Just received our RX400h - delighted with the improvements over the 2004 330x we had - much better acceleration, much tighter transmission. Electric takes a little getting used - especially when backing out of a parking spot as pedestrians are alarmed. Electric brakes are a little touchy. We are getting an overall 24.3 mpg on regular 60/40 city/highway and have 650 miles on the car. Gas engine seems to run much more than we expected and electic supplements gas when above 50 mph more than we were led to expect. Overall we are delighted with this vehicle. Exceptional quality inside and out.
Acceleration, Levinson stereo.
Transmission surges a little when heading up extended mountain roads, and batteries are seldom able to fully charge with the driving we do.
