[Test Drive] "There Is a Reason for the Bestselling Car"... K5 HEV Combining Design and Fuel Efficiency

[Asia Economy Reporter Suyeon Woo] Since the launch of the 3rd generation complete redesign model, Kia Motors' K5 has consistently ranked first in monthly sales within the Kia brand. Recognized for its design and performance, it quickly surpassed its competitor, the Sonata, to become the best-selling car in the mid-size sedan market.

Thanks to the popularity of the K5, Kia's K-series (K3·K5·K7) sales in March reached 17,608 units, marking a remarkable 62% increase compared to the previous year. To understand why the K5 has captivated consumers, we took the K5 Hybrid model for a test drive and confirmed its appeal firsthand.

First, the design was impressive at a glance. The K5 has been highly praised in the design field since its initial release. While the Sonata is seen as innovative and futuristic, the K5 is evaluated as sophisticated yet distinctive, with a design that does not divide opinions.

The front features Kia’s signature 'Tiger Nose' radiator grille, and the daytime running lights are designed with dynamic graphics reminiscent of a heartbeat. The side adopts a fastback style to emphasize dynamism, and the rear applies dotted LED rear lamps, giving a unique impression.

Sitting in the driver's seat, the position was lower than the previous K5, providing a sense of stability. Thanks to this, the driving experience felt dynamic, as if driving a sports car. To achieve this, Kia extended the K5’s length and width by 50mm and 25mm respectively, while lowering the height by 20mm, creating a sporty sedan.

The interior design is clean and futuristic. A 12.3-inch large cluster screen, touch-type climate control, and a dial-type electronic shift knob were applied, giving the feeling of riding a future car. Additionally, real wood materials used throughout the interior enhanced the sense of luxury.

During driving, the quiet yet powerful Smartstream gasoline 2.0 hybrid engine shone. At low speeds, the electric vehicle (EV) mode operated, producing almost no noise, and when the speed increased beyond a certain point, the gasoline engine engaged to provide additional power.

There was no jerkiness or noticeable change when switching from electric mode to internal combustion engine mode. If the EV mode indicator on the dashboard had not been displayed separately, one would not have noticed the change in the main power source. Fuel efficiency remained above 20 km/l throughout the drive, confirming the greatest strength of the hybrid: efficiency. The K5 Hybrid model is equipped with the Smartstream 2.0 hybrid engine, delivering a maximum output of 152 horsepower and a maximum torque of 19.2 kg·m. Its official combined fuel efficiency is approximately 20.1 km/l.

The K5 Hybrid features a voice recognition system developed in collaboration with Kakao. While driving, commands like "Turn on the heated seat" and "Lower the window" were recognized, and the car automatically activated the seat heater and lowered the window. Also, Kia’s first-ever applied air purification system monitors the indoor air quality in real time and displays it on the climate control screen in four levels (Good, Normal, Bad, Very Bad). The air quality remained at the 'Good' level throughout the ride, but if it dropped to 'Bad,' the system automatically purifies the air through a high-performance filter.

The newly applied navigation-based smart cruise control enhanced driving convenience. We drove on the highway using Highway Driving Assist (HDA). The vehicle automatically recognized the distance between cars ahead and behind, maintaining a consistent speed. When speed limits or speed cameras appeared during the drive, the car autonomously reduced its speed.

Through this test drive, we confirmed the secret behind the K5 Hybrid’s popularity. The K5 is not a model that drives popularity by scoring an 'A+' in a specific area. Rather, it can be defined as a multipurpose vehicle that scores above 'A' in all aspects such as design, fuel efficiency, engine performance, and advanced technology.
