800+ Mile Club

Nothing is certain but I think I will beat your record.



Seriously, congrats on you and the others 800 milers; quite an accomplishment!

 

what vehicle is that?

 

Mark,

If you ever find you need to replace your tires, may I recommend the Micheling Energy Saver A/S? LOL. Your mileage is awesome! Keep it up!

 

Volt.

 

Thanks! Hopefully new tires are a ways off. I'm at about 11600 right now.

 

Oh no!!!, he beat my record..., time to try harder!

 

.. and then there were four..





1,301.5km @ 43.6 liters ~ 3.35 l/100km
808.71 mi @ 11.52 gallons ~ 70.21 mpg

Here's my nutty attempt which i probably won't try to replicate anytime soon (who knows..?)
On my last tank, I purposely topped off about an extra .4 gallons to make sure that in case I have a calculated chance of doing 800miles, I want to make sure how far a set goal of 11.9gal (45liters) will take me.



At first I thought I'd ditch the whole objective when the usual schedule changed to make an extra trip 3x a week in morning to drop of my son at daycare. That usually meant sacrificing a bit more mpg in the morning run having to start the ICE again which haven't fully warmed up properly and also getting into the heart of peak rush hour and dropping off my wife at the train station which takes the ugly route. But nonetheless, I still gave it a shot and tried really hard without going too slow for comfort. Lucky for me the past week saw a bit light traffic due to the holiday season and warmer temps.

The only advantage I guess why i'm able to do this is having a solid tank where it's easier to estimate how long i've got (through SGII) and the flexibility to add a few extra liters.

The handicaps I had to live with are primarily the big (300-500ft) hills where I live, my non-LRR 205-width tires and 16-inch wheels, and also rush-hour traffic volume.

Home to work:



Work to home:


So set-up is the same: 2007 model with 70,000 miles, Forceum D850 205/50/16 Non-LRRs (42/40) on Volk TE37s, H&R springs, strut brace, chassis brace, thicker rear sway bar, TPMS, SGII (RPM, BTA, IGN, SOC), EBH (in the morning). Time of year: start of summer (25-30C), ran for about 50km (32miles) on blinking last pip.

Techniques are:
rain guards/deflectors, windows down 1-2 inches. open halfway when it's a crawl/stationary to let cooler air back in.
A/C off (95% of the time except when my son gets cranky already)
P&G,
light to moderate acceleration @ 13-16IGN (sometimes 18 when needed to hurry up).
using EV sparingly (max of 60 amps at max 3 sec burst)
never let SOC go below 50%
bleeding off speed uphill at constant pedal position keeping one eye on IGN and instant FE bar.
warp stealth and super highway mode.
battery assist (EV off) on some glides depending on SOC.
stop light anticipation and timing
knowing/scanning ahead which lanes flow faster to preserve momentum
driving with buffer

 

Congrats!

From the elevation change in your chart it looks like you are taking a different route/path from home to work than from work to home. Can you tell us why you are doing this - was there some fuel efficiency advantage for doing this? Thanks.

By the way .. How much warmer has been your driving temperature where you are down under?

 

Now your raised the bar so high I don't think I will ever be getting there!

Just kidding. That is sure a very good tank. Very nice.

 

Thanks, Walter. The reason for that is primarily to avoid the high toll charges on the harbour bridge which cost more than the fuel i use every day so i have to take the back route with the 500ft hill. Also I bring my wife to the train station in the morning which is halfway through the morning commute.

In the afternoon, i use the harbour bridge because it doesn't charge toll the opposite way.

In the past month, the weather was a bit unpredictable. Sometimes it would be around 21C (70F) then 32C (90F) the next day. But it's getting warmer and warmer. We've had a few showers also but wasn't on the road those times so wasn't affect much by it.

 

Thanks, man. Just wanted to check if our cars can still mix it up with GenIIIs. So yeah! It IS possible to do
800-mile tanks even on rush-hour daily hilly drives on GenIIs even with non-LRR tires ! So get on to it! chop chop! I mean glide glide!

 

You couldn't have done it in yours, not with our North American bladders....(that sounds funny)

 

Very nice!

 

Haha! Anybody want to sponsor nice LRRs?

I really wonder if the lightness did offset the frictional losses of a regular tire. If so, by how much?

 

yup, i still have the OE wheels and tires still pumped up. I'd have to take off one of the current and weigh them
both if i find the time to do so tomorrow.

 

ok, the OEM 15-inch wheel with 195/60/15 tires is 35 lbs
while the 16x7 TE37 with 205/50/16 tires is 32lbs.
The wheel itself is 11.2 lbs. Not sure about the OEM wheel.
