2011 BMW 3 Series (Special Sport Model)
Just 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.

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.

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 think the only really exciting news is the DCT.

The Best of Mercedes & AMG
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.
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'll be worried once they have a exhaust manifolds for bigger turbos. Then i might upgrade to one.
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. :)
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.





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

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