General Motors reported this morning that the all-new Silverado equipped with the 3.0-Liter Duramax diesel engine has earned an EPA-estimated 33 MPG Highway in 2WD configurations. Here is a quick look at the numbers we have so far:
2WD Silverado Duramax = 33 MPG Highway, 23 City
4X4 Silverado Duramax = 29 MPG Highway, 21 City
Here are a couple of quick comparisons:
2019 Ford F-150 2WD Diesel = 30 Highway, 22 City
2019 Ford F-150 4WD Diesel = 28 Highway, 22 City
2019 Ram 1500 2WD Diesel = 27 Highway, 20 City
2019 Ram 1500 4WD Diesel = 27 Highway, 19 City
**2020 Chevrolet Colorado 2WD DIesel = 30 Highway, 20 City
**2020 Chevrolet Colorado 4WD DIesel = 28 Highway, 19 City
“We designed the all-new Silverado and the all-new 3.0L Duramax turbo-diesel to deliver both performance and efficiency,” said Tim Herrick, Silverado executive chief engineer. “The engine utilizes state-of-the-art technologies to optimize every drop of fuel, and takes advantage of architectural changes to make Silverado larger, lighter and more aerodynamic than before. The resulting combination offers all of the performance, refinement and capability customers want in a full-size truck, with highway fuel efficiency you would expect from a family sedan.”
The trade-off for fuel economy alone will worth calculating. In addition to the higher fuel cost compared to gasoline, for the LTZ and High Country, the 3.0L Diesel is a $2,495 option (identical to that of the 6.2L V-8). For the LT and RST, it is a $3,890 increase over a 2.7L Turbo engine. For those looking for diesel towing capability, the choice will be an easy one.
The EPA has not yet published full MPG and emissions information on the new Duramax at its site, www.fueleconomy.gov. Once data is posted we will do a more in-depth post on the comparison to some other Silverado models. First deliveries of the 2020 Silverado with the Duramax engine will be this coming fall.
Installed the borla type-s exhaust couple days ago.
build quality is excellent, fitment was absolutely spot on.
took me 5 beers and about 2 hours...
my thoughts.. on the system... also have a type S on my SRT...
1. Cold start is aggressive! It literally barks.... I was very surprised by this, much louder than my SRT system...
2. After engine warms up and rpms settle down it has the very standard s-type deep burble at idle. If the truck is parked and just running, walking behind it is just music to my ears. Very deep little burble that just sounds great.
3. As you ramp up the rpms and roll through the gears, the sound is deep and pronounced, this is the loudest type-s exhaust I’ve heard. Not in a bad way, just know that you will hear this exhaust unless you absolutely butter the throttle and accelerate like an old woman.
4. No drone in 9th or 10th gear.. no goofy noises or vibrations with cylinder deactivation stuff so that’s a major plus.
happy with the purchase, louder than expected but still nothing too crazy. Getting the ATAK version would be overboard for a pickup in my opinion...
engineers at borla said their touring style is identical to the gmc branded perf exhaust in regards to sound output.
so their 3 levels are
type-s - pretty big jump, aggressive! Crazy cold start that barks
atak- crazy man over the top sound, I don’t think many guys would go this extreme
will get better videos soon
While I was admiring the underside of my bran new 19 Silverado I noticed the exhaust pipe, immediately after the cat, is squished, like super flat... Has anyone replaced that section with a normal round piece of tubing? Did it make any improvements in sound/mpg? Seems like it must!
Hey peeps, I have a 15 GMC sierra 1500, it has the max tow package, with a 5.3, 6l80e, and 3.73 gears. What kind of fuel mileage are people getting with the same set up. I have some buddies that have similar rides, both 15 GMC's one has 3.08 gears a 5.3 with a speed and the other is 6.2 and an 8 speed with 3.42 they both get over 24 mpg. Anyone out there getting 19-20 on the highway like mine?
Now that I am a bit older with a family, the days of extreme loud exhaust in sport cars / trucks has come to somewhat of an end. I have a 2016 GMC Sierra 1500 with the 5.3l. About a year ago I decided to try out the Magnaflow cat back 3" and had a horrible drone through pretty much the entire RPM range. I tried everything to calm the drone but nothing seemed to work. I tried a couple of Borla exhaust systems and still too loud of a drone. I wanted to share a new cat back exhaust I just had installed that I am more than pleased with. The exhaust is handcrafted by MRT Performance in Plymouth Michigan, near where I live. They use T304 piping and they spent a lot of time developing and perfecting a bad a$$ muffler with a drone rating of 1 out of a 10 scale. Meaning 1 is almost no drone. The exhaust tip comes welded on and nice exhaust clamps are included. A buddy recommended them to me after my numerous failed attempts of finding a low drone, performance exhaust. I wanted to share this because I have read other posts about guys wanting performance exhaust but without the loudness / extreme drone. I have to tell you that I am so impressed and so relieved the drone, that was giving me headaches, is now gone! The low nice sounding rumble is there that at cruising speeds, and going WOT gives me that ear to ear grin! Normally I would not post about products I buy, but I had to share this newest purchase. The nice thing is I can have normal conversations at all RPM levels. The cool thing is MRT posted two nice videos of interior and exterior sounds using their Silverado test vehicle. I purchased the MRT Deep & Mellow cat back. They do ship their systems too. I attached some photos of my truck with the completed system in place.
