Hyundai Tweaks 2018 Sonata Hybrid, PHEV at Chicago Auto Show

Hyundai Tweaks 2018 Sonata Hybrid, PHEV at Chicago Auto Show

By Philly Murtha, February 09, 2018
Hyundai this week debuted Hybrid and Plug-in Hybrid (PHEV) variants of its 2018 Sonata midsize sedan at the Chicago Auto Show. Mild exterior and interior updates plus more safety features have been added to the 2018 alternative powertrain Sonatas, which will be sold in 10 U.S. states, including California, in the first and second quarters of 2018.

On the outside, Hyundai adds a new grille, hood and tweaks fender design plus modifying the rear with new deck lid, bumper and tail lights. Adaptive front LED lighting systems are added. Additionally, stiffer suspension and steering assist improve handling. Both variants will ride on 16-in. or 17-in. eco-designed wheels. Inside the cabin features a revised instrument panel center stack and infotainment system along with a feature-rich steering wheel that can be order with heat.

Standard advanced safety systems now include blind-spot detection with rear cross-traffic alert and lane change assist. Automatic emergency braking is optional. In addition, an audio/video navigation system features a Bird’s Eye view map. Wireless connectivity and front and back seat phone charging are offered on models with navigation.

Hyundai’s fourth-generation Sonata Hybrid’s powertrain nearly matches the prior one. Power comes from a 2.0-liter 4-cylinder engine that makes 154 horsepower and 140 lb.-ft. of torque, partnered with a 6-speed automatic. Combined with a 38 kW electric motor and clutch, the Hybrid’s total power reaches 193 horsepower. A 1.76 kW lithium battery pack stores flat in the trunk. With an innovative transmission that uses an electric oil pump, the Hybrid’s range is 650 miles and EPA mileage rating estimates 42 mpg in combined city/highway driving. .

The Sonata PHEV is similar to the Hybrid except that it has an extended all-electric range. A 9.8 kW battery pack, five times more powerful than in the Hybrid, provides an EPA-estimated electric range of 27 miles before a recharge that takes less than three hours. A more powerful 50 kW electric motor combined with the 2.0-liter gasoline engine provides about 202 horsepower.
