2014 Chevrolet Tahoe Caught Testing in Michigan

New Fullsize SUVs Will Get 8-Speed Transmission, Direct-Injection V-8's

June 26, 2012

By: Edward A. Sanchez

Long the leader in the fullsize SUV segment, General Motors isn't letting any grass grow between its toes with its next generation of fullsize SUVs. These photos of a cladded 2014 Chevrolet Tahoe were snapped just outside GM's proving grounds. Interestingly, the badge on the grille underneath the mesh covering is a prominent oval, indicating GM may have been hoping to fake-out spy shooters into thinking it's a Ford. However, a Chevrolet bowtie can be seen on the wheelcaps under the tape and there were Toyota Sequoia and Ford Expedition comparison vehicles accompanying the prototype.

Since the addition of a six-speed automatic to the lineup in 2009, the GMT900-series SUVs have been near top-of-class in terms of fuel economy. Reports of an eight-speed automatic transmission and direct-injected fifth-generation small block V-8 power for the new Tahoe (known internally as K2UC) and the Yukon(K2UG) indicate GM intends to remain a class leader in this increasingly important area. Although the eight-speed is certainly in the cards at some point, availability constraints may have the big SUVs launching with six-speeds.

In what may also be a concession to efficiency, the test mule appears to retain the GMT 900's solid rear axle. Most fullsize SUVs, including the Expedition and Sequia, have independent rear suspensions, which are favored by some manufacturers for allowing greater flexibility in interior packaging. However, the marginal frictional losses inherent in CV joints of an IRS may have outweighed the potential benefits. In addition to less mechanical drag, solid rear axles are generally considered more robust for towing and hauling duties.

New all-aluminum small block V-8s equipped with direct injection are a given, likely in the same displacement as the current 5.3 and 6.2-liter fourth-generation Vortec engines with a possible 5.5-liter variant. GM may still have some surprises up its sleeves, however -- some reports have suggested a diesel option could be offered along with a hybrid model, though the GMT900 hybrids haven't set any sales records. Also unknown is whether GM will field a turbocharged V-6 option to counter Ford's popular EcoBoost powertrain, which may soon be offered in the Lincoln Navigator.

GM clearly has high hopes for the new Chevrolet Tahoe, Suburban, GMC Yukon/XL and Cadillac Escalade models, having invested a total of more than $500 million in its Arlington, Texas plant since 2009. GM is overhauling its entire fullsize truck and SUV lineup within the next 18 months and the new SUVs are expected to be second or third in line, behind the new Chevrolet Sliverado and GMC Sierra 1500, with the 2500 and 3500-series HD trucks and fullsize SUVs following.

Hopefully this means the front clips are shared between the pickups and SUVs once again, as before the 900s. What I can see looks good so far. Maybe this will mean the next Yukon won't look like a bullfrog peeking over the surface of the pond.

Good catch, Mr. Doane.

I've long thought the current Yukon would have looked better w/ the Sierra front end. But I do prefer the Tahoe/Suburban front end over the Silverado.

I am thinking they hung the body low for Aero. This may be some hybrid model as they use a similar lower air dam.

I wonder if they will use more under shielding as some of the cars are to clean up the under body air management.

Are these trucks truly ALL NEW? I am doubting it because the muffler looks exactly like the current Tahoe... is this just a rebody, or is it road-to-roof?

Well, some dirty bits like mufflers probably carry over between generations..and remember, these are photos of prototypes..

I am getting a very GMT-400 vibe from this. It appears to have much tidier dimensions than the current Tahoe, and the front seems more upright. Maybe GM is holding to its promise to put the full-sizers on a diet.

I agree wit z. Piercing the vinyl wit mine eyes, I see a late model 400 facial structure wit tweaks for modernity. This is gonna be lovely, familar and just right, I tink.

I expect the interior to be close to the same size but I think the outside will shrink a little. They will lose weight, it may not be much but they will lose some.

I totally agree and I think most people also, the Chevy Suburban/Tahoe should have shared it's front end with the Chevy Truck.

GMC should have ditched the but ugly Yukon nose for the GMC truck nose.

This way both truck and suv have family design language that is best and looks freakin awesome!

I am excited about the new Full Size SUV Family. I just hope they realize that their is a market for having a diesel in the Suburban/Yukon XL line.

Due to Gov Regs, the Whole auto industry has been on a bloat diet over the last 20 years. Time to go on a Diet and loose that mid section! :)

Oh hell you have not see weight loss yet. By 2025 they will be cutting things we wished we would have never wanted to see. Some model lines will vanish because of the regs. This is not my opinion but something stated by a GM engineer.

Unfortunately, ever-tightening regs leave very few areas left for slimming, esp when other areas will be mandated to get fatter. The weight scenario in modern cars is pretty tight as it is- sheet metal -what there is of it- is paper thin, glass is thinner than ever, powertrains are largely AL already, and plastics continue to spread & spread & spread.

What remains is large-scale moves to lighter alloys / CF, and not much else to offset more & more wiring.

Future weigh loss will be incremental changes, don't expect anything radical... unless a manufacturer builds an illegal MinimalistKar.

I expect some models to go away or be restricted in production numbers. This will drive their cost up. You can go to lighter alloys but that only works to a point. I am affraid we will be seeing more and more smaller vehicles coming and less and less larger ones being built and even then not at very affordible prices.

It is sad to day but Vehicles like the new Buick Encore are just a peek at the future of the average type vehicle.

The only thing that could save the day is some kind of breakthrough in batteries or hybrid technology that we do not have as of yet. But the MFG still have time and a few tricks to play. Either way it will not be cheap or easy to meet the present standards. It may come down to a election issue at this rate in a few years. A canidate could run on a statment he will give us back larger cars if people get sick of the small boxes.

A given mid-sized, internal-combustion sedan really has almost no 'tricks' left to play. OEMs have been hammering after CAFE for 30 years now. They've tweaked everything there is at one point or another. Even those manufacturers who have a rep for engineering-driven manufacturing have still seen weights increase despite all efforts. The 3-series used to be 2500 lbs, now it's 3500-3600 & the 1-series is 3200.

It will take a radically different type of vehicle (perhaps the GM 'skateboard' concept, with a bolted-on plastic body shell??) to change the weight picture on the same footprint, but don't expect that within the next 15 years.

CAFE is ok when both sides work together but as in most goverment issues it is doomed because one make demands with no care to see how the otherside could accomplish it.

The key will be around2017-18 the automakers want to sit down with the goverment and see where they stand. All they are asking for is a review and adjustments to the future goal.

It should be interesting to see what happens.

Politically, I think the republicans may win big in November, and if they do CAFE could go the way of the dodo bird.

I'd be surprised if the republicans won big.

And I'd be even more surprised if they sent CAFE to the circular file - they are just as wrong-headed about this as the democrats are.
