More details of Infiniti G37 Convertible
Prices haven't been announced yet, but two trims (GT and GT Premium) have been confirmed.
Both come lavishly equipped: GT models get 19-inch alloy wheels, a wind deflector, leather upholstery, xenon active cornering headlamps and electrically adjustable heated front seats.
There's also a sophisticated entertainment system that includes a CD player, 2GB hard drive to store music files, a USB MP3 player input, Bluetooth with voice controls and a rear-view camera.
Inifiniti's 'self-healing' Scratch Shield Paint, which repairs minor scratches using an elastic resin that flows back into shape after being damaged, also comes as standard.
Upgrading to GT Premium adds a 30GB satellite-navigation system with a 10GB music capacity, front seats that can be cooled as well as heated and an upgraded stereo system.
Both versions use a 316bhp, 3.7-litre V6 petrol engine that gives a 0-62mph time of 6.2 seconds.
