It’s not Indycar, but many current and former Indycar drivers will be driving in the Rolex24 at Daytona this weekend. IMSA has shown steady improvement since Grand Am and the American LeMans Series merged in 2012 and the new series began racing in 2014. The series begins 2018 with new teams, a very large prototype class, and some new full time drivers. Here is a look at the teams with Indycar connections.

Roger Penske starts a full time entry into the series with two Acura prototypes. Former Indy 500 winners Helio Castroneves and Juan Pablo Montoya each drive one of the cars. Castroneves is in the number 7, and Montoya is in car 6. For the Rolex, Graham Rahal will co- drive with Castroneves and Simon Pagenaud will team with Montoya. Ricky Taylor is Castroneves’ full season teammate. Dane Cameron is Montoya’s co-pilot for the full season.

Chip Ganassi continues to field Ford GT cars in the GTLM class. Scott Dixon and Ryan Briscoe drive number 67 this weekend. Sebastien Bourdais will be in the 66.

New Indycar team owner Michael Shank-gosh it feels great to write that phrase- has former Indycar drivers Katherine Legge and A.J. Allmendinger in his 86 machine. Bruno Junqueira drives number 93 for Shank.

Bobby Rahal’s BMW team, cars 24 and 25, race in the GTLM class. Connor DePhillippi is one of his drivers.

Spencer Pigot is back in the 55 Mazda with Team Joest in the Prototype class.

Fernando Alonso makes his endurance debut in car 23 for United Autosport. The car is a Ligier Prototype, one of ten LMP2 cars.

Ryan Hunter-Reay is driving car 10 for Wayne Taylor Racing, the defending race champion team.

Two drivers from Indy Lights of note- Pato O’Ward, who returns for a full Indy Lights season this year, will drive the Performance Tech number 38; Felix Rosenqvist, who had a brief run in Lights and is the current pints leader in Formula E, co-drives the Jackie Chan entry number 37.

Fifty cars will start the race Saturday. There are 20 prototypes, 9 GT Le Mans cars, and 21 GT Daytona machines. Gone is the Prototype Challenge class.

I plan to watch the Indycar test at Sebring on Wednesday before going to Daytona. 15 cars are scheduled to test, including newcomers Carlin and Shank. It should be a busy day.

The Cadillacs of Wayne Taylor Racing and Action Express will be strong again. I’m interested to see how strong the Penske Acuras are in their first race. They should be contenders later in the year. Ganassi Ford GTs will likely dominate the GTLM class. The GT Daytona class is usually wide open, but I’ll go with the Porsche 911 team for the win.

I hope to post about it Wednesday night and provide update from Daytona this weekend.
