The NAIAS wasn't as accommodating as Alan hoped, but sometimes e-mail can fit the bill. A few of us on the forum had a number of questions that we collected and hoped to get answered at the NAIAS forum, but the forum member that attended didn't get useful answers. I figure it's worth giving it a shot through the official channels. 1. Interior - When do we expect to see an unveiling of interior updates? More specifically, the latest that I've seen is the Betas from October and am hoping for some newer pictures or videos on the progress. Even some sketches indicating the types of changes expected relative to the Beta would be greatly appreciated. 2. Active Air Suspension - When should we expect more formal information to be published about the height settings available, and so forth. The information has been somewhat vague on these points thus far. "Does the air suspension keep the car level with hard cornering?" 3. Seat adjustments - Which dimensions are adjustable for 8-way and 12-way? 4. Battery upgrades - Is Tesla planning to offer these to customers, or working with a 3rd party (specification process, etc.)? Should we expect that only warranty-replacement batteries will be available until 2014 (or later)? Will a vehicle purchased with a 40 kWh battery be upgradable to an 85 kWh battery in a few years, and will the performance (0-60) improve as a result? When the technology advances will larger batteries (170 kWh) be compatible with the Model S? 5. Warranty - Warranty coverage (and option?) information for more than the battery would be appreciated. Also, in what situations is the ranger fee waived? 6. Phone app - What kind of data package is needed to let the iPhone app show you the car's condition? Or can it be done by having the car hook into your WiFi network at home? Will a Windows Phone 7 application be offered? Android? 7. Navigation - Will the car be able to store maps you download at home for later use? If yes, is this part of the Tech Package or in the base offering? 8. Design Studio - When is the full reveal of Model S Design Studio scheduled? Some believe February 9th in conjunction with the Model X introduction. 9. Width - Is the Options & Pricing page width dimension accurate? The width is significantly less than previously published, and some of curious why. 10. Battery Degradation - "Is the life of the battery pack pretty much the same for all versions - approximately 10 years - or will the 300 pack last 15 years compared to say 10 years for the 40 pack?" (The original question was pretty vague so perhaps adding "for typical use" or "for 30-60% daily battery use" would help narrow the question.) 11. Front license plate - For states that require front license plates, some of us are concerned. We don't want to drill ugly holes into the front of our beautiful new vehicles. We don't want to sacrifice the aerodynamics or the aesthetics either. Will there be a recommended / supported way of addressing this concern? Will there be tow points available (many of the no-drill offerings for other vehicles make use of the tow points)? For those of us that want to discuss the topic with our state officials, can Tesla offer any specifics on the aerodynamic cost/impact of mounting the front license plate? 12. Electrical protection - "Would like to know if there is any protection from power spikes or lightning as the Leaf does [video @ http://www.nissan-zeroemission.com/EN/LEAF/quality.html]. 13. Tires - Tire manufacturers and model numbers would be appreciated. Will we have options to choose from or just 1 choice for each of the four wheel choices? 14. Wheels - What is the difference between the 21" and the 21" Performance wheels? The latter looks darker in the picture, but there's no documentation of the difference. 15. Extra wheels - What is the cost of an extra set of wheels? (Some of us are considering getting a set for winter tires.) Presumably it's some base price + extra for Aero or 21", but it's unclear what that base price will be. 16. Downgrading Sig - When "downgrading" from 21" to 19", choosing non-Multicoat, etc. the current "Options & Pricing" shows there's no credit for the downgrade. Is that firm, or is Tesla still considering this detail? 17. Tech - Blind Spot Notification. Adaptive Speed Control. Heads up display. Etc. There are a number of technologies like this that are available on some competitor luxury models. I'm presuming none of these are available on the Model S produced in 2012. Nonetheless, when should we expect more details on what is standard (like perhaps "regular" cruise control, for example)? Edit: I always forget something...
