All Gasoline and Hybrid versions use fuel 95. Diesel versions use Diesel. Gasoline 2.5 AT / 3.7 AT injection is Distributed injection (multi-point); 5.6 AT is Direct injection (direct); 2.1 AT and 3.0 AT injection not measured. Engine position on restyle cars with a figure is Front, longitudinal; several 1st-generation cars list it not measured.
Specific output (hp per litre, displacement in litres from cm³): restyle 2.5 AT 88.5 hp/l; 3.7 AT 333 hp 90.1 hp/l; 3.7 AT 330 hp 89.3 hp/l; 3.7 AT 320 hp 86.6 hp/l; 3.5 AT 306 hp 87.5 hp/l; 5.6 AT 408 hp 73.5 hp/l; 5.6 AT 420 hp 75.0 hp/l; 2.1 AT 79.3 hp/l; 3.0 AT 79.5 hp/l. The 3.7 AT 333 hp AWD is the densest Gasoline output in the file; the 5.6 AT 8-cylinder cars buy displacement and torque (550–565 Nm), not hp per litre.
Performance, mpg and horsepower: what the extra displacement buys
0–100 km/h. Fastest measured: restyle 5.6 AT 420 hp RWD 4.7 s (both 80 L and 76 L tanks). AWD on the same 420 hp costs 0.1 s (4.8 s, 80 L) or 0.2 s (4.9 s, 76 L). Pre-restyle 5.6 AT 408 hp RWD is 5.2 s, AWD 5.3 s — 0.5 s slower than the later 420 hp RWD. Restyle 3.5 AT Hybrid matches the 408 hp AWD 5.6 AT at 5.3 s with 102 hp less. Restyle 3.7 AT 330 hp RWD (80 L) is 5.8 s; the 76 L twin is 5.9 s. 3.7 AT 333 hp AWD is 6.3 s in both blocks — 0.5 s slower than the 330 hp RWD (80 L) despite +3 hp, because kerb mass is 1845 kg versus 1754 kg (+91 kg). 3.7 AT 320 hp is 6.2 s both blocks. 3.0 AT Diesel 6.9 s. 2.1 AT 8.9 s. 2.5 AT 9.2 s both blocks. The 2.5 AT to 3.7 AT 330 hp RWD step is −3.4 s. The 3.7 AT 330 hp RWD to 5.6 AT 420 hp RWD step is −1.1 s.
Top speed. 250 km/h: restyle 5.6 AT 408 hp AWD; 1st-generation 5.6 AT 408 hp AWD and RWD; 3.0 AT; both 3.5 AT; 1st-generation 3.7 AT 320 hp. Restyle 3.7 AT 320 hp 250 km/h; restyle 3.7 AT 333 hp AWD 246 km/h; 2.5 AT 231 km/h; 2.1 AT 220 km/h. Not measured: restyle 3.7 AT 330 hp (both tanks); restyle 5.6 AT 420 hp (all four).
Fuel (l/100 km, city / highway / mixed). Lowest mixed with a number: restyle 2.1 AT 5.9 / 4.4 / 4.9. Restyle 3.5 AT Hybrid 8.7 / 5.3 / 6.2. 3.0 AT 10.3 / 5.9 / 7.5. Restyle 2.5 AT 13.3 / 7.9 / 9.9 (same as 1st-generation 2.5 AT). Restyle 3.7 AT 320 hp 14.9 / 7.4 / 10.2 versus 1st-generation 3.7 AT 320 hp 15.8 / 7.9 / 10.8 (−0.6 mixed after restyle). Restyle 3.7 AT 333 hp AWD 15.3 / 8.4 / 10.9. Restyle 3.7 AT 330 hp 13.1 / 9.1 / 11.2 (both tanks). Restyle 5.6 AT 408 hp AWD 18.7 / 8.9 / 12.5. Restyle 5.6 AT 420 hp RWD 14.7 / 9.8 / 12.4; AWD 14.7 / 10.2 / 13.1. 1st-generation 5.6 AT 408 hp RWD 17.5 / 8.8 / 12. Not measured: 1st-generation 2.1 AT and 3.5 AT consumption. Versus restyle 2.5 AT, restyle 2.1 AT uses 5.0 l/100 km less mixed; restyle 3.5 AT uses 3.7 less mixed; restyle 5.6 AT 420 hp RWD uses 2.5 more mixed.
CO2. Restyle 2.1 AT 129 g/km. Restyle 3.5 AT 145 g/km. Restyle 3.7 AT 320 hp 235 g/km. 1st-generation 3.7 AT 333 hp AWD 235 g/km; 1st-generation 3.7 AT 320 hp 249 g/km. All other CO2 not measured.

Restyle 5.6 AT 420 hp RWD 80 L: Euro 4; same power RWD 76 L: Euro 5. 1st-generation 2.5 AT and 3.7 AT 333 hp AWD: Euro 4. 1st-generation 5.6 AT 408 hp RWD: Euro 5; AWD Euro 4. 3.0 AT Euro 5. 1st-generation 2.1 AT, 3.7 AT 333 hp RWD, 3.7 AT 320 hp: eco class not measured.
Weight, dimensions, tank, wheels
Kerb mass is measured from 1680 kg (1st-generation 2.5 AT) to 1971 kg (restyle 5.6 AT 420 hp AWD, 76 L). Restyle 2.5 AT 1765 kg / gross 2275 kg. Restyle 3.7 AT 330 hp RWD 80 L: 1754 / 2271 kg — lightest restyle 3.7. Restyle 3.7 AT 333 hp AWD: 1845 / 2470 kg (heaviest gross in the file). Restyle 5.6 AT 408 hp AWD: 1925 / 2405 kg. Restyle 5.6 AT 420 hp RWD 80 L: 1837 / 2333 kg; AWD 80 L: 1927 / 2395 kg. Restyle 2.1 AT: 1872 / 2405 kg. Restyle 3.5 AT: 1894 / 2400 kg. 1st-generation 3.7 AT 320 hp: 1751 / 2310 kg. Not measured kerb and gross: 1st-generation 2.1 AT, 3.0 AT, 3.5 AT.
kg per hp (where kerb is measured): restyle 5.6 AT 420 hp RWD 80 L 4.37 kg/hp; restyle 5.6 AT 420 hp AWD 80 L 4.59; restyle 5.6 AT 408 hp AWD 4.72; restyle 3.7 AT 330 hp RWD 80 L 5.32; restyle 3.7 AT 333 hp AWD 5.54; restyle 3.7 AT 320 hp 5.71; restyle 3.5 AT 6.19; restyle 2.5 AT 7.99; restyle 2.1 AT 11.01. 1st-generation 2.5 AT 7.57 kg/hp — lighter per hp than the restyle 2.5 AT.
Ground clearance: restyle 2.5 AT 151 mm (highest). Restyle 2.1 AT and 1st-generation 2.1 AT / 3.0 AT: 144 mm (lowest). Most 3.7 AT, 3.5 AT, 5.6 AT: 145 mm. 1st-generation 2.5 AT: 149 mm.
Tank 80 L on most cars. Restyle exceptions 76 L: 3.7 AT 330 hp RWD (5.9 s) and both 5.6 AT 420 hp with that tank. Wheels 245/50 R18 and 245/40 R20 where listed: restyle 3.7 AT 333 hp AWD, 5.6 AT 408 hp AWD, 2.1 AT; 1st-generation 5.6 AT 408 hp AWD. Other versions: wheels not measured.
Front/rear suspension where given: Independent, spring. Front brakes Ventilated disc. Rear brakes restyle: Disc ventilated. 1st-generation 2.1 AT and 3.0 AT rear: Disc. Rear suspension 1st-generation 2.1 AT: not measured.
Which version to choose
Daily distance, lowest measured fuel: restyle 2.1 AT — mixed 4.9 l/100 km, CO2 129 g/km, 400 Nm from 1600 rpm, 8.9 s, 220 km/h, RWD, Euro 5. Versus 2.5 AT you give up 51 hp and 0.3 s, gain 147 Nm and 5.0 l/100 km mixed. Do not use 1st-generation 2.1 AT if you need consumption, mass or eco class: those fields are not measured.
Diesel that still sprints: 1st-generation 3.0 AT only — 238 hp, 550 Nm (same peak torque as 5.6 AT 408 hp), 6.9 s, 250 km/h, mixed 7.5 l/100 km. Versus restyle 2.1 AT: +68 hp, +150 Nm, −2.0 s, +30 km/h, +2.6 l/100 km mixed. It disappeared after restyling.
Pace without a large Gasoline V-shaped 8: restyle 3.5 AT Hybrid — 306 hp, 5.3 s, 250 km/h, mixed 6.2 l/100 km, CO2 145 g/km, 1894 kg. It matches 5.6 AT 408 hp AWD to 100 km/h and uses 6.3 l/100 km less mixed. Versus 1st-generation 3.5 AT (303 hp, 5.5 s, consumption not measured): +3 hp, −0.2 s, and you finally have a mixed figure.
Gasoline 6-cylinder, RWD, best sprint among 3.7 AT: restyle 3.7 AT 330 hp, 80 L, 1754 kg, 5.8 s. The 76 L twin is 41 kg heavier (1795 kg) and 0.1 s slower. Avoid mixing them by tank size.
Same name, more hp, slower if AWD: restyle 3.7 AT 333 hp AWD is 6.3 s and 1845 kg. Versus 330 hp RWD 80 L: +3 hp, +91 kg, +0.5 s, mixed 10.9 versus 11.2. Buy AWD for drive, not for the stopwatch.
3.7 AT 320 hp: 6.2 s, restyle mixed 10.2 versus 10.8 before restyling; restyle kerb 1826 kg versus 1751 kg (+75 kg). Choose restyle for mixed and Euro 5 (235 g/km); choose 1st-generation 3.7 AT 320 hp for lower kerb. Top speed 250 km/h both.
Entry Gasoline: 2.5 AT — 9.2 s, 231 km/h, mixed 9.9, 80 L. Prefer 1st-generation if kerb matters (1680 kg, 149 mm, Euro 4, 222 hp at 4800 rpm). Prefer restyle for Euro 5, 221 hp at 6400 rpm, 151 mm. Compression 10.5 and bore×stroke 85 × 73.3 are measured only on the 1st-generation car; restyle those fields not measured.
Infiniti Q70 V8 / 5.6 AT: restyle 5.6 AT 420 hp RWD is the hp and 0–100 leader (420 hp, 565 Nm, 4.7 s, 4.37 kg/hp). AWD on 420 hp is 90 kg heavier at 80 L (1927 vs 1837 kg) and 0.1 s slower. 5.6 AT 408 hp AWD keeps 250 km/h measured and 18.7 city l/100 km; 420 hp top speed is not measured. 1st-generation 5.6 AT 408 hp RWD is the only pre-restyle RWD V-shaped 8 (5.2 s, mixed 12, Euro 5, engine position not measured).
Reliability of the choice, not of the car: this file has no failure rates. What it does show is completeness. Prefer restyle 2.1 AT, restyle 3.5 AT, and restyle 3.7 AT 320 hp when you need consumption plus CO2. Treat 1st-generation 2.1 AT as a torque/sprint spec only. Identical names must be split by hp, RWD/AWD, tank 80 L vs 76 L, and 5552 vs 5600 cm³.
Short map. Mileage: restyle 2.1 AT. Diesel punch that 2.1 AT does not have: 3.0 AT (1st generation only). Hybrid that runs with the 408 hp 5.6 AT: restyle 3.5 AT. Gasoline 6-cylinder stopwatch: restyle 3.7 AT 330 hp RWD 80 L. AWD 6-cylinder: 3.7 AT 333 hp. V8 stopwatch: restyle 5.6 AT 420 hp RWD. V8 with a stated 250 km/h: 5.6 AT 408 hp. Lightest Q70 in the file: 1st-generation 2.5 AT at 1680 kg.
