In the US market, the Mazda 3 was offered primarily with gasoline Skyactiv-G engines. Diesel versions were not officially available, and all-wheel drive (i-Activ AWD) was not offered on this generation. Exterior design, interior, trim levels, and common issues are covered in separate articles in this series.
Engines and Transmissions
The powertrain lineup for the third-generation Mazda 3 is built around Skyactiv technology. For the North American market, it featured gasoline Skyactiv-G engines with direct injection and high compression ratios. The most common options were the 2.0L and later the 2.5L engines. No diesel engines were sold officially in the US.
All engines were paired with six-speed transmissions: Skyactiv-MT manual or Skyactiv-Drive automatic (torque converter). All-wheel drive was not available.
| Fuel Type | Displacement, L | Engine Code | Power, hp | Torque, lb-ft | Transmission | Drivetrain | Availability Period (approx.) | Notes for US Market |
| Gasoline | 2.0 | Skyactiv-G (PE-VPS) | 155 | 150 | 6-MT / 6-AT | Front | 2014–2018 | Common base engine |
| Gasoline | 2.0 | Skyactiv-G (PE-VPS) | 155 | 150 | 6-MT / 6-AT | Front | 2014–2018 | Widely available |
| Gasoline | 2.5 | Skyactiv-G | 184–186 | 185 | 6-AT | Front | 2014–2019 | Most popular performance-oriented option |
| Gasoline | 2.5 | Skyactiv-G | 184–186 | 185 | 6-AT | Front | 2016–2019 (facelift) | Standard in higher trims post-facelift |
Dimensions and Weight
The overall dimensions of the third-generation Mazda 3 remained largely consistent throughout production. Minor differences existed between hatchback and sedan variants, as well as pre- and post-facelift models (mainly in height and ground clearance due to suspension tuning). Drivetrain had minimal impact on weight (differences up to 60–100 lbs).
| Parameter | Hatchback (BM/BN) | Sedan (BM/BN) | Notes |
| Length, in | 175.6–180.3 | 180.3–183.5 | Sedan is about 4–5 inches longer |
| Width, in | 70.7 | 70.7 | Without mirrors |
| Height, in | 56.5–57.3 | 57.3 | Varies by trim and wheels |
| Wheelbase, in | 106.3 | 106.3 | Same for all |
| Ground Clearance, in | 5.5–6.1 | 5.5–6.1 | Manufacturer spec; real-world often around 5.5–6.0 in |
| Curb Weight, lbs | 2,800–3,100 | 2,900–3,050 | Depending on engine and equipment |
| Gross Weight, lbs | 3,900–4,200 | 4,000–4,200 | Maximum permitted |
| Cargo Volume, cu ft | 20.1–47.1 | 12.4 | Hatchback with folded seats |
Yearly Updates and Facelift
Production began in 2014 with the pre-facelift BM body. By 2015, the lineup stabilized with the 2.0L and 2.5L gasoline engines as the main options.
The facelift arrived mid-2016 (for the 2017 model year). Changes included updated headlights, bumpers, taillights, revised interior (new instrument cluster, improved materials), addition of G-Vectoring Control for better handling, and enhanced sound insulation. The 2.5L engine became more prominent in higher trims. Minor updates in 2018–2019 focused on infotainment and available features.
On the US used market, facelifted models (2017–2019) are more common and generally preferred due to refinements in suspension, handling, and electronics.
Ownership Notes and Technical Highlights
Skyactiv-G engines (2.0L and 2.5L) are highly reliable with proper maintenance (oil changes recommended every 5,000–7,500 miles). High-mileage examples (150,000–200,000+ miles) without major repairs are common when using quality premium unleaded fuel and oil. No diesel options were offered in the US, so maintenance is straightforward.
The most popular choices on the used market are the 2.5L Skyactiv-G (184–186 hp) with 6-speed automatic (great balance of performance and comfort) and the 2.0L version for better fuel economy. Real-world fuel economy (based on owner reports): 2.5L around 26–30 mpg combined, 2.0L around 28–33 mpg combined (higher on highway, add 1–3 mpg in winter).
The Skyactiv-Drive automatic is durable with fluid changes every 40,000 miles; the manual is virtually bulletproof. Parts are widely available with plenty of aftermarket options, and originals are reasonably priced. The car is easy to repair, though paint and body panels are thin and can rust in hidden areas if chipped.
Summary and Best Pick for the US Market
On the US used market, the sweet spot is a facelifted Mazda 3 (2017–2019) with the 2.5L Skyactiv-G engine and automatic transmission. This combo delivers strong performance, reasonable fuel economy, affordable maintenance, and excellent resale value. The 2.0L version suits those prioritizing maximum efficiency and lower running costs.
Approximate market price range for well-maintained examples: $9,000–$16,000 depending on mileage, condition, and trim (check current local listings for precise values).
When shopping, always verify service history, transmission condition, no overheating issues, and no signs of major accident damage or frame repairs.
