Ryan Hunter-Reay is to stay at Andretti Autosport after the team announced on Sunday that they had agreed a multi-year extension to the driver's existing contact which will take their partnership through to 2017.
"I can't say enough about this partnership from where it's come from day one to where we are now, how much we've grown together as a team. It really does feel like family," said Hunter-Reay, speaking at the Milwaukee Mile ahead of this weekend's ABC Supply Wisconsin 250 where he is the defending race winner.
"I really look forward to winning more in the future," Hunter-Reay added. "I know with this continuity and security we can accomplish so much more."
Hunter-Reay's primary sponsor DHL had also signed on to continue their financial backing of the 2012 IndyCar Series champion, which has been in place for the last four seasons since the start of 2011.
"I'm thrilled to be able to announce today that the relationship between myself, DHL and Andretti Autosport will continue," Hunter-Reay said. "I know that DHL and Andretti Autosport have been instrumental in great achievements. I'm happy to call both organisations family and proud of how we have grown together over the past years.
"Every driver strives to find the stability in their career that allows them to continually grow each year," added Hunter-Reay, who joined the team in 2010 after spells at Rahal Letterman Lanigan Racing, Vision Racing and AJ Foyt Racing.
"Having a home at Andretti Autosport for the last five seasons, working with the same crew and supportive sponsors has no doubt been a key part of our successes. I look forward to all that is yet to come."
Hunter-Reay is still very much in the running to win a second championship in 2014. He currently sits third in the standings behind Penske pair Will Power and Helio Castroneves and with three races to go he's only 63 points adrift of Power - and the final race at Auto Club Speedway alone is worth 100 points to the winner.
"Having a driver as dedicated as Ryan and a partner as supportive as DHL is what every IndyCar team strives to achieve," said Andretti Autosport team owner Michael Andretti. "I'm happy to have shared the last few years with them and look forward to all of the success that will no doubt be in our future together.
"Together DHL and Ryan have won their first series championship and first Indy 500 and we couldn't be happier to have both returning," Andretti added. "This is a big day for big day for us to keep DHL in the family ... It's also a big day for IndyCar racing to have a company like DHL committing to a multi-year deal."
Speaking on behalf of logistics global market leader DHL Express, Chief Customer Officer Christine Nashick said: "The speed, reliability and dedication exemplified by Andretti Autosport, Ryan Hunter-Reay and the DHL IndyCar team is truly an ideal fit for DHL and we are extremely pleased to continue our successful partnership.
"Since we teamed together in 2011, we've been able to successfully connect our global brand with the public and promote DHL as the International Specialists," she added of the new three-year deal with the team. "We look forward to more spectacular years of racing with Andretti Autosport and Ryan."
Michael Andretti added that his team was still working on finding a full-time sponsor for James Hinchcliffe in order to retain the Canadian for another season, and that Carlos Munoz will stay in the line-up in 2015.
He also indicated that the team is working on potentially adding a fifth car to the line-up which is rumoured to be for Simon Pagenaud, who currently races for the Schmidt Peterson Hamilton Motorsport team. However nothing is signed and Andretti said that the plans are not dependant on a specific driver.
