Am I the only one who's worried that Tesla is really starting to bite off more than they can chew? Right now their finances are a mess, they are publicly struggling to produce their most important car ever, their CEO is spending time figuring out how to dig holes underneath LA...and now they're announcing a semi truck and a roaster in the same day? Don't get me wrong, Teslas are incredible cars. But this seems like a…

They have planned this for years. The "new roadster" and even plaid has been announced for years. More than that, Production starts 3 YEARS from now. If they still have model 3 problems by then, I'll be surprised.

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.

Very unlikely. With power you weight beyond useful (this has basically been "solved" since the day someone built a cat around a ww2 military aircraft piston engine), acceleration is determined by aerodynamics (drag and downpressure), tires and the time spent shifting gears. It's pretty evident where Tesla has the advantage.

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 po…

I dont think it will before Tesla. The Porsche Mission E which is sceduled for 2019, is slower than a Tesla Model S P100D.

Those acceleration figures are meaningless. The Chiron isn't the best car on a circuit for example. I would be interested to see this car compete against say a gt3 on a track like Nürburgring :)

Drag racing is meaningless? I totally get that you might not personally like it, but meaningless?

Rolling acceleration and track handling are more important than Drag racing. Bit fed up of 0-60 times being such an important feature. 50-70 more important, handling a bit more important again. And of course for most people build quality, running costs and environmental credentials.

You may very well be right. The Mission E is closer to a Panamera than a 911.

Regardless, very interesting to watch the competition heat up.

Does this mean that Tesla is pivoting from their attempt to produce a medium-priced car in quantity and going back to hand-building high-end cars? Tesla is good at high-end, low volume products. But the Model 3 production fiasco shows they don't know how to do what Detroit and Wolfsburg and Toyota City do. This is in a way a step backwards. Tesla is going back to targeting the 1%. There are lots of little supercar co…

> But the Model 3 production fiasco shows they don't know how to do what Detroit and Wolfsburg and Toyota City do.

What fiasco? It was obvious from the start that their schedule was wildly optimistic. But that's probably just Elons way of pushing workers as hard as possible.

It's way too early to call the Model 3 a success or failure. Of course it takes a few months to ramp up and stabilize production. It's their first truly mass produced car, and there's a lot of differences from their previous model. Not to mention that they're using a brand new battery.

Let's wait a year to call the Model 3.

Circuit performance is meaningless. I'd like to see the gt3 accelerate to 100km/h under 2" for example :)

I mean what's interesting is handling, behavior in curves, power consistency, steering accuracy. Weight could be a drawback. Acceleration isn't the only metrics. Those are some reasons Porsche is considered to be making good cars.

0-60 in 1.9s for $200k that is affordable by a good range of people. I can see disasters happening with this car as young dudes lose control when they accelerate. There has to be some serious A.I to prevent this.

You don't use AI for that, you use a bunch of sensors and adaptive power or braking vectoring. Calling some heuristics "AI" is a massive stretch.

It could use some image recognition perhaps. "Detected male driver 18-25".

Shifting gears? Why does it have an advantage?
