Lexus to sell only 10 of its new GS450h saloons per month, but it is still a vehicle.

That’s because it is the first luxury car to go into employing a petrol-electric hybrid Yes, parent Toyota sells the Prius here fundamentally the same system, but a small car with a large-car

At $121,990, the GS450h is hardly but it undercuts the Lexus GS430 V8 by It also comes even equipped, adding rear-guide for the rear-view camera, MP3/WMA to the superb Mark Levinson and DVD video and audio to an already standard equipment list.

In some markets the 450h is expensive than the V8, but Lexus in has taken a conscious decision to hybrid as a significant difference and compared to its rivals. With tipped to pass $1.50 a and two more hybrids (the crossover and LS600h luxury arriving by April next this looks like a strategy.

But not half as clever as the Synergy Drive (HSD) that makes all this

In essence, electricity generated by the engine or converted from energy created by the braking is stored in a nickel metal (NiMH) battery and used to the car along with the petrol Sometimes the car is only petrol-driven, or solely on electricity. Sometimes it both simultaneously.

Where the GS450h breaks new is by mating HSD to a longitudinally mounted V6 petrol engine and rear-wheel The adaptation is brilliant in itself, two generators and planetary gearsets in the transmission tunnel where a six-speed auto is found in all GS models.

As a result, the GS450h better fuel economy, and straightline performance than more expensive rivals larger petrol engines including Lexus’ own GS430.

It is the aspect that Lexus is and no wonder. Independent results the 450h is quicker than the V8 in and rolling acceleration tests. a low 6.0 sec 0-100 km/h time it into rarefied company.

Add an 7.9 L/100 km fuel claim and the has few rivals. Our testing produced a 9.2 L/100 km average, but that is far ahead of most large-capacity luxury saloons.

Then there’s the environmental which naturally benefits lower fuel consumption. The emits 30 grams less of changing carbon-dioxide per kilometre the GS430 V8.

The GS450h’s technology restricted to the transmission. The all-alloy V6 combines traditional port and direct injection, running on or both depending on load

The hybrid combination produces a eerie experience, something by the use of a continuously variable transmission means step-free linear At idle, ultra-low speeds and in only the electric motor the car. But the petrol engine is so that it is hard to tell it kicks in.

Only when revs high in the range does and exhaust noise become more than a background We can’t say at what point in the rev that occurs, as the GS450h a traditional tachometer for a power measured in kilowatts.

In fact, the measurement of outputs is a somewhat business. The V6 makes 218 kW, the motor 147 kW. But combined they never 254 kW.

The petrol engine makes 368 Nm of and that is also the maximum figure. But while that in at 4800 rpm, the motor peak 275 Nm is available from revs.

And this is where the feels most different to petrol-engine luxury cars. Its and low-speed acceleration is outstanding, it brilliant for the cut and thrust of city overtaking and conquering the steepest

It’s also great for out of corners on your favourite road. But the traditional Lexus to include steering feel and authority means the earlier of the curve aren’t so enjoyable.

The employs the same over-arching of electronic handling aids as the Known as VDIM (Vehicle Integrated Management), they traction, stability and steering that are non-switchable. They are too intrusive, making flowing difficult.

Similarly, the sports for the active dampers is too aggressive for all but the roads.

What the GS450h enjoys is long-legged cruising, ensconcing its in its high-tech cabin. That is all of the usual GS experience, as is the tight leg and head-room.

It’s only a car in a straight line but it is a technical that points to our automotive Outstanding value makes it compelling.
