Some more clearing out, but first to correct a small expression error in my previous response.
I used reps. for revolutions instead of revs. (don't shoot me, I'm just a simple Dutch guy).
According to the Worldcarfan article about this new turbo-engine, this engine revs. up to 7000 rpm.
Verified this on the official BMW site, where this new engine is allready in the catalogue, and found out that 7000 rpm was the correct number for the max. engine revs. (redline)

The above link concerns the new BMW 335i coup?.
Here below some coppied highlights from the Worldcarfans article.

The engine reaches its peak torque of 400 Newton-metres or 295 lb-ft without any noticeable delay, maintaining this high level of torque consistently all the way from 1,300?5, 000 rpm. And even that is not all, with the engine revving up smoothly all the way to the 7,000-rpm range. This offers the driver a particularly superior style of motoring dynamics, enabling him to complete even the fastest overtaking manoeuvres in relaxed style: The new BMW 335i Coup? accelerates from 0?100 km/h in just 5.5 seconds, with acceleration from 80?120 km/h in the car?s second-highest gear taking an equally impressive 6.2 seconds.
This ongoing power continues unabated all the way to 250 km/h or 155 mph, where the speed of the car is limited electronically. Average fuel consumption under the EU standard, in turn, is just 9.5 litres of premium fuel/100 kilometres (equal to 29.7 mpg Imp), that is a consumption level very moderate for a car of this class and with this performance.

Another highlight in engine technology boasted by the new BMW 3 Series Coup? is the most sporting and dynamic six-cylinder diesel in the world: This 3.0-litre power unit featuring Variable Twin Turbo (VTT) technology, piezo-injection and an all-aluminium crankcase develops an equally impressive 210 kW or 286 hp, 580Nm of torque from just 1,750rpm through to 2,250rpm capable of continuing to rev up to 4,400rpm.

Who ever claims you can't use a diesel-engine in a sportscar or roadster, please reconsider that statement.

The diesel-engine mentioned above is the new version of the old 3 liter which previously was fitted inside the first BMW 535D, 268 hp, which had a cast-iron crankcase with an engine-weight of 228 kg.
The new engine has an all-aluminum crankcase with cast-iron liners, this engine weighs 203 kg.

Just a big fan? , my bankaccount gets very mad at me when I even think about mentioning Z4 .

Have to win a jackpot somewhere someday .

About the Z4, I realy wouldn't mind if BMW would equip the car with the 3 liter 285 hp/580 Nm twin-turbo diesel-engine.
I think this configuration would apear to be very though competition for the M version, on all fronts (specialy fuel-economy).

The law of torque still stands firm, it's the torque-part in the powerplant that makes the car accellerate (not the horsepower).

Science says: T=(60/2pi)*(P/n) >> where T stands for torque, P stands for power in Watts, n stands for revolutions/min, where 60/2pi=9,55.

Oeps where on earth have I seen this before?

By the way, to convert kilo-Watts into horsepower, just multiply the kilo-Watts by 1,34

you probably shouldn't compare your truck with a 335d...

ofcourse a 335d is in the planning, according to BMW's latest press-news (also includes full-specs of the 335d):
First all-aluminium diesel engine weighing only 208kg (so it differs from the 535d engine)
2993cc twin-turbo diesel with 210kW / 286HP (@4400rpm)and 580Nm torque.
