Just thought some would find it interesting.

I deleted your other thread.

BMW using turbos is kinda old news don't ya think?

TopGun32

those are very conservative numbers for a 3.0 L bi turbo engine...

my guess that TUNERs will have a field day with this engine set up.

One small turbo and One large one... perfect!

I could see this engine making 375hp+ with very simple mods (conservative)

ProjectC55

Well it's nice to see they are putting them on N/A engines again.I hate to say it but if this thing comes out here in the US there's gonna be a HUGE aftermarket upgrade for the TT BMW 3.5 liter motor ala Supra 3.0L TT.
Potentially beating the E63 and W211 E55 if properly modded like a modded SupraTT.

has there been a bmw with a turbo engine in the past?

AMG_55

2002 turbo

many diesels

ProjectC55

E23 745 turbo in the 80's as well.

From BMW Press Club Site (German):

N54 Bi-Turbo engine with HPI direct injection.
306HP, 400Nm available in range 1500 to 5800rpm. Max 7000 rpm. With full alluminium crankshaft casing, Bi-VANOS, electric water pump. 70kg less weight than 4.0L V8 NA engine. No turbo lag.

Tested in E90:
80-120kmh in 6.3s (eg. 330i in 8.2s)
0-100kmh in 5.7s (eg. 330i in 6.3s)


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.

ProjectC55

I'd purchase it and build it to murder the new M5! I see alot of potential there.

e1000

That would be funny if the 335i cannibalizes sals of the new M3/4 and M5 because of it's moddability.

ProjectC55

Absolutely! I think the TT car would be a no brainer especially pricewise compared to both the M3 V8 car and the V10 M5.

Let that car come to the US and it's good bye to all my German toys other than my 4cyl Japanese beast.BMW all the way for me in that case! No questions asked especially if it will come as a 6 spd manual shift and not that stupid SMG crap!

AMGSC

I know Mech Tech is offering a special of TurboCharging BMWs I don't recall from their advertisement what year and what models.

sdsilverm3

They used to (still do?) have a kit for the E36 M3 that used a self-contained turbo (no oil lines needed). There were a lot of mixed reviews about that kit. Most E36 people chose to go the AA route.

TopGun32

finally a good choice for BMW...

N/A engines are great... but there is nothing like a Bi turbo set up or kompressor... so much more potential.

The coupe 335 will be hot!!...

i have seen some spy shots...

take a LOOK!

LOOKS HOT!!

e1000

If that's the coupe then it might not be a total loss like the sedan.

TopGun32

correct...

let's see..

RWD,

coupe,

manual transmission

bi-turbo

The rear is ok, and I bet the front end would look like the new 3.

so far so good!

I say... look out G35, IS350 and even CLK350/550. Stock it will be a fine performaner, but MODs will make it a nice little beast like the C32.

By no means I'm turning to the dark side, but it shaping up to be a good product. Let's wait an see.

FrankW

it's gonna be a very moddable engine for sure, but one thing you gotta ask is that would you pay $50-55k for a 3-series given that it is not an M3.

If they put that in the 5-series...I'll be all over it!!

TopGun32

here are final production pics of the 335...

wheels look bland, but I bet those are not the sport package wheels..


the stylying is not too bold and not too boring. Just needs better wheels, a slight drop and more boost.. and Manual transmission.

good job for BMW on the 3.0 biturbo.

I love the power that you can get out of a turbo but my friends have had TTs, S4s (B5) and STIs. I saw them run into a lot of problems when modding turbos...especially the S4 my good friend went through 2 sets of turbos. My brother had a 99 M the car itself didnt hold up that well, but the engine was still good when he traded it in for his cts-v in december. I wonder how a bmw turbo would hold up with mods.

TA-9FF

Geez.

I'm just out of words to say. BMW STILL can't design their cars. Maybe they should take the Volvo route and get Pininfarina to design some of their stuff.......at least it'll LOOK great. Am I the only person here to not care for current BMW design? (or lack thereof)

e1000

right there with you. better than the sedan but still not anything near the E46...

1sikbenz

Coolcarlski43 - you're right all the way, some of those boosted 3.0L Supras spank Lambos all day long, you never know when one of those damn things are gonna have 1200-1500 h.p., it would be crazy if someone could do it with a 3 series, also that would be funny if these T.T.'s beat out the M3's in sales, but if your gonna lose your Benzo & get a Bimmer, I got dibs on your C55! - BTW - are both the black & silver cars yours?

TopGun32

complety agree with your statement..

this car will be a tuner's dream...

think of all the tuning it takes for the current E46 to make decent power.

and now think of the tunning potential of this engine.

I can't wait to see one in person.

I love to get an E55 (power, luxury, class) but the 335 will be fun, newer, full maintanance and full warranty, smaller but more sporty.

I know I should not compare the two, but the price point of both cars will be the same..

high 40's to mid 50s for a used 03 E55
high 40's to mid 50s for a new 335i

300/300 hp and torque...

its a nice foundation to start...


i think I might be going to the dark side.

TA-9FF

Allow me to retort.

I'll go to the dark side..............when I can stand to look at their cars again without vomiting "Bangle-sized" chunks all over my non "flame surfaced" self.

They should bring BACK the E46 and E39..........................lol
