We are working with our OEM suppliers to improve the fuel Nissan’s Committee for Lighter Vehicle Weight economy performance of these vehicles. Promotion sets weight reduction targets for each model and works in tandem with suppliers to meet Increased Engine Efficiency the targets. The Skyline released in 2001 incorporates an array of aluminum materials, Progress in enhancing engine efficiency was making the model one of the world leaders in achieved by advances in several areas, including lightweight suspension. In addition, the FUGA reducing energy loss caused by friction and released in 2004 was lightened by about 38kg by improving thermal efficiency. In HR and MR partly using aluminum materials. engines announced in 2004, Nissan reduced friction resistance by about 30% through such Development and Expanded measures as applying Nissan technology to polish Use of e-4WD bearing components to a mirror-like finish and applying a machining technique that is usually used Nissan’s e-4WD enhances traction and driving for racing car engines. In addition, we achieved a performance on low-traction surfaces, such as superior fuel combustion speed, which enabled top roads covered in snow or ice, while also improving level combustion efficiency for vehicles in this class fuel economy. The e-4WD is the world’s lightest and improved “real-world fuel economy*” and and most compact electric four-wheel-drive acceleration performance. system. Nissan estimates the e-4WD system offers * Real-world fuel economy: a vehicle’s average fuel economy as over 5% better fuel economy than conventional measured by Nissan, based on the mix of fuel economy tests 4WD systems.
