Kia Optima 1.7 CRDi Review: 3 Trim Levels, Economy And Space

The Kia Optima 1.7 CRDi stands out in the crowded midsize saloon market with its bold styling, efficient diesel powertrain, and impressive interior space. This model combines practical virtues with a competitive price point, making it appealing for both company car drivers and private owners seeking value without compromise.

Striking Design and Road Presence

From the outset, the Optima commands attention with its aggressive front grille, sleek lines, and low-slung profile. Measuring longer, lower, and wider than many rivals like the Volkswagen Passat, it projects a sporty demeanor that belies its family-friendly nature. The chrome accents and sculpted bodywork give it a premium feel, setting it apart from more conservative estate competitors.

In estate form, known as the Sportswagon, it retains this visual appeal while adding versatility. Reviewers praise its striking appearance among estates, which often prioritize function over form. Available in various trims, higher versions feature larger alloy wheels, LED lighting, and panoramic sunroofs, enhancing its upscale vibe.

Powertrain and Performance Breakdown

At the heart of the Optima is a 1.7-liter CRDi diesel engine producing between 134 and 141 horsepower, paired with either a six-speed manual or optional automatic transmission. Acceleration from 0-62mph ranges from 9.8 to 10.5 seconds, with top speeds around 125mph, offering adequate pace for overtaking and merging.

The diesel unit delivers strong low-end torque—up to 340Nm—ideal for motorway cruising, though it can feel noisy under hard acceleration and requires frequent gear changes in manual form. The Intelligent Stop and Go system aids efficiency, while the dual-clutch automatic in later models provides swift shifts, outperforming traditional automatics in rivals.

This table summarizes key performance metrics drawn from multiple tests, showing consistency across sources.

Fuel Efficiency and Running Costs

One of the Optima’s strongest suits is its frugality. Official combined economy figures hover around 57.6-64.2 mpg, with CO2 emissions between 113-128 g/km, placing it in attractive company car tax bands (22% BIK). Real-world motorway runs often match or exceed these, thanks to the torquey diesel.

Pricing starts at approximately £21,695 for base models, undercutting rivals like the Vauxhall Insignia and Ford Mondeo while offering similar space. Insurance groups around 17 keep costs manageable, and the diesel particulate filter (DPF) ensures compliance with emissions standards. For fleets, monthly BIK at 20/40% is £89/£179, competitive but not class-leading against VW or Skoda.

Driving Experience: Comfort Meets Capability

On motorways, the Optima shines with a compliant ride that absorbs imperfections, though larger wheels can introduce vibrations. The cabin remains hushed at cruising speeds, with the engine pulling cleanly without excessive revs. Steering is light and quick, prioritizing ease over feedback, which suits long journeys but may disappoint enthusiasts.

Twisty roads reveal moderate body control, with front-wheel grip that fades predictably but without drama. The Sportswagon variant feels nimbler due to tuned suspension, offering better agility than the saloon. Overall, it’s accomplished rather than thrilling, with good weighting but limited communication through the wheel.

• Pros: Supple ride, quiet cruising, torquey engine
• Cons: Noisy acceleration, light steering feedback, occasional high-rev feel

Interior Quality and Practicality

Step inside, and the Optima impresses with cavernous space. Rear legroom accommodates tall adults comfortably, surpassing expectations for six-footers. Materials mix soft-touch surfaces with some harder plastics, elevated by wood accents and a logical layout.

Standard equipment is generous: sat-nav, reversing camera, parking sensors, Bluetooth, and dual-zone climate control feature across trims. Premium audio like Harman Kardon and larger touchscreens appear higher up. Boot space in the saloon is ample, while the Sportswagon excels with its load-lugging capacity, making it highly practical for families.

Competitor Comparison

Against the Passat Estate or Skoda Superb, the Optima offers better styling and space but trails in ultimate efficiency and driver engagement. The Mazda6 provides more fun, Vauxhall Insignia more power, yet the Kia edges on value and warranty.

Long-Term Ownership Insights

Over extended tests, the Optima proves reliable with slick gearboxes and low running costs. Motorway prowess and space make it a fleet favorite, though some note the auto’s laziness in non-eco modes. Fuel economy holds up, and maintenance is straightforward.
