Factory Diesel Jimny

Engine technology and reliablility has changed massively over the years, those who are 'of a certain age' will probably remember the VW '100,000 mile club', these days we think nothing of 100,000 miles. We should have had engines more like the Ecoboost engines a few years back but the manufacturers were still pushing (at a premium) diesel technology.

The eco boosts are only economical in the offical cycle tests ........suprise suprise

In real life use they are a lot thirstier (according magazine tests)

I guess its beacuse its a small engine with a turbo and turbos are always thirsty once they spool up

Exactly, their designed around passing the low emissions tests whilst still being powerful enough to keep up with a traditionally bigger more thirsty engine. So at the low revs needed for the minimum emissions test they use hardly any fuel and look great but when driven hard they end up using more fuel that the bigger engine or at least way more than advertised. I thik the technology is pretty good and interesting but it is geared to make the most of the rolling road test rather than real worl economy and power delivery.

A lot thirstier is a bit of an exaggeration.
Our Focus 1.6 Ecoboost 150 hbp is 16.9 km/l, real life consumption is more around 14.5 km/l. I know it is not like the official numbers but still acceptable if you ask me.

My Buddy's 1.0 125 bhp Fiesta is rated at 23.3 km/l. Real life consumption is around 18km/l, which is also acceptable in my world.

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
