Lexus has unveiled the RX450h at Geneva, which is a follow up to the previous RX400h model in the line of Lexus Hybrid Drive technologies. The new system boast being capable of functioning solely on electricity and petrol or both according to the drivers needs.
The independent four-wheel drive system featured in the RX400h has been brought forward to the new models and new added systems have increased both power output and fuel efficiency with new technologies such as the Adoption of the Atkinson combustion cycle, Cooled Exhaust Gas Recirculation (EGR), Exhaust Heat Recovery (EHR) and AI-SHIFT control (Artificial Intelligence – SHIFT) to name a few.
The whole system works by 2 individual front and rear driving units which amalgamates the power to propel the vehicle. A 3.5litre V6 petrol engine, a powerful electric motor, a generator, a high performance battery, a power control unit and a power split device with a planetary gear move the power as and when it is needed.
In the rear, an electric motor forms the four wheel drive component and is totally independent from the front section and is controlled and monitored by the Vehicle Dynamics Integrated Management (VDIM) system.
Expect power output of around 295bhp powering the hybrid to a top speed of 124mph with 0 to 62 figures rounding the 7.8 second mark. What is amazing about this car then is that all this performance comes at an incredible 44 miles to the gallon and even more surprising CO2 figure of 148g/km.
