Chevrolet Chaparral 2X Vision Gran Turismo could only work in a video game [w/video]

There's something wondrous about the Vision Gran Turismo series of concepts that has let companies go wild with completely imaginary concepts for Gran Turismo. For Chevrolet's crack at the idea, it has taken a page out of its performance past with the Chaparral Can-Am racers of the '60s and '70s, with its designers having reinterpreted that period look for the future of motorsports as the Chaparral 2X. In real life, the 2X looks even better than in earlier photos. The design takes inspiration from someone in a flying suit with head down and arms outstretched, an influence you can really see that in the vehicle's shape. The driver lies facedown inside with the instruments projected onto a visor. Unfortunately, the powertrain here is a complete flight of fancy and works purely in the video game world. It imagines a laser propelled by lithium-ion batteries and an air-powered generation to make 900 horsepower. The 2X has a theoretical top speed of 240 miles per hour and hits 60 mph in a lightning-quick 1.5 seconds. Scroll down to see the concept on video with Chevrolet designers describing their inspiration and read the company's full announcement. It's also downloadable in Gran Turismo 6. Chevrolet to Show Chaparral Vision Gran Turismo Concept Boundary-pushing, Chevy-powered race cars changed motorsports design DETROIT – When racers Jim Hall and Hap Sharp founded Chaparral Cars in 1962, few could have guessed how they would shake up the conformities of the racing world – and fundamentally change it. Through pioneering applications of aerodynamics and aerospace technology, and a partnership with Chevrolet Research and Development, Chaparral Cars advanced the science of racing cars. It also triumphed on the track over well-established sports car companies from around the world, using Chevrolet horsepower. It was that spirit of innovation that inspired the Chevrolet Chaparral 2X VGT concept race car developed for the Vision Gran Turismo project, which celebrates the 15th anniversary of PlayStation® racing game Gran Turismo by inviting manufacturers to give fans a glimpse into the future of automotive design. It will debut at the Los Angeles Auto Show, Nov. 19, and gamers will be able race the Chaparral 2X VGT following the release of an online update for Gran Turismo 6 during the holiday season.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

Three automotive tech trends to watch in 2018 and beyond

Every year, technology plays a bigger and bigger role in the auto industry. To put things in perspective, 10 years ago iPod integration and Bluetooth were cutting-edge in-car innovations, and smartphones and apps weren't yet a thing since the first iPhone was only about six months old. And I can't recall anyone talking about autonomous cars. Compare that to today, with mainstream coverage of the auto industry dominated by autonomous technology, along with electrification and almost every move made by Tesla. These three topics were the most significant trends of car tech in 2017 and I believe they will continue to shape the auto industry in 2018 and beyond. Let's examine them. Full Autonomy Gets Closer to Reality While there were many developments this year that indicate we're inching closer to fully autonomous vehicles, I was behind the wheel for hours to witness one of them. In October I had the chance to test Cadillac Super Cruise on a 700-mile, 11-hour drive from Dallas to Santa Fe – and had my hands on the wheel for maybe 45 minutes max throughout the entire trip. Super Cruise is far from making the Cadillac CT6 or any GM vehicle fully autonomous, and has limitations such as functioning only on pre-mapped main highways. While it simply adds a layer of lane centering to adaptive cruise control, the technology will go a long way in making mainstream drivers more comfortable with letting machines take over. On a separate front, GM is pushing ahead with fully autonomous vehicles and announced last month that it plans to launch of fleets of self-driving robo-taxis in several urban areas in 2019. While most automakers are also in the race to make autonomous cars a reality, GM's turbocharging of its efforts appeared to be in response to Waymo, which announced just weeks earlier that its Early Rider Program in the Phoenix area would go completely driverless. The Early Rider Program launched last April, offering the public a chance to ride in Waymo's autonomous Chrysler Pacifica minivans. In this new phase of testing, Waymo is using its own employees as guinea pigs instead of the public while the vehicles operate without a human behind the wheel, and takes another giant step forward for fully autonomous driving.
