Watch a previous-gen McLaren 675LT take on a new McLaren 720S in a ½-mile drag race.
We’re still at WannaGoFast in Florida where DragTimes has taken an entire menagerie of supercars to do battle against a similar number of high-octane vehicles in ½-mile drag races. However, these drag races are on an unprepared airstrip and not a prepared drag strip, meaning that the performance of these cars will much better reflect real-world performance.
Not that we needed convincing of a McLaren’s performance.
This time we have a battle of old versus new. The McLaren 675LT was the best of the best for the older generation of McLaren supercars, using the same 3.8-L twin-turbo V8 engine that eventually found its way into the current 570S. In the 675LT, however, it’s been tuned to the nines to produce 666 hp and 516 lb-ft of torque, which is a big boost over the current 570S.
Zero to sixty is done in 2.8 seconds on its way to a top speed of 205 mph. As an LT model, the 675LT comes in just shy of 3,000 lbs, giving it the slight weight advantage over its bigger, newer brother.
The 720S comes with a larger 4.0-L twin-turbo V8 with 710 hp and 568 lb-ft torque. Zero to sixty is done in 2.7 seconds with a top speed of 212 mph. It does weigh a little more at 3,180 lbs, but the 720S is still the clear favorite to win in any contest between the two.
Both cars are bone stock with fresh tires. The only question is just how badly the 720S will beat it’s lighter sibling.
Turns out it was by a lot.
To be fair to the 675LT driver, it seems his launch control was acting up and preventing the car from taking off on command. In the first race, the 675LT didn’t even bother starting until the 720S was already halfway down the track, while in the second race it still seemed to hesitate before pulling off the line. In both races, the 720S kept expanding the gap with no hope of the 675LT ever closing it.
The trap speed at least cares not a whit for time as it only calculates speed at the finish line. The 720S finished at 170.1 mph, while the 675LT finished at 162.8 mph. Not a huge difference, but it’s a clear win for the 720S.
