GM Press Release

 

It’s Official: 2014 Silverado and Sierra Deliver Most Power

New Chevrolet, GMC light duty pickups also deliver best towing capacity in class and strong fuel economy

 

DETROIT – The 2014 Chevrolet Silverado 1500 and High Country and the GMC Sierra and Sierra Denali 1500, available this fall, with a 6.2L V-8 produces an SAE-certified 420 horsepower (at 5600 rpm) and 460 lb-ft of torque (at 4100 rpm), the most power of any pickup engine and torque of any light duty pickup truck engine.

The 6.2L V-8 available for Silverado LTZ and High Country and Sierra SLT and Denali models also delivers class-leading maximum available trailering capacity of 12,000 pounds when properly equipped.

Along with power, now comes strong fuel economy as EPA estimates for the 6.2L V-8 EcoTec3 engine technology enable 2WD Sierra and Silverado models to achieve 15 mpg city and 14 mpg city for 4WD. EPA highway estimates are 21 mpg for 2WD versions, and 20 mpg for 4WD models.

“Power and towing capacity are fundamental capabilities for full-size pickups,” said Jeff Luke, General Motors Executive Chief Engineer for full- and mid-size trucks. “The 2014 Silverado and Sierra deliver unmatched power and towing capability with a host of ingenious driver aids.”

The optional Max Trailering Package is available on 2WD and 4WD V-8 crew cab and double cab models and includes:

§ Trailering package with seven-pin and four-pin connector

§ Enhanced cooling

§ Automatic locking rear differential

§ Heavy-duty 9.75-inch rear axle with 3.73 ratio

§ Increased-capacity rear leaf springs

§ Revised shock tuning for increased control

§ Integrated trailer brake controller.

In addition to the 6.2L V8, Silverado 1500 and Sierra 1500 will offer a 4.3L V-6 SAE-certified at 285 horsepower and 305 lb-ft of torque and a 5.3L V-8 certified at 355 horsepower and 383 lb-ft of torque.

Silverado and Sierra trucks equipped with the 4.3L V-6 will have available towing ratings of up to 7,600 pounds, the highest for any base V-6 in the segment. Silverado and Sierra trucks equipped with the 5.3L V-8 and the max towing package, available later this year, will have towing ratings of up to 11,500 pounds when properly equipped.

All three engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitor vehicles. The engines also use a compact overhead-valve design and weight-saving components such as aluminum blocks and cylinder heads to reduce mass for additional energy savings.

All three provide the proven power, torque and dependability of a large-displacement engine, seamlessly switching to four-cylinder mode to save fuel during light-load driving. The 5.3L V-8 has EPA-estimated fuel economy of up to 23 mpg highway (2WD models), the best of any V-8 pickup, and better than Ford EcoBoost V-6. .

14 mpg in the city?! Unacceptable, I'm buying a ford!!

 

I want the max trailer package simply to get the increased cooling and the 3.73 rear end for uh...hooning purposes but it doesn't look like you can equip it on a truck with the all terrain package due to the suspension conflict. Damn.

 

Colour matching trim or more burnouts.....

I'm thinking the better mpg numbers are for the 3.42. Still great though. If 3.73 then even better. Still getting one. Yeah!

The 6.2l is suggested premium gas correct? Was avg. 14.5 in my 08 denali. So this engine should be a few mpg better.

 

Correct. I average 14.5 with mine which is better than I expected. I bet the new NHT will get better than that, especially when they go to the 8spd transmission.

Zane,are EPA numbers based on the 3:42 axle ratio,or did EPA test a MaxTrailer,3:73.Nice fuel numbers for the EcoTec3 6.2L.Also Dan-Man you better look at EPA's website for the Ford F150 6.2L has a EPA rating of 12 city and 16 highway 13 combined.Ouch.

Not entirely sure but my guess is whatever rear-end comes standard. Most likely the 3.42. Then they are using the 3.73 for the max trailering numbers. Keep in mind, the trailering/hauling figures are not J2807 certified.

"SAE-certified 420 horsepower (at 5600 rpm) and 460 lb-ft of torque (at 4100 rpm)" So what's the red line? Also power numbers in lower rpm would be nice to see, probably reached eventually but still curious.

Zane,my guess too,until a more through testing of Chevrolet High Country 6.2L,with a 3:73,MaxTrailer package by one of the automotive news journalist possibly (Fast Lane).I thinking a rumble in the rockies with these 1/2 tons should do the trick, GM 6.2L High Country,3:73, verus F150 6.2L Platnuim,3:73 verus Rams Laramine 5.7L 3:98,8 speed. All towing 10,000 lbs ball hitch,sway bars hook up as well.As far as J2807 specs trailer/bed is along way off.Ford declined the offer of Toyota,GM to go to J2807 trailer/bed specs loads.I imagine all 3 there will go there after Ford's redesign.Ford,GM,Ram all have axle ratios very close in the 3:73,Rams is a little higher at 3:92 I believe.Ford offers a 3;73 and a 4;10.So this could be a very close contest to test the engineering levels.Ram Sport does offer a puller at 10,000 lbs as well.

Just a heads up Fast Lane ran a 0-60 with a 6.2L (L86),IN A 3:42 ratio truck in Austin,Tx were (Zane was as well),he ran a 7:61 secs.Imagine what a 3:73 will run.Stab-Trac was turn off.Video is up on FastLane,its is the second video provided.

Thanks for the update Zane. Do you have any idea on what the actual increased spring capacities are? I have read the NHT adds 150 lbs of weight in CC trim. Still no reports on actual payload increases to match the towing increase?

Well the "fast lane" drivers should stick to the slow lane then. C&D tested a 5.3 3.08 equipped CC @ 7.7 0-60...sooo, that time is horrific for a 6.2 w/ 3.42's

I'd like to get one of these too, but the Ram EcoDiesel has caught my attention with the recent reviews. If a programmer comes out for this engine it could be fantastic with the mileage and the power.

 

Maybe if Dodge has success with this model it'll finally get GM off their arse and force them to put a diesel in the 1500's.

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
