suspension. In 2006, Nissan renamed the 160 SR to the Sport SR in line with name changes across the board for the K12. However, this rebranding was short-lived: the performance model reverted to the 160 SR name in late 2007. The launch of the 160 SR coincided with a revision of the K12. The radiator grilles were given a chrome strip through the centre and the original amber indicators were replaced with clear ones. The rear bumper was restyled and made more robust (apparently in response to French parking habits). The interior was also given a makeover, with more supportive seats, thicker glass and better soundproofing. There were originally six trim levels of the K12, but in 2006 they were simplified to just three: Initia, Spirita and Sport. In addition, the launch line-up of six engines was reduced to the most popular four. The vehicle was unveiled at the 2005 Frankfurt Motor Show. Micra K12C (2007–2010) In late 2007, the Nissan Micra was facelifted again. It had several cosmetic tweaks: every model featured the standard racing grille taken from the K12 160 SR; the front headlights were tidied up (incorporating light blue-tinted sidelights) and the grilles housing the indicators were edged in chrome. Inside, there were new seat fabric designs, and the dashboard featured parts taken from other Nissans. New equipment included an audible speed warning, bluetooth connectivity with the vehicle and reversing sensors. All models (save for entry-level) were fitted with sport bumpers and spoilers on the sides and rear. Larger wing mirrors were also added on some models. The 1.2-litre engine for the entry-level Visia was a unit, as opposed to the version on other grades. In addition, the Visia did not have the option of a 1.4 L engine. The 1.6 L engine was reserved for the 160 SR and as an option on the Active Luxury grade. Starting from 2007, Nissan began selling the K12 in Australia. Imported from Japan, all were five-door hatchbacks, with the 1.4-litre petrol engine and automatic transmission. The only factory option was the City Collection pack, which included an upgraded six-disc sound system, six-spoke alloy wheels, and side and curtain airbags. The Australian specification adopted the Japanese facelift, with indicators integrated into the headlamps. In 2009, it was reported that a total of 31,600 units were sold in Japan and nearly 122,000 worldwide. Fourth generation (K13; 2010) The first sketches of
