At the Goodwood Festival of Speed, I thought I was ready for anything, until I saw the Lanzante-built McLaren P1 HDK LM-25.

McLaren P1 drag races the $350K Ferrari 296 GTB over the quarter-mile to answer the $1.29 million question: is it worth it?

Taken by itself, the turbocharged V-8 found in the McLaren P1 is good for a whopping 727 horsepower and 531 lb-ft of torque, with the engine capable of spinning all the way up to an 8,500-rpm redline.
