Goodyear creates tire containing 90% sustainable materials

Goodyear has created a prototype tire containing 90% sustainable materials that the company also believes could improve fuel economy and EV range. Called a "demonstration tire" by the company, the tire isn't ready for production, but has passed all applicable regulatory testing, as well as Goodyear's internal testing, according to a press release. That testing also showed lower rolling resistance than a comparable conventional tire, which helps boost efficiency and thus decrease the amount of fuel or electricity needed to go a certain distance. The demonstration tire uses 17 ingredients that are sustainable, or at least have a lower environmental impact than conventional tire materials, across 12 tire components.

That includes four different types of carbon black, a common ingredient in tires that's used to reinforce the rubber compound. Carbon black is usually made by burning petroleum products, but Goodyear used methane, carbon dioxide, plant-based oil, and end-of-life tire pyrolysis oil as feedstocks, which the company claims reduces carbon emissions. Another green ingredient is soybean oil, which is used to keep the rubber compound pliable in different temperatures. It replaces petroleum-based products, and is sourced from leftover soy from food and animal feed, according to Goodyear. The company is already using soybean oil in some production tires, including racing tires. Also included are silica made from rice husk waste residue, polyester from recycled bottles, pine-tree resin, and polymers from bio feedstock. The steel for this radial tire's cords is made from a high level of recycled content, produced in an electric arc furnace that allows for both more recycled content and less energy use, Goodyear claims.

This tire isn't going into production, but Goodyear does plan to start producing a tire with 70% sustainable materials this year. This comes just a year after Goodyear showed a concept tire with 70% sustainable content. Goodyear isn't the only company trying to make tires more sustainable. Bridgestone has been developing natural-rubber tires with desert shrubs from the American Southwest, while Michelin and Hyundai have partnered to make tires more environmentally friendly. Goodyear also has some more far-out tire concepts. the company said last year that it's developing airless tires, and in 2020 it showed a regenerating tire concept aimed at reducing waste. Goodyear hasn't discussed a firm timeline for commercializing those designs, but for now increased sustainable content is an important goal.

Starting January 30, v13.40 of Fortnite on iOS and Google Play will become unavailable to players under 18, Epic Games has announced. Although Fortnite was removed from the iOS, macOS and Google Play stores in August 2020, the game is still playable by users who already had it installed, but it’s been stuck on the v13.40 update and been somewhat buggy.

Lamborghini Aventador successor likely revealed in patent drawings

Last update 18 January 2023, It appears the Lamborghini electrified V-12 supercar set to replace the Aventador has been revealed early. Motor1 has discovered patent drawings filed by Lamborghini last November with the World Intellectual Property Organization, for a supercar that's likely to be the Aventador successor due out later this year. Information included with the patent lists Mitja Borkert, Lamborghini's current design chief, as the designer of the car in the drawings. Many of the details also match elements seen on prototypes for the Aventador successor, such as the heavy cut lines of the hood, the position of the headlights, the lines of the side blades, and the Y-shaped taillights. The design appears to be influenced by the Terzo Millennio, a 2017 concept that shares many of the elements shown here.

The Dodge Storm Z-250 was the brainchild of advertising executive Fred Zeder

Last Update 17 January 2023 1953 Dodge Storm Z-250 The Dodge Storm Z-250 was the brainchild of advertising executive Fred Zeder, whose father (also named Fred) was a key figure in the early days of Chrysler and had worked on the Airflow models. The younger Zeder specified a Hemi V-8 and a tube-frame chassis with interchangeable bodies—one for on-road touring and one for racing. The Bertone-designed body shown here was designed to be removed by unscrewing just four bolts and replaced with a lighter fiberglass body for racing. It's unknown if the fiberglass body was actually built, Kendall noted. The car was originally white with a black roof, with different hub caps than the ones currently fitted. The Storm appeared at the 1953 Turin auto show, but it may have made other undocumented show appearances as well. It made quite a splash when Zeder parked it outside his Manhattan office, attracting so much attention that police got involved, Kendall said.
