Ignore the fact I was browsing the Smart website for one moment and explain to me what a "naturally aspirated turbo" engine is when it's a home.

Naturally Aspirated turbo, usually means it's got a carburettor not fuel injection. I'm shocked that a modern car would use a carb as I wouldn't think the emissions would be low enough to pass any kind of test these days.

Renault used to run cars with carbs and turbos in the 70's & 80's.

Everyone used to run carbs in the 70s and 80s.

It's likely a mistake on the Smart website.

Really?

I'd guess more that some has cocked up with the wording on the website.

Never heard that definition before.

In engineering terms you've either got "naturally aspirated" or "forced induction" and referring to the charge entering the inlet tract to the combustion chamber, the method of fuel introduction (carb or injection) has nothing to do with this. Thus a turbocharged carb car would be termed "forced induction" and not anything else.

But in the Smart bumph above, it could be new term invented my the marketing people, or, as noted above, some muppet putting words on a web site when he no knowledge of what he is writing.

If it were on a technical site, I would have said that it was the turbo spec engine and system, but without the turbocharger fitted. But it isn't, and basically the copy writer got carried away with technical words that they don't understand.

I know exactly what it is, it's an Error model, nothing but trouble best avoided.

The problem occurs via the data Inputter interface with the computer, normally fixed by a sharp tap with a hammer, or if persistent replace the data Inputter. wink

Only if wearing gloves, & protective clothing as the Inputter has a tendency to leak fluid for a short time after being struck. weepinghurl

I think the description is correct.

I gather the spec also includes overhead side valves, round D ports, full skirt slipper pistons and a dog-box automatic gearbox. I think it has drum brakes with radial calipers too.

Simple - the turbo's intake is naturally aspirated. If it was sequential twin turbo, then it would be a turbo turbo.

Of course, the first turbo in line is naturally aspirated and the second one is FI. Now, if you're got a sequential triple turbo, the later two are FI and...

Basically the first turbo is always naturally aspirated.


It's a fact.

It's their way of differentiating between Petrol & Hybrid models whilst making themselves look silly to anyone who has a modicum of knowledge about cars wink
