For over a century, Chevrolet has been producing some of the best trucks on the market. Originally starting as the C10, the Silverado has been a well-loved truck by many over the ages. At the beginning of 2019, Chevy debuted the fourth-generation Silverado. Completely redesigned, the 2019 Silverado may just be the best yet. Although the 2019 Silverado has a longer wheelbase than the previous generations, it weighs considerably less. Shedding nearly 450 pounds for certain models, the new Silverado is constructed from mixed materials including lightweight aluminum and high-strength steel. With eight different trim levels, Chevy’s goal was to create a truck for everyone. Six different 2019 Silverado engines are also available in addition to the multiple trim options. Tim Asoklis, chief engineer for the Silverado 1500, commented on Chevy’s dedication to inclusion, stating:
“A major focus of the next-generation Silverado is expanding the range of choices. With all-new engines and a broader model range, there’s a Silverado for everyone, whether you’re buying your first pickup or your tenth.”
2019 Silverado Engines
- 4.3L EcoTec3 V6
- 2.7L I4 Turbo
- 5.3L EcoTec3 V8 with AFM
- 5.3L EcoTec3 V8 with DFM
- 3.0L Duramax I6 Turbodiesel
- 6.2L EcoTec3 V8
A 3.0L Duramax inline six-cylinder turbodiesel along with a 2.7L turbo I4 are both additions to the engine lineup. In addition to the two new 2019 Silverado engines, several of the previously offered engines received some much-needed updates so they are more efficient than before. For the 2019 Silverado, Chevy is introducing an industry-first technology dubbed Dynamic Fuel Management, a progression of the Active Fuel Management system that Chevy introduced in 2005.
AFM vs DFM
Active Fuel Management, or AFM, is a cylinder deactivation system that uses software to control hydraulic valves in order to turn off the cylinders when full power isn’t needed. The system turns the cylinders back on when full power is required. So in light-load driving conditions, only half of the cylinders are active, which would be four cylinders for a V8 and three cylinders for a V6. Since fuel delivery is shut off when activated, AFM enhances fuel efficiency. With this system, you can opt for a larger engine but achieve better fuel efficiency. If you need to use full power and have all cylinders firing, they are always there when you need them. For the first time, Chevy will be implementing this technology on a four-cylinder engine — the new 2.7L turbo.
Rather than deactivating half the cylinders, Dynamic Fuel Management, or DFM, uses 17 cylinder patterns in order to enhance power delivery and increase efficiency. A sophisticated controller determines the number of cylinders needed based on driving conditions, recalculating 80 times per second. Because DFM is torque based and has greater variability, you can achieve better fuel economy without feeling a loss in power.
4.3L EcoTec3 V6
The starting engine that is standard on several base models for the Silverado is Chevy’s 4.3-liter V6 engine. With AFM and a 6-speed automatic transmission, the engine produces 285 horsepower and 305 lb.-ft. of torque. Other features of the 4.3-liter engine include FlexFuel capability, variable valve timing, direct injection, and an aluminum block construction. The 4.3L EcoTec3 V6 engine first became available for the third-generation Silverado in 2014. The 4.3L engine will still come standard on the WT, Custom, and Custom Trail Boss.
2.7L I4 Turbo
Replacing the 4.3-liter V6 as the standard engine option for the Silverado LT and RST trim levels, the 2.7L turbo engine is a powerful little beast. Packing 310 horsepower and 348 lb.-ft. of torque, the 2.7L is significantly lighter than the 4.3L, weighing 380 pounds less. Chevy claims that the new turbo engine will outperform Ford’s 3.3-liter V6 and Ram’s 3.6-liter V6. Capable of going from 0-60mph in less than 7 seconds, the new Silverado turbo is quick. The 2.7L turbo engine uses the AFM technology so it’s not only fast, it’s efficient as well. It’s the first time that Chevy has used AFM on a four-cylinder engine. Equipped with a dual-volute turbocharger, the engine is capable of producing higher torque at a lower rpm and has enhanced responsiveness. Active Thermal Management technology allows the turbo to have targeted heating and cooling, so the engine can cool off when needed or heat up faster. The turbo is paired with a Hydra-Matic 8-speed automatic transmission. The new 2.7L turbo is certainly one of the most exciting 2019 Silverado engines that will be available.
5.3L EcoTec3 V8
For Chevy’s 5.3-liter V8 engine, they offer two different versions, one with AFM and one with DFM. The 5.3L V8 with the Dynamic Fuel Management is now the standard engine rather than the 5.3L V8 with AFM, although that is still available for certain trim levels. In comparison to AFM engines, the 5.3-liter with DFM uses less than eight cylinders for a larger majority of the time than the AFM version, which will help save gas. The 5.3-liter V8 engine produces 355 horsepower and 383 lb.-ft. of torque, paired with the Hydra-Matic 8-speed automatic transmission for the DFM version and a six-speed transmission with the AFM version. The engine is equipped with stop/start technology that helps increase fuel efficiency.
3.0L Duramax I6 Turbodiesel
Supposedly nicknamed the “baby Duramax,” Chevy’s new 3.0-liter turbodiesel inline-six cylinder engine will compete directly with Ram’s 3.0L EcoDiesel and Ford’s new 3.0L V6 PowerStroke. Although the power numbers haven’t been revealed yet for the turbodiesel, Chevy expects it to surpass the competition. Considering the 3.0L EcoDiesel for the Ram 1500 produces 240 horsepower and 420 lb.-ft. of torque while the 3.0L PowerStroke puts out 250 horsepower and 440 lb.-ft. of torque, the 3.0L Duramax will probably fall in line with those or exceed them. The 2019 Silverado diesel will be paired with a 10-speed automatic transmission and feature start/stop technology.
6.2L EcoTec3 V8
Chevy’s popular 6.2L EcoTec3 V8 engine is getting an upgrade for the 2019 Silverado. Now using DFM technology rather than AFM, the V8 engine will be paired with the Hydra-Matic 10-speed automatic transmission. Producing a hefty 420 horsepower and 460 lb.-ft. of torque, the powerful V8 engine will be available for the LTZ and High Country trims.
