Cos its too awesome for the ground

Most drivers rarely exceed 2500RPM

Most drivers don't like shifting gear too often

Most drivers prefer fuel economy over performance

For all those drivers, there's modern diesels

For the rest of us, there's performance petrols :pac:

In fairness Squall does make some decent ish points, however no one can deny that acceleration is caused by torque The ole graphs Squall have lashed up are about as useful as gorgeous t1ties on George Hamilton though as the lashings of torque shown are not the torque figures at the wheels, they are the engine torque, which diesels have loads and loads of.

As various folks have mentioned in here the gearing plays a huge part, diesels generally have long gearing, the jap quick off the mark petrol yokes have short gearing so the torque at the wheels for them is decent, obviously they have decent torque at the wheels at low speeds as you can spin wheels no bother from standstill.

The gearing and the torque at the wheels at a given speed determines acceleration, the torque of the engine obviously plays a huge factor, in top gear in a diesel at low ish revs 'twill pull away nicely without the need to drop a gear as the ooooodles of engine torque compensates for the long gear and away she goes.

I dunno could graphs be gotten of available torque at the wheels going through the gears in a diesel like a 535d to show where the sweetspot is in each gear, would be interesting to have a look at that against a similar plot for an M5 or something. 'twould explain rather well how the 535d marlow mentioned is a match for the M5s on the track.


^^^^^^^^^^^^ don't be picking holes in that shtuff now gents, 'tis a public holiday :pac:

Not exactly what you are looking for but there is a dyno print of a 535d in the dyno thread

Your 525D is nearly as fast as your M5:D

If you'd read, what I wrote, it would help. I said NOTHING about my 525d being as fast, as my M5. I wrote, it is as QUICK as the M5, when it comes to overtaking and from a standing start in everyday life.

That's a vast difference.

I think your the one that doesn't know how to drive:p

Lets compare.

Overtaking a diesels fortay.

530d here as no figures for a mapped 525d

An M5 will do 80-120kmh in 3 secs, a 530d with 218bhp will do it in 5.7 secs

An M5 will do 80-180kmh in 9.5 secs, a 530d with 218bhp will do it in 19.6 sec

You're quoting E60 figures. The E60 M5 is a completely different car to the E39 M5. I was very specific on which cars I compared. Please don't just throw the stuff together gobbled as it suits yourself. You're prooving nothing with that.

Obviously you're just grabbing random values from random places. No real personal experience. So continue to live in your dream world and I'll go and spend some time in the real world instead.

Can someone remind me why people are practically orgasming over an Octavia?

Really good marketing on VAGs behalf. People are attracted to their core values, utility and value, their main competitor is the Korean manufacturers and badge conscious buyers are going for the entry level VAG Skoda in their droves. The "diesel is better and faster" myth is alive and well... all pub talk though.
