Corvette C8 vs. Tesla Roadster?!

I drive a Tesla Model 3 Performance daily and absolutely love it. I have a charger in my garage where I just plug it in each night. Haven't been to a gas station in a couple months (the length I've had the car). 310 mile range and my daily commute is about 80 miles so I've never come close to needing to go to a supercharger. The car is unbelievable and hitting 0-60 in 3.1 seconds consistently and effortlessly makes the daily commute a bit more manageable. The tech is second to none and the OTA updates keep adding cool functionality to the car. Honestly, I never thought I would like them as much as I do, but I, like most other reviewers out there, fell in love the second I hit the accelerator.

Given my experience assembling computers, developing software, and many years in the information technology field (development and security) I'm hardly a cave man stuck in the past. I'm just saying that with my years in the technology field I have noticed that often times when new tech is predicted as the only way thing will be done in the future it does not always happen. It could be the new technology never developes to fully meet the needs that the old technology did, or the cost are two high and never come down even when it seems it should, or that a third option will form that did not previously exist.
As such I try not to make too many predictions other than the prediction that often new technology doesn't always work out how we think it might. Just this millennials 2 cents.

C'mon man, that's a little harsh. People may disagree on Tesla, but we all agree on Corvette!

I bleieve the tesla supercar will be amazing yet until it releases none of us will know what the benefits and weaknesses will be.
to try and compare it to a c8 corvette high performance model that slao is not out yet is kind of futile.
if I took a guess ? Id imagine the tesla supercar will be a performance superstar based off how great the model 3 performance model is.
id imagine battery thermal management will be a challenge that will be resolved as last I read the tesla model S ludicrious mode had an issue on a road course with I believe car and driver magazine but I could be mistaken with regards as to which magazine tried and had an overheating issue on the track after one lap.
lets hope that challenge will be easily resolved for the quarter of a million dollar tesla supercar.
ive driven the tesla model S ludicrious mode and its an amazing performance sedan for the street and the drag strip.
no reason to believe tesla wont resolve thermal management
EV s are taking over from a performance standpoint.

So you get the car, you do the fast 0-60 a dozen times.
You show all the buddies that will ride with you.
You make the video with the squealing blonde in the low cut blouse.
OK now what? You're bored that's what.
A car has to offer a lot more so when I hear all about how the acceleration is so quick and that is the focus why the car is so good. It's bye bye baby bye bye.

Here are some things I don't see EV's overcoming in the near future if ever:
1) Charging speed compared to a gasoline car filling up. To fill up a 150 kWhr battery in five minutes would take 1.8 megawatts. I don't see that happening. Do you know how big the charging cable would have to be? Using the typical 13% charging loss, the car would have to dissipate 234 kW. That's the equivalent of 156 space heaters.
2) High performance driving not reducing the range to unacceptable levels due to too much energy not being recovered during heavy braking.
3) Range being increased without increasing the weight of the car excessively.

Regardless of how we feel as individuals, Electric is the future. In the same way buggy markers are farriers said the horseless carriage was a fad, I see history repeating itself w/ the gasoline combustion engine aficionados. With ranges increasing and prices dropping more and more people will transition to electric. IMO, It won't happen overnight but as charging stations start to pop up in more places it will happen eventually.
The "Achilles Heel" to electric is our power grid. If it goes down we would be screwed as a electric transportation nation. One reason I have not picked up an electric as a second car. Florida Hurricanes and 10 day power outages. In a perfect world, every house would be solar powered (so a power grid would be unnecessary), but that ain't gonna happen w/ corporations invested in power distribution and oil.

- Tesla Supercharger v1 maxed at 60kW, v2 at 120kw, v3 at 250kw, Porsche's network at 350kW, and a new network in Germany at 450kW. Charging speeds vary greatly on the battery's current SOC, temperature, etc., but the point is that the charging technology is advancing rapidly. Additionally, for your average driver (myself included), we simply plug in when we get home. I'll likely never visit a supercharger unless I'm on a road trip. If it takes 10 minutes to charge the car to 80%, it's a small trade-off for not having spent one second at a gas station for the last 'X' months/years.
- This is a tough one, since you generally aren't concerned with range when you're doing true "high performance driving". I got less than 5 mpg in my Viper when on a racetrack. That would equate to roughly 80 miles range. We had to fill up at the nearby station constantly, along with just about every other thirsty car. Same would apply to EV.
- With the latest move from 18650 to 2170 battery packs, energy density was increased substantially. Ultra-capacitors and dry cell technology are currently being tested to make another leap forward in density. I recently read something interesting about the battery weight a while back. The logic was basically, vehicles that require great range aren't as concerned with weight as say sports cars, any more than their ICE counterparts. A 200+ kw battery pack will be in the Tesla and Rivian truck, along with the major player truck/SUV lineup. I'm honestly not even sure I'd want the 200kW pack that's in the Tesla Roadster for a 600 mile range. It's a supercar, I'd rather have half the range and save the weight. 300 miles is plenty on a car like that (better than any Ferrari, Lamborghini, etc.). Point being, we're not far off now.

Solar power indeed, all free, sure it is.
We enough natural gas in this country to make electricity for 1,000 years. WTF do we need to put these hideous, high priced, junk panels every where. Ridiculous.

Seeing you are in Prosper, I assume you have been to the bumpy hell that is Eagles Canyon (although I hear the new owners are completely redoing the track, not just the surface but also the design, fingers crossed) but in my E46 M3 I used to get less than 4MPG there! I think it was usually 3.2-3.6. And that was before they had gas local to the track, that sucked.
