New Acura RXL SH-AWD hybrid Sport 2014  is the latest product from Acura. The Japanese car manufacturer has the exterior design da luxurious interior. Not only popular in Japanese production car from acura is very popular in America and in Europe. The car is very comfortable and has a sophisticated hybrid technology in the show by acura. To be able to compete and superior in product sales, each car manufacturer had to developing the technology.

With the Acura RXL Sport Hybrid SH-AWD Acura is expected to beat the other Japanese car manufacturers such as Toyota and Honda. In these years every car manufacturer competing to bring innovation to developing hybrid technology. Of course, the development of this technology aims to make cars more environmentally friendly and fuel efficient.

TMU Ain’t Just an Airport in Costa Rica
When the subject of this story, the Acura RLX Sport Hybrid SH-AWD—or “SH SH-AWD” for short—was announced, many thought that it would share its hybrid guts with the NSX, only in reverse. That isn’t the case, except perhaps philosophically. The only common bit between the two cars is what Acura calls the twin motor unit (TMU). In the RLX SH SH-AWD, the TMU is fixed to a rubber-isolated subframe at the rear axle and is what enables the RLX hybrid to offer four-wheel drive via two identical 36-hp electric motors that are coupled together by a planetary gearset and produce 54 lb-ft of torque.

  Below 78 mph, each motor can supply torque to its assigned wheel independently via yaw-inducing torque vectoring, or the two can work in concert to contribute thrust or braking. Above 78 mph, the TMU can still perform the torque-vectoring trick, but it ditches its acceleration and deceleration duties. Controlled via electronics and connected to the rest of the powertrain only via wires, the TMU means there’s no driveshaft. It’s unique among torque-vectoring differentials in that it can deliver torque to one tire while the other pulls torque (or, put another way, produces negative torque) and feeds the energy into the regenerative braking system.

As you dive for an apex, you feel the SH SH-AWD’s TMU fend off understeer and revector the car just as well as the mechanically based SH-AWD (Super Handling All-Wheel Drive) system did in the old RL, which was replaced by the RLX. The TMU is doing the lifting at every step away from a stop; the RLX hybrid can operate as a pure electric, rear-wheel-drive car up to about 50 mph provided you’re gentle on the throttle. (So, no, you can’t do lurid drifts.) Another caveat to RWD awesomeness: Range in this mode is limited to a mile or two from the 1.3-kWh lithium-ion battery. If it doesn’t deliver fun or long, silent cruises in the moonlight, the EV mode does allow the 4350-pound Acura to score highly on the EPA’s city mileage test, where it notched 28 mpg. That’s an improvement of 40 percent over the front-drive, nonhybrid RLX. The hybrid’s 32-mpg EPA highway rating is 1 mpg better than that of its conventionally powered sibling, which is to be expected, given that a hybrid is most beneficial in urban driving where it can recapture and use electrical energy more often.
