Detroit Grand Prix notes:

The Chevrolet Indy Dual in Detroit will be the sixth and seventh Verizon IndyCar Series races conducted at The Raceway at Belle Isle Park. Previous Detroit winners entered include Helio Castroneves (2000-01), Tony Kanaan (2007), Justin Wilson (2008), Scott Dixon (2012), Mike Conway (2013, Race #1) and Simon Pagenaud (2013, Race #2).

The Chevrolet Indy Dual in Detroit are the 16th and 17th Indy car races at The Raceway at Belle Isle and the 19th and 20th Indy car races held in Detroit. A 2.5-mile street circuit in Detroit hosted CART from 1989-1991.

The driver who has gone on to win the championship has won at Detroit three times. Alex Zanardi won on Belle Isle in 1998, Bobby Rahal won at Belle Isle in 1992 and Emerson Fittipaldi won in downtown Detroit in 1989.

Since 1994, seven drivers have won the sixth race of the season and also won the championship. They are: Dario Franchitti (2011, Texas-1; 2010, Indianapolis), Sebastien Bourdais (2004, Toronto), Scott Dixon (2003, Pikes Peak), Cristiano da Matta (2002, Portland), Alex Zanardi (1998, Gateway), Jimmy Vasser (1996, Michigan) and Jacques Villeneuve (1995, Indianapolis). Eight drivers have won the seventh race of the season and also won the championship. They are: Dario Franchitti (2009, Iowa), Scott Dixon (2008, Texas and 2003, Richmond), Sebastien Bourdais (2005, Edmonton), Sam Hornish Jr. (2006, Richmond), Cristiano da Matta (2002, Chicago), Greg Ray (1999, Dover), Kenny Brack (1998, Charlotte) Tony Stewart (1997, Charlotte) and Al Unser Jr. (1994, Portland).

Helio Castroneves has competed in nine previous races at Detroit, most of any driver. Ten drivers entered have led laps at the track (Helio Castroneves 175, Juan Pablo Montoya 117, Mike Conway 78, Scott Dixon 78, Tony Kanaan 30, Ryan Hunter-Reay 20, Simon Pagenaud 18, Justin Wilson 18, Charlie Kimball 3 and Will Power 3.)

Three drivers - Mikhail Aleshin, Carlos Munoz and Jack Hawksworth - will be making their first start at Belle Isle in any series.

The Chevrolet Indy Dual in Detroit will be the fifth and sixth races on a road/street course in 2013. The first four races were won by Will Power (St. Petersburg), Mike Conway (Long Beach), Ryan Hunter-Reay (Barber) and Simon Pagenaud (Grand Prix of Indianapolis).

Here are storylines for the weekend IndyCar Series races in Detroit:
Verizon IndyCar Series prepares for Detroit doubleheader
The Chevrolet Indy Dual in Detroit will mark the first of three doubleheaders on the 2014 Verizon IndyCar Series schedule. Drivers will contest a pair of  70-lap races Saturday and Sunday on the 2.36-mile temporary street circuit, posing a unique challenge for drivers and teams. Will someone sweep the races and be crowned king of the streets in Detroit?
Hunter-Reay looks to continue surge at Detroit
Ryan Hunter-Reay scored the biggest win of his career when he won the 98th Indianapolis 500 on May 25. Hunter-Reay, who finished second in the first of two races on Belle Isle in 2013, took the lead in the championship standings and looks to maintain his momentum. Can he continue his climb towards a second championship with at least one win in Detroit?
Helio returns to site of his first fence climb
Helio Castroneves returns to Belle Isle, hoping to climb the fence at the circuit where he won his first Indy car race in 2000. Castroneves has two victories and two poles at Belle Isle for team owner Roger Penske's team. Can he win again at the Captain's home track?
Watch for Wilson
Justin Wilson is familiar with victory lane at Belle Isle, having won the race in 2008. Wilson returns to the circuit with a team also familiar with victory lane in the Motor City, Dale Coyne Racing. Can Wilson, who won the team's first race in 2009 at Watkins Glen, bring the team back to victory lane at Belle Isle?
Second-generation stars hope to add to family legacy
The latest generation from two of open-wheel racing's most familiar families comes to Belle Isle in hopes of adding to the family legacy. Marco Andretti - the grandson of racing legend Mario Andretti and son of two-time Detroit winner Michael Andretti - comes to Detroit in search of his first win of the season. Another son hoping to return his father's team to Victory Lane is Graham Rahal. The son of inaugural Belle Isle winner Bobby Rahal hopes to turn around a slow start to the season with strong races on Belle Isle.
Detroit native look for win as team owner
Verizon IndyCar Series team owner Roger Penske calls Detroit home and brings a strong chance to win the home race for engine manufacturer Chevrolet. Penske played an active role in bringing back the race to Detroit, and his Team Penske has Will Power, former Belle Isle race winner Helio Castroneves and Juan Pablo Montoya.
Generation Next
James Hinchcliffe, Simon Pagenaud and Charlie Kimball all scored their first win in 2013, finished top 10 in the championship standings and established themselves as the next stars of the sport. Will 2014 be the year a new, young star becomes a champion?
Conway aims for second victory
Mike Conway was a surprise winner at Long Beach, inheriting the lead with three laps remaining and returning Ed Carpenter Racing to the winner's circle. Now, the Englishman looks for another milestone - helping the team win its first entrant championship. Can Conway win again at Belle Isle and help the team stay near the top of the standings?
Follow the Frenchman
Simon Pagenaud claimed his first Indy car win on the streets of Belle Isle in 2013. Now he hopes a strong performance in Detroit can springboard him to the Verizon IndyCar Series title. Can Pagenaud, who won the inaugural Grand Prix of Indianapolis on May 10, maintain his top form on street circuits and gain ground in the title race?
