Just yesterday, Chevrolet finally announced one of the highly-anticipated 2019 Silverado engines – a 2.7-liter turbocharged inline four-cylinder motor with a Dual OverHead Cam (DOHC) configuration.
The result of a clean-sheet design developed specifically for trucks, the petrol (gasoline) motor makes an SAE-rated 310 horsepower at 5600 RPM and 348 pound-feet of torque at 1500-4000 RPM, while introducing a host of advanced powertrain features and technologies.
GM Authority has just uncovered the new motor’s official RPO code: according to Tom Read of GM Powertrain communications, GM’s new turbo-charged 2.7L inline four-cylinder engine is assigned RPO code L3B.
So there you have it: we can now simply refer to the boosted new four-banger as L3B. Short-hand convenience for the win!

Could this be based on (half of) the 5.5L V8 rumored for the mid-engine Corvette?
How about a straight-6 4.0L, 465HP 522TQ, that would be a good truck motor!
Does it need 91+ to make the advertised power? Yes or no?
Saw a GM engineer talking about it on Youtube – YES – it uses regular gas for the advertised HP/torque figures.
No.
New top engine choice for the Colorado? Seems to outperform the current Colorado V6.
GM says regular in their presser.
RPO (regular production option). Does that mean this Engine will be an option on some other vehicle at some point and time?
As an engine developed specifically for truck applications, it makes perfect sense for it to filter into other trucks – Colorado for example.
Man this is going to make an excellent Tahoe/Suburban/Yukon engine as well! I hope it finds its way there sooner rather than later.
Is that 380 pounds less than the 4.3 V6 correct? That should help handling.
I have read 2 different numbers for the weight differences. There is the 380 number and 80 number. Which is correct?
The new 2.7L 4 cylinder weighs 80lb less the the 4.3L V6, The 2019 Siverado with the2.7L weighs 380lbs less the a similar 2018 Silverado with the 4.3L.
Glad you cleared that up. Had me thinking that if the 4.3 weighted 380 pounds more than the 2.7 it must have been made of lead or spent uranium or some other awful heavy metal.
is the l3b capable of cylinder deactivation
