The new hybrid system used by Lexus for the 2013 S 450H has a V6 Atkinson-cycle engine that runs on gas and a pair of electric motors for the rear wheels. This revised hybrid system achieved better fuel mileage and emission reduction while giving out a performance similar to a V8 gas engine.

Like the recently released GS 350, Toyota reworked the chassis of the GS 450h which improved the driving dynamics of the car with technologies like DRS or Dynamic Rear Steering and AVS or Active Variable Suspension.

The interior of the car makes use of different interfaces for the driver for safety, alertness, and comfortable ride.

Lexus also makes use of the Dynamic Handling System for the GS 450h that intergrates the DRS, AVS, steering with variable gear-ratio, and VDIM or Vehicle Dynamics Integrated Management. Buyers will also benefit from the LKA or Lane Keep Assist, blind spot monitor, a head up display, Night View, and pre-crash safety technology.

The GS 450H 2010 model still sports the hybrid motor in combo with the V6 3.5L engine capable of giving out 340 horsepower. The fuel mileage is excellent with 25 mpg while on the highway and 22 mpg during city driving.

The new GS 450h gets some fine tuning for its exterior design lines and gives some color options available for car buyers. Lexus also injects some interior trim updates. Safety features like the Pre-Crash system also gets some tweaking. The navigation and entertainment system also received some upgrades.

The exterior aesthetics are not really that major. The designers changed the front grille and put emphasis on the hybrid blue logo. The tail lights are also now covered with clear lenses. The SE-L line has an option for an 18-inch alloy rim. The insides get a Venaro Grey leather treatment while the start-stop button gets the blue backlight to be consistent with the hybrid color concept.

The Pre-Crash system now makes the seatbelts tighter prior to an impending crash while the car implores brake assist to somehow slow the car down before a collision. Whiplash protection is also enhanced with the new headrests equipped with inflators.

The navigation upgrades includes a 40 Gigabyte hard drive that can store the navigation files and also store music for the entertainment system. Consumers can either opt for a 10-speaker set up of Lexus Premium or go for the Mark Levinson 14-speaker surround sound with USB, aux, and Bluetooth capabilities standard to both.

The sticker price for the new Lexus release is expected to stay close with the 2009 model at $56,550.
