Petrol vs Diesel?

Featured Replies

good post Mr Awol.

the primary difference I find is that in order to drive a petrol quickly, you have to rev it, and you then get close to single figure mpg.

in a diesel, you don't lose so much mpg driving quickly.

besides, 70mph is 70mph is both cars............ ;)

  • Youre more or less bang on with your assumptions. The petrol is certainly outrightly a bit faster and maybe a little less nose heavy; more fun I suppose. The diesel counters some of this by being on

  • This is probably the best thread I've read on Briskoda so far for it's unbiased postings on the vRs petrol/deisel subject. I think it's reasonable to say neither option is perfect, both have their adv

  • No it wouldn't................the petrol would have to stop for fuel nearly twice as often

I have run both the petrol Vrs and diesel back to back and as a police advanced driver I will make comment on handling as well but it is a personal view.

I purchased a new Vrs Petrol estate (divorce present to myself)in May 2011 and ran it for 12 months but due to a change in the location I work my mileage went from 15k to 25k per year.

Petrol- I do the majority of my driving on a motorway to get to work and running on Shell Vpower I averaged 35MPG. The car was a bit quieter than the diesel and felt crisper on acceleration from standstill and did not under steer as quickly as the diesel. Brakes felt more responsive (but that could be car to car differences).

Diesel- The car is now 9 months old and has just been in for its 20K service. It has averaged 50MPG over that time. In gear acceleration feels more urgent, probably thanks to the extra torque but that's about it.

Unless you are on a track day 2 drivers of equal ability driving a petrol or diesel would be unable to pull away from the other car. The big differences are in power delivery and cost of running the car. The petrol car will depreciate faster, while the diesel may cost a bit more to service.

At the end of the day a CR is very close to a petrol on performance on paper and in point to point it would be impossible to separate them so it come down to economics, mileage driven.

For the record I miss my petrol car.

LMAO your end comment "for the record i miss my petrol car"

And there we have it!

I'm sorry you cant compare a diseasel to a petrol

so 70% is nearly twice as often is a trouncing then!

Argument settled! :)

Disagree about it being impossible to separate them point to point, there wouldn't be a huge amount in it though. I went from a tfsi to a CR and as soon as I drove the CR I knew it wasn't as quick and was disappointed. I went from CR to tsi and the tsi just felt quicker. Point to point I know which one I would get there first in and I know which I'd have more fun in in the process. It's all down to personal choice in the end

When you come to part with your VRS you may find with a petrol the dealers simply aren't interested in it. This is despite them going for reasonable prices in the classifieds. Diesels the dealers will bite your hand off for.

I drove both before buying and there is surprisingly little in it on a normal road.

My TFSI will get 35mpg at 70mph

My commute is mostly at 60 so I can regularly see 37

Long term average is 34 (winter drop)

If you drive with a heavy foot 26mpg is more likely.

I do 12k a year. I did my maths before buying and there was nothing between the two cars over 3yr. I've had the VRS nearly 6 years now and it's done nothing to make me regret my choice.

However with hindsight, I'd have bought a Scout. Their residuals are nuts.

I suppose the sweet point is when you put a stage 1 remap on a cr. then you will get very similar/ same performance as petrol but still maintain improved mpg. Best of both worlds then.

Great objective view of both cars and given your credentials and that youve had both cars this is the post to be listening to.

I laugh at the competiveness of some people on Briskoda and how these types of topics inevitably become a cockfight over which vRS variant is better.

Honestly I think both cars are great and clearly have their up and down sides. The diesel will never be quite as fun as the petrol to drive as its always going to be less electric to drive because of the very nature of what it is..a diesel...its more sterile and also it gives away 30hp to the petrol so no one is ever going to argue the toss which one is more fun or quicker.

However my personal feeling on the diesel is that it is actually quicker than it feels and its performance is very subtle and deceptive...when I give mine a punch I often think "oh...is that it?" to then look at the speedo and realise very quickly if I dont slow down ill be in trouble.

If I hadnt got a Blackline and hadnt been looking to reduce fuel spend then id have no doubt favoured the TSi but that said I think youve either got to be a commited petrolhead or hate diesels to buy a TSi that frankly has the thirst of a six cylinder car if driven as nature intended. I know it would depress me to be running a family car that struggled to average much more than 30mpg on a long run......thats exactly why I got shot of the Fabia in the end.

So to sum up IMO the TSi is the better performer and cheaper to buy both new and second hand but it is very thirsty and anyone saying that its not is a bit deluded frankly.

The diesel isnt as fast but its a 140mph car that can still return 40ish MPG pretty much however its driven and I guess to a great many people in the market for a good value high performance Family Car that matters more than a 1.2 second faster 0 to 60 time and a 9mph higher top speed.

Do I miss my little Fabia rocketship...yes of course I do but do I regret replacing it with a diesel car thats way more frugal and not a great deal slower...not at all.

If buying a 3 year old used VRS then petrol for me every time

The CR TDI may come to bite you on the bum with that DPF if it fails and it costs a few bob!

Or the chain tensioner could bit you on the bum even harder on the TSI!

Just driven from my home to Haverfordwest mostly M4 and D/C. Cruise set at 70, but full throttle out of RABs with a road bike on my roof. 37.1 average, and on squishy winter tyres. Allegedly the engine has more power than std.

Yeah that is actually a fair shout. If a DPF happens to fail which really is not v common on a CR engine until its done alot of miles it can be removed for a few hundred notes...chain tensioner failure which is a known issue with the TSi's would be new engine territory

Thats about the book figure for a TSi isnt it; not so bad considering the winter tyres and the bike

The winter tyres are 2-3 Mpg worse so I'm more than pleased. If i want to save some cash then I know it's possible, but then almost all of my mileage is business and therefore paid.

I think that from now on diesel drivers will have to look at DPF and DMF in the same way we all look at brake pads and tyres. Just another consumable. None of these cars from any manufacturer are designed to last that long. They are white goods and they all expect you to regularly change.

at least us vag owners dont have to worry about changing the oil in the dpf unlike owners of fords. The oil + labour costs a fortune AND if they clog up like ours they still need replacing

Talk to a guy recently who had a Peugeot hdi 406 or 407. , and he mentioned that he had a service which included some oil either in his dpf, or cat, not sure which but it apparently cost him £750 to have the unit filled..

im pretty sure thats because the pug hdi and ford tdci are pretty much the same engine

They are exactly the same. The HDI engines are all ford units these days......the 1.6 HDI in particular is used be everyone and their dog: Suzuki, Mini, Citroen, Ford, Peugeot, Mazda and Volvo.

A mate has a 307/308 hdi and apparently they have a tank under the boot which needs filling with a DPF liquid which is then added to the diesel in suitable quantities automatically and is used too get the exhaust hot enough for a regen. The liquid is apparently very expensive.

Is that liquid Adblue?

Cos it's cheap as wee wee (it's a urea solution).

Last time I bought adblue, it was about £18 for 25 ltrs. If this is the stuff that's going in what a mark up.

Just to add my little piece - I've owned a pd vRS and currently drive a tsi vRS. Both were initially standard and both were remapped. In my mind its really simple, the petrol is clearly nicer to drive, smoother, more refined and more fun. The diesel was very good, but felt slightly diluted, however mpg was better. Handling wise they both felt very similar until I began modding the tsi.

IMO, under 12-14k petrol, over that, diesel. Simples!
