Puretech petrol engines - opinions?

[Richard_C]

I am in an ongoing'think' about what to with my 3 cars for the future - 3 into 2, if so which 2, change them all.... and I'm thinking about a switch to petrol for at least one of them as the world seems to be getting anti diesel. Paris and London talking about bans, what next I wonder.

I once had a 2.9 Granada with a Cologne V6, huge chunk of iron churning out 150bhp and 170 ft lbs of torque. Now I see the new citroen puretech 1.2 3 cylinder with almost as much power, more torque and it fits in your pocket (almost). I remember when the magic Japanese motorcycles arrived in the late 60's, so much power from such small engines but they were virtually undriveable because of a narrow power band.

What are these new PSA petrol engines like to live with long term - or indeed any recent Citroen petrol engines - any thoughts?

I can't comment on the Pug/Citroen engines but I've drove a Fiat Panda with the twin air two cylinder engine and that was awful, I also test drove a Dacia Sandero stepway with the 900cc 3cylinder turbo Renault engine and absolutely loved it. I'm seriously considering petrol myself too so will keep an eye on people's views of the puretech engines.

I have a DS3 DSport + 120 Blue with the start/stop, it's ZERO VED and as such is permitted in London after the ban because its a Euro 6 compliant engine. I love mine but I've only had it a couple of months. Economy wise, If I stick the cruise control on the going along the motorway at 60mph I can get 72mpg out of it. I'm averaging 58mpg without thinking about it.

The wife drives a VW Polo 1.2 FSi Bluemotion and she loves her's but again she's only had it a couple of months, I haven't got round to doing the same test with Polo, as per above, it's on my 'roundtuit' list.......

Am i the only one thinking, small capacity & big power = bang at some point? Didn't vw have loads of issues with their 1.4tfsi engine going pop regularly?

I'm of the opinion that there is no substitute for cubic inches. So says him who is running a 1.4 derv [emoji48] [emoji3]

I love the way you blokes talk about a "big" three litre V6.

To me, a big engine is still something over five litres. Over three and a half but under five I consider "large", but not big.

Clickbait

Love the way you think "Big" is a definite : Big depends on what it is attached too......eg a 3.5ltr V6 is big in a lightweight Lotus, not all of us need 3.5 tonnes of metal and live 450km away from MacDonald's , they just do not fit in the space over here.

As they say, Revs are cheap, Torque is cheap, but revs and torque ? don't ask just get a V6.

[RichardW]

Big enough?

Did the Alloytec V6s get used in anything there? GM's first attempt at a sophistamacated quad cam, VVT V6. Three timing chains, up to four cam variators and heads that ran far hotter than their redneck owners truly understood, baking neglected engine oil into an obstructive sludge (sound like the 1.6 HDi?)...

The little I've read on the VAG 1.4 suggests its early and admitted faults have largely been engineered out. They deserve a little credit for that. Have surfed through the HJ reports on their PureTech 308 and it sounds "worth keeping an eye on".

That you cannot stall up a modern driveline, annoys me.

The quality of robotic engine building is the key to the small high rev engine, all you need is a variable speed gearbox to make them comfortable for long runs.....oh no that's a DAF(t) idea

I have driven a couple of 1.2 3 cyl pas machines, and have to say the performance is remarkable for the engine size . They rev like a petrol & have the torque of a diesel . How they shape up long term remains to be seen .
I know a guy in another garage, who is getting loads of transit connect cam belt failures. The psa triple has an oil bathed cambelt, the transits are breaking at 100 k miles

The few small capacity high power cars I've been in need revs to go. I don't like such frenetic driving and prefer a relaxed style.

Then town is not your normal environment driving then

72% of car "journeys" are less than 5 miles ? that would not even warm the lower rad on a 2ltr oiler let alone the cat/dpf

[demag]

I drive in town yes. Well not so much drive as wait in long queues.

These 3 cyl engines don't need to be revved to get power from them.
You really should drive one, sure you will be pleasantly surprised.
