I know 335is has different motor but why does it have more HP and is suspension same as 335i?

The additional HP probably has to do with twin turbos vs twin-scroll single turbo.

The suspension should be the upgraded springs from the performance catalog. All the IS really is is a lot of badging and basically the entire performance kit installed.

If you're talking about 2007-2010 335i yes it has twin turbos coup and sedan. If you are talking about 2010-2011's they are the ones with twin scroll single turbo. The 335is is as you said a basic 335i coup with performance parts already installed. You get all the cooling upgrades, suspension, exhaust, and mtech kit.

it still doesn't have an LSD, correct?

effing BMW...

Wrong. It's 2007-2010. The 2010 I have has the N54 twin turbo engine. N55 starts with the 2011 model year. Yes, the cooling upgrade is part of the Performance Power Kit (with upgraded ECU settings for the additional torque boost), exhaust is the Performance Exhaust, etc. Again, the whole setup is a bunch of badges and everything from the performance catalog.

Only the M.

[dryicerx]

The biggest difference is the availability of the DCT transmission, which is non-existent for a 335i.

Correction: DCT is not available for US 335i, but available in other countries.

i think the 335is is redundant

[hipnotic]

more hp and more torque and different body kit on it

[KevinJ]

1. The 335is comes standard with a version of the M body kit. It includes a sculpted rear valance (diffuser) matching the body color versus the standard M kit which is black ABS only. The standard M package also includes sports suspension and other M bits such as thicker steering wheel, chrome accent peddle and foot rest, M door sill badging.
   
2. Black chrome exhaust tips, grill and shadow trim, and anthracit headliner unless comparing to the M kit only exhaust tips different. Black mirror caps also which are not part of the M kit.
   
3. The exhaust is a modified sports exhaust and not the standard BMW sports exhaust. According to BMW, they removed some of the fill to change the sound and also added a valve like a standard exhaust to control the noise where the normal BMW sport exhaust doesn't have this. The 335is exhaust differs from the 335i, 335i with M kit, and BMW branded aftermarket sports exhaust.
   
4. Also according to BMW the motor mounts are stiffer than a standard 335 and not available on the standard M kit. The suspension is no different however or the brakes.
   
5. There is the availability of the DCT transmission which you can not obtain on the standard 335i or 335i with M kit unless outside of the U.S which varies by country if available on the 335i.
   
6. The 335is uses the older N54 Turbo motor where the 2011 335i uses the new N55 Twin Scroll motor. 335is only exists as a 2011 and thus can't compare to prior years. Tunability or other unknown factors may come into play with the N54 versus N55 and why it was chosen for the 335is. It was remarked that BMW had more experience on the N54. N55 335is in the future? who knows.
   
7. The 335is includes tuned sports software not standard on the 335i and M kit. The 335is gets 320 hp and 332 lb-ft torque from the twin-turbo 3.0-liter inline-six engine, and an overboost function allows for seven-second blasts of 370 lb-ft of torque. Compared to the standard 335i with 300/300.
   
8. The 335is has additional radiator, oil and a larger cooling fan compared to the standard 335i or 335i with M kit. "An additional radiator has been added behind the left-side front air intake, along with a more powerful electric cooling fan. An oil cooler is fitted opposite the second radiator, on the right side."
   
9. Foglight delete for better air cooling to support the additional radiator and oil cooler and not an option on the 335i or 335i with M. 335is convertible retains foglights.
   
10. The 335is includes a 335is cluster gauge with color/badging. There is unique 335is badging on the outside and inside.
    
11. The 335is comes standard with 18" 313 wheels compared to the standard 335i. The 335i M package no longer offers the 313 wheels standard.
    
12. The 335is comes with paddle shifters standard.
    
13. The 335is offers a sunroof delete option. This option may be available outside of the U.S. or on request for other 3 series models.
    

All of this is about $3-4k more than a standard 335i. I think its a good deal. The only thing I would wish for is a factory option for BMW performance brakes or at least some type of BMW or M branding on the brakes and cross-drilled brakes all around for looks.

Other food for thought:

Performance figures split the siblings perfectly in thirds. We find the 335i Coupe to have a 0-60 acceleration time of 4.8 seconds, while the 335iS finds 60 in an estimated 4.6 sec, topped only by the M3’s 4.1 second acceleration time. Power figures follow a similar trend, the 335i Coupe outputs 300 hp / 300 lb-ft torque while the 335iS turns 320 hp / 332 lb ft of torque, topped again by the mighty M3’s 414 hp / 295 lb-ft torque. The curb weight of each car tells a different story; to summarize, the 335i Coupe is laden with 3,542 lbs, the 335iS with 3,650 lbs while the M3 tips 3,704 lbs at the scales.

The only downside is fewer exterior color choices and only Dark Glacier Trim is available.

It also includes an anthracite headliner (don't believe this something you can get on a standard with M package).

I believe it actually is included in all M package vehicles.

[redline2001]

As kevin said the suspension is unchanged, the article BOLDLY states so.I do believe that the anthracite headliner comes stock with the M package.

[Quasimodem]

It's the old 335i with some performance improvements and cosmetic changes which are carefully engineered to NOT look as good as the M3 body modifications.

I think theyre using up parts and trying to keep interest as model comes to an end. Porsche is doing the same thing with their GTS.

Unless you want DCT, something no mod will provide. And the extra power never hurt anyone.

[stressdoc]

IMO the 335is is a classic, the best enthusiast version of the 3-series ever. The E46 ZHP was great, but the 335is is a step beyond. Definitely not an M, but a big step in the right direction.

Problem for the 335is is the cheap and readily available tune market. If there were no 60+ HP $700 piggys and flashes, a significant chunk of E90posters would have jumped at the opportunity to spend a few extra $k for the 335is. But it was too little too late. Hopefully BMW will have learned from this that they must release performance models early in production, not as a last few years amp. The Mini has had John Cooper Works from early on. If you release a car as easily moddable as the 335, but don't fill the niche for performance upgrades right away, the aftermarket tuners will swarm in and cool the market for OEM products. Maybe it was the Dinan fiasco. Europe has had Alpina et al working with the factory. Things are different out here in the wild west.

I thought both cars had the N54 in them? Unless OP is talking about older 335's.

The 2010 335i still used the twin turbos.

Wrong, I ordered my 335i with 7-DCT and should be here this week

+1
It's a good value for all the features mentioned. I would have bought it when I was on the market. To equal it, you'll definitely spend far more money. And I do agree that BMW should have offered a Performance brake kit version for the 335i sport, not fair. That's why I went Alcon.

Not here in the US. We can't order that. And we hate you for it.
