I just purchased a CPO 2008 400h and I'm not impressed with the gas mileage. I'm averaging just under 23mpg. My take offs are very slow and I coast as often as I can. I am not a fast driver in fact people in the car with me have said they can see a nickle on the side of the road. I travel around 7 miles to work and 3 of those miles and on the interstate traveling less than 60mph. I run the AC only on the trip home. I am still on my first tank of gas and have put 230 miles on the vehicle and average mpg says 22.8. Any suggestions you all might have would be greatly appreciated. Thanks for your time.

I am averaging between 28 and 32 mpg, the shorter the distance travelled the lower will be your mpg. For a SUV of this size, weight and power no other SUV is even coming close to this low fuel consumption,i.e. my previous Explorers were averaging around 18 to 20 mpg. Nobody can beat physics, not even Lexus :)

Does the ABS system control the traction control too? I wonder if this would work to prevent loss of power to the wheels in the snow?

Do you happen to know where your mechanic accessed the circuit? Was it at the fuse box?

Does this cut power to the entire ABS system or just open the circuits for the input sensors?

I have to believe that cutting power to the entire ABS system would just turn the system OFF, whereas opening the circuits of the input sensors would be more beneficial, in a sense tricking the ABS system into thinking there's nothing triggering the sensors that there's rough terrain.

I will contact the guy who did the modification to get more details out of him. The latest he told me when I picked up the car was, that contrary to my previous statement he did not disconnect the 12V by means of a switch instead connected a switch in line with 1 ABS sensor. If one sensor "fails" ABS is disabled.

The way it works is quite simple. The ABS system kicks in to break the wheel once the tracking control detects (a) wheel(s) are loosing its grip, subsequently the car is loosing power. Once the ABS is disabled the wheel keeps on turning and power is still provided to carry on driving.
