No, as I recall the reservation form said expected delivery would be in the spring. It was in the Christmas catalog from NM, maybe thats what got you confused.

Making its European debut at the 2005 Frankfurt Motor Show, the new Lexus GS 450h luxury sports sedan follows the RX 400h SUV as the second production vehicle to introduce the technical sophistication and high-performance attributes of Lexus hybrid drive engineering to the premium automotive segment.

On sale throughout Europe from the spring of 2006, the new GS 450h further reinforces the importance of hybrid drive systems as the core powertrain technology for the Lexus luxury marque. Its new hybrid drive-train encapsulates precisely the type of driving characteristics that are the hallmark of Lexus drive-train engineering; smooth, powerful and refined, yet offering a highly engaging and rewarding driving experience.

The Lexus GS 450h is the world's first hybrid luxury sedan to combine front engine mounting with the rear wheel drive essential to sports driving dynamics.

The latest hybrid petrol/electric powered addition to the luxury Lexus range is named "450" not to indicate the cubic capacity of the engine but, rather, in recognition of a power output comparable to that of a conventional 4.5 litre, V8 petrol engine, whilst the 'h' suffix indicates the presence of Lexus' highly sophisticated hybrid drive system.

POWERTRAIN

Displaying similar operational characteristics to the RX 400h's Hybrid Synergy Drive®‚ system, a completely new, front engine, rear-wheel drive Lexus hybrid powertrain has been engineered for the GS 450h.

It features an ultra smooth running, 3.5 litre D-4S direct injection V6 petrol engine generating over 210kW/286 DIN hp mated to a high-output, permanent magnet electric motor developing over 140kW/190 DIN hp, driving the rear wheels both independently and in tandem, as appropriate. The system produces a total power output of more than 250kW / 340 DIN hp.

The petrol engine combines a new D-4S fuel injection system with high strength chain drive and roller rockers, and high torsional stiffness connecting rods. New, double slit, fan-shaped spray injectors optimise the fuel/air gas mixture formation for maximum combustion efficiency, generating higher rpm and power output with minimal emissions. The new D-4S syst***s combination of direct and port injection realises optimum engine efficiency throughout the power band. Direct injection improves full-power engine performance, whilst both low-power engine fuel economy and emissions reduction are enhanced through the coalition of direct and port injection systems.

In addition to the petrol engine, the new GS 450h Hybrid Synergy Drive®‚ system comprises a power control unit, a high performance nickel-metal hydride battery and a power transmission unit.

The power transmission unit consists of an electric motor, a generator, a power split device and motor-speed reduction gears. Via planetary reduction gears, the power split device combines and re-allocates power from the engine, electric motor and generator according to operational requirements. As in the RX 400h, these system components are all housed in one lightweight, highly compact transmission casing.

Unique to the GS 450h, however, the new hybrid transmission system now incorporates two-stage motor speed reduction gearing. Through the new luxury sedan's seamless, continuously variable automatic transmission, the twin stage gearing generates maximum low-gear torque for significantly enhanced acceleration, as well as extended high-gear performance for quiet, high speed cruising with improved fuel efficiency in almost all driving conditions.

Via a centre console mounted switch, the new hybrid transmission also offers a choice of three power settings; "Normal", for the optimum balance of power and traction, "Power", for maximum acceleration, and "Snow", for excellent traction control under the most slippery road conditions. Moreover, with the "Sport" manual gear change mode selected, each of the 6 sequential "steps" in gearing incorporates engine brake force in the manner of a conventional transmission, improving vehicle control and further enhancing the GS 450h's high performance sports driving experience.

HYBRID SYNERGY DRIVE® IN OPERATION

Over the course of any journey, the new hybrid drive system operates in several different modes to maximise the GS 450h's overall efficiency: At rest, the engine stops automatically to conserve fuel. Under operating conditions of low engine efficiency such as start up and low to mid-range speeds, the vehicle runs on the electric motor alone, thus eradicating CO2 emissions and providing exceptionally quiet operation. Under normal driving conditions, engine power is divided by the power split device to both drive the wheels directly and power the generator which, in turn, drives the electric motor.
In these circumstances, power allocation is constantly monitored and adjusted between engine and motor to maximise efficiency. When sudden acceleration is required, engine and electric motor again operate in tandem, with extra power supplied from the battery to boost motor response.

During deceleration and under braking, the engine switches off and the electric motor acts as a high-output generator. This regenerative braking system optimises energy management in the new GS 450h's Hybrid Synergy Drive® system by recovering kinetic energy (normally wasted as heat under braking and deceleration) as electrical energy for storage in the high performance battery. Furthermore, battery power level is constantly managed via the engine driven generator to obviate any requirement to recharge the system from an external source.

PERFORMANCE

The new powertrain equips the Lexus luxury hybrid sedan with performance characteristics on a par with conventional 4.5 litre V8 engined models.
Combined power output is over 250kW / 340 DIN hp, and the new GS 450h will accelerate seamlessly from 0-100kph in less than 6.0 seconds, the Lexus hybrid transmission system eradicating the expected 'jumps' between gears of a conventional drive-train.

Equally impressive is the potent mid-range torque afforded by the syst***s powerful electric motor.
Operating in tandem with the V6 petrol engine, it is capable of delivering maximum torque instantaneously, and seamlessly, upon demand. This characteristic is most beneficial in mid-range acceleration during overtaking manoeuvres, and the Lexus GS 450h will accelerate from 80 to 120kph in under 5 seconds.

Conversely, the GS 450h also proves substantially more frugal than comparable sports sedans, returning combined fuel economy figures on a par with those of a 4-cylinder 2.0 litre engined vehicle. Moreover, already compliant with EURO IV emissions standards and rated SULEV (Super Ultra Low Emission Vehicle) in the USA, the new Lexus returns CO2 emissions of under 195g/km; markedly less than rival, premium sector sedans with similar engine power.

SAFETY

The new GS 450h is equipped with a class-leading range of active and passive safety systems, including the second generation of Lexus' state-of-the-art Vehicle Dynamics Integrated Management (VDIM) system, to enhance performance, traction control and vehicle stability (For more information about VDIM, please also read section 5: 'Lexus Safety Technology')

Lexus unveils the 2007 GS 450h at the Montreal International Auto Show


The world's first luxury hybrid sedan combines performance, power and
style


TORONTO, Jan. 19 /CNW/ - Lexus today gave Canadian drivers their first
look at the next generation in luxury cars, unveiling the all-new 2007 Lexus
GS 450h hybrid luxury sedan at the Montreal International Auto Show.
"The GS 450h is the world's first passenger car that combines luxury
features with hybrid power, performance and fuel efficiency," explained Stuart
Payne, Director for Lexus in Canada. "It's also the first full-hybrid in the
world to feature a front engine and rear wheel drive. As such, the GS 450h is
a ground-breaking vehicle, representing the next generation of luxury sedans."
Lexus has incorporated many performance, styling and safety features into
the 2007 GS 450h.

Power
The GS 450h features the Hybrid Synergy Drive (HSD) powertrain. It
includes a 3.5-litre V6 engine and high torque electric motor that combine to
deliver 335 horsepower at 6,200 rpm - for performance equivalent to a
4.5-litre V8.
This system is engaged through the Lexus Electronic Throttle
Control System with intelligence (ETCS-i), and delivers power to the
P245/40R18 performance summer radials mounted on unique 18-inch alloys via an
Electronically-controlled Continuously Variable Transmission (ECVT). The V6
gasoline engine also features Lexus' innovative combined direct and port fuel
injection. The overall result is quick yet smooth acceleration from 0-100 km/h
in less than six seconds, with compact sedan fuel economy and a Super Ultra
Low Emissions Vehicle (SULEV) emissions rating.

Performance
The GS 450h is fully equipped with systems that enable the driver to
harness and direct its hybrid power to push the vehicle to its performance
limits with confidence. The electric power steering features variable gear
ratio steering, while the Anti-lock Braking System (ABS) includes electronic
brake force distribution and brake assist. Both are enhanced through the Lexus
Vehicle Dynamics Integrated Management (VDIM) system, which automatically
makes subtle adjustments to steering and acceleration to enable the driver to
push the GS 450h to its performance limits without losing control. The GS 450h
is also equipped with Vehicle Stability Control (VSC), Hill-start Assist
Control (HAC) and Traction Control (TRAC), while the independent, double
wishbone front suspension and multi-link control arm rear suspension both
feature active height control systems and stabilizers for the ultimate in
performance and handling.

Safety
In addition to VDIM, VSC and other control systems, the GS 450h is fully
equipped with active and passive safety features, including high intensity
discharge headlamps with automatic light control system, auto levelling
headlamp system, headlamp washers, and fog lamps, dual-stage airbag
supplemental restraint systems (SRS) plus knee airbags for both driver and
front passenger, plus front and rear seat side airbags and head/side curtain
airbags. All positions have three-point lap and shoulder belts with
pretensioners and force limiters, and the GS 450h includes anchor points for
child restraint seats, child protector rear door locks, and a factory
installed first aid kit and tool kit.

Comfort and convenience features
The Lexus GS 450h is fully-loaded with standard features that make it a
joy to own and drive. These include, but are not limited to: a 14-speaker Mark
Levinson audio system with AM/FM/cassette and compact disc DVD autochanger and
steering wheel controls; a DVD-based navigation system with back-up camera;
Bluetooth compatibility; power telescoping steering wheel with auto tilt and
memory; power windows with auto up/down function for all positions; power door
locks with smart-key entry system and key lockout protection; push button
start; cruise control; power moonroof; power rear sunshade; dual illuminated
vanity mirrors; built-in garage door opener; and accessory power outlets.

Style
The GS 450h wraps performance, safety and comfort in the L-Finesse style
that is unmistakably Lexus. From its sculpted form, clean exterior lines,
aluminum alloy wheels and power moonroof, to its wood and leather interior
trim, welcoming interior lighting, and attention to detail, the GS 450h sets
new standards for style and luxury.
"The GS 450h joins our very popular RX 400h luxury hybrid SUV to bring
the benefits of hybrid power and efficiency to all Canadian luxury vehicle
buyers, whatever their needs", Payne concluded. "We're the first luxury
automobile company to do this, and only Lexus can offer both a hybrid luxury
car and SUV for environmentally conscious consumers to choose from, without
sacrificing luxury refinements or performance."
The 2007 GS 450h will go on sale in Canada in April. Pricing details will
be released closer to the on-sale date.

Well, this is interesting. I thought that it was suppose to have OVER 340hp?? This is the first time I have saw 335. Interesting...

Montreal Auto Show: 2007 Lexus GS450h
by Mathieu St-Pierre , Auto123.com

2007 Lexus GS450h

No manufacturer is more committed to bringing Hybrid vehicles to the mass market than Toyota. To prove this point, Lexus is officially launching their newest addition to their fleet of green vehicles: the GS450h.

Combining Toyota's Hybrid Synergy Drive and the 3.5L V6 from the GS and IS 350, output is rated at 335 hp and 320 lb/ft of torque. This is in fact the first production RWD hybrid. The transmission is of the continuously variable type (CVT).

As with other Hybrids, fuel consumption is low (estimated average of 8.5L /100 km) and performance is high. Lexus expects the big sedan to reach 100 km/h in less than 6 seconds.

Now, if you think this is impressive, wait until you get a closer look at the LS600h hybrid. Rumour has it that it might put out around 500 hp.

---------------------------------------------------------------------------------------------------------------------------------

Sounds like it may perform closer to the GS430 than the future GS460(assuming approx.370-380 hp/torque.) . . . . . . .

Sigh, looks like that_guy is right and I am wrong in our predictions after all. I can't believe how much the gas motor has to be detuned in order to be clean and frugal enough for use in a hybrid. And I thought the GS450h is supposed to be a performance hybrid? Hopefully the LS600hL will finally demostrate the true performance potential of a hybrid drivetrain. And can we say a GS600h later on?
