![]() ![]() Although there’s an undercurrent of efficiency machinations happening behind the scenes, the plug-in hybrid drives like a nonhybrid car when the engine is running. The powertrain far outdoes most other hybrids for charm, in part because as you accelerate and the engine joins in you hear good, life-affirming zoomy sounds of revs rising and gears changing. A 60-hp electric motor replaces the hybrid’s 43-hp unit to enable that wider band of electric operation. Keeping a light foot on the throttle, we saw long stretches of 70-mph cruising using only battery power. What’s different is that in place of the hybrid’s 1.6-kWh battery pack, the PHEV has a larger 8.9-kWh version that can be fully charged in just 2.5 hours with Level 2 (240-volt) hardware, enabling what Hyundai anticipates to be 27 miles of all-electric range. There’s a lightweight, low-friction six-speed dual-clutch automatic gearbox, with an electric motor affixed to the transmission’s input and a computer-controlled clutch bringing the engine into or out of the mix. Just as in the Hyundai Ioniq hybrid, the plug-in has a 104-hp 1.6-liter Atkinson-cycle inline-four that claims 40 percent thermal efficiency. ![]() Provided you’re okay with that concept, this is a very pleasant-driving car that applies the charge you put in the battery toward getting as many miles as possible out of what is in the fuel tank. HIGHS: Normal sounding powertrain, perky Sport mode, quiet interior, comfortable.
