Lexus es300h update

June 11, 2019

As I drive the car repeatedly over routine round trips, I am gradually forming some conclusions about its mileage performance.

1. Mileage is lousy when it is cold. Until it gets three miles from home, it uses from a bit over 9.0 L/100 km to as high as 12.0. A trip to Newboro to bail out the fishing boat, for example, starts at 9.1 and over the 14 mile round trip gradually reduces to an average while coming in the driveway of 5.8 L/100 km. That’s 48.7 Imperial miles per gallon, 41 U.S.

2. Starting while warm, the car maintained that same 5.8 L/100 km average throughout a trip to Kingston for shopping and back today, about 100 miles of heavily travelled two lane and a bit of four-lane highway and assorted city streets and parking lots.

3. From a cold start the trip to Rosebridge Manor in Easton’s Corners, a sixty-eight mile expedition over little-travelled roads and frequent hamlets with speed limits and stop signs, the average steadily decreases from a bit over 9 to a final average as I use battery power through Forfar, up Young’s Hill Road, and in our long driveway, of 5.1 L/100 km. Usually traffic allows me to poke along at 80 km/hr on this stretch, again with frequent coasts through villages on electric. That’s 55 miles per Imperial gallon, 46 U.S.
