Introduced as a non-production concept car at the 2010 SEMA show, the "Redline" then only touted a 370HP 5.7L HEMI. Mopar is now teasing us with the idea of a dealer-available 590HP-version (although, the official press release states that Stage III option would be wholly non-smog compliant). We guess we'll have to wait and see...

We’ve chided that were Dodge to redesign the new, considerably-more-retro-designed ’11 Charger’s nose to be a little more reminiscent of the infamous second generation B-Bodies, people might forgive the extra doors. Well, we’re thinking Mopar has a better idea: why not offer three stages of the Redline packages culminating in a 590 horsepower high-output 426 HEMI? Yeah, that should do it.

Unlike the concept seen above, the production Mopar-ized Redline is a little more mellow...at least in the 'looks department.' The usually blacked-out taillight surround is now body color red.

According to Pietro Gorlier, President and CEO of Mopar, Chrysler Group LLC’s service, parts and customer-care brand, “Since the 1960s, the Mopar Brand has built a long history of adding power and performance to the Dodge Charger – and with the Redline, we Moparized the new Charger with modern-day performance and style while giving a nod to our storied past.”

The three tiers of Mopar’s Redline “Stage” packages begines with a full-width chin spoiler, carbon fiber door scoops (hearkening to the ’70 Charger R/T), a two-piece body-colored grille, a carbon fiber rear spoiler, and “Black Envy” 20-inch SRT wheels. Inside is a Mopar aluminum shift bezel and aluminum instrument panel bezel with Redline perimeter accent, with stainless steel Mopar pedal covers.

Stepping up to Stage II adds a little bolt-on performance in the way of a throatier cat-back exhaust system, front-tower cross-brace, and Mopar brake linings to improve stopping performance.

The production Redline doesn't have the super "in-your'face" revised fascia or body-matched grille like the concept, nor the lightweight aluminum and fiberglass SRT8 hood, an option we'd personally prefer.

The real treat comes when you step up to the Dodge Charger Redline Stage III.

This is ‘da big guns, dropping a 590 horsepower all-aluminum 426ci HEMI under the hood that turns a reasonably stout-performing Charger R/T into a menacing machine.

The aluminum engine block drops 100 pounds of weight, and features a forged-steel crankshaft with six-bolt and 4-bolt mains, forged H-beam rods and 11:1 aluminum pistons. All of this spits out 220 more horsepower than the ’12 Dodge Charger R/T and 120 more than the ’12 SRT8.

All of this sounds amazing, right? Yeah, here’s the catch, the 590HP High-Output 426 Gen III HEMI ain’t smog legal. The other problem is that the aggressive roller camshaft (.639 intake and .628 exhaust lift) and aggressively redesigned cylinder heads have been known to play hell with the new engine management system – so we’re figuring Mopar figured this out by replacing the street-friendly ECM with their race/off-road ECM.

Additional goodies include available valvetrain tie bars, cast-aluminum valve covers and billet fuel rails included in the Stage III performance kit. We’re thinking the slightly less insane 540HP all-aluminum 426 HEMI would be a happier medium, as it is both smog legal and equipped with the Multiply Displacement System, bumping up the HEMI’s MPG to 24, but hey, what do we know?
