Best Cadillac ATS Model Years (Ranked)

📖 2,290 words🗓️ Published Jun 22, 2026 · Updated Jun 21, 2026

The Cadillac ATS was Cadillac's compact sport sedan and coupe from 2013 to 2019, built squarely to challenge the BMW 3 Series on its own terms. Riding on the rear-drive Alpha platform, the ATS earned praise for genuinely excellent handling, a near-perfect weight balance, and crisp steering that few American sedans had matched. Engine choices ranged from a 2.0L turbo four and a base 2.5L four to a 3.6L V6, topped by the fire-breathing ATS-V with its 464-hp twin-turbo V6. The trade-offs were a cramped rear seat and the early CUE infotainment system. This ranking covers the best ATS model years, their powertrains, the issues to verify, and where the value lies today.

Direct Answer

The best overall Cadillac ATS is the 2016-2018 2.0L turbo, which benefits from a more powerful 272-hp version of the turbo four, an updated eight-speed automatic, refined chassis tuning, and improvements to the once-frustrating CUE infotainment system. For shoppers focused on value, the best value is the 2013-2015 3.6L V6, which delivers 321 hp, a smooth naturally aspirated character, and rear-drive balance at a now-low used price. Enthusiasts with bigger budgets should chase the 2016-2019 ATS-V, the ultimate version. Be cautious with very early 2013 models for first-year CUE glitches and minor electronics bugs, and always confirm timing-related service on turbo four-cylinder cars.

*Note: Prices vary significantly based on condition and market; these are representative of the model's typical market positioning.*

1. 2016-2018 2.0L Turbo 🏆 BEST OVERALL

2016-2018 2.0L Turbo

The mid-cycle ATS is the sweet spot. For 2016 the 2.0L turbocharged four was bumped to 272 horsepower and 295 lb-ft of torque, paired with a smooth eight-speed automatic that replaced the earlier six-speed. Cadillac also addressed many early complaints, improving the CUE infotainment responsiveness and refining ride and noise isolation. The result is a sharp-handling, rear-drive (or available all-wheel-drive) sport sedan that feels genuinely premium and engaging. Reliability is solid for these years when maintained, and used pricing is reasonable. For most buyers, a clean 2016-2018 2.0T in Luxury or Premium trim is the smartest, most rounded ATS to own.

2. 2013-2015 3.6L V6 💎 BEST VALUE

2013-2015 3.6L V6

The naturally aspirated V6 ATS is the value champion. The 3.6L V6 produces 321 horsepower with a linear, free-revving character that many drivers prefer over the turbo four, and it pairs beautifully with the rear-drive Alpha chassis. These early V6 cars are now affordably priced on the used market, undercutting comparable BMW 335i and Audi A4 examples. The best value is a 2014-2015 3.6L Premium or Performance trim, which adds leather, navigation, and upgraded audio. The V6 avoids any turbocharger complexity, and with regular maintenance it is a durable, satisfying engine. Excellent balance and strong power make this the smart budget enthusiast pick.

3. 2016-2019 ATS-V

2016-2019 ATS-V

The ATS-V is the high-performance halo and the most thrilling ATS to drive. Its 3.6L twin-turbocharged V6 makes a ferocious 464 horsepower and 445 lb-ft, sending the sedan or coupe to 60 mph in around 3.9 seconds with an available six-speed manual or eight-speed automatic. It adds Magnetic Ride Control, an electronic limited-slip differential, Brembo brakes, and aggressive aero. It is a legitimate BMW M3 rival and a future collectible, especially the manual coupe. Reliability is good for a performance car, though buyers should verify hard-use history and cooling-system condition. Budget for premium fuel and tires, and you get a genuinely special American sport sedan.

4. 2017-2018 3.6L V6

2017-2018 3.6L V6

The later 3.6L V6 ATS pairs the strong naturally aspirated engine with the eight-speed automatic and the refined chassis and updated CUE of the post-2016 cars. With 335 horsepower in this revised tune, it is quick, smooth, and engaging, and the rear-drive balance remains a highlight. These are well-equipped, premium-feeling sedans and coupes that hold up well. For a buyer who wants V6 power with the later interior and transmission improvements, a clean 2017-2018 3.6L in Premium trim is an excellent, low-stress choice that splits the difference between the early V6 value and the newest cars.

5. 2019 2.0L Turbo (Final Year)

2019 2.0L Turbo (Final Year)

The 2019 model year was the ATS sedan's last, with the lineup narrowing as Cadillac transitioned to the CT4. The 2.0L turbo carried over with 272 horsepower, the eight-speed automatic, and the most mature version of the CUE system and chassis tuning. As the newest used examples, 2019 cars carry the longest remaining warranty and the freshest condition, typically at a modest premium. Buy this one if you want the final, most refined ATS sedan with the latest updates. The handling and premium feel remain class-competitive, and low-mileage final-year cars are appealing long-term keepers.

6. 2015 2.0L Turbo

2015 2.0L Turbo

The 2015 2.0L turbo is the strongest of the early turbo cars, benefiting from minor running improvements over the 2013-2014 models while still using the six-speed automatic in most configurations. With 272 horsepower available and the lively Alpha chassis, it is engaging to drive and now sits at an attractive price point. Buyers should confirm the CUE system behaves and check for any timing-chain or turbo-related service history. For a value-minded shopper who wants the turbo four rather than the V6, a clean, well-documented 2015 2.0T offers most of the ATS appeal for less money than the post-refresh cars.

7. 2014 3.6L V6

2014 3.6L V6

The 2014 3.6L V6 is a strong early-generation pick, offering the smooth 321-hp naturally aspirated engine and excellent rear-drive dynamics at some of the lowest ATS prices today. By 2014 Cadillac had quietly addressed a handful of first-year niggles, making it a slightly safer bet than the launch 2013 cars. The interior is handsome, if tight in the rear, and the CUE system of this era is the main thing to test before buying. For a budget enthusiast who prioritizes the V6's character and the chassis over the latest tech, a clean 2014 3.6L Performance trim is a rewarding choice.

8. 2016-2018 2.5L Base Four

2016-2018 2.5L Base Four

The base 2.5L naturally aspirated four-cylinder offered the lowest entry price into ATS ownership, making roughly 202 horsepower. It is the least powerful and least engaging engine, lacking the turbo's torque and the V6's smoothness, and it is best suited to buyers who simply want the ATS look, chassis, and premium interior at the cheapest cost. On the plus side, it is mechanically simple with no turbocharger to worry about. Only choose the 2.5L if budget is the priority, since the 2.0T delivers far more performance for a small price difference and is the better all-round used buy.

9. 2013 2.0L Turbo (Caution)

2013 2.0L Turbo (Caution)

The 2013 2.0L turbo launched the ATS and earned acclaim for handling, but as a first-model-year car it carries the most risk. Early examples were prone to CUE infotainment glitches, minor electronics bugs, and the occasional teething issue that later years resolved. The 272-hp turbo four with the six-speed automatic is enjoyable, but the dated CUE and first-year quirks make it a cautious buy. Purchase one only with documented service and a thorough infotainment and electronics check. For most shoppers, stepping up to a 2015 or post-2016 turbo car is well worth it for the refinements and fewer headaches.

10. 2013 2.5L Base Four

2013 2.5L Base Four

The original 2.5L base four from the launch year is the least desirable ATS to seek out, combining the weakest 202-hp engine with the first-year CUE and electronics concerns. It exists mainly as the cheapest possible entry into the ATS, and survivors are typically high-mileage or stripped-down examples. There is little reason to choose one over a 2.0T or V6 unless the price is exceptionally low and the condition is excellent. Treat any 2013 2.5L as budget transportation, verify the CUE system and all electronics work, and confirm a clean maintenance record before buying.

What to Watch For When Buying

The single most important step when buying a used ATS is to thoroughly test the CUE infotainment system, especially on 2013-2015 cars, since early CUE units were slow and prone to unresponsive or cracked touch-capacitive controls. Confirm the screen, climate controls, and Bluetooth all function. On turbo-four cars, check for timing-chain noise and any turbocharger or oil-consumption history, and verify the engine has documented oil changes on schedule. For the V6 and ATS-V, inspect cooling-system condition and look for signs of hard use, particularly on the V. Across all models, test the eight-speed (post-2016) or six-speed automatic for smooth shifts, check for the typical cramped rear-seat fit if you carry passengers, and verify all driver-assistance and electronics work. A clean, documented service history outweighs a low sticker every time.

How to Choose

Match the ATS to your priorities. For the best blend of refinement, performance, and value, a 2016-2018 2.0T is the answer, with the stronger 272-hp engine, eight-speed automatic, and improved CUE. For the best value with classic naturally aspirated character, the 2013-2015 3.6L V6 is hard to beat at today's used prices. Enthusiasts who want the ultimate ATS should target a 2016-2019 ATS-V, ideally the manual coupe. Buyers wanting the final, most refined sedan should look at a 2019 2.0T. In every case, test the CUE system carefully, confirm turbo and timing service on four-cylinders, and prioritize a clean maintenance history over the lowest price.

FAQ

What is the best Cadillac ATS model year to buy? The 2016-2018 2.0L turbo models are widely considered the best overall. They feature a more powerful 272-hp engine, an improved eight-speed automatic, and refinements to the CUE infotainment system that address earlier complaints.

Are early Cadillac ATS years reliable? Early 2013 models can have first-year CUE glitches and minor electronics bugs, but many issues were resolved by 2014. The 2013-2015 3.6L V6 is a solid value if you verify service history, especially for timing chain maintenance.

Which ATS engine is most reliable? The 3.6L V6 is generally considered the most reliable, offering a smooth naturally aspirated character without the turbocharger complexity. However, the 2.0L turbo is also dependable if its timing-related service is kept up to date.

Is the ATS-V worth the higher price? Yes, for enthusiasts who want track-ready performance. The 2016-2019 ATS-V delivers 464 hp from its twin-turbo V6, with sharper suspension and brakes. It commands a premium but offers a genuine BMW M3 competitor.

How is the rear seat space in the ATS? The rear seat is cramped, especially for taller passengers. It’s one of the main trade-offs of the ATS, making it less practical than some rivals like the BMW 3 Series or Audi A4.

What should I check before buying a used ATS? For turbo models, confirm that timing chain and water pump service was done. For any ATS, test the CUE system for responsiveness, and check for any electrical gremlins. A pre-purchase inspection is recommended.

Bottom Line

The Cadillac ATS is an underrated used compact sport sedan that genuinely rivals the BMW 3 Series on driving dynamics, but model-year and engine choice matter. The 2016-2018 2.0L turbo is the best overall pick, with its stronger engine, eight-speed automatic, and improved CUE, while the 2013-2015 3.6L V6 offers the best value. Enthusiasts should chase the ATS-V, and bargain hunters should test early CUE systems carefully. Buy a clean, documented example and the ATS delivers premium feel, sharp handling, and rear-drive fun at a price that undercuts its German rivals.

On turbo-four cars, **check for timing-chain noise and any turbocharger or oil-consumption history**, and verify the engine has documented oil changes on schedule. For the V6 and ATS-V, inspect cooling-system condition and look for signs of hard use, particularly on the V. Across all models, test the eight-speed (post-2016) or six-speed automatic for smooth shifts, check for the typical cramped rear-seat fit if you carry passengers, and verify all driver-assistance and electronics work. A clean, documented service history outweighs a low sticker every time.

## How to Choose

Match the ATS to your priorities. For **the best blend of refinement, performance, and value**, a 2016-2018 2.0T is the answer, with the stronger 272-hp engine, eight-speed automatic, and improved CUE. For **the best value with classic naturally aspirated character**, the 2013-2015 3.6L V6 is hard to beat at today's used prices. Enthusiasts who want **the ultimate ATS** should target a 2016-2019 ATS-V, ideally the manual coupe. Buyers wanting **the final, most refined sedan** should look at a 2019 2.0T. In every case, test the CUE system carefully, confirm turbo and timing service on four-cylinders, and prioritize a clean maintenance history over the lowest price.

## FAQ

**What is the best Cadillac ATS model year to buy?**  
The 2016-2018 2.0L turbo models are widely considered the best overall. They feature a more powerful 272-hp engine, an improved eight-speed automatic, and refinements to the CUE infotainment system that address earlier complaints.

**Are early Cadillac ATS years reliable?**  
Early 2013 models can have first-year CUE glitches and minor electronics bugs, but many issues were resolved by 2014. The 2013-2015 3.6L V6 is a solid value if you verify service history, especially for timing chain maintenance.

**Which ATS engine is most reliable?**  
The 3.6L V6 is generally considered the most reliable, offering a smooth naturally aspirated character without the turbocharger complexity. However, the 2.0L turbo is also dependable if its timing-related service is kept up to date.

**Is the ATS-V worth the higher price?**  
Yes, for enthusiasts who want track-ready performance. The 2016-2019 ATS-V delivers 464 hp from its twin-turbo V6, with sharper suspension and brakes. It commands a premium but offers a genuine BMW M3 competitor.

**How is the rear seat space in the ATS?**  
The rear seat is cramped, especially for taller passengers. It’s one of the main trade-offs of the ATS, making it less practical than some rivals like the BMW 3 Series or Audi A4.

**What should I check before buying a used ATS?**  
For turbo models, confirm that timing chain and water pump service was done. For any ATS, test the CUE system for responsiveness, and check for any electrical gremlins. A pre-purchase inspection is recommended.

## Bottom Line

The Cadillac ATS is an underrated used compact sport sedan that genuinely rivals the **BMW 3 Series** on driving dynamics, but model-year and engine choice matter. The **2016-2018 2.0L turbo is the best overall pick**, with its stronger engine, eight-speed automatic, and improved CUE, while the **2013-2015 3.6L V6 offers the best value**. Enthusiasts should chase the **ATS-V**, and bargain hunters should test early CUE systems carefully. Buy a clean, documented example and the ATS delivers premium feel, sharp handling, and rear-drive fun at a price that undercuts its German rivals.
