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.

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

The Hellcat is dangerous, but I wouldn't say it's as dangerous as a Model S or Model 3 Performance, all that power can't hook so the Traction control lights are just flashing from a stop.

Meanwhile a Model S P100D is a whole second faster to 60 with this incredible 20mph 'JUMP' with zero lag, I got a test ride in one and felt as if something like a slip on the throttle off the brake would find you 20 feet inside a storefront, which there's a few examples of online lol.

I'd argue the rear wheel drive makes it more dangerous. Lower velocity, but way more unpredictable.

“The first supercar to set every performance record and still fit seating for four.” Where are the remaining two seats?

Probably with the 3rd row of the Model Y.

What's the mile range at 250mph? Also, that picture look cartoon-ish... I wonder if it was modified in any way?

> Also, that picture look cartoon-ish... I wonder if it was modified in any way?

I think it's pretty much a given that a photo has been shopped unless they specifically say it hasn't. Even then one should be skeptical.

But I agree, the degree of post processing in the photo makes it look completely artificial.

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…

There are plenty of cars that are capable of taking out school busses full of nuns and orphans. The ‘16 Corvette driven by my 72 year old mother is a car I personally am incapable of fully thrashing on a public road without eventually slamming into something. And that only cost $50K.

The Roadster, should you be the kind of dumbass that can barely keep your ‘94 Camaro between the lines, will merely (please pardon the pun) accelerate the process.

Range is easy: just add more battery. It’s expensive, but this is an expensive car.

But space and weight are limited on a supercar. So you have to choose one.

Space is no problem. Make the floor a bit thicker, done. Look at how much space the battery takes up in other Teslas... if you can find it.

Added weight is not desirable but it’s not a dealbreaker.

I call bullshit on this. 1000km range and 400km/h top speed? Obviously you can't have both but each of this is unrealistic enough on its own. You can't even go 400km/h on the Autobahn, which roads are they building this for? And fully loaded SUVs like the Hyundai Kona get somewhat about 500km in normal crusing mode. 1000km is either a breakthrough in battery technology or measured/calculated when going 50km/h at best…

620 Miles range?! that's huge! for an all electric car, and beats even a lot of gas-powered cars

You only get 620 miles if you drive it like a Yugo. ;) Otherwise, if you do lots of hard starts and stops, you'll probably get about 400ish.

Is that really true? Electric cars should theoretically be able to handle rapid acceleration more efficiently than ICE vehicles, and regenerative breaking makes deceleration less wasteful as well. How much energy would really be wasted by pushing the vehicle to its limits?

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?

Theoretically, you could get more performance out of a smaller pack, the VW ID. R used just 43kWH to set the electric record at the Nürburgring Nordschleife. However, that's a lightweight race car. Tesla seemed to want to make this a really livable car with lots of superlative records so by using super light construction paired with a massive battery they can build a car with incredible range (This range would be a p…

There are tradeoffs around capacity, power, and longevity. I suspect Volkswagen doesn’t care if the battery in their prototype racer is trashed after a year, so they can push it hard.

Just look at all the videos of idiots spinning out and ramming spectators while leaving Cars and Coffee. You’d never be able to achieve that sort of loss of control in a Tesla.
