Vettel impressed after test-driving New Jersey track

Formula 1 world champion Sebastian Vettel gives the thumbs-up to the layout of the proposed track in New Jersey - for a race to be known as the Grand Prix of America - after test-driving it in a road car.

Red Bull driver Vettel reveals he is "surprised by the elevation change" in the 2.3-mile circuit, set against the backdrop of the Manhattan skyline, and believes there "should be some really nice corners" when it is finished in 2013.

The New Jersey race could be the second new race in the United States after the US Grand Prix which is due to be held on 18 November this year on a purpose-built track in Austin, Texas.
