It’s a Fiat 500. Not the sort of car that normally gets us excited. But like so many things in life, it’s what’s inside that counts. In this case, because it has the Italian firm’s new 900cc single turbo two-cylinder engine under its retro bonnet.
Fiat 500 TwinAir Technical highlights?
The engine, obviously. Fiat calls its new TwinAir unit its ‘manifesto for its latest engine tech’. So as well as being physically downsized, the all-new unit has been designed to make the most of Fiat’s MultiAir system.
It uses electro-hydraulic control of the inlet valves, rather than a conventional camshaft, to manage the amount of air entering the engine. This allows more precise management of combustion, reducing fuel consumption.
As well as boosting efficiency, the managed air flow improves low-down torque, while the more constant flow of air keeps the small turbocharger spinning, pushing power up to 84bhp, and just under the magic 100bhp-per-litre mark. Not bad for such a small, yet refined engine.
