The Lola B2K/40 was a Le Mans Prototype developed in 2000 by Lola Cars International as a cheaper, smaller, and lighter alternative to the similar Lola B2K/10. Although specifically designed to compete in the SR2 class of the Sports Racing World Cup and Grand American Road Racing Championship, it would later be adapted to the LMP675 and LMP2 classes for the 24 Hours of Le Mans and American Le Mans Series. This design was replaced in 2005 by the Lola B05/40 and would last be used in competition in 2006.
