Chevrolet beats Ford in heavy-duty pickup "Rumble in the Rockies"

Checkout the results of the Chevy vs. Ford "Rumble in the Rockies" shootout by Pickuptrucks.com

Which automaker has the most "heavy-duty" pickup?
Pickuptrucks.com decided to torture test Chevy and Ford to see which would come out ahead in towing impossibly heavy loads up impossibly difficult hills. They called it the "Rumble in the Rockies."

The result was no surprise to us at Jim Butler Chevrolet: Chevy won.

Chevy challenged Ford to a Rocky Mountain tow test. Ford said no. Chevy moved forward and invited PickupTrucks.com and Diesel Power magazine to oversee the test with trucks bought off the lot from Ford and Chevy dealers.

Pickuptrucks.com compared a 2011 Chevy Silverado 3500 LT (397 horsepower, 765 pounds-feet of torque, 6.6-liter Duramax V-8) and a 2011 Ford F-350 XLT (400 hp, 800 pounds-feet, 6.7-liter Power Stroke V-8) and tested them pulling an 18,920 pound trailer up and down a 7.6 mile stretch of I-70 from Dillon, Colo., to the Eisenhower Tunnels, the highest vehicular tunnels in the U.S. at 11,000 feet elevation.
Pickuptrucks.com editor Mike Levine says the trucks were probably the most evenly matched heavy duties that they had tested. Besides the same rear axle ratios, the $54,805 8,440-pound Ford was just $65 and 220 pounds more than the $54,740 8,220-pound Silverado.

Gross combined weight rating for the Chevy was 27,140 pounds before four adult males jumped in and added another 800 pounds, for a grand total of 27,940 pounds, or 96% of the Silverado's maximum gross combined weight rating. The total for the Ford F-350 was 28,160 pounds, or 94% of the Super Duty's maximum GCWR.

The trucks were tested for towing time up the hill and exhaust brake effectiveness going down.
The fastest time up the grade for the Ford was 10 minutes, 46.8 seconds at an average speed of 42.41 mph.

The Chevy Silverado was significantly faster:
It finished more than two minutes ahead of the F-350, in 8 minutes, 38.2 seconds. Average speed cruising up to 11,000 feet was 53.63 mph, 11.22 mph faster on average than the Ford.

Going downhill with exhaust brakes on in both trucks, we had to apply the wheel brakes 10 to 11 times in the Ford to keep its speed below 60 mph. We had to hit the wheel brakes 1 to 2 times in the Chevy to keep its speed under 60 mph.

New Chevy Cruze Eco achieves 42mpg! That's Class Leading!!

NEW CHEVROLET CRUZE ECO ACHIEVES SEGMENT-LEADING 42 MPG ON THE HIGHWAY

Hybrid-Like Fuel Economy Starts at $18,895; Goes on Sale in January 

DETROIT – The official fuel economy numbers for the 2011 Chevrolet Cruze Eco are in and they’re good. Segment-leading good. It delivers an EPA-estimated 42 mpg on the highway (manual transmission models), with equally impressive city fuel economy of 28 mpg.

Cruze Eco’s highway fuel economy beats non-hybrid segment competitors – including 23 percent greater highway fuel economy than the Honda Civic – as well as the Ford Fiesta subcompact and many hybrid models. In fact, it’s better than Ford Fusion Hybrid, Nissan Altima Hybrid and Toyota Camry Hybrid.

“Chevrolet Cruze continues to redefine the compact segment, offering class-leading standard safety features, upscale amenities – as well as hybrid-like fuel economy without the price,” said Chuck Russell, vehicle line director. “The Cruze Eco is in a league of its own and will challenge perceptions of the efficiency available in a more affordable non-hybrid.”

The Cruze Eco carries an MSRP of $18,895 (including destination charge). It goes on sale in January.

To achieve its segment-leading fuel economy, Cruze’s engineers focused on aerodynamic performance, mass optimization and powertrain enhancements. The refinements in each area paid big dividends towards the car’s overall efficiency, while providing engineers with valuable information to help enhance the efficiency of future Chevrolet models.

“We left no stone unturned or piece of sheet metal un-weighed,” said Russell. “Our engineers were comprehensive and thorough when it came to evaluating and modifying the aspects of the car’s performance that contribute to fuel economy.”

Aero enhancements
Aerodynamic improvements over non-Eco manual-transmission models contributed approximately 6 mpg to the Cruze’s EPA-estimated 42 mpg highway fuel economy. Many were developed and refined in more than 500 hours of wind-tunnel testing of the Chevy Volt, which shares a core architecture with the Cruze. Examples include the upper grille, which has more “closeouts” to improve aerodynamics, a lower front air dam extension, a rear spoiler, a lowered ride height and underbody panels that smooth airflow beneath the car.

The Eco model also features an all-new technology in the compact segment: a lower front grille air shutter that closes at higher speeds to reduce aerodynamic drag and opens at lower speeds to optimize engine-cooling airflow. Another contributor to reduced drag is the use of ultra-low rolling resistance 17-inch Goodyear tires (used with lightweight wheels), which are also used on the Volt.

As a result of the aero enhancements, aerodynamic drag was reduced by 10 percent over a non-Eco model, with a coefficient of drag of 0.298. That places Cruze at the top of the class for mainstream compact cars.

Mass optimization
More than 42 changes were made on the Eco to reduce weight. It weighs in at 3,009 pounds (1,365 kg), compared to the 3,223 pounds (1,462 kg) of the Cruze 1LT. The diet program for the Cruze challenged engineers to look at all aspects of the vehicle’s construction, including hundreds of weld flanges on the vehicle. They were reduced 1 mm to 2 mm in length, which saved several pounds, while the sheet metal gauge thickness was reduced by about 0.1 mm in select components. This saved weight while preserving structural integrity.

Lighter wheels and tires are used on the Eco. They’re stylish, polished 17-inch alloy units with Goodyear tires that weigh only 36.5 pounds (16.6 kg) apiece. That’s 5.3 pounds (2.4 kg) less than the 16-inch wheel/tires of the Cruze 1LT for a complete savings to the vehicle of 21.2 pounds (9.6 kg).

Efficient powertrain
Cruze Eco is powered by power-dense Ecotec 1.4L turbocharged engine and a standard six-speed manual transmission. The transmission’s gearing is optimized for the model’s specific 17-inch wheel/tire combination and includes aggressive ratios for first and second gear coupled with a highly efficient, “taller” sixth-gear ratio for highway driving. That means engine rpm is reduced on the highway, which in turn reduces fuel consumption. A six-speed automatic transmission is available, with EPA-estimated fuel economy ratings of 26 city and 37 highway.

The Ecotec 1.4L turbo’s power ratings are 138 horsepower (103 kW) and 148 lb.-ft. of torque (200 Nm) between 1,850 rpm and 4,900 rpm. The wide rpm range for the maximum torque – a specific trait of turbocharged engines – helps the engine deliver a better driving experience and performance. The turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility.

The engine also features premium design elements that give it world-class smoothness and durability while also contributing to the Cruze Eco’s lower curb weight. They include a cast iron block with a hollow frame structure, hollow-cast camshafts and a plastic intake manifold.

Comparing the competitors
As a result of aerodynamic improvements, mass reduction and powertrain optimizaton, the Cruze Eco offers the best fuel economy in the compact segment, while delivering hybrid-like fuel economy without the hybrid price. The following charts show how it compares with primary competitors and popular hybrids.
