Hyundai Ioniq Hybrid MPG & CO2 emissions

The Ioniq is very efficient compared to a diesel hatchback, but it’s a shame the Toyota Prius manages lower emissions

Hyundai Ioniq Hybrid MPG

The Ioniq Hybrid’s official figures of 103g/km and 62.8mpg shame most diesel rivals, although it does trail behind the Toyota Prius. Real-world economy should be impressive, too, and you’ll likely manage over 50mpg with ease.

There’s even the Ioniq’s ‘ECO-DAS’, or 'Eco Driving Assistant System', which helps keep fuel costs as low as possible by calculating the most efficient navigation route, taking traffic into consideration. It even encourages coasting by giving prior warning of changes in speed limits or road conditions.

CO2 emissions

Emissions of 103g/km are good by diesel-car standards, but the Toyota Prius does undercut the Hyundai Ioniq Hybrid slightly (provided you have it on 15-inch wheels). It’s a shame that neither has free access to the London Congestion Charge Zone, as the electric and plug-in hybrid versions of the Ioniq do.
