How far is this VW thing going to go?

genuine question:
spec me a petrol estate that does 50mpg+, capable of doing 400miles+/week and isnt completely gutless (with and without a load).

Check engine light, 20 restarts, 21st attempt no engine start based on emissions failure. With NOx sensors downstream it knows whats going on if you fill like system with just water (like the truckers do on the Gen1 systems)
you're missing the point of this thread. the fact is diesel fuel is very dirty fuel and its very hard and expensive to get them clean. there is no future for diesel

He's talking about city driving though where I doubt you'd need an estate to be doing 400miles+/week.
cheers
sorry wasn't sure if it was about cities or generally.
i dont think so. people are calling for an end to diesel but for a lot of people its clearly the best option.
Exactly.
I wonder how much pollution is really reduced by essentially halving the usable life of a huge number of cars in order to reduce their emissions?
Indeed - I don't think diesel engines are inherently more complex/harder to maintain than petrols, it's all the extra bits bolted on - turbos, DMFs, DPFs, etc. which make them so.*
Start bolting all that tech onto petrol engines, and surely you'll end up with the same effect?
It's going to be "interesting" buying a used car at the bottom end of the market (e.g. £1-2k range) in 10-15 years!

This is generally not true - it was the case perhaps 20 years ago when diesel engines were inherently simple and hardy but modern engines have a plethora of complex ancillary components to ensure they meet (or not, lollll) both emissions standards and consumers increasingly high expectations around performance, economy and refinement. As a result the potential for failure is generally higher amongst diesels and a surprising amount of taxi's are now petrol as a result.
In countries without high fuel price almost nobody drives a diesel - especially taxi drivers.

You can't honestly be serious. About 1/4 of the taxis around here are petrol now.
hybrids.

Nope, a load of old Mondeo 1.8s and Avensis petrols knocking about in Preston.
And factor in more and more cities are banning diesels full stop and you soon wont be able to go places with your diesel cars.
Before this all kicked off there were talks about banning or restricting diesels in 6 major uk cities by 2020 due to Nox. This will only speed up that process.
I saw somewhere it was going to be a £12.50 per day charge for Birmingham for example.
Any fuel savings are going to be more than wiped out.

Maybe the Qashqai is just a rubbish example of what petrol engines can do

85bhp and 73lb ft more than the Nissan and it only weighs ~150kg less yet gets the same "real world" economy...
None of which refutes my point that Greedo's claim you need to do 25K miles per year before a diesel cars saves you money is not (always) the case. I have proved my point with figures, if you want to ignore them based on nothing more than feeling go ahead.
Regardless oh how much you prefer petrol, or want to denigrate diesels (or my choice of car), it does not change the fact that diesel is a much more viable option for many drivers.
You haven't proven anything with your figures - maybe you missed my post but the "realmpg" figure for the 1.5 Diesel seems to have a sample size of 2 - hardly representative.

How about fuelly.com?
Has a larger sample size for both 1.2 petrol and 1.5 diesel Qashqai 2014. While the sample sizes aren't massive they are still figures based on actual real data.
1.2T petrol: 38.5 average MPG.
1.5T diesel: 54.3 average MPG.
Both numbers are based on averages and I accept it all depends on driving style but my point stands. Depending upon vehicle, it takes considerably less annual mileage than 25,000 before a diesel becomes more economically viable in the long run.

Yep the DPF has them swinging back the other way. The last thing you want is a dpf diesel as a taxi driver unless you are doing constant long airport runs. In the same way driving instructors have ditched the Diesel Corsas for something petrol based again.
