Toyota teases groundbreaking ‘holy grail’ EV feature expected to debut in 2027-28, and it’s a world first

Toyota, out of all automakers, is apparently very close to achieving what many EV makers can only dream of: a solid-state battery car.

If everything goes well, the new EV will be launched in 2027 or 2028.

We’re not talking about a concept here, but a full-blown production car.

And here’s why that’s so important.

Here’s how solid-state batteries work, and why they’re important

Solid-state batteries could change the game because they’re more energy-dense.

All things being equal, a solid-state battery gives you 25 percent more driving range compared to a corresponding liquid-state battery.

That’s because solid electrolytes – hence the name solid-state battery – are better conductors for battery components that work in tandem to generate energy.

With the same weight and size, you get more energy from a battery that’s solid and easier to cool.

It’s a win-win situation.

Toyota and Mercedes want to pioneer this technology

Toyota isn’t exactly the most EV-obsessed automaker in the world – the fact that its latest supercar is a gas car proves it – but the Japanese automaker is serious about solid-state batteries.

If they keep their promise, Toyota’s upcoming electric vehicle will be the world’s first production solid-state car.

But that’s assuming Mercedes doesn’t beat them to the punch.

Mercedes has been working on this type of tech for a while.

Just a couple of years ago, they managed to run a Mercedes EQS for 1,000km (620 miles) on a charge.

About a year later, they did even better: 750 miles on a charge.
