The ultimate Hyundai i10 – at least when calculated in terms of efficiency – is undoubtedly the electrified version pictured above. While battery-powered is about as clean as its gets, Hyundai's new lineup of gasoline-powered i10's will include a 1.0-liter mill that emits just 99g/km of CO2 emissions. Hyundai claims that its 1.0-liter i10 will become the cheapest car with a sub-100g/km emissions rating available in the UK. The revised i10 range will launch at the Paris Motor Show about a month from now.
Hyundai's new 1.0-liter mill features variable valve timing and a host of additional fuel economy-boosting features. Despite its smaller displacement, Hyundai claims that the engine "is not a cheap unit, just a very efficient one." A 1.2-liter engine will join the ultra-efficient 1.0-liter and both powerplants now meet Euro 5 emissions standards. The company is still considering the addition of a petrol-powered three-cylinder engine, but for now, the 99g/km CO2 emissions-rated 1.0-liter mill holds the honor of Hyundai's most fuel-efficient gasoline engine ever offered in the diminutive i10.
