In addition to improving fuel consumption compared to conventional hydraulic power assist systems, Electronic Power Steering (EPS) improves responsiveness and feel, while the electric motor's cooling oil pump only operates when needed at high temperatures. The air conditioning compressor is also electric instead of driven from the gasoline engine.
In addition to its Normal driving mode, the HS Hybrid offers drivers the ability to choose between ECO, Power and EV modes .
By removing the physical link to the transmission, Shift-by-Wire technologies allowed the designers of the HS 250h to free up interior space that would have been taken up by the shifter.
The Exhaust Heat-Recovery system reduces engine warm-up time, thus allowing it to stop earlier, more often and for longer periods. This accounts for as much as a 7% increase in efficiency at low temperatures.
Pairing ingenuity with efficiency, regenerative braking converts braking energy into electricity to recharge the batteries, while the enhanced Electronically Controlled Braking (ECB) System is lighter, smaller and uses up to 29% less power than our previous regenerative braking system.
