That's huge news! I wonder if it will have the mods for sustained high speed running?
It will also have a better frame or suspension for higher performance. I will remember to ask for more details tomorrow when I go back.
I will try to ask tomorrow.
If anyone wants specific questions asked, post them here. I will try to get some details.
James, for starters you could try for:
- Mass of the battery
- Capacity of the battery / range
- Likely cost of the car
- Whether it will be stripped out - i.e. no radio or air con
- Whether it is 300BHP as WarpedOne has mentioned above
- Drivetrain 2.0 type features (e.g. for sustained autobahn running / track use)

Wow, this is huge news! I wonder how much of this is specific to the Roadster, or bleed-over from the newer tech planned for the Model S?
It should be a relatively straightforward thing to reduce weight enough to get the acceleration up (with sacrificing range, comfort, etc). But a much more difficult thing if they plan to increase the sustainability of the top end.

Maybe they don't intend to change the weight significantly as this might trigger re-doing crash tests. It could just be tweaks to the PEM/battery to realise more (all?) of the 300 hp the eMotor can deliver, but the EPA range figures would still stand.
Sustaining high speeds really needs better motor/PEM cooling but once you increase weight to achieve that, battery capacity becomes the weakest link in the chain. Maybe it's not worth it outside of a Model S prototype.
Great to see them continuing to push the Roadster specs. Is this Powertrain 1.6? :biggrin:
James: Can you ask if there are plans to tweak the regen profiles given that a more powerful motor can also be a more powerful generator (but I suspect that safe braking under regen is the limiting factor here) and when will the instrument panel get a re-design? Thanks.

Elon and other Tesla members have mentioned "considering" doing such a thing. Nothing has been announced that they are actually planning to do so.
I guess by sport model, they don't quite yet mean a track car. What I would like is the battery to be mounted in a way to provide for easier swapping. As it is, you have to take the whole rear suspension apart.

Yes - hence the full day to convert the glider into a real car. It seems like future models should streamline that design if they can...
I went back for my second test drive today. A beautiful Electric Blue Roadster with only 2,000 miles on it. This is a newer marketing car that is there for customers and potential customers. This time I was more relaxed and had time to enjoy myself on wide open roads with little traffic. But the few cars that saw me were really looking at the Tesla. It definitely draws a different reaction from other drivers. I was getting excited waves from other drivers who clearly recognized what a Tesla represents. One guy in a Charger was really funny, he held up his hand to his ear as if he was listening for the noise. He clearly loved seeing the Roadster running at speed on the highway.
About the "sport" model, I gave them the questions posed in this thread. They were all good questions. But I cannot say anything because there is an upcoming press release about this topic.
Tesla has been great to me with the two test drives and I need to respect their desire to do the press release. It is coming very soon.
My salesperson said that all of the questions posed in this thread will be answered and there will be even more info included in the press release. In fact, I think some of the questions in this thread will be added to the press release. Perhaps your questions prompted them to include the info because other customers will likely have the same questions.

That's fair enough. I thought someone from Tesla HQ might see this thread and ask the staff to sit on the information.

I respect that. I always honor requests to keep something too myself or to sit on some info for a couple days/weeks.
From a PR perspective, though, a little bit of advanced info among fans helps build anticipation and can increase the impact of the press release/announcement. It also helps fans feel connected to the brand. Just as long as a few beans are left in the bag.

Actually, I was told by a technician it only takes about 2 hours to install the drivetrain. (Of course there are other details before a car goes to the customer.) But still, for a track situation you wouldn't want to be taking apart the suspension. Don't know that there's a way to get around it for the current chassis, though.

I wonder if the Sport model Roadster will be called the "Roadster S" to stay with the current themes? :smile:
