2017 Chevy Silverado HD Pulls Flag, Sets Guinness World Record


If you wanted to see the world’s largest U.S. flag being pulled by a moving vehicle, the place to be on Wednesday was the Texas Motor Speedway. That’s where Chevrolet captured some amazing shots of its 2017 Silverado 2500HD doing just that around the track.

The stunt was partly to kick off the 2016 State Fair of Texas this week and partly to show off the Silverado’s new, more powerful Duramax 6.6-liter V-8 turbo-diesel engine.

Wednesday’s feat actually set a Guinness World Records title for the World’s Largest Flag Pulled by a Moving Vehicle.  The United States flag flown by the Silverado HD for the record-setting drive measured nearly 40 by 80 feet, with an area of 3,186 square feet. To set the record, the truck had to travel 100 meters (328 feet) without the flag touching the ground. The Silverado more than exceeded that requirement, completing four laps around the Texas Motor Speedway’s 1.5-mile oval.


Chevrolet actually created two flags for the event: the U.S. flag used for the world record and a State of Texas flag to commemorate the start of the 2016 State Fair of Texas. Both of which will be on display at the State Fair through Oct. 23.

Unique 40-foot riggings on the trucks were designed to fold rearward, enabling the Silverado HDs to quickly enter and exit the track. That design requirement made it impossible to enable a driving roll-out of the massive flags. Instead, a team of 20 people launched and retrieved the flags, ensuring they did not touch the ground.

New Duramax 6.6L V-8 turbo-diesel

Back to that next-generation diesel engine, it’s been redesigned with a new, stronger cylinder block and rotating assembly. It also has a new GM-developed control system.

Chevy says it delivers quicker acceleration, more confidence in trailering up steep grades, better engine braking on descent and more refined noise levels cruising on the highway.The Duramax’s signature low-rpm torque production hasn’t changed. It offers 90 percent of peak torque at a low 1,550 rpm and sustaining it through 2,850 rpm.

Along with a new camshaft profile and improved cylinder head design, a new electronically controlled, variable-vane turbocharger allows the engine to produce more power with lower exhaust emissions. Its advanced variable-vane mechanism allows greater exhaust temperature capability. This enables the engine to achieve higher power at lower cylinder pressure.

Additionally, a new, patent-pending vehicle air intake system with functional hood scoop drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult conditions, such as trailering on steep grades. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.

Chevy says 89 percent of all HD customers purchasing trucks rated less than 25,000 pounds of towing capacity. Chevy says the new Duramax diesel in the 2017 Chevrolet Silverado HD offers them:

  • Unladen, 0-60 mph acceleration in as quick as 7.1 seconds, seven-tenths of a second quicker than the previous model (2500HD crew cab 4WD models)
  • Towing 10,000 pounds, acceleration from 50 to 70 mph in 10.6 seconds, 1.5 seconds quicker than the previous model (2500HD regular cab 4WD models)
  • When towing 23,000 pounds, in 110-degree Fahrenheit ambient temperature, the Silverado climbs the Davis Dam grade 40 seconds quicker than the previous model (3500HD crew cab 2WD with DRW).

The all-new Duramax 6.6L will arrive in the 2017 Silverado HD in early 2017.
