Upgrade limits?

Upgrade limits?

Ever since it was announced the Roadster would be upgraded I have been wondering about a couple of things. I am very happy with the updates announced for the Roadster, but I am still wondering about the items below. Anyone know the answers?

If Tesla made a lighter pack to achieve 50-50 weight distribution in the Roadster would they need to make a lot of modifications to the traction control and other systems in the car? Would any countries require crash testing the vehicle again?

This doesn't mention supercharger capability, but I assume the hurdles to overcome there are the PEM and the connectors. I assume an adapter could be made. I wonder if a new PEM could ever pay for itself or if that will have to wait for a future revision when maybe it could be shared with a new Roadster design. I guess the question here is how many engineering, testing and maintenance hours does something like a PEM upgrade need? Will it ever be worthwhile for the older model? If it is too expensive an upgrade few existing owners will buy it.

Same weight, 70 kWh.
No supercharging; wiring and interface changes to extensive.

I agree that direct current supply to Roadsters is not likely to ever be available. However, it would be very useful for a Roadster to be able to utilize one of the slots at a SC to get 100 amps at 250 volts, AC. That would provide about a 50% boost in about an hour and a half.

typo: too extensive

Yes, assuming the rectifier can handle it.

This upgrade "makes concrete" and frames a few future goals very well for the company. Provides neat data useful in projecting forward to future designs/goals/specs in other variants/models...from both tech and econ. perspective.

Well done/doing.

F I love Tesla.

Is that the official Tesla word, no supercharging with the upgrade?

The Roadster would be even more fun if weight is reduced. As an Elise owner I am very much impressed with the Roadster's acceleration, but agree with other Roadster owners that reduced weight would make a great difference in the driving experience. Acceleration of course, but agility perhaps even more. That is where the Elise shines and the Roadster could improve. Very currious as to whether the wheel bearing and perhaps some of the brake modifications might be applicable to the Elise.

I use my Roadster to commute around the city, after all, that is the way it's designed. And that is the typical daily range of the vehicle. So I can't see coughing up however much money to take my Roadster from 100% more miles than I need to 300% more miles than I need.

After all, it's not like I could take it on a long road trip and use a Super Charger. In fact Tesla's outright refusal to put in any HPC plugs seriously limits using the car for anything but a daily commute anyway. So what if I can get 400 miles? My destination city would have to offer some charging capability for me to make the return trip.

That's pretty much what a lot of us Roadster owners have asked for... an HPC identical to what we bought when we got the car, in one bay of the Super Chargers.

Note that the blog post ends with "We are confident that this will not be the last update the Roadster will receive in the many years to come."

There are so few Roadsters I wouldn't be surprised if these upgrades are done at nominal cost, or less.

I consider my roadster collectable. I do drive it extensively in the summer but think in time it will be potentially valuable as the door opening vehicle to the electrification of personal transportation. I have kept my holiday gift (radio remote roadster) and card from Elon Musk in storage and have considered getting the hard top just to complete the package. I wonder if upgrading would affect future collect-ability. Mine is a roadster sport in between 2.0 and 2.5 with the interior of the 2.0 but the motor and suspension drive train etc of the 2.5. The front end is also 2.0 style. Any thoughts?

Predictions are hard, especially about the future.

its like deja vu all over again!

The Roadster was not designed for long trips so it's not comfortable. I can't imagine a cross country trip after I drove one for 3 days in town.
1/2 battery pack for 200 mile range would cut weight 400 lbs for a lighter more agile car. With less weight it may even go further than 1/2 the total range because of a lighter load. I think Tesla should offer an option just like this which also has a lower cost.
