Lexus RX-400h Hybrid 4X4


Click here to write a review about the Lexus RX400h


The Lexus RX 400h is billed as the first hybrid performance SUV. It combines a 3.3-litre V6 petrol engine with two electric motors and a clever E-Four system to drive the vehicle.  The petrol engine and motors can work independently of each other or in synergy such as under hard acceleration to produce the cars great performance statistics.  The electric motor is used to pull away and at low speeds when the petrol engine is least efficient and therefore it emits no harmful emissions.  It is charged by regenerative braking and while the car is cruising.



The petrol engine produces 208bhp, while the electric motors produce 123kw in the front and 50kw for the rear.  Combined total peak output is 269bhp. Due to the electric motors high torque the RX 400h can accelerate to 62mph in 7.6 seconds and take the car to 124mph.

The electric motors can power the car independently up to 50km/h without the aid of the petrol engine.  They also allow the car to switch off while stationary such as at traffic light.  All these help the environmental credentials for this 4x4 which are so often criticised by government and environmental organisations.  Mayor Ken Livingstone even review the exemptions made to the London congestion charge after learning that the Lexus RX400h hybrid SUV did not have to pay.  However 34.9mpg combined and CO2 emissions of 192g/km are the best in class when compared against other luxury SUVs.

Starting at 36,393, it is priced competitively plus is technologically advanced.  Technology appearing in the RX 400h is its highly efficient Electronic Continuously Variable Transmission system (E-CVT) and E-Four system which controls the four-wheel-drive system which allows the car to be driven through the front wheels only for maximum efficiency and through all four wheels when required such as at high speeds.


Lexus has an excellent reputation for reliability and quality.  Much of its hybrid technology has been tested through the Toyota Prius.  If you are still unsure, the battery and hybrid system is covered by a 5 year warrant for peace of mind and is relatively maintenance free due to the lack of moving parts.  There is a choice of SE models and a range topping SE-L model also available.

RX400h:  I have to date had 6 of these as my company car, the latest with the aesthetically pleasing woodpack which from my viewpoint gives the final touch to this classy top range vehicle.  I have now purchased the exact same model for "er indoors".  We were originally looking at a Toyota Rav4, but with the efficiencies that can be gained from driving this superb hybrid vehicle carefully it probably gets the same economies as the much lesser classed Rav4, yes OK it was much more expensive!  For those of you that drive into London you also pay NO congestion charge.
The performance of the car is absolutely awesome for a 2 tonne motor, 0-60 not much more than the top of the range Celica's I use to drive.
Lexus is very much a cut above Mercedes in both reliability and level of kit as standard.  After driving these "hybrid" vehicles since they were launched I can confirm that their reliability is superb. My only complaint is that although my SE comes with a reversing camera, they don't have parking sensors and in darkness the bulbs in the reversing lights are not bright enough to provide good rear vision.  All in all the RX400h is brilliant and worth every penny!

400h: Fantastic. The most exciting car I have ever owned and these have ranged from SL's to 911's and DB9's.
