The pick up truck wars just heated up a bit today with the announcement that customers will have the option of purchasing a 2019 Chevrolet Silverado with a turbocharged four cylinder. The engine will also have cylinder deactivation technology, which will allow it to run on only two cylinders in low demand situations.
Total displacement of this new engine? 2.7 liters.
That last bit of information is what really piqued my interest, because Ford currently produces the 2.7 liter EcoBoost V6. It’s entirely possible GM did the research and determined that amount of displacement ideal for their purposes, but I’m also betting they decided to use that figure to compare the engine directly against the Ford unit. GM seems to be betting that sometimes there is no replacement for displacement, but cylinders can be eliminated with no issues.
|4.3L V6||285 HP||305 Ib-ft.|
|2.7L I-4||310 HP||348 Ib.-ft.|
|5.3L V8||355 HP||383 Ib.-ft.|
|6.2L V8||420 HP||460 Ib-ft.|
The new turbo four roughly mirrors it’s 2.7 competitor as it pertains to the contemporary Silverado lineup. Like the EcoBoost, it will have broad availability in less expensive variants of the Silverado, and it also replaces the 4.3 liter V6 in certain trims, which is similar to what Ford did with its 3.3 liter V6. Currently it has not been confirmed for the GMC Sierra, but odds are that its availability will extend to that nameplate as well, as GM is thinking of replacing all of its V6 pick up engines with the four cylinder at some point in the near future.
Automakers have introduced quite a few innovations into the American full size pick up segment over the last ten years. Ford went full throttle towards turbocharged engines and aluminum construction, while FCA opted for a 48 volt mild hybrid system. And there’s also the diesel renaissance as well. GM’s fuel saving technology has been less visible up to this point, but that is about the change with their new turbo four.
