Comprehensive Review of the 2016 Mazda6 Grand Touring: A Decade of SkyActiv Excellence

The 2016 Mazda6 Grand Touring is a flagship midsize sedan celebrated for its "Jinba Ittai" (horse and rider as one) driving philosophy, striking KODO design, and premium interior. In 2026, it remains a highly sought-after used vehicle, offering a sophisticated balance of fuel efficiency, reliability, and engaging performance that rivals many contemporary entry-level luxury cars.

The Evolution of the 2016 Refresh

While the third-generation Mazda6 debuted for the 2014 model year, the 2016 version represented a significant "mid-cycle refresh." This specific year is often cited by enthusiasts as the sweet spot for the GJ generation because it addressed the two primary criticisms of the earlier models: the aging infotainment system and the somewhat utilitarian interior materials.

The exterior received subtle but impactful updates. The Grand Touring trim, in particular, benefited from a new signature wing grille with optional LED lighting accents and a more aggressive front fascia. Mazda also introduced LED headlights and taillights for this trim, which have aged remarkably well compared to the halogen or HID setups of competitors from the same era. The 19-inch aluminum alloy wheels with a high-luster "dark silver" finish remain a standout feature, giving the car a planted, athletic stance that many 2026 sedans struggle to replicate.

Inside, the transformation was even more dramatic. Mazda replaced the integrated dashboard screen with a "floating" 7-inch Mazda Connect display. They also redesigned the center console, removing the traditional handbrake in favor of an electronic parking brake (EPB), which freed up space for a more ergonomic Commander Switch control knob. For the Grand Touring trim, the use of soft-touch materials, contrast stitching, and the optional Parchment leather interior pushed the car into a near-luxury category, often drawing comparisons to Audi or BMW rather than Honda or Toyota.

Engineering and Performance: The SkyActiv-G 2.5L

At the heart of the 2016 Mazda6 Grand Touring is the 2.5-liter SkyActiv-G four-cylinder engine. In an era where many manufacturers were moving toward small-displacement turbocharged engines, Mazda doubled down on high-compression, naturally aspirated technology.

Technical Specifications

The engine produces 184 horsepower at 5,700 rpm and 185 lb-ft of torque at 3,250 rpm. While these numbers might seem modest by 2026 standards, the delivery is what sets it apart. The SkyActiv-G engine utilizes a 13:1 compression ratio and a unique 4-2-1 exhaust header system to maximize thermal efficiency. This results in a linear power delivery that feels more responsive in city driving than many turbocharged rivals that suffer from "turbo lag."

The Six-Speed Automatic Transmission

Unlike the Continuously Variable Transmissions (CVTs) found in the 2016 Nissan Altima or Honda Accord, Mazda employed a six-speed SkyActiv-Drive automatic transmission. This gearbox was designed to combine the best attributes of a traditional torque-converter automatic, a dual-clutch transmission, and a CVT. It features a full-range direct-drive lockup for the majority of its operating range, providing a mechanical "connected" feel and rapid downshifts when the Sport Mode toggle is engaged.

Fuel Economy and Real-World Efficiency

According to the U.S. Department of Energy, the 2016 Mazda6 Grand Touring achieved an EPA-estimated 26 city / 37 highway MPG. Models equipped with the i-ELOOP (Intelligent Energy Loop) regenerative braking system—part of the Technology Package—could see a slight bump to 28 city / 40 highway MPG. In 2026, these figures remain competitive, making the Mazda6 a viable commuter car for those looking to avoid the high entry costs of modern hybrids.

Grand Touring Features and Technology

The Grand Touring was the pinnacle of the 2016 lineup, coming standard with features that were often optional or unavailable on its peers. Understanding these features is critical for buyers in 2026 to ensure the specific used unit they are inspecting is fully functional.

• Active Driving Display: A pop-up head-up display (HUD) that shows vehicle speed, cruise control settings, and navigation instructions. While the plastic screen can be prone to motor failure over a decade of use, it remains a futuristic touch for a 2016 model.
• Bose Centerpoint Surround Sound: An 11-speaker system specifically tuned for the Mazda6 cabin. It provides excellent clarity, though some users in 2026 may find the lack of native Apple CarPlay or Android Auto a drawback (though many units were retrofitted with these by dealers later).
• Adaptive Front-lighting System (AFS): The LED headlights actually turn with the steering wheel to illuminate corners, a safety feature typically reserved for European luxury brands in 2016.
• Dual-Zone Climate Control: Standard on the Grand Touring, allowing separate temperature settings for the driver and front passenger.

Safety and Driver Assistance (i-ACTIVSENSE)

In 2016, Mazda's i-ACTIVSENSE suite was one of the most comprehensive safety packages in the midsize segment. For the Grand Touring trim, many of these features were standard or part of the "GT Technology Package."

The National Highway Traffic Safety Administration (NHTSA) gave the 2016 Mazda6 a 5-star overall safety rating. Similarly, the Insurance Institute for Highway Safety (IIHS) designated it a Top Safety Pick+ when equipped with the optional front crash prevention system.

Key Safety Systems:

1. Smart City Brake Support (SCBS): A laser-based system that can automatically apply the brakes at low speeds (between 2 and 18 mph) to prevent or mitigate front-end collisions.
2. Blind Spot Monitoring (BSM) & Rear Cross Traffic Alert (RCTA): Standard on the GT, these use radar to detect vehicles in adjacent lanes or approaching from the side while reversing.
3. Mazda Radar Cruise Control (MRCC): Unlike basic cruise control, MRCC uses a millimetric wave radar to maintain a set distance from the vehicle ahead.
4. Lane Departure Warning System (LDWS): Provides an audible or haptic warning if the vehicle begins to drift out of its lane without a turn signal.

Long-Term Reliability and 2026 Maintenance Outlook

As we look at the 2016 Mazda6 Grand Touring from the perspective of 2026, the car is now a decade old. For most owners, this means the odometer likely reads between 100,000 and 150,000 miles. Fortunately, the GJ generation has proven to be one of Mazda's most reliable platforms.

Common Issues to Inspect

While the engine and transmission are robust, there are specific "age-related" issues that prospective buyers should verify:

• Hydraulic Belt Tensioner: One of the most common mechanical failures is a leaking belt tensioner. If you see oil residue on the passenger side of the engine block near the serpentine belt, the tensioner likely needs replacement.
• Infotainment "Ghost Touching": Some 2016 models suffered from delamination of the touchscreen, causing the system to register phantom inputs. This often requires a replacement of the screen assembly or the Connectivity Master Unit (CMU).
• Rear Brake Calipers: The electronic parking brake system can sometimes cause the rear brake pads to wear unevenly or the calipers to stick. Regular servicing of the slide pins is essential.
• Suspension Bushings: Given the car's sporty tuning and 19-inch wheels, the front lower control arm bushings often show significant wear by the 100,000-mile mark, leading to clunking sounds over bumps.

Maintenance Schedule for High-Mileage Units

In 2026, maintenance should focus on longevity. Mazda uses a "Lifetime" transmission fluid, but many independent mechanics recommend a drain-and-fill of the SkyActiv-Drive fluid every 60,000 to 75,000 miles to preserve shift quality. Spark plugs (iridium) should be replaced every 75,000 miles, and the coolant should be flushed using Mazda FL22-rated fluid to protect the aluminum engine components.

Comparing the 2016 Mazda6 to Its Rivals

To understand the value proposition of the 2016 Mazda6 Grand Touring, it is helpful to compare it against the 2016 Honda Accord and the 2016 Toyota Camry, which were its primary competitors.

vs. 2016 Honda Accord (EX-L/Touring)

The Accord offered a V6 option which provided significantly more power than the Mazda's inline-four. However, the Mazda6 was widely considered the better-handling car, with more communicative steering and a more premium-feeling interior. The Accord's dual-screen infotainment system was often criticized for being confusing, whereas the Mazda Connect system was praised for its BMW-like rotary controller.

vs. 2016 Toyota Camry (XLE)

The Camry of this era focused heavily on comfort and isolation. While the Camry has an edge in rear-seat legroom and trunk space, the Mazda6 wins on engagement and aesthetics. In 2026, the Mazda6 often holds a "niche" appeal for buyers who want a car that doesn't feel like a generic appliance.

Is the 2016 Mazda6 Grand Touring Right for You in 2026?

Purchasing a decade-old vehicle requires a pragmatic approach. The 2016 Mazda6 Grand Touring is best suited for individuals who value the driving experience and aesthetic appeal over raw interior volume or the latest 2026-era autonomous driving tech.

Pros:

• Timeless Aesthetics: The KODO design language has not aged significantly, and the car still looks modern in 2026 traffic.
• Driving Dynamics: The steering is weighted perfectly, and the chassis is responsive without being overly harsh.
• Simple Mechanicals: No turbocharger and a traditional automatic transmission mean fewer complex components to fail as the car ages.

Cons:

• Road Noise: Despite the 2016 refresh including more sound insulation, the Mazda6 is still louder on the highway than a Camry or an Accord, especially with the 19-inch wheels.
• Infotainment Speed: The 2016 processor is slow by modern standards, and the navigation maps may be outdated unless the system was updated.
• Small Trunk: At 14.8 cubic feet, the trunk is smaller than many of its rivals.

FAQ

Does the 2016 Mazda6 Grand Touring have Apple CarPlay?

It did not come with Apple CarPlay or Android Auto from the factory. However, Mazda released a hardware and software retrofit kit (consisting of a new USB hub and updated firmware) that can be installed on 2016 models. If you are buying one in 2026, check if this "Apple CarPlay/Android Auto Retrofit" has already been performed.

How many miles can a 2016 Mazda6 last?

With proper maintenance, the 2.5L SkyActiv engine is known to exceed 200,000 to 250,000 miles. The key is timely oil changes (using 0W-20 synthetic) and ensuring the cooling system remains in good condition.

What is the difference between the 2015 and 2016 Mazda6?

The 2016 model received a major interior overhaul. While the 2015 had a dashboard with an integrated, small screen and a manual handbrake, the 2016 introduced the "floating" tablet screen, a new center console with an electronic parking brake, and improved interior materials. The 2016 also added LED lighting options and a revised front grille.

Is the i-ELOOP system worth it?

i-ELOOP is a capacitor-based regenerative braking system that powers the car's electronics to reduce the load on the alternator. While it improves fuel economy by about 1-2 MPG, it requires a special, more expensive Q85 battery. In 2026, if the system fails, the cost of repair may outweigh the fuel savings for some owners.

Are the 19-inch wheels prone to damage?

The 19-inch wheels on the Grand Touring look excellent but have a lower profile tire (225/45R19). This makes them more susceptible to pothole damage and results in a slightly firmer ride. Some owners choose to "downsize" to the 17-inch wheels from the Sport or Touring trims for improved ride comfort and cheaper tire replacement costs.

Final Recommendation

For those in the market for a used sedan in 2026, the 2016 Mazda6 Grand Touring represents an exceptional value. It offers a level of style and driver engagement that few other cars in its price bracket can match. To ensure a successful purchase, prioritize vehicles with a documented service history, specifically looking for evidence of spark plug changes and belt tensioner inspections. If you can find a well-maintained "Soul Red" or "Snowflake White" unit that has already had the CarPlay retrofit, you will have a vehicle that feels much younger than its ten years would suggest.
