Chevrolet is adding a four-cylinder turbocharged engine to its all-new 2019 Silverado pickup truck, in hopes of having the well-nigh economical total-size pickup truck for those buyers — a clear minority — who favor high mpg. The 2.7-liter inline-four produces an SAE-certified 307 hp and 348 pound-anxiety of torque.

Chevrolet released a slew of specs and superlatives for the new engine, simply not its fuel economy rating (or towing chapters). That volition come closer to the ship engagement in late summer or early fall. If the 2019 Silverado is to to be the most economical pickup, it will have to elevation the 22 mpg (combined rating) of 2 variants of the Ford F-150.

Less Weight, More Ability Than Chevy's V6

Full-size pickup trucks run 1-2-3 (Ford-Chevy-RAM) in sales amidst the 300 car and truck models sold in the Us, totaling two million of the 17.2 1000000 vehicles sold last year. They're a drag on each automaker's Cafe (corporate average fuel economy) ratings. Chevrolet'due south bold motility to make pickups more economical was to add an inline-four to go forth with its V6 and V8 gas and diesel engines.

Information technology weighs lxxx pounds less than the four.3-liter V6 gas engine in some current Silverados; that V6 produces 285 hp, 305 lb-ft of torque, and gets 18 mpg city, 24 mpg highway for a two-bike-drive pickup. The turbo four will accelerate to 60 mph in vii seconds or less. It was designed for truck applications only and won't show upward in Chevrolet rider cars. GM said "it is very possible" the turbo-four will eventually supplant the V6 in pickups.

The engine uses double overhead camshafts, continuously variable valve time, and Active Fuel Direction (cylinder deactivation), stop/start technology, an electric (not engine-driven) water pump, variable-pressure level oiling system, active thermal management to go the engine warmed upwardly quicker, and an integrated exhaust manifold that's role of the cylinder head assembly, also to warm the engine faster. The ii.7-liter turbo has an unusually long stroke — the distance the piston travels up and downward within the cylinder — of iv.01 inches (102mm) to provide a high compression ratio (10.0:1) and improved combustion, GM says.

"It punches above its weight," says Tom Sutter, chief engineer for the new engine. In addition, Tim Herreck, executive primary engineer of full-size GM pickups, told Automotive News, " We're going to merits that we're the highest fuel efficiency vehicle and what it means for our customer and the value we give back to our customer." Herrick and GM later walked dorsum the comments, clarifying that the GM pickup lineup will be "very competitive in fuel efficiency," noting EPA testing is not yet complete.

This is the first full-size pickup truck with a iv-cylinder gasoline engine. It will be the standard engine on the 2019 Silverado RST and LT trims. It will likewise on the like GMC Sierra pickup. Several midsize pickups, including the Chevrolet Colorado, accept four-cylinder powerplants already.

Variable Cylinder Engines for Pickups

The next generation of Chevrolet, along with GMC, pickup engines will all have either Agile Fuel Management, which runs on all or half the cylinders, or Dynamic Fuel Direction, which can scale dorsum to just 1 or ii cylinders running, working from 17 operation profiles.

Sixty percent of the time, they'll be running on less than all cylinders. Chevrolet will offer half-dozen powertrain configurations in 2019: the four-cylinder gasoline turbo, a Duramax iii.0-liter inline-half-dozen turbodiesel (also new), the 4.3-liter V6, and 3 V8 engines. The V8s will account for 90 percent of sales, with the 5.iii-liter V8 solitary accounting for 80 percentage of sales. The 2019 5.3-liter volition have Dynamic Fuel Management (variable cylinder shutdown), variable valve timing, and gasoline direct injection.

Chevrolet sold 585,864 Silverados last twelvemonth, 2nd only to Ford F-150, and GMC sold another 217,943 Sierra full-size pickups. While Ford went to an aluminum body to cutting flab from the current F-Series, Chevrolet remained with a steel body and still managed to lose 400 pounds in the 2019 Silverado.
