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."

2023 Chevrolet Corvette Z06 gets reveal date

Chevy draws a line from the Z06 directly to its racing program.

The new Chevrolet Corvettewas a revelation when it was finally announced. The car brought a mid-engine design to the Corvette line for the first time, and put decades of speculation over the shift to bed. We've all known that Chevrolet would eventually release an even higher performance Z06 version of the car, but now we know the date. The automaker just announced that the car will be revealed on October 26.

To build hype for the car's announcement, Chevy released a short teaser video of the Z06 tearing around the Nurburgring. It's clear from the film that the car we'll see in October will be a different beast from its standard predecessor, which mainly comes down to a big change in its powertrain.

The new Z06 is expected to feature a flat-plane crank V8 that will allow it to rev to 8500 or 9000 RPM. The car should see in excess of 600 horsepower from its howling V8, which will be sent to the rear wheels through an eight-speed dual-clutch transmission.



As it has done with other Z06 models, Chevy will bolster the Corvette's suspension and brakes to accommodate higher speeds and the jump in power. The car will be able to carry more speed into corners and stop in a shorter distance than its standard counterpart, which will improve its lap times at the track. Various active and fixed aerodynamics components are also expected.

The C8 Corvette's interior is anything but boring, and the Z06 will carry on with that tradition. We'll still see the long center strip of buttons and controls, along with a digital gauge cluster and nicely upholstered sport seats. The Z06 will most likely get more in the way of carbon fiber and race-inspired trim pieces, but the layout won't deviate from the standard car to a great degree.

VW's IQ.DRIVE system is also widely standard in the automaker's catalog. The technology includes a hands-on semi-automated driving function with lane centering and capacitive feedback on the steering wheel. Volkswagen says that in town, the system can help alert drivers to upcoming obstacles or to sudden changes in traffic activity ahead. IQ.DRIVE uses front and rear radar, a front camera, and several ultrasound sensors.

Several advanced driver assist features are also included in the IQ.DRIVE system. They include forward collision warnings, automatic emergency braking with pedestrian monitoring, active blind spot monitoring, rear cross-traffic alerts, adaptive cruise control with stop and go, lane keep assist, and a semi-automated vehicle assistance system.
