What do you get the supercar that has everything? McLaren must have been thinking about that question when it came time to give the already rather good 720S a bit of a midlife refresh. The answer is more power, less weight, and a raft of updates here and there that make the new McLaren 750S more useable but also even better on track, if that’s your thing.

Starting from a standard configuration, a 750S weighs 3,062 lbs (1,388 kg), 66 lbs (30 kg) less than the car it’s replacing. But if you select the right combination of options, from single-piece carbon fiber racing seats to titanium wheel bolts, you can trim that down even further—McLaren says to as little as 2,815 lbs (1,277 kg), but that’s a dry weight.

Regardless, the all-carbon fiber construction results in a car that’s both very stiff and lighter than the competition. And the penalty for switching to a retractable hardtop roof is just 108 lbs (50 kg), although it does bring the car’s center of gravity up a smidge.
