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.

Best new convertibles for 2024 and 2025

If you’re here, then youÂ’re already in the right mindset. Convertibles rule, and we have all the best convertibles listed for you further below. Driving around with the top off is an experience you need to live to fall in love with. When the weatherÂ’s right, youÂ’re on a proper bit of road, and the car youÂ’re in is a good one, few automotive experiences can top it. The experience is extra special when you have a musical exhaust note filtering directly into your ears and echoing off the landscape around you. And while rolling the windows down and opening a moonroof can get you part of the way there, it's nothing like feeling the wind wash over you with absolutely no roof overhead. The downsides can be just as harsh as the upsides when youÂ’re in the wrong conditions, though. Convertibles are typically worse to live with in cold climates, and driving around with the top up frequently means you might be subject to more road noise and worse visibility than an equivalent coupe. And when it comes to pure performance, convertibles are inherently compromised from a weight and structural rigidity perspective. All that said, we still think the upsides outweigh the compromises if your number one objective is to simply have fun. ItÂ’s a good thing then that there are a ton of great convertibles for sale these days. And no, the list of possibilities isnÂ’t as long as it used to be. Long-running standbys like the Mercedes-Benz E-Class and C-Class Convertibles are gone (replaced by the one CLE-Class). And so are others like the Audi TT Roadster, Fiat 124 Spider and Nissan Z Roadster. Nevertheless, opportunities abound from the ultra-cheap and fun, to physics-defying supercars and everything else in between. WeÂ’ll give you options for which new convertibles we think are the best below, so read on to find out.   Mazda MX-5 Miata Pros: Lightweight and compact; great engine and transmission combo; one of the most raw and pure driving experiences out thereCons: Not great for tall people; infotainment is dated; tiny trunk Read our Mazda MX-5 Miata Review Miata is always the answer, right? In this case, that rings even more true than usual. In fact, you could stop reading this list right here and go buy a Miata and youÂ’d likely be just as happy driving it around as you would be in any of the more expensive offerings that follow. ThatÂ’s just the magic of the MX-5.

2015 Callaway Corvette Z06 gets new supercharger, adds $17K to starting price

Callaway's proud tradition of modifying Chevrolets is about to add a very significant chapter this weekend, as the company prepares to unveil a modified version of the 2015 Corvette Z06. The engine mods are simple, though we expect them to be very potent. That's because Chevy has replaced the factory supercharger with a new "GenThree" unit that's nearly a third larger than what's bolted on in Bowling Green. A new intercooler is also added, along with a new high-flow intake system. Beyond that, the changes are exclusively of the subtle cosmetic variety. There's new badging inside and out, as well as new engine covers, floormats and an underhood plaque. Naturally, there's documentation to verify the Callaway Z06's authenticity, and the comfort that comes with a three-year, 36,000-mile warranty. Callaway has priced the upgrade package at $16,995, in addition to the price of the stock Z06. While we're still waiting to hear official power figures, that seems like a reasonable asking price for what were wagering will be a major increase in power. The Callaway Z06 will debut this weekend at the National Corvette Museum's C7 Bash in Bowling Green, KY. Expect more details following the debut. Scroll down for the official press release.

Here's a sneak peek at the new package. Based on Chevrolet's track-proven Z06, Callaway engineers' no-compromise approach takes this Corvette to an astounding power level. While advertised Callaway horsepower and torque are pending final validation, the Callaway package adds Callaway's new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design and unique triple-element intercooling system. Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature. By exposing the supercharger's large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling. The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction.
