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.

GM starting to talk seriously about 200-mile EV

We've been hearing word of a 200-mile EV from Chevrolet for a while now. First, there was General Motors then-CEO Dan Akerson hinting at a $30,000, 200-mile EV that would take the competition by surprise. Then Akerson confirmed that GM is working on a 200-mile EV in a speech in March. LG Chem, which supplies batteries to GM and other automakers, recently said it was working on batteries for EVs with a range of 200 miles. GM's head of global product development Mark Reuss just re-confirmed that there are plans for an EV with a 200-mile range, and sources have told Automotive News what that car will be. While Reuss didn't mention anything about a specific model or platform, two undisclosed sources with knowledge of GM's plans have said that an EV with a range of about 200 miles is indeed in the works, and that it will be based on the Chevrolet Sonic. The sources also gave a timeline for the car, saying it is slated for sometime in 2017. According to Reuss, the plan is for Chevy to offer a lineup of electric cars, with the 200-mile EV joining ranks of the Chevrolet Volt and the Spark EV. He didn't hint at a timeline, but if the sources are correct, we could see a Sonic EV being built within a few years. Reuss sees demand for it, too. When speaking of the Spark EV, currently only available in California and Oregon, he says that "people wish we would sell it all around the country." If he's right about that, it's not difficult to imagine people taking interest in Chevrolet's 200-mile electric car, whether or not it's a Sonic.

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.
