They’re two of the quickest cars on the planet, and yet they could hardly be more different.
Sure, both the Dodge Challenger SRT Demon and the McLaren 720S have two doors, four wheels, and a fixed roof. Futhermore, both are powered by forced-induction V8s: a supercharged unit in the Challenger, and a twin-turbo mill in the McLaren. But where the Dodge is a big, semi-attainable, blue-collar pony car designed to dominate on the dragstrip, the McLaren 720S is a lightweight, blue-blooded supercar for the one percent.
There’s about 1,400 pounds of weight, and something like $200k of American greenbacks, separating the two lightning-quick coupes.
It’s a safe bet – given McLaren’s racing roots, the 720S’ supercar aspirations, and the car’s lighter curb weight – that the McLaren would handily outrun the Dodge Challenger SRT Demon on a road course, but which is the quicker car in a show of straight-line acceleration, on everyday street pavement? The Challenger is more potent, producing 808 horsepower on pump gas (840 on racing fuel), and SRT has published some staggering numbers for the car: 0-to-60 in 2.3 seconds, on to a 9.65-second quarter-mile at 140 mph.
But of course, those numbers are based on rather ideal conditions, with the car rolling on a grippy set of drag radials over a well-cared-for dragstrip, with a tank full of racing fuel. The folks at DragTimes were more interested in the street performance of each car, so recently, they rounded up a Dodge Challenger SRT Demon and a McLaren 720S, pitting them against each other in a pair of rolling races on the freeway.
