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.

Weekly Recap: Racing legend Jim Hall explains Chevy's futuristic Chaparral concept

"I said our cars are built to be winners." – Jim Hall Racing legend Jim Hall never thought he'd be a video game consultant, but when Chevrolet asked for his advice to create a futuristic Chaparral for the Vision Gran Turismo series, he was eager to help. He reviewed early sketches and suggested some changes that made it onto the concept, including the addition of a camera that's mounted onto a mast over the cabin to aid the driver. The Chevy Chaparral 2X Vision Gran Turismo concept was revealed this week at the Los Angeles Auto Show and will be part of a downloadable update for PlayStation 3's Gran Turismo 6 in December. Theoretically, at least, it uses a laser-beam propulsion system and an air-powered generator to produce 900 horsepower in the video game. It's capable of sprinting to 60 miles per hour in 1.5 seconds en route to a top speed of 240 mph. Those gaudy performance specs – even in the virtual world – came at Hall's urging. "I said our cars are built to be winners," Hall told Autoblog on the floor of the Los Angeles show. The 79-year-old drove Lotus racecars in Formula One before launching the successful Chaparral Cars in the 1960s. Like his innovative Can-Am racers, the Vision Gran Turismo project has an eye toward the future. It also introduces the iconic Chaparral name to a new generation of fans, and hopefully, Hall says, gets them excited about engineering and design. "It emulates what we did in the '60s," he said. And what they did back then still resonates. Chaparral Racing and Chevy partnered more than 45 years ago for development work on the composite monocoque chassis, lightweight alloy powertrains, automatic gearboxes and active aerodynamics. "He [Hall] walked right back into this and was able to apply thinkings and learnings," said Clay Dean, General Motors executive director of advanced design. The Chevy Chaparral 2X Vision Gran Turismo concept was created at GM's North Hollywood advanced design studio, and it will be on display at the show through November.

Chevy, Lincoln dealers say they still want sedans

Detroit automakers have famously turned their backs on sedans as they make the strategic bet to double down on money-making trucks and SUVs, but dealers for at least two American brands are giving the companies contrary signals. In separate recent interviews with leading national dealer councils for Chevrolet and Lincoln, Automotive News reports that both brands’ dealers still see a need for cars. The publication published a Q&A interview with Mike Bowsher, chairman of the Chevrolet National Dealer Council, who said Chevy dealers managed to hold onto market share last year despite the phase-out of the Cruze compact sedan and hatchback, thanks to products like the Spark and Sonic subcompacts and the Trax and Equinox crossovers. But, he acknowledged, “We do feel like we could use a car, especially in the low-MSRP range.” The comments follow similar recent comments from Tom Lynch, who chairs the Lincoln National Dealer Council. He told AN, “If weÂ’re not in segments where there is still a good amount of business, I think the company and the dealers lose out.” The Cruze was one of the victims of GMÂ’s November 2018 announcement of plant closures, with production having ceased with the closure of GMÂ’s Lordstown, Ohio assembly plant last year. GM sold 47,975 Cruzes in 2019 but a healthy 142,617 in 2018. At Lincoln, Lynch said the council has been telling the company it needs to stick with the sedan segment, despite plans to kill the MKZ sedan in the coming months and unconfirmed reports that the Continental isnÂ’t long for this world, either, despite the buzz of the suicide-door Coach Door Edition, shown in the photo above. Lincoln sold 17,725 MKZs and 6,586 Continental sedans in 2019, down a combined 15%, but still good for almost 22% of overall Lincoln sales. It's worth noting that Lincoln competes in a luxury segment that still expresses allegiance to four- and two-door cars. Even Cadillac, its cross-town rival, is staying active with the upcoming CT5 and CT4 sedans. Lynch pointed to Tesla as evidence that strong sedan products can resonate with consumers, though he conceded that “What that looks like for Lincoln going forward, IÂ’m not sure of.” For now, anyway, Chevy still offers the Sonic and Spark subcompacts, the latter of which saw sales climb 32.5% in 2019 to 31,281 (Sonic sales fell nearly as steeply).
