Will, that does make sense.

Most petrol cars will only get into their best powerband higher up, by which point they're doing 30mph+

I always look at it this way: TDI engines are like Arnie. Slow, but immense leg power. Whilst they don't pedal that fast, they can really crank it something chronic. On the other hand, 16V petrol engines take a little while to get going, but once they start spinning, you can't stop em. And by that time, Arnie's already been through his six speeds and now running out of stamina

So Xaz your saying my engine is like arnie, does it also pinch the bums on females that come within the range? I guess it also explains the smoke :P

When I first test drove VRS couple of years pack I was well disappointed as I had a Pug GTI-6 and VRS was wallowy and felt like it had no poke as I was used to caning the GTI.

Recently when my wife test drove VRS and changed up early as she is a bird I was quite scared by performance.

Hence the reason scaring petrol cars it easy as power band is in reverse but once a good 16v is on Cam you will struggle.

cant understand what all this "running out of gears etc in a diesel" i think its exaggerated, I can comfortable hit nearly 60 in second gear, no problem hitting 80 in third without power loss and beyond 100 in fourth and then fifth it keeps pullling beyond 125( have never gone any further) so why do people keep going on about running out of gears, steam etc etc?

just becasue something revs higher doesnt mean its faster, any car that revs higher will have a lower ratio gearbox, look at the type r it revs beyond 8000 rpm but you will be lucky to get beyond 60 in second gear.

I think some of them have "dieselphobia". A hate for something they don't understand!

just becasue something revs higher doesnt mean its faster,

A Formula 1 racing car revs to 18,500 rpm. You'll find that it is considerably faster than anything on a racetrack, Superbike included.

A 1.1 Hyundai Getz revs higher than my vRS - it must be quicker then. :confused:

Somebody please stop me! :popcorn:

I'm gonna get people jumping down my throat for saying this but i have beaten a Cooper S before. It was hard work and the guy was definitely quicker around roundabouts but my Furby Vrs just about hauled him in (and passed him) on a straight dual carriageway

But the million dollar question is would you have beaten him if you were driving the Cooper S too?

Definitely not, when it comes to corners i am a very poor driver no matter what i'm driving!

yes, but it is its huge BHP thats shifting it, not its revs. For whatever the design of the engine is it obviously needs to rev that high to extract its bhp.

That raises an interesting point. For identical power output, which will be quicker, a low-revving diesel or a high-revving petrol? :confused:

Chris

There will be nothing in it. If the diesel car had the same gearbox as the equivalent powered petrol car the diesel then would run out of steam but it has a longer gearbox to cope with a lower rev band.

The Golf PD150 and the Golf 1.8T (both standard at 150bhp) both have the same top speeed of 134mph, actually the diesel is quoted by VW to have 1 mph faster(135mph)

I have driven petrol cars with the same output as my own (just over 200bhp) and they are no faster than my 200bhp diesel.

Interesting indeed... Audi have unveiled it's new Sportscar racer... and it's a Diesel !!

in this day and age with the economic climate been as it is id go for diesel everytime. and having fun at the same time in a fairly quick car. yes please.

Assuming both would be turbo'd the diesel would probably have more torque low down to help it off the line.

if they have same bhp the diesel would have more torque but more weight. id go diesel as it probably would have advantage and would be costing less to thrash about (higher mpg)

if they have same bhp the diesel would have more torque but more weight.

Would it have more weight though? It wouldn't necessarily have to...just 'cos the 1.9 lump in the Fabia vRS is a weighty block doesn't mean all diesels are!

Rob.

You cant make a diesel block from aluminium.

same bhp in deisel and Petrol engines then the quicker car would be the one with the higher torque easily because when shifting the gears you would keep it in its best rev range wouldn't you ?????

also the new Golf GTI (Octy 2 vRS) petrol Engine has more torque than bhp, so acting more like a deisel

What BHP was the mini cooper?

well there you go then a result!

would aluminium cope with the high pressure and high volativity of diesel? the diesel blocks are generally heavier due to extra strengthening.

Honda can. Their 2.2 CDTi engine has an aluminium block.

Interestingly their diesel engine is less diesely than other manufacturers though

Chris

cool. learning something new everyday.

2.2cdti weighs 1519kg

2.4 vtec weighs 1400kg

2.0 vtec weighs 1398kg

so it is still 100kg heavier. so the gap is reduced slightly with aluminium engine.

same bhp in deisel and Petrol engines then the quicker car would be the one with the higher torque easily because when shifting the gears you would keep it in its best rev range wouldn't you ?????

I'd say the lighter car would win. You wouldn't need as much torque to move it. Also the more aerodynamic car would win at high speeds (also needing less torque to move it). Torque and BHP are linked. So cars with matched BHP or torque should be a similar match. Where weight isn't linked. A 1000kg 100bhp car is quicker than a 2000kg 100bhp car.

A 130bhp Saxo vs a stock vRS. That would be interesting.
