Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

Indian tuner turns Chevy Optra into Mustang 'Eleanor' replica

If you are a big fan of automotive oddities, this may come as a little treat. If you are a Shelby or Mustang diehard, prepare to have your sensibilities violated.
The master fabricators at BigDaddyCustoms are the minds behind what you see above. At first, it appears to be a slightly misshapen custom Mustang, modeled after "Eleanor" from Gone In 60 Seconds, but upon further examination, something appears to be amiss. In fact, the custom shop, based in India, has created an Eleanor replica grafted upon a lowly Chevrolet Optra. While it may take a second for the Optra to ring a bell, you should recognize its badge-engineered sibling, the Daewoo Lacetti, used on Top Gear.
We don't know what star would opt for the Reasonably Priced Car in Shelby's clothing, but it's clearly someone more concerned with the aesthetic than the performance credentials of this automotive mash-up.
