rexmiami Posted September 20, 2005 Share Posted September 20, 2005 The following are the calculated figures for my 400h delivered on 6/3/05 Total Miles Driven = 7080 Gallons Used = 262.168 Total Cost = $691.41 MPG = 27.006 Average Price /Gallon = $2.61 Estimated 90% highway and 10% city. Includes one round trip Seattle to Lake Tahoe and five round trips Seattle to Portland. I use cruise control (set at posted speed limit) whenever it is safe to do so and the A/C is generally set at 74 degrees. Four tanks of premium, the balance 87 octane. About a 1/2 mpg increase with the premium. I always use major brands such as Chevron, Shell, and Union 76. No Safeway or Costco. I rarely punch the accelerator and coast when I see a red light in front of me. Observations: I am now averaging 29+ mpg on trips to Portland. The calculated mpg is about 1 mpg less that what the navigation screen shows. The city driving actually lowers my average mpg. Extended stop and go traffic causes the battery indicator to change to lavender which causes the ICE to run in order to charge the battery. Short trips before the ICE warms up average about 22 mpg per the navigation screen. My average mpg did show an increase after 5000 miles. I am averaging about 5-6 mpg better than on my 2003 RX-300.

rexmiami Posted September 20, 2005 Author Share Posted September 20, 2005 Did you drive your 300 the same way --- cruise control at speed limit ?? ← Yes, I drove it with cruise at posted limit. I did not intentially coast to the degree I am doing now which may account for a small amount of the mileage difference. The rest of my driving patterns are about the same.
