| My '07 RDX with ~17000 miles on got 24.5 mpg driving 73 mph with the air running, on a mostly flat surface during a 700 mile round trip 95% highway last summer. Lately it has been averaging 20.9 with 50% city driving. Once summer is over, ethanol % is less, and resume to 30% city the mileage should return to average 22.5. These are all by the car readings, not by hand calculation. | |

On a recent trip to North Myrtle Beach from Frederick Md (450 miles 17.5 gal got 25.7 MPG) Yes this was manually calculated and I am positve about the number of gallons. Mostly highway (I95) till Wilson NC where backroads takeover. This was my driving. Around town, which for us is rural Carrol/Howard county, my wife consistently gets 22.5 to 23 MPG. This is also manually calculated. |

Replying to: Firebird_EOU (Sep 02, 2009 4:49 pm) Or even use Toyota's new HSD extended VVT-i technique to transition the engine from "Otto" mode into Miller cycle mode as the throttle opening rises. With the addition of DFI that would allow a 15:1 compression ratio for low engine loading, cruising, and transition to 10:1 to accumodate rising turbo boost with increasing throtte openings, acceleration or high enegine loads/loading. 35 MPG and 300HP.

Replying to: wwest (Sep 10, 2009 10:05 am) What's wrong with you? This isn't an 'engineer your own engine thread' Or a 'WIRE your wastegate open forum' Maybe you should spend some more time at your local community college, where your ideas can be exploited. Instead of suggesting people self destroy their $40,000 luxury vehicles! Good luck to you wwest! Stay away from open microwave ovens...

Replying to: flytldr (Oct 05, 2009 10:52 am) I'm comfortable, very much so, that anyone following my advice will have the knowledge to do so beyond the requirements of a community college.

Anyone got RDX MPG to report?

Replying to: steve_ (Oct 06, 2009 8:57 am) Isn't the CX-7 due out soon with a non-turbo I4...?? That will be a good point of comparison as to just how wasteful a factory turbocharged engine is, can be. |

Picked up a brand new 2010 RDX base 2WD in Atlanta last week and drove it directly Clearwater, FL. I was following a friend towing a jeep behind his truck so our speed never went much over 70. The highest the computer got to was 29.6 and the average, when getting home, was 28.4. I was really impressed. Don't know what it will be at my usual 75 to 80 mph highway driving. The city driving, which hasn't been much in this car this week, has lowered the computer mpg to 27.5. Still running on the gas purchased in Tifton, GA about 300 miles from Clearwater. Turned in my leased 07 MDX and even made $1300 on the lease. The car is for my wife, downsized for $$ reasons and purchased this time. Wife loves the RDX. Hooray! I like it too. Howard |
