The wait is over, and we now know exactly the power and torque ratings of the 2019 Silverado engines, thanks to order guides (linked below) first discovered by GM Authority.
|Engine / Metric||Power (hp / kW) @ RPM:||Torque (lb-ft / Nm) @ RPM||Transmission|
|5.3L V8 L84 (new)||355 / 265 @ 5600||383 / 518 @ 4100||8-speed automatic MQE|
|5.3L V8 L83 (old)||355 / 265 @ 5600||383 / 518 @ 4100||6-speed automatic MYC|
|6.2L V8 L87 (new)||425 / 317 @ 5600||450 / 610 @ 4100||10-speed automatic MQB|
|6.2L V8 L86 (old)||420 / 313 @ 5600||460 / 624 @ 4100||8-speed automatic M5U|
5.3L L84 V-8
The 5.3L V-8 is assigned RPO code L84, one number greater than the 5.3L V-8 L83 in the last-gen Silverado (on the K2 platform). The motor makes 355 horsepower at 5600 RPM and 383 pound-feet of torque at 4100 RPM.
The 5.3L L84 V-8 is paired with the GM 8-speed automatic transmission (RPO code MQE).
6.2L L87 V-8
The 6.2 V-8 is assigned RPO code L87, also a number greater than the 6.2L V-8 L86 in the outgoing K2 Silverado. Rated at 425 horsepower at 5600 RPM and 450 pound-feet of torque at 4100 RPM, it’s mated to the new GM 10-speed automatic transmission (RPO code MQB).
Though these new 2019 Silverado engines have roughly the same output of their immediate L83 and L86 predecessors (stay tuned for a comparison), both of the 2019 Silverado engines will likely result in a greater fuel efficient thanks to new fuel-saving technologies like engine auto start/stop, which automatically shuts down the engine at stop lights to conserve fuel, and Dynamic Fuel Management, which overhauls the Active Fuel Management/Cylinder Deactivation technology to allow the engine to work on only one cylinder.
Fuel economy ratings for both engines are not yet available.
Despite the 2019 Silverado order guides only listing these the two aforementioned motors, they won’t be the only 2019 Silverado engines available, as Chevy has confirmed that the “2019 Silverdo will be available with six engine/transmission combinations”.
We already know that the third one will be the all-new inline-six 3.0L Duramax diesel engine. That motor is not listed in the order guides. Additionally, this iteration of the order guides, which were updated April 20th, does not contain information on the base model 2019 Silverado, such as the Work Truck, Custom, or Custom TrailBoss, and it’s highly unlikely that these base models will powered by the 5.3L V-8 L84. Instead, a new base engine will likely be introduced. And something tells us that a boosted mid-level engine to slot above the 5.3L L84 will also become available, as will an electrified/hybrid model.
So in other words, this isn’t the complete 2019 Silverado engine lineup, but rather just a part (exactly 40 percent) of it.
