2015 SRT Challenger "Refresh" - Announcement Spring Fest 2014

2015 SRT Challenger "Hellcat"

A teaser announcement was made at Springfest, March 22, 2014, (above) and the actual debut May 20, 2014.





Overview

Name
Engine
[INDENT]

6.2L (376-385 cu/in) Supercharged Hemi - 6.2L (376.79 cu/in) Supercharged Hemi - 600-700 HP / 600-660 lbs-ft TQ (9-12psi)
- iron block (4.09 bore x 3.58 stroke)
- 2380cc twin screw supercharger
- hot-forged pistons and connecting rods
- forged crankshaft
- clutched pulley

So going over some calculated, very rough #'s. Peak HP at 6,000rpms, peak TQ around 3,500-3,800rpms

571hp/541tq - 5-6psi
583hp/552tq - 6psi
594hp/564tq - 6-7psi
606hp/576tq - 7 psi (May 20, 2014 initial #'s; 600+hp/575+tq)
618hp/588tq - 7-8psi
629hp/599tq - 8psi
641hp/611tq - 8-9psi (current durability limit of the 6-speed TREMEC; 600lbs/ft tq)
652hp/623tq - 9psi
664hp/635tq - 9-10psi (possible target #'s; 9.5psi)
675hp/646tq - 10psi
687hp/658tq - 10-11psi
698hp/670tq - 11psi (8HP90 transmission durability limit; 663lbs/ft tq)
710hp/681tq - 11-11.6psi (8HP90 transmission durability limit; 663lbs/ft tq)

Comparable rough outputs of similar engines with boost:
392 (6.4L) with 6psi Magnacharger - 625HP / 580TQ
392 (6.4L) with 7psi Mangacharger - 660HP / 587TQ
6.1L with 8psi Magnacharger - 605HP / 570TQ
6.2L ZL1 with 10-12psi - 630HP / 630TQ - 650HP / 650TQ (injectors and harmonic balancer)

Transmissions[INDENT]6-speed TREMEC TR-6060 manual transmission - torque input of 600 lb-ft / 814nm


8-speed ZF 8HP90 automatic transmission - torque input of 664 lb-ft / 900nm (January 2013 Kokomo Plant Production, replaces the 5-speed NAG1)
The new ZF 8-speed Automatic Transmission has 5 dedicated shift mods. Auto Normal, Auto Sport, Manual Normal, Manual Sport and Extreme Weather. In "M" Manual-mode, the driver can change gears by either Steering Wheel/Column "Paddle Shifters" or use the Trans lever.


The max output of the 6.2L will be limited by it's weakest link; the drivetrain and how much torque it can handle. The weakest links are the transmission, driveshaft and rear axles. The transmission torque input rating is the recommended safe limit of torque input based upon long term durability testing.

The new hellcat engine cannot exceed 600 lbs-ft torque / 814nm (the current TREMEC 6-speed input torque rating) unless the TREMEC gets beefed up.

"The challenger is about to go under the knife, uh it's actually under the knife as we speak. We're doing a lot to it and we're going to come with an answer for that [Z28] and an answer for our friends at Ford. Stay tuned, this space, this time [New York Auto Show] next year you'll see exactly what I'm talking about." ~ Motortrend

Based on the comment made by Ralph Gilles at Spring Fest 2013, and now confirmed through his Motortrend WOT interview, the "refreshed" Challenger will be a MY2015 vehicle that will debut at Springfest 2014 and make an official appearance at the 2014 New York Auto Show (updated to August 2014 based on the new Chrysler 5-year plan).









Based off of the the Chrysler 5-year plan released on January 30, 2013, there are 3 SRT vehicles that will be introduced for CY2014. News: Staggered large-car refreshes in 2014?.

It's in Irvine California. Spring Fest 2013 is going on right now and Ralph Gilles made mention of the quote today.

Hope this excites some of you, not enough to make many sell what they have and buy up to this.

As I have grown older, I've learned that pleasing everyone is
impossible- but pissing everyone off, is a piece of cake.

So I'm guessing by all this that the 2014 Challenger will go unchanged and pretty much stay the same as the 2013's?

MY2015 SRT Challenger "Refresh" - Announcement Spring Fest 2014

Well, I had a chance to speak to Ralph himself today at sf8 in irvine. Spoke to him for about 5 min. He said 2014 hellcat will get refresh (exterior&interior), will have the 8 spd auto, and eaton supercharged I guess by Arrington, and will be crush the completion in his words. Well over 600 HP. He said not to tell anyone. Lol
They have long term plans for the challenger. That was all the time I had since there was a line if people trying to get his autograph and pictures. Thank you Ralph. He also took his time with my kids signing their apparel and took some pictures. Next year the sp will be bigger. They sure have the space for it.
Overall very pleasant day to spend with family and fellow mopar guys.

Just want to make mention that the only "official" photo is the one with the bra cover. The other ones are renderings. I haven't had a chance to revise those images but if you look closer at the spy photos, the new front end looks more like a larger "smiley" face similar to the cuda. Revisions to follow when I get the time.
