The  Lola B01/60 was the first chassis designed exclusively to the LMP 675 rules.  Originally commissioned by MG as the MG-Lola EX257,  the chassis benefited from Lola's experience with their B2K/40 and B2K/10 chassis.  This was exemplified by elements from both cars showing up in the B01/60.  The Lola is a very contemporary carbon tubbed, single hooped, light-weight LMP chassis.  Under 2003 ACO LMP 675 rules, the Lola was in theory capable of taking the race to the bigger LMP 900 cars.   In a rough comparison of published weights (2002 ACO scrutineering weight) and horsepower between the MG-Lola (450 hp, 1509 lbs.) and Audi R8 (a very conservative 550 hp, 2000 lbs.), the Lola actually had a power to weight advantage of 3.35 lbs./hp, compared to the Audi's 3.63 lbs./hp.  Add to that an advantage in fuel consumption and tire wear (which equates to less time in the pits), when all is said and done, it shouldn't have been a surprise when the Dyson Racing entered Lola-MG won overall at the Sears Point round of the American Le Mans Series.
