A last minute addition to our list of automotive-goodness to watch out for when the Detroit Motor Show kicks-off tomorrow – this time from Hyundai. The Korean automaker will rip the covers off its HCD-12 Curb Concept as well as presenting the world debut of its 2012 Veloster sports coupe, a vehicle that's immediately notable for it's three forward-hinged doors (two on the passenger side, one on the driver’s side).

Apart from these teaser pics, there is basically zero detail on the HCD-12 Curb concept vehicle ... but we have less than 24 hours to wait before all is revealed.

Veloster

There is (slightly) more detail on what to expect from the Veloster. The vehicle first appeared as a (two-door) concept back in 2007 and it looks to have retained some of the styling – at least from the front.

Apart from the unusual door configuration, the pic so far released indicates a split rear glass hatch at the back. From the (very short) video below we also know that the Veloster will be powered by a direct-injection engine (expected to be a 1.6-litre four-cylinder) a married to a dual-clutch transmission. There's also a promise of Bluetooth connectivity and fuel economy is estimated at 40 mpg (5.88 liters/100 km).

Stay tuned for more throughout the week as we report from the floor of the North American International Auto Show.
