All versions below use the name exactly as in the data. Cylinders and layout are taken from the same rows.

4 generation (from 2018-11-01, no end date in the data) is a Sedan. Ground clearance on measured versions is 135 mm. The fuel tank is 51 l. This is the only generation here with AWD (2.5L SKYACTIV-G AWD AT, 2.5 AT).

3 generation, restyling (2016-08-01 to 2019-05-31) is a Sedan. Ground clearance is 155 mm on the listed versions — 20 mm more than the current generation’s 135 mm. Tank 51 l.

3 generation (2013-06-01 to 2016-07-31) is a Sedan. Ground clearance is 155 mm or 160 mm depending on version. Tank 51 l. This generation still has the 2.5 AT / 2.5 MT at 184 hp without turbo in the data (`nadduv_en`: No).

Top speed: highest measured is 1 generation 2.3 MT / 2.3 AT at 160 hp — 220 km/h. Next cluster: 2 generation 2.2 MT (185 hp) 214 km/h; 3 generation, restyling 2.2 MT 213 km/h; 3 generation 2.0 AT (150 hp) and 2.0 MT (165 hp) 210 km/h. 4 generation peaks at 209 km/h on 2.0 AT (153 hp) and 2.5L SKYACTIV-G MT. 4 generation 1.8 AT / 1.8 MT are 199 km/h. 1 generation 1.4 MT is 169 km/h. Several 2.5 AT / 2.5 MT and 2.5L SKYACTIV-G rows: top speed not measured.

Fuel (mixed l/100 km) and CO2: lowest mixed figure in the whole file is 3 generation, restyling 1.5 MT diesel at 3.8 l/100 km and 99 g/km CO2. 4 generation 1.8 MT is 4.1 l/100 km and 106 g/km. 4 generation 1.8 AT is 4.6 l/100 km and 120 g/km — the automatic uses 0.5 l/100 km more mixed and 14 g/km more CO2. 4 generation 2.0 MT (122 hp) mixed 5.1, CO2 115; 2.0 AT (122 hp) mixed 5.5, CO2 125. 4 generation 2.0 AT (153 hp) mixed 7.6 — 2.1 l/100 km more than the 122 hp automatic, for 31 hp extra. 4 generation 2.5L SKYACTIV-G AT mixed 7.6; 2.5L SKYACTIV-G MT mixed 5.8 (1.8 l/100 km less than the automatic of the same 140 hp). 2.5L SKYACTIV-G city 10.2 / highway 8.7, mixed not measured. 2.5 AT (227 hp, AWD): city, highway, mixed all not measured. Older petrol 2.0 AT in 2 generation mixed 7.6 with city 10.6. 1 generation 2.3 AT (160 hp) mixed 9.0. Eco class where listed: Euro 5 or Euro 6; many rows not measured.

Dimensions and weight

Tank: 51 l from 3 generation onward; 55 l in 1 generation and 2 generation (including restylings) — 4 l more.

Ground clearance: 4 generation measured rows 135 mm. 3 generation, restyling 155 mm. 3 generation 155 mm or 160 mm (1.6 AT / 1.6 MT). 2 generation family 155 mm. 1 generation, restyling 160 mm or 169 mm. 1 generation 160 mm, 140 mm (1.4 MT 80 hp, 1.6 MT 105 hp one row), or 135 mm (1.6 AT). Choosing 4 generation versus 3 generation, restyling means 20 mm less clearance on the measured cars.

Which version to choose

If you are buying new or current 4 generation. The catalogue does not contain prices, so “what the extra money buys” can only mean what the extra specification buys in hardware.

• Daily petrol automatic, FWD: 2.0 AT at 153 hp is the one to prefer over 2.0 AT at 122 hp if acceleration matters: 9.0 s vs 10.8 s, 209 vs 202 km/h, 203 vs 213 Nm. You pay in fuel: mixed 7.6 vs 5.5 l/100 km. Weight is 1354 kg vs 1300 kg. Both are 1998 cm³, Gasoline, Direct injection (direct), 6-speed Automatic, FWD, Euro 6 on the 153 hp row (122 hp also Euro 6).
• Same 2.0, want a manual: 2.0 MT at 122 hp is 0.4 s quicker than 2.0 AT at 122 hp (10.4 vs 10.8), 25 kg lighter, mixed 5.1 vs 5.5, CO2 115 vs 125. There is no 2.0 MT at 153 hp in 4 generation.
• Strongest 2.0 automatic in 4 generation: 2.0L SKYACTIV-G at 165 hp, 218 Nm, 0–100 8.5 s, top 208 km/h. Mixed consumption not measured. Gross 1454 kg (kerb not measured). Boost not measured.
• Least fuel in 4 generation: 1.8 MT Diesel Turbo, 116 hp, 270 Nm from 1600–2600 rpm, mixed 4.1, city 4.6, highway 3.8, CO2 106, Euro 6. 1.8 AT is the automatic twin: 12.1 s vs 10.3 s, mixed 4.6. Both top out at 199 km/h. Torque is 117 Nm above 2.0 AT at 153 hp (203 Nm), even though peak power is 37 hp lower.
• Entry petrol automatic: 1.5 AT, 120 hp, 153 Nm, 1496 cm³, 0–100 12.3 s, top 200 km/h, mixed 6.0, Euro 5 (the only Euro 5 in 4 generation among these rows). It is 2 hp below 2.0 MT 122 hp but 60 Nm down and 1.9 s slower, with mixed 0.9 l/100 km higher than that manual 2.0.
• Peak power in 4 generation: 2.5L SKYACTIV-G (227 hp, 422 Nm, Turbo, FWD, from 2019-03-01) and 2.5 AT (227 hp, 422 Nm, AWD, from 2025-01-01). 0–100, top speed, mixed, CO2, eco class: not measured on both. 2.5 AT has kerb 1534 kg; 2.5L SKYACTIV-G kerb not measured. The AWD 2.5 AT is the late high-output all-wheel row; 2.5L SKYACTIV-G AWD AT is a different tune: 191 hp, 252 Nm, mixed 7.8, 0–100 not measured, from 2022-01-01.
• 2.5 without the 227 hp tune: 2.5L SKYACTIV-G AT 140 hp, 238 Nm, 0–100 9.3 s, top 203 km/h, mixed 7.6. 2.5L SKYACTIV-G MT same 140 hp, 9.5 s, top 209 km/h, mixed 5.8. The manual 2.5 at 140 hp uses 1.8 l/100 km less mixed than the automatic and matches 2.0 AT 153 hp on top speed.

If you are comparing 4 generation with 3 generation. Clearance falls 20 mm (155 → 135). Tank stays 51 l. The old 2.5 AT at 184 hp (No turbo) did 0–100 in 7.9 s in 3 generation — faster than any measured 4 generation petrol except none beat 7.9 here; 4 generation 2.0L SKYACTIV-G is 8.5 s. 3 generation 2.0 MT at 165 hp is 8.2 s and 7.8 kg/hp vs 4 generation 2.0 AT 153 hp at 9.0 s and 8.8 kg/hp. Diesel: 3 generation, restyling 2.2 MT 150 hp / 380 Nm, 8.0 s, mixed 3.9, CO2 104 vs 4 generation 1.8 MT 116 hp / 270 Nm, 10.3 s, mixed 4.1. The restyle diesel 1.5 MT at 105 hp still has the catalogue’s best mixed 3.8 and CO2 99.

If you are looking at 2 generation. You get a 55 l tank and 155 mm clearance. The unique hardware is the 6-cylinder V-shaped 2.5 MT / 2.5 AT at 167 hp — no later generation lists that cylinder layout. 2.5 AT 0–100 is 8.8 s (restyling) or 8.7 s (pre-restyle); top speed not measured on those automatics. The 2.2 MT diesel at 185 hp / 400 Nm is 8.2 s and 214 km/h, kerb 1465 kg. Petrol 2.0 AT mixed 7.6 with city 10.6 — thirstier in town than 4 generation 2.0 AT 122 hp city 7.0.

If you are looking at 1 generation. 2.3 MT / 2.3 AT at 160 hp are the quickest and fastest Mazda 3 rows in this file: 7.6 s and 220 km/h. Mixed 8.4 (MT) and 9.0 (AT). 1.4 MT is the weakest: 80–84 hp, 14.3 s, 169 km/h, about 14 kg/hp. 1 generation, restyling 2.0 AT lists 169 mm clearance — the highest figure in the data — versus 135 mm on current 4 generation. Tank 55 l vs 51 l.

Problems and reliability, as far as these numbers go. This dataset does not record failures, service campaigns, or durability. What it does record as gaps: several high-output 4 generation 2.5 rows leave 0–100, top speed, weight, CO2, and eco class not measured, so they cannot be ranked on those axes against 2.0 AT 153 hp. Duplicate names (2.0 AT, 1.5 MT, 2.0 MT, 1.6 MT, 2.5 AT) are different engines or different masses; matching on the badge alone is the reliability risk for the buyer, not a claim about breakdowns.

Practical shortlist from the arithmetic. 4 generation 2.0 AT (153 hp) for a current petrol automatic with measured pace. 4 generation 2.0 MT (122 hp) for the lightest current 2.0 and the lowest petrol mixed among current 2.0s with a figure. 4 generation 1.8 MT for economy and torque. 4 generation 2.5L SKYACTIV-G or 2.5 AT (227 hp) only if 227 hp / 422 Nm is the requirement and missing 0–100 is acceptable. 3 generation, restyling 1.5 MT diesel or 2.2 MT if a used car’s job is minimum mixed fuel. 3 generation 2.0 MT (165 hp) or 2.5 AT (184 hp) if a used petrol should undercut current 0–100 times. 2 generation 2.5 AT / 2.5 MT if the 6-cylinder V-shaped layout is the reason to buy. 1 generation 2.3 MT (160 hp) if the file’s best 0–100 and top speed are the reason — knowing mixed fuel is 8.4 l/100 km and the car is a 2003–2006 Sedan.
