Infiniti has revealed that the new Q50L is its first car to developed exclusively for the Chinese market. It will also be the first Infiniti to be built in China.

Although based on the existing Q50 executive sedan, Infiniti claims that the L is a result of "listening closely to customers' needs" in what it describes as a highly sophisticated market.

The first obvious difference is the car's length. Affluent Chinese drivers value rear passenger space as highly as performance or exclusivity. The Q50L measures 4.8 metres from end to end, and its wheelbase is also greater, at 2.9 rather than 2.8 metres.

But in addition to getting more leg room, passengers will also get mood lighting and rear window sunshades as standard, as well as a 14-speaker Bose sound system.

Infiniti hasn't neglected the driver either; the car will come with a host of electronic aids including active lane control.

The Q50L will also be the first Infiniti to benefit from a new economical but potent 2-litre, four-cylinder turbocharged engine and a drive-by-wire electronic steering set-up for smoother and more responsive maneuvering.

It also seems that Chinese automotive predilections are gaining traction in other countries. The Q50L's big brother, the Q70, is already offered in a longer 'L' variant in China -- and the model is now going to go on sale in the U.S. and Canada.
