• Silverado, Sierra V6 return 18 mpg city/24 mpg hwy
  • 4-wheel-drive models return 16 mpg city/22 mpg hwy
  • Towing capacity is up to 7,200 pounds

The new 2014 Chevrolet Silverado and GMC Sierra will achieve up to 24 miles per gallon in highway driving. General Motors recently announced the impressive fuel economy is possible thanks to the automaker's new 4.3-liter V6.

According to General Motors, Silverado and Sierra pickups equipped with the V6 can also return 18 mpg in the city. Both the 18 mpg city and 24 mpg hwy figures apply to 2-wheel-drive models. Meanwhile, 4-wheel-drive Silverado and Sierra pickups should return 16 mpg city/22 mpg hwy.

With their newly announced gas mileage numbers, the Silverado and Sierra offer massive fuel economy jumps over last year's model. The Environmental Protection Agency (EPA) rated the 2013 Silverado and Sierra at just 15 mpg city/20 mpg hwy with their standard V6. That engine, also 4.3 liters in size, is completely different from the 4.3-liter V6 in the new models.

The new fuel economy figures also place the Silverado and Sierra near the top of the full-size truck pack for gas mileage. Today's segment leader, the RAM HFE (for High Fuel Efficiency), returns 18 mpg city/25 mpg hwy. It's only offered with 2-wheel drive. The Ford F-150's standard 3.7-liter V6 returns 17 mpg city/23 mpg hwy in 2-wheel-drive form, placing it below the Silverado and Sierra.

In addition to high fuel efficiency, the new 4.3-liter V6 also boasts strong payload and towing ratings. GM says trucks equipped with this engine can haul more than 2,100 pounds, while they can tow up to 7,200 pounds. Those figures outshine the RAM 1500, which can only haul about 1,500 pounds and tow around 6,500.

General Motors has not yet announced fuel economy, payload or towing details for larger Sierra and Silverado engines. In addition to the new 4.3-liter V6, the trucks will also offer new 5.3-liter and 6.2-liter V8s when they begin reaching showrooms this summer. Pricing for the Silverado starts at $24,585 with shipping, while the Sierra is slightly more expensive.

What it means to you: The Chevrolet Silverado and GMC Sierra combine impressive fuel economy with strong towing and hauling abilities.
