Pipistrel is proud to announce availability of the double NASA Challenge winner Virus SW with the all new Rotax 912 iS fuel injected engine. The 912 iS engine is an evolution from the proven and reliable 912 series, but brings the pilots and operators dramatically improved fuel efficiency, multiple system redundancy and smoother operation, thanks to the long awaited fuel injection system. The system adjusts fuel-air mixture to be optimal for every cylinder at every altitude and throttle setting.

While the performance numbers of the Virus SW do not change, as the 912 iS maintains 100 HP, the fuel consumption decreases dramatically by as much as 21%, preliminary numbers show. This means that the Virus SW equipped with the new Rotax 912 iS cruises at 274 km/h (147 kts) in 15 litres per hour (3.95 gph). What an amazing achievement! It can be said that the double NASA Challenge Winner Virus SW finally got the perfect engine!
