The Tesla roadster specs are insane! No exotic carmaker will be able to match it (taking price as a consideration). (no Ferrari, or Lambo, can get that close. This is Formula 1 acceleration speeds). Plus 620 miles of range, and it is a 4 seater. Expensive as hell, but this is exotic car territory.

Near 10x the price... I think OP unconsciously factor in the price.

Yes. The Chiron matches it in speed, but not acceleration. 1.9s vs 2.4s to 60mph. Since the roadster has a 250+ mph figure, the tires are probably going to be one of the limiting factors. (same with the Chiron). " The Chiron can accelerate from 0–97 km/h (60 mph) in 2.4 seconds according to the manufacturer,[4] 0–200 km/h (120 mph) in 6.5 seconds and 0–300 km/h (190 mph) in 13.6 seconds. In a world-record-setting tes…

Chiron is traction limited for most of its run; I presume to beat the Chiron's time the Tesla Roadster has better tyres for initial grip.

0-60 in 1.9 seconds is ABSURD

To be precise, 1.44 g. For comparison, a Falcon 9 v1.1 rocket -- without payload -- at takeoff mass has 1.19 g of thrust.

I used to navigate/copilot a 480ci methanol powered jet sprint boat, Group-A class. It would pull just over a G accelerating, and did the 0-100kph sprint in 1.9 seconds. That boat could also do 100kph-to stop-to 180 degree turn - to 100kph the opposite direction in about three seconds. (This is something unique to jetsprint boats, they can pirouette like nothing I've ever experienced). That pulled insane G's, so much so that you needed the HANS device around your neck to stop the weight of your helmet breaking your neck.

Imagine having to strap into a HANS device to drive a road car. I want this future.

I wonder at what speed you get that range. Those specs are in Bugatti Veyron league, even beating it at acceleration (for 1/8 the price tag), but at full speed, the Veyron empties its full tank in... 12 minutes. I'll let you calculate how many miles that is at 250mph.

1 fifth of those 250 miles: 50 miles

Not to mention that once the benchmark is set, everyone competes to break it. See: Hennessy Supercars

Any car that has less than 100 of produced units, it just exotic car prototypes territory. If you can't really go an buy one, does it matter? It is not a real 'production' car.

"Venom GT "World's Fastest Edition" (2014)[edit] Is a limited (3 units) version of the Venom GT coupe commemorating the Venom GT coupe's 0–300 km/h Guinness World Record.

The vehicle went on sale for US$1.25 million.[14] All three units were sold to customers shortly after their production was announced by the manufacturer."

Toyota owns Lexus, Ford had Jaguar and Land Rover, Hyundai owns Genesis, Volkswagon has Bentley, Fiat owns Ferrari. Just like other car manufacturers, Tesla does it all. edit: Ford didn't start Jaguar.

Tesla doesn't run a volume production line. All the major players have production lines that make about one car a minute. Tesla isn't able to play in the big leagues until they can do that.

Fair enough, but how will they ever achieve that without first trying to compete in this outrageously competitive industry?

I would really love to know how they are getting such a large battery capacity in a vehicle of this size. Is this a generational leap in energy density? What kind of materials are being used here?

My brother pointed out that other Tesla cars (even the semi they announced) have a "front trunk". This one's hood is seamless. Our theory is that under the entire front hood is batteries.

Makes sense to help weigh down the front too (so as not to go airborne while doing 0-60 in 1.9s).

0-60 mph in 1.9 sec This might sound really stupid. But isn't performing such acceleration on a daily basis close to the limit of harming one's health? I mean micro concussions for example. Really curious because that acceleration is amazing!

>But isn't performing such acceleration on a daily basis close to the limit of harming one's health?

Yes, and also the health of nearby drivers, bystanders and inanimate objects.

Most likely a lot more weight.
