2019 Silverado V8 Engines: GM Selects Tonawanda Plant To Produce 5.3L And 6.2L Mills

General Motors’ Tonawanda plant in New York has been awarded the job of building the 2019 Silverado’s V8 engines. The plant will build both the 5.3-liter and 6.2-liter V8 engines for the 2019 Silverado, both of which will feature GM’s Dynamic Fuel Management technology.

DFM replaces Active Fuel Management, which would shut down four cylinders in the name of fuel economy. DFM can shut down seven cylinders under the right conditions. The Buffalo Business Journal reported on Monday that the engine production comes from a previous $260 million investment at the Tonawanda plant. The facility also builds four-cylinder and V6 engines, specifically, the 4.3-liter V6 engine also found in the Silverado.

For the 2019 model year, the V6 shifts to only the basic Silverado variants. Meanwhile, a brand new 2.7-liter L3B turbocharged four-cylinder engine takes over volume duty for LT and RST trucks. The 5.3-liter V8 engine remains optional.

Production will likely ramp up toward the end of summer as the 2019 Chevrolet Silverado prepares to launch this fall.

  1. THE TONAWANDA BUILT ENGINES ARE A BRAND NEW TYPE OF 5.3 AND 6.2 LITERS, ACCORDING TO THAT BUFFALO BUSINESS REPORT. THEY ARE DOHC WITH 4 VALVES PER CYLINDER. THE POWER INCREASE WILL BE AT LEAST 10 PERCENT MORE THAN THE OLD DESIGN OHV V8 ENGINES. THE MID ENGINE CORVETTE WILL GET THE NEW DESIGN DOHC 6.2 LITER, BUT WITH TWIN TURBOCHARGERS TO MAKE 800 TO 850 HP. THE 5.5 LITER VERSION IS THE SAME DOHC DESIGN BUT ONLY FOR THE CAMARO. THE 5.5 VERSION IS NOW BEING USED IN THE 2018 IMSA SPORTS CAR SERIES IN THE PROTOTYPE CADILLAC DPi.
