Default BMW Confirms Diesel-M, High-Performance Engine to Find Numerous Other Applications


http://www.thedetroitbureau.com/2011...-applications/

Quote:
BMW will introduce a new high-performance diesel-powered 5-Series model next spring that will expand the German maker’s vaunted M division, TheDetroitBureau.com has confirmed, with the triple-turbo V-8 oil-burner set to also be used in a variety of other BMW products, likely including its X-series sport-activity vehicles.

Rumors of the diesel M have been circulating for several weeks, but TheDetroitBureau.com has confirmed details with a variety of BMW sources who say the maker wants to prove out the potential of the high-mileage technology – taking advantage of a variety of new technologies, including the unusual triple-turbocharging system meant to eliminate even the most minor turbo lag.

The new model is likely to get the unusual designation of either BMW 550dM or 550dXM, the latter referring to its all-wheel-drive system. With rare exception, most models produced by the Bavarian maker’s performance sub-brand flash the vaunted “M” first and foremost. But the alternative nomenclature would reflect the unusual powertrain under the hood of the 5-Series BMW.

The 3.0-liter straight-six diesel will use a small turbo to instantly build boost for launch, two larger twin-scroll turbochargers then spooling up for higher-speed performance. The basic engine is the same as the current BMW 3.0-liter diesel but with significant modifications, including a new cylinder head. It will make use of a variety of advanced technologies, including direct injection and BMW’s Valvetronic system, designed to optimize the function of intake and exhaust engine valves.

Sources tell TheDetroitBureau.com that the 550dM will deliver slightly less horsepower than the new gas-powered BMW M5, which makes 560 ponies. Final numbers will likely be in the 500 to 550 range. Torque, meanwhile, will well exceed the 500 lb-ft of the new M5, and could push north of 650 lb-ft.

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

(For a first look at the next-gen BMW M5, Click Here.)

While several makers have demonstrated the potential for diesel power on the track, the move to put it into a high-performance street car is a significant breakthrough. Mercedes-Benz briefly offered a diesel model wearing its AMG badge but that lasted only a year on the market. BMW has long considered the option but it took several significant developments for the company’s comfort level to reach the necessary threshold.

“Diesel technology has come a long way in the last five years,” said one BMW executive, adding that the maker also had to be certain buyers would be able to get the necessary quality of diesel fuel in any market – notably including the U.S. – where the 550dM will be sold.

For the record, M brand global marketing manager Brian Watts confirmed that the maker is looking at a diesel M car, though he said, “We’re not finished with that program yet.” But other insiders said only the final details, such as performance specifications – and the final brand nomenclature – have yet to be firmed up, with the new diesel muscle car due for introduction next spring, very likely with an unveiling at a major auto show like the Geneva Motor Show.

The engine is intended to find applications beyond the 5-series M edition, sources agree. It is designed to fit in a variety of additional BMW products and would most likely show up next in one or more of the maker’s X-Series Sport-Activity Vehicles, such as the X5 or X6. But a version of the 550d engine might also be melded with the maker’s flagship 7-Series sedan “a year or more later,” said a source.

BMW officials say they hope to steal a march on competitors – but, said one, “I expect to see others follow,” a reference to both Mercedes and Audi. The executive said he was particularly surprised that the latter German brand had not moved into the diesel performance segment more quickly, as it would play off Audi’s link to diesel power. The maker has dominated the Le Mans endurance series for much of the past decade with its various diesel-powered race cars.

Couldn't find a 4.0RS at sticker so I'm holding on that. Maybe a Scud this fall otherwise wait for a 4.0 to come up. I need a new truck but waiting for the Rover re-design and 8-speed next year unless the X5 comes with the tri-turbo diesel and 8-speed. M5 I'm keeping for now. Been thinking of building a Backdraft Cobra with the Yates FR9 Nascar motor carbed and tuned for 100 octane (have a few stations around). That's all for car buying thoughts for now.

How's the pressurized Cayman?

I'd get one for the wife and have grins with it on the sly... And enjoy it on the road trips. Wagon form and a stick shift and I'll buy one for myself. Not that THATS going to happen...

This is all well and good, but what I want is a 320d. There are plenty of high performance options in the US.

Yes. The 335d is nice and all, but $10,000 higher starting price than a 328i? Please.

its more of a 335i alternative, 328 dont have 400 lb/ft of torque.. and 335d is faster in every way than 328i... and more frugal.. and BMW has $3500-$4000 rebates on it all the time..

Not sure I agree. First off, the new 328 should be about as fast than the 335d. Looks to be making about 250-260 HP, and is lighter.

The 335d pretty much spits the difference between the current N/A 328 and the 335 in terms of acceleration.

So, while it's a closer alternative to the 335 on price, on performance, well, it doesn't necessarily line up that way and isn't considered a good performance value compared to the rest of the line-up.

Agreed.
Although, if I had extra cash to burn, I'd get myself a 335d in a heartbeat .

M is really departing from it's previous stance about only having high-revving atmospheric gasoline engines, for their pure rev response all the way to redline.

First it was turbos... Now turbo-diesel is rumored. I'll bet the redline on that is really impressive.

Ok. You go engineer a high revving naturally aspirated engine that meets emissions targets, output targets, and costs targets. Then get back to me.

Porsche 3.8 liter X51. 408 naturally aspirated H6 power.

Lamborghini/Audi 5.2 liter V10.

I am not an automotive power-train engineer, but others are.


BMW ///M division used to make statements about their engineering ideals, and how naturally aspirated high revving engines were their focus, and for real technical reasons. That isn't me talking, that was them, some time ago, now.

Evidently they hold to that about as well as Subaru holds to All-AWD, All-the-time.

Yeah we all know how BMW's V10 worked out in the emissions department... terrible fuel economy when put in those big boats. Their current n/a V8 didn't work out well either or they wouldn't have just scrapped it like that. The other problem with the high revving engines is that there is basically no application for them outside of these low production cars, so cost sharing becomes difficult.

For the record I like high revving n/a engines. But I think they are pointless in M cars because M cars are too heavy now and they've been that way for about 10 years. When I drove the now-outgoing V10 M5 a couple years ago I wasn't impressed because the car was too heavy. Big fat vehicles like that need torque.

Yea, 0-60 in 4.5 seconds(not on launch control) and capable of 200+MPH for being 4000+lbs, and being engineered in 2004 isnt impressive at all
