      This Silverado was only towing 7600 lbs but the Ecodiesel towed 8700 lbs. Is that a fair comparison? How is this Silverado even eligible for the contest when it's towing over 1,000 lbs less than the the other trucks?

    • @16vjohnny
      @16vjohnny 2 роки тому

      Not just cruise. You have to use the brake pedal. The software is trying to make you not have to think about it and so you have to use the brake pedal. I can get mine to downshift and you can feel the exhaust brake kick in.
      The way TFL does their test (60 to 50), won't always activate it. But once it's active, it will keep the RPMs high until you touch the accelerator pedal again. I think it probably works for most people (grocery getters + towing on the weekend) but I would really prefer to have more control over it like they offer on the HDs.

In my opinion the on board telemetry should adjust when it senses extreme elevation decends & climbs. A Performance chip could help with the climb, but not downhill braking.

    • @hogrod

      @Zesty Meatballs The max tow package comes with lower axle ratio. The 2wd currently has 3.23 ratio but the 4x4 3.0L diesel has 3.42 and can already tow 2000lbs more than this truck they tested.
      Max tow also has larger coolers which I'm sure the dodge already is utilizing to get a higher tow rating.
      Power wise the dodge has 260hp@3600rpm and peak torque 480lb-ft@1600rpm dropping off from that point. It's also backed with an 8 speed auto.
      The 3L duramax has 277hp@3750rpm and 460lb-ft from 1500-3000RPM with 95% of that available at a low 1250rpm. Backed by a 10 speed auto.

    • @hogrod
      @hogrod 5 років тому +1

      closer ratios certainly do effect towing, less rpm change between gears keeps the engine more in its sweet spot.
      still haven't addressed any reason the dodge can tow more than the Chevy with dodges less useable power? Just a claim chevys somehow engineered for mpg, even though it clearly makes its torque over a much broader rpm range. Only thing possible that's different is cooling.

    • @hugelandmonster
      @hugelandmonster 5 років тому +4

      Reason why it tows much less is because of too much heat. The reason was to chase MPG over max tow. They chose to alter emissions exhaust architecture to achieve this!
      Emissions equipment was packaged very small and close to the exhaust manifold. This allows exhaust to run hotter than conveniental designs, specifically reducing the need for post fuel injection which slips fuel pass the compression stroke to burn off soot build up in the DPF for a hotter exhaust will reduces soot build up, thus mpg improvent can be made since fuel wasting is reduced over standard emissions intact configuration.
      Duramax EGT's can't go over 1560F before it de-rates via de-dueling to protect the engine from too much heat. High temps can literally melt pistons.
      If they stick with their exhaust emissions design they will have to drastically cool intake temps much greater than normal to tow the same weight. I'm not sure if larger intercooler can do it alone... Most address high EGT's with deleting which they can't do, or pairing higher capacity intercooler, compound turbos, and high flow intake elbows. These approaches drop EGT's by ~300F.
      Making max power for a Dyno certificate is not the same as sustainable max towing power with acceptable heat tolerance. This is the same issue with Dyno/Dragstrip bragging rights vs real world work!

      I can tell you exactly why it was such a poor showing. I have a 3500 Duramax and the exhaust brake will not engage unless two criteria are met. 1.) The brakes are pressed. 2.) The cruise is set. If they would set the cruise at 50mph, the truck will try to maintain that speed by downshifting and exhaust brake engagement. Simply trying to coast down the hill will not engage the grade holding algorithms.

    Hey Kent and Andre I figured it out guys.

So you would have had way fewer brake applications knowing that ahead of time.

My ‘04 Dmax with Allison down shifts aggressively with one or two brake applications, sometimes just touching the brakes with no actual brake action. One or two gears depending on where it started. Actually downshifts shifts past redline when needed, near 3800 rpm.
      So the trans didn’t look like it downshifted at all. Steep angle down and brake applications should command a control shift. Some issue with the TCM parameters is to blame.

Due to gravity, the truck then accelerates and you repeat the process. Please explain to me how the truck is supposed to know what the hell you want it to do? It can't read minds yet by your comments, you expect it to downshift and apply the exhaust brake. And even if it did, how much should it downshift and how much exhaust brake should it apply? To maintain what speed? How about telling it you want to maintain 50 mph (it's called cruise control!) and then see what it does.

    We really appreciate the review gentlemen. The truck looks nice, sounds good and appears to run well.
    Quick question though, is the rear axle gearing better for towing in the 4x4?

    What ever happened to the 4.5L Duramax? Didn't they have that as a concept in the 00's?

      It was mothballed during the GM restructuring. It was also designed back when emissions requirements were less stringent than this design.

      2020 CHEVROLET SILVERADO’S NEW, ADVANCED 3.0L DURAMAX TURBO-DIESEL REDEFINES EXPECTATIONS
      No-compromise engine delivers refinement, performance and efficiency
      2019-06-03

      DETROIT - The all-new 2020 Chevrolet Silverado’s available 3.0L Duramax inline-six turbo-diesel engine adds choice and versatility for full-size truck customers, offering class-leading torque and horsepower in addition to focusing on fuel economy and capability. It is the first-ever inline-six turbo-diesel offered in Chevrolet’s full-size light-duty trucks.
      Chevrolet engineers started with a clean-sheet design and developed an all-new engine that leverages the efficiency and refinement advantages of the inline six-cylinder architecture and incorporates advanced combustion and emissions technologies to optimize performance and efficiency. It is priced identically to the 6.2L V-8 as a $2,495 premium over a 5.3L V-8 model or $3,890 over a 2.7L Turbo model.
      “From the moment the engine is started, to its idle, acceleration and highway cruising, the 3.0L Duramax performance will change perceptions of what a diesel engine can offer in refinement,” said Nicola Menarini, director for Diesel Truck Engine Program Execution. “With advanced technologies that draw on global diesel expertise, it’s a no-compromise choice for those who want the capability and driving range of a diesel in a light-duty truck.”
      Available on LT, RST, LTZ and High Country models, the 3.0L Duramax diesel rounds out the new Silverado’s range of six propulsion choices, each tailored to suit customers’ needs for performance, efficiency, technology and value. It is rated at an SAE-certified 277 horsepower and 460 lb-ft of torque delivering 95 percent of peak torque at just 1,250 rpm. Peak torque is sustained from 1,500 rpm through 3,000 rpm, providing a powerfully smooth and satisfying driving experience.
      The 3.0L Duramax is paired with GM’s 10L80 10-speed automatic transmission, featuring a centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness, reinforcing its performance, efficiency and refinement. This combination also offers exhaust braking, which uses the diesel engine’s compression to help slow the vehicle, requiring fewer brake applications by the driver when in Tow Haul mode.
      Innovative Engine Technologies
      The inline six-cylinder architecture offers inherent efficiency and refinement, but the team expanded with smart technology choices to help improve efficiency and weight while optimizing the truck experience. A lightweight aluminum block and cylinder head reduce overall mass, and Active Thermal Management enhances efficiency and cold-weather warm-up. Ceramic glow plugs also help with shorter heat-up times and a quicker cold start, meaning the engine block heater is not needed until -22 degrees F.
      Towing is an important part of owning a truck, and customers can gain additional confidence thanks to the exhaust brake available in tow-haul mode. The water charge air cooler, coupled with low pressure EGR, reduces time to torque. The variable geometry turbocharger helps provide a greater balance of performance and efficiency, and an electronically variable intake manifold helps optimize performance across the rpm band.
      Inherently efficient and balanced
      Compared to a DOHC V-6, the inline-six architecture offers greater efficiency from the reduced friction of operating only two camshafts and their associated valvetrain components. The I6 configuration offers the perfect balance of primary and secondary forces, without the need for balancing shafts.
      “In addition to reduced friction, the architecture enables smooth operation,” Menarini said. “The new Duramax 3.0L elevates the 2019 Silverado with one of the most refined and efficient diesel engines in the segment.”
      Along with supporting elements such as a tuned air induction system and other noise-attenuating elements, the 3.0L Duramax delivers exceptional quietness and smoothness at all engine speeds.
      All-aluminum construction and tough rotating assembly
      The 3.0L Duramax cylinder block is made of a cast aluminum alloy that provides the strength required to support the high combustion pressures that occur within a diesel engine, while also offering an approximately 25 percent mass savings over a comparable cast iron engine block. Iron cylinder liners are used within the aluminum block to insure truck durability.
      There are seven nodular iron main bearing caps that help ensure the block’s strength under those high combustion pressures, while also enabling accurate location of the rotating assembly. A deep-skirt block design, where the block casting extends below the crankshaft centerline, also contributes to the engine’s stiffness and refinement. It’s complemented by a stiffness-enhancing aluminum lower crankcase extension attached to the main bearing caps.
      The rotating assembly consists of a forged steel crankshaft, forged steel connecting rods and hypereutectic aluminum pistons. The alloys in the respective castings for the rods and pistons make them lightweight and durable. Silicon is blended with the aluminum for heat resistance and tolerance within the piston cylinders, which enhances performance and makes the engine quiet.
      A thick piston crown - the top of the piston - and reinforced top ring add strength to support the tremendous cylinder pressures enabled by turbocharging and the engine’s high 15.0:1 compression ratio.
      DOHC Cylinder Head and Rear Cam Drive
      Overhead camshafts offer a direct, efficient means of operating the valves, while four valves per cylinder activated by maintenance-free finger followers with hydraulic lash adjusters increase airflow in and out of the engine. This arrangement is integrated on the Duramax 3.0L’s lightweight aluminum cylinder head, which is topped with a lightweight composite cam cover that incorporates the crankcase ventilation and oil separation systems.
      A pair of lightweight, assembled camshafts actuates 28.35 mm diameter (1.12-inch) intake and 24.55 mm diameter (0.97-inch) exhaust valves. The camshaft drivetrain is uniquely located at the rear (flywheel side) of the engine, for greater refinement and packaging considerations for the comparatively long inline-six. A crankshaft-driven chain drives the high-pressure direct-injection fuel pump, while a chain driven by the fuel pump drives both intake and exhaust camshafts. A smaller belt drives the variable flow oil pump from the crankshaft.

    Yup. That 10spd needs better tuning. GM relied too much on the exhaust brake to do the work, which how the tuning is now it will save the trans more (less heat) and a smoother ride.

    So comparing this to the 3.0 Ecodiesel, the Ecodiesel is quieter, has better downhill brake control, slightly slower (38s) up the Gauntlet and 1MPG over 66 miles heavier. Which one is better? I think the 8 speed and towing setup is better on the Ecodiesel but it's very close and both blow the Ford out the water.

    Were you in snow/ice mode? Because it may be a safety feature that reduces rpm and possibly shuts off the exhaust brake to avoid slipping on ice?

      Fuel economy would be the biggest factor I would think. Good to have options. I love the 6.2 10 spd combo in my Sierra AT4 and wouldn’t want the diesel but that’s just me. I’m still glad they’re are offering the diesel.
