2015 Cadillac ATS Sedan unveiled with new crest, revised front styling

The Cadillac ATS lineup expands for 2015 with the all-new ATS Coupe. Lighter, more agile and more engaging than its competitors, it extends Cadillac's product-driven growth and the brand's tradition of dynamic luxury coupes – while the ATS Sedan continues to challenge the world's best premium cars with an acclaimed balance of performance and refinement, wrapped in a progressive expression of Cadillac's Art & Science design philosophy.

The new ATS Coupe – offered with 2.0L Turbo and 3.6L V-6 engines, in RWD or AWD – takes advantage of its lightweight and strong structure to deliver exhilarating performance with efficiency, with segment-leading standard torque and power-to-weight ratios when compared with comparable competitor offerings.

Like the sedan, the ATS Coupe's driving dynamics are rooted in mass efficiency, which helps make it one of Cadillac's lightest and most agile models ever – and the lightest car in the compact luxury coupe segment. The 2.0L Turbo engine offered in the Coupe and Sedan is upgraded to deliver nearly 14 percent more torque for 2015, taking it to 295 lb-ft (400 Nm). This gives the standard ATS Coupe an advantage in power and torque over similarly equipped coupes such as the BMW 428i.

Greater torque means greater pulling power, for a greater feeling of responsiveness at all speeds, and helps the ATS Coupe achieve an estimated 0-60 time of 5.6 seconds. Additional contributing components and features for Coupe and Sedan models include:

• Nearly perfect 50/50 weight balance
• Cadillac's first five-link independent rear suspension using lightweight, high-strength steel and efficient straight link designs
• A multi-link double-pivot MacPherson-strut front suspension with direct-acting stabilizer bar
• Available driver-adjustable FE3 performance suspension with Magnetic Ride Control real-time damping
• Underbody aerodynamic shields
• Premium (belt driven) electric variable-effort steering gear from ZF Steering Systems
• Brembo performance brakes – available on Sedan and standard on Coupe
• Available all-wheel drive.

The ATS lineup is offered as well-equipped Standard models, as well as Luxury, Performance and Premium Collections. A broad lineup of engines – including two four-cylinders and a V-6 for North America – delivers strong power to the ATS and capitalizes on the car's lightweight and rigid structure to complement its performance with efficiency. The optional engines include Cadillac's award-winning 2.0L Turbo, rated at 272 horsepower (203 kW) and a 3.6L V-6, rated at 321 horsepower (239 kW).

ATS design and exterior features
The new ATS Coupe rides on the same 109.3-inch (2,775 mm) wheelbase as the sedan, but features its own bodywork. The roof, doors, rear fenders and trunk lid are unique to the Coupe, along with a specific front fascia and front fenders that accommodate a wider track than the Sedan.

The unique front appearance introduced on the ATS Coupe is shared by the 2015 Sedan models, all incorporating Cadillac's new crest on the grille. Both body styles have a firmly planted stance, enhanced by short overhangs and taut sheet metal that appear to wrap tightly around the tires. Seventeen-inch wheels are standard on ATS Sedan and 18-inch wheels are standard on ATS Coupe.

The ATS Coupe also includes capless fuel fill.

Bold lighting elements are a Cadillac signature feature and the ATS advances the tradition with available high-intensity discharge (HID) headlamps, light-emitting diode (LED) vertical light signature elements and Adaptive Forward Lighting. The Standard model features projector-beam halogen headlamps, while the HID headlamps and front vertical LED light signatures are included on all collections above the Standard model on Coupe, and on the Performance and Premium Collections for Sedan. Illuminated outside door handles on Performance and Premium Collections lend technologically advanced style and function. All models feature LED technology for the taillamps and rear-center stop lamp.

The Intellibeam feature – included with the Driver Awareness or Driver Assist packages – automatically deploys high-beam headlamps when needed and instantly turns them down when oncoming traffic is detected.

Seventeen-inch premium painted aluminum wheels are standard on the Sedan, with 17-inch polished and 18-inch forged machined-face and polished wheels available. Nineteen-inch wheel-and-tire combinations are available as dealer-installed accessories. A range of 18-inch premium painted, machined or polished wheels is available on the ATS Coupe.

Exterior colors: Red Obsession Tintcoat, Phantom Gray Metallic, Majestic Plum Metallic, Dark Adriatic Blue Metallic, Radiant Silver Metallic, Black Raven, Black Diamond Tricoat, Crystal White Tricoat, Opulent Blue Metallic and Silver Coast Metallic.

ATS interior features
A driver-focused interior with integrated technology and crafted materials complements the exterior elements and supports the ATS's driving experience. Everything from the placement of the pedals to the position of the shifter is designed for effortless and intuitive performance driving. Available performance seating includes power-adjustable bolsters to optimize lateral support during high-load cornering.

Contributing to the interior's intuitive feel is an instrument panel that wraps into the doors and a center stack in the mid-instrument panel that flows into the center console. LED lighting within the bold gauge cluster enables clear, at-a-glance viewing in all lighting conditions, while ambient lighting accents functional elements of the console and doors.

Real wood, metal plating and carbon fiber trim and Cadillac's cut-and-sewn instrument panel, console and doors enhance the emotional connection to the ATS. Choices of many interior environments, each with unique accent trim material, cover a wide range of flavors – from light, open and warm to dark and serious, bold, technical and sporty.

Interior color and trim choices are offered in four levels:

Level 1 – Light Platinum/Black with Oil Rubbed Bronze-appearance trim (Sedan only) or Black/Black with Oil Rubbed Bronze-appearance trim on Sedan and High Gloss Okapi Stripe designer wood trim on Coupe. Leatherette seating surfaces

A Bose® premium audio system with Active Noise Cancelation technology is standard on all models and on ATS coupe; it includes electronic sound enhancement when equipped with the available premium surround sound audio system. It differs from other manufacturers' systems that pipe recorded engine sounds through the audio system. ATS electronic sound enhancement enhances only the car's authentic powertrain sounds to support the performance experience.

A 12-speaker surround sound upgrade is available on Standard and Luxury, and is included with Performance and Premium collections. It includes Bose Audio Pilot, which continuously monitors ambient sounds and adjusts the music volume and program content to optimize the listening experience.

Additionally, a navigation system is also available on Luxury and Performance collections, and it is standard with the Premium Collection.

Enhanced Cadillac CUE and new OnStar 4G LTE
Cadillac CUE is the centerpiece of the ATS's comprehensive collection of technologies designed to enhance the driving experience and complement customers' increasingly connected lifestyles. It is available on Standard models and included on Luxury, Performance and Premium Collections, with enhanced connectivity and convenience for 2015, including a new Text Message Alerts feature for smartphone users with Bluetooth profile (M.A.P.) and Siri Eyes Free for iPhone iOS 6 and iOS 7. Each enables voice-controlled connectivity – and helps keep phones stored and hands on the wheel.

The new Cadillac DockSpot magnetic inductive charging system (late availability) is a wireless phone charger that allows users to simply place their phone on a small mat in the ATS, where it charges without the need to plug it in.

The heart of CUE is the eight-inch LCD multi-touch sensitive screen, integrated into the top of the central instrument panel and featuring a motorized, fully capacitive faceplate at the bottom concealing a 1.8L storage area. CUE's vibrant LCD screen resembles a smartphone's screen, with large, easy-to-target icons to execute commands.

Complementing CUE to enhance the ATS'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 three-month/three-gigabyte data trial.

4G LTE is the most current and fastest mobile data network – 10 times faster than 3G and 100 times faster than the previous generation of OnStar hardware. 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, simplifying service scheduling.

Additional technologies that make life with the ATS more convenient include the capability of remotely starting the engine or lowering the windows with the key fob or the owner's smartphone. EZ Key passive entry and push-button starting is standard, too, so the key never needs to leave the driver's pocket or purse.

ATS powertrains
The engine lineup includes a 2.5L four-cylinder standard on some Sedan models, a 2.0L turbocharged four-cylinder available on Sedan and standard on Coupe; and a 3.6L V-6 available on Sedan and Coupe. The four-cylinder engines were designed and developed specifically for the ATS, with the 2.0L Turbo offered with a manual transmission – a choice unavailable with many luxury competitors.

The 2.5L is rated at 202 horsepower (151 kW) and 191 lb.-ft. or torque (259 Nm), while the award-winning 2.0L Turbo is rated at 272 horsepower (203 kW) and 295 lb-ft of torque (400 Nm) – a nearly 14-percent increase over 2014 models. The award-winning 3.6L V-6 is rated at 321 horsepower (239 kW) and 275 lb-ft of torque (373 Nm).

At 136hp/L, the 2.0L Turbo is one of the most power-dense engines in the industry, topping engines from European competitors. It also delivers 90 percent of its peak torque from 2,100 rpm to 3,000 rpm and the full 295 lb-ft of peak torque (400 Nm) from 3,000 to 4,600 rpm. The broad torque band is supported by boost levels as high as 18 psi (1.26 bar) in the speed range, which is designed to give the lightweight ATS an exhilarating feeling of immediate power on demand.

All of the engines feature direct injection and dual overhead camshafts with continuously variable valve timing, which help optimize power and efficiency, as well as reduce emissions. And all of the engines are matched with six-speed transmissions, including the Hydra-Matic 6L45 automatic with tap-shift control, and a TREMEC six-speed manual available with the 2.0L Turbo.

ATS driving experience
Proportion and balance are on the ATS's side, with a low curb weight and power-dense powertrains that are also lightweight, enabling a nearly perfect 50/50 weight distribution and excellent power-to-weight ratios. They complement wide front and rear tracks – including wider tracks on ATS Coupe – and a low center of gravity, promoting greater stability.

Low vehicle mass and optimal brake sizes give the ATS braking performance that is among the best in the segment, with Brembo brakes contributing to 60-0 performance of approximately 129 feet (39.3 meters).

Up front, a multi-link MacPherson strut suspension uses a double-pivot design for a more precise feeling of control, including more linear and communicative steering, and a smoother ride. It also improves impact isolation on bumps and rough surfaces.

The double-pivot system incorporates a pair of ball joints and lower control links that replace a conventional wishbone at each wheel. The optimal balance of ride and handling is achieved via a suspension geometry that decouples road inputs by integrating a soft fore/aft "ride link" that provides greater isolation from impacts and a stiff, laterally positioned "handling link" for more direct steering feel and quicker lateral response.

The control arms, the spindle and the body form an effective four-bar link for each side of the front suspension, creating virtual pivot points with reduced spindle length, significantly reducing steering wheel feedback due to wheel impacts. There is also a direct-acting stabilizer bar.

The front suspension's design also enables a shorter spindle and positive-offset steering geometry for optimal steering control, excellent straight-line stability and a more refined ride. High-durometer rubber and hydraulic bushings are used with the front suspension for an excellent balance of ride comfort and precise response when cornering.

At the rear of the ATS is the first five-link independent suspension in a Cadillac. The design helps reduces roll center motion, enables positive lateral control, reduces "squat" during acceleration and promotes excellent dynamic stability. In short, it helps keep the tires planted on all surfaces and during all hard-cornering maneuvers.

Four handling links (upper and lower control arms) are used at each side to control wheel motion and a toe link at each wheel provides additional horizontal control – particularly during hard cornering. The upper and lower links create an effective double-wishbone design, although the links are mounted independently. As with the front suspension, the five-link design creates virtual pivot points that the ATS's engineers used for geometry optimization. The stiff links are mounted on a cradle that contributes to a smoother, quieter and more isolated ride. The cradle is made of steel (with hydroformed side rails) to help optimize the car's structural stiffness and mass.

On the Sedan, 17-inch wheels are standard, with 18x8-inch wheels available – all matched with 225/40-series tires. The available FE3 Performance Suspension features wider 18x9-inch rear wheels with 255/35 tires (all FE3 tires are summer-only). On the Coupe, 18x8-inch front (225/40 tires) and 18x9 inch rear wheels (255/35 tires) are standard. As with Sedan, the Coupe's FE3 Performance Suspension includes summer-only tires.

The mechanical limited-slip differential feature is not matched by all other competitors and gives the ATS an edge when it comes to ensuring all of the powertrain's torque is applied to the tires during hard cornering. It is standard with the six-speed manual transmission and included with the FE3 Performance Suspension. It is housed in a robust 8.6-inch carrier. Other models feature a 7.67-inch carrier.

Supporting the ATS's suspensions are advanced damping, steering and braking systems, including Magnetic Ride Control (MRC), which is the heart of the FE3 Performance Suspension (included on the RWD Premium Collection) – and also includes a mechanical limited-slip differential, high-capacity engine cooling system and 18-inch summer-performance tires. MRC is a real-time damping system that delivers more precise body motion control. It "reads" the road and can change damping every millisecond.

Selectable driver mode settings are standard and include Sport, Touring and Snow/Ice (automatic transmission only). On FE3-equipped vehicles, each mode is optimized for Magnetic Ride Control damping, as well as transmission shift algorithms and stability control and traction control system intervention.

All models come with an electric, variable-assist power steering system from ZF Steering Systems. It is designed to deliver excellent response and on-center characteristics, while also saving fuel because engine power isn't directly required to assist gear movement – as is the case with conventional hydraulic systems.

The ZF steering gear has great torsional stiffness and low operating friction, which enhance the steering feel with almost perfect linear response. Additionally, the steering column and intermediate shaft feature stiff, direct-acting and low-friction ball bearing designs. That means there is almost no "lash" in the entire steering system, for a more immediate and connected-to-the-road feel for the driver.

Four-wheel disc brakes – with patented rotor coating protection and auto-dry functionality – are standard. Brembo performance front brakes are standard on Coupe and standard on all Sedan Collections above the Standard model, where they are available. They are matched with a four-channel ABS system integrated with standard StabiliTrak stability control and full-function traction control.

ATS's available all-wheel-drive system is designed to make the most of handling and stability in all driving conditions. It is an advanced, fully automatic and on-demand system that includes wheel-slip management.

Advanced safety features
ATS provides standard NHTSA 5-Star all-around and overall crash safety ratings (Sedan model tested), the highest safety ratings available.

In addition, Cadillac provides available advanced safety based on Cadillac's "control and alert" strategy that employs advanced technologies – including radar, cameras and ultrasonic sensors – to help prevent crashes. The safety features bolster driver vision and awareness of road hazards, and can even assist to help the driver avert potential crashes. In certain situations, Cadillac's advanced crash-avoidance systems, such as automatic braking, can pre-fill and automatically apply braking in response in certain situations.

Among the most sophisticated of the features is front and rear automatic braking. It relies on radar, camera and ultrasonic technology to help the driver prevent front and rear low-speed collisions via a progression of alerts that extend to complete braking, if necessary.

Many of the advanced safety features are bundled in the Driver Awareness and Driver Assist Packages. The Driver Awareness Package is available on Luxury and included in Performance and Premium Collections. It includes:

• Safety alert seat
• Forward collision alert
• Lane departure warning
• Lane keep assist
• Intellibeam® high-beam control
• Rainsense wipers
• Rear thorax air bags (sedan models).

The Driver Assist Package is available on Performance and Premium collections and includes all of the Driver Awareness Package content, plus:

• Full-speed range adaptive cruise control
• Automatic collision preparation
• Automatic safety belt tightening
• Electronic park brake
• Front and rear automatic braking
• Side blind zone alert
• Rear cross-traffic alert
• Full-color head-up display.

The advanced technologies complement the ATS's other safety features, including eight standard air bags (10 available on sedan with Driver Awareness and Driver Assist Packages), safety belt pretensioners and load limiters, StabiliTrak electronic stability control system with full-function traction control and four-wheel disc brakes with four-channel ABS, patented rotor coating protection and auto-dry functionality. Hill Hold/Start assist is also standard on ATS with both automatic and manual transmissions; and front/rear park assist is standard on all except Standard models.

A rearview camera system with dynamic guideless is included with CUE on Sedan models (available on Standard and included with other Collections) and standard on Coupe.
