Mine's a non-s, 2012. It's pretty easy for me to hit 500 since I travel a lot of rural roads for work (55 mph) but all of my driving includes some city and highway driving. When I really try I can hit 600...I've done it twice. My best was 635 miles in Michigan's Upper Peninsula, driving from the Mackinac Bridge to Copper Harbor and back...which at the time was 55 mph. For that one I just put it on cruise at 60, had the windows and sunroof opened, and just enjoyed the views of Lake Michigan and Lake Superior.

 

Wow you guys are amazing. I will have to try one week to see what I can do. Will need to factor in more time for my commute..I usually average around 80ish...

maybe my new diffuser will help with aero

 

Just had a 501.4 mile tank with 57 miles left on the computer. 40.4 mpg. Mix of highway, rural, and city.

 

I'm starting to believe the 500mile club is an absolute myth or you guys coast downhill for 100miles out of those 500.

Last time I got gas something weird happened and the fuel hose did not fully stop (fuel spilled a bit) so I knew the tank was 100pct full. Thus, I decided to test my stock (engine) 6MT 2012 MCS during about two regular weeks: 90% highway at around 75-80mph and some suburban driving around 20-40mph. The last two days I started to coast here and there, no spirited driving and and was generally super conscious about fuel consumption.

Results: I achieved 404 and computer consistently said I had about 3miles left. Let's assume I could have reached 410 (by the way, the gas light was on for about 60mi). Then I filled up fully and pump said 14.2 gallons. Which sounds about right from some of the threads here about tank capacity.

500 miles: no way. I guess it would need to be the base version, automatic and one has to cruise at 55-60mph to achieve that. And quite frankly, this car wants to be revved, especially the 6MT. I won't try again and I still don't believe any of you!

 

I didn't think anybody every visited this thread anymore! I have a base 2012 R-56 6MT with 120,000 miles on it and I can hit 500 miles very easily. I've even had two tanks over 600 miles. If you look back you can see I had one 635 mile tank, but it was in Michigan's Upper Peninsula driving 60 miles an hour from the Mackinac Bridge to Copper Harbor and back to the Mackinac Bridge before filling up. I've had the car since it was brand new and have kept it well-maintained, so it still runs like a top. Not every tank is a 500 miler since sometimes I'm in a hurry or sometimes it's more city driving. I do drive on a lot of rural roads for my job, so that helps keep the mileage up.

 

I just spent the last 4 days hypermiling my R56S to see if 500 miles on a tank was possible in real-world conditions - i.e. my commute and whatever random trips to the taqueria, grocery store, etc. I typically get 425 or so miles on a tank so I figured it should be possible. A bit of mental math 500 miles / 13 gallons = 38.x provided a target mpg.

My commute is about 25 miles, about 20 of that highway with traffic - sometimes flowing, sometimes jammed up. The rest is local streets with stop signs, traffic lights, etc. It isn't flat either, the highway has rolling hills and I live up on a hill with a 25mph speed limit. Long term I have been averaging 31.1mpg. Techniques were the basics: slow down on the highway to 65 on cruise control; keep RPM as low as possible, often skipping gears when shifting; accelerate as slowly as possible and try to never use the brake; coast where possible. Basically driving like there's an eggshell between my right foot and the accelerator.

Results: After about 230 miles of this, the long term average is 38.8 mpg, a 24.7% increase. I started this about half way through a tank, when I filled up this morning I was at 470 miles with a predicted range of 20 miles. If I had started a few days earlier I would have hit 500 no problem. After putting 13.7 gallons in the car, the predicted range was 550 miles. I learned a few things:

1) It's hard to drive like it's a Prius instead of a MINI! No fun at all.
2) It's BORING. I spent a lot of time in the right lane.
3) Waiting at stop lights will kill your average. I always hated the auto start-stop systems but I have to admit that it helps.
4) It's amazingly effective! A nearly 25% improvement is significant.

Maybe if I get really bored I'll put in the necessary 500 miles to prove it can be done, for now I'm satisfied with the proof of concept results and the math to know that it is possible.

 

Back in the club again.

Drove my mother from the SF Bay Area up to the Oregon border. Basically set the cruise at (or maybe just above, shhh!) the speed limit. Was at 495 miles when I hit two "carrots" left and got the low fuel message. I skipped the next gas station I saw because it was still (just) below 500, and filled at the next. 502 miles at 39.7 MPG.

I'll take it.

 

Just under 515 miles this tank! In large part, that was due to much of it being the trip back from near the OR border. I lost a decent amount of altitude getting back to the Bay, which helped. But once back here, it was back to shorter trips with more starting and stopping, which hurt the efficiency.

Slightly lower MPG, but it took me a little longer to get to the station.

Now he goes back into hibernation for a while.
