The Infiniti QX60 5L 4-cylinder QR25DE Hybrid engine is a sophisticated powertrain option for the Infiniti QX60, specifically from the fourth quarter production in 2021 and beyond, with the engine model number being 660-10198. This engine is unique, as it is part of Infiniti's hybrid lineup.
This 5-liter, or 5.0-liter, engine boasts an innovative design that offers a smooth, powerful driving experience with improved fuel efficiency. The QR25DE engine is a 4-cylinder powerhouse, featuring a dual overhead camshaft design and four valves per cylinder. With a total displacement capacity of 5.0 liters, each cylinder in the engine measures exactly 2.5 liters.
The QX60 with the QR25DE Hybrid engine is an eco-conscious vehicle option. The hybrid system, combined with the internal combustion engine, feeds electricity back into the vehicle's battery, resulting in a more efficient powertrain. The Infiniti Hybrid System control module manages the intricacies of the power distribution between the gasoline engine and electric motor to offer the best possible driving experience.
Infiniti designed this engine with a focus on sophistication and performance. The QR25DE engine features a high-pressure die-cast aluminum engine block and bedplate, minimizing weight while maintaining durability. Additionally, the cylinder head consists of an aluminum alloy to allow for high-efficiency cooling, as well as to reduce emissions.
Unique to the Infiniti QR25DE Hybrid engine is its Drive-by-Wire (DBW) throttle control system, which optimizes engine performance and efficiency by using electrical signals instead of a conventional mechanical throttle cable. This advanced technology ensures precise control and smooth power delivery to the wheels.
One of the most significant improvements in the QR25DE Hybrid engine is the Variable Valve Event & Lift System (VVEL). This system uses a continuously variable valve timing control system and electronically controlled variable valve lift in both the intake and exhaust tracts. This innovative technology optimizes engine performance, reducing emissions and improving fuel economy, ensuring a more enjoyable and responsive driving experience for the QX60 driver.
In summary, the Infiniti QX60 5L 4-cylinder QR25DE Hybrid engine is an advanced, powerful, and efficient powertrain option. It features a sophisticated design, improving fuel efficiency for the QX60, while also offering the smooth and responsive performance that Infiniti vehicles are known for. This engine is specifically for QX60 models from the fourth quarter of 2021 and later, making it a desirable choice for those seeking a capable and eco-conscious vehicle experience.
