Peugeot's threat to diesel

[Ryeman]

We love our diesels but TBH just took delivery of a diesel substituting 308 hatch.
It's a 3 cylinder siamised wet sleeve all aluminium 1.2 DI turbo (95RON ... cheaper than diesel)
95 kW.....230nm from 1750rpm! (95% fm 1500)!
urban 6.4
combined 5.1
extra urban 4.3
its Aisin (Toyota) 6SA gearbox will torque it's way over hills in rolling country without dropping down ...like a diesel
But no DPF issues to worry about either.
There's a higher performance 1.6 'sports' version coming.
emissions have forced Peugeot to phase out its all diesel range.
scaling up you wonder whether petrol power might take over from diesel.

If this is the way of the future then let it come!

I think they make great performing engines but i don't like working on them!

Also, DPF's arent really a problem.... for every forum bad tale theres a lot that are happily motoring

Im too old and intimidated with the latest tech to tackle any modern car now and certainly during the warranty period, even for a fiddle.
With fixed price servicing just maintaining the levels for me now.

Unfortunately no MK7 TDI bluemotion for us, but look at its stats:

The Volkswagen Golf TDI BlueMotion features a new 1.6-litre direct injection four-cylinder turbo-diesel engine that produces 81kW of power between 3200-4000rpm and 250Nm of torque from 1500-3000rpm

and 3.2l/100km extra-urban. All the new euro hatches are economical for sure, but theres actually a huge difference between 4.3l/100km and 3.2l/100km..... the pugs using 34% more fuel - even if, for now, thats not too meaningful for your wallet.

I've found that petrol engined cars almost always exceed their stated consumption while diesels will often better them.

The fuel cycle tests somehow seem slanted towards making things easier for petrol engines (or making it tougher for diesels).

[Greg Roles]

It is indeed a pleasing trend, and is pushing the boundaries of hp per litre, which is awesome for technology. I look forward to less and less Dodge Rams on the road with one little bloke in them. I understand why particulates specifically make diesels a tougher and tougher choice for manufacturers, but one key thing for me: throw a tune on a highly strung petrol and you will get mild gains. Throw a tune on a diesel and you've got 100nm plus.

DPF design is now so advanced, a lot of the MKV era problems are a thing of the past, hell I can't even physically detect the DPF regens in my Yeti, and it will take an EGT reading to know. On the MK7 the DPF setup is really getting clever, but sadly the lower SiC closed cell filter will eventually clog.

A 308 six speed manual recently set some sort of record at Almeria, Spain, doing 1810km on 51.4L (2.85L/100km).
its a much lighter engine and uses cheaper fuel.
Our old Jazz auto wouldn't lug up our shallow sloping driveway in reverse without using the throttle whereas this (auto) behaves exactly the same way as the diesel Yeti, like a tractor but without the noise.
i simply can't believe a small triple can behave this way, particularly the level of torque at such low revs.

But consider how many ks you'd have to travel to get back the Diesel engine option price premium.
assuming for simplicity 3 v 4 L/100km
diesel cost 130c/L results in 390c/100km
95RON cost 115c/L results in 460c/100km
= 70c/100km more for 95RON
NOW
Diesel engine option $1000
repayment distance ~ 145,000 km plus extra servicing charge for diesel in my experience.
Plus extra weight noise and pollutants
and I own a diesel.

But you're assuming you don't get any of that premium back when you sell / trade?.. I also agree with what kaanage said - diesels in my experience can actually achieve their stated fuel economy easily.. Petrols not so much..

That's a very valid point. The petrol engine's fuel economy is valid on the paper and hardly ever on the road in the real life driving and it was always like that for a decades. The Honda comes very close in their advertised fuel consumptions, the others are just a good liars. Just load the petrol car a bit, drive in the city or on highway in 110km/h and the fuel economy is far from the stated. Where the diesel will almost always be better than specified, especially on the Euro cars/vans.

Another thing is driving enjoyment. I much prefer the way a petrol turbo drives and revs in comparisons.

Also don't forget to factor in how much cheaper petrol is and also cheaper insurance.

Small or medium car- petrol.

SUV or 4WD- go the diesel.

[Ryeman]

If the 1.6 version was available in a Yeti style vehicle I'd be hard pressed to justify the added weight, costs and emission issues a diesel now faces.
remember this 3pot doesn't rev to perform.
it has such a diesel-like driving character which in my 70 years goes against all my previous experience of small capacity petrol engines.
My Yeti will chug up my driveway just like you would expect a diesel, the traded NA Jazz wouldn't without prodding the throttle but the Pug at idle rips up the drive even faster than the diesel .....must be a v tight converter.

[Ryeman]

RTFM....it's programmed that way for parking.

[gldgti]

Personally, regardless of any of the cost factors, using 3l/100km as opposed to 4l/100km to me is very attractive. I'm not so concerned with the fuel cost/saving as I am with the fact thats its actually using less of it.

Some of us care about these things yaknow?
