T5 Hybrid Longevity?

[mercuryrev]

Having had an XC60 in the past, we are now thinking of returning to the fold and are looking at an XC40 and a hybrid in particular.

All our recent cars have been diesels and I'm wondering how well a 3 cylinder 1500cc petrol engine will last with higher mileages.

Or is the point of this particular model, that you shouldn't be making long distance trips?

Has anyone built up any serious miles with this engine yet?

The 3-cyclinder 1500c engine has been fitted to the T3 without any hybrid tech. There's no reason whatsoever to suspect it might last any less longer than Volvo's 4-cylinder engines.

Thanks for the reply, my suspicion is not based on anything that I have read but not being sure how long these engines have been in existence, it made me wonder if anyone has done big miles with one.

I have been caught before with a huge cost to replace a DPF on a supposedly reliable VW after 75-80k. Equally I have bought, or driven, diesels since I can''t remember when, so spending a lot of money on a 3 cylinder petrol engine producing 180bhp makes me a little nervous.

After my VW experience I don't have much faith in a manufacturer admitting they have sold me a vehicle that wasn't fit for purpose.

In the old days (a couple of years ago) I would automatically just go for a 2 litre diesel for it's power, torque and ability to soak up the miles. Maybe I'm just being an old f*rt....

It IS the familiar volvo 2.0 vea engine we have had for the last 7 years , just one cylinder missing . up to 180 bhp from it too .

Well there we are, I knew I should have googled the exact engine before replying...

Speaking as an engine builder of over 4 decades experience...

As a general rule of thumb, smaller capacity engines are, like for like, more robust. The simple physics is that s smaller, lighter piston and recipricating assembly "weighs" less at the top of the stroke than a large, heavier one. In simple terms this means thinks are less likely to break,

Now I say like for like, as along with less inertial stresses to accommodate designers will use lighter blocks, cranks, crank journals, etc, but the point holds true that a smaller capacity motor is no more inherently liable to have a shorter life than a large one. Unless Volvo have dropped a major clanger and designed in some kind of fault it should be competitive with any other well designed unit.

Neither being small capacity, a triple, or having a high specific output, make an engine automativally or inherently less durable, the same way being huge, multi cylinder and a lazy, output does not make engines inherently more reliable. Transmissions that handle that power are a different matter entirely...

The only people that reckon VW are reliable are VW. If you dig down and look at sources such as the Warranty Direct Reliabilty Index (which measure actual breakdows, and not simply customers impressions and opinions) you'll see they're nothing special, and some of their models actually perform quite poorly compared to rival products.
