2012 Lexus GS 450h is the most efficient GS ever created by the brand. It includes an advanced petrol-electric hybrid drivetrain which will contribute the model to become of the most efficient vehicles in its class.

Thank to its unique hybrid system, the Lexus' efficient hybrid powerplant consumes just 6.3 litres of fuel per 100km. This means in fact that the new customers will save circa twenty percent from fuel in comparison to the outgoing model. At the same the CO2 emissions have been also reduced significantly to the number of 147g/km.

The performance of this Lexus hybrid vehicle is reassured by a combined power output of 254kW. Thank to it, the 450h can accelerate from 0-100km/h in just 5.9 seconds.

What is more here, compared to its predecessor, the GS 450h also offers greater space and onboard technology. This is mainly due to the redesigned chassis. There is also forty-five percent more boot space which now is increase from 320 to 465 litres.

Another interesting fact here is that the GS 450h is actually the first hybrid vehicle, which comes equipped with all-wheel steering. And in particular, it is the first one to include an Atkinson cycle engine driving the rear wheels, and the first Atkinson cycle engine to feature direct and port injection.

In terms of security and safety features, there are some innovations included, such as: an advanced Pre-Collision safety System (PCS), a Driver Fatigue Monitor camera, and a complementary Adaptive Cruise Control system (ACC). The latter now operates at all speeds down to 0km/h.

Additionally, the safety suite is enhanced by a Blind Spot Monitor, which now comes as a standard to detect vehicles in adjacent lanes, and an expanded Head Up Display (HUD) unit. This unit shows the road speed, cruise control, gear position, turn-by turn navigation and tachometer.

GS 450h models will be offered in three trim levels: Luxury, F Sport and Sports Luxury, which are expected to be launched in June this year.
