While Felipe Nasr, Eric Curran, and Mike Conway already know what their plans are for January, there is still one name yet to be added to the driver lineup in the No. 31 Action Express Racing Cadillac DPi-V.R for January’s Rolex 24 At Daytona.

That name will be decided this weekend in the final event of the 2018 Sunoco Whelen Challenge, which provides the champion with the opportunity to race the No. 31 Whelen Engineering-backed Cadillac.

Stuart Moseley has one final chance to deny Stuart Middleton the title and Rolex 24 At Daytona prize drive this weekend when he contests the Radical European Masters season finale at Barcelona.

Moseley is the only driver with a mathematical chance of beating Middleton, whose British GT4 title-winning campaign came to a close at Donington Park in late September.

He can score points for fastest laps, pole, and overall result in each of the three Radical races on the weekend. If he can win all three, he could just emerge with a shot at the Rolex 24.

The Sunoco Whelen shoot out is now in its ninth season, with the champion driving the No. 31 Whelen entry every year since 2014.

Whomever emerges to get the nod to drive the No. 31 Cadillac will be added to the list of previous Sunoco Whelen Challenge winners Seb Morris (2017), Jonny Adam (2016), Phil Keen (2015), and Bradley Smith (2014) who have raced the Whelen entry in the Daytona classic.

One racer who earned the Sunoco Whelen championship was Nasr, who scored a Rolex 24 podium in his 2012 debut appearance in the event. Nasr has joined the team as a full-season co-driver with Curran in the No. 31 Whelen Engineering Cadillac DPi-V.R in 2018.

“We’ve seen some great talent come through the Sunoco Whelen championship, and with the title on the line this weekend we will be paying close attention to the results to see who will be joining us in Daytona next year,” said Action Express Racing team manager Gary Nelson.

“It is a great opportunity for these drivers to compete in the Rolex 24 and I think that’s why we’ve seen these championships come down to the wire for the last few years!”
