The supercharger isn't getting any quieter.

Dodge has teased the 2019 Challenger SRT Hellcat again, this time using a cryptic video on YouTube to preview its upcoming muscle car.

The video, titled RED797_62818, shows a Challenger hammering through the desert, with a heavy overlay of supercharger whine to accompany the requisite V8 rumble.

There are a few theories floating around about what the numbers mean, but the most logical is that 62818 is a date (in typically backwards US fashion), more specifically the 28th of June, 2018.

As for the RED797, we'd suggest that's a horsepower figure for the update muscle car, only accessible through the 'red' key included with all Hellcats. Only the red key unlocks the car's full potential, the black key limits the engine's output.

If our speculation is on the money and it does have 797hp (595kW), limited outputs might be a very good idea.

Beyond the numerical game-playing, previous teasers have revealed the new Hellcat will come with a fresh dual-snorkel bonnet reminiscent of classic Mopar muscle cars, while force-feeding the 6.2-litre supercharged V8 even more air.

At the moment, the Hellcat produces 527kW of power and 880Nm of torque, but the SRT Demon has proven there's room for more. It makes 626kW and 1044Nm, put to the road through a drag-strip ready chassis and drag-radial tyres.

Given the base car has been around since 2008 (sure, there have been facelifts) you could be forgiven for wondering if an all-new Challenger is coming. We're wondering the same, but there's no indication as to when an all-new car will be arriving.
