Lexus GS 450h Hybrid Specifications

If you're looking for a luxury fuel-efficient vehicle, check out the Lexus GS 450h Hybrid. The Lexus Hybrid features a dual VVT-i (Variable Valve Timing with intelligence) system. This Lexus GS system is also equipped with dual fuel-injection.

Lexus GS 450h delivers optimum power through the dual VVT-i. Basically, the system continuously monitors the engine's speed and load. It is designed to respond quickly by adjusting the intake and exhaust valve timing system. It delivers the Hybrid with optimum power and efficiency at any speed.

The base price for the Lexus GS Hybrid is $56,550 and can achieve up to 25 MPG (miles per gallon). However, keep in mind that this car has a 3.5-liter V6 engine. This is a very powerful engine for a Hybrid automobile. This car will deliver powerful acceleration, but keep in mind that the VVT-i system is designed to control fuel efficiency, so that gas consumption isn't wasted.

For example, if you floor the gas pedal, the GS Hybrid will respond with your instruction and deliver immediate power. However, the VVT-i system will monitor the fuel intake in an effort to save gas. If you floor the pedal a second time, you might not get the same response as you did the first time. This is actually a good system because there are driving conditions where you need optimal power. One case is when you are entering a highway and need the extra pickup.

In addition to optimal power and fuel efficiency, The Lexus 450h features a continuously variable transmission, which allows the engine to operate at peak efficiency and houses the electric motors of the Hybrid Drive system. It receives power from both the engine and battery to power the rear wheels. It doesn't contain any gears like a traditional transmission so that shift shock is eliminated for smoother acceleration.

The Lexus Hybrid also includes Regenerative Braking. This technology is used to capture lost energy from heat during braking. The energy is captured and used to recharge the battery for the electric motor.

Another great feature is the electronic system that adjusts the steering response. This system is called VGRS (Variable Gear-Ratio Steering) which optimizes the steering-gear ratio for certain driving conditions. It will provide easier low-speed maneuvering and increased high-speed responsiveness and stability. It also works in conjunction with the VDIM (Vehicle Dynamics Integrated Management) system.

The Lexus GS 450h dual exhaust system is designed to allow the gasoline engine to breathe easier resulting in better efficiency and improved performance. The car also has rear-wheel drive, which is the first Hybrid to be driven by the rear wheels. The unique rear-drive powertrain works great with the advanced suspension system.

The advanced suspension system offers you the choice between a Normal or Sport setting. The system automatically senses the character of the road and constantly monitors your steering and braking movements, then adjusts the suspension damping to maintain your selected comfort level. The Lexus GS 450h Hybrid has a premium price tag, but it is loaded with several innovations to improve your gas mileage.
