FleetOwner Blog Highlights 2020 Chevy Silverado's 33 MPG Highway EPA Rating

Touting the highway fuel efficiency of a sedan but delivering the capabilities of a full-size truck is an amazing accomplishment, and one that we are so very proud of the 2020 Chevy Silverado 1500 for nailing down! Brandishing the new 3.0-Liter Duramax turbo-diesel engine, the EPA has rated fuel economy at 33 mpg highway and 23 city in rear-wheel-drive models. The recent FleetOwner blog highlighted just how good the new Silverado model is as it brandishes an SAE-certified 277 horsepower and 460 lb-ft of torque, while also boasts a towing capacity of up to 9,300 pounds and a max payload of 1,870 pounds. These two hefty traits can easily meet the day-to-day demands of about 90 percent of light-duty truck buyers.

The engine onboard utilizes state-of-the-art technologies to put to optimum use every single drop of fuel as well as making use of changes to its architecture to make the Silverado larger, more aerodynamic, and lighter than before. This is the first light-duty diesel offered in Chevy's arsenal since 1997, and our very first inline-six for the full-size, light-duty category. Every bit of expertise we have thoroughly gleaned within the realm of diesel was employed by engineers to assure that the all-new 3.0-Liter Duramax Turbo-diesel engine offers the strong performance levels and long-lasting durability that our hard-working customers need every day.

The key components are made up of durable material such as iron cylinder liners within the aluminum engine block, a forged steel crankshaft, and blended silicon/aluminum pistons that provide greater heat resistance and reduced expansion. During development, the engine underwent extreme real-world and simulated testing to make sure that the highest standards of performance and durability were achieved in the finished product. This is an engine that provides an inherently balanced configuration for low noise and vibration characteristics. It features an aluminum block for weight reduction, an 84 mm x 90mm bore and stroke, four valves per cylinder and dual-overhead camshafts.

There's a new active thermal management system onboard that provides quick warmup for propulsion components, ultimately making for more efficient operation. The exhaust brake is available in tow-haul mode and can provide additional driver confidence when towing, a rugged and dependable duty that the 1500 is known for excelling at. The driver-selectable stop/start technology enhances fuel economy by shutting off the engine at stoplights and other increment situations, which is a massive help in saving fuel. When this very useful and game-changing feature is engaged and the driver takes their foot off the brake, the engine automatically restarts. The new diesel option does a first-rate job of rounding out the all-new Chevy Silverado 1500 offerings here at Chuck Hutton Chevy of Memphis, where we hope we see you for a test drive during the fall season!
