Meanwhile, a Daimler-era Chrysler rounded up all their horsepower-junkie engineers, locked them in a room, and slapped an SRT badge on the door. Like a grenade going off in a small closet, it didn’t take long for these modern-day Ramchargers to scatter buckshot through the performance ranks at GM and Ford.
Dimensionally, the new Camaro is slightly trimmer in all exterior dimensions and notably in a nearly 2-inch reduction in wheelbase but the overall effect is more dramatic, particularly with almost fastback profile. It simply looks lean and taught.
We were late to get the 2015 Scat Pack in the annual rounds of Chrysler’s press fleet rotation. Frankly, with all the focus on the SRT Hellcats, cars just weren’t in the system for us to drive. As a result, interested Scat Pack customers will most likely be looking at the 2016 model.
The Dodge boys tried nibbling at the edges of the performance/value proposition with cars like the GLS, GLHS, Viper, and even V-8 Dakota, but the engineers in Auburn Hills never had all the right goodies in the parts bin to snatch victory from their cross-town rivals in Detroit and Dearborn. They kept trying though, and once the LX platform came on line in 2005 with the 5.7L Hemi-powered Chrysler 300C and Dodge Magnum, a nascent ember of hope grew into a large movement that has ignited Mopar faithful and conquest buyers alike.
Our technique in the 2015 GT is the same as in previous Mustangs. We find an upright driving position to get good leverage on the shifter, and keep our hand on the shifter during launch so we’re ready to go.
We ended up with a few 13.0 runs and a best of 12.94 at 112.58. It took a little longer than we anticipated to find the sweet spot for launching. As always, more time would have equaled better e.t.’s. In the end, our best run came from revving the 5.0 to approximately 3,200 rpm, and by releasing the clutch smoothly and rolling the throttle to the floor, rather than smashing it open. Drag radials and 3.73s would have gotten us in the 12.50s or 12.60s, based on the mph.
The all-new 3.6L V-6 is optional in the LT and is rated at 335 horsepower and 284 lb-ft of torque. It features direct injection, variable valve timing and, for the first time, Active Fuel Management (cylinder deactivation), which disables two cylinders. The 2.0L turbo and 3.6L engines are offered with a standard six-speed manual transmission or GM’s all-new 8L45 paddle-shift eight-speed automatic transmission, which is based on the eight-speed design introduced in the Corvette and fullsize trucks.
Some will tell you burnouts are unnecessary when driving on stock tires, we disagree. Why? Because tires pick up pebbles and debris, especially in the pits at a race track. If you try to launch with all this crud on your tires, you’ll probably spin. It’s like running on marbles. You can imagine how that would end. Doing a burnout, even a short one, cleans the tires and offers the best rubber-to-rubber contact.
So how do you make the Shelby Raptor even better, how about slapping on King off-road racing shocks, all-new 35×12.5R18 BFGoodrich All-Terrain T/A KO2 tires wrapped around a set of custom 18-inch wheels and, oh yeah—stuffing a supercharger under the hood to give it 700hp.
The 2015 Shelby GT Mustang starts off with the very same 5.0L Coyote V8 from the Mustang GT but the similarities end there as the Shelby GT features a Ford Performance Racing Parts 2.3L TVS supercharger that bumps the power output all the way up to 650hp. You’ll also notice the unique Shelby aluminum caps on the overflow tanks that give the Shelby GT a little more sophistication under the hood. A Shelby cold air intake ensures the supercharged Coyote gets an adequate supply of air to let all 650 horses loose at a moment’s notice while a set of 3.73 gears allow the Shelby GT to get moving in a hurry.
The 2015 is comfortable and nimble on the street. It has good power and a great sound too. We were anxious to get on track, do a real burnout, and launch on a prepped surface. What we found is that the 2015 Mustang is tricky to launch compared to the out-going S197 Mustang. Why? In layman’s terms, the live axle in the S197, which is considered somewhat crude, provides great feedback for drag racing. The three-link suspension does a fantastic job of planting the tires and transferring the torque loads to the body to create pitch rotation (nose lift) to transfer weight from front to back. The heavy axle assembly also gives lots of feedback to the driver and really communicates what the tires are doing.
The LT1 engine is available with a standard Tremec TR6060 six-speed manual transmission that borrows the Active Rev Match technology from the Corvette’s seven-speed manual. It “blips” the throttle automatically on downshifts. It’s very effective, but a little disconcerting the first time you use it. The Hydra-Matic 8L90 paddle-shift eight-speed automatic is optional.
Throughout the ’80s, ’90s, and the first decade of the new millennia, Dodge was—to put it bluntly—bad at math. Ford and Chevy (and Pontiac in earlier years) adeptly applied the age-old hot rodder’s calculus of horsepower divided by weight divided by MSRP. This performance quotient resulted in a hot horsepower battle that saw almost yearly changes in the top-dog spot, and an upward spiral in the performance index as a whole. Except in Chrysler-built products.
