Looking at getting a new car but not sure what engine is best to get ( petrol or diesel )

Most of the journeys are short trips 3 -5 mile. And quite frequent. Will do the odd 30-40 miler and an even rarer 100 miler. No more than 10,000 miles a year.

So what do you guys think.

It’s got to be 7 seater and the front runner is the kia carens 1.7 crdi 134 bhp

Thanks in advance

Based purely on journies – petrol.

But, the Carens is quite a lump of a car and it could be that the diesel will be nicer to drive due to the torque characteristics. Depends on what petrol engines are available for it.

A diesel will get clogged up if you only do frequent short trips.

Yeah that’s what I was thinking. They don’t do the trim pack that I want in the petrol versions so May its time to choose a different make

Fiat multiple froggy thingy?

Petrol.

Modern diesels with DPFs hate short journeys but the car salesmen won’t tell you that.

OT, but what constitutes a short journey, out of interest? If we’re talking around 10 mile trips during the week, and longer journeys at the weekend is that enough for it to stay unclogged ?

10 miles of fast motorway perhaps but around town – no.

This..

Or..

depends also what the longer journey is. If a motorway run, so you can open it up and blow the crap out of the filter, that’s better than another hour at the same sort of low engine speeds as you’ve been doing all week.

This is my excuse for thrashing my diesel whenever possible. Better for it.

I’m coming to the conclusion that a long motorway run at <2k revs is actually filling the filter more than my standard 15 mile mixed journey into/from work.

Turbo petrol is what you need.

HHHHMMM love the bikes lol but this isn’t looking promising. The fiat isn’t that a monstrosity lol? Back to the a max maybe?

2.5T SMax, perfect!

Based on your usage, petrol, you can buy a lot of petrol compared to the cost of replacing dpf’s and the initial cost of outlay on said vehicle.

Ford B-Max or C-Max with ecoboost petrol engine?

I’m just saving to replace my golf tdi with a petrol
Golf only gets 40 mpg so not that cheap and a pain to look after
Only does about 6-7 k a year
And with the price differnace in fuel I’m
Thinking a nice a6 2.0t or golf gti

Sorry disagree with the diesel only good if you do motorway journeys. On the Motorway you sit there at low revs for hours at a time which is not good. The trick is whatever driving you do is just to rev it every so often.

You don’t need to thrash a diesel to keep the DPF clean, and cruising along at relatively low revs (I.e. 70 in 6th) won’t be a problem. The ECU just needs steady driving at a reasonable load so it can manage the regeneration temperature. If the temp starts spiking due to big accels/decels then it will cancel the Regen (which is why town driving only will generally clog up a DPF). Running at higher engine speeds/loads (thrashing it…) will just give slightly more passive Regen – it will still need a steady period at low to medium load in order to do a full Regen.

Diesel Galaxy here, that gets the same sort of use.
No DPF though, but even so next one will probably be petrol.
Warms up quicker, less to (potentially) go wrong etc.

You don’t need revs, you neex higher exhaust gas temperatures, which is dependent on engine load as well as revs. As speed12 says, if your engine is hot enough then the ECU will sort itself out – it needs some time to do a regen cycle – 20-30 mins maybe.

Plus booting it around probably causes more smoke to begin with. Sitting at 100mph for a while is probably good for it, but a bad idea for other reasons 🙂
