Former BMW and Renault F1 driver will contest the entire FIA World Endurance Championship with the ByKolles LMP1 team.
Kubica enjoyed a very satisfactory test with the LMP1 outfit in Bahrain back in November, and believed at the time that a full WEC schedule was a possibility.
The Pole attempted to branch out into the WRC after recovering from a heavy arm injury sustained in a rally in 2011 which put an end to his F1 career.
He now has set his sights on road racing once again, contesting last month's Dubai 24 Hour race with a Porsche 911 GT3-R.
"After my time in rally I’ve been looking for something as close to Formula 1 as possible," said Kubica.
"This is exactly what I’ve found in LMP1. At the end of last year’s WEC-Season, I was able to do my first laps behind the wheel of the CLM P1/01.
"I felt comfortable in the car very quickly and was able to increase my pace accordingly. With even more experience I’m sure I will be able to extract more performance.
"I’m already very much looking forward to the Prologue in Monza and the season start in Silverstone."
