For us automotive journalists, these data tell a lot. If the times are so close, and the difference are so narrow (in some cases fully negligible) that means one thing:
The car which has the smaller brakes, smaller tires, smaller displacement, lower power & torque figures ultimately wins the efficiency battle, because it is utilizing its resources way better. Or say, the car that has big engine/tires/brakes etc., and does a very comparable lap time (all variables included), is a weaker one, because it should produce significantly higher performance numbers according to its resources.
Honda has developed a very smart chart, the Milky Way chart, that helps to position the performance characteristics of any given high performance vehicle. The Honda NSX was used as a benchmark for the development of more than a few legendary sports cars - including the all-conquering McLaren F1 GTR, and more lately the Ford GT (transmission, drivetrain).
