To
create its Sonata
Hybrid, Hyundai started with a
modified version of the Sonata's conventional four-cylinder engine and
six-speed transmission, then sandwiched an electric motor in between them.
Supplying electricity is a lithium-polymer battery pack that's lighter and more
compact than traditional nickel-metal hydride batteries. The result is lively
performance along with high fuel economy numbers. Some rival hybrids offer even
better mpg numbers, however, so we suggest checking out a couple other midsize
hybrid sedans before you make a final decision.
Current
Hyundai Sonata Hybrid
At
the core of the Hyundai
Sonata Hybrid midsize sedan is a gasoline-electric hybrid powertrain that
features a 2.4-liter four-cylinder engine producing 159 horsepower and 154
pound-feet of torque, combined with a 35kW electric motor. Together they
produce a peak of 199 hp. Power is sent to the front wheels through a six-speed
automatic transmission with manual shift control.
The
EPA estimates Sonata Hybrid fuel economy at 38 combined. However, in Edmunds
fuel economy testing of both the Sonata Hybrid and the mechanically similar Kia
Optima Hybrid, we found that both fall a few mpg short of these estimates.
Meanwhile, its competitor hybrid sedans are substantially more efficient.
The Hyundai Sonata Hybrid has two
trims levels: base and Hybrid Limited. Base standard features include 16-inch
alloy wheels, a rearview camera, automatic headlights, keyless entry and
ignition, dual-zone automatic climate control, Bluetooth phone and audio
connectivity, Blue Link telematics and a sound system with a USB/iPod
interface. The Limited's added perks include 17-inch alloy wheels, heated front
seats, leather upholstery, an auto-dimming rearview mirror, a navigation system
and an upgraded sound system. The Hybrid Limited also offers an optional
panoramic sunroof.
The
Hybrid's interior is virtually identical to the regular Sonata's, save for the
typical hybrid display that monitors the gasoline-electric powertrain and
coaches the driver on how to drive in a more fuel-efficient manner. Both front
and rear seats offer adult-sized legroom, although there's slightly less rear
headroom than most rivals due to the sloping rear roof line. The quiet cabin
and quality materials add an upscale quality. But as with most hybrids, the
powertrain's battery pack eats into the available trunk space, reducing it from
16.4 to 12.1 cubic feet.
The Hyundai Sonata Hybrid uses a
modified six-speed automatic in lieu of a continuously variable automatic
transmission (CVT) that's common to other hybrids. Some drivers may prefer
this, as it provides a more familiar feel as it works its way through the
gears. Many hybrids have been characterized as having unusual, less-than-smooth
acceleration, but the Sonata Hybrid's less advanced hybrid system (especially
the six-speed automatic transmission) makes it feel more like a regular car.
The brakes, on the other hand, require more acclimation than normal for a
hybrid sedan and drivers may dislike the especially unorthodox feel. We've also
found the Sonata Hybrid's ride and handling to be not as sophisticated as the
class-leading hybrid sedans from Ford and Honda.

Models
The Hyundai Sonata Hybrid
debuted as a 2011 model. The following year brought the Blue Link telematics
system. Potential buyers should note that these earlier Sonata Hybrids were
prone to occasionally shuddering while accelerating at low speeds as well as
having an even more clumsy, uneven braking feel.
For
2013, those issues were addressed with upgrades to the powertrain and battery
pack. That year also brought a bump in trunk capacity, from 10.7 cubic feet to
12.0 cubes. Other than slight feature differences, such as lacking a rearview
camera and a touchscreen audio interface, these post-'13 Sonata Hybrids are
similar to today's version.
