Re: 74 miles on a single charge?

You can probably do it, but...have a contingency plan. Locate any public charging available on your route, and plan ahead using Tony's range chart. Note how many bars you should have when you are passing public charging, and if you don't have as many bars as you calculated, or the miles per kWh you're getting is lower than you figured on, stop and charge the car! Even 30 min or and hour could easily make the difference between getting home or getting towed.

I agree 100%. Unfortunately, the efficiency meter in the LEAF will indicate much lower efficiency in cold weather, even though it's not real.

He's doing 50 miles at highway speed and the rest at 35MPH limit. He's not going to be driving 65MPH the whole trip.

In southern NH I find a trip of 50 miles of interstate at 65 mph and 15 miles rural averaging about 40 mph is cutting it close. This is with no heat and no A/C, although I did have the lights on. To be safe I'd suggest looking at non-interstate options. I've done 85 miles of non-interstate with a max of 55 mph and I took it easy the last 10 miles. That trip was with lights and wipers for part of the trip. Both trips were late-April/early-May. Bottom line, the slower you go the farther you, but it costs you time.

Well, we had those variations in Phoenix with cars all at the same (warm) temperature. But, yes, the temperature affects Gid count (value goes up with cold while the battery clearly does NOT have more capacity) as well as meters associated with that data.

Take it from a guy who does 72 miles everyday here in DFW. It can be easily done. Just find a truck, the bigger the better, but even a large SUV or pickup truck would do and draft behind it by about 3 car lengths. You can actually go at speeds excessive of 70+ mph and hit efficiency of 4.3. At that efficiency going 74 miles is piece of cake, of course without climate control ON.

Or as my favorite Kollywood actor, Rajnikanth, would say, 'jujubie'. :-)

SaveOurPlanet wrote:Hello everyone,

I already asked the following question in the Newbies section already, and there were no replies yet, I figured probably because the question was buried deeply in the rental car thread. So I hope it's ok that I post it here again, as it is the "range" subforum - otherwise, dear moderator, just delete this post. :)



It's 74 miles from the dealership in Massachusetts where I will rent the Leaf to my final destination. 50 miles of that is highway - the rest rural roads with maybe 35mph of a speed limit - will I be able to make it on a full charge, or do I have to stop along the way and top up? The dealership said the Nissan Leaf will be fully charged at pickup, and there also are no plans to drive around further for a while once arriving at the final destination, so it's okay to arrive with a nearly empty battery.

I read a lot about range, like Paul Scott gets 100 miles on a full charge, and there is the range chart here on the forum with also seems to indicate that the 74 miles are doable. Then again, there is this thread here "The Dealer told me not to buy a Leaf", and there people are saying it might even not be possible to do 80 miles in a day, even with recharging.

In my case, it will be June, so it's not going to be freezing. Still, maybe light AC use will be nice (which takes some extra energy, it can also be turned off for a while), and New England is a little hilly, which could cost some range, and the car will be loaded with 2 passengers, still eco mode can be permanently switched on - will 74 miles on a single full charge be possible?

Thanks for any replies,
best regards,
SaveOurPlanet

keep in mind, everything affects range so if its raining, slow down. extreme heat requiring extra A/C, slow it down, hills or elevation change, slow it down.

keep your highway speed at no more than 60 mph. the extra 10 minutes is nothing compared to the inconvenience of being a mile short of your destination.

FYI; i drive nearly that distance frequently. i travel to client locations for work and frequently take the company car which is a 56 mile RT from my home. add detours, meals, rides for co-workers, etc and I am at that range all the time.

I have a GID meter which allows me to extrapolate my range. I toss in a buffer (usually 15 GID) and adjust my speed to fit my needs. the SOC on the LEAF is supposed to be fairly accurate so I would google map your route for distance, then reset a trip meter and compute your distance after about 20 miles of your trip then adjust your speed. drive another 20 and recalculate your range and adjust accordingly.

there is a lot of resistance for people driving slower than the posted maximum speed and that is simply sad. I strongly suggest you reduce your level of entitlement if a lower speed is necessary. as long as you stay out of the left lane, you should be fine.

However, I do find that the cold does significantly impact my Mi/kWh. In the summer, I was able to easily bang out 4.5 mi/kwh on my commute to and from work. In the winter, I struggle to get above 3.5. Same car, same route, same driver.
Do you use the heater? If so, that explains the difference.

Tony; you are wrong. I see a 1+ mile per kwh difference from Winter to Summer based on temperature alone. its rare but we get dry clear days in Winter here and I dont struggle to get 4 miles per kwh in Winter but only because I drive 55

but in Summer I am 4.7-5.2 miles per kwh driving 60 mph with A/C and not once or twice but SEVERAL times.

so temperature does matter

There is a whole website dedicated to 55 mph, along with lot of data and driving tips and tricks. Apparently, some people recommend this for gas burners too, because of the dramatic impact on fuel economy. For someone who has essentially grown up driving on the autobahn, it's a bitter pill to swallow, but I did try to drive the Smart diesel I rented in Munich in this fashion. The results were remarkable: the fuel gauge barely moved after 110 km, and it took less then couple of liters to top off the car.

i never drove the Prius that slow, but did drive 60-62 and averaged near 55 mpg in Summer when everyone else was whining because they were getting 42-43 and could not figure out why... its all basic physics.

every mph above 60 really takes a toll. every mph below 60 really gives a lot of benefit. as for me? I MUCH rather drive 55 on a 3 lane freeway getting home 10 minutes later and GET HOME!
