The LV3 V6 engine is produced by General Motors for use in pickup trucks. It is part of GM’s 5th-generation Small Block engine design that’s named EcoTec3 in pickup trucks, replacing the 4th-generation Small Block engine family known as Vortec. The launch of the EcoTec3 engine line, including the 4.3L V6 LCV, coincides with the launch of the all-new 2014 Chevy Silverado and 2014 GMC Sierra.



Weighing in at 450 lbs (203 kg), the V6 EcoBoost is the daddy of power and performance. It displaces 3,496cc, has a 60 degree layout, a 92.5mm bore and a 86.7 mm stroke. It uses two Honeywell-Garrett GT15 and replaces small-block V8 like a charm. The first time it was previewed was a Lincoln MKR concept where it was rated at 415 hp.

It’s power output is either 355 hp (265 kW) in the case of models like the Lincoln MKS, MKT and Ford Fusion or 265 hp (272 kW) offered by two performance models with tweaked exhausts, the 2013 Ford Explorer Sport and the 2013 Ford Taurus SHO. All these cars have the same torque levels, 350 lb-ft (475 Nm) available at 5000 rpm, though the Ford F-150 pickup gets 420 lb-ft (569 Nm) which is available from just 2500 rpm.

The big question for GM in truck wars is how the counter this Ford powerhouse. They either have to drop the Twin Turbo Cadillac motor or bolt on an eton on the 4.3 Liter.

an Eaton is the probably the best way for GM to bring big bang to the table with a cost advantage.

I would call it ECOTEKKBOOST. Know what I mean?

GM seriously needs to consider boosting this motor. Ford is just kicking them in the behind.. and they still could have cylinder deactivation with something like 420 hp and 420 pound feet of torques out of it.. and probably make an extra 4 grand from each truck with it..

It would be cool as hell, but GM has good engine lineup in the trucks. No need to change anything in that regard.

Holy ****, we're back to GM needs a TTV6 in their trucks again? I thought this was put to bed when they developed their V8's to be as good as the other guy's TTV6's?! What the hell happened? Why is this being talked about again?!
Its not that they do not have great engines.. they are simply being killed by the ecoboost propaganda.. the propaganda is where its at. A Supercharger on this motor would give them something to work with in the propaganda war and charge more while doing it..

Plus they could probably make more power than Ford easily from it. Looking at the 650 HP 6.2 liter from corvette, a super charger on this motor using the same technology as the corvette can get them perhaps to 450/450.. that would be staggering power without much of a penalty in day today cycle EPA ratings

They aren't getting killed by anything, good lord, drama queen much? GM trucks and SUVs are flying off the lots and with MUCH higher ATPs to boot. And guess what, everyone is bypassing the V6s for the V8s. GM is filling Fort Knox with gold bullion with them. They don't need to muck it up by tinkering with gimmicks no one wants. Let the "I-don't-need-a-truck-but-want-to-feel-more-manly" poser buy the other guy's ecobust. I'd much rather be associated with REAL trucks with REAL owners thank you very much.

but supercharger has terrible fuel economy!
Given the corvette Supercharged still has cylinder deactivation, this can help mitigate fuel economy.. Think about it. The Ford 3.5 puts out 365 horse power and 420 foot pound of tourque, Chevrolets 5.3 puts 355 horses and 383 lb.-ft. of torque. Basically, Ford can sell that all day...

The 6.2L should be supercharged for an Escalade V or a Denali X package.

But the new 4.3L should be in the Lambda platforms, and a SC version for upper trims.

The forced necessity aka as the EB3.5 / F150 has seen it better days.

The most important feature of which was a Chrysler in ruins and a GM tied up in knots via their deliberately disruptive BK.

Chrysler was supposed to end up around a 5 % total marketshare on the way to oblivion, and GM was supposed to be at or below 15.x % while trending ever lower.

Ford was supposed to around 18 - 19 % as was Toyota.

'Somehow'..... the non EB trucks from GM and Ram are the bigger part of why all that forecasting - for the 2012 - 2014 timeframe is so laughable today.

Instead of the power of. V8 with the economy of a V6, like Ford advertises, GM should say directly "The fuel economy of a V6, but the real V8 when you need it. Get the real thing, not the imposter!
A sc V6 sounds fine where the V8 doesn't fit

Yes, GM needs to Supercharge the 4.3L V6 and would not be surprised if it got better MPG than the 3.5L Eco-Boost and be competitive with the new 2.7L. GM could also offer smaller size V6's if they were superchaged.

As a rough guide (power ratings cannot be determined by basic math since smaller engines do not always "match" what is "calculated")

Using the 6.2L 650/650 as the multiplier and assuming no losses in power GM's V6 would produce

3.0L S/C 315/315
3.3L S/C 346/346
3.5L S/C 367/367
3.8L S/C 398/398
4.0L S/C 419/419
4.3L S/C 451/451

It should be remembered that S/C engines tend to produce strong torque numbers quickly at low RPM's so make good truck engines and a larger displacement reduces the need to "get on it" that is sometimes required with Eco-Boost engines and was my experience driving one.

Supercharged engines do not have "Turbo Oil Coking" issues but do lose more power than Turbo'd ones, OTOH they are a easier to "Package" under a truck hood that generally has more vertical underhood space and do not require complex exhaust piping.

Another option would be using a smaller displacement V8 which could be used for HD trucks and those (using some "classic" Small block sizes) could potentially produce

4.3L S/C (265) 451/451
4.7L S/C (283) 493/493
5.0L S/C (302/305) 524/524
5.3L S/C (Current) 556/556 (same as "old" CTS-V 6.2L)
5.4L S/C (327) 566/566
5.7L S/C (350) 598/598
6.0L (Current) 629/629

Some strong Torque numbers even for the smaller engines, be interesting to see if GM expand's it's Supercharged engine line.

Biggest advantage of using a Supercharged 4.3L is that few if any changes are required to engine mounts and other components for it to fit. Should be plenty of underhood clearance and intercooler plumbing is not that complex.

Another option would be to go the turbo route as well which would add approx 30 to 50 HP to the estimated supercharged 4.3L or 480 to 500 HP and take advantage of the engine already being "fitted" to the vehicle.

Even better, GM should do both and mix and match NA V6, S/C V6 and Turbocharged V6 engines in a variety of sizes for different applications, same for the V8 Line with NA V8, S/C V8 and Turbocharged V8.

GM's 90 Degree V6 and V8 engine lineup can offer a substantial amount of flexibility and be matched to 6-Speed, 8-Speed and 10-Speed automatics or a variety of Manual transmissions and be great to see GM expand offerings. GM can also offer these new engines in Aftermarket Performance "kits" to upgrade older GM models.
