Suzuki Kei

Specs: every 0.7 MT and 0.7 AT

Engine location is Front, transverse on every turbo version; it is not measured on both 54 hp versions. Injection is Distributed injection (multi-point) on all ten.

Weight per horsepower (the real ranking)

Kerb mass ÷ power, from the table:

• 0.7 MT 64 hp FWD: 710 / 64 ≈ 11.1 kg/hp (lightest per hp)
• 0.7 AT 64 hp FWD: 720 / 64 ≈ 11.3 kg/hp
• 0.7 MT 60 hp FWD: 700 / 60 ≈ 11.7 kg/hp (lightest car overall, 700 kg)
• 0.7 MT 64 hp AWD: 760 / 64 ≈ 11.9 kg/hp
• 0.7 AT 60 hp FWD and 0.7 AT 64 hp AWD: 720 / 60 = 12.0 and 770 / 64 ≈ 12.0 kg/hp
• 0.7 MT 60 hp AWD: 760 / 60 ≈ 12.7 kg/hp
• 0.7 AT 60 hp AWD: 770 / 60 ≈ 12.8 kg/hp
• 0.7 MT 54 hp: 740 / 54 ≈ 13.7 kg/hp
• 0.7 AT 54 hp: 770 / 54 ≈ 14.3 kg/hp (heaviest per hp)

The 54 hp 0.7 AT is 770 kg with the weakest engine: same kerb as the 64 hp 0.7 AT AWD, but 10 hp and 43 Nm less. The 60 hp 0.7 MT FWD is the lightest Kei in the data (700 kg), 70 kg under that 770 kg pair.

Gross weight is 960 kg on both 54 hp versions only. Payload there is 960 − 740 = 220 kg on the 0.7 MT 54 hp and 960 − 770 = 190 kg on the 0.7 AT 54 hp. Gross weight is not measured on the eight turbo versions.

What AWD buys (and what it costs in kilograms)

AWD exists only on turbo cars. Clearance is 185 mm on every AWD row and 175 mm on every FWD row (+10 mm).

Mass penalty versus the matching FWD gearbox:

• 0.7 MT 60 hp: AWD 760 vs FWD 700 → +60 kg
• 0.7 AT 60 hp: 770 vs 720 → +50 kg
• 0.7 MT 64 hp: 760 vs 710 → +50 kg
• 0.7 AT 64 hp: 770 vs 720 → +50 kg

AWD does not change tank size (30 L on all ten), brakes (Disc front, Drum rear on all ten), or front suspension (Independent, spring on all ten). Rear suspension is Independent, spring only on the two 54 hp cars; the eight turbo cars use Semi-independent, springorts hélicoïdaux, sem as labelled in the data.

If you need the extra 10 mm and AWD, the efficient AWD pick on paper is 0.7 MT 64 hp AWD: same 760 kg as 0.7 MT 60 hp AWD, but +4 hp and +23 Nm. The 0.7 AT AWD cars are both 770 kg; the 64 hp one adds a 4-speed Automatic versus the 60 hp 3-speed Automatic.

Manual vs Automatic

All 0.7 MT versions are Manual 5. Automatics split:

• 3 speeds: both 54 hp 0.7 AT and both 60 hp 0.7 AT
• 4 speeds: both 64 hp 0.7 AT

Automatic mass versus the same engine and drive:

• 54 hp FWD: AT 770 vs MT 740 → +30 kg
• 60 hp FWD: 720 vs 700 → +20 kg
• 60 hp AWD: 770 vs 760 → +10 kg
• 64 hp FWD: 720 vs 710 → +10 kg
• 64 hp AWD: 770 vs 760 → +10 kg

The automatic tax is largest on the weakest engine (+30 kg on 54 hp FWD) and smallest on the turbo AWD pairs (+10 kg).

Performance, mpg, reliability

0–100, top speed, city / highway / combined consumption, CO₂, eco class, and wheel sizes are not measured on every version. There is no mpg number to rank economy; the only fuel facts are grade (95 on 54 hp, 92 on both turbos) and tank (30 L). Reliability and typical problems are not measured in this dataset.

Which version to choose

Default pick: 0.7 MT 64 hp FWD. Highest power (64 hp / 47 kW), highest torque (106 Nm), best mass-to-power (≈11.1 kg/hp), 710 kg, 5-speed Manual, 175 mm, fuel 92. Versus 0.7 MT 54 hp it is 30 kg lighter and 10 hp / 43 Nm stronger. Versus 0.7 MT 60 hp FWD it gives up 10 kg of lightness (710 vs 700) for +4 hp and +23 Nm, and it uses the 4-valve 658 turbo instead of the 2-valve 657.

If you want the lightest car: 0.7 MT 60 hp FWD at 700 kg. That is 10 kg under the 64 hp FWD manual and 70 kg under the 54 hp automatic. You trade 4 hp and 23 Nm for that 10 kg.

If you want an automatic without AWD: 0.7 AT 64 hp FWD. Same 720 kg as 0.7 AT 60 hp FWD, but 4 speeds instead of 3, and 106 Nm instead of 83 Nm. Do not buy 0.7 AT 54 hp unless you specifically want the No-boost 658 and fuel 95: it is also 770 kg, matching the heaviest AWD automatics, with 54 hp and 63 Nm.

If you want AWD: 0.7 MT 64 hp AWD (driver who will use a Manual 5) or 0.7 AT 64 hp AWD (Automatic 4, 770 kg). Both have 185 mm clearance. Avoid pairing AWD with the 60 hp engine unless you accept 83 Nm in a 760–770 kg car: that is ≈12.7–12.8 kg/hp, close to the naturally aspirated manuals.

Skip unless you want the naturally aspirated 658: 0.7 MT 54 hp and 0.7 AT 54 hp. They are the only versions with No boost, compression 10.5, fuel 95, independent rear spring, and a published 960 kg gross. They are also the worst kg/hp in the catalogue.

There is no second generation to “wait for.” Every comparison above is inside the same 1999–2009 Mini 5-doors run. Prices are not in the data, so “what the extra money buys” here means what the extra kilograms, millimetres, horsepower, and newton-metres buy: +10 mm and AWD cost 50–60 kg; the step from 54 to 64 hp costs no extra kerb on the FWD manuals (it is lighter); the step from 60 to 64 hp on FWD is 10 kg on the manual and 0 kg on the automatic.
