One of the most promising elements of the Cadillac ATS Coupe is that it adds platform rigidity and performance focus to this new contender in the hotshot exec coupe segment.
Two fewer doors does not cut the weight of the 2015 ATS Coupe much in launch 2.0T trims, but the performance focus is very clear from Cadillac.
The specs of both ATS Coupes look outstanding, and with as much or more tail-out grins than the 428i and 435i from BMW.
Correction coming soon: the red ATS Coupe photos shown here are off-color. These will be replaced soon. The real-life color is a darker shade.

Cadillac Introduces 2015 ATS Coupe
Cadillac’s first compact luxury Coupe, infused with ATS sedan’s agility
2.0L Turbo model is segment’s lightest, with increased torque for faster acceleration
Launching in summer 2014, continuing Cadillac’s ongoing expansion
DETROIT – Cadillac today introduced the all-new 2015 ATS Coupe, a quicker and more personal addition to the award-winning ATS product line. Designed to be 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.
Cadillac’s first-ever compact luxury Coupe goes on sale this summer, offering drivers the choice of rear-wheel drive or all-wheel drive, and the power from a 2.0L turbocharged four-cylinder or a 3.6L six-cylinder. In all combinations, ATS Coupe takes advantage of its lightweight and strong structure to deliver exhilarating performance with efficiency, with a segment-leading power-to-weight ratio.
“The 2015 Cadillac ATS Coupe is a natural step in the brand's progression, and another fun-to-drive and technologically advanced product for a new generation of drivers extending our target groups,” said Uwe Ellinghaus, chief marketing officer, Global Cadillac. “It is an exclusively distinctive American alternative, unique in its class, yet delivering a sporty and sophisticated driving experience rivaling the world's best.”
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 is upgraded from the current ATS sport sedan to deliver nearly 14 percent more torque, taking it to 295 lb-ft (400 Nm). This gives the standard ATS Coupe an advantage in power and weight over similarly equipped Coupes such as the BMW 428i.
Greater torque means greater pulling power, for a greater feeling of responsiveness at low speeds, and helps the ATS Coupe achieve an estimated 0-60 time of 5.6 seconds.
“More power with less weight is always a better combination for performance, and the ATS Coupe offers one of the best power-to-weight ratios in the segment, making it feel lighter, more direct and responsive,” said David Leone, Cadillac executive chief engineer. “Engineers vetted the ATS’s performance on the track, and the Coupe benefits from that exhaustive validation – all matched with Cadillac’s trademark refinement.”
Elements that contribute to the ATS Coupe’s balanced performance and responsive characteristics include:
Nearly perfect 50/50 weight balance and low center of gravity
Five-link independent rear suspension featuring lightweight, high-strength steel and efficient straight link designs
A multi-link double-pivot MacPherson-strut front suspension with direct-acting stabilizer bar
Underbody aerodynamic shields
Premium, belt-driven electric variable-effort steering gear from ZF Steering Systems
Brembo front brakes
Eighteen-inch aluminum wheels
Available all-wheel drive.
A driver-adjustable FE3 sport suspension is available and includes Magnetic Ride Control, a mechanical limited-slip differential, high-capacity engine cooling system and 18-inch summer-performance tires. Magnetic Ride Control is a real-time damping system that delivers more precise body motion control. It “reads” the road and can change damping every millisecond.
The 2015 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. It is also the first production model to wear Cadillac’s revised crest.
The Coupe also has an aggressive stance, with wider front/rear tracks than the sedan, enhanced by short overhangs and sheet metal that wrap tautly around the tires. Standard 18-inch wheels are exclusive to the Coupe.
Bold lighting elements are a Cadillac signature feature and the ATS Coupe advances that tradition with available light-emitting diode, or LED, headlamps with Adaptive Forward Lighting. Base models feature projector-beam headlamps, while high-intensity-discharge headlamps and front vertical LED light signatures are included on all but the standard model. Illuminating outside door handles on Performance and Premium collections lend technologically advanced style and function to the distinctive Coupe. All models feature LED taillamps and rear-center stop lamp.
The ATS Coupe also includes capless fueling.
Inside, the sedan’s driver-focused cabin carries over to the Coupe, featuring handcrafted cut-and-sewn upholstered interior combinations, decorative stitching and authentic materials, including leather, aluminum, carbon fiber and wood, intended to enhance the emotional connection to the driving experience.
Choices of many interior color themes, each with unique accent trim materials, ranging from light, open and warm to dark and serious, to bold technical and sporty.
Available interior features include:
OnStar 4G LTE connectivity with built-in Wi-Fi hotspot
Bluetooth phone and audio connectivity with natural voice recognition
Text-to-voice that converts incoming text messages to speech and reads them over the audio system speakers
USB, auxiliary and SD memory card ports
SiriusXM Satellite Radio with three-month trial subscription
Reconfigurable 5.7-inch, three-window instrument panel cluster display
Full-color reconfigurable head-up display.
A Bose ® premium audio system with Active Noise Cancelation technology is standard on all models and includes electronic sound enhancement on models equipped with the available premium surround sound audio system. Exclusive to ATS Coupe and differing from other manufacturers’ systems that pipe recorded engine sounds through the audio system; Cadillac’s system enhances only the car’s authentic powertrain sounds to enhance the performance experience.
The 12-speaker surround sound upgrade is available on Standard and Luxury, and it 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 make the most of the listening experience.
Additionally, a navigation system is available on Luxury and Performance collections, and it is standard with the Premium Collection.
Enhanced Cadillac CUE leads technologies
Cadillac CUE is the centerpiece of the ATS Coupe’s comprehensive collection of technologies designed to enhance the driving experience and complement customers’ increasingly connected lifestyles. It is available on base models and standard on Luxury, Performance and Premium collections, with enhanced connectivity and convenience for 2015, including a new Text-to-Voice feature for smartphone users with Bluetooth profile (M.A.P.) and Sire Eyes Free for iPhone iOS 6 and iOS 7 users to enhance connectivity and convenience. Each enables voice-controlled connectivity – and helps keep the driver’s hands on the wheel.
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 liquid crystal display, or LCD, screen resembles a smartphone screen with large, easy-to-target icons to execute commands.
Complementing CUE is OnStar 4G LTE connectivity, featuring a new built-in Wi-Fi hotspot that can connect up to seven devices at once. The new 4G LTE connection can also be used to power CUE Collection, a new in-car app marketplace coming to Cadillac vehicles this year.
Additional technologies that make life with the ATS Coupe more convenient include the capability to remotely start the engine or lower 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.
The engine lineup includes a standard 2.0L turbocharged four-cylinder and available 3.6L V-6. The award-winning 2.0L Turbo is rated at 272 horsepower (203 kW) and 295 lb-ft of torque (400 Nm). 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 2100 rpm to 5400 rpm and the full 295 lb-ft of peak torque (400 Nm) from 3000 to 4600 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 Coupe an exhilarating feeling of immediate power on demand.
Both 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 each is matched with the Hydra-Matic 6L45 six-speed automatic transmission with tap-shift control. A six-speed manual is also available with the 2.0L Turbo.
Advanced safety features
ATS Coupe delivers the same safety technologies found in the ATS Sedan. Additionally, Cadillac provides available advanced safety based on Cadillac’s “control and alert” strategy, which employs up to two cameras, eight ultrasonic sensors and six radar signals to help prevent crashes.
The safety features bolster driver vision and awareness of road hazards, and can even 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 to potential hazards.
Among the most sophisticated of the features is Fr ont 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 and Lane Keep Assist – new to Cadillac for 2015
Intellibeam ® high-beam control
Front and rear park assist
Rear-vision camera with dynamic guidelines.
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
Motorized safety belts
Electronic Park Brake
Front and Rear Automatic Braking
Enhanced Side Blind Zone Alert – new to Cadillac for 2015
Rear Cross-Traffic Alert
Full-color head-up display.
