The Cadillac ATS sedan is a popular high-performing choice for luxury car fans. The latest year of this sedan model is 2018.

The attractive ATS sedan is a favorite in the luxury car class. It provides an American-made option that competes with German brands like BMW and Mercedes-Benz.

The Cadillac ATS sedan offers three engine choices, including a V6 engine that puts out 335 hp. You can pair it with an all-wheel drive and a six-speed manual transmission.

This Caddy has an 8-inch touchscreen that lets you navigate its infotainment system, and great features like Android Auto and Apple CarPlay are available. A 4G LTE Wi-Fi hotspot that uses a subscription service is also available to keep you connected.

Using well-designed angular sheet metal, the ATS sedan is at the top of its class when it comes to style. On fuel efficiency, it holds its own while performing well and sounding good.

You can choose either the eight-speed automatic transmission or the six-speed manual transmission. The solid responsiveness and precision of the manual are favorites among ATS fans.

When accelerating, you can shift from one gear to the next with ease. The clutch is easy to use, too.

The 2018 Cadillac ATS sedan is one of the best luxury cars when it comes to handling, according to experts in the industry. Fans will appreciate the sheer athleticism of the ATS as its handling is like that of an actual sports car. When you select the V-Sport Performance Suspension Upgrade, you get even better tires and a sport-tuned suspension.

The ATS's sound system provides a wonderful music-listening and podcast experience. The 10-speaker Bose sound system offers rich, deep bass and a lack of sound distortion. With a sound system like that, your daily commute becomes a lot more appealing.

If your teenager will be driving your ATS at any point, you need to know about Teen Driver Mode. This helpful feature allows parents to track their teen driving habits and locations. You can also use this feature to establish a top speed for new drivers.

According to federal government data, the 2018 Cadillac ATS did well in key crash tests. With a wide array of safety features and technology, the ATS is a safe choice of vehicle. You can select great safety features, including a backup camera and GM's award-winning OnStar emergency service.

The ATS isn't faster or more efficient than other cars in its class. It doesn't outperform peers like the Audi A4, BMW 3 Series, or the Mercedes-Benz C-Class. Still, there's enough here, including a reasonable price, that should entice you to take a closer look at the Cadillac ATS sedan.

Cadillac ATS Sedan Exterior Design

With its distinctive appearance, the Cadillac ATS stands out from other sporty sedans. Its styling is unique from its angular headlamps to its sharp body lines. The Carbon Black trim level, in particular, gives the ATS an untamed road presence that many will love.

Cadillac ATS Sedan Interior Design

The ATS sedan can seat up to five people in comfy front seats that you can upgrade with heat, leather, or power. There's limited space in the back seat, but it's still more than you would get with other car models in its class. The rear outboard seats have three tether anchors, and there's enough room to fit most car seats there.

The materials used in the cabin are nice, giving it a modern feel. The nice faux leather comes standard with lots of available upgrade options, such as leather, inlays, carbon fiber trim, and more. There is 10.4 cubic feet of trunk space, which is on the low side when compared to its peers.

The High-Performing ATS-V

The ATS-V is the most expensive of the trim levels. While it's more than some shoppers are willing to invest, the available options may be well worth it for those interested in performance and comfort upgrades. At a mediocre 17 mpg for city driving and 25 mpg on the highway, however, the ATS-V has a lower fuel economy than the standard ATS.

When it comes to performance, the ATS-V model is at the top of its class. Equipped with an amped-up V6 engine that puts out 464 hp, the acceleration is at a different level. With its powerful engine and various performance upgrades, the ATS-V can go from 0 to 60 mph in 3.8 seconds.

Cadillac ATS Sedan Drawbacks

The ATS has a few drawbacks. The space inside the cabin is a little tight, particularly in the back seat area. The trunk offers a limited amount of space.

The four-cylinder engine can make a coarse, rasping sound at higher RPMs. The CUE (Cadillac User Experience) system includes a touchscreen that can be slow and confusing. A few of the interior controls, meant to be ergonomic and smart, aren't all that functional.

What Technology Does the Cadillac ATS Sedan Offer?

The ATS comes with an 8-inch touchscreen and a system that works pretty well. The audio and climate controls can be tricky on occasion. The buttons under the screen are touch-sensitive and can be a little distracting.

There are tech options available to add. These include Android Auto, Apple CarPlay, a Wi-Fi hotspot, a premium stereo, and USB ports.

What Safety Features Does the Cadillac ATS Sedan Offer?

The standard ATS has safety features such as the Teen Driver system, parking sensors, safety alert seats, and more. You also get alerts for lane change, blind-spot monitoring, forward collision, and rear cross traffic. There's even rain-sensing windshield wipers, auto high beams, adaptive cruise control, and more.

Should You Buy a New or Used Cadillac ATS Sedan?

If a brand-new car isn't a must for you, you can save a lot of money by considering a quality 2017 model. Older models in good condition can get you big savings as long as you know the year-to-year changes as you shop. The touchscreen first appeared as a standard feature in 2017, so you'll still have that option if you go with the older model.

A 272-hp turbocharged engine replaced the 202-hp motor in the standard car in 2017. In 2016, the popular ATS-V model appeared, and the eight-speed automatic transmission became standard. Android Auto and Apple CarPlay also became available that year in the Cadillac ATS sedan.

Model History

ATS became part of the Cadillac brand in 2012 as a new entry-level, high-end compact car. Using great driving dynamics, the ATS competes with the BMW 3 Series and the Mercedes Benz C-Class. The basic car was rear-wheel drive with all-wheel-drive available as an option.

Cadillac has a long history of offering cars that compete very well in the luxury class. The ATS line was designed to meet the nexus of luxury quality and sport performance, a combination that fits well with younger or more adventurous drivers. The smaller size and high-performance response add to those selling points.

The ATS offers three engine choices: a naturally aspirated four-cylinder, a turbocharged four-cylinder, and a powerful V6. The outer design of the ATS sedan became so popular that it inspired design features used on the Escalade SUV and the CTS line of Cadillac sedans.

In 2015, the sedan's front end got an update with a bigger Cadillac logo. Other additions included OnStar service, 4G LTE and Wi-Fi hotspot, and the CUE system. The V6 engine's output went up to a respectable 335 hp in 2016, and the Cadillac ATS Sedan added an eight-speed automatic transmission for boosted performance.
