One claim made by Hyundai that turned many heads is that the Ioniq has the ability to beat the Toyota Prius in regard to highway mileage. Though there are still not official EPA numbers on that, it seems that other numbers posted by the hybrid Ioniq is worth a look.
It seems that the Ioniq has better performance specs than the Prius, and that is noteworthy considering how much Toyota has emphasized its hybrid’s performance aspects.
Using an enhanced hybrid powertrain from the one that runs that Sonata Hybrid and supposedly superior lithium polymer batteries from LG Chem, the Ioniq has a hybrid output of 139hp and 109lb-ft torque in comparison to 121hp and 105lb-ft in the Prius.
It does so with a 1.6L four-cylinder and a 32kW battery, whereas the Prius combines a 1.8L four-pot with a 53kW battery unit. On paper the Ioniq can sprint to 60mph from a standstill in 10.3 seconds, 0.2 seconds quicker than the Prius despite weighing 32lbs more and having bigger dimensions.
They may have the same wheelbase length but in terms of width, the Ioniq provides an extra 2.4 inches which should mean more lateral space in the cabin. We’re not sure how Hyundai crafted the ergonomics of the cabin and whether or not the extra width is used to the fullest.
