RX 350 – European Premiere
On sale throughout Europe in April 2006, the Lexus RX 350 further refines
driving pleasure through the class-leading performance of a new 3.5 litre V6
petrol powerplant. Equipped with an ultra-smooth, 5-speed automatic
transmission, this outstanding powertrain offers increased power and torque of
203 kW/276 DIN hp at 6,200 rpm and 342 Nm at 4,700rpm whilst reducing
fuel consumption by some 8% over the previous RX 300.
Enhanced Noise Vibration and Harshness measures result in even further
reduction in noise levels at all vehicle speeds, whilst the new luxury SUV also
features a new Mark Levinson Premium audio system, as well as a new, highdefinition
and fast response Lexus Navigation System.
