Lexus RX400h

Good (but not exceptional) economy Good response and Well built Can torque Good interior design

Toyota chose to capitalise on its technology by releasing hybrid models, many including us it simply represented a devaluation of the

After all, the groundbreaking easily the world’s best-selling and one of the most important cars released uses a petrol-electric clothed in a highly efficient, packaged body. But cars the RX400h are (in relative terms) lumbering, un-aerodynamic and heavy. So why put a driveline in a car like that?

having now experienced the RX400h, we can see where Toyota is coming Yes in absolute terms the fuel remains unscintillating although for class of car it’s good but the way engineers have taken of the opportunities that the hybrid allows has made for a very vehicle.

So let’s take a at the AUD$97,545 RX400h.

Despite due for replacement (which incidentally you currently should be able to an excellent new car price reduction), the still looks quite The proportions and detailing are good; the only angle where the car a little odd is from directly Build quality is right up to the high standard of all Lexus with the doors shutting equal width panel and excellent presswork of the body

Under the bonnet you’ll as is the case with lots of these days a series of dress covers. But delve and there’s a 3MZ-FE 3.3 litre V6 petrol engine that 155kW at a relatively low 5600 Peak torque is 288Nm at rpm.

The electric power is by no less than three motor/generators. As is the case with all hybrids, two of the motors are contained the ‘transmission’ casing, but the other motor is positioned at the back of the driving the rear wheels. In all rear-wheel drive is provided by electric motor alone is no mechanical driveshaft connection the front to the back.

The front power output is a considerable at 4500 rpm, while a 333Nm is also available. At the max power is a much lower Combine all these outputs and quote a maximum of 200kW of the way the power outputs are linked, you just arithmetically add the numbers).

The electric and petrol powers are combined by the very sophisticated system. Driving is two-pedal style. The car starts moving on power and then the petrol kicks in. However, as you move the petrol motor might be on or the electric assist might be or not occurring, and regenerative braking be operating or braking might be by the discs.

The central LCD can be configured to all these power flows, but in the driver doesn’t need to even a single decision as to is occurring.

In fact, that’s a of the system other than the Park, Reverse, Neutral and positions, the only manual over-ride available is a ‘B’ mode which, incidentally, is not effective. The all-wheel drive is not driver-configurable – this a car for someone who wants an involving

So how does all this driveline come together? Generally, well.

Because the RX400h is a front-wheel drive car with low power rear-wheel assist, the drive system feels a different on the road to a traditional drive car. That’s not to say the drive system is for show up a very steep, wet driveway would have caused problems to a front-wheel drive, the used all wheels to gain and easily climbed the slope. probably a pretty good application of the system use on roads slippery by rain, mud or snow, than being driven off the track.

Push the car hard and the front-wheel system can torque steer, the and weight of the electric-assist steering markedly. Point-and-squirt in urban, wet conditions and a firm hand to be kept on the steering. With the of the excellent stability control, it be hard to get into trouble but this isn’t a car that unfussed no matter what the and driving style.

In more use eg on country roads – the is very good and the grip are high.

Power and response are excellent. One of the advantages of hybrids is the availability of electric motor and this can be felt in the 400h. Put foot down and the car lunges as if it has a much larger engine just 3.3 litres to haul the 2 tonnes.

So it goes well but of the fuel economy? The official is 8.1 litres/100km and on test over a variety of conditions, we got 10.4 Despite the protestations of Lexus, we think that is a sufficiently improvement over the many cars also available in class.

In fact, we’d go further and that the RX400h is not a good buy if concerned only with economy.

But as an overall package, the works very well. The level is high, with steering HID headlights, high sound system with DVD capability on the colour LCD, (and heated) seats for the driver and passenger (two on the driver’s seat), and all three vision mirrors having an function. There are airbags driver and front passenger, knee, front side and curtain and the brother RX330 has a crash testing result.

The seats are comfortable and have armrests. Pop-out door are provided and the glovebox is large. the reach and height electrically steering column and a good position is easily found.

The and controls are superbly clear.

But are two shortcomings in the way the equipment works.

that fitted to other models, the navigation system is The voice instructions are repetitious and contradictory (an actual example: freeway is on the left” followed pause by “The freeway is on the the interface is not intuitive and prevents the of any data (even by the passenger) the car is moving; and the navigation system can be slow to react.

The other deficiency is the cruise on hilly country roads, its regulation is terrible. In fact, the feels like it hasn’t recalibrated for the hybrid driveline.

The seat has good but not fantastic Kneeroom is fine but space for the is a little tight, and the very will have insufficient Rear passengers are provided door pockets and reading

The rear seat folds on a basis, with the ‘20’ the centre section. This the carrying of two rear seat while still allowing loads to be fitted in. When the seat backs lock into place.

In addition to (nearly) flat, the rear backrests can be individually adjusted for angle.

Moving further the back door can be remotely by the key fob. Despite initial we found that in practice works very well. An use: a mother carrying a and wanting to load some needs just press the button to see the door slowly in front of her.

Talking of children, the child anchorages are located on the back of the seat (so the straps don’t into the load space) and the doors and high seats placing children in the rear an task.

Rear load is fine for this type of The cargo blind can be set to automatically when the rear door is and beneath the floor are two normally storage compartments. Two rear area lights are fitted and a 12V outlet. The spare wheel is the car.

A warning triangle, aid kit and valet pack are provided. tie-down hooks finish off the equipped and designed rear.

So to make of this car?

You buy the RX400h solely for its fuel or performance, or handling, or equipment, or design. But taken as a package, the adds up to a car that is greater the sum of its parts.
