Accompanying this video was a press release that detailed a few of the car's specs. The most import being the fact that the car can reach 124 mph in just 7.8 seconds and then brake to a standstill in 4.6 seconds and 117 meters-- that's six meters less than the 650S it's replacing.

“As well as delivering the outstanding driver involvement and enjoyment for which the brand is renowned, McLaren’s new supercar will also excel in everyday driving,” explained Goodwin. “The extreme performance and dynamic prowess of the second-generation Super Series, honed by testing at the limits and beyond, provides the perfect foundation for it to be the most complete supercar across the full range of use.”
To handle the exceptional braking abilities of the new McLaren 720S are lighter and stiffer brake calipers, as well as carbon ceramic discs as standard. There are also new shoes attached to the car, which are bespoke Pirelli P Zero Corsa tires that McLaren worked with the tire manufacturer to create.
