The 2014 Chevrolet SS is the primary Chevrolet to take SS as a model name rather than a trim designation, and the primary rear-drive Chevy sedan since the 1996 Impala SS.
No, the 2014 SS is just not exclusively a Chevy at its core, or at the very least not a Chevy first and foremost. The billion or so spent growing this automobile will likely be recouped largely by its company sibling, the Holden VF Commodore. Its speedy predecessor, the VE Commodore, was Australia’s greatest-promoting automobile for 15 consecutive years.
The SS will ultimately characterize a tiny sliver of GM’s North American sales, providing the third leg underneath Chevy’s performance stool with the Corvette and Camaro. SS chief engineer Dave Leone concedes that the SS “is not a high-quantity automobile, when it comes to its priorities and capability,” however he insists that it was created as a Chevy from the beginning, with key parts not supplied in any Holden, starting with the engine.
The SS’s centerpiece and first draw is Chevy’s Gen IV LS3 V8 — better often known as the bottom engine within the C6 Corvette. Horsepower peaks at 415 and torque at 415 lb-ft, down 15 hp and 9 lb-ft from the 2013 Vette, thanks largely to the intake and exhaust paths. Its transmission is GM’s 6L80 six-pace automatic — additionally developed for the C6 and installed within the SS with the same with TAPshift sport electronics and an identical ratios. A restricted-slip rear-finish comes normal, with a 3.27 closing drive ratio.
The suspension is not terribly fancy — just essentially sound: MacPherson struts in front with twin lower links; an independent multilink association rear, with coil-over shocks and three lateral ball joints per side. Compliance is managed with progressive rate shocks and springs quite than GM’s adaptive Magnetic Trip Control (although the SS electrical architecture allows quick adaptation of MRC, and we wouldn’t be shocked if we see it sooner or later). A range of aluminum suspension bits and physique panels assist maintain the SS’s center of gravity low and weight balanced 52 % entrance, 48 percent rear.
The steering rack is mounted ahead of the front wheel facilities and boosted by a rack-mounted electrical motor, related with a belt. Electrical assist allows Chevy’s first self-parking program. More significantly, the belt provides an insulating ingredient that enables extra mechanical suggestions from the rack, outlined by back-pushed resistance on the steering wheel.
Its brakes are equipped by Brembo, with 14-inch two-piece rotors and four-piston aluminum calipers in front. The wheels are cast and staggered, and the SS will come with summer season-solely Bridgestones–245/40ZR19 front, 275/35ZR19 rear. Those make it the first Chevy sedan provided solely with extremely-high-efficiency tires and the NVH challenges they present.
It’s coincidence that the SS’s length and wheelbase match the new Cadillac CTS. The CTS starts with GM’s Alpha platform, shared with the compact Cadillac ATS and built in Lansing, Mich. The SS starts with Zeta, which in its previous iteration offered the inspiration for the Camaro and Pontiac G8, and it’s in-built Australia. Evolution from the final Zeta includes extra excessive-power steels, a 66-pound weight reduction, new suspension structure and new electrical system.
The SS is big, with the same inside volume and 35 p.c extra trunk space than a Mercedes-Benz S-Class, based on the EPA, on a considerably shorter wheelbase. No one at Chevy is evaluating the two, although the SS appears to be like like good value at half the value of an S550. It is as fast off the road and sooner (161 mph prime velocity) — and we might guess faster ‘spherical a racetrack, with extra grip.
Straight up marketplace competition is limited. It in all probability doesn’t included the V6-powered Ford Taurus SHO, which is smaller inside and heavier than the SS. The SS’s solely direct competitor might be the Dodge Charger SRT8.
The Charger’s bigger, iron-block Hemi has the ability advantage, with 55 hp and 55 lb-ft greater than the SS LS3. The Dodge, however, weighs practically four hundred pounds more; with that, the power-to-weight ratio evens out dramatically. Brake specs are basically identical. The Charger presents adaptive suspension. The SS has an extra gear in its automatic, a bit extra tire, more standard gear and $2,000 value edge.
SS, for Super Sport, was first utilized to a $55 possibility package on the 1961 Impala, including chassis reinforcement and stiffer springs. Over the years the badge has held on Chevelle, Nova, El Camino, Monte Carlo, Silverado, Cobalt, HHR, etc. You may at the moment purchase a Camaro SS. It has been a label that means efficiency first, and that was the pondering with the mannequin named SS. There is no much less-highly effective engine choice or extra luxurious LT trim. Just an SS.
At $44,470 including destination, the SS comes standard with navigation, leather/Alcantara inside, head-up show and a security suite that counts eight airbags, forward collision alert, lane departure warning, ad infinitum. Options are limited to a sunroof ($900) and full-measurement spare ($500). You can in all probability find one at larger Chevy stores now.
