A video has been released teasing the new Infiniti Q50 which will be previewed at the Detroit motor show later this month.

Few details are forthcoming about the replacement for the G-series saloon, but according to Infiniti design boss, Shiro Nakamura, the Q50 will be “much sportier and more dynamic than the current car”.

Infiniti’s teaser video shows a heavily sculpted headlight, which closely resembles that of the Infiniti LE concept unveiled at last year’s New York motor show.

That model is pitched as an upscale version of the Nissan LEAF, but the Q50 will rival the BMW 3-series and Audi A4. Infiniti previously promised the Q50 will be offered with Mercedes-sourced four-cylinder petrol and diesel engines.

The Q50 will be the first new model to carry Infiniti's new naming structure, which aims to give more clarity to its model ranges.

After the Infiniti Q50 is previewed in Detroit, it will make its European debut at the Geneva motor show before going on sale in the autumn.
