It’s a question us here at GM Authority have mulled over once before, so we’re bringing it to the table for you all.
The 4.3-liter Ecotec3 V6 LV3 succeeds the Vortec line-up of small-block engines, including the previous 4.3-liter V6 LU3. The LV3 V6 makes do with a host of upgraded technology to ensure fuel efficiency, and power, such as variable valve timing, and cylinder deactivation.
Derived from the fifth-generation small-block program, it’s essentially a 5.3-liter small-block V8 minus two cylinders. But, the V6 produces a healthy 285 hp and 305 lb-ft of torque. And it would fit easily under the hood of a Chevrolet Tahoe, Suburban, or GMC Yukon for that matter.
GM’s true SUVs carry a lot of weight with them, and currently may only be had with the 5.3-liter V8, save for the Cadillac Escalade and GMC Yukon Denali, which both receive the top end of the spectrum: the 6.2-liter L86 V8. And both of those powertrains scoot the SUVs around briskly, never feeling underpowered.
The 4.3-liter V6 could draw a crowd to the rekindled SUV love affair, as gas prices stay relatively cheap across the greater 48 states. But, they may also feel sluggish, as they compensate for added mass not found in their truck counterparts.
Do you think it would be a smart move to offer the 4.3-liter V6 as a base engine for Chevrolet and GMC’s SUV portfolio? Or, should the engine stick with the truck crowd? Let us know in the poll, and sound off in the comments below.
