英菲尼迪在去年曾发布过一款Q60 Project Black S概念车，该车采用了F1混动技术，该技术由雷诺运动车部门开发。而在最近开幕的巴黎车展上，车厂再次发布了搭载混动系统的Project Black S原型车，该车基于英菲尼迪在去年发布的Q60RedSport400，但搭载了升级版动力系统。新的ProjectBlackS原型车结合了英菲尼迪的VR303.0升V6双涡轮增压引擎和专属能量回收系统，综合功率420千瓦/563马力，扭矩475牛米。车辆百公里加速时间不到4秒，2017款车型的综合功率为373千瓦/500马力。据车厂介绍，该车的功率和加速性高于目前任何一款英菲尼迪车型。该车动力系统共配备了三个发电机单元，其中一台电机可以通过回收制动系统动能，另外两台通过吸收排气热量实现能量回收，其产生的电能都会存储至容量为4.4千瓦时的电池组当中。这些能量用于提升涡轮叶片转速，可产生120千瓦/160马力的动力。动力通过后轴的最终驱动组件重新进入动力系统。
Infiniti Project Black S Prototype Brings F1 Hybrid Tech To Paris
Back in 2017, Infiniti unveiled the Q60 Project Black S. The automaker billed it as an exploration of blending Formula 1 hybrid technology – from the RenaultSport Formula One Team – with a road car. Fast forward to today, and the company is again touting hybridization with the Project Black S prototype. It looks similar to the 2017 concept. The new prototype is based off the Infiniti Q60 Red Sport 400 just like the 2017 concept; however, the new one packs an updated powertrain.
The new Project Black S prototype combines Infiniti’s VR30 twin-turbocharged 3.0-liter V6 with a unique energy recovery system. Combined output is 563 horsepower (420 kilowatts) and 350 pound-feet (475 Newton-meters) of torque, which allows the car to achieve a sub-four-second zero-to-62 (100 kilometers per hour) time. The 2017 concept produced a combined output of 500 hp (373 kW). Project Black S produces more power and accelerates more quickly than any Infiniti road car to date, according to the automaker.
The Project Black S uses three motor generator units (MGU). The single MGU-K (kinetic) unit harvests kinetic energy from braking. There are two MGU-H (heat) units that harvest heat energy from exhaust gases, allowing the car to generate electrical power during braking and acceleration, according to Infiniti. Energy collected by the three MGUs is stored in a high-rate discharge 4.4 kWh lithium-ion battery located in the rear compartment. The energy is used to spool up the turbine blades in the turbos and used to deliver up to 160 hp (120 kW) of power into the drivetrain. The power reenters the drivetrain through a newly-designed final drive assembly on the rear axle.
The Infiniti Project Black S prototype will make its official debut at the Paris Motor Show Oct. 1. Infiniti will release more information then.
