Best Mazda6 Model Years (Ranked)
The Mazda6 was the brand's mid-size sedan from 2003 until it left the US market after 2021, and across three generations it consistently offered the most engaging drive and the nicest interior in a segment dominated by appliances. The third generation in particular grew into a near-luxury sport sedan, especially once the turbocharged 2.5-liter engine arrived.
Now fully on the used market, the Mazda6 is one of the great value buys among mid-size sedans for drivers who care how a car feels. This ranking covers every meaningful Mazda6 model year with real SkyActiv engine specs, fuel-economy figures, and realistic 2027 used-value ranges.
Direct Answer
The best overall Mazda6 is the 2018-2021 third-generation Signature Turbo, the most refined and powerful version, pairing the 2.5-liter turbocharged SkyActiv-G engine making up to 250 horsepower and 320 lb-ft of torque with a genuinely upscale Nappa-leather cabin that rivals entry luxury sedans for a fraction of the price.
The best value is the 2016-2017 third-generation Touring or Grand Touring (naturally aspirated), which delivers the same beautiful chassis and interior with the dependable 187-horsepower 2.5-liter engine; clean examples trade around $13,000 to $19,000. Below, the model years are ranked from best buy to least, with specs and pricing for each.
1. 2018-2021 Mazda6 Signature Turbo 🏆 BEST OVERALL
The final third-generation Signature Turbo cars are the best Mazda6 ever built. The 2.5-liter turbocharged SkyActiv-G makes 250 horsepower on 93-octane (227 on regular) and a muscular 320 lb-ft of torque from just 2,000 rpm, giving effortless, torque-rich acceleration that no naturally aspirated rival matches.
The 2018 redesign brought a dramatically upgraded interior, and the Signature trim layers genuine Nappa leather, Sen-wood trim, ultrasuede, and a 360-degree camera that shame far pricier badges. The chassis is composed and engaging, the ride refined. Expect $20,000-$28,000 for a clean Signature Turbo, and it is worth every dollar because nothing in the mid-size class offers this blend of pace, luxury, and driving feel for the money.
This is the Mazda6 to buy if budget allows.
2. 2016-2017 Mazda6 Grand Touring 💎 BEST VALUE
The mid-cycle third-generation cars are the value play, and the Grand Touring trim is the sweet spot. These cars use the naturally aspirated 2.5-liter SkyActiv-G making 184-187 horsepower, paired with class-leading fuel economy of up to 38 highway mpg and, on some trims, an available six-speed manual.
The 2016 refresh added G-Vectoring Control, improved sound deadening, and upgraded interior materials, giving near-luxury polish for sedan money. The Grand Touring adds leather, navigation, and a head-up display. Clean examples run $13,000-$19,000, a remarkable amount of refinement and driving joy for the price.
That combination of low cost, high reliability, and genuine class makes it the clear best value in the range.
3. 2014-2015 Mazda6 (third-gen launch)
The launch cars of the third generation reset the Mazda6 as a stylish, efficient, fun-to-drive sedan. The 2.5-liter SkyActiv-G makes 184 horsepower and delivers up to 40 highway mpg, and a slick six-speed manual was available — a rarity in the class. The Kodo styling still looks fresh, the chassis is wonderfully balanced, and reliability is strong.
Used prices sit around $10,000-$15,000, undercutting the refreshed cars. They rank just below the 2016-2017 value champions because they lack G-Vectoring Control and a few interior and tech upgrades, but mechanically and dynamically they are nearly identical. For a buyer who wants the third-gen experience at the lowest price, especially with the rare manual, the launch cars are an excellent target.
4. 2018-2019 Mazda6 Grand Touring (NA, refreshed)
The refreshed naturally aspirated cars from the 2018 redesign pair the upgraded interior and styling with the dependable 187-horsepower 2.5-liter engine. They deliver most of the Signature's premium feel and the same composed chassis without the turbo's cost, and they keep strong fuel economy.
Values run $16,000-$22,000. They rank here rather than higher because they cost more than the 2016-2017 value champions while offering a similar naturally aspirated driving experience, and they lack the Signature Turbo's punch and top-tier materials. Still, for a buyer who wants the newest, most refined non-turbo Mazda6 with the redesigned cabin, the refreshed Grand Touring is a polished, low-risk choice that feels a class above its price tag.
5. 2018 Mazda6 (redesign, first year)
The 2018 redesign is historically the most important third-generation update, debuting the turbocharged 2.5-liter engine in the Mazda6 and the dramatically upgraded interior. As the first year of the turbo, a 2018 Touring or Grand Touring Turbo offers the 227-250 horsepower engine and the refreshed cabin at a slightly lower price than later Signature cars.
Used prices run $17,000-$23,000. It ranks here because first-year-of-an-update cars carry a small risk of early quirks, and the loaded Signature delivers more luxury for not much more, but mechanically it is the same praised turbo package. For a buyer who wants the strong turbo engine and redesigned interior at the lowest entry point, the 2018 turbo cars are compelling.
6. 2009-2013 Mazda6 (second generation)
The second generation grew the Mazda6 to true mid-size proportions and offered a 2.5-liter four (170 horsepower) and a strong 3.7-liter V6 (272 horsepower) for buyers who wanted power. It retained the engaging handling that defined the nameplate, with the V6 cars genuinely quick.
Fuel economy on the four-cylinder reaches around 30 highway mpg. Clean cars trade for $5,000-$10,000, well under any third-gen car. They rank here because the interior and refinement lag the third generation and the V6 is thirsty, but they remain spacious, reliable, and fun.
A well-maintained 2.5 four is the economical pick; the V6 sport models are a budget enthusiast's choice for straight-line speed.
7. 2016-2017 Mazda6 Touring (NA, mid-trim)
The mid-trim Touring versions of the refreshed third generation round out the strong value options. They keep the excellent naturally aspirated 2.5-liter (184-187 hp) engine, the G-Vectoring chassis, and the upgraded cabin, but trim some luxury features compared with the Grand Touring to hit a lower price.
Values run $12,000-$17,000. They rank here rather than higher because for a small premium the Grand Touring adds leather, navigation, and a head-up display that meaningfully improve the car, making it the better value despite the Touring's lower sticker. Still, for a buyer who wants the third generation's driving feel and refinement at the lowest possible price with the refreshed updates, a clean Touring is a smart, dependable buy.
8. 2003-2008 Mazda6 (first generation)
The original first generation launched the nameplate and set the segment's handling benchmark, offering a 2.3-liter four (156-160 hp) and a sporty 3.0-liter V6 (220 hp), with sedan, hatchback, and wagon body styles — including the only Mazda6 wagon and hatch ever sold in the US.
The chassis is tossable and the V6 cars are genuinely fun. Values are very low at $3,000-$7,000. They rank near the bottom because of age, dated equipment, and significant rust risk in salt-belt regions, where corrosion can be structural. But for an enthusiast who wants the cheapest fun mid-size car, or specifically the rare hatch or wagon body style, a clean first-gen car is a bargain.
Buy strictly on rust-free condition and service history.
9. 2009-2013 Mazda6 V6 (second-gen, power pick)
The 3.7-liter V6 second-generation cars deserve a dedicated slot for buyers who want maximum power at a low price. The V6 makes 272 horsepower and 269 lb-ft, giving strong acceleration in a comfortable, roomy sedan, and it was available in loaded Grand Touring trim with leather and a sunroof.
Values run $6,000-$11,000. It ranks here because the V6's fuel thirst (around 24 highway mpg) and the older platform's refinement are clear downsides versus the third-gen turbo, but for the money it offers genuine speed. The main caution is to verify regular transmission and cooling-system service, since these are the key wear points.
For a budget buyer who prioritizes straight-line punch and space, the V6 is a lot of car for the price.
10. 2014-2015 Mazda6 i Sport (third-gen, base)
The base i Sport trim of the launch third generation rounds out the list as the most affordable way into the celebrated platform. With the 184-horsepower 2.5-liter engine, an available six-speed manual, and class-leading fuel economy, it is a no-frills but genuinely rewarding sedan.
Values bottom out at $9,000-$13,000. It ranks last because the base trim trims equipment to cloth seats and simpler infotainment, and a Touring or Grand Touring adds meaningful features for a modest premium. But for a buyer who wants the third generation's superb chassis and reliability at the lowest possible price, and especially one who wants the rare manual transmission, a clean i Sport is one of the best value driver's sedans on the used market.
What to Watch For When Buying
On third-generation Turbo cars, confirm disciplined full-synthetic oil-change history and listen for any rough idle or hesitation, since the direct-injected turbo engine rewards careful maintenance and can build carbon when neglected. Across all SkyActiv cars, check for the known infotainment lag or freezing and verify software updates.
First- and second-generation cars are notably prone to rust in salt-belt regions — inspect the rear wheel arches, rocker panels, subframe, and floor pans carefully, as corrosion can be structural and is the leading reason to walk away. On second-generation V6 cars, scrutinize the transmission and cooling system, including the water pump, which are the key wear items.
Across all years, check for uneven tire wear signaling alignment or suspension issues, confirm the manual transmission shifts cleanly without grinding on equipped cars, and verify smooth automatic shifts. Finally, ensure the power features, sunroof drains, and 360-degree camera on loaded cars work properly.
How to Choose
Decide first how much power and luxury you want. If you want the most refined, powerful Mazda6 with genuine near-luxury materials, the 2018-2021 Signature Turbo is the clear pick and worth its premium. If you want the same beautiful chassis and interior with a dependable naturally aspirated engine for thousands less, the 2016-2017 Grand Touring is the value sweet spot and the smart buy for most drivers.
Those who want the redesigned cabin without the turbo cost should look at a 2018-2019 naturally aspirated Grand Touring, while buyers on a strict budget who still want a fun sedan should consider a 2014-2015 third-gen car, ideally with the rare manual. Bargain hunters can drop to a clean second-gen four-cylinder for economy or a V6 for power.
In every case, buy rust-free, insist on documented maintenance, and prioritize a manual if you value engagement.
FAQ
Which Mazda6 year is the best? The 2018-2021 Signature Turbo is the best overall for its power and luxury, while the 2016-2017 Grand Touring is the best value; both showcase the third generation's class-leading handling and interior quality.
Is the Mazda6 turbo worth it? Yes if you value effortless acceleration; the 250-horsepower, 320-lb-ft turbo transforms the Mazda6 into a genuine sport sedan, though the 187-hp naturally aspirated engine is more than adequate for daily use and costs less to buy and fuel.
How reliable is the Mazda6? Very reliable across the SkyActiv third generation (2014-2021), with infotainment lag being a more common complaint than mechanical failure; older cars are dependable mechanically but require careful rust inspection in salt-belt regions.
Can you still get a manual Mazda6? A six-speed manual was available only on certain naturally aspirated third-generation trims (mainly 2014-2017 i Sport and Touring); it is rare and prized by enthusiasts, so expect to search for one and pay a small premium.
Bottom Line
The Mazda6 is the driver's choice among used mid-size sedans, and the rankings are clear. The 2018-2021 Signature Turbo is the best overall, combining 250 horsepower, 320 lb-ft of torque, and genuine Nappa-leather luxury that rivals entry-level luxury badges for far less money.
The 2016-2017 Grand Touring is the best value, delivering the same superb chassis and upscale interior with a dependable naturally aspirated engine for thousands less. Budget buyers can drop to a clean second-generation four-cylinder for economy or hunt the rare manual third-gen car for engagement.
Whatever year you target, buy rust-free, insist on documented maintenance — turbo oil discipline or V6 transmission service — and the Mazda6 will deliver more sedan per dollar than almost anything else on the used market.
