They are NO slouch - easily pull a low 13 in the quarter mile STOCK I would think.

My 1.47 procede could only keep up with a 335d on a private track where we were hitting 140 + down the backstraight.

Now I run an e93, but at top speeds the weight has less in it I think.

put it this way the MAJORITY of 335 drivers in the Uk forums run the D...

Diesel hype in Europe has gotten way out of hand. BMW's 3.0 TT diesel is a very good engine in a SUV or a larger family sedan - for towing, cruising, carrying a larger load etc. But for enthusiastic driver who buys a 3-series BMW there is no substitute for 3.0 TT gasoline engine. 3litre TT diesel is a very good engine for cruising, but not when you are trying to have fun/when pushing your car. That is so because of the huge differences in powerbands - gasoline TT engine has max torque from 1300 to 5000rpm. And engine revs freely to 7000rpm and has significant amount of power and torque in the high end. So basically from 1300-7000 is the usable powerband and you have the feeling of a free breathing, high revving egine whith a sporting character. Diesel TT engine has max torque between 1750-2250rpm. After 3000rpm its starts to loose power and at approx 3500-4000rpm you get the feeling that something is choking the engine and tach needle is sort of starting to hit the wall. Its like driving a powerful truck engine. The limited and very low powerband takes all the sportiness away from the car.

There is no point of having the diesel when the gasoline engine has the low-end torque charateristics of a diesel. 335i even reaches max torque 450rpm earlier than 335d. That combined with a rev limiter as high as the E36 M3 S52 engine had is a small miracle itself. This is the combination of characteristics that no diesel to this day is not even close to achieving.

[Serjames]

....umm, so you HAVE driven one right ?



SJ

[Brock Landers]

Ofcourse! What you think I just made all this up? Drive them both 335i and 335d back to back and you will understand what I'm saying

[Serjames]

well i had a different experience...

For an everyday highway basher I think the D is a better car

For out and out driving ability then yes, the i will always win.

But the d is good really good - don't confuse this with your everyday oil burner !

i would be interested in the 335d if turned high 30's to mid 40's average mpg, any less than that and I'll keep my regular 335.

I think when many people hear diesel they think of big rig trucks so thats probably where the "horrible smell, poor performance" ideas come from. I've actually heard from many europeans that this type of diesel in audi's and bmw's burns cleaner than regular pump gas, helps engine provide much more power, and is much more fuel efficient. I once thought the same way many people here think about diesel, it wasn't up until I spoke to a few real users that my eyes opened up

Well said. The n35d register-turbo BMW's can rev a little higher than other diesel engines. BTW, what we see on some HPFP's in the US is nothing compared to what you see on the common rail diesel pumps. They provide much more pressure as the HPFP and fail relatively often.

With EPA estimates of 23 city / 33 highway, that's only about 3 mpg better than the 335i.

But for that 3 mpg, you'll probably pay $2K+ more, and have a car that's much slower to boot.
Have only selected gas stations to fill up at, and currently in many places diesel is now more expensive than premium gas (remember the days when diesel was 20-30 cents LESS than REGULAR Unleaded??? Yeah when asked a couple years ago why diesel has shot up in price compared to unleaded gasoline, an oil industry insider said, "because we can" obviously to line the pockets of the oil industry even more in preparations for more diesel engines being made and coming to the states).

To top it off, you have a car that's not as smooth or quiet either.

I love the idea of a diesel if/when it provides advantages over an existing model (like say if it came out when BMW only carried the 330i)

But I just don't see too many people paying more for this car over the 335i just to gain 3 mpg but lose in performance, quiet-ness, smoothness, fuel availability, etc.

I think it makes more sense in the X5 for towing and gas mileage in that category.

Very WRONG regarding the milage!

I know for sure the real life savings would be 35%.

But I agree regarding smoothness!

You would be surpriced! The 335d use a lot less than 335i real life.

You have never driven a 335D, thats for sure

The real thruth is that talking about usable power the diesel beats the gasoline car by far. If you compare the horsepower between the most used register, 1500-3500 rpm the power looks like this: (measured in the same dyno, rear wheel hub horsepower)

335i 335d
1500 92 115
2000 109 156
2500 136 190
3000 163 231
3500 194 260

And that diesel runs freely and hard to 5000 rpm, max hp at 4150.
But the 335i is faster when both cars are revved hard

But the diesel will be faster in many traffic situations, and use 35% less fuel.

The low-end HP of the 335d is great, but unfortunately when you factor in the tall gearing that's needed to compensate for the low redline and limited power band, most of the low-end torque advantage vanishes. Not only is the gearing higher, but you are shifting into the next gear sooner as well. This really kills the acceleration of the diesel compared to the gas engine. But in gear acceleration of the 335d at certain engine speeds is certainly good, but this is only for a very narrow rpm range. I think with the great gas mileage, it still does make sense for many to get the diesel, despite it being slightly slower.

[stressdoc]

Daily driver & highway cruiser, 335d is much better.
Sports driving in twisties/canyons, 335i is more fun.
Steptronic, 335d is better.
Manual tranny and high rpm driving, 335i is better.
Fuel mileage, real life, around town the 335i range 13 - 18 mpg, highway 24 - 30 mpg.
The 335d is about a third better, around town 18 - 24, highway 32 - 40 mpg.

The 320d gives almost double 335i fuel mileage. About 28 city, 45 highway.

I really hope that this works for BMW, there is a lot of ignorance to overcome, as demonstrated by some of the ill-informed comments in this thread (stinky, noisy, not fun, ...). Fuel consumption is a really important issue for our nation.

In the best of all possible garages, I would have a space efficient (small, lightweight van/touring) BMW diesel, and a Z2 M 4cyl turbo.

This is the 335d test drive, pluse the 335d was in last months Roundel.

No 6MT in the Diesel is what I've heard

Im out

[grkm3]

um you guys know you can boost the D to over 20psi right?This car will make 600ftlb when modded,that is one of the perks of having a D engine.

here is a vid of a stock 335dt racing some cars(all having way more hp than it)off the line it beats them all pretty bad

Might just be me, but manual shifting in a diesel isn't as much fun. It does not have the same need for precision that a peaky petrol engine does. Diesels honk pretty much whatever gear you are in, they have such tremendous mid rpm torque. A steptronic is really well suited to the diesels. I might want a manual on the 4 cyl diesel, mainly to max out the fuel efficiency, but the 335d will be well matched with a step..

[silvrevo]

CANT you run veggi oil in desiels also with some extra work......

I would like to see a "Tooned "4.4 v-8 twin turbo thou.

Anyone have the weight specs on the up coming v-8 twin turbo?
