Listen To The Cadillac Escalade Diesel Start Up And Rev: Video

Although the all-new 2021 Cadillac Escalade went on sale nearly a year ago, production of the Escalade diesel variant (badged as the 600D) at the GM Arlington plant in Texas began only a few weeks ago.

Now that the Cadillac Escalade diesel actually exists, we though it was time to get some seat time in the model, as we did in this video. We hear the engine start up and immediately settle down to a smooth idle. The small amount of noise it produces is almost inaudible against the sonic background, until our camera operative comes within a few inches of the exhaust tailpipes.

At higher revs, the sound naturally becomes more obvious. However, the typical diesel clatter is less evident than the tone of the inline-six motor.

The Escalade diesel’s engine is GM’s 3.0L I6 LM2 turbodiesel motor from the ‘baby Duramax‘ family. It produces 277 horsepower and 460 pound-feet of torque, and drives either the rear wheels or all four through the GM Hydra-Matic 10L80 10-speed automatic transmission. The torque figure is identical to that of the Escalade’s standard 6.2L V8 L87 gasoline unit, which makes 420 horsepower. 460 pound-feet is equal to 623 Newton meters, and GM has rounded this down to 600 Nm to give the V8 and diesel models designations of 600 and 600D, respectively, under Cadillac‘s current naming convention.

Unsurprisingly, the Escalade diesel is much more economical than the V8. The rear-wheel-drive Escalade diesel is EPA rated at 21 mpg in the city, 27 mpg on the highway and 23 mpg combined. The equivalent figures for the rear-wheel-drive V8 gasoline are 15 mpg, 20 mpg and 17 mpg. The changes should be appreciated by some, despite the large luxury SUV being the complete opposite of a frugal purchase.

The diesel engine is officially a no-cost optional alternative to the V8. It is offered with every trim level in both the Cadillac Escalade and long-wheelbase Cadillac Escalade ESV full-size luxury SUV ranges, at least in North America. GM has confirmed that the Escalade diesel will not be sold in Japan or the Middle East, and it is unlikely to be exported to Australia, where diesel sales make up a small – and diminishing – proportion of the market.

After all that, do settle back and enjoy the subdued sound of a Cadillac Escalade diesel here:

  • I see a limited audience for the diesel,who drops 100k and worries about saving a buck at the pump,depreciation is probably going to be high, this engine is not real world tested and diesel maintenance and repairs will cost you more.

    • I have a Yukon with the diesel. I drive 50,000 miles per year. It's not so much that I'm worried about saving money at the pumps, although with my mileage it's pretty significant. But its the fact that I can get 250-300 more miles per tank without having to stop. Real world numbers: I've gotten my rolling average as high as 35 mpg. The 3.0 is the best motor option for these trucks, in my opinion.

    • Trying to purchase a diesel Escalade right now is impossible because they are in such high demand, just sayin.

    • You’ll care about saving a buck at the pump when your taxes go up.
      Let the wallets of the financially foolish bleed in agony.

    • Ah......according to budlar: "depreciation is probably going to be high".

      Maybe you should check out the prices on used trucks with the diesel. Because there are very few large SUV's with diesels, it's difficult to get an accurate value for a used one. But even an older Ford Excursion with a ton of miles and the diesel will bring huge money. That's not including the luxury market. So I think you may have mis-spoken.

      • They are covered under a 100,000 miles warranty unlike the 60k gasoline engine warranty.
        Your Ignorance is noted.

      • Melania, why are nearly all of your comments either irrelevant, negative, or ignorant to the facts? ...asking for a friend.

      • Yes because we love dropping 100k only to see it sitting in the dealers garage waiting on parts. That was my experience with this engine. Sure it was fixed on their dime and i got to drive around in some tiny crappy Buick suv loaner. Parts take weeks to get and i had multiple issues per year.

        • Ah, are you the same dude who lives in Alaska and have been doing nothing but bawling about it on the Facebook group?

  • Personally I love diesels. Grew up on a farm, so it kind of comes naturally. What I'd love to see is large SUV and trucks offer a diesel hybrid to get the best of both worlds. IMO, the larger truck/SUV market is where we really need the tech to most increase MPG's rather than always putting it on the smaller cars that already get better MPG's. Imagine the amount of fuel this country could save by having the larger trucks/SUV's getting 35 + MPG with a diesel hybrid instead of even 23 + for just this diesel let alone the under 20 they currently get.

  • Quieter than a gas engine. They are amazingly quiet and run very well. A friend towed a large Ranger bass boat, around 4,200 lbs, on a tandem trailer with his Silverado 1500 and got 25 mpg.

  • I like the last part of the video when they were revving the engine. The first part of the video was just crap. All I heard was people talking in the back ground. I almost stopped watching because it was so boring. But once they started revving it up that got my attention.

  • Come on you know what these cost new and their value 2-3 years later! Its not hard to calculate and its ugly. While the residual value of escalade is far better than their car linup its still much higher than its cheaper Yukon sister. Other big problem is selling a $50k+ used vehicle yourself is very difficult and most eat another 10%+ loss trading it in.
