Goodyear ReCharge tire concept regenerates its own tread

The world of tires is evolving. Whether it's making them from recycled rubber or having a removable tread patter than can be switched out, which are two concepts Michelin is championing, there are coming major changes to one of the least-considered but most-important parts of a vehicle.

The Goodyear ReCharge tire concept is a creative take on the possible future of tires and it works similar to your Kitchen Aid mixer. The you want to make fresh pasta noodles, you feed a clump of dough through the mixer's attachment and out the other side comes noodles.

The tire's test takes a compound of renewable materials and feeds it through a series of pipes that feeds it out to the surface where it cures, forming functional new tread. The list of renewable materials includes dandelion rubber and synthetic spider silk. Goodyear says that these materials are strong enough for daily use rather than just a patch job.

The compound would be stored in pressurized canisters within each tire. Goodyear envisions that customers would be able to switch out canisters to meet the tread needs of the vehicle, theoretically allowing the tire to adapt for winter and summer driving conditions.

The concept tire requires no pressurization, meaning that it would never go flat. This feature is a developing trend with tire makers. Michelin debuted a tire last May that is able to be retreaded and also doesn't have to be pressurized.

While the tire is just a concept, Chris Helsel, Senior Vice President and Chief Technology Officer, Goodyear, explained to Engadget that the processes and features shown in the concept may find their way into future Goodyear tires within the next decade.

The IIHS may increase the speeds it uses to test advanced driver aids.

Insurance Institute for Highway Safety

The Insurance Institute for Highway Safety (IIHS) recently announced that it is considering changing the speeds it uses to test vehicle-to-vehicle front crash prevention systems. The agency currently tests the systems at 12 and 25 mph, but says that the speeds don't accurately represent the types of crashes the safety tech is meant to prevent.

Automatic emergency braking (AEB) is designed to notify of a possible collision and help respond with automatic application of braking. Just like a human using the brake pedal, it can stop the car, but higher speeds make it difficult to stop in time. The new tests would be conducted at 35 to 45 mph, which is the range where a large number of rear-end crashes occur. As Automotive News noted, an IIHS study showed 43 percent of rear-end crashes occur at speeds of 45 mph or less, so it's important to have a test that shows how well the tech performs at those levels.

A whopping 85 percent of 2022 vehicles earned a "Superior" rating in the current testing regime, so the IIHS will remove it from 2023 testing and Top Safety Pick award evaluations. Their view is that, since the majority of vehicles meet the criteria, it's no longer an accurate way of evaluating performance. In its place, the agency introduced a night test for automatic emergency braking systems that will begin next year.

The new Type R set a Suzuka Circuit lap record.

Honda

The new Honda Civic somehow improves on the formula laid out by its numerous predecessors and does so with style, refinement, and value. The Civic Si built on that foundation with a potent turbocharged engine and solid handling, but Honda's not done with the Civic. The automaker just teased the new Civic Type R, and it set records at Japan's Suzuka Circuit during a recent testing session.

The Type R lapped Suzuka Circuit in 2 minutes, 23.120 seconds, a record-breaking lap for a front-wheel drive car. The video features neat telemetry information on-screen during the lap as well, but the real excitement comes later when full specs are revealed.

Honda's been understandably mum on details on the new Type R's powertrain and performance numbers, but the car is expected to carry the same powertrain with its predecessor. The 300-horsepower turbocharged 2.0-liter four-cylinder engine made that car a force to be reckoned with, so the 2023 Civic Type R will likely continue carrying that torch.

Honda Civic Type RHonda will fully reveal the car this summer. Honda

Honda will reveal the car in all its glory this summer. As for pricing, the previous car started around $38,000, so the new model should be around there to start. That, of course, is before dealers mark it up and other lucky buyers snap them up for insane resale on an auction site.
