Kia Optima 2016–2018 car dimensions: 4855 mm long, 1860 mm wide and 1470 mm high. Unladen weight is 1,550 kg. Braked towing is 1,800 kg.
The cabin has a driver-focused layout with soft-touch materials and a 7- or 8-inch touchscreen nav system as standard. Dual-zone climate control and cruise control with speed limiter come on all grades. Front and rear parking sensors plus a reversing camera are fitted across the range. Higher trims add adaptive cruise, autonomous emergency braking, blind spot detection with rear cross traffic alert, and lane keep assist.
The boot holds 552 litres with seats up, including underfloor trays, and expands to 1686 litres with the 40:20:40 split-fold rear seats down. One-touch folding, luggage rails and a power tailgate on top grades make loading easy.
Braked towing reaches 1800 kg on manual models and 1500 kg on DCT automatics, with 750 kg unbraked. Payload sits around 520 kg depending on engine and trim. Roof rails are standard for extra load options.
The estate layout with luggage nets and rails suits work use, though no heavy-duty cooling or reinforced suspension is listed as standard.
The cabin feels spacious and refined with soft-touch surfaces, real stitching on the dash and doors, and metallic accents. Seats use a stiffer frame with soft foam in the headrest and upper back plus denser foam for thigh support and deeper side bolsters. Higher grades add leather or Nappa trim, multi-way power adjustment with memory and lumbar support, plus heating and ventilation for a quiet, comfortable ride.

Fuel economy varies by powertrain. The 1.7 CRDi diesel delivers up to 64.2 mpg combined and low CO2 figures of 113 g/km on manual models. Petrol options such as the 2.0 CVVL return about 37 mpg combined while the 2.0 T-GDI sits nearer 30 mpg. A plug-in hybrid version later joined the range with even lower official figures.
Servicing is straightforward with intervals typically 15,000 km or 12 months for most petrol engines and 30,000 km or 24 months for diesels. Some turbo petrols call for 10,000 km checks. The 7-year/150,000 km warranty covers the car and transfers to new owners.
Safety is strong. The Optima earned a five-star Euro NCAP result with high adult and child protection scores. The estate shares the same high-strength body using over 50 percent advanced steel. Standard kit covers dual front, side and curtain airbags plus a driver’s knee bag, ESC, VSM, ABS and a reverse camera. Higher grades add AEB with pedestrian detection, blind-spot monitoring, lane-keep assist, rear cross-traffic alert and adaptive cruise.
Living with the estate is easy thanks to 552 litres of boot space that expands to 1,686 litres with the 40:20:40 split rear seats folded. One-touch folding, underfloor storage, luggage rails and an available power tailgate add daily practicality while the quiet cabin and comfortable ride suit long trips.
