Thats the same as my wife's 1.4 Honda Jazz which is old tech from 2009

Great comparison

An old engine that struggles to produce a bit more than 80 bhp and 119 Nm at 2800 rpm versus a modern 1.0 Turbo that produces 125 bhp and 170/200 Nm at 1400 rpm

Sorry Tom its 100bhp. Not 125 I'll admit but fast enough for Uk traffic

I agree maintenance will be important but I do fear high powered small turbo engines might be great for new owners but would you want a 10 year old one at 100k? We could be back to the expensive diesel repair cost type conversation.

Why?

The expensive diesel repair costs often has nothing to do with the turbo. It usually related to injectors/engine head or fuel injection pump.

A petrol engine in itself is far cheaper to maintain than a commonrail diesel. And a turbo is not particularly expensive. But sure the downsized turbo engines are more delicate than older designs.

Fair point. My wife has just gone diesel again with her Belingo. I did research the petrol versions because of the problems my old Kangoo had. However the fuel economy on the available petrol engines were pants in comparison, Otherwise I would have gone petrol.

We did consider a new Diacia with the 1.5 diesel or the new 900cc turbo petrol both Renault units. Didn't test drive though but the little petrol looked good on paper with diesel like fuel consumption

There's plenty of 250hp 2.0 turbos in Subarus clocking up well over 100,000 miles. That's the same state of tune as a 125hp 1.0. The Honda S2000 engine makes nearly the same hp/litre without even needing a turbo, and they are very reliable too!

It's not the same as taking a normal 1 litre engine and bolting a turbo on. Everything is designed from the ground up to handle that power output so there's no reason why it won't be very reliable. In 1986 BMW were getting 1,400hp out of a turbocharged 2.0! That was in an F1 car, and it only ran that power for qualifying, but my point is making 125hp/litre is nothing new and these engines are not highly stressed.

Its not as of manufacturers have never cocked it up, even if you'd have thought they would have properly stress tested it

The infamous BMW N47 diesel fitted to countless 5 and 3 series cars can in certain varients suffer from premature timing chain failure. German engineering?
