Battery Range - Performance in the Real World

Battery Range - Performance in the Real World

I need some help/input from the “Forum.” Perhaps Roadster owners can advise me from their hands on experience. I am trying to decide between the 160 or 230 mile range battery.

1. Am I correct, the Roadster and ‘S’ batteries are roughly the same?
2. The factory uses the 245 mile range for the Roadster. What is your real world mileage range in daily driving?
3. After a couple of years what percentage decrease in range and performance have you experienced?

Also, I understand the faster I drive and the more accessories I use will reduce the range. I am not a racer but I do enjoy a spirited drive. I will likely have the air conditioner or heater, audio, and other accessories on. The 160 range battery will satisfy 80% of my daily driving needs but if the real world range and age degrade the actual range to under 120, I may need to step up to the 230.

Thanks for your help.

If you think I cost you $10k, just wait 'til you see the tasty options they're going to entice us with. :-o

Some friend you turn out to be! Can't wait.

Mycroft I hope you realize my comment was tongue in cheek :-)

I have had an opportunity to speak with one roadster owner while he was getting his car serviced. In short it performs as advertised. Additionally he said the program that monitors usage and informs you about remaining range is extremely accurate. He was very pleased with the over all performance of his vehicle.

I think we are / will be very fortunate to have Mr Musk as a CEO. It appears that his paradigm is under promise and slightly over deliver. I think that is an excellent business model in general.

The question I have is, what are aerodynamic tires? There has been some speculation but nothing from tesla other than Mr Holzhausen supposedly saying, paraphrased ( the tires are not too unattractive)

For me I'm getting the 300mile ( potentially now 320) battery pack so I can take some trips and because it makes it easier to keep the battery within a window (of charge) that optimizes longevity.

Oh yes thank you Mr Volker, that is exactly what I meant. The purpose however of my diatribe was to say at the end of the day, if we are to be early adopters we need not only to understand the risks involved but also understand the motives of both individuals and industries that are respectively afraid and financially opposed to change.

"Mycroft I hope you realize my comment was tongue in cheek :-)"

Certainly. :)

"I think we are / will be very fortunate to have Mr Musk as a CEO. It appears that his paradigm is under promise and slightly over deliver. I think that is an excellent business model in general."

I agree 100% Contrast that with the mind-blowing ineptitude of Fisker!!!

"The question I have is, what are aerodynamic tires? There has been some speculation but nothing from tesla other than Mr Holzhausen supposedly saying, paraphrased ( the tires are not too unattractive)"

It isn't the tires that are aerodynamic, it's the wheels. We have no idea what they're going to look like.

I'm getting the 300 mile pack as well (with the Signature Edition). Primarily because that's required for the Performance package. Without that, I could easily get by with the 230 mile one.

0-60 in 4.4 silent seconds WILL BE MINE!!!

I don't know more than you do, but thinking about it I assume that aerodynamic wheels means covered rims/no (visible) spokes. Look what some racing bicycles have. If it wasn't for a particulary innovative design (which Tesla no doubt has in the desk) that would certainly look, um, unconventional. But a flat/plane outer surface would probably help aerodynamics.

You lost me at paradigm.

From what I read , I thought there was a more efficient wheel design in the works.

Perhaps the easiest and most cost effective way to boost mileage is to overinflate, skinnier tires. I doubt you will be pleased with the handling or braking in fast turns, especially in the rain.

Just kidding!

Mycroft | November 7, 2011

Not sure if you're kidding petero, but in this case, "paradigm" would equate to "world-view", or in the German, weltanschauung.

Elon likes to actually deliver more than he promises, hopefully earlier than promised. Henrik on the other hand does the exact opposite.

As Volker said, the best guesses we have on the new wheel design is that it would be flat with colored or engraved accents of some kind.

Anyone seen Zelaza lately?
I think it is best we warn new readers for his contrinutioms, when he is back with a new name!

Leofingal | November 7, 2011

Did a quick web check, and Zelaza actually means Iron (Fe) and not oil or petroleum...

We own a towing company [...] It would be great if they have the eyelt behind the bumper with the removable peice to hide it but none of the pictures Ive seen show it. Since Ive already had to tow my wifes S550 for running out of gas Im positive I will have to get her for not charging the Tesla LOL (Towman26)

Not necessarily:

Mycroft;
You sound like the type who will turn off TC and loudly burn rubber, actually!

>:p

gjunky | November 8, 2011

I still wonder why you would tow a car that is out of gas. Wouldn't it be easier just to put some gas in? :)

Slightly off track. I believe Ford is using the new Michelin Energy Saver A/S tire on their new Focus EV. I doubt Tesla will go with this specific tire as they will likely be stressing performance over other considerations. But it might shed a sliver of light on the wheel/tire/320 debate( ?)

Michelin claims:
Energy Saver Construction combined with the use of a special type of tread rubber keeps the tire running cooler, increasing fuel efficiency & reducing CO2 emissions. (I assume this ICE oriented)

MaxTouch Construction™ maximizes tire contact with the road & evenly distributes forces of acceleration, braking and cornering resulting in longer wear-life.

Advanced silica tread compound provides all-season traction and no-compromise wet braking.

I was reading up on the upcoming release (Dec. 2011) of the Ford Focus Electric (100 mile range) which is Ford’s answer to the Nissan Leaf with ‘only’ a $40K MSRP! Ford is also releasing their small truck-van Transit Connect Electric with the same battery-motor as the Focus.

Mycroft and friends.

I understood the definition of paradigm. My remark was a commentary on the high level of intelligence that is exhibited on the Forum.

There are a number of brilliant people on the Forum. Makes sense, a state of the art EV would attract this caliber of audience. I am reasonably smart , but many of you are ‘rocket scientists. ‘ I am very impressed. What I am saying is it feels good knowing smarter people feel the same way I do about the “S” – I think.
