2016-2018 Kia Optima IV Sportswagon 1.7 CRDI (141 Hp) DCT ISG

Technical Specifications

The Kia Optima IV Sportswagon 1.7 CRDI (141 hp) DCT ISG, launched in 2016, was a key component of Kia’s strategy to broaden its appeal in the European market. Building upon the success of the third-generation Optima sedan, the Sportswagon variant offered increased practicality without sacrificing the stylish design that had become a hallmark of the Optima line. This particular engine and transmission combination represented a mid-range offering, balancing fuel economy with acceptable performance for everyday driving. It was built on the PF platform (also known as the 1HX0/A3 platform), shared with the Hyundai i40 and Sonata.

Powertrain & Engine Architecture

At the heart of this Optima variant lies the U II 1.7-liter four-cylinder diesel engine, internally designated D4FD. This engine utilizes a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A turbocharger with an intercooler further enhances power output and torque. The engine produces 141 horsepower at 4,000 rpm and 340 Nm (250.77 lb-ft) of torque between 1750 and 2500 rpm. The engine features a cast iron block and aluminum cylinder head, with four valves per cylinder. The engine’s Idle Stop & Go (ISG) system automatically shuts off the engine when the vehicle is stationary, such as at traffic lights, to improve fuel efficiency. Paired with the engine is a seven-speed dual-clutch transmission (DCT). This DCT provides quicker and smoother gear changes compared to a traditional automatic transmission, contributing to both performance and fuel economy. The DCT’s programming prioritizes fuel efficiency in normal driving modes.

Driving Characteristics

The 1.7 CRDI with the DCT delivers a comfortable and refined driving experience. While not overtly sporty, the engine provides sufficient power for everyday driving situations, including highway cruising and overtaking. The DCT transmission contributes to responsive acceleration, although some drivers may notice slight hesitation at low speeds. The 0-60 mph time of around 10.5 seconds reflects its focus on efficiency rather than outright speed. The DCT’s gear ratios are tuned to maximize fuel economy, meaning the engine doesn’t always feel as eager to rev as it might in a manual transmission version. Compared to the more powerful 2.0-liter diesel variants, this 1.7 CRDI offers a more relaxed driving experience, prioritizing comfort and fuel savings over performance.

Equipment & Trim Levels

The 1.7 CRDI DCT ISG Sportswagon typically came equipped with a generous level of standard features. These included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and a suite of safety features such as ABS, ESC (Electronic Stability Control), and multiple airbags. Higher trim levels added features like leather upholstery, a panoramic sunroof, heated front seats, and advanced driver-assistance systems (ADAS) such as lane departure warning and autonomous emergency braking. Interior upholstery was typically cloth on lower trims, with leather options available on higher-spec models. Dashboard configuration was consistent across the range, featuring a modern and ergonomic design.

Chassis & Braking

The Optima Sportswagon utilizes an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This configuration provides a good balance between ride comfort and handling. The front brakes are ventilated discs, while the rear brakes are solid discs. The suspension is tuned for comfort, absorbing bumps and imperfections in the road surface effectively. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The steering is electrically assisted, providing a light and precise feel.

Market Reception & Comparison

The Kia Optima IV Sportswagon 1.7 CRDI DCT ISG was generally well-received by automotive critics. It was praised for its stylish design, spacious interior, and fuel efficiency. The DCT transmission was noted for its smoothness and responsiveness, although some reviewers found it slightly less engaging than a traditional manual gearbox. Compared to other diesel estate cars in its class, such as the Ford Mondeo Estate and Volkswagen Passat Estate, the Optima offered a compelling combination of value, features, and warranty coverage. Fuel economy was a key selling point, with the 1.7 CRDI achieving combined figures of around 51.1 US mpg. Reliability was also considered good, although some owners reported minor issues with the DCT transmission.

Legacy

The Kia Optima IV Sportswagon 1.7 CRDI DCT ISG has proven to be a reliable and practical used car option. The 1.7-liter diesel engine, while not known for exceptional longevity, has generally proven durable with regular maintenance. The DCT transmission requires periodic servicing to ensure smooth operation. Today, these vehicles can be found on the used car market at attractive prices, offering a good value proposition for buyers seeking a spacious and fuel-efficient estate car. The Optima Sportswagon helped to establish Kia as a serious contender in the European market, demonstrating the brand’s ability to produce stylish, well-equipped, and reliable vehicles.
