Ford's sixth-generation Mustang has broken cover a day before it will be officially revealed.
The blue oval's simultaneous gala reveals of the new Mustang have been spoilt by a Detroit-based Magazine.
An Autoweek cover spread featuring the new coupe has been leaked across the web just a day before Ford shows off the Mustang at events in the US, China, Spain, Great Britain and Australia.
Ford has cloaked a new Mustang in secrecy ahead of its unveiling tonight (NZ time).
The finished car appears quite similar to computer illustrations that made their way around the web in October.
Differences include a purposefully sculpted bonnet similar to the unit used on V8 models by Ford Performance Vehicles.
A brightly coloured, aggressively-shaped rear diffuser also comes as a surprise.
Tonight's unveiling event can be viewed live at www.gofurtherlive.com.
Ford says it will also reveal two new vehicles and new technologies to a select audience of about 2500 dealers, employees and media at the Forum and CCIB arena. Tens of thousands of others are expected to watch the ''Go Further'' event live online.
The Ford Mustang is about to become the newest member of a very exclusive club – vehicles in continuous production for 50 years. In its first 49 years of production, Mustang has gained a worldwide base of avid fans, including more than 5 million on Facebook, the most of any vehicle nameplate.
The new Mustang will reach showrooms in the US next year, with right hand drive markets taking the car some time later.
It is expected that like the Mustang II and Mustang III there will be a turbocharged four-cylinder entry-point engine. It's likely to be an upgraded EcoBoost unit of 2.3-litres, which will start a line up of engines that will includes V6 EcoBoost units and the 5.0-litre Coyote V8 in both blown and unblown versions.
The car will also feature independent rear suspension; a first for Mustangs and judging by the photograph, evolotionary styling rather than a sea-change.
Ford has launched ''Mustang Countdown,'' an online video series to throw the spotlight on the new car and the culture that has formed around it across the globe, and it leads up to the 50th birthday of the original car on April 17, next year.
More than 9.2 million Ford Mustangs have been sold since the car’s 1964 debut and the car has made more than 3000 appearances on film and TV – including Bullitt (1968), Gone in 60 Seconds (1974 and 2000), I Am Legend (2007) and Drive (2011). In 2014, a modified Mustang will become the hero car in Need for Speed, based on the long-running video game series from Electronic Arts.
