Nov. 18, 2013 /PRNewswire/ -- The 377-horsepower Acura RLX Sport Hybrid SH-AWD luxury-performance sedan will be on public display for the first time tomorrow at the Los Angeles International Auto Show, showcasing Acura's dynamic new three-motor hybrid system.
The 2014 Acura RLX Sport Hybrid SH-AWD, which launches next spring, is the first vehicle to deploy Acura's new three-motor hybrid powertrain technology. The system combines a highly efficient, direct-injected V-6 engine with an all-new, Acura-designed, 7-speed dual clutch transmission with built-in electric motor and an electrically powered variant of Acura's highly regarded torque-vectoring Super Handling All-Wheel Drive (SH-AWD).
This advanced new hybrid powertrain delivers exhilarating driving performance with incredibly responsive power delivery and precise, sure-footed handling performance like no other vehicle in its class. Supported by the instantaneous torque delivered by its high-output electric motors, the RLX Sport Hybrid runs a 0-60 mph time comparable with competitor's V8-powered machines. This performance, however, is coupled with a 28/32/30mpg (city/highway/combined) EPA fuel economy rating
1, which is in the range of 4-cylinder-powered luxury sedans.
Powertrain and DrivetrainThe RLX Sport Hybrid's 3.5-liter, 310-horsepower,
® 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.
