Tesla Shocks Us With New 2020 Roadster, Does 0-60 In 1.9 Sec!

[supra93]

Tesla has used the unveiling of its long-awaited Semi to shock the world and unveil the second-generation Roadster, a car which will be the sportiest vehicle every created by the electric automaker.
Elon Musk has been promising a new Roadster for a number of years and has just announced that it has arrived. Like the original, it is a sleek two-door but unlike its predecessor, is totally bespoke and adopts a seriously sexy design.

Incredibly, the base second-generation Tesla Roadster will reportedly reach 60 mph (96 km/h) in just 1.9 seconds and reach 100 mph (160 km/h) in a mere 4.2 seconds. What’s more, it will run down the quarter mile in 8.9 seconds thanks to a 200-kWh battery pack and apparently hit over 250 mph.

According to Musk, the new Tesla Roadster has a 620-mile range and despite what the images may suggest, it does have four seats, however, the rear seats are exceptionally small.

From a design standpoint, the new Roadster is a dramatic departure from any other Tesla before it. The front end is characterized by a pair of slim LED headlights and typical Tesla curved body panels, while the rear looks more like a radical concept car than anything remotely close to a production model. Among the most intriguing design elements are wafer-thin taillights and an aggressive diffuser.

During his speech announcing the second-generation Tesla Roadster, Musk said he wants it to serve as the final nail in the coffin for ICE vehicles, hence why such lofty performance targets have been set. If they’re all achieved, it could very well represent the future of performance cars.

Unsurprisingly, the second-gen Tesla Roadster will be more expensive than its predecessor. In fact, the base price will start at $200,000 with a $50,000 reservation required. For true die-hard Tesla enthusiasts, a Roadster Founders Series will be available, starting at $250,000.

The numbers don't matter. Not much engineering effort is needed to create a crazy fast EV. One big battery, two big motors, done. If not double up.

What's interesting is the battery pack. 200 kWh in what is supposed to be a sports car. Even at (a highly unprobable) 200 Wh/kg it would mean OVER A TON of battery with their latest 2170 Li-ion cells. This thing will be a boat to drive. I wonder if the semi-truck/roadster 2 announcement today is related to any advances in battery chemistry, because if not Tesla is in some trouble. But given how Tesla likes to brag about things that are five years away, I highly suspect these will be based on old chemistry and no breakthrough has happened in Tesla's labs.

Now that is a problem. Fisker just announced a breakthrough in their SSB (solid state battery) development this week, while TMC is a year ahead with R&D already done and production engineering beginning this year. Tesla will die a horrible death if it could not have its proposed Li-S battery ready before Toyota could launch its disruptive SSBEV.

TMC has no plans for Li-S since it has determined it to be an unfeasible technology long time ago. Their roadmap involves SSB in 2021 and Li-Air in 2030. The latter, if successfully developed, will be the holy grail of EV technology (same level of energy/power density as gasoline) that will even make FCEVs irrelevant.

This Is How Fast The New Tesla Roadster Really Is

It's one thing to read about a new car's specs, and a completely different story to experience it firsthand.
all-new Tesla Roadster, most of us won't get near it until early next decade, so the only way to check it out right now is by watching these short video posted online.

One of the clips bears Electrek's name, and it shows Tesla Motors' sportiest vehicle ever doing a couple of short accelerations, shot via a 360-degree camera, so that you can adjust the angle.

To those that missed our initial coverage of the second generation Tesla Roadster, we will remind you that it packs a 200kWh battery pack. Zero to 60mph (96km/h) takes just 1.9sec, or approximately half a second faster than a Bugatti Chiron, and its digital speedometer will show 100mph (160km/h) after 4.2sec.

Moreover, the initial numbers also reveal that it can run down the quarter mile in 8.9sec, before topping out at over 250mph (402km/h).

This impressive performance comes at a steep price, as the new Tesla Roadster is said to start at $200,000.

Several analysts think this is a stunt to raise money to cover manufacturing costs for the Model 3. If you've been paying attention to Tesla and Musk, the next announcement was supposed to be the Model Y CUV, so its absence is interesting.

There's no chance in hell a semi program or a sports car program can be profitable given Model 3's abysmal situation. There's no doubt whatsoever this is purely a money raising stunt.

0-60 in 1.9 seconds? Damn. You'd probably have to be experienced either in NHRA-class stuff or as a fighter/stunt pilot to take that kind of G-force without some pretty adverse effects.

That's less than 1.5G. You endure much more for longer in a roller coaster.

That's assuming that the acceleration and G-force is linear. Electric motors, unlike gas engines, produce their maximum torque right off a dead stop, at start-up.

But 0-60 acceleration (for such a powerful car) is limited by tyre traction which means almost constant acceleration in that time window. Also, even with infinite grip tyres the electric motors will produce perfectly linear acceleration for the exact reason you've just mentioned.
