Engine & Performance
For 2020, GM made some huge waves in the light duty diesel market by introducing their first late model, inline diesel engine in a 1/2 ton 1500 pickup. Yes, we understand the diesel LUV was truly Chevy's first go, but again, we're talking about late model vehicles. The LM2 Duramax engine features an inline, six cylinder arrangement boasting 277 horsepower and 460 foot pounds of torque. Now this is pretty respectable for a half ton truck, but where the payoff really lies is in the rated 26 highway MPG's.
Many of the specifications of this 3.0L are quite similar to that of the larger displacement diesels, featuring such components as a variable geometry turbo (VGT), high pressure, common rail fuel system, water-to-air intercooler, 10 speed automatic transmission (Hydra-Matic 10L80), and many other items. Improvements to the emissions system have been done as well. This engine features a low pressure EGR system that supplements the existing high-pressure system. This improves efficiency and performance. Exhaust gases are drawn from after the diesel particulate filter and re-introduced after the compressor inlet. An electronically controlled valve activates the low-pressure EGR system, the engine burns exhaust gases that have already passed through the filter. The end result is even lower overall emissions.
Now, the question at hand, what can you benefit from the aftermarket? How about added power to get you over that 300 rear wheel horsepower mark? How about even better fuel economy or added lift for larger tire fitment? If you are unsure of what parts are right for you, don't hesitate to give us a call and we would be happy to assist.
