Twin-cylinder turbo engine released in Fiat’s 500, but it won’t come Down Under

IT was revealed at the Geneva motor show in March and now Fiat has fitted its new two-cylinder TwinAir engine into the diminutive 500 in Italy, but not for Australia.

Designed specifically to meet CO2 emissions limits within Europe’s carbon-based tax regime, which has so far not been replicated in Australia, Ateco says the high-tech new two-pot is too expensive to replace the 500’s entry-level engines in Australia.

They include the 51kW/102Nm 1.2-litre four-cylinder petrol engine that powers the base 500 1.2 Pop manual, which opens the Australian range at $22,990 drive-away, and the 74kW/131Nm 1.4-litre petrol four, which costs $24,990 drive-away in the 500 1.4 Pop Dualogic.

Designed by Fiat Powertrain Technologies (FPT), Italy’s newest engine combines a version of Fiat’s patented MultiAir induction system with a new downsized 875cc twin-cylinder engine in the born-again 500, the 500,000th example of which rolled off the Fiat Auto plant at Tychy in Poland in late March.

For the record, the Euro 5 emissions-compatible engine, which has slightly long-stroke (80.5 x 86.0mm bore x stroke) cylinder dimensions and comes with variable intake valve lift but not direct-injection technology, also features an ‘ECO’ mode, in which performance is restricted to 57kW and 100Nm.

That’s about the same as the 1.2, which is currently on back-order and temporarily unavailable in Australia because demand exceeds supply.

Fitted as standard with Fiat’s Start&Stop idle-stop function, the 0.9-litre turbo-twin 500 offers claimed 0-100km/h acceleration in 11.0 seconds and top speed of 173km/h.

Fiat says that, as a manual, the 500 TwinAir returns average combined fuel consumption of 4.1 litres per 100km and CO2 emissions of 95 grams per kilometre – a claimed 30 per cent less than an engine with similar performance – while the Dualogic transmission version lowers those marks to 4.0L/100km and 92g/km.

That makes the DOHC TwinAir engine both 23 per cent more powerful than the two-valve 1.2 and 30 per cent more economical than the four-valve 1.4, as well as 23 per cent shorter and 10 per cent lighter than a comparable four-cylinder engine,.

As such, Fiat says the TwinAir engine is readily adaptable to hybrid and methane injection technologies, which will be fitted next.
