Rover Mini: which version to buy and why

The Rover Mini in this catalogue is a single-generation Cabrio sold from 1989-01-01 to 2000-12-31, with eight versions and no second generation to step into. The buying question is therefore not “which generation” but which of the eight engines, gearboxes and weights inside that one Cabrio.

The Rover Mini in this catalogue is a single-generation Cabrio sold from 1989-01-01 to 2000-12-31, with eight versions and no second generation to step into. The buying question is therefore not “which generation” but which of the eight engines, gearboxes and weights inside that one Cabrio. All eight are Gasoline, 4 Inline cylinders, 2 valves per cylinder, No boost, Front, transverse, FWD, 4-speed, 34 l tank, 150 mm ground clearance, Independent, spring suspension front and rear, Disc front brakes and Drum rear. Wheel sizes are not measured on every version. What actually changes is displacement (998–1275 cm³), power (41–63 hp), torque (68–95 Nm), injection versus Carburetor, Manual versus Automatic, 0–100 km/h (11.2–17 s where measured), top speed (129–148 km/h), kerb weight (625–750 kg where measured) and the few fuel figures that exist.

Generations: one Cabrio, eight versions, nothing restyled as a later generation

1 generation (1989-01-01 – 2000-12-31), Cabrio, 8 versions. There is no later generation in the data, so a later year does not buy a new platform, a new body or a different drivetrain layout. The spread you pay for is inside this generation: 1.0 MT (41 hp) versus seven 1.3-litre cars; Manual versus Automatic; Carburetor versus Central injection (single-point or single- point) versus Distributed injection (multi-point); kerb weight from 625 kg to 750 kg. Treat the eight rows as the whole market.

Specs that decide the buy: engine, gearbox, drive

Specific output from those columns: 1.3 MT / 1.3 AT at 63 hp give 63 / 1.273 ≈ 49.5 hp per litre. 1.3 MT at 61 hp gives 61 / 1.275 ≈ 47.8 hp/l. 1.3 MT at 53 hp: 53 / 1.273 ≈ 41.6 hp/l. 1.0 MT: 41 / 0.998 ≈ 41.1 hp/l. 1.3 MT / 1.3 AT at 50 hp: 50 / 1.274 ≈ 39.2 hp/l — the weakest 1.3 by specific output, below the 998 cm³ car.

Torque peaks tell a different story than peak hp. The 63 hp 1.3 MT and 1.3 AT need 3900 rpm for 95 Nm. The 53 hp 1.3 MT makes 92 Nm already at 2600 rpm — 3 Nm less, 1300 rpm earlier. The 50 hp pair make 89 Nm at 2600 rpm. 1.3 MT (61 hp, Carburetor) sits in the middle: 91 Nm at 3000 rpm. 1.0 MT is 68 Nm at 2500 rpm, 27 Nm behind the 95 Nm cars.

Compression ratio (data, not a guess): 10.5 on the 50 hp 1274 cm³ pair, 10.3 on 1.0 MT, 10.1 on the 63 hp 1273 cm³ cars, 9.75 on the Carburetor 1.3 MT (61 hp), 9.4 on the 53 hp 1.3 MT. Bore × stroke is 70.6 × 81.3 mm on the 1273 cm³ engines, 70.6 × 81.33 mm on 1274/1275, and 64.58 × 76.2 mm on the 998 cm³ 1.0 MT. Fuel is 95 on every version.

Performance, mpg and what the extra horsepower actually buys

Fastest 0–100 km/h in the data: 11.2 s on 1.3 MT (61 hp, Carburetor) — not on the 63 hp cars. Those 63 hp 1.3 MT versions both take 12.5 s. The 63 hp 1.3 AT is 12.7 s (0.2 s slower than its Manual twins). 1.3 MT (50 hp) is 13.4 s. 1.3 MT (53 hp) is 13.8 s — 1.3 s slower than the 63 hp Manuals, 2.6 s slower than the 61 hp Carburetor. 1.0 MT is 17.0 s, 5.8 s behind the 61 hp car. 1.3 AT (50 hp): 0–100 not measured.

Top speed: three cars share the catalogue peak of 148 km/h — 1.3 MT (63 hp, 700 kg), 1.3 AT (63 hp), 1.3 MT (61 hp). The other 63 hp 1.3 MT (750 kg) is 145 km/h, 3 km/h less with 50 kg more kerb. 1.3 MT (53 hp): 143 km/h. 1.3 MT (50 hp): 140 km/h. 1.3 AT (50 hp): 132 km/h, 8 km/h below its Manual twin and 16 km/h below the 148 km/h cars. 1.0 MT: 129 km/h.

Fuel: four versions have figures; four do not. 1.0 MT is the measured economy leader: city 6.1, highway 4.7, mixed 6.9 l/100 km. 1.3 MT (61 hp, Carburetor): city 7.6, highway 5.7, mixed 7.3. 1.3 MT (50 hp): city 7.6, highway 5.2, mixed 8.4 — same city as the 61 hp car, 0.5 l/100 km better on the highway, 1.1 l/100 km worse mixed. 1.3 AT (50 hp): city 8, highway 6, mixed 9.2 — versus its 50 hp Manual twin that is +0.4 city, +0.8 highway, +0.8 mixed. Mixed on the 50 hp Automatic is 2.3 l/100 km above 1.0 MT and 1.9 above the 61 hp Manual. For both 63 hp 1.3 MT cars, the 53 hp 1.3 MT, and the 63 hp 1.3 AT, city / highway / mixed are not measured. CO2 and eco class are not measured on all eight.

Dimensions, weight and kg per horsepower

Ground clearance is 150 mm on every version. Tank is 34 l on every version. Wheel size is not measured on every version. Gross weight is 1070 kg on the heaviest 63 hp 1.3 MT, 1050 kg on the 53 hp 1.3 MT and on both remaining 63 hp cars (Manual 700 kg and Automatic), 1000 kg on the 50 hp pair, the 61 hp 1.3 MT and 1.0 MT.

Kerb, where measured:

• 1.0 MT: 625 kg → 625 / 41 ≈ 15.2 kg/hp (worst power-to-weight).
• 1.3 MT (50 hp): 645 kg → 645 / 50 ≈ 12.9 kg/hp.
• 1.3 MT (61 hp): 695 kg → 695 / 61 ≈ 11.4 kg/hp.
• 1.3 MT (53 hp) and both 63 hp cars at 700 kg: 700 / 53 ≈ 13.2 kg/hp; 700 / 63 ≈ 11.1 kg/hp (best among measured kerbs).
• 1.3 MT (63 hp, 750 kg): 750 / 63 ≈ 11.9 kg/hp — 50 kg more than the 700 kg 63 hp twin, 0.8 kg/hp worse, and that matches the 3 km/h lower top speed (145 vs 148).
• 1.3 AT (50 hp): kerb not measured; gross still 1000 kg.

Payload from kerb and gross where both exist: 1.0 MT 1000 − 625 = 375 kg; 50 hp 1.3 MT 1000 − 645 = 355 kg; 61 hp 1.3 MT 1000 − 695 = 305 kg; 53 hp and 700 kg 63 hp cars 1050 − 700 = 350 kg; 750 kg 63 hp 1.3 MT 1070 − 750 = 320 kg. The lightest car carries the most extra mass to gross.

Which version to choose

If the number that matters is 0–100: buy 1.3 MT (61 hp). It is the only Carburetor 1.3 in the table, 1275 cm³, 61 hp, 91 Nm, 11.2 s, 148 km/h, mixed 7.3 l/100 km, 695 kg. It beats both 63 hp Manuals by 1.3 s to 100 km/h despite 2 hp less, because those 63 hp cars are 700 or 750 kg. Mixed fuel is measured; on the 63 hp cars it is not measured, so you cannot claim they are thirstier — only that this Carburetor row has a number and they do not.

If the number that matters is peak power and kg/hp: buy 1.3 MT (63 hp, 700 kg, 148 km/h), not the 750 kg twin. Same 63 hp, 95 Nm, 12.5 s, Central injection, compression 10.1. The 700 kg car is 50 kg lighter, 11.1 vs 11.9 kg/hp, and 148 vs 145 km/h. Nothing in the data makes the 750 kg car faster. Same gearbox (Manual 4), same FWD. Distinguish it from the other 63 hp 1.3 MT by 750 kg / 145 km/h versus 700 kg / 148 km/h.

If you want Automatic and still 63 hp: 1.3 AT (63 hp) is the only Automatic that keeps 148 km/h and a measured 12.7 s. It is also the only version with Distributed injection (multi-point). Versus the 700 kg 63 hp 1.3 MT: same 63 hp and 95 Nm, +0.2 s to 100, same 148 km/h, same 700 kg. Versus 1.3 AT (50 hp): +13 hp, +6 Nm, +16 km/h (148 vs 132), and 0–100 is measured (12.7 s) on the 63 hp Automatic and not measured on the 50 hp Automatic. Fuel on the 63 hp Automatic is not measured; on the 50 hp Automatic mixed is 9.2 l/100 km.

Do not buy 1.3 AT (50 hp) for pace. 50 hp, 89 Nm, 132 km/h, 0–100 not measured, mixed 9.2, kerb not measured. It is the slowest 1.3 by top speed and the thirstiest measured mixed figure. The Automatic costs you 8 km/h and 0.8 l/100 km mixed versus 1.3 MT (50 hp) at the same 50 hp.

1.3 MT (50 hp) is the lightest measured 1.3 (645 kg) but not the one to buy for speed. 13.4 s, 140 km/h, mixed 8.4 — 2.2 s and 8 km/h behind the 61 hp Carburetor, 1.1 l/100 km worse mixed. Specific output 39.2 hp/l is the lowest in the set. Buy it only if you need a 1.3 Manual with measured consumption and the lowest 1.3 kerb; not if you need the best 0–100.

1.3 MT (53 hp) sits in a hole: more power than the 50 hp Manual, worse 0–100. 53 vs 50 hp, 92 vs 89 Nm, but 13.8 vs 13.4 s and 700 vs 645 kg. The extra 3 hp does not offset 55 kg. Top speed 143 vs 140 km/h is the only clear gain. Fuel on the 53 hp car is not measured. Compression 9.4 is the lowest in the catalogue. Prefer 1.3 MT (50 hp) if you want a measured mpg 1.3 Manual; prefer a 63 hp 1.3 MT if you want 12.5 s.

1.0 MT is the economy and payload buy, not the performance buy. 41 hp, 68 Nm, 17.0 s, 129 km/h, mixed 6.9, 625 kg, 375 kg to gross. Versus the 61 hp 1.3 MT: −20 hp, +5.8 s, −19 km/h, −0.4 mixed, −70 kg. Versus the 700 kg 63 hp 1.3 MT: −22 hp, +4.5 s, −19 km/h, fuel on the 63 hp car not measured. City 6.1 / highway 4.7 are the best measured. There is no Automatic 1.0 in the data.

What “extra money” can buy inside this generation (arithmetic only; prices are not in the data). Stepping from 1.0 MT to 1.3 MT (61 hp) buys 20 hp, 23 Nm, 5.8 s, 19 km/h, and 0.4 l/100 km more mixed. Stepping from 1.3 MT (50 hp) to 1.3 MT (61 hp) buys 11 hp, 2 Nm, 2.2 s, 8 km/h, and 1.1 l/100 km less mixed — the Carburetor 1.3 is both quicker and more economical on the mixed figure than the 50 hp injected 1.3. Stepping from 61 hp to 63 hp 1.3 MT (700 kg) buys 2 hp and 4 Nm, loses 1.3 s to 100 km/h, matches 148 km/h, and drops measured mixed (not measured on 63 hp). Stepping from 63 hp Manual to 63 hp Automatic buys multi-point injection and two-pedal use for 0.2 s. Stepping to the 750 kg 63 hp 1.3 MT buys 50 kg and loses 3 km/h; it does not buy acceleration.

Short list. Pace: 1.3 MT (61 hp). Peak power and best measured kg/hp: 1.3 MT (63 hp, 700 kg, 148 km/h). Automatic without dropping to 132 km/h: 1.3 AT (63 hp). Lowest measured use and lightest kerb: 1.0 MT. Avoid as a “more power” upgrade: 1.3 MT (53 hp) versus 1.3 MT (50 hp). Avoid if you care about measured 0–100 or top speed: 1.3 AT (50 hp). There is no second generation in the data, so none of these choices is a later-generation car.
