Simply put, modern engine technology is amazing. Engineers have figured out how to extract loads of power and torque from relatively small displacement and low cylinder counts, as evidenced by the turbocharged 2.7L L3B inline four-cylinder found in GM trucks like the Chevrolet Silverado 1500 and GMC Sierra 1500. However, GM appears apprehensive to use the term “four-cylinder” when describing the engine, which is perhaps an indication that public perception hasn’t quite caught up to the realities of modern technology.
Looking over the terminology and wording used for the Silverado and Sierra GM trucks, including each respective vehicle’s website and various marketing materials, nowhere is the L3B engine referred to as a “four-cylinder.” Rather, GM seems intent on referring to it as simply “2.7L Turbo” wherever possible.
Which raises the question – why?
It’s possible the reluctance is due to certain customer perceptions of what a four-cylinder is “supposed” to be, and how those associations are misaligned with the muscle-bound image of GM trucks. Of course, it bears mentioning that those perceptions aren’t necessarily justified when looking at the actual specs offered by the turbocharged 2.7L L3B inline four-cylinder. For example, output is rated at 310 horsepower at 5,600 rpm and 348 pound-feet of torque at 1,500 rpm, which is more than adequate for light-duty GM trucks like the Silverado and Sierra. Output is routed to the wheels via an eight-speed automatic transmission.
For reference, we’ve listed the L3B engine availability in the charts below:
|WT||Custom||Custom Trail Boss||LT||RST||LT Trail Boss||LTZ||High Country|
- A = Available
- S = Standard
- N/A = Not Available
So then, dear reader, is the reluctance to call the L3B engine a “four-cylinder” when referencing its usage in GM trucks justified? Let us know your thoughts in the comments section.
