Take eight friends along for the ride in Toyota’s 26-foot-long Tundrasine concept

Toyota has traveled to the SEMA show to unveil a brand new concept dubbed Tundrasine. As its name implies, the one-off is a Tundra pickup truck that has been painstakingly transformed into a luxurious limousine at the company’s San Antonio, Texas, assembly plant.

Pushing the term “full size” to the extreme, Toyota has added more than 90 inches of sheet metal to the Tundra Crew Cab’s wheelbase. As a result, the Tundrasine stretches over 26 feet from bumper to bumper, and it’s possible to park a long-wheelbase Mercedes-Benz S-Class between the concept’s axles. Clearly, Las Vegas was the ideal town in which to premiere the Tundrasine.

Inside, the outlandish Tundrasine stands out as the most luxurious truck Toyota has ever built. Accessed via one of eight doors, the cabin eschews the traditional sofa-like seat that’s usually found in limousines and instead adopts posh captain’s chairs for the second and third rows of seats, while the fourth row appears to retain the stock model’s bench seat. The nine occupants travel in a spacious, well-lit atmosphere whose design is inspired by the world of private jets. Highlights include brown leather upholstery with beige contrast stitching, airplane-style tablets built into the armrests, and a small forest’s worth of real wood trim on the door panels — all eight of them — and the dashboard.

Power for the nearly 8,000-pound truck is provided by a stock, 5.7-liter V8 engine that makes 381 horsepower and 401 pound-feet of torque. A six-speed automatic gearbox sends power to all four wheels, but what effect the extra sheet metal has on performance and gas mileage is anyone’s guess at this point. The donor Tundra returns 13 mpg in the city and 17 mpg on the highway.

It goes without saying that the Toyota Tundrasine is a one-off model designed for the SEMA show, not a preview of an upcoming addition to the car maker’s lineup. However, Toyota hasn’t revealed if it’s open to the idea of building a limited number of Tundra-based limousines for livery services.

The state of solid-state batteries: We may be on the cusp of an EV revolution
Factorial solid-state battery

Electric vehicles may have become a whole lot more popular over the past five years or so, but that’s despite some issues they still face regarding things like limited range and slow charging speeds. The result of these issues is that plenty of buyers are unsure about whether an EV might be for them. But there’s one technology that has been hailed as a savior for all of the EV issues related to batteries, and that’s solid-state battery tech.

This technology has been so hyped for so long that, at this point in time, it seems not only almost mythical, but as if we might never actually see it in the real world. So, what’s the state of solid-state batteries right now, and how far are we from finally seeing them and reaping their rewards? Here’s a look.
What are solid-state batteries?
What is a solid-state battery in the first place? Solid-state batteries keep the fundamentals of traditional battery design, offering an anode and a cathode with a porous separator in the middle, and a substance through which electrons flow from one side to the other. This, in turn, creates a circuit. But while a conventional battery is built with a liquid electrolyte solution on the inside, a solid-state battery instead makes the separator between the anode and the cathode the electrolyte itself.

Audi RS e-Tron GT Performance unveiled as a 912-hp electric sedan
2025 audi rs e tron gt performance specs pictures features

Audi's roster of past high-performance models includes the rally-winning Quattro and the V10-powered R8, but the new RS E-Tron GT Performance outguns them all. With up to 912 horsepower on tap, this electric sedan stands proud as the most powerful Audi ever built.

Starting with the RS E-Tron GT, which is related to the Porsche Taycan, engineers updated the front axle's electric motor and integrated a new, lighter electric motor into the rear axle to reach the 912-horsepower figure. Audi notes that this mammoth amount of power can only be unlocked temporarily when the launch control function is engaged, however. Other improvements helped the German company add horses to the E-Tron's cavalry, including a new chemistry for the 105-kilowatt-hour lithium-ion battery pack's cells and a revised cooling system.
