In the RX 450h, Lexus has developed a whole new class of vehicle. Since the RX became the world's first luxury SUV in 1998 we have been taking the generous spaciousness and body strength of a traditional SUV and allying it with aerodynamic, sporty styling. And then raising the bar even further with exhilarating power, astonishing fuel economy and luxurious levels of detail and comfort. At the heart of the RX 450h is an advanced full hybrid engine. It combines two high output electric motors with a potent, 3.5-litre V6 super-efficient Atkinson Cycle petrol engine. On the open road, you'll discover a breathtakingly smooth acceleration that switches seamlessly between economical electric and surging petrol power. Performance and agility have been honed to perfection on the famous Nürburgring racetrack in Germany, yet the RX remains sturdy and reliable in off-road conditions too - with advanced All Wheel Drive maintaining traction in the most difficult terrain.
