0-60 is an easy arbitrary figure. Unless they set a specific gear then a specific speed range, in gear times will always be hard to judge against other cars.

I reckon the 1/4 miles time is the best indicator overall.

regarding 0-60....its just one of the "mechanical performance" criterias that is used as basis for a measure of comparison....(I don't know what the fcuk, I'm talkin about....)

anyways....its just to see whos got the biggest dick at the end of the day!...

Different measures mean different things to different people.

I find 0-60 times quite interesting on the basis that it tends to provide a good indication of how the car will perform when you are 'on it' on country lanes.

Obviously in gear is more helpful to understand how the car performs under more 'relaxed' conditions. Which is probably more representative of most driving situations.

0-60 is about horsepower and in gear is about torque so it's an interesting comparable for diesel and petrol.

What stands out on the 335i compared to the 330i is all the extra torque for those in gear times. It's almost like a cross between the 330i's rev-hungry nature and the 330d's mid range shove.

Quelle horreur Kevin, you don't say ............that's me buggered then lol and I reckon if it's a case of zip, lob, thwack it on the table, then Mr Hoops has it licked...............I bet he can't touch the end of his nose with his tongue though. Only kidding Stephen but I know how endeared you are to my references to 'willy waving'.

Sorry, a totally O/T moment there.

Hey everybody,

I'm not a BMW owner yet but am looking at a 335d for a daily car.

I've got a weekend toy which is a Toyota Aristo V300 (2nd Gen) - for those of you not familiar with japanese imports, it's basically a Lexus GS300 with the same 3L Twin Turbo found in the Toyota Supra. With similar mods as most 335i's out there (decatted exhaust, air filter, intercooler, dual boost controllers, fully braced body, etc) I've managed to keep up really well with E55 AMG's with an exhaust, walked a handful of 335i's (one tuned), E46 s/c M3, Porsche C4S, etc and also have had my a**e handed to me by a number of cars. So I hope that gives what I say below some credibility.

1/4 mile times do not really measure anything other than how quickly 1/4 miles worth of ground is covered. Most of this is down to grip, launch technique and more importantly driver skill in achieving the lowest possible 60ft. A lower 60ft directly translates into a lower 1/4 mile time.

The TRUE measure of a cars power is the trap speed. You can have a 600bhp car that can run a 1/4 mile time of 12 seconds but trap 125mph+ yet at the same time you can have a 400bhp car that can run a 1/4 mile time of high 10's but trap 118mph. What this would mean is the 600bhp car has less traction off the line, which can be attributed to a number of things such as tyres, improper launch, improper alignment, too stiff suspension, etc. Where the 400bhp car could be on drag radials, with geometry sorted out, softer suspension (allowing the car to squat to maximise grip), etc.

BHP figures again cannot be directly compared - I've run against a 430bhp (flywheel) Supra Twin Turbo and kept even whilst when up against a 480bhp+ E55 AMG I was inching away slightly (1/4 car length from a roll lasting 60mph) all done on private roads of course .

Just had to say all this as I think there's too much emphasize placed on 1/4 mile times to measure power on these boards than the trap speeds.

EDIT: Further to the above...in-gear acceleration is again a big thing in the real world. Most of the run in's I've had with other cars have involved roll runs where in-gear acceleration matters more. This also helps in overtaking and a number of other situations. 0-60mph doesn't tell you much other than give you bragging rights in a pub with all your mates.

Here's a question for you all - who drives from a standstill to 60mph with their foot to the floor? and more importantly how often?

More important is the time it takes a car to get from 30-50mph, 40-70mph, 50-70mph, 50-90mph, etc as those are the speeds you would normally be doing when overtaking or getting up to speed on motorways. A time for 60-130mph would be more indicative of not just low end grunt but top end power as well.

Hope that's of some useful reading for some of you and helps clear up how both cars are most likely marketed and drive in the real world.

I guess I'm ideally placed to comment having had a 335d tuned and now going down the full works route in an x35i (135i in my case)

I think the D was superb, but I missed both the noise and manual box that the petrol offers.

Oddly enough, now I have the 135i, I often fail to fully utilise the rev range (probably a credit to the relatively strong low down torque which reminds me of the D and so my driving style has not fundamentally changed) but I do still appreciate the noise and superb versatility of the engine in the petrol car.

I don't doubt the 135i will end up quicker... But for now the D is a quicker all round car (tuned) than the stock 135i.

Me. At least twice a day

but hes made some good comments...

yep, as loads of other people have said on other forums....an important benchmark is 50-100 time....I do tend to agree aswell....that this will reflect a "real" fast road driving performance measure....

very hard to compare cars, even though they have similar bhp figures, we have to consider factors such as torque and where in the rev range is the most power being generated...

this might explain why Ed's 335D will leave 2 cars length distance with my 335i when coming out of a roundabout on a slight uphill gradient up to 50 until I finally caught up... (assuming we both floored it at the same time.....)

The reality is, that the 335d is more likely to be in the optimum gear, but you will be in third. Screaming around at 50mph in second is fun, but you don't do it all the time on the road.

In a 330i, you would be forced to snatch that lower gear, but the 335i has enough torque so that you just don't bother.

Another thing that comes into it is gearing in addition to how soon the torque comes on, where peak power is, how flat the torque curve is, how much power under the curve, etc. This all adds up to driveability and dictates what kind of a car it is. Figures are just that - figures - they mean bugger all in the real world.
