PickupTrucks.com puts the trucks through their paces by taking them up a 16% uphill climb.
Hi, this is Mike Levine from Pickuptrucks.com. And we're here at general motors proving grounds in Milford, Michigan for the 2010 heavy-duty shootout. Today, we're taking nine trucks. We've got three one ton pickups and six three quarter ton trucks.
The one ton trucks are hooked up to 12,000 pound trailers. And the three quarter ton trucks, they've got 10,000 pound trailers. We're going to run them up a 16 per cent grade. Let's go ahead and see how they do. This is where we separated the men from the boys. Hills this steep expose even the slightest powertrain and platform weaknesses. And with only 800 feet of runway, there was no time to recover and mask any shortcomings in any of the trucks. The three quarter ton gas heavy duties were the first trucks up the monster hill. If any tests confirmed the advantage of pairing a powerful engine with a six speed transmission, it was this one. Because a 6.2 liter Ford V8 and the F two 50 ran up the hill a full five seconds faster than its next closest competitor, the Chevy Silverado 2,500. It finished in 30 point 75 seconds at 29 point 53 miles an hour. All of the gas trucks remained in first gear during their fastest runs with some hitting almost 5,000 RPM as they strained up the climb. Following the gas trucks up a 16 per cent hill were the three-quarter ton diesels. The Ford F two 50 had lots of rear axle traction. The Ram 2,500 had a tough time gaining traction, but the Silverado seemed to get the best start, thanks to its new tracks control system that seems very well integrated with the Duramax and the Silverado's new rear suspension. The Silverado 2,500 diesel finished the climb in 25.6 seconds at 32 miles an hour. It beat the F two 50 to the top by just over a second while the Ram took the third spot five seconds back. Finally, the one ton Dooleys took their turn climbing the 16 per cent incline. The Ford F three 50 had difficult balancing, sending its power to the back wheels while keeping its traction control system in check which kept cutting fuel to the engine when it sensed wheel slip. The GM and Ram trucks didn't have this issue because they lack traction control. Even though the Ram 3,500 mega cab wasn't fast, it had the smoothest starts. But it was the GMC Sierra Denali 3,500 that crossed the line first. It finished in 28.6 seconds at 27.6 miles an hour. The Ford came in right behind it, just over a second back and one mile an hour slower. For fun at the end of testing all the trucks and two wheel drive, we repeated this last test in four wheel drive. And this time with extra traction, the Ford actually beat the GMC up the hill. What an amazing performance from all the trucks at GM's proving grounds on these steep grades. So there you have it. For the full results of the heavy duty shootout, check out Pickuptrucks.com.
