Fiat is working on its new two-cylinder engines, which will be fitted to Fiat's ultra-low-cost car that should be out in the market by 2010-11. But, no, we don't think the new car will be anywhere as charismatic as the old, 1960s Fiat 500...
After its acclaimed MultiJet common-rail direct-injection diesel engine technology, Fiat seems to be all set to shake things up with petrol engines as well. The Fiat Group has now introduced ‘MultiAir,’ a new technology for petrol engines, which will help cut down on fuel consumption, reduce emissions and boost power and torque!
According to Fiat, MultiAir petrol engines will be up to 10% more powerful (compared to petrol engines of similar capacity, but without MultiAir), have up to 15% better low-rpm torque and will consume about 10% less fuel. With turbocharging, MultiAir engines could deliver up to 25% better fuel economy.
MultiAir engines will also help reduce emissions – a 40% reduction for unburnt hydrocarbons and carbon monoxide (HC/CO) and a 60% reduction for oxides of nitrogen (NOx). Finally, Fiat also claims MultiAir engines will provide improved throttle response and enhance driving pleasure.
While MultiAir technology may find its first application on Fiat’s petrol engines, the technology itself is applicable to all IC engines, regardless of the fuel used. Hence diesel engines will also, ultimately, stand to benefit from this.
The first production car to be equipped with MultiAir will be the Alfa-Romeo MiTo, which will get this new technology for its 1.4-litre normally aspirated and turbocharged petrol engines. Fiat will also use MultiAir on a new range of two-cylinder engines it’s developing, which would be used on Fiat’s new ultra low cost car that could be somewhat similar to the Tata Nano Europa.
