BMWs new quad-turbocharged diesel

Details on new BMW diesel

Looks like BMW is making some serious power out of their new 3.0 inline 6 diesel. This little oil burner is making 394 HP and 560 lbs of torque. I'd like to know the reliability of these four turbos.

That's cooool. You'd be the only d bag to show up at the country club with quad turbos. Good part is, that's so ridiculous that you'll be safe for a while. No one will try to one up em with 5 turbos!

A BMW is costly to maintain as it is. I would not want something like that to maintain!

No thanks!

My response is.... why...why would a manufacturer makes something so complex ?

I would think the most reliable and durable diesel engines out there...on the road.. are in highway tractors.

I'm no expert, but I believe they are generally inline 6 cylinders, of around 10-16 liters and have one turbo.

I don't know how complex they are, I would think an engineering design goal would be to keep a highway tractor engine as simple as possible...to ensure reliability/durability.

Are 4 turbos necessary for consumer engine such as this BMW ?

You know you are right. They should have stopped building engines when the model T came out. Why the hell are they trying to make things better. IDIOTS!

I see. Thank you for your contribution.

The average price of a 7 series is north of a 100K so this engine probably won't break any of its buyer's wallets.

BMW = Break My Wallet

this engine look ridiculous

Actually, he has an interesting point. All of the big three diesel pickups have one turbo although I think the one on the 6.7 Powerstroke is a dual-stage. I'm guessing that BMW is using that many for quick boost response and also to be able to fit more combined turbo capacity under the hood.

And, my two-cylinder Maxwell gets down the road just fine. Why the heck does one need to upgrade to a Ford Model T with four? Just that much more to go wrong . . . .

BMW is already making some of the world's fastest diesels: http://www.cheatsheet.com/automobiles/alternate-fuel-wonders-the-20-fastest-diesel-powered-vehicles....

Maybe we'll get to hear some higher spinning diesels in the future:

First off, this engine application looks like its for their flagship 7 series which mean the customer already has a lot of money. I'm sure there's a performance edge to this that BMW is pursuing. I for one would stay away but I do like BMW pushing the boundaries. This application may offer useful data for future diesel applications.

I think they're building on the theme of one turbo to feed a second turbo to cut down on turbo lag time? And then due to today's small engine compartments they probably have gone to two turbos on one side of the engine and two on the other side to cut down on the large turbo piping.

More components means more likelyhood of a failure. I wonder if the turbos are different in sizes and what ranges where they work. I could see a scenario where they are somewhat cascaded. I have seen combos of supercharger and turbocharger. The power of a supercharger starts immediately but the turbo takes over at higher RPM.

Bigger question: Where are they hiding?

[bguy]

Could easily get away with 2 turbos. One smaller for response and a larger on for power.
