Narain Karthikeyan has confirmed reports that HRT will not race an entirely new car in 2011.

The struggling Spanish team with its car designer Dallara in 2010, and a new partnership for this year with Toyota Motorsport GmbH also foundered.

It recently emerged that HRT would begin pre-season testing at Valencia next month with the 2010 car, but a report by the Indian news agency PTI claimed that an "upgraded version" of the F110 will in fact contest the 2011 season.

"They (HRT) will participate with an upgraded version of their 2010 chassis, mated to the Cosworth engine, and a gearbox sourced from the Williams team," 2011 driver Karthikeyan is quoted on Tuesday by sport360.com.
