Bridgestone reinvents the wheel

THE WHEEL is being reinvented with the development of an airless tyre for cars that could put an end to punctures and be kinder to the environment. Currently being developed by Bridgestone, the Air-Free Concept Tyre has an exterior tread that looks normal but inside there are plastic spokes that support the outer casing. This does away with the need to pump up the tyres, which means a puncture is no longer a problem as the tyre cannot deflate.

2012 Chevrolet Corvette upgrades focus on track performance

To keep up on the track with the Vipers and Super Snakes of the world, Chevrolet has upgraded the Corvette for 2012. There's no change to the engines or their output for 2012, but you will shave a few seconds off your lap times with the newly optional Michelin Pilot Sport Cup Zero Pressure tire. Only offered on the Z06 and ZR1 models, the package includes the tires, 285/30-19 in front and 335/25-20 rear, and lightweight aluminum Cup-style wheels in satin black or machined finishes.

We sample Honda's car technology of the future

Ahead of the Tokyo Motor Show 2013 we’ve been to Honda’s research and development facility in Tochigi to see and experience some of the Japanese firm’s new and upcoming products and technology. We’ve covered the new Honda Civic Type R in some detail separately, but among the other cars driven here is the next generation Honda Jazz (known as the Fit in Japan), no less than three different types of Honda hybrid system, including one similar to that fitted in the forthcoming NSX supercar, and an all-carbonfibre CR-Z prototype. On top of which, we’ve also experienced a self-driving car, watched a crazy automatic-parking demonstration and sampled the latest version of the all-electric Micro-Commuter, Honda’s equivalent of the Renault Twizy.
