ver.4.
