![]() ![]() It is available in two states of tune – 400 horsepower or 300 horsepower – and is a more than worthy successor to the renowned, highly awarded "VQ-series" V6 that has been a mainstay of INFINITI performance models for many years. Both of the new VR-series engines have been developed to provide an ideal mix of drivability, efficiency and performance. Around 85 percent of the parts utilized in the VR-series V6 are different from those used in the previous VQ-series V6. While the all-new power unit is 19 percent smaller in capacity than the Q50's previous 3.7-liter V6, it adopts a series of innovative technologies to deliver a more engaging driving experience. #Infinity qx80 cargo net eye hooks series# Chief among these is a new direct-injection gasoline (DIG) fueling system. The high-pressure DIG system allows for more precise injection of fuel into the combustion chamber, delivering the exact amount required for smooth engine acceleration, depending on throttle position and engine speed. This system makes the new V6 the cleanest and most fuel-efficient engine of its type that INFINITI has ever offered, contributing towards the 6.7 percent improvement in fuel economy. The engine also features lightweight aluminum construction and low mechanical friction – providing smooth, durable and highly responsive performance. Chief among the engine's weight-saving elements is the adoption of spray bore coating for the engine block and integrated exhaust manifold for cylinder heads. Not only does this make the engine lighter, but this also aids cooling as heat can dissipate more effectively. One of the many other significant features is the adoption of a new integrated exhaust manifold, built into the cylinder head, which positions the catalytic converter closer to the exhaust point. This results in a shorter flow path for the hot exhaust gases, allowing the catalytic converter to heat up almost instantly – twice as fast as previous V6 engines – improving response, while also reducing emissions from a cold start. #Infinity qx80 cargo net eye hooks series#.
