Engine: power per litre and what extra displacement buys

Specific output (hp ÷ litres) ranks the petrol cars, then the diesels:

• 1.8 MT 135 hp / 1.834 L = 73.6 hp/L (peak at 6500 rpm; 164 Nm at 5500)
• 1.6 MT 113 hp and 1.6 AT 113 hp / 1.597 L = 70.8 hp/L (6000 rpm; 137 Nm at 5000)
• 1.8 MT 115 hp / 1.834 L = 62.7 hp/L (5500 rpm; 160 Nm at 4500)
• 1.5 MT 90 hp and 1.5 AT 90 hp / 1.468 L = 61.3 hp/L
• 1.6 MT 95 hp / 1.597 L = 59.5 hp/L
• 1.5 MT 87 hp and 1.5 AT 87 hp / 1.468 L = 59.3 hp/L
• 1.3 MT 75 hp / 1.298 L = 57.8 hp/L
• 2.0 MT 82 hp Turbo Diesel / 1.998 L = 41.0 hp/L
• 2.0 MT 68 hp Diesel / 1.998 L = 34.0 hp/L

The 135 hp 1.8 MT is not “just a bigger 1.6”: it makes +22 hp versus the 113 hp 1.6 MT / 1.6 AT (+19%) and +40 hp versus the 95 hp 1.6 MT (+42%). Versus the 115 hp 1.8 MT sharing the same 1834 cc and 81 × 89 bore/stroke, the 135 hp car adds 20 hp and 4 Nm, raises compression from 10 to 10.5, and moves peak power from 5500 to 6500 rpm.

Stepping down from 1.8 to 1.6: the 113 hp 1.6 MT is 22 hp and 27 Nm behind the 135 hp 1.8 MT, but only 2 hp and 23 Nm behind the 115 hp 1.8 MT. The 95 hp 1.6 MT is another 18 hp below the 113 hp 1.6 MT, with almost the same torque (135 vs 137 Nm) arriving at the same 5000 rpm — the 95 hp and 113 hp 1.6s are close on twist, far apart on peak power.

From 1.6 to 1.5: 1468 cc versus 1597 cc is 129 cc less. The 90 hp 1.5 MT is 5 hp and 9 Nm behind the 95 hp 1.6 MT, and 23 hp behind the 113 hp 1.6 MT. The 87 hp 1.5 MT / 1.5 AT sit 3 hp and 6 Nm below the 90 hp pair. Valve count splits the 1.5s: 90 hp cars use 2 valves per cylinder (75.5 × 82); 87 hp cars use 3 (75 × 82). Compression is 9.2 on all four 1.5s versus 10 on all three 1.6s.

The 1.3 MT is the smallest petrol: 1298 cc, 75 hp, 108 Nm at 3000 rpm, 3 valves, compression 9.5. Versus the 87 hp 1.5 MT that is −12 hp and −12 Nm for 170 cc less. Versus the 135 hp 1.8 MT it is −60 hp and −56 Nm.

Diesel 2.0 MT cars are a different product: 1998 cc, compression 22.2, 2 valves, fuel Diesel. The naturally aspirated 68 hp 2.0 MT makes 123 Nm at 3000 rpm. The Turbo 82 hp 2.0 MT adds 14 hp and 49 Nm (172 Nm at 2500 rpm). That 172 Nm is the highest torque in the list, 8 Nm above the 135 hp 1.8 MT (164 Nm) and 49 Nm above the NA diesel. Specific power stays last: 34.0 and 41.0 hp/L.

Boost is No on every Gasoline version. The only Turbo is the 82 hp 2.0 MT. Injection is Distributed injection (multi-point) on all petrols; Diesel injection is not measured.

Performance and mpg: 0–100, top speed, fuel use

City, highway, mixed consumption, CO2, and eco class are not measured on every version. Mpg cannot be used to pick a Wira from this dataset.

Measured 0–100 km/h and top speed:

The 135 hp 1.8 MT is 1.4 s and 11 km/h quicker than the 115 hp 1.8 MT, 1.8 s and 16 km/h quicker than the 113 hp 1.6 MT, and 3.5 s and 39 km/h quicker than the 1.3 MT.

Between the two 1.6 manuals, 18 hp buys only 0.5 s and 6 km/h (10.8 s / 187 vs 11.3 s / 181). Between the two 1.5 manuals, 3 hp buys 0.2 s and 2 km/h. The 1.3 MT is only 0.2 s slower than the 87 hp 1.5 MT and 0.4 s slower than the 90 hp 1.5 MT, with a larger speed gap (164 vs 171 and 173 km/h).

Automatic cost in the one pair with both times: 87 hp 1.5 AT (Automatic 4) is 14.6 s / 165 km/h versus 87 hp 1.5 MT (Manual 5) at 12.3 s / 171 km/h — +2.3 s and −6 km/h for the same 87 hp and 120 Nm. The 90 hp 1.5 AT (Automatic 3) and 113 hp 1.6 AT (Automatic 4) have 0–100 and top speed not measured, so they cannot be ranked on sprint.

Diesels: Turbo 2.0 MT 82 hp is 4.2 s and 10 km/h quicker than NA 2.0 MT 68 hp (14.3 / 170 vs 18.5 / 160). The Turbo diesel is still 2.0 s slower than the 1.3 MT petrol and 5.3 s slower than the 135 hp 1.8 MT, despite more torque.

Dimensions and weight: kg per horsepower

Wheel size is not measured on all 12. Tank is 50 L on all 12. Ground clearance is 135 mm except the 87 hp 1.5 MT and 87 hp 1.5 AT, where it is not measured.

Kerb / gross and kg per hp (kerb ÷ hp), where kerb exists:

The 135 hp 1.8 MT is the lightest-for-power car: 8.0 kg/hp, same 1075 kg kerb as the 90 hp 1.5 MT but 45 hp more. The 115 hp 1.8 MT is 105 kg heavier than the 135 hp 1.8 MT (1180 vs 1075) with 20 hp less — the slower 1.8 is the worse power-to-weight of the two.

The 113 hp 1.6 MT is 75 kg heavier than the 95 hp 1.6 MT (1145 vs 1070) for 18 hp. Payload (gross − kerb) is 440 kg on the 113 hp 1.6 MT versus 515 kg on the 95 hp 1.6 MT and 475 kg on the 135 hp 1.8 MT. The 115 hp 1.8 MT payload is 335 kg (1515 − 1180), the smallest among measured petrols.

Lightest kerb is the 87 hp 1.5 AT at 980 kg, then 87 hp 1.5 MT at 1010 kg. Heaviest kerb is the 115 hp 1.8 MT at 1180 kg. Gross peaks at 1585 kg on both 1.6 manuals and the 1.6 AT.

Brakes that change the choice: only the 135 hp 1.8 MT has Ventilated disc front and Drum rear. The 113 hp 1.6 MT, 1.6 AT, and 115 hp 1.8 MT use Disc front and Disc rear. All 1.3, 1.5, 95 hp 1.6, and both diesels use Disc front and Drum rear. Rear suspension is Independent, spring where measured; on both 87 hp 1.5s rear suspension is not measured. Front is Independent, spring on all 12.

Which version to choose

Want the strongest measured sprint. Buy the 1.8 MT 135 hp: 9 s, 203 km/h, 73.6 hp/L, 8.0 kg/hp, Ventilated disc front. It is the only Wira in this list under 10 s. Fuel 92. Manual 5. No Automatic twin exists in the data.

Want 1.8 displacement without the 135 hp tune. The 1.8 MT 115 hp is 1.4 s slower, 11 km/h down, 105 kg heavier, Disc/Disc instead of Ventilated disc/Drum. Torque is close (160 vs 164 Nm) and arrives earlier (4500 vs 5500 rpm). Choose it only if you specifically want that 115 hp map; on the numbers the 135 hp 1.8 MT dominates.

Want a 1.6 with the higher output. The 1.6 MT 113 hp (10.8 s, 187 km/h, Disc/Disc, 1145 kg) is the measured-performance pick in 1597 cc. Gap to 135 hp 1.8 MT: +1.8 s, −16 km/h, +70 kg. Gap to 95 hp 1.6 MT: −0.5 s, +6 km/h, +75 kg, and rear Disc instead of Drum.

Want a 1.6 Automatic. Only the 1.6 AT 113 hp: same 113 hp / 137 Nm as the 113 hp 1.6 MT, Automatic 4, Disc/Disc, gross 1585 kg, kerb not measured, 0–100 not measured, top speed not measured. You cannot prove from this table that the automatic is slower; you also cannot prove it matches the 10.8 s manual.

Want the cheaper-feeling 1.6. The 1.6 MT 95 hp: 11.3 s, 181 km/h, 1070 kg, Drum rear. Versus 113 hp 1.6 MT you give up 18 hp and rear discs for 75 kg less kerb and 0.5 s. Versus 90 hp 1.5 MT you gain 5 hp, 9 Nm, 8 km/h, and 0.8 s, at 5 kg less than that 1.5’s 1075 kg.

Want 1.5 petrol, manual. Two 1.5 MT names: 90 hp (12.1 s, 173 km/h, 95 octane, 2 valves, 1075 kg) versus 87 hp (12.3 s, 171 km/h, fuel not measured, 3 valves, 1010 kg, clearance not measured). The 90 hp car is 3 hp and 6 Nm up, 65 kg heavier, 0.2 s and 2 km/h quicker. If octane 95 is acceptable, the 90 hp 1.5 MT is the faster 1.5 manual; if kerb mass is the goal, the 87 hp 1.5 MT is 65 kg lighter.

Want 1.5 Automatic. Two 1.5 AT names. 87 hp Automatic 4: 14.6 s, 165 km/h, 980 kg — lightest Wira listed, 2.3 s slower than its 87 hp 1.5 MT twin. 90 hp Automatic 3: 90 hp, 126 Nm, 95 octane, 3 speeds not 4; 0–100, top speed, kerb, and gross not measured. If you need a measured automatic time, only the 87 hp 1.5 AT supplies one. If you need 90 hp with Automatic, only the 90 hp 1.5 AT exists — and it is a 3-speed, with sprint not measured.

Want the smallest petrol. 1.3 MT 75 hp: 12.5 s, 164 km/h, 1070 kg, 14.3 kg/hp, Drum rear, 92 octane. It is 0.2 s off the 87 hp 1.5 MT despite 12 hp less, because that 1.5 is only 60 kg lighter (1010 vs 1070). Versus the 135 hp 1.8 MT it is 3.5 s and 39 km/h down at almost the same kerb (1070 vs 1075).

Want Diesel torque. The Turbo 2.0 MT 82 hp (172 Nm at 2500 rpm, 14.3 s, 170 km/h, 1175 kg) is the torque leader. Versus NA 2.0 MT 68 hp: +14 hp, +49 Nm, −4.2 s, +10 km/h, +25 kg. Neither diesel beats a 1.3 petrol on 0–100. Buy diesel only for the 172 Nm (Turbo) or 123 Nm (NA) and Diesel fuel; not for sprint or top speed (160–170 km/h).

Problems / reliability as a buying filter. This dataset does not list faults, crash tests, or service intervals. What it does show: every petrol uses Distributed injection (multi-point) and No boost; the only Turbo is the 82 hp 2.0 MT. Compression spans 9.2 (all 1.5s) to 10.5 (135 hp 1.8 MT) on petrol and 22.2 on both diesels. Rear drums are the majority; rear discs are only the 113 hp 1.6 MT, 1.6 AT, and 115 hp 1.8 MT. Several buyer-critical figures stay not measured: all mpg/CO2, both Automatic high-power sprints (1.6 AT, 90 hp 1.5 AT), two kerb weights, two clearances, all wheel sizes.

Short pick list. Fastest measured Coupe: 1.8 MT 135 hp. Best measured 1.6: 1.6 MT 113 hp. Lightest: 1.5 AT 87 hp (980 kg). Highest torque: 2.0 MT 82 hp Turbo (172 Nm). Smallest petrol: 1.3 MT. Automatic with a published 0–100: only 1.5 AT 87 hp. Same name, different car — always match 1.8 MT to 135 vs 115 hp, 1.6 MT to 113 vs 95 hp, 1.5 MT to 90 vs 87 hp, 1.5 AT to 90 vs 87 hp, 2.0 MT to 82 Turbo vs 68 No.
