A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 – Chrysler's first, if this goes down – could make its debut this summer.

The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output of the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly less powerful version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.

The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.

      Wish list: Debut this in the 2014 SRT Barracuda to make it sell like hotcakes. Then start offering it in other SRT models.

      Some of the rumors I have read have stated that the Hellcat will be the debut of the all aluminum, next generation, hemi block and heads. The block can also be fitted with MultiAir inside of it (in place of the pushrods), instead of sitting on top with like it does with ohc motors. Hellcat will not debut with multiair though. The next gen heads can be fitted with DI. Hellcat will also not debut with DI. Next gen hemis will have vvt similar to the vipers cam-in-cam setup, instead of cam phasers. Hellcat will have this setup. Hellcat will also have a clutch activated supercharger so MDS will work on it, making it more fuel efficient then GMs supercharged LS. If the hellcat sticks around long enough, with multiair and DI, hellcat can make over 700 hp. Next generation 5.7 & 6.4 should debut approx. one year after hellcat with the 2015 lx car refresh, and spread a cross the Chrysler lineup within that year. DI and multiair will debut a few years later on the next gen ram and grand cherokee. Once again all this info is rumor, but sounds like good business sense if you ask me.

        Much, if not most of this is new to me and makes sense. Unlike many of the reports to the demise of the HEMI, I think it will be a viable engine for the foreseeable future as you indicate. With this new technology and innovation there seems to be a good business case for the developmental cost. As for the four, Fiat will cover that development and improvement process. The pentastar V-6 is the bread and butter engine and will garnish most of Chrysler's investment dollars. As long as there are real American muscle cars. SUVs and Ram pick-up trucks there will be V-8s. The HEMI lives !

      "Allpar contends that a slightly less powerful version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot" The problem is, the Challenger has always been a bit pricey for its performance when compared to the Mustang (and Camaro). I mean the Challenger SRT starts at $40,000 while the Mustang GT and Camaro SS start near $30,000. To keep costs below that of the $55k GT500, it would end up being a lot slower than either the GT500 or ZL1 in a straight line if power is reigned in below 580hp because it's bound to be a lot heavier. As for chassis, it wont be cheap bringing it to GT500 levels of handling, let alone the track devouring ZL1. I say they should not worry about costs and spend the money making a truly competitive model and not a cost cutter half job just to get their foot in the game. Or it could be a few years out and based on the all new and currently completely unknown SRT Barracuda, in which case it would be competing with the new platform Mustang and Camaro and nobody knows much about those either, except for a rumored weight loss and the Stang's been caught with independent rear suspension. But the current challenger platform would need much more than Viper levels of power to beat a GT500 in a drag race (over 700hp with the current SRT8 weight), and it would need a Viper's tires, brakes, and suspension to handle like a ZL1.

        The new Challenger will be lighter and should have little problem covering the Mustang and Camaro in acceleration and cornering skills. I thing the differences are small at this point and the Challenger is a slightly better overall vehicle than the Ford or Chevy in areas most people look for in a daily driver. Just look at the general upward sales of the present Challenger month after month. People like the car and if you drive them side by side, and all three are really good cars for sure, the Challenger more than holds its own and then some. The new generation model will improve that enough to quiet most critics.

          Ive read that the next challenger will be shorter and not as wide. Also to help with the handling, all the suspensions on the next gen lx vehicles will be the same as the new Maserati (quatroportte sp?) setups.

      How bout an engine that is efficient, powerful and people could afford to buy and operate, this BIG numbers game is the 70's all over again and you know how that ended up! They can keep building big number gas guzzlers but refuse to progress.

        Sounds like the muscle car segment is the wrong choice for you.

        Can't disagree with that. Chrysler has chosen brutishness over finesse when it comes to their engines for quite some time now.

        What's funny about these supposedly efficient engines you talk about is how their efficiency suffers under any kind of load... a DOHC engine might sound nice and offer an impressive hp/liter number, but you've got to remember that the faster an engine has to operate to produce X power, the more friction, and more power you have wasted as heat... Not to mention DOHC engines are top-heavy compared to pushrod motors. And with VVT now available to pushrod engines, any advantage the DOHC engine has diminishes even further.

      The hemi has always been known as the elephant engine. BB Chevy is a rat and the SB Chevy is the mouse. And we all no what elephants are afraid of...... Maybe that's why they're calling it the hellcat. We all know what mice are afraid of......

        Wonder why the down vote. I spoke the truth..... Must be the youngsters that don't know the real history of these engines.

      Very cool. I\'ll be excited to see the debut. I just hope they will at least be putting a manual as an option behind these mills.

      This would be just too hot if they debuted it in the facelifted 300 SRT this summer/fall, with the 8-speed. M

      Sounds cool.....but this won't hold a candle to the power output of GM's next supercharged V8. Chrysler makes a good fuel sipper v6 (have it in my 12 wrangler). They should concentrate time on a new fuel efficient 4 instead of these huge things.
