Seven-seat RX coming?

Bigger is better at Lexus. Our exclusive picture shows that the next RX will be larger than the current model – and it could even be offered as a seven-seater for the first time.

Despite this, the Japanese firm is likely to take a conservative approach to the newcomer’s styling. It will feature swept-back headlamps and the trademark Lexus grille, while the distinctive curved roof of the existing car will also be retained. Our spy shot (below) shows that the replacement’s underpinnings are already being fine-tuned in a test mule wearing the current SUV’s body.

At first glance, it looks like any other RX, but close inspection reveals that the rear lights no longer sit flush with the bodywork. That’s because the panels have been widened to account for the new platform’s bigger dimensions. This added size could pave the way for an optional third row of seats, which would put the Lexus up against BMW’s X5 when it arrives in dealers in 2009.

The new 4x4 likely to debut at that year’s Tokyo Motor Show because, although the biggest market for the RX is the US, the model will be the first SUV in Japan to wear a Lexus badge. The current generation is called the Toyota Harrier in its home market.
