Proton Tiara: which version to buy
The Proton Tiara was sold in one generation (1996–2000) as a Mini 5-doors with two catalogue versions, both named 1.1 MT. The choice is not between generations. It is between the 1.1 MT with 54 hp and the 1.1 MT with 60 hp.
The Proton Tiara was sold in one generation (1996–2000) as a Mini 5-doors with two catalogue versions, both named 1.1 MT. The choice is not between generations. It is between the 1.1 MT with 54 hp and the 1.1 MT with 60 hp. Both use the same 1124 cm³ Gasoline engine layout (4 cylinders, Inline, 2 valves per cylinder, boost: No), the same 88 Nm peak, the same 5-speed Manual gearbox, and the same FWD layout. The 60 hp 1.1 MT is the quicker, more fully measured car. The 54 hp 1.1 MT is the one specified for 92 fuel and a higher compression ratio. Where a number is missing below, it is not measured.
Specs compared: 54 hp vs 60 hp 1.1 MT
| Version | hp | Nm | cm³ | Fuel | Cylinders / layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 1.1 MT (54 hp) | 54 | 88 | 1124 | 92 | 4, Inline | No | Manual, 5 | FWD |
| 1.1 MT (60 hp) | 60 | 88 | 1124 | 95 | 4, Inline | No | Manual, 5 | FWD |
Both versions are 1.1 MT. Distinguish them by power: 54 hp versus 60 hp. Peak torque is identical at 88 Nm at 3800 rpm. Displacement is identical at 1124 cm³. Cylinder count, Inline layout, 2 valves per cylinder, and boost: No are identical. Fuel system on both is Central injection (single-point or single- point). Front suspension on both is Independent, spring. Front brakes on both are Disc.
What actually differs in the engine sheet is output, compression, fuel grade, and (for the 60 hp car) a complete chassis and economy set.
- 1.1 MT 54 hp: 40 kW at 6220 rpm, compression 9.7, fuel 92, 0–100 13.2 s, top speed 158 km/h. City / highway / mixed consumption: not measured. Kerb weight, gross weight, ground clearance, wheels, rear suspension, rear brakes: not measured.
- 1.1 MT 60 hp: 44 kW at 6200 rpm, compression 9.4, fuel 95, 0–100 12.7 s, top speed 167 km/h. Consumption 7.1 / 4.7 / 6.1 L/100 km (city / highway / mixed). Kerb 691 kg, gross 1160 kg, ground clearance 110 mm. Rear suspension Semi-independent, torsion. Rear brakes Drum. Wheels: not measured.
Arithmetic on those figures:
- Power gap: 60 − 54 = 6 hp (+11.1%). In kW: 44 − 40 = 4 kW (+10%).
- Specific output: 54 / 1.124 ≈ 48.0 hp/L versus 60 / 1.124 ≈ 53.4 hp/L. The 60 hp 1.1 MT extracts about 5.4 hp more per litre from the same 1124 cm³.
- Torque is not the differentiator: both peak at 88 Nm at the same 3800 rpm. The extra 6 hp is a higher-rev power figure (6220 vs 6200 rpm — 20 rpm apart), not a fatter mid-range number in this data.
- Compression: 9.7 on the 54 hp car versus 9.4 on the 60 hp car. The lower-output 1.1 MT is the higher-compression spec (+0.3). That lines up with fuel 92 versus 95.
- Bore × stroke is the same 72 × 69 on both. Tank is 43 L on both. Drive, gearbox type, and gear count do not change.
There is no second generation to “buy up into.” Generation count is 1. Body type is Mini 5-doors for both versions. Production window is 1996-01-01 to 2000-12-31 for the generation and for each 1.1 MT.
Performance and mpg: what the extra 6 hp actually buys
0–100 km/h. The 60 hp 1.1 MT is 0.5 s quicker (12.7 vs 13.2). That is a 3.8% cut in the published sprint, not a class change.
Top speed. 167 versus 158 km/h: +9 km/h (+5.7%). If the question is “which Tiara is the faster 1.1 MT,” the answer is the 60 hp car on both 0–100 and top speed.
Fuel consumption. Only the 60 hp 1.1 MT has measured figures: city 7.1, highway 4.7, mixed 6.1. For the 54 hp 1.1 MT, city, highway, and mixed are not measured. You cannot claim the 54 hp car uses less fuel from this catalogue. You also cannot claim it uses more. The only honest mpg comparison is: one version has a full set, the other does not.
CO2 and eco class. Not measured on both 1.1 MT versions.
Range from the tank (60 hp only). Mixed 6.1 L/100 km and tank 43 L give a paper range of 43 / 6.1 × 100 ≈ 705 km if the tank were used in full at the mixed rate. Highway 4.7 L/100 km would be 43 / 4.7 × 100 ≈ 915 km. City 7.1 L/100 km would be 43 / 7.1 × 100 ≈ 606 km. These are arithmetic on the given mixed/highway/city rates and the 43 L tank, not a tested range. The 54 hp 1.1 MT has the same 43 L tank, but consumption is not measured, so range is not measured.
Dimensions, weight, and what you can load
Kerb weight. 691 kg on the 60 hp 1.1 MT. Not measured on the 54 hp 1.1 MT. Power-to-weight can be calculated only for the 60 hp car: 691 / 60 ≈ 11.5 kg per hp, or 60 / 0.691 ≈ 86.8 hp per tonne. Do not invent a kerb figure for the 54 hp 1.1 MT to “compare” weight per horsepower.
Gross weight. 1160 kg on the 60 hp 1.1 MT. Not measured on the 54 hp 1.1 MT. Payload on the measured car: 1160 − 691 = 469 kg.
Ground clearance. 110 mm on the 60 hp 1.1 MT. Not measured on the 54 hp 1.1 MT.
Wheels. Not measured on both versions.
Tank. 43 L on both.
Chassis completeness. The 60 hp 1.1 MT is the version with rear suspension (Semi-independent, torsion) and rear brakes (Drum) written down. The 54 hp 1.1 MT has front Independent, spring and front Disc; rear suspension and rear brakes are not measured. That is a documentation gap in the data, not a reason to invent a rear layout for the 54 hp car.
Which version to choose
Choose the 1.1 MT (60 hp) if you want the faster, fully specified Tiara. It is 6 hp and 4 kW stronger, 0.5 s quicker to 100 km/h, 9 km/h higher in top speed, and the only version with measured consumption (7.1 / 4.7 / 6.1), kerb 691 kg, gross 1160 kg (469 kg payload), and 110 mm clearance. Specific output is 53.4 hp/L versus 48.0 hp/L. Fuel is 95. Rear axle and rear brakes are specified (Semi-independent, torsion; Drum).
Choose the 1.1 MT (54 hp) if the deciding number is fuel grade, not sprint time. It is specified for 92 rather than 95, and compression is 9.7 versus 9.4. Torque is the same 88 Nm. Gearbox, drive, displacement, cylinder layout, boost (No), and tank (43 L) do not change. You give up 6 hp, 0.5 s on 0–100, and 9 km/h on top speed, and you accept that consumption, kerb, gross, clearance, wheels, rear suspension, and rear brakes are not measured.
There is no generation decision. One generation, Mini 5-doors, two 1.1 MT lines, same years. Nothing in the data describes a restyle as a separate generation. Nothing in the data prices either car, so “what the extra money buys” can only mean what the extra 6 hp buys in the table: +11.1% power, +5.4 hp/L, −0.5 s to 100, +9 km/h top speed, and a complete economy/weight sheet that the 54 hp 1.1 MT does not have.
Reliability / problems. This catalogue does not contain failure rates, recall counts, or workshop data. Those topics are not measured here. The comparison that is measured is the two 1.1 MT rows: same 1124 cm³ Gasoline Inline-4, same 88 Nm, same Manual 5 and FWD; different power, compression, fuel grade, sprint, and how complete the chassis and mpg columns are.
Short answer. If the Tiara you can inspect is a 1.1 MT, read the power figure. 60 hp is the quicker, heavier-documented buy. 54 hp is the 92-fuel, higher-compression spec with the same torque and the same gearbox, but with economy, weight, and clearance not measured.
