New Features Improve Efficiency

2019 Silverado 2500 New Features Improve Efficiency

The 2019 Chevy Silverado 2500 includes some exciting new features that allow this heavy-duty truck to use less fuel to get where it needs to go. These adjustments add up to money saved on fuel for drivers who are used to shelling out for the amount of gas needed to drive large work trucks. With the 2019 model, you get efficiency along with all the power and hauling ability expected from a pickup truck. Engineers have created a truck that has the look and feel you love from Chevy Silverado, with a few improvements. A lighter weight, redesigned engine, and new aerodynamic design make all the difference in terms of fuel efficiency and mpg.

Reduced Weight

Silverado 2500 Reduced Weight

A major advantage of this year’s Chevy Silverado is that it weighs in at 450 pounds less than the 2018 model. This makes a huge difference in terms of fuel efficiency since that’s almost half a ton less weight that the engine needs to propel forward. This weight difference was achieved by using mixed materials and incorporating aluminum into the truck’s design. The truck bed, cab, and frame are still made from steel, to ensure safety and durability even with the new lighter-weight design.

Improved Aerodynamics

The new design for this truck has managed to reduce drag by 7%. When it comes to aerodynamics, every percentage counts. Engineers used two subtle spoilers to increase airflow over the cab and truck bed. The combined effect keeps air from collecting in the open truck bed, where it would otherwise cause a lot of drag. Preventing this means that drivers no longer have to cover their truck beds to get an aerodynamic ride. The truck also has “air curtains” that direct airflow away from the front wheels to reduce drag. The side mirrors are larger than previous models, but redesigned so air glides smoothly over them instead.

Updated Engine Designs

2019 Chevy Silverado 2500 Updated Engine Designs

Two engine options are available for the Chevy Silverado 2500: the Duramax® 6.6L turbo-diesel V8 and the Vortec 6.0L V8. The Duramax option is specially designed to allow space for the catalytic converters to be located as close to the exhaust port as possible. Both of the engines feature the new Dynamic Fuel Management, which improves upon the cylinder-deactivation method that previous engines used. This system adjusts according to the engine load and can shut off up to seven cylinders in response, for a more efficient engine.

2019 Chevy Silverado 2500 Fuel Consumption vs. Fuel Economy

In discussions about fuel efficiency, sometimes consumption and economy are used interchangeably. It’s important to make sure to use the correct phrase. Fuel consumption measures how many gallons are required to drive a hundred miles. Lower fuel consumption is ideal. Fuel economy, however, measures the number of miles per gallon. This is where we use the abbreviation mpg. It’s also known as fuel efficiency, even though an actual measurement of fuel efficiency would be written as a percentage that shows how much gasoline was used to propel the car forward, and how much gasoline was wasted.

Fuel Mileage

2019 Chevy Silverado 2500 Fuel Mileage

The Environmental Protection Agency is generally a source for information about vehicles’ mpg, but it doesn’t release information about heavy-duty pickup trucks. According to reports, the 2019 Silverado 2500 diesel mpg is about 16 on the highway and 11 in the city. When compared to the other years’ releases, this is one of the most efficient models. It stacks up to the fuel efficiency of other trucks, which offer mileage that is either comparable or fewer miles per gallon. It is ranked by Motortrend as ‘Above Average’ in terms of value rating. The Ford F-250 and F-350 are ranked as Average and Below Average, respectively. Fuel cost is projected to make up 31.7% of the 5-year cost of ownership for the Chevy 2500.

Fuel Efficiency

The Chevy Silverado 2500 compares favorably to other heavy-duty trucks that use diesel engines. With an efficiency of up to 16 mpg, it fares well for such a large and powerful vehicle. The Duramax engine has 445 horsepower and 910 lb.-ft. of torque at 1600 rpm, making this powerful enough to use as a work truck. It can pull up to 15,400 pounds. Hauling large loads and trailers is no problem with a machine of this size. The Vortec engine has 360 horsepower and 380 lb.-ft. of torque at 4200 rpm. It equips your truck to haul up to 14,400 pounds. Both offer 6-speed transmissions equipped for use with a heavy-duty truck. Either of these engines will serve you well and provide a smooth, steady drive.

Factors in Fuel Efficiency

2019 Chevy Silverado 2500 Factors in Fuel Efficiency

Fuel efficiency is affected by several factors, so not every driver will get the exact same fuel efficiency, even for the same model of car. When you look at the reported Chevy Silverado 2500 diesel mpg from various individuals, their efficiency will be affected by how they use their trucks. How well your vehicle is maintained, driving habits, natural variations in fuel, vehicle modifications, and the age of your engine all affect how efficiently fuel is used. When extra exertion is put on the car, through heavy loads or lack of maintenance, more gas is used.

Variations In Fuel

Variations In Fuel that Affect MPG

Gasoline has some variations that affect mpg and fuel efficiency. The majority of gas sold in the US includes ethanol, usually with a content of up to 10%. Only light-duty vehicles can use gasoline with a higher ethanol content than 10%. If you use gasoline with a high ethanol content, it can decrease fuel economy by up to 4%. Oxygenated fuel and reformulated gasoline have the same effect, causing a decrease from 1% to 3%. As strange as it sounds, the energy content of gasoline can even fluctuate depending on the season, with summer providing 1.7% more energy than winter gasoline.

Maintenance Is Key for Efficient Fuel Usage

Maintenance Is Key for Efficient Fuel Usage

Engines don’t operate at their most efficient until they have driven a few thousand miles, so a brand new truck will not be at its most efficient until it’s broken in. On the other hand, an engine that badly needs a tune-up will burn more fuel than a well-tuned engine. Tire issues and brake problems can both add extra resistance to your ride, reducing efficiency. Regular tune-ups and maintenance prevent these unnecessary strains on your car and make it run more smoothly overall.

Effect of Carrying Loads on Fuel Use

Effect of Carrying Loads on Fuel Use

As you might expect, pulling a trailer or carrying heavy objects in your truck bed will reduce your mpg. Cargo racks and other add-ons also increase the amount of aerodynamic drag, which affects how much energy your engine has to exert to continue moving the car forward. During vehicle testing to establish mpg, cars and trucks are assumed to be carrying 300 pounds total, including both passengers and items. For many drivers, this isn’t a realistic expectation for the load weight. Checking user-reported mpgs can help you determine what your own mpg will look like according to your lifestyle, as compared to those who self-report.

Driving to Maximize Fuel Efficiency

Gas mileage is most efficient with consistent, even driving habits. Frequent acceleration and braking can actually waste gas. It lowers your mileage by anywhere from 10% to 40% on streets, and from 15% to 30% on freeways. Short trips are less efficient because they don’t allow your engine the chance to warm up to its full abilities. Some of these circumstances may be outside your control, like the weather, your cargo, and the types of roads you need to use. Driving on unpaved roads or up steep inclines decrease efficiency because your engine has to work harder. Four-wheel drive also uses more gas than a standard two-wheel drive. Efficiency decreases at speeds over 50 miles per hour. In general, every 5 mph over 50 burns fuel at a rate that adds $0.20 per gallon. That means driving at 60 mph adds on about $0.40 per gallon.

Easy-to-Use Heavy Duty Trucks

Easy-to-Use Heavy Duty Trucks

The 2019 Chevy Silverado is designed to cut an intimidating figure as a workhorse while still being easy to use and pleasing on the eyes. It has several features to help offset its large size and let drivers navigate with precision. It makes the truck user-friendly even as you push it to its limits. For example, towing/hauling mode communicates to the transmission that a heavy load is present to avoid cycling through shifts in transmission. StabiliTrak helps keep the trailer under control by employing the truck’s brakes and, if present, trailer brakes when it senses swaying. Hill Start Assist takes away that moment of doubt when you switch from braking to accelerating on steep grades. It holds the brakes for a few seconds longer to prevent you from rolling backward.

Added Style and Comfort 2019 Chevy Silverado 2500

Just because your truck is a workhorse doesn’t mean you have to be one, too. The 2019 Chevy 2500 features all the modern amenities you’ve come to expect from any vehicle.
