As a whole, the Kia Optima Hybrid is new for 2017, but its main components are not.
Its body was introduced on non-hybrid Optima models for the 2016 model year, while its powertrain debuted in the Hyundai Sonata Hybrid, also for 2016.
That powertrain includes a 2.0-liter 4-cylinder engine and 6-speed automatic transmission, working with an electric motor.
While the Optima and Sonata share both a powertrain and basic underpinnings, the Optima Hybrid edges its sibling by 2 mpg in EPA combined fuel economy.
The Optima is also available as a plug-in hybrid, with an EPA-rated 29 miles of electric range.

Introduced for the 2016 model year, the current-generation Sonata Hybrid transitioned to the 2017 model year with few changes.
As stated above, it uses the same powertrain as its Kia Optima Hybrid sibling.
Hyundai owns Kia, so many of the two Korean automakers' models share powertrains and platforms, in what is a common practice in the auto industry.
The companion Sonata Plug-In Hybrid is rated at 22 miles of electric range by the EPA.

The Toyota Camry Hybrid currently sits at the bottom of fuel-efficiency rankings for hybrid mid-size sedans, but that may change when a redesigned version appears for the 2018 model year.
Note that fuel economy is slightly higher for the LE model than the SE and XLE trim levels.
All versions use a 2.5-liter Atkinson-cycle 4-cylinder engine, with the ubiquitous Toyota Hybrid Synergy Drive system.
Toyota remains the leader by far in hybrid sales, and the Camry Hybrid helped pioneer the mid-size sedan hybrid segment.

COMING SOON: 2018 Toyota Camry Hybrid
A redesigned Camry Hybrid was unveiled in January at the 2017 Detroit Auto Show, as part of a complete overhaul of the Camry lineup.
Toyota claims "best-in-class" fuel economy for this latest version of its hybrid mid-size sedan, meaning it must surpass the Honda Accord Hybrid's 48 mpg.
The hybrid Camry will continue to use a 2.5-liter 4-cylinder engine, optimized to work with what the company calls its Toyota Hybrid System II, effectively the successor to the current Hybrid Synergy Drive system.
The new Camry also uses elements of the Toyota New Global Architecture component set that underpins the current-generation Prius.
Like the Prius, the Camry Hybrid will also be offered with two battery-pack options.
Base models are expected to get a nickel-metal hydride pack, while higher-level models will use lithium-ion chemistry.
