BMW's i-6 diesel turns into a V-8 fighter

By Jens Meiners, BIMMERPOST Correspondent

Even though it has somewhat fallen out of favor on the US market, the diesel engine remains immensely popular in Europe - especially on executive sedans. In the interest of efficiency, BMW (and Mercedes-Benz) dropped out of the business of building V-8 diesels a few years ago - but Audi remained commited to the V-8. BMW's response was the tri-turbo straight-six, offered in the 5- and 7-series and the X5. Now that tri-turbo is being retired. But it makes room for something more awesome: A new i-6 diesel with no less than four turbochargers.

At the Vienna engine symposium today, BMW confirmed its new, top-of-the-line oil burner. The new, top-of-the-line 3.0-liter i-6 will be fitted in the 750d xDrive; other model lines will follow. It will make 394 horsepower from 4000 to 4400 rpm; maximum torque is rated at 561 lb-ft, available from 2000 to 3000 rpm. On the road and fitted in the 7-series, it translates into a 0-60 mph time of around 4.5 seconds; top speed will be governed at 155 mph.

The objectives were clear: More power, better response, high-revving capability, and creating a convincing "V8 fighter." Based on BMW's new modular engine layout, it is testament of that architecture's capabilities. The spectacular design features four exhaust turbochargers - two high-pressure chargers and two low-pressure ones. In terms of turbocharging, the main change was replacing the massive low-pressure turbocharger with two smaller common exhaust turbochargers; they came at a cost advantage and without a weight penalty.

While the engine delivers immediate response and incredible high-end power, fuel consumption has been reduced by around 5 per cent. Maximum torque, by the way, is limited by the capabiliies of the XF 8HP 8-speed automatic. The engine, by itself, could deliver more. No wonder the diesel is so popular in Europe; we applaud BMW's move to raise the bar once more.

Oh my goodness! All of the turbos. I can't wait to have a go with this thing... I'm going to pull down a skyscraper with the torque.

Nice! Gotta love a diesel.

Coming to the US market?

The future is now!

[sward]

Will it be fitted in X5 M50D?

[joz]

I wish North America had better diesel options. All that torque!

[Testercles]

Let's hope this one comes to Australia in something other than the X5 50d

[UltimateManga]

This engine looks like a monster and so much fun with all that torque can't wait to get my hands on a model with this engine bring it on!

[Mdecisive]

Hey man.. I heard you like turbos ..

[Blubaron79]

I want this in a 3 series right MEOW!

This will replace all models currently fitted with the 50d engine!

The only concern I have with thid is the increased complexity in the system. More turbos, more pumps, hoses more things to go wrong. When it does break the bill will be a lot higher than usual.

Still, it's great to see this kind of engineering.

[Taunto]

if this comes to NA..it's going to be a nightmare replacing turbos due to oil consumption....

[mkoesel]

I guess this is a called the B57S then? Or did they change the naming scheme up?

Either way, it sounds great on paper. I wondered how soon they'd come up with something to answer Audi's new 4.0L V8 diesel in the SQ7. Though this makes 10% less power, it is impressive that they are now over 130hp/L. And the I6 should be more efficient, though we'll see once an X5 50d is compared to the SQ7

No way.

BMW's engineering prowess never ceases to amaze me but their turbo applications aren't exactly the most reliable. Would be afraid to see what would happen when something mechanical happens with or without the turbos failing. Yikes.

Don't be so quick to desire the diesels. While they are cleaner than ever before, they still lag behind the gasoline counterparts especially when it comes to certain very harmful nitrogen oxides by-products.

It has led to at least one country in Europe to ponder a move away from diesels, after studies have shown there could be a correlation between widespread diesel adoption and increases in certain forms of cancer. France was the country with some of the highest percentage of diesel market share, and for years they have incentivized diesel cars - that may change drastically in the near future.


Stay tuned.

[Total madness]

M350d or m250d any deay of the week !!!

[Boss330]

4 turbos!!!!

[WreckerX5d]

I'll take one in a F80, and then straight pipe it.

Yep would make a sensible sub M3 performance model and we could have it as a tourer too

Probably never happen despite BMW trademarking M350d

[///mawana]

The turbo war just keep getting crazier!
