    GM Inline-6 Diesel Rated

      .... GM takes the light-duty diesel power crown.

    The GMC Build and Price tool has let the details slip on the power ratings of the upcoming inline-6 diesel due to be released in the Sierra and Silverado in a few weeks.  The 3.0 liter turbo diesel will produce 277 hp at 3,750 rpm and 460 lb-ft at a mere 1,500 rpm. The only transmission choice will be the 10-speed automatic. These numbers are SAE certified and verified by GM. The diesel motor will be available on LT and above trims on the Chevy and on all GMC trims except the base.

    These numbers make the GM six more powerful than Ford's V6 Powerstroke diesel which runs at 250 hp and 440 lb-ft of torque.  The New Ram 1500 still hasn't gotten a diesel unit, but it will probably be the same rating as the 260 hp and 442 lb-ft of torque in the Jeep Gladiator.

    One area still unknown on the GM unit is fuel economy. The Ford F-150 Powerstroke is EPA estimated for 30 mpg highway/25 combined/22 city. 

    The GM diesels 1500 trucks will be at dealerships this summer.

    The price being the same as the 6.2 is HUGE. i think that lone will help get sales moving on this. The premium Ford and Ram charge is outrageous.

    I priced the cheapest F150 with their 3.0 and it's 47k. The cheapest 4WD + Super Crew cab is 53k. Insane.

    If GM can build a great I6 diesel, then why can't (or won't) GM build a great gas I6?  Cadillac/Camaro/Corvette(?) could use one.

    They should make an I-6 gas in a final death blow to the 3.6 V6.  Anything front drive can get enough power from a 4-cylinder especially with electric boost as an option.  So if 6 cylinder is only in rear drive then it should be inline. 

    Side note, they should put the in-line 6 in the Tahoe also.

    Why confused @balthazar.

    7 main bearings > 4 main bearings, plus less vibration from imbalance = better longevity everything else being equal.

    The increased number of bearings are necessary due to increased crankshaft length/ torsional stresses.
    V6 doesn't have room for more than 4, but doesn't need more either.

    I'm not sure an empirical study has been made studying your claim, would be interesting. Probably too many factors to isolate one cause (oiling, engine speed, start/stop cycles, etc).

    BTW- there have been 4 main bearing I6s in the past, wonder how they stack up to a V6 for longevity (4 = 4).

    I had that same 300 in my '94 F-150 - tough beast. But part & parcel of that longevity is the fact that motor was like what- 25 years old? All the bugs were long ago worked out of it, and the era it was gestated in was on the tail end of over-building motors.

    Still... even in BMW and Benz and even the Atlas I6... the motors long outlasted the vehicles they were in.

    Yeah- some indeed did. The MoPar 225 was one of the 'unkillable' I6s, but it came out in 1961.
    The old, decidedly unstressed Stovebolt 6 from Chevy was another- lasted forever, built for decades.
    But the Pontiac I6 was no longer lasting than their V8 (another very long-lasting 'plant).

    I'm not convinced cylinder arrangement is the leading cause of longevity- too many other factors.
    I have no data to contribute RE foreign I6s in this arena, tho.

    • So the Lightning was too expensive and the solution is to add an ICE motor and more complexity on top of that.  Can't wait to see the $99,995  F-150 XLT EREV.
    • I did that quiz that told me what state was most suited to my personality.  I did it 2 times a few weeks apart and I kept saying Texas.  How does relaxing, drinking hot tea, not liking crowds, and liking the mountains line up with Texas? So I just did another one that would be able to see what region I'm from.  This one is a hoot.  I am from diagonally across the country from the region indicated and I spent 21 of my first 25 years there.  Now, every place I've been for work or school, or even if just a party, the Northeast is inevitably where the people that I reel in come from ... like a freaking magnet.  It never fails. Happy Christmas Eve.
    • Yeah...it is a beautiful road for what I could tell from the videos I see.  Like you @Robert Hall from seeing all kinds of video media of it.  I do admire the fact that you actually drove on it.  Plus all of your travels of your country that you did and continue to do.   @A Horse With No Name and @trinacriabob also have that respect from me for the same reasons. Matt Farah does plenty of car reviews on this road. At least I think its part of this road. Or when Jay Leno references to get out of Los Angeles and head to the mountains where there are no people he says.  In a different time, I would have loved to visit California.  I was California dreamin' during my teen years and always loved the sights and dreams of California.  Then in my 30s or 40s, I wasnt into California as much.  Then JUST before trump became president for the 2nd time, I was falling in love with California again (minus that hollywood creepiness) only to be happy to shyte on ALL of the usa including california. I know I have become a douchebag these past few months regarding your country, but the political climate of your country has made me bitter and hateful.  I know I shouldnt be lumping ALL of the crap that is maga and trumpism into one huge bowl of hate for all things american, but it is what it is... There are many parts of the usa that I NEED to see before I die.  California is one of these parts that I NEED to experience.  And for all the maga deplorable bullshyte that is florida, the Keys are another part I NEED to see.  Video gaming talent being lost due to excessive speeds (on roads that seem to be heavenly to auto enthusiasts) is sad indeed.   For the human element of someone dying...  There will be others to take his place.  What is sadder is that he could actually afford "track days" on SEVERAL California race tracks.  He could have asked Ferrari (paid an additional  small fee) to have Ferrari, the OEM, to tune his Ferrari with THEIR engineers and race crew to the optimal race track settings of ANY race track IN THE WORLD and he could have raced his SF 90 to the car's fullest capabilities without the risks of killing innocent peoples on public streets. And if he chose an additional option on his Ferrari purchase, Ferrari race crews could have also taught him to reach his  fullest capacity of his talents. And he could have afforded all those things too.   What I find extremely frustrating is that he has money to feel like a superstar with his $800 000 Ferrari racing his car in all kinds of exotic locations having a personal Ferrari pit crew cheering him on, and if he chose, to have high priced escorts in scantily clad clothing as cheerleaders but no...he chose to have street take-over/cars and coffee hoodlums cheer on his and hid friend's demise. While a couple of them stood their in disbelief and yelled "oh shyte" and "oh phoque"  and dragged his friend's body like it was diseased away from the burning wreck, most of them fled the scene like cockroaches they were.  I guess this was the way he valued his life.  Driving fast in the lowest common denominator kind of way and dying in that same low common denominator way. THIS is what is frustrating to me, he had the money that he worked hard for to enjoy the prestige of owning and racing a Ferrari...  Instead, he put innocent people at risk for cheap thrills.   I understand why poorer people drive fast, especially on intoxicating roads like Angeles Crest, because I understand the adrenaline rushes that come from that environment.  I do not condone it, I understand it. But he, he had the money to die a more dignified death with the same adrenaline rush. But THAT also wouldnt involve in risking any innocent peoples lives either.  At least with me, if I ever remember his death in the future sometime, I will remember him as the clown who drove too fast and killed his friend.
    • Yeah...my impression was that in the past in the UK they were an old money type of car.  They were conservatively styled, quietly luxurious..now just another gauche bling toy for vapid overhyped people. 
    • This is one of the great stupid things about people that are book smart, common sense stupid in that they think because they can afford to buy expensive exotic sport cars they can drive them crazy fast everywhere and the car will handle the turn, sadly one cannot deny gravity and physics. They get what they deserve when thinking they are better than others cause they can afford the exotic auto. Sad that humanity lost his skill in game making.
