The McLaren 765LT is an absolute beast in a straight line, so much so that a stock example recently set a 9.33-second quarter-mile, the fastest time ever for a production car. In order to see how it stacks up against a 720S, Hennessey Performance brought the two together.

In the first race between the pair, they were lined up from a standing start along a non-prepped surface, with both cars using their launch control systems. Out of the gate, the two were very well matched, but as the 765LT put its extra grunt to the ground, it sprinted off into the distance, leaving the 720S for dead. Making the 765LT’s acceleration even more impressive is the fact that it was carrying a passenger.

The second race was from a rolling and confirmed just how insane the 765LT is. During this race, the 720S’s gearbox was in manual mode and locked in first gear while the 765LT was in automatic mode and sitting in third gear. The drivers pinned the throttles of the two cars at 50 mph and despite being in a higher gear, the 765LT immediately sprinted ahead of the 720S and continued to build up an enviable advantage as the speeds increased.

Given how quick the 765LT is straight out of the box, it does make us wonder just what it’ll be capable of once tuning companies like Hennessey Performance start modifying it.
