Interesting: look at the improvements over each test run.
However, the fuel economy values for the test truck on the baseline test (no Jetstar) against the final test (with Jetstar) in each of the three test segments are shown in the attached table.
Test Run Average MPG Average MPG
(without Jetstar(TM)) (with Jetstar(TM))
1 7.96 8.49 = 6.66%
2 7.62 8.46 = 11.02%
3 7.45 8.52 = 14.36%
Seems the longer the unit runs the better it gets.
Wonder what the JetStar could do on a long run?
