A following distance indicator is available in the 2019 model, but not the 2015. If these upgrades aren't important to you, then you may want to a look to a used model.

There's only one new luxury small car that has a base MSRP within the 2015 ATS' price range: the 2019 Acura ILX. It fares poorly in the class, but the ILX is still worth a look as an alternative to the 2015 ATS, if only because the ILX has more modern safety technology.

Which Model Year of the Cadillac ATS Is Best?

The ATS gained fresher exterior styling, a few new features, and the coupe body style for 2015. While the 2015 ATS is OK, most shoppers will prefer a newer model. For 2016, the ATS received an eight-speed automatic transmission, an updated CUE system with Apple CarPlay, and a performance-oriented trim called the ATS-V. Cadillac made their CUE infotainment system standard in every ATS for 2017, and the Teen Driver management system became standard. A great tool for parents, Teen Driver lets you do things like set speed and audio volume limits for secondary drivers.

How Safe Is the ATS?

The National Highway Traffic Safety Administration gave the 2015 ATS an overall rating of five out of five stars, with five stars in the frontal crash, side crash, and rollover tests.

2015 Cadillac ATS Versus the Competition

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

The 2015 Audi A4 finishes well ahead of the ATS in our luxury small car rankings. It has a stronger base engine, a better reliability rating, and a roomier cabin than the ATS. Unlike its Cadillac rival, the A4 comes standard with a sunroof and leather seats. On the other hand, the ATS has more available driver assistance features.

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

The 2015 Mercedes-Benz C-Class gets a poor reliability rating, but it's otherwise superior to the ATS. The Mercedes has a stronger and more fuel-efficient base engine, and it also touts 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 car has a complicated infotainment system.

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

The 2015 Cadillac CTS is a luxury midsize car that's essentially the ATS' big brother. Its two engine choices – a turbocharged four-cylinder and a V6 – are the same two engines that are optional in the ATS. The CTS is powerful and handles corners extremely well. Inside, these two are much the same, though the CTS has more space for passengers and cargo. If you need the extra room, the CTS is the better choice.

2015 ATS Performance

How Does the 2015 Cadillac ATS Drive?

You get a few different options when it comes to this Cadillac's engine. The ATS sedan comes with a 2.5-liter four-cylinder engine that puts out 202 horsepower and 191 pound-feet of torque. The ATS coupe features a turbocharged 2.0-liter four-cylinder that produces 272 horsepower and 295 pound-feet of torque, and this same powertrain is available in sedan models. Both body styles are available with a 3.6-liter V6 that produces 321 horsepower and 275 pound-feet of torque. All 2015 ATS models come standard with a six-speed automatic transmission. A six-speed manual is available in rear-wheel-drive models with the turbocharged engine.

The base engine gets the job done, but it's not particularly impressive by class standards. The turbocharged engine delivers much quicker acceleration and plenty of power, though it's also louder than the turbo-fours of some competitors. The V6 engine makes the ATS feel fast, but it doesn't feel appreciably stronger than the turbo-four.

This Cadillac handles curves with finesse, and its strong brakes and accurate steering make it enjoyable to drive. The ATS rides smoothly, particularly with the available Magnetic Ride Control suspension, which automatically adjusts to road condition for improved ride quality and sharper handling ability. Rear-wheel drive comes standard in the ATS, and all-wheel drive is available.

Does the 2015 Cadillac ATS Get Good Gas Mileage?

The ATS isn't as fuel-efficient as some of its classmates. With its base engine, this Cadillac gets 21 mpg in the city and 32 mpg on the highway. That drops to 21/29 mpg city/highway with the turbo-four engine (with the automatic transmission). The V6 brings up the rear at 18/27 mpg. Ratings drop slightly with all-wheel-drive models.

2015 ATS Interior

How Many People Does the 2015 ATS Seat?

The 2015 Cadillac ATS sedan seats five, while the coupe seats four. Standard features include synthetic leather upholstery and power-adjustable front seats. Available features include leather upholstery, heated front seats, and a heated steering wheel.

There are plenty of quality materials throughout the ATS' stylish cabin. The front seats are spacious, but the rear seats are a tighter squeeze. They feel particularly cramped in the coupe, but even in the sedan, tall adults will feel confined. Many rivals are more spacious overall.

How Many Child Car Seats Fit in the 2015 Cadillac ATS?

There are two full sets of LATCH connectors for installing child safety seats. Most types of car seats fit into the back seat relatively easily, and the tether anchors are easy to use. However, the lower anchors are difficult to access.

2015 Cadillac ATS Features

Standard features include dual-zone automatic climate control, push-button start, proximity keyless entry, Bluetooth phone connectivity, two USB ports, a seven-speaker Bose audio system, satellite radio, and a Wi-Fi hot spot.

Available features include a sunroof, wireless device charging, and Cadillac's CUE infotainment system, which has an 8-inch touch screen, navigation, Bluetooth audio streaming, HD Radio, and a 10-speaker Bose audio system.

The infotainment system has an intuitive voice command feature and a good navigation system. However, the screen's dark surface makes smudges easily noticeable. The touch-sensitive buttons vibrate when you press them, but these controls can be slow to respond to inputs.
