For 2011, BMW is slotting a new car above the 335i and below the M3, called the 335iS. Check this out for your Beemer aficionadoesJust another thing for us C32 and C55s to worry about ???)

The twin-turbocharged 3.0-liter inline six-cylinder engine of the 335iS adds a special software package to bump power to 326 hp and lift torque to 332 lb-ft--or to an even gutsier 369 lb-ft for short periods via an overboost function that unleashes added turbocharger boost pressure.

BMW puts the new 335iS's 0-to-60-mph time at just 5.1 seconds in standard guise, or an even sharper 5.0 seconds when running the optional dual-clutch gearbox--making it just a tenth of a second slower than the acceleration benchmark of the standard six-speed manual M3. Top speed is increased by 20 mph

Note too that the 335i (non-S model) will lose the twin turbos and perhaps the 135 will as well. The 335 will go with a single twin-scroll turbo instead of the duals of the "S " model.

Eh We should just wait and see. The power package just seems like BMW's version of a juice boxes thats out there already.

The single turbo is going to probably increase the turbo lag and the DI and valvetronic makes tuning more difficult.

So i'm interesting in seeing if the N55 as make as power as the N54.

My thoughts exactly!!! I find it interesting that their flagship three (3) series (the old 335i, aside from the M) is getting a single turbo (probably a cost savings). The "S" model, almost as quick as the M3, will most definitely cannibalize M3 sales if they can maintain the price point near the current 2010 335i model.

To be clear, the upcoming 2011 135i and 335i will be getting the new N55 TWIN SCROLL, SINGLE turbo N55 engine with direct injection and valvetronic variable valve lift. This new engine is 20kg lighter than the N54, and 10% more fuel efficicient too, while having the same power output of the twin turbo N54 (300HP/300 lb-ft). If you believe BMW, maximum torque comes even EARLIER than the N54, with a comparable flat curve, meaning that lag should NOT be an issue with this new single turbo engine, mainly because of the twin scroll turbo design.

Interestingly, the Z4 sDrive35i will retain the older N54 twin turbo engine with direct injection.

The 335is coupe/cabrio and Z4 sDrive35is will use the N54 twin turbo engine with direct injection, along with upgrades to increase HP/torque to 322 HP and 332 lb-ft (with 369 lb-ft as a tempoary over-boost function). This upgraded N54 will have an additional water cooler and high output cooling fan. I suspect this is similar to the BMW Performance Performance Power Kit which is available to all 135i/335i owners with the old standard N54 engine (except for the temporaray over-boost function).

Both the 135i/335i and 335is/Z4 sDrive35is will be available with BMW's DCT (dual clutch transmission), which should also aid in lowering acceleration times because of much faster shifts.

My vote-I have one that I'm ordering on now...should be a kick *** car-even the wife wants to take it to the track!

I dont think BMW would lose too much money even if it did cannibalize m3 sales. A fully load 335i is pretty close in price to a base M3, I suspect there cost to produce the 335i is slightly slower since they make quiet a bit more N54/N55 engines then the lower volume 4.0L v8.

I think the only really exciting news is the DCT.

TemjinX2

are you going to get it with the pdk?

Autoweek's take on the same basic info:

Do you think they underrated the N55 motor just like they did with the N54?

Besides Newz, These cars have been out for a while. They are so cheap to mod, every one of them is running a juice box or vishnu tune. All the time I see these 20 year old kids that have a juiced up 335i. One 20 year old told me his 335i is running high elevens at PBIR. Prob all talk. But he claims he's pulling on C63s all the time.

Eurocharged was tuning a 335 at the tuning day in Jersey this weekend and it gained 60 hp and about 100 lb-ft torque. I forget what the total number of hp was, but the torque was 405. The car only had an intake. Blew my my mind.

...base 335's are something us c32/c55 guys have to worry about anyways considering that they dyno at ~270 at the wheels, making really closer to 340hp rather than 300...and for several hundred dollars they can be pushing 370hp at the wheels....

My brother has a chipped 335i, that thing is beast. I'm unsure on 0-60, HP, and torque.
BMW severely underrates their HP/0-60 times.

In 2012-2014 BMW will be releasing the model of the 1 series, 3 series, and a M model of the 1 series. (not going to be called the M1 for obvious reasons) Can't wait to hear about the new engines, designs, etc for BMW.

i'm seeing most 335i's toping out at around 387whp with intercooler, down pipes and intake with a juice box on 91 gas. Silverbullet amg dyno'ed 384whp with a 185, let tune, headers and intake i believe.

I'll be worried once they have a exhaust manifolds for bigger turbos. Then i might upgrade to one.

Respectfully disagree.
Their “base” 135i/335i models have thus far been relatively easy pickings during off-highway road course encounters.
Only fair to disclose that mine has been (conservatively) modified for just such occasions.

Have witnessed tweaked N54s laying down solid 11-second/120+ mph ‘strip results during a recent GTG.
They’re not to be trifled with during the casual stoplight grand prix.

Kudos to Bayerische for stepping up their OE offerings a notch.
They’d be mighty tempting if it weren’t for their off-putting SoCal douche factor. :)

Yeah-my C4S is a stick and I like it-but the new PDK is insane on the track-much fast then what I can do-and it lets you hold gear and bump w/o thinking it knows best-
there are a couple 335's running around MSP here and they aer trying to get Evo's to run with them-the Evo guys are still laughing-the 335's are decent-its a turbo 6-but for the $-I'd take a IX or X and run 10's all day at lower cost and better (imo) reliability. I can see the M3 losing the V8 and gaining a better 6TT (Borg Warner mid range size)-
as for mani's and bigger spoolers-most guys are going with stock housing's and larger turbine wheels in side (think T4 inside a T3)-Forced Performance has been doing it to Soobies and Evos for a while with great results and stock appreances-great spool time, improved mid and top end.

In regards to the speed/horsepower wars, I'm not concerned with anything that's more than 5 years newer than my car. As more and more power is made, you can't compete newer cars with older cars.

rockjock

I would respectfully decline on that one....I hear there are some 50-70's cars that make some decent powa at the track
I get what you're saying tho-1990-2009 production cars vs each other is one thing-but running a 95 vette against a 2010 C63 isnt really a comparo-
I still think people need to pick thier street wars carefully-and better yet-go to a strip or track and see how the driver and the car does, not just the gas pedal.

TemjinX2

Yeah i agree, its easy to keep up if you have a Japanese import or Domestic V8, 2jz and LS7 comes into mind.

Its just outrageously expensive to mod a mercedes or BMW to be fast.

TemjinX2

I drove my friends 03 911. I use to think people say it has one of the best manuals in the world just because its a porsche. But i was pleasantly surprised when the shifter really did shift like butter.

Good luck on the boxster...the pdk i think is a good compromise between track and daily driving.
