In 2013, this was the first generation of the new „Kodo“ design Mazda 6, and it was a massive step up from the previous model.
Here is your outline of benefits:
Part 1: The Core „Skyactiv“ Benefits (The Mechanical Genius)
This isn’t just an engine; it’s a full-vehicle philosophy. The benefits are:
Exceptional Fuel Economy (Without a Hybrid): The 2.0-liter Skyactiv-G petrol engine uses a high 13:1 compression ratio. In the real world, this returns 40–45 mpg (UK) / 34–38 mpg (US) on the highway. It rivals diesel cars of the era but runs on regular unleaded.
Responsive, Linear Power Delivery: Unlike turbocharged rivals (like the VW Passat), the naturally aspirated Skyactiv engine delivers power smoothly and predictably. It pulls cleanly from low revs, making city driving relaxed and overtaking predictable.
Tactile, Weighty Steering: The Skyactiv chassis uses electric power steering that is calibrated for feel, not numbness. It offers superb feedback, making the car feel lighter and more agile than its 1.4-ton weight suggests.
Rigid, Lightweight Body: Mazda used high-tensile steel to make the chassis 30% stiffer but lighter than the previous generation. This directly translates to sharper turn-in, less body roll, and a quieter cabin at motorway speeds.
Intelligent „i-Stop“ System: The start-stop system is unusually quick and smooth. It restarts the engine via combustion (rather than just the starter motor), making it almost imperceptible in traffic.
Part 2: The „FULL Extras“ Benefits (The Premium Spec)
In 2013, „FULL Extras“ on a Mazda 6 usually means it is the Sport / GT-Model with the Technology Pack and Safety Pack added. Here is what you gain over a base model:
Adaptive LED Headlights (ALH): Instead of just bending the beam, these LEDs automatically shut off specific segments of the high-beam to avoid dazzling oncoming cars, while keeping the rest of the road fully lit. This is a huge safety benefit for night driving.
Radar Cruise Control (MRCC): Mazda’s early adaptive cruise control automatically maintains a safe distance from the car ahead, adjusting your speed on the motorway without you touching the pedals.
Smart City Brake Support (SCBS): An automatic emergency braking system that works at low speeds (under 19 mph) to prevent or mitigate city rear-end collisions.
Lane Departure Warning (LDW): Alerts you if you drift out of your lane without indicating—a valuable aid on long, monotonous journeys.
Bose 11-Speaker Sound System: A massive upgrade over the stock stereo. The bass is punchy, and the soundstage is wide, making the quiet cabin feel like a concert hall.
Full Leather Heated Seats: The front seats are not just leather; they are heated with 3 temperature settings. The driver’s seat also features 8-way electric adjustment with 2-position memory.
19-inch Alloy Wheels: While the base car gets 17-inch wheels, the „FULL Extras“ version gets stunning 19-inch gunmetal or silver alloys. They fill the arches perfectly, giving the car an aggressive, premium stance that still looks modern today.
Satellite Navigation with TMC: Integrated TomTom-based navigation displayed on the 5.8-inch screen, including real-time traffic management (TMC) to reroute you around jams.
Part 3: The „Hidden“ Benefits of buying this specific spec today
Depreciation Floor: This is the „cult classic“ Mazda. The 2013 Skyactiv is widely considered more reliable and simpler than the later diesel versions. A well-maintained „FULL Extras“ petrol model has already taken its biggest depreciation hit and will hold its value well.
Analog Charm: This was the last era before massive touchscreens dominated the dash. You get physical buttons for the climate control and a rotary dial for the infotainment—meaning you can adjust everything without taking your eyes off the road.
No AdBlue / DPF Hassle: Because this is the petrol Skyactiv (not the diesel), you avoid the expensive diesel particulate filter (DPF) and AdBlue issues that plagued many 2013 executive saloons.
