Did you notice they were driving at 65 and said the range was not 265 but close to 240? But the claimed range is based on 55 mph driving so I would say 265 is easily possible. And this sounded like real world driving with braking and speedups and slowdowns like we all experience in our normal drives. So for those of us in less populated areas should be able to get very close to 300 miles if not more.
The performance numbers are even better than InsideLine's.
Nice article. For the 85 kWh version, I guess this means we drive slower than the rest of traffic for most of a trip or limit the planning to about 200 miles before stopping to charge.
I'm not too pleased with the comment about the seats not being comfortable enough for long drives, though. Will I have to buy seat cushions for everyone for long drives?
The range for driving 55mph is supposed to be 300 miles. The 265 mile range is based on EPA new test method which is a mix of different conditions. So the range test result is a little bit disappointing. The author seems to suggest that because of the need to do more rapid accelerations to pass slower cars on the way,the resulting range is shorter. I wonder if the standard 85kWh version (non-performance) would fair better.
It shouldn't matter whether the car is a 85 kwh performance or normal as far as range unless you are putting your foot into the accelerator.
@EdG - remember this is Elon's car so probably doesn't have the full production interior. Hopefully the seats in our cars won't be as bad.
They also don't mention if they actually charged the battery for the extended range or f they did a standard charge. I assume they would have done extended but I wish they had stated so.
A lot of us have ordered the 60 kWh battery. I wonder when specs and reviews will be available for it. Everything so far has been for the 85 kWr unit and usually the performance model.
As discussed at http://www.teslamotors.com/forum/forums/optimal-speed, the car should theoretically have gone near 300 miles when driving at a constant 60-65 miles per hour with no headwind.
So either (1) the tires are vastly less efficient than they should be or (2) there's something wrong with the model or (3) hilly terrain caused a lot of braking on the down slopes needing makeup power on the ups or (4) the driver wasn't close to doing steady speeds for the trip.
If the car was driven for several miles behind someone going closer to 50 mph, the range would have increased due to less aerodynamic friction.
Is this a hilly course? Could he have been riding the brakes downhill for much of the way?
I thought the test driver (author) was very savvy. His partner asked "are you on the brakes?" when they felt the deceleration; he answered no, it was regen. Also they said the car was charged on "range" mode.
Of course they also lamented they chose to do a lap around a test track on the way..... lol we would all be temped to do stuff like that, and they admitted that certainly cost some range. But what heck, this is real world driving by motorheads.
If you wanted to an eco demo you would surely have achieved better range. But this struck me as validation and vindication that real drivers in real conditions having fun with a sport sedan can actually get 230+ miles of highway driving. Works for me.
The tires was Michelin Pilot Sport PS2 instead oc the Continentals. Those tires are as far from LRR as possible.
Also, I think they only charged in Standard mode.
EdG, Not the correct link for the numbers. Please use the blog http://www.teslamotors.com/blog/model-s-efficiency-and-range to find the correct numbers. Per that graph they were reasonably close to predicted.
jkirkebo and pilotSteve -
I don't think there is a definitive statement of whether they charged in 'range' or 'standard'. They acknowledge that there is a 'extended range' charge option, but when they actually talk about recharging the vehicle, they do not mention which one they chose. And they don't mention this again the rest of the article.
It would make a big difference to know which one they did choose, of course. Hopefully they inform their readers of this at some point.
Bottom line is that they loved the car and gave it a very enthusiastic review. They had more time with the car than any of the other reviews that I have seen so far. The Model S continues to achieve superlatives everywhere. I'm very excited.
Isn't the performance (P85) model less effective on range. I have always heard that Tesla went all-in on performance for the P version at the expense of range.
So the Base 85kWh model could do more I assume
I was told that the 21" performance tires would take about 5% off the range. I don't recall what tires were on that test car, but I seem to recall it had 21" wheels.
I believe Tesla states... If driven the same, battery life is equal in both 85 and p85.
They should be the same except for tires in terms of range assuming you don't gun it all the time in p model. I think the review was spot on. I don't want an ideal range scenario because it wouldn't be as useful to me. It means it's all the more important to get the biggest battery you can unless you want to be super careful when you drive to get long ranges. I'm going to be having fun with the performance and this seems to be the range I'll get.
I liked the review. I real world range test drive.
As discussed at http://www.teslamotors.com/forum/forums/optimal-speed, the car should theoretically have gone near 300 miles when driving at a constant 60-65 miles per hour with no headwind. (EdG)
They did have some headwind:
"The passing tree tops were noticeably stirring and the occasional flag was pointing at us at three-quarter headwind angles."
The Tesla efficiency graph shows that on perfectly flat roads maintaining a constant speed of 75mph you would get pretty much exactly the range they did. When you add in varying speed, traffic, up and down hills, climate control, etc -- I think their result was exactly as expected -- at least exactly what I expect to get when I get mine.
I get about 76mi range (extrapolated) on my LEAF, driving half of my commute at 80mph on the interstate, and if I were to drive totally on the interstate, I would expect to get about 55mi range. I can easily add 20mi to my range just by driving 60mph on the interstate (though I fear for my life doing that in ATL :). If I drive surface roads that are 40-45mph with few lights, I can easily get well over the nominal 100mi range.
So, I see the Tesla as performing about the same -- I would expect to get about the EPA's 265mi range with a mix of highway and surface roads (just as in their test), and I expect to get 200-225 on mostly interstate trips depending on how fast I drive.
Overall, the article confirmed my expectations. I suspect some people who haven't driven an EV or paid attention to how much their driving style affects their gas mileage in an ICE (when I had a Turbo MR2, I could get anywhere from 17-33mpg depending on how I drove) might be alarmed by the result, but once you get used to the car you know exactly how it is going to perform given how you drive it, and you just don't think about it at all unless you are doing something out of the ordinary.
"Calculating range, taking into account topography (among other factors)"
If we knew their actual route we could check with this tool...
If we knew their actual route we could check with this tool...\
A guess based off the image with a map and it's range was 240 miles. (the map's image also had range 55-69 on I-15) Lots of hills on I-15.
If we knew their actual route we could check with this tool...\
The article says " Using Tesla's home charger (240 volts at 80 amps) a full extended-range battery refill requires 6 hours (4 hours for standard-range recharge)."
Where are these ranges explained? I don't recall seeing them on the website.
txjak, I think this is it.
Sudre, I don't see any reference to these terms. which tab did you find them under?
It seems to me that the 80 amp charger should replenish at 62mph and be able to provide 300 miles in 4.8 hours, not 6 hours. 4 hours at the 62mph rate should provide 248 miles of range.
I'd still like to know what the terms extended-range and standard-range are supposed to mean.
The Model S has two charging levels, Standard and Max Range. The selection between the two is made on the charge settings screen on the touchscreen. This screen is displayed anytime the charge port door is open or by touching the battery icon on the top of the touchscreen.
The recommended charge level to use for daily operation is Standard. In Standard the battery is charged to 85% of its full capacity. (Note that the current version of the Guide for Owners incorrectly states that Standard level charges to 90% of full battery capacity.) To achieve maximum driving range, Max Range level charges the battery to 100% of its full capacity. The Guide for Owners cautions not to use Max Range frequently because it reduces the life of the battery.
Rod and Barbara: What has been your experience with range?
@ cerjor – To start with we haven’t made any long road trips. We’ve driven 950 miles since we got our car and our cum efficiency for that time is 339 Wh/Mile. You can turn this efficiency into a max range if you know the Wh available in the battery (see our recent post on Rated Miles and Predicted Miles for more on this issue). For now, let’s assume 84 kWh are available and then our cum efficiency predicts a max range of 248 miles. On one charge-to-charge cycle we drove 81 miles between charges averaging 315 Wh/Mile during that time. This corresponds to a max range of 267 miles. My wife really likes to drive the car carefully in an effort to maximize the efficiency. On one 30-mile trip, which included freeway driving at 55 to 60 mph, she used about 260 Wh/Mile. This corresponds to a max range of 323 miles. On the other end of the spectrum, we had 48-mile charge-to-charge cycle that used 391 Wh/Mile. This corresponds to a max range of 215 miles. So, in summary, our experience so far indicates max range can vary from 215 to 323 miles and our cum average has been 248 miles.
@ Rod and Barbra - Thanks so much for your posts. It is nice to see some real information. Range looks like about what I expected.
