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.

Six-week production shutdown planned for 2016 Chevy Volt

It's no surprise that GM is winding down production of the first-gen Chevy Volt as it prepares to start building the second-gen for a launch in the second half of this year, but for now, things are proceeding as planned, according to Chevrolet spokesperson Michelle Malcho. Malcho told AutoblogGreen that GM "is still making first generation Volt" and that there has been no announcement about when that will change. The only details she would divulge is that, "It will be this summer." "Halting Chevrolet Volt production in anticipation of the all-new 2016 model year is a smart move for GM," Akshay Anand, an analyst at Kelley Blue Book's KBB.com, said in a statement. "[The move] allows for less inventory and incentives on the outgoing model. Hybrid and alternative fuel vehicle sales have been declining for some time now, with gas prices well below the summer prices of 2014." Volt production will cease in the weeks before the traditional two-week auto plant shutdown over the July 4 holiday. A high inventory of Volts is a factor in the production cuts, but not the only one, Malcho said. The plant construction, engineering changes and pre-production plans for the new Volt and CT6 all were part of the decision, she said. Nationwide, there is about a 200-day supply of Volts on dealer lots (roughly 100 days in California, the car's biggest market), according to the Detroit Free Press, which says there will be a six-week retooling period (twice as long as normal, but other sources say the shutdown will be four weeks long) at GM's Hamtramck plant this summer to get ready for the second-gen model. The 2016 Volt will get an increase in all-electric range to 50 miles and will then get 41 miles per gallon when the battery runs out. It also has a fifth seat that straddles the battery tunnel and a larger li-ion battery. Related Video: The AP contributed to this report.

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.
