WEC drivers Senna, Hartley and Conway get Daytona 24 Hours drives

Senna, an LMP2 class winner in the 2016 WEC with the RGR Sport Ligier squad, and '15 LMP1 champion Hartley will join the Extreme Speed Motorsports Nissan Daytona Prototype international outfit.

Toyota driver Conway, who finished third in this year's WEC, will join reigning IMSA champions Dane Cameron and Eric Curran at the Action Express Racing Cadillac DPi squad.

Daytona doubles as the opening round of the IMSA SportsCar Championship on January 28/29.

Senna has been signed for the four long-distance races that make up the North American Endurance Cup segment of the IMSA series, to drive alongside Johannes van Overbeek and Ed Brown, while Porsche P1 driver Hartley has been confirmed for Daytona only.

Brazilian Pipo Derani, who won Daytona and the Sebring 12 Hours with ESM in 2016, will return to the team to join Scott Sharp and Ryan Dalziel for the NAEC rounds.

Seb Morris joins Conway with the championship-winning Action Express, earning his seat by virtue of winning the Sunoco Whelen Challenge for his successes in the British GT Championship.

Audi driver Filipe Albuquerque returns to Action Express to drive its lead Cadillac DPi-V.R at Daytona alongside former champions Christian Fittipaldi and Joao Barbosa.

Senna, Hartley and Conway are the latest WEC big names to join the Daytona grid, following on Rebellion Racing's signing of P1 drivers Neel Jani, Sebastien Buemi and Stephane Sarrazin.

The second official pre-race test for the 24 Hours begins at Daytona on Tuesday.
