The 2.5 Turbo Hybrid system features a parallel structure with a starter motor (P1) responsible for engine starting and power generation, and a drive motor (P2) for propulsion and regenerative braking.
The 2.5 Turbo Hybrid system boasts a combined maximum output of 352 horsepower (PS) and a maximum torque of 54.0 kgf·m, representing an increase of approximately 16% in power and 26% in torque compared to the GV80 2.5 Turbo model.
This performance allows the vehicle to accelerate from a standstill to 100 km/h in about 7.1 seconds, based on internal testing standards. The combined fuel efficiency for the GV80 19-inch 2WD five-passenger model has improved by over 25% compared to the gasoline model.
A notable feature is the introduction of a liquid-cooled hybrid battery system, the first of its kind in Hyundai Motor Group's hybrid systems. This system efficiently controls battery temperature, allowing for higher maximum discharge output compared to air-cooled systems, and enables more effective battery usage. It also expands the areas where the motor is used, providing a quieter driving experience and linear acceleration, achieving an electric vehicle-like driving feel.
To minimize vibrations and noise that may occur during engine startup after parking, Genesis developed the vehicle to utilize EV mode until it reaches approximately 30 km/h after departure. This allows for quiet movement in noisy environments, such as underground parking lots, and engages the engine for driving at higher speeds on regular roads, ensuring a comfortable start for customers.
The vehicle also maximizes the use of EV mode in urban areas with frequent traffic signals or stop-and-go conditions, enhancing the quiet driving environment.
Additionally, Genesis has set the final drive gear ratio (FGR) of the 2.5 Turbo Hybrid system's transmission lower than that of the 2.5 Turbo model to ensure drivetrain quietness.
The introduction of technology to reduce both torsional and bending vibrations in the engine crankshaft damper pulley has also decreased engine noise. A new seven-speed rear transmission features a rotary vibration absorber (CPA) damper to counteract engine rotational vibrations, further enhancing interior quietness.
The vehicle provides immediate acceleration response typical of electric vehicles. When the driver presses the accelerator pedal during EV driving, the system simultaneously controls the transmission and engine clutch engagement to achieve instant acceleration using the engine.
According to internal measurements, the GV80 Hybrid can accelerate approximately 18% faster than the 2.5 gasoline turbo model when increasing speed from 100 km/h, demonstrating agile power performance in overtaking situations.
The P2 motor has been developed to enable reverse driving by optimizing the structure to eliminate elements related to the transmission's R gear, increasing the first gear ratio for reverse to ensure performance without engine involvement.
This optimization reduces the weight and friction elements of the transmission, enhancing power delivery efficiency while also providing superior acceleration performance during starts from a stop using the first gear.
Genesis has also incorporated several hybrid-specific features into the 2.5 Turbo Hybrid system, including Stay Mode, Hybrid Predictive Control (HPC), and Smart Regenerative Braking.
Stay Mode allows the use of all vehicle convenience features, including climate control and multimedia, without starting the engine, providing a comfortable experience for customers while the vehicle is stationary.
HPC predicts the driving route and road conditions to optimize battery charge levels, ensuring efficient driving modes are activated.
Smart Regenerative Braking automatically applies optimal regenerative braking force based on navigation information, such as speed cameras and following distance, reducing driver fatigue and increasing battery charge through regenerative braking, thus improving fuel efficiency.
Genesis also unveiled the design of the GV80 Hybrid on the same day.
The vehicle features a newly designed exterior grille and wheels, enhancing its luxurious image. Inside, four new two-tone color options have been added, including Obsidian Black and Tyga Green, as well as Ultramarine Blue and Travertine Beige. Two new wood-grain garnish options have been introduced, along with a quilted pattern, providing a variety of choices.
Lee Si-hyuk, Executive Vice President of Genesis Business Division, stated, "The new powertrain is expected to achieve a refined balance of efficiency, quietness, and driving performance, delivering a differentiated driving experience. We will proactively respond to market changes and customer needs, starting with the GV80 Hybrid."
