Pakistan's Swift is the sixth-generation car with a 1.2 four-cylinder and no electrification. Japan and Europe have moved on to the seventh generation with an entirely new three-cylinder, the Z12E, and a 12V mild hybrid - certified at 25.6 km/l on Japan's cycle against the 14.6 combined Pakistani owners report here. This is not the same car with a battery bolted on; it is a generation and an engine apart.
Each market tests to its own legal cycle, so these numbers describe the same engine measured three different ways. Read down a market, not across them. Figures are shown in km/l, with the market's own published unit beneath it wherever that unit differs.
| Variant | City | Highway | Combined | CO2 | Notes |
|---|---|---|---|---|---|
| 1.2 Z12E mild hybrid, CVT (7th generation) 82 PS · 108 Nm · CVT · Mild hybrid | 21.3 | 27 | 25.6 | 91 g/km | This is a generation ahead of the Swift Pakistan sells, not the same car with a battery added. The seventh-generation Swift introduced an entirely new engine - the Z12E, a three-cylinder replacing the four Pakistan uses - with a higher compression ratio and a 12V mild-hybrid system worth an extra 3 PS and 60 Nm when called on. Japan certifies it at 25.6 km/l combined against the 14.6 Pakistani owners report from the older car. Part of that is the test; most of it is a different engine. Certified on Japan's WLTC cycle, which is a laboratory test like Europe's but weighted differently, so its numbers are not directly comparable with WLTP figures. Source |

| 1.2 Z12E mild hybrid, CVT (7th generation) 82 PS · 108 Nm · CVT · Mild hybrid | — | — | 21.3 4.7 l/100km | — | The same seventh-generation car certified on Europe's cycle rather than Japan's, which is why the figure is lower for an identical vehicle: 4.7 l/100 km with the CVT, 4.4 with the manual. Read it against the Japanese row as a demonstration that a cycle, not a car, produces much of the difference between published economy figures. Certified on Europe's WLTP cycle, measured in a laboratory on a rolling road. Pakistani heat, traffic and fuel will not reproduce it. Source |
Europe and Australia certify in litres per 100 km; the km/l figure above it is our conversion, at 100 ÷ l per 100 km. Korea certifies in km/l, so those rows carry the published figure alone and no converted one.
What the international specification genuinely gains, and what it does not.
The Swift Pakistan sells and the Swift Japan sells are not the same generation of car.
Pak Suzuki assembles the sixth-generation Swift with a 1.2-litre four-cylinder and a CVT. Japan and Europe moved to the seventh generation in 2024, and that car brought an entirely new engine: the Z12E, a three-cylinder with a higher compression ratio, paired with a 12V mild-hybrid system that adds 3 PS and 60 Nm when the car asks for it.
Japan certifies the new Swift at 25.6 km/l combined on the WLTC cycle - 21.3 in the urban phase and 27.0 extra-urban - with 91 g/km of CO2. Europe certifies the same car at 4.7 l/100 km with the CVT and 4.4 with the manual, which is 21.3 and 22.7 km/l.
Pakistani owners of the car sold here report about 13 km/l in the city and 17 on the highway.
It is worth being precise about why those differ so much. Part is the test: Japan's WLTC and Europe's WLTP are both laboratory cycles and neither reproduces Pakistani conditions. But most of it is simply that these are different cars with different engines, a generation apart.
The seventh-generation Swift uses the Z12E: a 1,197 cc three-cylinder petrol engine with a raised compression ratio, rated at 82 PS and 108 Nm, driving through a CVT or a five-speed manual. The 12V mild-hybrid system contributes up to 3 PS and 60 Nm of assist when accelerating, and allows smoother stop-start. A four-wheel-drive AllGrip version is offered in some markets.
Pakistan's Swift uses the previous generation's 1.2-litre four-cylinder with a CVT or manual, without any electrification.
The move from four cylinders to three is the main efficiency change - fewer cylinders means less friction and less pumping loss, which is the same reasoning behind the three-cylinder engines in the Stonic and the new Yaris.
Japan certifies the seventh-generation Swift at 25.6 km/l combined on the WLTC cycle, split 21.3 km/l urban and 27.0 extra-urban.
Europe certifies the identical car at 4.7 l/100 km with the CVT - 21.3 km/l - and 4.4 with the manual, 22.7 km/l.
The same vehicle reading 25.6 in Japan and 21.3 in Europe is worth noticing on its own. Nothing about the car changed; the cycle did. It is the clearest illustration in this section of why figures from different markets must never be compared directly, which is why every row on these pages names the cycle that produced it.
Pakistani owners of the sixth-generation Swift sold here report about 13 km/l in the city and 17 on the highway, roughly 14.6 combined. That gap against the Japanese figure is partly the test and mostly a different engine - do not read it as what better driving could achieve in the local car.
The seventh-generation Swift carries Suzuki Safety Support in Japan and Europe: dual-sensor autonomous emergency braking with pedestrian detection, lane-departure warning, adaptive cruise control and blind-spot monitoring on higher trims.
Euro NCAP tested the seventh-generation Swift in 2024 and awarded three stars, with the published criticism centring on the assistance systems rather than the structure - which is a useful reminder that modern NCAP scores are driven heavily by electronics.
Pakistan's Swift is offered with two airbags on lower trims and no driver assistance of any kind, and has never been independently crash-tested because Pakistan has no programme.
No. Pak Suzuki continues to assemble the previous, sixth-generation Swift with a 1.2-litre four-cylinder. The seventh-generation car with the Z12E three-cylinder and mild hybrid launched in Japan and Europe in 2024 and has not been announced for Pakistan.
Japan certifies it at 25.6 km/l combined on the WLTC cycle, 21.3 urban and 27.0 extra-urban. Europe certifies the same car at 4.7 l/100 km with the CVT, which is 21.3 km/l. Both are laboratory figures.
Because they are different tests. Japan's WLTC and Europe's WLTP weight their phases differently, so an identical vehicle reads 25.6 km/l on one and 21.3 on the other. This is exactly why figures from different markets should never be compared directly.
No. The 25.6 km/l figure belongs to a different generation of the car with a different engine - a three-cylinder Z12E with mild-hybrid assist rather than the four-cylinder Pakistan uses. Pakistani owners of the car sold here report about 13 km/l in the city and 17 on the highway.
No. It is a 12V system that assists the engine with up to 3 PS and smooths stop-start. It cannot drive the car on electricity at all. A Toyota or Honda full hybrid has a far larger motor and battery and can move the car without the engine running.
