After unveiling two new Utlimate Series models – the Senna and the Speedtail – earlier this year, McLaren has now introduced a more 'subtle' supercar to add to their Super Series lineup – the 720S Spider. The new drop top version allows customers to experience the 720S's full performance but with all the open sky and fresh air above them.
Surprisingly, the performance figures of the drop top 720S are close to that of the coupe's. Usually, open top supercars experience reduced performance over their coupe counterparts because of the roof being chopped off and reinforcements being added. That doesn't seem to be the case with the 720 Spider though as both use the same 4.0-liter biturbo V8 engine rated at 720 PS.
In fact, both the 720S Spider and Coupe share an identical 0 to 100km/h time of 2.9 seconds. It only loses to its fixed roof counterpart in at the 0 to 200 km/h sprint, needing 7.9 seconds compared to 7.8 seconds. Let's be honest though, that's something barely noticeable. Top speed is still rated 341 km/h with the roof up. Fold the roof down, and top speed is also reduced to 325 km/h.
McLaren was able to achieve this because of the new electrically actuated one-piece carbon fiber roof panel. The retractable hardtop can be raised or lowered in just 11 seconds, 6 seconds fasters than its predecessor the 650S Spider. It can also be moved at a higher top speed, 50 km/h compared to the previous 30km/h.
All-in-all, the weight penalty of the 720S Spider adds up to only 49 kg, giving it a dry weight of 1,332 kg. McLaren even claims it to weigh "88 kg less than the dry weight of its closest competitor." While the Woking-based company did not name any car specifically, the statement was more or less aimed at the Ferrari 488 Spider.
