Too bad it can’t maintain that performance for any extended period of time. Battery is known to overheat if you drive it too hard.

I’m no Tesla defender, but how is anything “known” about a car that was first announced a couple of hours ago?

I think he's referring to the fact that Model S's are known to overheat and go into limp mode when pushed hard at the track.

Not necessarily applicable to this particular vehicle.

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.

Lighter tires as rolling at 400kph+ is not a requirement and a fraction of the interiors

I'm thinking what this means to gas car makers. Wave 1: "It's all about legacy and prestige, not speed/acceleration". Wave 2: "The track handling isn't all that good, how can drivers take that corner at full power without losing traction". Wave 3: "Alright, we will go electric too".

Porsche has already pulled out of WEC (Le Mans, Rolex 24 Hours) in favour of Formula E and is planning to release a electric vehicle by 2019. My bet is that they're going to get an electric performance vehicle on the road way before Tesla.

Moreover, what does this mean to Tesla? Competitors with decades of manufacturing experience cranking out reliable, fast electric vehicles with likely better build quality might pose an interesting problem.

Gas will always have sound. The growl of an Aston Martin V12 on startup, or a Lexus LFA screaming through a tunnel, or the flat-plane V8 burble from a Mustang GT350. EM cars only have a dull whine the faster they go. Motorheads are secretly all musicians who happen to love driving. The best combination is ultimately both though, hybrid systems are already used quite frequently in everything from LMP1 WEC racers to mo…

Put speakers in there. Many nonelectric sports cars already use them to "enhance" the sound.

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!

Yes, that's a real problem. I took my Model S P85D to the track (fun, but felt really heavy in corners) and had a concussion for 3 weeks afterwards. And that was just Insane mode, not even Ludicrous. The Roadster should come with a health advisory

F1 cars accelerate faster than the Roadster's advertised numbers and the drivers don't wander around constantly concussed.

I am curious how you managed to get a concussion in a heavy sedan that can only maintain 0.87g of lateral grip. Were you in a collision?

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. Base Specs Acceleration 0-60 mph1.9 sec Acceleration 0-100 mph4.2 sec Acceleration 1/4 mile8.8 sec Top SpeedOver 250 mph…

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.

Most of the car do since tank is sized to fuel consumption and full throttle petrol eat a lot of fuel - even a smart can reach 2km to the liter flat out and I know my alfa tank would only last 15 minutes give or take from the figures I got lapping at Monza

>If I was a consumer sitting on a Model 3 reservation I would be pissed that they are taking yet more money for yet another car they can't seem to ship at scale. I mean, by the same reasoning, Model S owners should be pissed, Model X owners should be pissed too. But the money from both seems to have made Model 3 possible.

True I haven't even touched on them either! Tesla has yet to prove they can build cars at scale, they are nothing compared to current auto manufacturers. I think they are biting off more than they can chew.

People are overreacting on Model 3 challenges. It is a really simple car to manufacture. Once the supply chain bottlenecks are ironed out, it will be really easy to pump out cars at scale. They already produce 2500 S and X per week.

Paper stats are one thing but show me this beating even something like a GT3 in an actual circuit race, or posting a Nurburgring time worthy of the price tag.

I’m sure in another 5 or 10 years they’ll get there but these figures are for headlines not the track.

The Porsche Mission-E will handle continuous top-speed just fine without overheating, so I figure Tesla will come up with a competitive cooling solution until 2020 as well.

Porsche has hundreds of millions of dollars of R&D poured into the 919 hybrid Le Mans Prototype, which I imagine will translate to the Mission E. Tesla has no such experience.

yet.
