_tjp_ Posted December 6, 2005 Share Posted December 6, 2005 I just did a test drive of the IS350 this weekend. Must say that I am very impressed with the car. Very solid and stable feel. Don't have to say that it was f-a-s-t.... I have a few of questions that I hope someone here can answer. 1. Since the test drive I have discovered that the ECT switch effects power. But, can anyone tell me how it does this? What does ECT stand for? 2. Next to the ECT switch was a Trac switch. I haven't been able to determine what this does. 3. What has been your MPG with your car? I am hoping the IS350 can get better mileage than the G35 that I am also considering. Thanks Quote Link to comment Share on other sites More sharing options...

Thanks ← When my car had about 1000 miles on it, I got over 27 MPG for two tanks on the interstate. Local driving I got 22.7 on the most recent tank. That's about half city and half mountain road driving.

Sirconrad Posted December 6, 2005 Share Posted December 6, 2005 The G35 gets really bad gas milage, My 350Z has the same engine and I average only 18mpg. Quote Link to comment Share on other sites More sharing options...
bartkat Posted December 6, 2005 Share Posted December 6, 2005 I think the IS350 will get the rated 28MPG highway at 70-75 MPH cruise control, in good weather. :D Quote Link to comment Share on other sites More sharing options...
Aija Posted December 8, 2005 Share Posted December 8, 2005 lol my lexus es330 is suppose to give me "21MPG" city and "28MPG" in highway.... in reality, i get 16.5 in city, 22 in Highway....i guess they really did design this car for 55year olds=p im assuming IS also would give lower gas mileage as well. When i drove it, the lag in shifting still exists (hence i think it affects the gas milage) Quote Link to comment Share on other sites More sharing options...
steviej Posted December 8, 2005 Share Posted December 8, 2005 mileage ratings are "suggested" by the manufacturer and are based on optimal conditions. steviej Quote Link to comment Share on other sites More sharing options...
bartkat Posted December 8, 2005 Share Posted December 8, 2005 Of the 5 cars I've owned in the last 10 years, all met or exceeded the EPA estimated mileage. Quote Link to comment Share on other sites More sharing options...
