2015 CHEVROLET SS BOLSTERS PERFORMANCE WITH
MAGNETIC RIDE CONTROL AND SIX-SPEED MANUAL TRANSMISSION
The Chevrolet SS returns for 2015 with more performance-oriented features that enhance its dynamic driving experience, including Magnetic Ride Control, a six-speed manual transmission and Brembo rear brakes.
“The SS reinforces Chevrolet’s position as America’s performance car brand and affirms what we’ve believed all along – enthusiasts want the driving experience that only a rear-drive sedan can provide,” said Brian Sweeney, U.S. vice president, Chevrolet. “And by the way: BMW is the top non-GM-brand trade-in from SS customers.”
Magnetic Ride Control – the world’s fastest-reacting damping system – provides more precise body motion control that correlates with a more responsive, more refined ride. It is standard on the SS and features driver-selectable Tour, Sport and Performance modes.
The new six-speed manual is available alongside the paddle-shift six-speed automatic, and the new Brembo rear brakes complement the Brembo front brakes that have been part of the SS’s equipment roster since its debut.
“The enhancements for 2015 make an already exciting car even more capable,” said Sweeney.
Indeed, the SS’s new chassis features and transmission complement its race-tested, global rear-wheel drive architecture. Power comes from the LS3 V-8, delivering an SAE-certified 415 horsepower (310 kW) and 415 lb.-ft. of torque (563 Nm).
With the automatic transmission and its performance-oriented 3.27 final-drive ratio, the Chevrolet SS accelerates from 0 to 60 mph in about five seconds, making it one of the quickest sedans on the market. Models equipped with the new manual transmission feature a more aggressive 3.70 axle ratio for even stronger acceleration.
And to ensure it turns and stops as well as it accelerates, the Chevrolet SS also features a sport-tuned chassis with features include:
- MacPherson strut front and multi-link independent rear suspension geometry
- Electric power steering system, optimized for sport driving
- Standard Brembo brakes with four-piston calipers and ventilated, 14-inch (355 mm) front rotors and 14.2-inch (360 mm) rear rotors
- Forged aluminum wheels, wrapped in ultra-high-performance Bridgestone tires: 19 x 8.5-inch wheels with 245/40ZR19 tires in front; 19 x 9-inch wheels with 275/35ZR19 tires at the rear.
Handling is also optimized with a nearly 50/50 weight distribution and a low center of gravity – attributes made possible in part by the aluminum hood and rear deck lid that are 30 percent lighter than traditional steel panels.
Additionally, the 2015 Chevrolet SS is better connected with new OnStar 4G LTE and a built-in Wi-Fi hotspot (includes 3GB/three-month data trial). Five new colors are also added to the exterior palette: Perfect Blue, Some Like it Hot Red, Alchemy Purple, Jungle Green and Regal Peacock Green.
The SS’s good looks blend performance cues and premium details. Staggered front and rear wheels, which are pushed out to the corners, enhance the sporting, muscular stance of the SS. Up front, the aluminum hood features a subtle “power bulge” hinting at the capability of the engine underneath.
At the rear, the tapered, tear-drop shape contributes to improved aerodynamic performance. Premium cues include jewel-like chrome accents, standard high-intensity discharge headlamps and light-emitting diode daytime running lights.
Along the vehicle’s sides, a character line extends from the hood to the trunk lid, helping create a classic wedge shape by further accentuating the planted appearance and muscular sheet metal. The vehicle tapers at the rear, with the C-pillar flowing into the deck lid – a design cue shared with other Chevrolet sedans.
Bright dual-exhaust tips put an exclamation mark on the rear design, while delivering the throaty note performance enthusiasts expect from their vehicle.
Premium, spacious interior
The spacious interior of the SS will comfortably accommodate five adults, with 42.3 inches of front legroom (1,074 mm) and 39.7 inches (1,008 mm) of rear legroom. Leather seating surfaces are standard, as are eight-way power adjustable front bucket seats with additional side bolstering that hug the driver and front passenger in tight-handling situations.
The SS emblem is prominently stitched onto the soft-touch instrument panel which features two types of chrome finishes – a satin gloss and bright chrome.
An integrated center stack includes infotainment, climate and other vehicle controls, while the center console of the SS houses dual cup holders that can accommodate a wide range of container sizes. The cup holders are not separated, so the space can also be used for small item storage. Fold-out rear cup holders are also located at the base of the center rear seating position. In addition, all four doors contain cup holders. An electric park brake frees up additional space in the center console.
Two auxiliary power outlets allow concurrent charging of items such as mobile phones, tablets and portable satellite navigation devices. One is located inside the covered central storage console; the other outlet is conveniently accessible in the forward compartment at the base of the instrument panel.
A USB outlet is located on the vertical face of the covered storage console. The Chevrolet SS also offers a long list of standard technologies including:
- Color, in-dashboard touch screen that supports Chevrolet MyLink and the standard GPS-based navigation system
- Audio system with navigation – including SiriusXM radio (with 12-month trial)
- Bose® 220-watt, nine-speaker premium sound system
- Color head-up display and color driver information center
- Dual-zone automatic climate control
- Alloy pedal covers
- Heated and ventilated front seats
- Leather-wrapped shift knob and steering wheel
- Keyless access and push-button start
- Remote start (with automatic transmission).
The SS interior is offered exclusively in black, and a power sunroof is available.
MyLink and OnStar 4G LTE
The Chevrolet SS’s MyLink system gives customers the best of both worlds when it comes to infotainment. It provides easy, intuitive operation of basic functions, yet it is also highly customizable and capable of linking multiple devices such as smartphones, SD cards and MP3 players, giving users more ways of staying connected.
Enhanced connectivity and convenience includes a Text Message Alert feature for smartphone users with Bluetooth profile (M.A.P.), which reads incoming texts through the vehicle’s speakers, and Siri Eyes Free for iPhone iOS 6 and iOS 7 users to enhance connectivity and convenience. Each enables voice-controlled connectivity, to help keep phones safely stored and hands on the wheel.
Complementing MyLink to enhance the SS’s connectivity is new OnStar with 4G LTE and standard built-in Wi-Fi hotspot. It provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a 3GB/three-month data trial.
4G LTE is the most current and fastest mobile data network – 10 times faster than 3G and 100 times faster than a 2G network. And with OnStar, it also offers stronger, broader coverage than smartphones on the same network and it’s easy to use: If the vehicle is on, the connection is on.
At the time of purchase, six months OnStar Directions and Connections includes all of OnStar’s advisor-based safety and security features, including Automatic Crash Response and Stolen Vehicle Assistance, as well as turn-by-turn navigation.
Five years of OnStar Basic Plan includes RemoteLink Key Fob Services, allowing owners to remotely start and lock/unlock a car (if properly equipped), and activate the horn and lights from anywhere with a data connection. It also includes OnStar Vehicle Diagnostics, which runs monthly checks of a vehicle’s engine, transmission, anti-lock brakes and more, and Dealer Maintenance Notification, which sends a diagnostic report directly to a preferred dealer to simplify service scheduling.
Powertrain and suspension
The 6.2L LS3 small-block V-8 is the power behind the SS’s driving experience. It is SAE-certified at 415 horsepower (310 kW) and 415 lb.-ft. of torque (563 Nm). The engine’s torque is channeled to the limited-slip rear axle via a TREMEC TR6060 six-speed manual or Hydra-Matic 6L80 six-speed automatic transmission with paddle-shift control.
A 3.27 axle ratio is standard with the automatic transmission and a 3.70 gear is matched with the manual transmission. An engine oil cooler is standard and a transmission cooler is included on automatic-equipped models.
The SS’s sport-tuned suspension complements the powertrain with handling prowess and driving refinement. The front suspension is a MacPherson-strut-based multi-link system with a direct-acting stabilizer bar. It features a forward-mounted steering rack and dual lower links with individual ball joints at the outer ends.
At the rear is a multi-link independent suspension with high lateral stiffness for great handling, thanks to three lateral ball joints per side. A rubber-mounted rear suspension frame isolates the body from road imperfections and drivetrain vibrations, while lightweight aluminum suspension components front and rear, including the front steering knuckle and tension arms, contribute to tremendous ride and handling characteristics.
Damping for the sophisticated front and rear suspension designs is all-new for 2015 with third-generation Magnetic Ride Control. Its sensors “read” the road every millisecond, triggering damping changes in as little as five milliseconds in electronically controlled shock absorbers that replace the SS’s conventional mechanical-valve shocks and struts. They’re filled with a magneto-rheological fluid containing minute iron particles and under the presence of a magnetic charge, the iron particles align to provide damping resistance.
Changes in the magnetic charge alter the damping rate of the shocks, with changes occurring almost instantly, delivering more precise body motion control. That translates into greater feelings of precision, responsiveness and refinement, particularly on rougher roads or when cornering. The selectable Tour, Sport and Performance modes allow the driver to determine the amount of damping desired.
Brakes and steering system
Track-capable Brembo four-wheel disc brakes are standard, with ventilated 14-inch (355 mm) front rotors and 14.2-inch (360 mm) rear rotors. Four-piston aluminum calipers provide increased stiffness to reduce fluid displacement and caliper deformation without adding weight. The result is an enhancement to braking feel and overall vehicle dynamics.
Electronic Brake Force Distribution optimizes control of rear brake pressure on all road surfaces and under all vehicle loading conditions. Electronic Brake Assist senses how hard and fast a driver depresses the brake pedal and gives extra braking assistance, if required.
The SS’s steering system employs a variable-assist electric power steering system that saves fuel by drawing energy only when the wheels are turned. The variable-effort design provides lighter parking efforts at low speed and greater effort at higher speeds, for a more direct steering feel. The system is also calibrated to detect constant driver steering wheel load due to factors such as road camber and crosswind. The system will compensate to reduce steering effort to a more neutral level and lessen potential driver fatigue.
The Chevrolet SS offers a comprehensive collection of standard safety features. It employs advanced technologies – including radar – to help avoid crashes. Visual and audible alerts, depending on the alert feature, help drivers identify potential crash situations. They are designed to identify potential threats with sufficient warning to give the driver time to react and make changes.
SS is also the first Chevrolet to offer Automatic Parking Assist, which provides hands-free parking help. This standard features uses an ultrasonic sensing system to detect the width and depth of either parallel or reverse right-angle parking spaces. While the driver controls the throttle, transmission and brake, Automatic Parking Assist controls the steering inputs necessary to park the vehicle.
The standard safety features on SS also include:
- Forward collision alert – Camera technology detects a possible crash threat and alerts the driver, giving him or her time to stop and/or change course.
- Lane departure warning – A camera-based lane detection system warns the driver of impending lane changes. The camera, mounted near the inside rearview mirror, identifies traffic lane markings and provides audible alerts.
- Side blind zone alert – Using radar sensors on both sides of the vehicle, the system “looks” for other vehicles in the blind zone areas of the SS and indicates their presence with LED-lit symbols in the outside mirrors.
- Rear cross traffic alert – Based on the radar sensors of side blind zone alert, it warns the driver of vehicles in traffic when backing out of a parking spot – including angled parking. Visual and audible alerts are triggered if moving vehicles are detected.
- Rear vision camera – With a display in the center stack infotainment system, the camera provides a view of objects directly behind the SS.
- Eight air bags to help to maximize protection in severe impacts while minimizing injury risk to out-of-position occupants, including driver/front passenger dual-stage air bags, knee air bags for driver and the front passenger, side air bags and roof rail side curtain air bags, for head protection for front and second-row occupants.
- StabiliTrak electronic stability control and full-function traction control.
