As SRT continues to work on its HellCat engine package, reportedly to go with both the eight-speed automatic and a hefty six-speed in the 2015 Dodge Challengers, a more complete sketch of the brand’s decal appears to have surfaced.

The new Challenger will be a potent refresh regardless; base models with the V6 will now come with an eight-speed, which should drop 0-60 times to around 6.6-6.8 seconds (based on Charger times with the same powertrain), while increasing highway gas mileage to 31 mpg — assuming the Challenger does not get different performance tuning or gearing than the V6 Charger. The 5.7 Hemi is reportedly due for a minor power upgrade, as is the 6.4 liter SRT engine currently pushing out 470 hp, but since both are also reputed to get the eight-speed, acceleration and economy should improve across the board, regardless.

The supercharged 6.2 engine, which may not be officially unveiled for some time, will be a very limited edition regardless, with pricing expected to roughly match similar setups from GM and Ford — in short, think “over $70,000.” Rumored power ratings are up in the high 600s, with the requisite body stiffening, suspension and brake upgrades, special cooling, and other expensive-to-engineer-and-produce changes needed to handle the power.

So far, rumor has the 6.2 going into Charger and Challenger, but not 300. Whether it makes its way into any other car (or the Grand Cherokee SRT8) is still a matter for conjecture.
