BMW to Debut New 3.0-liter Twin Turbo Diesel with 306HP on 735d

BMW has confirmed the development of a new and more powerful version of its acclaimed 3.0-liter twin-turbocharged straight-six diesel engine. The new 3.0-litre TwinPower Turbo diesel unit that churns out a maximum output of 306 horsepower at 4,400 rpm with a peak torque of 600 Nm or 442 lb-ft at just 1,500 rpm, will replace the current 3.0-liter inline-six diesel in the 735d, 335d, X5 35d etc that produces 286HP at 4,400 rpm and 580Nm or 428 lb-ft at 1,750 rpm.

The Bavarian automaker supports that while the new engine is more powerful than its predecessor, at the same time it offers some 4 percent lower fuel consumption and CO2 emissions - not bad. BMW said that the 3.0-litre TwinPower Turbo diesel will make its premiere on the 735d later on this year with other models following soon after.

I thought there will be tri-turbo diesel for 7-series.

So is it same as the new engine for 335d?

I believe so, will be intro'd in 7er, then in others.

Perfect engine for the F01!!! So this would be my choice…must be drive like hell - after all the positive results for the 730d already…

dr Dunkel · 06-23-2009, 03:52 AM

I would also surely go for this engine in the F01. Diesel is king for this type of vehicle.

From the official press release ...

Quote:

Introducing an additional top version of the six-cylinder diesel already featured in the BMW 730d and the BMW 330d, BMW once again proves the outstanding potential this engine technology has to offer. Again, the new generation of BMW’s straight-six diesel, combining multi-stage turbocharging with common-rail direct fuel injection, offers fascinatingly dynamic power and performance with maximum efficiency. And again in the spirit of BMW EfficientDynamics, numerous innovations on the all-aluminium engine as such, the two turbochargers and the injection system ensure a significant increase in power as well as a further reduction of fuel consumption and emissions. Not only the turbocharger system is even more efficient than before, but also the supply of fuel through piezo-injectors operating at an injection pressure of up to 2,000 bar.
The new 3.0-litre BMW TwinPower Turbo diesel delivers maximum output of 225 kW/306 hp at an engine speed of 4,400 rpm, with peak torque of 600 Newton-metres/442 lb-ft at just 1,500 rpm. These figures alone allow the new engine to take over the leading position from its own predecessor as the most sporting and dynamic six-cylinder diesel in the world, at the same time offering some 4 per cent lower fuel consumption and CO2 emissions.
BMW’s new eight-speed automatic transmission: the intelligent way to more gears, greater efficiency and enhanced driving dynamics.

Great. Fantastic even. A 3.0 liter bi-turbo diesel with 306 hp/600 Nm. The 745d 3.0 tri-turbo will have around 360 hp...

And the 7er finally gets the 8 speed automatic it seems Eni?? Good! Shoud've been there from the start on all engines, but starting with a 300 hp diesel is ok too

And I thought it was the case but I forgot....did the 8 speed have a start-stop function???

7er already features 8-speed gearbox - in 760i / 760Li models.
7er Hybrid will be next - incl. Automatic Stop-Start function, which is a feature the new gearbox is capable of.
But it will be initially introduced in Hybrid models.

BMW’s new eight-speed automatic transmission: the intelligent way to more gears, greater efficiency and enhanced driving dynamics.

BMW’s new eight-speed automatic transmission is yet another example of how outstanding engineering qualities are able to offer a significant improvement in driving pleasure and, at the same time, far greater efficiency than ever before.
This innovative power transmission first introduced in the twelve-cylinder BMW 760i and BMW 760Li excels in particular through its exceptional efficiency and wide range of qualities. At the same time, through its special characteristics, the new eight-speed transmission raises both the motoring comfort and the dynamic performance of the respective model to an even higher standard.
Yet a further important point is that this significant progress over BMW’s six-speed automatic transmissions already lauded the world over for their superior gearshift dynamics and efficiency has been achieved in a particularly intelligent manner. The two additional gears give the entire transmission an even broader range of increments and, at the same time, keep the change in engine speed when shifting from one gear to the other even smaller than before. Thanks to the innovative configuration of the gearsets, the number of additional components required and, accordingly, the weight of the new eight-speed automatic transmisson, has been reduced to a minimum.
Converter slip limited to the lowest range of engine speeds, a high degree of inner efficiency, low frictional losses with only two clutches open at a time, the longer transmission ratio of the higher gears, and the improved suppression of vibrations enabling the driver to use the car much more at low speeds, help to reduce fuel consumption versus the former six-speed automatic transmission by approximately 6 per cent.
A further important point is that the eight-speed automatic transmission enhances the dynamic qualities of the engine by opening and closing only one clutch at a time in nearly all gearshifts, even when shifting down by more than one gear. This offers an important benefit so far provided only by the double-clutch gearbox and combined in this case with all the benefits of an automatic transmission relevant to the customer, such as dynamic acceleration from low engine speeds.
The new eight-speed automatic transmission is also a particularly future-oriented solution for the transmission of power in a premium car. It may be combined with all kinds of engines varying in their design and performance, being used not only in cars with rear-wheel drive, but also in all-wheel-drive models. And at the same time the eight-speed automatic transmission also has all the qualities to form a perfect combination with hybrid drive. This alone ensures a unique blend of efficiency and dynamism on a brand-new level, proving that this concept perfectly suited for the future will be heading for success after reaching production level in the course of 2009.

BMW marketing tonsils.

Now they're calling everything with a "twin-something" turbo "TwinPower". So, the new twinscroll, single turbo in the petrol 3.0 is TwinPower and this new multi-stage dual-turbo arrangement is so-called too.

We need more information on this. Is this the latest in the 35d (M57TU2D30) engine technology that featured multi-stage, sequential turbocharging? Do they now combine this concept with twin-scroll turbocharging? Certainly seems that way...

Yes, now everything is TwinPower Turbo

There will be MultiPower Turbo as well ... soon enough.

Soon.

My sources say the new engine will be premiered together with xDrive - in a single model. Expect M Sports pack introduction in the same time as well. And Hybrid model is also somewhere there. There is certainly much going on in the 7er field.
