Record-setting stunt intended to celebrate truck’s new Duramax diesel V8.

Yeah, sure, your heavy-duty truck can tow boats and cars and all sorts of trailers. But if you want to really show off your patriotism, you tow a giant flag. That’s what Chevy did to tout the new Duramax 6.6-liter turbodiesel V8 in the 2017 Silverado HD – setting a new Guinness World Record in the process.

At Texas Motor Speedway, the 2017 Chevy Silverado HD hauled a giant, 40-by-80-foot American flag around the race track to celebrate both the truck’s new engine and the State Fair of Texas. Fittingly, Chevy also had a similarly massive State of Texas Flag on hand.

It turns out that hauling an enormous flag by track isn’t exactly child’s play. The flags were too big to deploy automatically, despite special 40-foot mountings on the rear of the truck, so 20 people helped launch and retrieve the flags while making sure they wouldn’t touch to ground. To set the new record, the Silverado HD had to tow the flags at least 100 meters without them touching the ground. In reality, the truck completed four whole laps of the 1.5-mile Speedway. Take that, world record.

The new 6.6-liter Duramax packs 445 horsepower and 910 pound-feet of torque, huge increases compared to the outgoing model’s rating of 395 hp and 795 lb-ft. The engine is also available in the 2017 GMC Sierra HD. Chevy says that with the improved power, a Silverado 2500 HD can accelerate to 60 miles per hour in as little as 7.1 seconds – 0.7 second quicker than the 2016 model. In other words, plenty quick to haul a flag around a race track.
