620 mile range seems like a lot of battery weight for a performance car. Is that weight of batteries necessary to supply enough current and to reduce heat load on individual cells? Or would there be a smaller battery pack that would be even more performant due to reduced weight?

Yes, a larger battery pack can provide more power. You can see this at work in Tesla’s lineup already: the longer range variants also have better acceleration.

If that top speed ("Over 250 mph") is accurate wouldn't it put it in contention for "Production car speed record" per: https://en.wikipedia.org/wiki/Production_car_speed_record Additionally I hope nobody ever tries to "red line" it on a public road for their own and everyone else's safety. 4.2 sec 0-100 and a 250+ mph max is a very temping but potentially deadly combination. Does anyone who owns a Tesla know if you c…

Usually there are different driving modes. IIRC, in the Tesla sedans, "Chill" mode ups the 0-60 acceleration time to around 8 seconds.

The convertible roof STORES IN THE TRUNK? That is just an absurdly non-luxurious design decision.

Sports cars tend to be neither luxurious, comfortable nor practical. One of the many reasons that I never understood why one would buy something like a new Lamborghini Huracan, when you for a similar price could be looking at a Rolls Royce Phantom.

Sports cars are a specialized good, by nature. You're explicitly deciding to sacrifice some things in favor of some other thing (in this case performance). The people you are going to sell it to are therefore exactly the people that are willing to make that sacrifice, the people that just wanna go really friggin fast

There are a few ways in my Model 3:

- Valet mode - Set a max speed with a pin - Comfort vs. Sport which changes the driving dynamics drastically

It's probably not the first 6 figure supercar with dangerous specs.

Many of the cars on that list are 7 figure (or are in 2019 dollars). So we're likely going to see more of these types of cars on the road just given to its relatively lower price.

So they unveiled it 2017, and now they are selling it? So now you can reserve. Hmm, maybe I missed it but when do you then actually get one? Is it the same thing like their other cars (i.e. when it is done)?

I am a bit confused about what is novel about this. It is not the unveiling, so it must be the reservation possibility but I might be wrong.

I just watched the video from the 2017 unveil and it says it will be available in 2020.

This range is not really surprising. Musk has previously stated that the performance limitation on the Model S has always been the battery. So the bigger the battery, the more juice you can pull for crazy launches. The 620 mile range is just a side-effect of putting in a bigger battery so it can hit the acceleration and top-speed numbers needed to put it in the super-car big-leagues.

The Challenger Hellcat is ~$60k and similarly dangerous (~800hp, 0-60 mph in 3.4 seconds. Top speed - 203 mph. )...so I agree.

At what performance point does a vehicle require specially designed tires? I assume you can't just put a set of Michelin Pilot Super Sports on this.
