2012 BMW M5
Diesel M5 will have less horsepower than gas version, but loads of torque

In Europe, the diesel engine has been a staple in automobiles due to its fuel efficiency and the price of gasoline. However, there are relatively few diesel cars in the U.S. even though the engines are common in heavy-duty trucks.

BMW has confirmed that it will be producing the first diesel vehicle to ever wear the M badge in the company's performance vehicle line. BMW will be producing a diesel-powered M5 next spring that will feature three turbochargers. The same engine will also be used in other BMW vehicles like the X5 and X6 crossovers.

The Detroit Bureau reports that the vehicle will be called the 550dM or the 550dXM with the latter featuring an all-wheel drive system. The Detroit Bureau also reports that the diesel engine would be a version of the current straight-six diesel beefed up for M duty.

If the engine is in fact a straight six, it will reportedly use one small turbo to build boost for launch, while two larger turbos will come online for extra mid-range and high-end power.

The publication also claims that sources have told it that the 550dM will make "slightly less" power than the gasoline M5's rated 560 HP output with final numbers expected to be in the 500 to 550 HP range. However, the torque output will be massive at up to 650 lb-ft. The copious torque is pointed to as the reason for the all-wheel drive option.

"You have to go to all-wheel-drive,” explained one senior BMW official, “otherwise you’ll be spinning your tires all day."

GM will be producing a diesel version of the Cruze as well, though it is far from a performance vehicle. However, this shows that the trend in using diesel engines in the U.S. is growing.

With diesels traditionally more expensive than gasoline engines (at the same power level), price may come into play for the M5D. Especially that we are talking about a 500HP+ diesel with three turbos.

Nothing about this car will be cheap.

Might as well become close friends with a tire shop too. 20,000 miles on a set could be generous with this beast.

These cars are typically staggered so you'll go through the rears much quicker than the fronts.

You're telling me! BMW's are already expensive to service, but a three turbo diesel monster like this? Tires will be the LAST of your concerns whenever this baby rolls into the shop.

As a car enthusiast and auto-x amateur, I really HATE what BMW has done to the M5 with every new iteration that's released. But this? M5's have already gotten too far from the fun, light, and sporty vehicles that made it a legend to some. Now what is this? An all wheel drive pig with an M5 badge stuck on. An all wheel drive M5? Blasphemy!

All the power and turbos in the world won't give the M5 back that which it has already lost. :(

Its the perfect leasing machine that gets about 30mpg on the highway.

I don't know. I like it. When you slap two extra doors on a car, a car maker can make it anything they want for the most part. A little harder to do with two seat only cars (thank God). I'm not too happy with BMW's direction either but, IMO, it fits with the people that actually buys these things. Their core buyer was never the sports car owner but someone that wanted practicality with much better than average performance. The M5's direction doesn't surprise me any.

When was the M5 ever considered a "light" vehicle (compared to its contemporaries)? Even the much loved E39 M5 weighed 4,000 pounds.

It was nimble and light "feeling" despite it's weight. All that is ruined when you start talking about AWD turbo'd out the ass diesels. I drive an AWD car daily, so I know what I'm talking about. True sports cars in BMW fashion are rear wheel drive, everyone knows that.

And the E39 sure weighed less than this thing, didn't it??

P.S Brandon, the M5 didn't HAVE any "contemporaries". It stood alone, and that's all I have to say about that.

The E39 is about 300 pounds lighter than the F10

Do you even understand my point that M5's keep getting heavier and heavier? I'm not sure why you're fixated so much on that one statement I made and taking to completely out of context. Stop trolling!

And I love how you so easily dismiss a 300 pound gain when it comes to a performance vehicle. Tell you what Brandon, carry around 300 pounds for a day and tell me how "light" it is.

Of course I understand your point, and I'm not trolling.

All I'm saying is that relatively speaking, considering that all vehicles have gotten heavier in the past decade due to added safety/features/emissions controls, a 300 pound increase for a midsize sedan is not all that bad all things considered.

So my point still stands that the E39 was no lightweight in its day, just like the F10 is no lightweight today. It might have been nimble on the track, but it was not a light vehicle by any means. I don't mean it in a bad way, just stating facts. Everyone just makes up for it today by adding a s**tload more power across the board compared to their counterparts from a decade ago.

Anyway, for comparison:

2000 BMW E46 M3 -- 3,415 lbs
2011 BMW E92 M3 -- 3,704 lbs

2000 Audi B5 S4 -- 3,338 lbs
2011 Audi B8 S4 -- 3,638 lbs

2000 Mercedes E55 -- 3,680 lbs
2011 Mercedes E63 -- 4,084 lbs

Anyway, no need to get your panties in a bunch. We're all friends here ;)

So do you prefer the E35 or the E39?

While I respect the current M5 those two are the ones for me (and I have a hard time picking one over the other).

As for the coming M5's I think we should wait to judge - the world is changing and cars are infused with new tricks all the time. Look at the first words on the Porsche Panamera Diesel - while it's still big and ugly it may be the Diesel is just what it needed.

I wouldnt be too quick to judge this car. BMW's M division performed miracles in making the X5 M and X6 M corner like cars less than half their weight. And it sounds an awful lot like the engine they will be using in this car is a modified version of the 335d's engine. Given that engines aluiminum block is already lighter in the X5 35d than the 4.4L V8 in the X5M by close to 150 lbs, its plausible the RWD 550dM(the article clearly states it is not getting an M5 badge) will weigh less than the RWD M5, and the 550dXM will likely be roughly the same weight. Granted, that third turbo and its plumbing will add some weight back, but not 150 lbs of it.

besides, every one of these that they sell will increase their CAFE number meaning it leaves them freee to build more M3's, 1M coupes, and (god willing) M1's.

Weight balance is gonna suck in this thing. Three turbos + diesel engine + piping is gonna weigh quite a bit.

Its also going to drink AdBlue like an alcoholic Smurf. But its going to be insanely fun to drive. Have to admit, haven't been this giddy about a car in a very long time.

Wonder how long before some rich hippie runs straight WVO through it.

Meah, it's got less HP than the gas version. Sure, low end torque is great and all, but that's all diesels have. How long are you going to own this thing before you get tired of feeling like you are driving a school bus everyday?

I want a sports car that can rev, one that sings to me. Not one that burps and gurgles along like a tow truck. Diesels are BORING.

My dream car is a 67-69 Camaro with a turbo diesel.

And if you think diesels are slow, tell that to guys with F250s and 2500HDs running 10s and 11s in the 1/4 mile. High revving doesn't mean fast. Sure it might sound good, but sound != power. A Honda Civic Si can be loud at 9000 rpm. That doesn't mean its fast.
