2014 engine HP, torque, and fuel economy ratings . . .

[Lloyd-TX]

When the heck will this info be released?

I thought that I had heard this month, but there are only a couple of days left in January . . .

Thats a really great question. For what its worth(I can't imagine much) when I was at the Detroit NAIAS I spoke with the gentleman who was there doing the talking points on the new GMC truck and he was told they would be releasing those numbers sometime in February. The are waiting for the SAE certified numbers... Again I would take this info with a grain of salt, but who knows maybe this guy somehow knew what he was talking about.

Remember who generates the SAE numbers and the EPA test results - the car companies themselves. They run the tests and send the results to SAE and EPA, where the numbers are accepted.
The EPA test VERY FEW cars and trucks and mostly accepts the numbers given to them.
So GM knows the SAE and EPA numbers RIGHT NOW and chooses to release them when they want, and not before. You will know those numbers when GM decides to release the information. They may hint at the numbers by calling them preliminary, like they are doing on the hp and tq of the LT1, but we will just have to wait for GM's actual announcements.
Edit: if you care to look this up, the car companies run the tests in accordance with SAE procedure J1349. To comply with SAE standard J2723, there must be a SAE-certified third-party observer present to observe all testing procedures.

Dr. Show-Me doesn't know what the He Double L he's talking about. #1. The EPA and ONLY the Enviromental Protection Agency puts the fuel economy numbers on vehicles. The car companies have NOTHING to do with the EPA ratings. Sure, GM probably did their own internal tests but are waiting for SAE certification before releasing the Horsepower and Torque ratings. The total B.S. that people spew on this board with absolutely NO FACTUAL basis or information to back up their ignorant statements are way to many to count. So, let's get one thing straight, the listed fuel economy rating on all NEW cars and trucks are done by the EPA and not the car companies. If the car companies were in control you would see alot more over inflated fuel economy numbers.

GM will release the horsepower and torque ratings on their new engines after the SAE Certification tests are done and not until then. Capish???

Right from the DOE itself. All figures are self reported. Only 10-15% are retested by EPA for verification. The Doctor is correct.

For SAE certification, the manufacturer pays for the test, and not all manufacturers choose to have this certification.

IMO The reason the engine specs and performance numbers have not been released is "They are unremarkable". If the new HP, Torque and efficiency numbers were class leading GM would want that information out as soon as possible. GM knows people will wait to buy if there is something to wait for. The new 2014 K2XX engine numbers are merely "competitive", nothing great or we would have heard by now.

Actually, the EPA does not test all vehicles, that's why there are errors like the Hyundai's recent problem with mis-stated fuel economy happens. The EPA selects vehicle models to test at random, but most vehicles are tested by manufacturers and submitted to the EPA. http://www.nbc-2.com/story/20150075/...ed-gas-mileage "The inflated figures were uncovered by the Environmental Protection Agency in an audit of gas mileage tests by the two South Korean automakers.

Or the fact that we might see a bump of 50 HP and 50 TQ for the 5.3 and GM wants to sell as many GMT900 trucks before they get into the problem of people waiting for the new ones.

You may be right, but it's also possible GM just doesn't want to kneecap sales of the existing trucks while they're waiting for the new ones to reach dealerships.

(EDIT) Or bballr4567 could beat me to the punch.

Last time GM started boasting the ZL1 would make 550+ HP and Trq. They mentioned these figures nearly 1 year before they officially announced 580 HP. Plenty of time for Ford to get to 660 w/ the Shelby. If GM didn't play their hand, who knows, maybe Ford would have stopped at 600?

Good point blaksabb. This is my thought as well. All GM needs to do to early is say that the new 5.3L makes 385 or 390 hp and give Ford the change to make some tuning changes on the 5.0 and one up GM again. As bad as I would like to see the numbers, it is a good thing GM is holding out as long as they can.

Lets remember the new truck is a 2014 that will be available this summer....no need to tip the competition.

What automotive company in their right mind would release final specs this far away from the debut of the Corvette, and K2XX trucks? Because our resident truck expert who has been wrong far more than she has been right thinks the figures are unremarkable does not mean that actual truck buyers will agree.

But they did release a lot of Corvette's specs, especially the engine figures. Although Corvette has no real competition. It's easy to surmise that GM will put in as much as Corvette's power figures in the trucks 6.2. So I'm not sure what cat GM is keeping in the bag...5.3 plays second fiddle to the 6.2, while the 4.3 is the entry level mill.

Truck figures are what they are going to be. Currently Ford has them beat with every engine, so does Dodge, as well as Toyota, and I don't think GM's current engines are bad by any means.
