So how does the 2015 Shelby GT handle? Lucky for us, we got the opportunity to take the car for a spin and we got to experience just what this 650hp beast is all about. While it feels incredibly fast, you aren’t constantly worried about giving it too much throttle and spinning out. The traction control seems to keep it tracking straight when you crack open the throttle and the sway bars help it hug the curves, even under power.
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.
We noticed a slight amount of wheelhop when doing a burnout in the 2015 Mustang. This seems to be common, but it can be reduced with stiffer rear bushing. In the name of proper reporting, we tried doing burnouts both ways and found both methods to be effective.
But more than the history and visual cues, the Scat Pack package is a nod to all the engineering and performance upgrades that must necessarily accompany a powerplant of this magnitude. Improvements over the 5.7L Hemi R/T Challenger include larger four-piston Brembo brakes, wider and taller 20-inch rubber, a larger-diameter 2.75-inch dual stainless-steel exhaust system, Performance Pages, aerodynamically enhanced spoilers, an uprated 3.09:1 limited-slip rear, higher-output 220-amp alternator, and High-Performance suspension. And except for Performance Pages, it’s all needed to safely meet the needs of the Scat Pack’s 177 mph top speed.
Shelby American is a name that is famous for power and performance in the automotive world thanks to its long historic racing pedigree in the early 1960s to present. Many Mustangs have rolled out of the Shelby’s doors to conquer both the street and track and for 2015, they are pulling out the stops with their all-new S550 Shelby GT Mustang. The S550 Mustang also features a fully independent rear suspension on its entire lineup, which has all corner carving enthusiasts excited.
Importantly, about 70 percent of the architectural components are unique to Camaro; and compared to the Gen 5 architecture, structural rigidity has increased 28 percent. The new structure also represents the bulk of the Camaro’s weight loss, in everything from the switch from a steel to aluminum instrument panel frame, to lighter suspension components. They even designed honeycomb-style lightening “holes” in a number of components to save fractions of pounds here and there.
Certain models of the 2015 Mustang have Launch Control. You can use this driver aid or do everything yourself. Either method requires a cool head on the line and smooth release of the clutch. Once you’re staged, your adrenaline will be pumping and you’ll be itching to unleash all that power. Launching on street tires is tricky, so your full concentration will be required.
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.
That’s all great, but we’re more excited about the Camaro’s new, multi-link MacPherson strut front suspension, which leverages a double-pivot design that makes those Cadillacs so agile. At the rear, a new five-link independent suspension yields outstanding wheel control and reduces “squat” during acceleration. All-new Drive Mode Selector is offered and tailors up to eight driving attributes for four modes: Snow/Ice, Tour, Sport, and on SS models Track.
We recommend doing only enough of a burnout to clean the tires, as street tires don’t really react like slicks or drag radials. Don’t sit there and smoke ’em too long, or you will draw the oils from within the tire to the surface and that will actually make them slick, not sticky.
A set of Rouge Racing upper and lower control arms offer a heavy duty suspension package that can hold up to the stresses of high-speed off-road jaunts while a set of King 2.5-inch coilover remote reservoir shocks soak up the hard hits and smooth out the bumps. Out back, a set of King 2.5-inch bypass shocks keep the truck floating over the whooped out roads.
Luckily for us, the folks at Shelby American just happened to stop by our L.A. offices to give us an exclusive first look at the all-new Shelby GT. Naturally we brought along our camera and snapped away at 2015 Shelby GT Mustang from just about every angle. It’s definitely a head turner that also packs plenty of power and performance to go along with it.
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.
