I hope this motor is in the 335ci/i.

It seems to me that a lot of people who have E90 325s and 330s will be trading their cars in for the faster versions, which will probably reduce their resale value. I wonder what that will do to E46s...

I doubt that alot of people will do that. There will be a select few who make that trade.

My current car is a turbocharged car. I would much rather have a naturally aspirated car than this. Much smoother than flooring the car, waiting 2 seconds, and then a blast of energy unnerving you.

volvo s40. Don't get me wrong, especially after it was chipped the car is pretty damn quick, but I would prefer to have a smoother engine.

that won't be the case in the N54...this engine is a bi-turbo engine (not twin turbo). It has two different turbos. A small, fast spooling turbo for low RPMs, and a Large turbo for higher RPMs. So the power delivery will be very linear, nothing like the typical turbo engine.

EDIT: check out the original post, 400NM of torque available from 1800-5400 RPMs with a redline of 7000, that's alot of torque down low for a turbo engine.

Granted, maybe not a lot, but I still fear for my cars resale value.

EDIT: of course the e92 will follow the same engine pattern as the e90 so what I said above is intended to apply to both the coupe and sedan.


there was a more recent turbo model i wanna say it was a 5 or 7 series that had a turbo gasoline engine, but I don't recall exactly what is was, but the 2002 was the most well known and praised turbo BMW

Sounds about right.

Even sequential set-ups experience minor lag.

Are you sure they're different? I see two, fairly similar turbos attached to 3-cylinders each.

If the engines both get upgraded, the same thing will happened as happened in thhe e46 after the engine upgrade. the 325 and 330 e90's will go down in value a little bit, but the e46 shouldn't be anymore effected than it was with the release of the e90. You gotta realize that the average 3 series car buyer is not someone who changes cars every year, so the majority of 325 and 330 e90 owners will not trade their cars in, until later down the road.

Google translation of press release:

The result is readable in the values of 225 kW/306 HP as well as the maximum torque of 400 Newtonmeters and witnesses from an impressing and already thrust using at low numbers of revolutions. Which means this for the driving experience, the engine developers by the example of a sedan of the BMWS of 3series row calculated: In acceleration from zero on 100 km/h the Bi-turbo--variant would be therefore faster around more than a half second, the elasticity value (80 to 120 km/h in the second highest course) could itself from 8.2 seconds for the strongest suction engine variant, which BMW 330i, on 6.3 seconds to improve. While maintaining the suction engine concept a such increase in dynamics would have been realizable only by a substantial extension of the capacity, connected with an appropriate gewichtszunahme and the effects resulting from it on the vehicle balance. On the other hand proves the employment of the turbocharger technology in connection with the High Precision Injection as a particularly efficient method, in order to fulfill still higher requirements to the achievement and the torque of the engine. To the comparison: The new Reihensechszylinder Bi turbo weighs about 70 kilograms less than a similarly high performance eight-cylinder August engine with a capacity of 4,0 litres. Beyond that exhibits the engine equipped with High Precision Injection opposite a equivalent strong turbo engine with suction tube injection a consumption advantage of approximately ten per cent.

Apart from the small weight and the values consumed favorable for its performance class the new Bi-turbo--drive can offer a further quality criterion of the row six cylinder engines of BMW. It offers outstanding quiet running and thus exactly that virtue, with which the row six cylinder engines became propulsion technology, cultivated recognized world-wide, from BMW to the yardstick for. Already the cylinder arrangement gives a balanced character to the engine concerning the free mass forces - also at high numbers of revolutions the engine acts vibration-free. In addition had also the turbo-variant of the six-cylinder of the suction engine particularly light cam shafts, the variable cam shaft adjustment double VANOS admitted as well as over an electrically operated water pump, which works only according to the respective cooling need.

The turbo-hole is past. With the new engine variant engineers of BMW succeeded in eliminating the construction dependent disadvantages of earlier turbo-prop engines. Therefore the loaded six cylinder of BMW does not show also for turbo engines to today typical characteristics: The thrust only using with delay is just as strange to the new drive as the high fuel consumption of conventional turbo aggregates. For a clearly more spontaneous achievement development provides in particular the Bi-turbo--concept. In place of a large loader two smaller copies supply in each case three cylinders with compressed air. Substantial advantage of the small dimensioned loaders is their small moment of inertia. Already the easiestImpulse, which the driver with the accelerotor pedal produces, is answered with immediate pressure build-up. The turbo-hole - that moment, which passes, until the loader takes up its work-promoting effect -, so far typical with loaded engines, is not perceptible therefore any longer. In driving the rating of the new turbo-prop engine resembles therefore the force development of a clearly capacity-stronger suction engine. 3.0 available the litre aggregate makes its imposantes torque of 400 Newtonmeters without noticeable delay and over the broad number of revolutions breakdown from 1500 to 5,800 min-1 away. And thus not enough: The engine winds up strong into the range from 7,000 min-1. The driver particularly experiences one sovereigns form of the dynamics, which it him permitted to complete also brisk acceleration maneuvers eases.
Double progress: high achievement, high efficiency. In order to bring a fascinating driving experience with values consumed up-to-date in agreement, BMW developed a row six cylinder petrol engine with Bi-turbocharger, fuel direct injection and full aluminum crank case as world-wide first a car manufacturer. The conception of the turbochargers already makes a contribution for consumption reduction. Because the turbines consist of high-temperature resistant special steel and bear temperatures of up to 1050 degrees, can be done without the refreshing effect of a increased fuel supply. Straight ones under full load result from it noticeable consumption reductions.

The key function in the concept for as economical a handling fuel as possible comes however the High Precision Injection. The new generation of gasoline direct injection fulfills also in practice expectations set into it regarding economy, without thereby reductions would be necessary with the dynamic qualities of the engine. High Precision Injection permits a more accurate mixture dosage as well as a higher compression - ideal conditions for an increase of the efficiency and a clear reduction of consumption. This becomes possible due to the central placement of the Piezo injector between the valves. In this position the new injector opening outward can distribute the fuel conically and particularly evenly in the combustion chamber. With the development of the new row six-cylinder with Bi-turbocharger and direkteinspritzung BMW opens a new chapter for already an engine principle quite old in the reason. Nevertheless could only recently the 100. "birthday" of the turbo engine to be celebrated. In November 1905 of Swiss engineer Alfred Buechi to the patent announced loader

Evidence shows (and most people here agree) that FI engines are easier/cheaper to get power out of. It's unusual then that BMW will put a 400hp V8 into the M3 and a 306hp Bi-Turbo I6 into the 335i. Wouldn't it be very easy to bring them close in performance for less money than the M3 will cost?

Question - is the upcoming m3 going to use the e39 m5/z8 engine?

Supposedly, it'll be a V8 version of the V10 from the new M5/M6.

No i believe its a variation of the current M5 engine with two less cylinders.

I retract whatever it is I said about never ever considering an E90.
