At the moment Lexus are working on the RX Facelift and this new model will be on the market later on in the year. Even though it is a mid-cycle refresh, it had been claimed that the RX Facelift will include a great deal of upgrades.
To begin with, the future RX350 and RX450 will have a whole new appearance. On a more important note, the RX Facelift will be able to perform on a much better level than what the current RX models are able to offer us.
The reason for this is that the RX Facelift is made with aluminium. Lexus have clearly stated that they have brought the weight of the RX Facelift down by using aluminium. Due to the weight of the vehicle being less, the care will be more optimized for power and be more fuel efficient.
Lexus have obviously not given us any performance figures for the RX Facelift yet. There will be more information on that in the near future when Lexus launches the finished RX Facelift at some point over the next few months.
