Overview
This is the JF-generation UK Optima saloon introduced for 2016, selected in 1.7 CRDi 3 trim with ISG and a six-speed manual gearbox. It is not the previous car that can share the registration year, the Sportswagon, the later 1.6 diesel or the plug-in hybrid. RoadMatch sees a quiet alternative to more obvious family cars for drivers whose mileage supports a diesel and whose luggage fits through a saloon opening. Its useful equipment and passenger room are more important than the badge's prestige. The review is original desk-based synthesis of genuine manufacturer material and independent assessments, not a claim to a first-hand RoadMatch road test.
Exterior and interior
The Optima's long, low profile offers a more restrained alternative to a tall family SUV. Inside, the layout is relatively conventional, with recognisable controls and an emphasis on equipment rather than theatrical design. Auto Express's period test of the 3 supports that distinction: substantial kit does not necessarily create the most inviting cabin. Assess the actual seats, steering adjustment and sightlines before deciding whether the car suits long days. Inspect trim surfaces, the driver's bolster and electrically operated equipment for age-related wear. A well-presented dashboard should not distract from missing keys, damaged switches or a screen that works only intermittently.
Practicality
Kia's JF technical material quotes 510 litres VDA for the conventional saloon. That is a meaningful amount of luggage space, but the separate boot lid cannot reproduce a hatchback's access for tall or awkward items. Try the largest object you carry regularly, paying attention to the opening, hinges and loading height rather than the internal volume alone. Carwow's assessment supports the passenger-space case while noting the less convenient luggage access. Rear-seat suitability still needs to be tested with your front-seat positions and child restraints. The Sportswagon and PHEV have different packaging, so their capacity figures must not be borrowed to make this diesel saloon appear more versatile than it is.
Driving experience
The period independent assessments present the Optima as a comfort-led car, not a family saloon chosen for especially communicative steering. RoadMatch agrees that its strongest role is regular longer travel, where a conventional cabin and settled pace can matter more than quick direction changes. The selected 3 uses larger wheels than the base specification, so include broken urban surfaces and coarse motorway tarmac in a test drive. Check whether tyre noise, seat support and manual shift quality are acceptable for your routine. Neither the automatic's behaviour nor the PHEV's heavier chassis should be transferred to this manual diesel. A representative route is more informative than a short circuit around a smooth dealer forecourt.
Performance
The manufacturer identifies the upgraded 1.7 CRDi at 104 kW or 141 PS, approximately 139 bhp. Its manual acceleration figure is 10.0 seconds to 100 km/h, conventionally shown as 0–62 mph; the automatic's different time should not be substituted. This provides ordinary family-car pace rather than the response implied by sportier trim names. With passengers and luggage aboard, select an appropriate gear before joining faster traffic rather than expecting unlimited low-speed flexibility. Listen for clean engine response and check clutch and gearbox behaviour throughout the drive. A noisy cold diesel is not enough by itself to establish a defect, but inconsistent power, warning lights or clutch judder require proper diagnosis.
Fuel economy
The manufacturer European launch table separates ordinary manual and ISG configurations and carries a wheel-size qualification. Because this UK 3 uses a different wheel specification from that table's stated baseline, RoadMatch does not claim one exact universal official mpg number in the catalogue. The annual budget instead uses a clearly identified 50 mpg planning assumption. That is not an observed road-test result or a guarantee. A diesel makes most sense when trips give it time to warm through and operate normally; frequent short errands can undermine both fuel savings and emissions-system health. Establish the registered car's actual specification and compare its own fuel records, allowing for route and seasonal differences.
Reliability
Kia's original long warranty helped the Optima's purchase proposition when new, but a 2016 car is now beyond its age limit. Condition and maintenance therefore matter more than remembering that headline. Seek invoices that demonstrate regular servicing and investigate clutch, flywheel, emissions or electrical repairs in context. The manual avoids the particular operating characteristics of the dual-clutch automatic, but it still contains wear items that can be costly to replace. Check for warning resets and ask for a proper diagnosis of any intermittent symptom. RoadMatch's moderate-confidence judgement is not a failure statistic and does not borrow an owner's isolated experience as a population-wide verdict. A clean, coherent history is preferable to low mileage with gaps.
Evidence confidence: Moderate. Individual cars vary; service history, condition and previous use matter more than a model-level score.
Safety
Euro NCAP's 2015 JF Optima record identifies a 1.7 diesel saloon test car, making it appropriate official generation context for this review. It must not be confused with the earlier model's assessment, and its historic result is not compared numerically with a current test under different protocols. No protected ratings, percentages or graphics are reproduced here. Assistance equipment varies by trim and market, so verify the UK 3's actual systems rather than assuming every technology described in a European press kit is standard. Check restraint fit, airbag-warning behaviour and repair quality. Run the GOV.UK registration recall check and confirm campaign completion through Kia's VIN records.
Technology and features
The period Auto Express 3-trim test confirms navigation, a reversing camera and upgraded audio among the car's useful equipment. RoadMatch treats them as functions to demonstrate, not reasons to overlook maintenance. Try the camera in a shaded parking area, pair your phone and test the audio and physical controls. Early saloon equipment must not inherit smartphone integration from later Sportswagon or facelift reviews. If a seller promises CarPlay, Android Auto, heated seats or an assistance package, ask for the build record and test it on the actual car. Maps and connected services can also be outdated or subscription-dependent. The value of a conventional dashboard is straightforward operation, provided all its components still work.
Running costs
RoadMatch's 3 October 2026 planning envelope is £5,500–£8,500 to buy and £2,000–£2,600 annually for 8,000 miles. These are original editorial estimates rather than live valuations, insurance quotes or predicted failure bills. The running model assumes 50 mpg and diesel at £1.50 per litre, plus servicing, tyres and a routine maintenance reserve. Insurance, finance, depreciation and major unexpected work remain separate. Obtain a personal insurance quote and confirm tax from the registered vehicle, not a generic 2016 description. Larger tyres and a clutch or emissions-system repair can outweigh modest purchase savings. A documented, sound example is more attractive than a bargain that immediately consumes the ownership contingency.
Advantages and disadvantages
What it does well
- Comfort-oriented long-distance character
- Generous passenger accommodation
- Mid-level 3 has useful original equipment
Where it compromises
- Boot opening less flexible than a hatchback
- Original seven-year warranty has expired
- Diesel is poorly matched to repeated short journeys
Recommended engine and trim
Choose a genuine JF manual diesel with coherent servicing, a healthy clutch and no unresolved emissions faults. Verify the 3 trim's equipment on the car.This is the version we think best balances value, useful equipment, performance and likely running costs. Always verify the exact equipment on the individual advert.
Who it suits and our final verdict
Best suited to: Drivers making regular longer journeys who want a roomy, well-equipped saloon and do not need hatchback or estate loading access.
The Optima is a sensible alternative when bought for comfort and equipment rather than excitement. Its age makes documented condition and a suitable diesel use pattern central to the recommendation.

Before you buy one
A practical starting list for this version, not a substitute for an independent inspection.
- Confirm JF generation and 1.7 CRDi manual identity; registration year alone can include the preceding Optima.
- Check clutch engagement, dual-mass flywheel noise and gear selection from cold and after a longer drive.
- Have diesel particulate-filter and emissions warnings diagnosed, and seek evidence of suitable longer-distance use.
- Inspect the original 18-inch wheels, tyre shoulders and suspension for impact damage or uneven wear.
- Demonstrate the camera, navigation, audio and seat adjustment; do not assume later smartphone integration is fitted.
- Fit your actual largest luggage through the saloon boot opening, not only into its quoted internal volume.
