Art St. Cyr. Vice President-Product Planning and Logisistics, American Honda talked to Lou Ann Hammond, CEO, Driving the Nation about Earth dreams and the Acura RLX SH-AWD.
Honda has 3 different technologies, i-DCD, i_mmd and the SH-AWD. The Acura RLX SH-AWD was unveiled at the 2013 Los Angeles auto show.
St. Cyr talks about the RLX and the three-motor hybrid powertrain technology sport handling – all-wheel drive (SH-AWD) with torque vectoring that debuted on the Acura RLX. The Acura RLX Sport Hybrid’s 3.5-liter, 310-horsepower, i-VTEC® V-6 engine with Variable Cylinder Management (VCM) includes an idle-stop feature to help maximize fuel efficiency. The engine is mated to an all-new, 7-speed dual clutch transmission with built-in electric motor. In automatic mode, the transmission provides highly responsive and intuitive gear selection, including matching engine revs during downshifts, in manual mode, the Sequential SportShift paddle shifters give the driver gear selection control to make virtually seamless ratio changes.
The electric SH-AWD system on the RLX Sport Hybrid eliminates the conventional drive shaft and rear differential, replacing them with two high-output 27-kilowatt electric motors. The rear motors dynamically distribute both positive (drive) and negative (regenerative braking) electric-motor torque, depending on driving conditions, and which torque vectoring assists in cornering. The system is further aided by a 35-kilowatt front electric motor that supplements engine torque to the front wheels and provides regenerative brake torque to charge the vehicle’s 260-volt lithium-ion battery pack.
The Acura RLX SH-AWD has 28/32/30mpg (city/highway/combined) EPA fuel economy rating.
