2015 Cadillac ATS Overview

Is the 2015 Cadillac ATS a Good Used Car?

The ATS is a good fit for those who value swift acceleration and sharp cornering ability above all else. Still, some competitors offer impressive performance without sacrificing practicality.

Used 2015 Cadillac ATS Performance and Interior

The ATS comes with one of three powertrains. The standard 202-horsepower four-cylinder engine delivers mediocre power. Standard in the ATS coupe and available in the sedan, a turbocharged four-cylinder engine offers a welcome boost in acceleration, but it’s noisy and unrefined compared to competitors with turbo-four engines. The best of the bunch is the available V6, which puts out 321 horsepower and 275 pound-feet of torque. Fuel economy is typical for an upscale small car. Expect 18-21 mpg in the city and 26-32 mpg on the highway.

The ATS stands out as one of the nimblest cars in the class. The available magnetic ride control suspension improves handling ability and smooths out the ride, and the available Brembo brakes provide strong stopping power. Rear-wheel drive comes standard, and all-wheel drive is available. Most models feature a six-speed automatic transmission, but rear-wheel-drive models with the turbo engine can have a six-speed manual instead.

While the ATS sedan seats five, the coupe seats four. All models boast high-quality cabin materials, leatherette or leather upholstery, and power-adjustable front seats. Some models have heated front seats and a heated and power-adjustable steering wheel. The ATS’ front seats provide ample room, but the rear seats are too cramped for optimal comfort, even with the sedan. There are two complete sets of LATCH car-seat connectors on the rear outboard seats and a tether-only connection on the middle seat. The ATS’ 10.4-cubic-foot trunk is small by class standards.

The ATS comes standard with dual-zone automatic climate control, proximity keyless entry, a seven-speaker Bose audio system, and a Wi-Fi hot spot. The available CUE infotainment system employs an 8-inch display and touch-sensitive buttons, which respond slowly at times. The system’s complicated interface is overwhelming at first, but it gets easier to use with practice. Alternatively, voice recognition carries out many tasks more efficiently. Notable available features include remote start, a navigation system, a 12-speaker Bose audio system, a sunroof, and a wireless device charger.

How Safe Is the ATS?

The ATS earns confidence-inspiring safety scores. The National Highway Traffic Safety Administration gives the 2015 model a perfect five-star rating in all categories.

A rearview camera and Cadillac’s OnStar emergency notification system come standard. The ATS is available with nearly every advanced safety feature on the market, including adaptive cruise control, blind spot monitoring with rear cross traffic alert, a head-up display, front and rear parking sensors, lane departure warning, lane keep assist, forward collision warning, and automatic emergency braking. There’s also an available safety alert driver’s seat, which vibrates to warn you of potential dangers.

Should I Consider Another Used ATS?

Currently in its first generation, the Cadillac ATS debuted for 2013. The 2015 model year brings fresher exterior styling, a few new features, and the introduction of the Cadillac ATS coupe. For 2016, the ATS received a new eight-speed automatic transmission, an updated CUE system with Apple CarPlay, and a new performance-oriented trim called the ATS-V. Aside from these updates, the ATS has changed little over the years. You may want to take advantage of the savings that come with buying an older model that offers similar features.

Which Used Cadillac ATS Is Right for Me?

The 2015 ATS comes in four trim levels: Standard, Luxury, Performance, and Premium. Those looking for the best feature-to-dollar ratio should consider the Cadillac ATS Luxury. It comes with leather upholstery, a wireless device charger, and the CUE infotainment system with voice recognition.

Given the ATS’ below-average predicted reliability rating, you may want to consider a certified pre-owned model. Cadillac CPO vehicles see the original new-car limited warranty extended to six years or 100,000 miles. Cadillac CPO models must pass a 172-point inspection. Additional benefits like towing and roadside assistance may be available, so read Cadillac’s warranty page carefully.

2015 Cadillac ATS and Other Cars to Consider

Which Is Better: 2015 Cadillac ATS or 2015 Audi A4?

Available only as a sedan, the Audi A4 has a stronger base engine, a higher predicted reliability rating, and roomier seating than the ATS. Unlike its Cadillac rival, the A4 comes standard with a sunroof and leather seats. On the other hand, the ATS has sharper handling, more available driver assistance features, and better safety ratings. For a comparable Audi coupe, check out the Audi A5.

Which Is Better: 2015 Cadillac ATS or 2015 Mercedes-Benz C-Class?

The Mercedes-Benz C-Class was our 2015 Best Upscale Small Car for Families, and for good reason. Compared to the ATS, it has a stronger and more efficient base engine, an impressive reliability rating, and a show-stopping 469-horsepower Mercedes-AMG trim. Unlike the ATS, the C-Class features standard automatic emergency braking and a driver drowsiness monitor. On the downside, both come up short on rear-seat space, and each has a complicated infotainment system.

Which Is Better: 2015 Cadillac ATS or 2015 Cadillac CTS?

Like its smaller sibling, the Cadillac CTS is available as either a sedan or coupe. The CTS offers roomier rear seats, an above-average reliability rating, and a stronger base engine, which are a few reasons why it was our 2015 Best Upscale Midsize Car for Families. Fast-car fiends will want the CTS-V (only available as a coupe for the 2015 model year), a high-performance variant that puts out 556 horsepower. Conversely, the ATS appeals to shoppers who want nimbler small-car handling and a lower average price than the CTS.
