We talk about unit cost itself, 1L Turbo 3-cylinder engine vs 1.5L 4-cylinder Natural aspiration engine which one cost the manufacturing more?

Got songlap or not?
Fake emissions?

1.5 more than 1.0
4-cylinder more than 3-cylinder

so 1.5 4-cylinder cost more to build

cost base on what?

the R&D not count in the total cost ?

but but but tebo engine has more component worrr

Tebu + ICE > ICE

You need to built engine and turbocharger vs built 1 single engine.

Quiz: What does a 1.5L engine aspire?

Answer: 2.0L

How much RnD can cost to affect production cost?

Turbo engine cost more.

More parts = higher cost.

Also, some turbo engine have stronger materials. This will also increase cost.

Avoid small turbo engines. Pure designed for emission only. If mod, confirm sure kaput.

scrap metal price, which weight more?

2.0L Turbo that's the real thing

RnD cost does not affect production cost.

RnD cost + production cost = total cost

Those are calculate as 1 project. The cost of engine will calculate base on that project.

what kind of comparison is this.
1litre engine and 1litre turbo engine = same engine.
obviously 4cyclinder cost more to build than 3.

turbo wise is depend on what size of turbo you put, type of exhaust manifold, intake manifold, piping, intercooler, ecu, and few more hoses + mounting point.

so whats the point you want to know?

Btw read an article some time back, EU is reversing the downsizing of Turbo engines trend since the new emission guidelines. With the revision, apparently the smallest practical turbo with consideration for emission would be 1.6L.

A lot similar question like why ITX mobo expensive than micro atx/atx since it use less component.

Why err?

less 1 piston, piston ring, exahsut hole, sparkplug, ignition coil, 2 valve, shorter rod, just add 1 siput at exausht u cost effective la

plus supercharge, hybrid, solar.

Is toyota will built a 1L turbocharged engine, be interesting, which sedan or compact will base on this mill? Already in my shopping list to get a "car" category of vehicles.
