Idk what the 0-60 of my leaf is but I beat every one off the line when I want to. It makes me far more comfortable on the freeway to get all the power I want on demand to quickly and safely make a maneuver. I would never have considered it before owning an EV, but now that I have one, I'll definitely be considerate of it in my next EV purchase. Previously I had only had crappy used ICE vehicles, and the acceleration…

Depends on the year, it used to be around 11s, latest models brought it down to 8-7 seconds. Normal ICE cars are in the 12-18s range, sometimes 5s is ridiculously fast and that kind of acceleration should _never_ be used in the middle of traffic or city roads.

I drive a Jetta GLI, it’s 6.1 (edit - 6.4?) seconds - fairly fast but not a fancy sports car, no obnoxious reviving required. It’s a four cylinder, too!

I see way too many Toyota battery articles for a company that can barely put out an EV. They're all promises... in the future, they swear they'll beat everyone, but they just released a Lexus EV at $60k with 196mi range and 5sec 0-60.

They were supposed to have solid state battery cars and vehicles for the Tokyo Olympics. It was obvious that wasn't going to happen and it didn't.

Toyota has been completely asleep at the switch for EVs which is baffling since they pioneered the hybrid electric vehicle.

What's really strange is after having such a huge lead and hybrid electric vehicle, they have really crawled behind other manufacturers and producing plug-in hybrid electric vehicles which are really just a plug adder onto the vehicle.

It really is mystifying

Keep in mind they're basically isn't a single car manufacturer outside of China and maybe Tesla that are actually doing original battery research. They are all partnering with actual battery manufacturers like Panasonic, Samsung, etc

My Tesla’s 0-60 makes a huge difference in normal driving, because the acceleration profile at low speeds is a lot more “do the right thing now”. Driving my minivan or other ICE cars feels laggy to me now.

A lot of that is the automatic transmission in ICE drivetrains. a manual transmission delivers immediate acceleration but still not as good as a Tesla

Hydrogen has a higher energy density by volume compared to a li-ion battery. People really need to check their fact here.

Hydrogen is a gas, which expands or compresses to fill all available space, so its density varies. People really need to check their understanding of physics here.

I don't know what Toyota's future looks like in terms of electrics, but I know that I won't own an electric car until they sell an electric Corolla, or something equivalent.

I wouldn't hold my breath for something called a "Corolla". Their roadmap is a big gaping hole for the next 3 years.

However, this exists, and kind of looks like a tall Corolla:

> 5sec 0-60. When did this become a metric that mattered to any normal person? Do you even know the 0-60 of your car? Do you realize how quick 5 second is to 60mph? Most sports cars of a generation ago couldn't touch that. Why do you feel it needs to be faster? It's plain dangerous to inexperienced drivers.

There's a saying in car manufacturers that Americans buy horsepower but drive torque.

Torque is generally what you need when you need that. Beat the person off the line because you didn't merge into the right turn lane early enough acceleration onto the highway and two lane highway passing.

Horsepower is largely a metric for top speed of the vehicle, and if we're talking about in a relative statistic for road cars, top speed is far more useless than 0-60

I would assume, but perhaps be wrong, that it would be liquid Hydrogen pumped into a vehicle's tank, and much like a tank of propane, the liquid expands back into a gas as pressure decreases (due to consumption). Hydrogen vehicles have the advantage of being refillable in minutes, much like petrol based vehicles - yet the only byproduct is water vapor, making them completely environmentally friendly. Hydrogen is also…

Toyota does sell the Mirai[1] in California, it has pressurized tanks[2] I think keeping the hydrogen liquefied would take low temps as well, which would use a lot of energy for refrigeration (and or a lot of volume for insulation).

Aren’t Lexus cars luxury?

Lexus is the new Cadillacs they might have a 400 horsepower engine and really high performance but the people that drive them drive them like slugs.

They're the cars of old conservative rich people that don't buy American and primarily considered reliability
