First drive: Lexus RX 450h

Lexus

Lexus has always been proud of its big four-wheel-drive, the RX. With this latest model, Lexus is trying to improve most on the areas that are most in the limelight at the moment – economy and emissions. Shunning diesel engines yet again, the RX uses a tried-and-tested petrol hybrid layout to try and get the very best economy figures. Has it worked? AOL Cars heads to Lisbon to find out.

What is it?

The Lexus RX was one of the very first hybrid four-wheel-drive cars, and set the pace for other manufacturers to follow suit. With each incarnation, it has grown in stature and quality. This latest model hopes to offer even greater economy, along with better interior quality and the ability to take the fight to its rivals. With more and more companies investing in and producing hybrid electric models, the RX doesn't have the market to itself anymore – which means it has to be better than ever to get to the top.
