Let me begin by saying I am a big fan of TM and a reservation holder. I have no doubt the “S” will be an amazing car and a game changer for the auto industry.
My big concern is the economics of battery replacement. TM, by law, has to make (available) OEM parts for at least 10 years. However, there is no guarantee that these batteries will be better or cheaper – only available.
Batteries will evolve: range and power will increase, while weight, size, charging, and price will probably decrease. Newer models will reflect these advancements. Where will this leave us early adapters? Many forum readers ASSUME they can switch out their ‘old’ batteries in the future for an 85Kwh+ new battery for a fraction of today’s battery price. This may or may not be true or possible.
The bottom line. We may hope and assume that these advancement will positively benefit us… but there is no guarantee. I don’t want to find out in 8+ years an 85Kwh replacement battery will be $50K but a 125Kwh generation II battery is $25K. I understand TM has to move onwards and upwards,. I need to know where I stand… down the road. Obviously, TM does not have a crystal ball but they can give us a guarantee that future batteries will be compatible at a competitive price.
My questions are:
1. Will new technology advancements be compatible with our early “S and X?
2. Will replacement batteries reflect both the newer technology and better pricing?
3. TM Battery Warranty. Will I get a new battery, with a new warranty, or a pro-rata adjustment?
It is important to me to know up front how TM will address these concerns. This to me is a deal breaker, not cup holders or center console.
