Infiniti introduces 3.0-liter V6 twin-turbo engine: the most advanced V6 for Infiniti
DUBAI: At a special media preview ahead of the North American International Auto Show in Detroit next month, Infiniti has previewed an allnew engine; the 3.0-liter V6 twin-turbo from the new and exclusive ‘VR’ powertrain family. The new compact and lightweight 3.0-liter V6 twinturbo engine is the most advanced V6 engine that Infiniti has ever offered, striking an ideal balance between drivability, efficiency, and performance.
The engine’s reduced weight and contained size is credited, in part, to lighter and more compact cylinder blocks. The result is greater mechanical efficiency, while a series of new features and in-house innovations secure superior performance. “The all-new engine from Infiniti reaffirms our commitment to expanding our powertrain and product portfolio,” said Juergen Schmitz, Managing Director, Infiniti Middle East. “Both versions of the all-new engine will make its Middle East debut in the Infiniti Q50 later in 2016. Since launch the Infiniti Q50 has performed exceptionally well - with a sales growth of 124% for the first eleven months of 2015.
We are confident that with the addition of the new powertrains, it will help Infiniti to further increase its footprint in the region.” The allnew 3.0-liter V6 twin-turbo engine has been developed to deliver optimal power and torque for an engine of its size, together with optimized fuel efficiency. The high-output version of the power unit delivers 400hp (298kW) at 6400 rpm and 475Nm (350lb-ft) maximum torque at 16005200 rpm; while the 300hp (224kW) version (at 6400 rpm) produces 400Nm (295lb-ft) torque at 1600-5200 rpm.
These outputs have been achieved while ensuring an improvement in fuel efficiency of up to 6.7% and this represents a best-in-class power-to-efficiency ratio for the 400hp power unit. This power-to-efficiency performance was made possible thanks to a set of newly-developed features. Advanced timing control ensures improved responsiveness, enabling quicker reactions to driver inputs. Power delivery is enhanced through an advanced new twin-turbo system enabling smooth and immediate responses under acceleration, while aiding efficiency.
An optimized turbine blade design helps the engine generate greater overall performance, with faster turbine revolution speeds allowing for an immediate response from the twin-turbo system.In addition, the V6 engine features a newturbine speed sensor, which allows for the twin-turbo system to perform at up to 220,000 rpm - at steady condition and 240,000 rpm at transient condition- higher than ever before for a V6 power unit. Selected Infiniti models, among them the upgraded Q50, will be equipped with the all-new 3.0-liter V6 twin-turbo from 2016 onwards, with the engine being manufactured at the powertrain plant in Iwaki, Fukushima, Japan.
