GM’s new turbocharged I-4 “truck motor”
I was perusing through a local Chevy dealer’s website when I noticed a New 2019 Silverado 1500 had an I-4 2.7 liter turbo charged engine. I don’t/wouldn’t tow ALOT of weight, but am rather skeptical of the whole concept. Regardless of what horsies it’s producing, it seems like a little engine for a heavy truck. I could see it in the Colorado or an SUV.
It’s producing 310 horsepower and 348 lb/feet of torque at 1500 RPM. It has driver selectable start stop technology as well as active Fuel Management. Does anyone on here have one of these that can give some real-world performance and economy data? It appears the dealers around here are putting the 5.3’s and 6.2’s in the more expensive trucks, with the LT’s having the I-4. http://gmauthority.com/blog/gm/gm-engines/l3b/ |

There was a lot of chatter about this engine when the numbers went public earlier in the year. The torque and HP is better than most V6’s and some older V8s.
The puzzling aspect is that primary purpose of a small displacement, turbocharged engine is improved economy. The EPA numbers don’t support that result. You can get a V8 with better EPA numbers. https://www.fueleconomy.gov/feg/Powe...do&srchtyp=ymm |

Just guessing, but would the I-4 integrate with electric motors easier?

I believe that 310/348 power rating is higher than the 2010 5.3l V8 I had, so it should be more than adequate to move the truck and tow fishing boats.
Different times these days, "no replacement for displacement" rule of our youth is gone. |

I remember seeing an interview way back where Victor Edelbrock said the ultimate goal was 1hp per c.i. of displacement. Even with naturally aspirated engines, that goal has been far surpassed.

You’d think that these concerns would have died long ago. How long has Ford been using their turbocharged engines in trucks? The 3.5 version has to be out for 10 years?
Ford has a 2.7 turbo V6 that they have used with success for many years as well. I know the EcoBoost was supposed to be better MPG (which hasn’t really planned out), but the driving experience is so much better with a turbo engine. I’m not a Ford guy. I am MOPAR to the core. But I also need a full size SUV. This year, I changed from a Yukon Denali XL with the 6.2 to a Expedition Max with the EcoBoost. The turbo V6 is a better driving (and towing) engine. I’m sure that GMs 2.7 turbo should give similar performance advantages. Sent from my iPhone using Tapatalk |

Have you seen this, supposedly based on the Ram 1500? https://www.autoblog.com/2019/11/25/...agoneer-spied/

[QUOTE=Custom Eyes;6375056]And continually with issues. Declining numbers of issues with the Egoboosts, but still there and many directly related to the turbo charged design.[/QUOT
What are you talking about this time? |

Read that earlier today. I hope they finally build it. Seems like it has been “in the works” for 10 years. If they do build it, I would likely trade the Expedition in. Sent from my iPhone using Tapatalk |
