The main technologies featured in the Hi-cross concept were the new engine and transmission.
Engine Instead of the traditional displacement
V6 engine, the Hi-cross was equipped with a
hybrid 2.0-liter
direct injection petrol engine and a lithium-ion battery-powered electric motor. The Hi-cross would mainly rely on the petrol engine for power, while the electric motor reduced emissions and increased the fuel economy. The power output was expected to achieve the level of a 2.5-liter engine. A "one-motor, two-clutch" system involved a first clutch between the patrol engine and the electric motor, for fully decoupling them in electric mode. The second clutch was behind the transmission to make a smooth transition between the two. This led to energy savings and increased efficiency.
Transmission The Hi-cross featured a new generation of the XTRONIC
CVT. It adopted the HEV drivetrain, which was based on the technology modified by four-wheel drive models rather than front-wheel drive wheels from before. The new system led to a 10 percent improvement in fuel emissions from the previous generation's CVT. The XTRONIC CVT would be low-friction and had smaller shaft-diameter pulleys, which would provide the widest ratio coverage for smoother shifting. It would be better coordinated with the hybrid engine and the new four-wheel system. == References ==
