The twin-turbocharged Ford 2.7L V6 EcoBoost Nano powerplant has been around for a few years now, debuting in the 2015 Ford F-150 and seeing use in the Ford Edge and Lincoln Nautilus, among other vehicles, producing as much as 335 horsepower and 380 pound-feet of torque, depending on configuration. However, General Motors also introduced a revised version of its own 2.7L I-4 Turbo L3B powerplant in conjunction with the refreshed 2022 Chevy Silverado, which makes it more competitive in terms of output compared to the older version, which produced 310 horsepower and 348 pound-feet of torque.

Though both the Ford 2.7L V6 EcoBoost and GM’s 2.7L I-4 turbo engines share the same displacement, the two powerplants are also quite different, aside from the additional two cylinders present in the Blue Oval version. GM’s single-turbo 2.7 features a cast aluminum block and heads, while the Ford twin-turbo 2.7 utilizes compacted graphite iron (CGI) and aluminum, respectively, and the former features direct high-pressure injection and the latter a dual setup of port and direct injection.
In terms of output, the GM 2.7L I-4 received quite a boost in the 2022 Silverado and Sierra – though horsepower remains unchanged at 310, torque shot up to 430 pound-feet. Meanwhile, the Ford 2.7 generates 325 horsepower and 400 pound-feet of torque in the F-150. In GM applications, this powerplant is mated to the Hydra-Matic 8L90 8-speed automatic transmission, while Ford pairs it with the SelectShift 10-speed automatic.
In addition to its use in the Silverado and Sierra, this particular tune of GM’s 2.7L I-4 will also serve as the top range variant in the recently-revealed 2023 Chevy Colorado ZR2, while lesser variants will get the same powerplant, albeit in less powerful tunes.
