I do NOT recognise my RX400 from this: 58-plate owned from new.
Petrol consumption is 31mpg in summer and has fallen to 29 this winter which was exceptionally cold in Decemnber.
Range on battery power - over 4.5 miles. Just for a bit of fun when the car was new. Weather OK but autumn evening when traffic was light, mnaximum speed 25mph, not especially flat.
Cannot agree with your asertion in the slightest.
