If you’re into GM vehicles, and we suspect you are, then you’re probably somewhat familiar with the various GM engine RPO codes, or at least the big ones. You know, like LT1, the naturally aspirated 6.2L V8 equipped by performance models like the Chevy Camaro SS and C7-generation Corvette Stingray, or LT4, the supercharged 6.2L V8 equipped by models like the Cadillac CT5-V Blackwing and Cadillac Escalade-V. However, for the average consumer, these engine RPO codes could be somewhat obscure. Luckily, GM’s new TurboMax branding finally gives The General the recognizability it needs.
With regard to the competition, Stellantis offers the Hemi, while Ford has EcoBoost, both of which hold weight in the minds of consumers. Meanwhile, GM does offer the Ecotec engine branding, but it’s a bit too generic to mean much to consumers.
Compared to Ecotec, the GM TurboMax name conveys muscle and maximum output, which is what you want from an engine brand. For the moment, the new TurboMax name is applied to the high-output variant of the turbocharged 2.7L I4 L3B gasoline engine equipped by the 2024 Chevy Silverado 1500 and 2024 GMC Sierra 1500, but could also be part of an entire engine “family.”
The GM TurboMax name also draws similarities to the Duramax name, which is already well-recognized as a strong diesel engine brand for GM. A few noteworthy Duramax engines include the 3.0L I6 LM2 and 3.0L I6 LZ0, the 2.8L I4 LWN, the 2.8L I4 XLD28 offered in South America, and the 6.6L V8 L5P, all of which could be considered part of the same engine “family.”
So far, the TurboMax name has only been announced as branding for the L3B in the 2024 Chevy Silverado 1500 and 2024 GMC Sierra 1500, but could very well find its way to the 2024 Chevy Colorado and 2024 GMC Canyon as well. At the moment, it’s unclear if the branding will apply to both the Turbo Plus and the Turbo High-Output variants of the L3B engine in the midsize pickups.
Either way, we’ll be there every step of the way to obsess over everything GM, so stay tuned. In the meantime, remember to subscribe to GM Authority for more GM business news, GM technology news, and around-the-clock GM news coverage.
