INTRODUCTION
The Kia Optima IV Sportswagon 2.0 GDI Plug-in Hybrid Automatic, launched in 2017 and discontinued in 2018, was a significant addition to Kia’s European lineup. Built on the PF platform, also underpinning the fourth-generation Optima sedan, the Sportswagon offered the practicality of a station wagon combined with the efficiency of a plug-in hybrid powertrain. This model aimed to appeal to environmentally conscious buyers seeking a spacious and well-equipped vehicle. It represented Kia’s commitment to expanding its hybrid and electric vehicle offerings in response to tightening emissions regulations and growing consumer demand for alternative fuel vehicles.
Powertrain & Engine Architecture
At the heart of the Optima Sportswagon PHEV lies a 2.0-liter ‘G4NG’ inline-four cylinder gasoline engine. This engine, utilizing direct injection (GDI) technology, produces 156 horsepower at 6000 rpm and 139.4 lb-ft of torque at 5000 rpm. The engine features a dual continuously variable valve timing (DOHC, Dual CVVT) system to optimize performance and efficiency. Paired with the gasoline engine is a 68 horsepower electric motor, delivering 151.2 lb-ft of torque, integrated between the engine and the six-speed automatic transmission. The electric motor draws power from a 9 kWh lithium-polymer battery pack located under the trunk floor. The combined system output is 205 horsepower and 276.59 lb-ft of torque. The transmission is a conventional six-speed automatic, chosen for its smooth operation and reliability, adapted to work seamlessly with the electric motor. The vehicle can operate in all-electric mode for up to 38.53 miles (62 km) on a full charge, and can achieve a combined fuel economy of 168 US mpg.
Driving Characteristics
The 2.0 GDI Plug-in Hybrid Automatic Optima Sportswagon offers a refined and comfortable driving experience. In electric mode, acceleration is brisk and quiet, ideal for urban driving. When the gasoline engine engages, the transition is generally smooth, although a slight increase in noise is noticeable. The six-speed automatic transmission provides adequate gear changes, but isn’t particularly sporty. Compared to the standard gasoline-powered Optima Sportswagon, the PHEV variant feels slightly heavier due to the battery pack, impacting handling marginally. However, the lower center of gravity contributes to improved stability. The electric motor’s instant torque provides a noticeable boost during acceleration, making the PHEV feel more responsive than the base 1.6L gasoline engine. Compared to the higher-output gasoline engines, this variant prioritizes efficiency over outright performance.
Equipment & Trim Levels
The Optima Sportswagon 2.0 GDI Plug-in Hybrid Automatic typically came well-equipped, reflecting its position as a premium trim level. Standard features included leather upholstery, heated front seats, a touchscreen infotainment system with navigation, a rearview camera, and a suite of advanced driver-assistance systems (ADAS) such as lane departure warning, automatic emergency braking, and adaptive cruise control. Optional extras included a panoramic sunroof, premium sound system, and ventilated front seats. Interior trim was generally dark, with accents of chrome and piano black. The dashboard layout was similar to other Optima Sportswagon models, but with unique hybrid-specific displays showing energy flow and battery status.
Chassis & Braking
The Optima Sportswagon PHEV utilizes a McPherson strut front suspension and a multi-link rear suspension, tuned for comfort and stability. Stabilizer bars are fitted to both axles to reduce body roll. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power. The vehicle is equipped with ABS (Anti-lock Braking System) and electronic stability control. The added weight of the battery pack necessitated slightly stiffer spring rates compared to the standard Optima Sportswagon, but the overall ride quality remained comfortable. The steering is electrically assisted, providing light and precise control.
Market Reception & Comparison
The Kia Optima Sportswagon 2.0 GDI Plug-in Hybrid Automatic received generally positive reviews from automotive critics. It was praised for its fuel efficiency, spacious interior, and generous equipment levels. However, some reviewers noted that the all-electric range was relatively short compared to some competitors. Compared to the standard gasoline-powered Optima Sportswagon, the PHEV variant offered significantly better fuel economy, but at a higher purchase price. Compared to other plug-in hybrid estates, such as the Volkswagen Passat GTE, the Optima Sportswagon offered a competitive package in terms of price and features. Reliability reports have been generally positive, with few major issues reported with the powertrain.
Legacy
The Kia Optima IV Sportswagon 2.0 GDI Plug-in Hybrid Automatic, despite its short production run, played a role in establishing Kia as a serious contender in the plug-in hybrid market. The powertrain, while not without its limitations, proved to be relatively reliable. On the used car market, these models are sought after by buyers looking for a fuel-efficient and well-equipped estate car. The battery pack’s longevity is a key consideration for potential buyers, but with proper maintenance, it can provide many years of service. The Optima Sportswagon PHEV paved the way for Kia’s continued development of hybrid and electric vehicles, contributing to the brand’s growing reputation for innovation and value.
