Chase Elliot drives the No. 9 Chevrolet Camaro ZL1 1LE for Hendrick Motorsports. Antonio Garcia and Jordan Taylor drive Chevrolet Corvette C8.Rs in the IMSA WeatherTech SportsCar Championship. Their wins this weekend at Charlotte Motor Speedway were, at least in part, to the 3D printing technology that General Motors has been innovating over the last few years.

This season, the Corvette C8.R, IndyCar, NASCAR Camaro and Silverado race teams have accumulated more than 80,000 miles of competition in vehicles built with 3D-printed parts.

"Chevrolet has a long history of technology transfer between our motorsports and production teams, and this is a perfect example of our approach," said Jim Campbell, GM U.S. vice president of Performance and Motorsports. "GM's 3D-printing capability speeds up our learning cycles and, in turn, these racetrack experiences help our additive manufacturing team move one step closer to using 3D-printed parts in production vehicles."

Earlier this year, two Corvette race cars, both C8.Rs, debuted at the Rolex 24 at Daytona, each equipped with 75 3D-printed parts. Among those parts are an oil tank, tank inlet and cap, air conditioning driver cooling box and integrated hydration system, power steering pump bracket and headlight assemblies. Since then, the C8.Rs have accumulated nearly 8,000 miles of competition in seven races.

The Chevrolet IndyCar V6 exhaust system is 3D printed, which has allowed the company to eliminate failure points and increase design freedom while reducing costs. Chevrolet IndyCar engines have run over 60,000 miles since the season kicked off at Genesys 300 at Texas Motor Speedway in June.

The Silverado off-road race truck debuted at the Best in the Desert Method Race Wheels Laughlin Desert Classic in October 2019. The Silverado competes in the 1200 Stock class, which limits changes to suspension, underbody and installation of race-safety equipment. The truck's rear damper shield is made of carbon-fiber reinforced plastic protects the rear dampers. It's made in-house by General Motors. Since its debut, the Silverado race truck has accumulated 900 miles of competition in six races.

Chevrolet engineers have optimized the aerodynamic performance of their NASCAR model using full-scale wind-tunnel testing. Oover 500 3D-printed prototype parts were used in testing to develop the ZL1 1LE body, which is new for this year. The Camaro ZL1 1LE is equipped with a 3D-printed gear cooling duct, which has accumulated nearly 18,500 miles of competition in 27 races.

"By utilizing 3D-printed parts, Chevrolet Motorsports is demonstrating the many benefits of additive manufacturing, including manufacturing efficiencies, mass reduction, parts consolidation, creativity and cost savings," said Audley Brown, GM director, Materials Engineering, Additive Design and Manufacturing. "3D-printed parts can offer equal strength and durability to cast or milled components, which is critical for product development and design."

Nuts & Bolts

 
 

Sony's team is testing the Vision-S on the streets of Austria.

One year ago Sony surprised the crowds at CES with the Vision -S, a concept vehicle meant to further the discussion on safety, security, and entertainment. The vehicle has moved from concept to prototype, taking to the roads of Europe for testing.

The car has been driving the roads of Austria since December 2020, according to the company, for technical evaluation. Evaluation of what? We're so glad you asked.

If the car is technologically similar to what has presented at CES last year, on-board is Sony's imaging and sensing technologies as well as software regulated using Sony's AI, telecommunication, and cloud technologies.

The car, which was built in cooperations with Magna Steyr, features 33 sensors, including CMOS image sensors and time of flight (ToF) sensors within the vehicle. These sensors are designed to detect and recognize people and objects inside and outside the vehicle, and provide "highly advanced driving support."

Each of the two rows of seating in the vehicle features Sony's 360 Reality Audio system. Bose has similar technology built into the Nissan Kicks.

The crossover-lie car's front seats have a panoramic screen in front of them that has the ability to display rich content.

Does this mean that Sony will begin to make cars? The quick answer is no. Sony does not appear itching to get into the car business though the products that result from this testing will likely be available to automakers offering additional competition for components in a fast-paced marketplace where the technology is evolving quickly.

The real winner here could be consumers who will benefit from the stiff completion between suppliers and be on the receiving end of better technology because of it.

The 2023 Cadillac Lyriq debuted in prototype form mid-2020. When it comes to market, Cadillac expects the Lyriq SUV to offer drivers 300+ miles of all-electric range, luxurious accommodations, and the buyers choice of rear-wheel drive or performance all-wheel drive. The Lyriq will come with Super Cruise, the General Motors hands-free driving system that allows for 200,000 miles of hands-free highway driving and automated lane change.

Cadillac Celestiq

In addition to showing the Celestiq here, Cadillac decided to show off its flagship electric car with some close ups. They don't give too much detail about the car, but we do know some interesting tidbits. Cadillac says that the car embodies their commitment to "reimagine what's possible in design and technology". The GM division will offer the Celestiq with a curated selection of hand-crafted materials and they've has hinted that there will be some customization options available for owners.

Chevrolet pickup

We don't yet know if it will be called the Silverado, but a Chevrolet pickup truck that runs on all-electric power is on the way. It's been confirmed that the plan is for the truck to have a maximum 400-mile range (likely when it's not towing or hauling much weight). Originally slated for a 2025 debut date, indications are that GM is pushing to get the truck to market sooner.

Buick EVs

In 2020, GM described the two new Buick models that are coming by 2023. They're both electric vehicles. The first, an SUV will be a model that offers "more conventional crossover proportion that maximizes interior space and cargo." The second is a Buick CUV that has "expressive proportions with a greater emphasis on form and athletic fashion." It looks like the SUV is on the right in the photo while the CUV is on the left.

"Mystery EV"

What is this mystery EV? We know the Cadillac XT4 is getting an electrified brother so there's a chance that this could that. Brightening and zooming in on the picture appears to reveal an SUV-like body design. We'll just have to stay tuned.

... and now let's turn the lights on.
