Briton Jay Howard will return to the Indycar Series for its season finale in Las Vegas.
Howard, 30, will join the Rahal-Letterman-Lanigan Racing in what will be his third appearance of the season, after contesting the Indianapolis 500 and the Firestone Twin 275s at Texas earlier this year - with a best finish of 15th.
"It's great to be back with Service Central and Rahal Letterman Lanigan for the IndyCar World Championship at Vegas," Howard said.
"We had a strong run at Indianapolis and a bit of bad luck at Texas so we are looking to finish off the season on a high note in Vegas heading into 2012 with the new car and the expanded schedule."
Howard, who won the 2006 Indy Lights championship, has raced sporadically in the Indycar Series since 2008, when he made his debut for Marty Roth's eponymous team.
After a trying 2010 season with Sarah Fisher Racing, he eased into the Centennial Indy 500 on Pole day, before a solid performance at Texas.
His team boss Bobby Rahal is optimistic about his prospects, despite the fact that Howard has never competed at Vegas before.
"We were impressed again by Jay's pace and the ability that he showed in negotiating traffic at Texas, and we are anticipating a strong effort out of the Service Central car at Las Vegas," said RLL co-owner Rahal.
"Vegas will be a free-for-all on a very fast track, but Jay has never shied away from close racing and we expect to be competitive with both RLL cars in the season finale."
