It helps enough that the hydrocarbon capture system and excessive warm-up to hybrid mode was not needed in the NHW20 model. I have an NHW11, 2001-03, and it won't go into hybrid mode until the coolant is at 70C. This requires careful, neighborhood driving for the first 1-2 miles. BTW, the block heater is very popular with the NHW20 owners.
