The '''Kia K5''' ({{langx|ko|기아 K5}}), formerly known as the '''Kia Optima''' ({{langx|ko|기아 옵티마}}), is a [[mid-size car]] manufactured by [[Kia]] since 2000 and marketed globally through various [[nameplate]]s. First generation cars were mostly marketed as the Optima, although the '''Kia Magentis''' name was used in [[Europe]] and [[Canada]] when sales began there in 2002. For the second-generation models, Kia used the '''Kia Lotze''' and '''Kia K5''' name for the [[South Korea]]n market, and the Magentis name globally, except in the [[United States]], [[Canada]], [[Malaysia]] and the [[Middle East]], where the Optima name was retained until the 2021 model year. The K5 name is used for all markets since the introduction of the fifth generation in 2019.

It was first shown in [[South Korea]] in July 2000 and was the first product of the Kia-Hyundai platform integration plan.{{fact|date=July 2025}}

In Australia, the Optima was introduced in May 2001, offered only with a 2.5 L V6 engine, and choice of manual or [[automatic transmission]]. The updated Optima was offered with a new 2.7 L engine, 4-speed automatic (the manual was dropped), and features such as full leather interior and alloy wheels were made standard. Thanks in part to better marketing, sales increased to 41,289 units in 2005, an all-time high. The Optima was sold until 2006, when it was replaced by the Magentis.{{fact|date=July 2025}}

===Safety=== The 2001 Optima received Poor to Average ratings from the [[Insurance Institute for Highway Safety]] (IIHS).<ref>{{cite web |url=http://www.iihs.org/iihs/ratings/vehicle/v/kia/optima-4-door-sedan/2001 |title=2001 Kia Optima |work=IIHS |publisher=[[Insurance Institute for Highway Safety]] |access-date=29 May 2017}}</ref>

===Update=== The 2002 Optima received a minor update. A luxurious version of the Optima was sold in [[South Korea]] as the "Optima Regal", using the 2-liter four or the 2.5-liter V6 only. The [[grille (motor vehicle)|grille]] was redesigned for the [[United States]] in 2003 (2004 model year) to feature the Kia badge, and the headlamps were restyled for 2004 (2005 model year).

This generation differed further from the [[Hyundai Sonata]] donor vehicle than the previous model. Unlike the previous Optima though, this vehicle uses a global platform, unique to Kia, designated "MG". The car continues to be built in [[South Korea]] and shares its 2.4-liter [[inline-four engine]], five-speed ''[[Tiptronic|Sportmatic]]'' [[automatic transmission|automatic]] or five-speed [[manual transmission]] with the Sonata.

In addition to the 2.4-liter inline-four and the 2.7-liter V6 offered in North America, globally the Optima/Magentis/Lotze was also available with smaller, 1.8- or 2.0-liter fours, as well as a 2.0-liter [[Turbo-diesel|turbodiesel]] engine. South Korean buyers also received and LPG-powered version of the 2.4. The second generation Optima was launched in Malaysia on 15 August 2007 powered by a 2.0-liter Theta [[DOHC]] [[CVVT]] engine with a 4-speed automatic transmission.

===Safety=== The Optima received a crash test rating of five stars from the [[National Highway Traffic Safety Administration|NHTSA]],<ref>{{cite web|url=http://www.kia.com/optima/optima-safety.php |title=internationallanding |publisher=Kia.com |access-date=2 November 2009}}</ref> and four stars from [[Euro NCAP]].<ref>{{cite web|url=http://www.carpages.co.uk/kia/kia-magentis-review-part-1-03-12-06.asp |title=Kia Magentis Review |publisher=Carpages.co.uk |access-date=2 November 2009}}</ref> The 2006 Optima received Marginal to Good ratings from the [[Insurance Institute for Highway Safety]] (IIHS).<ref>{{cite web |url=http://www.iihs.org/iihs/ratings/vehicle/v/kia/optima-4-door-sedan/2006 |title=2006 Kia Optima |work=IIHS |publisher=[[Insurance Institute for Highway Safety]] |access-date=29 May 2017}}</ref>

The Optima was revised and updated in 2008, debuting at the [[New York International Auto Show#2008|New York International Auto Show]] (as a 2009 model year). This update features new front-end styling and tail lamps. In addition to the revised exterior, length is also slightly increased by roughly {{convert|70|mm|in}} to approximately {{convert|4800|mm|in|abbr=on}} long. There is also a new engine and the interior has also been revised.<ref>{{cite web |url=http://www.thetorquereport.com/2008/03/2009_kia_optima_debuts_in_new.html |title=Redesigned 2009 Kia Optima Debuts in New York |date=2008-03-20 |archive-url=https://archive.today/20120912034815/http://www.thetorquereport.com/2008/03/2009_kia_optima_debuts_in_new.html |archive-date=2012-09-12}}</ref> Main changes in the interior are a redesigned instrument cluster and a [[Sirius Satellite Radio]]/AM/FM/MP3/CD with an auxiliary jack. In certain markets, the option of satellite navigation is offered.

The new ''[[Hyundai Theta engine|Theta II]]'' 2.4-liter I4 employs dual continuously [[variable valve timing]] (CVVT) and a variable intake system (VIS) to increase power to {{convert|131|kW|hp|abbr=on}}, while returning improved fuel consumption over its predecessor. Torque is rated at {{convert|229|Nm|abbr=on}}. There is a 2.0L I4 for other markets with either a 5-speed manual or 4-speed automatic transmission. Power is rated at {{Convert|164|hp|kW|0|abbr=on}} at 6200 RPM and {{Convert|197|Nm|lb·ft|abbr=on}} of torque. Acceleration for the 2.0L is {{convert|0|-|100|km/h|abbr=on}} in 9.2 seconds for the 5-speed manual and 10.1 seconds for the 4-speed automatic. Top speed rated up to {{Convert|208|km/h|mi/h|0|abbr=on}} outside of the US. The 2.7-liter [[V6]] offers few changes to the previous model, though power is increased to {{convert|144|kW|hp|abbr=on}}, and torque to {{convert|249|Nm|abbr=on}}. Acceleration for the 5-speed automatic takes it from {{Convert|0|-|60|mi/h|km/h|abbr=on}} in 8.9sec with a top speed up to {{Convert|220|km/h|mi/h|0|abbr=on}}. A five-speed manual transmission is standard in the base model, and a five-speed automatic is included with mid- and high-end levels (or as an option in the base model).

2010 models see the addition of a [[Electronic key|Proximity Key]] with Push-Button Start and [[paddle shifters]] on SX models.

In Australia, the Magentis was introduced in August 2006, and replaced the Optima. Initially available with a choice of 2.4 L 4-cylinder or 2.7 L V6 engines, the Magentis' sales never caught on, with sales peaking at only 741 units in 2007. In 2008, the V6 engine was dropped, as was the EX-L model, leaving only the entry-level 2.4 L EX on sale until its discontinuation in 2009. While the facelifted 2010 model was never officially launched, a very small number were imported for "evaluation" purposes, and eventually sold to the public as demos.

The completely redesigned Optima, sharing the same platform as its sibling [[Hyundai i40]], marked the introduction of the '''Kia K5''' name - in the South Korean and Chinese markets only, for this generation. It made its world debut at the [[New York International Auto Show#2010|2010 New York International Auto Show]]. It features a new profile designed by Kia design chief [[Peter Schreyer]], following the new design language featured on the [[Kia Forte]], [[Kia Sorento]], and [[Kia Sportage]] and [[Kia Cadenza]] — and using Kia's new corporate grille, known as the [[Kia Motors#Design emphasis|Tiger Nose]], also designed by Schreyer. Lead designer of the TF in the team of Peter Schreyer and Miklos Kovacs was the Italian Davide Limongelli. For the first time, this model will be using the Optima name worldwide, where the Magentis name had been used previously.

As with its [[Hyundai Sonata]] sibling, the Optima's lineup has been replaced with a GDI 2.4-liter four-cylinder engine, either mated to a 6-speed [[automatic transmission]] with Eco dash display, or to a 6-speed [[manual transmission]] that is standard on only the LX model. Sales began in fall 2010. The new K5 was released in the South Korean market on 29 April 2010.

The new Optima retains its trim lines of the base LX, upscale EX, and sporty SX models. Standard equipment includes safety features such as [[electronic stability control]] (ESC) and [[Anti-lock braking system|ABS]] brakes, as well as Sirius Satellite Radio, cooled glove box, [[iPod]] connectivity, and handsfree [[Bluetooth]] phone operation. Starting in October 2013, on LX models, Kia will offer the [[Kia UVO|UVO]] infotainment system by [[Microsoft]] as part of the convenience package. EX model options include Kia's new [[Kia UVO|UVO]] infotainment system by [[Microsoft]], integrated backup camera, and [[Electronic key|Proximity Key]] with Push-Button Start. A panoramic [[Sunroof|moonroof]], heated and cooled front seats, heated rear seats and a navigation system are also available. SX models add a rear [[spoiler (automotive)|spoiler]], metal pedals, black hybrid metal and carbon insert trim, paddle shifters, and illuminated scuff plates. The third generation Optima came with two different ignition options. On some, the ignition is fitted to the steering column with a turn key. In certain specifications, the keyhole is inside of the glove box, with a start button located on the dashboard.

Kia Optima assembly in Iraq In 2015, the Babylon Automobile Plant, located in Babylon Governorate, [[Iraq]], began assembling the Kia Optima from complete knock-down (CKD) kits. The operation was part of a partnership between Iraqi state-owned enterprises and Kia’s regional distributors. Imported body shells, engines, transmissions, and other components were assembled locally on production lines that included chassis fitting, engine installation, interior trim, and quality-control testing. The plant’s reported capacity ranged from 24 to 44 vehicles per day, depending on model mix and demand.

The only externally apparent features that differentiate it from the Kia Optima are the hybrid badging, application specific wheel design, a lowered ride height by approximately {{convert|1|in|mm|abbr=on}}, and the availability of a special light platinum graphite paint color. It also utilizes an active shutter system behind the upper grille, allowing the car to redirect airflow when the gas engine's heat levels allow (such as when the car is operating in [[Electric vehicle|EV]] mode to improve aerodynamics, or to assist in more rapid warming up of the gas engine).<ref>{{Cite web | url=http://www.motorweek.org/reviews/road_tests/2011_kia_optima_hybrid | title=2011 Kia Optima Hybrid | MotorWeek}}</ref>

In September 2011, the Optima Hybrid set a [[Guinness World Record]] for "Lowest Fuel Consumption in a Hybrid Gasoline Vehicle" while driving across the continental United States for 14 days, starting from the Kia factory in West Point, Georgia. In its 7,899-mile drive across the 48 states, the car recorded an average of 64.55 miles per gallon while consuming a total of five and a half tanks of gasoline. In order to qualify for the record, the car had two people and luggage throughout the entire trip.<ref name="USA Today">{{cite news |url=http://content.usatoday.com/communities/driveon/post/2011/09/kia-optima-hybrid-guiness-record-lowest-fuel-consumption-hypermilers/1#.UKbpN4b4Kgc |title=Kia Optima Hybrid sets hypermiling fuel economy record |author=Woodyard, Chris |newspaper=[[USA Today]] |date=13 September 2011 |access-date=17 November 2012}}</ref><ref name="WSJ Blog">{{cite news |url=https://blogs.wsj.com/drivers-seat/2011/09/13/kia-optima-sets-guinness-record-for-fuel-economy/ |title=Kia Optima Sets Guinness Record for Fuel Economy |author=Welsh, Jonathan |newspaper=[[The Wall Street Journal]] |date=13 September 2011 |access-date=17 November 2012}}</ref>
