Infiniti EX

Infiniti EX: which version to buy

If you are choosing an Infiniti EX rather than reading about the nameplate in general, the catalogue has one generation (2007–2013), one body (SUV 5-doors), and eight versions whose names must stay as in the data: 2.5 AT, four distinct 3.5 AT rows, two 3.7 AT rows, and 3.0 AT.

If you are choosing an Infiniti EX rather than reading about the nameplate in general, the catalogue has one generation (2007–2013), one body (SUV 5-doors), and eight versions whose names must stay as in the data: 2.5 AT, four distinct 3.5 AT rows, two 3.7 AT rows, and 3.0 AT. The buying question is arithmetic: how much extra power, how much extra mass, how much extra fuel, and which fields are not measured.

People looking up Infiniti EX35, EX37, 2008–2013 Infiniti EX35 specs, horsepower, engine size, mpg, and dimensions are comparing these same eight rows. There is no second generation to jump to, so the choice is only among these versions.

Generations: one production window, eight versions

1 generation ran from 2007-01-01 to 2013-12-31 as SUV 5-doors with 8 versions. Restyling is not a separate generation in this data. Year-coded searches (2008 Infiniti EX35 specs, 2009, 2010, 2011, 2012, 2013 Infiniti EX35 horsepower) all point at this same window; the data does not split those calendar years into different generations.

What changed between versions is displacement, output, gearbox step count, drive, fuel, boost, mass, clearance, and which numbers were measured — not a new generation.

Infiniti EX engine and specs table

Exact names as in the database. Two 3.5 AT and two 3.7 AT rows are distinguished by horsepower (and, where it differs, by gearbox, drive, or Euro class). Layout and fuel labels are the English tags from the data.

Engine placement on every version: Front, longitudinal. Valves per cylinder: 4. Gasoline versions use Distributed injection (multi-point); 3.0 AT fuel system is not measured. Fuel grade: 95 on all Gasoline rows; Diesel on 3.0 AT.

Infiniti EX35 engine size in this set is 3498 cc or 3500 cc depending on the 3.5 AT row. Infiniti EX37 size is 3696 cc on both 3.7 AT rows. 2.5 AT is 2496 cc. 3.0 AT is 2993 cc.

Horsepower, power per litre, and what the extra displacement buys

2.5 AT is the lowest Gasoline output: 222 hp (163 kW) at 6400 rpm, 252 Nm at 4800 rpm. That is 222 / 2.496 ≈ 89.0 hp per litre — among the densest Gasoline figures here.

The four 3.5 AT rows are the Infiniti EX35 cluster:

• 3.5 AT 302 hp / 3498 cc: 302 − 222 = 80 hp more than 2.5 AT, 341 − 252 = 89 Nm more. Power per litre: 302 / 3.498 ≈ 86.3 hp/L.
• 3.5 AT 295 hp RWD and 3.5 AT 295 hp AWD: 295 hp, 366 Nm, 3500 cc. Versus the 302 hp / 3498 cc row: 7 hp less, but 366 − 341 = 25 Nm more. Power per litre: 295 / 3.500 ≈ 84.3 hp/L.
• 3.5 AT 302 hp / 3500 cc / 7 gears: same 302 hp as the 3498 cc five-speed, torque not measured, 3500 − 3498 = 2 cc larger in the data.

The two 3.7 AT rows are the Infiniti EX37 cluster:

• 3.7 AT 330 hp: 330 hp at 7000 rpm, 361 Nm at 5200 rpm, 3696 cc. Versus 2.5 AT: +108 hp, +109 Nm. Versus 3.5 AT 302 hp: +28 hp, and 361 − 341 = 20 Nm more than the 3498 cc five-speed. Power per litre: 330 / 3.696 ≈ 89.3 hp/L — the highest Gasoline density here.
• 3.7 AT 320 hp: 320 hp at 7000 rpm, 360 Nm at 5200 rpm, same 3696 cc. Versus the 330 hp 3.7 AT: 10 hp and 1 Nm less. Power per litre: 320 / 3.696 ≈ 86.6 hp/L. Euro 5 on this row versus Euro 4 on the 330 hp 3.7 AT.

3.0 AT (Diesel, Turbo): 238 hp at 3750 rpm, 550 Nm at 1750 rpm, 2993 cc. Versus 2.5 AT: +16 hp, +298 Nm. Versus 3.5 AT 302 hp: 64 hp less, but 550 − 341 = 209 Nm more. Power per litre: 238 / 2.993 ≈ 79.5 hp/L — lowest density, highest torque.

Compression ratio (only where measured): 2.5 AT 10.3; 3.5 AT 302 hp / 3498 cc 10.5; both 3.7 AT 11; all other versions not measured. Bore × stroke: 2.5 AT 85 × 73.3; 3.5 AT 302 hp / 3498 cc 95.5 × 81.4; both 3.7 AT 95.5 × 86; remaining versions not measured.

Performance and economy (mpg / L/100 km)

0–100 km/h and top speed:

• 2.5 AT: 9.4 s, 210 km/h — slowest and lowest top speed among measured Gasoline rows.
• 3.5 AT 302 hp / 3498 cc, 3.5 AT 295 hp AWD, 3.5 AT 302 hp / 3500 cc 7 gears: 6.9 s, 231 km/h. 9.4 − 6.9 = 2.5 s quicker than 2.5 AT; 231 − 210 = 21 km/h more top speed.
• 3.5 AT 295 hp RWD: 0–100 not measured, top speed not measured.
• Both 3.7 AT: 6.4 s, 240 km/h. 6.9 − 6.4 = 0.5 s quicker than the measured 3.5 AT rows; 240 − 231 = 9 km/h more. Versus 2.5 AT: 3.0 s quicker, 30 km/h more.
• 3.0 AT: 7.9 s, 221 km/h. Faster than 2.5 AT by 9.4 − 7.9 = 1.5 s and 11 km/h; slower than measured 3.5 AT by 7.9 − 6.9 = 1.0 s.

Fuel consumption (L/100 km), city / highway / mixed — the mpg-style question in this catalogue:

• 2.5 AT: 14.3 / 8.4 / 10.6.
• 3.5 AT 302 hp / 3498 cc, 3.5 AT 295 hp AWD, 3.5 AT 302 hp 7 gears: 15.9 / 10.2 / 12.3. Mixed is 12.3 − 10.6 = 1.7 L/100 km higher than 2.5 AT. City is 1.6 higher; highway 1.8 higher.
• Both 3.7 AT: 15.7 / 10 / 12.1. Mixed is 0.2 L/100 km lower than the 12.3 3.5 AT rows, 1.5 higher than 2.5 AT.
• 3.0 AT: 10.8 / 7.2 / 8.5. Mixed is 10.6 − 8.5 = 2.1 L/100 km below 2.5 AT, 12.3 − 8.5 = 3.8 below the 12.3 3.5 AT rows, 12.1 − 8.5 = 3.6 below 3.7 AT. City versus 3.5 AT: 15.9 − 10.8 = 5.1 L/100 km.
• 3.5 AT 295 hp RWD: city, highway, mixed all not measured.

CO2: 2.5 AT, 3.5 AT 302 hp / 3498 cc, and 3.7 AT 330 hp are 265 g; the other five versions not measured. Euro class: Euro 4 on 2.5 AT, the 3498 cc 3.5 AT, the 295 hp AWD 3.5 AT, the 7-gear 302 hp 3.5 AT, and 3.7 AT 330 hp; Euro 5 on 3.0 AT and 3.7 AT 320 hp; 3.5 AT 295 hp RWD Euro class not measured.

Dimensions, weight, tank, wheels, ground clearance

Wheel sizes: not measured on all eight versions — Infiniti EX35 wheel specs are not in this dataset.

Fuel tank: 80 L on every version.

Ground clearance:

• 2.5 AT: 147 mm.
• 3.5 AT 302 hp / 3498 cc, 3.5 AT 295 hp AWD, 3.5 AT 302 hp 7 gears, both 3.7 AT: 149 mm (2 mm more than 2.5 AT).
• 3.0 AT: 132 mm — 149 − 132 = 17 mm lower than the 149 mm Gasoline rows, 147 − 132 = 15 mm lower than 2.5 AT.
• 3.5 AT 295 hp RWD: not measured.

Kerb / gross (kg) and kg per horsepower (kerb ÷ hp, where kerb is measured):

• 2.5 AT: 1842 / 2272. 1842 / 222 ≈ 8.30 kg/hp. Payload 2272 − 1842 = 430 kg.
• 3.5 AT 302 hp / 3498 cc: 1905 / 1932. 1905 / 302 ≈ 6.31 kg/hp. Gross is only 1932 − 1905 = 27 kg above kerb in this row — that is the catalogue figure, not a rewritten payload story.
• 3.5 AT 295 hp AWD: 1932 kerb, gross not measured. 1932 / 295 ≈ 6.55 kg/hp. 90 kg heavier than 2.5 AT, 27 kg heavier than the 1905 kg 3.5 AT.
• 3.5 AT 302 hp 7 gears: 1932 kerb, gross not measured. 1932 / 302 ≈ 6.40 kg/hp.
• 3.5 AT 295 hp RWD: kerb not measured, gross not measured.
• Both 3.7 AT: 1870 / 2300. 1870 / 330 ≈ 5.67 kg/hp (330 hp row); 1870 / 320 ≈ 5.84 kg/hp (320 hp row). Lightest Gasoline kerb after 2.5 AT, but 28 kg more than 2.5 AT; payload 2300 − 1870 = 430 kg, same arithmetic as 2.5 AT. Versus the 1932 kg 3.5 AT rows: 1932 − 1870 = 62 kg lighter.
• 3.0 AT: 1985 kerb, gross not measured. 1985 / 238 ≈ 8.34 kg/hp — heaviest kerb and, with 2.5 AT, the highest kg/hp. 1985 − 1842 = 143 kg more than 2.5 AT; 1985 − 1870 = 115 kg more than 3.7 AT.

Suspension: Independent, spring front on all eight; Independent, spring rear on seven; 3.5 AT 302 hp 7 gears rear suspension not measured. Front brakes: Ventilated disc on all. Rear brakes: Disc on 2.5 AT, 3.5 AT 302 hp / 3498 cc, and 3.0 AT; Disc ventilated on 3.5 AT 295 hp RWD, 3.5 AT 295 hp AWD, 3.5 AT 302 hp 7 gears, and both 3.7 AT.

Exterior length/width/height are not measured in this data (Infiniti EX dimensions searches will not find millimetres here).

Which version to choose

There is no price in this dataset, so “extra money” is extra displacement, extra hp, extra gears, AWD versus RWD, Gasoline versus Diesel — judged only by the numbers.

Choose 2.5 AT if the measured mix of 10.6 L/100 km, 7-speed Automatic, AWD, 1842 kg, Euro 4, and 222 hp is enough. You give up 2.5 s to the 6.9 s 3.5 AT cluster and 3.0 s to both 3.7 AT. You keep the smallest Gasoline engine (2496 cc) and the lowest measured Gasoline mixed consumption.

Choose a 3.5 AT (Infiniti EX35) if 6.9 s and 231 km/h are the target and 12.3 L/100 km mixed is acceptable. Then pick among four namesakes:

• 3.5 AT 302 hp / 3498 cc / 5 gears / AWD: torque 341 Nm is measured; kerb 1905 kg is the lightest measured 3.5 AT; Euro 4; CO2 265. Best documented 302 hp EX35 row.
• 3.5 AT 295 hp AWD: same 6.9 s and 12.3 mixed as the 302 hp five-speed, 25 Nm more torque (366 vs 341), 7 hp less, 27 kg heavier than 1905 kg. Buy this row for torque, not peak hp.
• 3.5 AT 302 hp / 3500 cc / 7 gears / AWD: same 302 hp and 6.9 s as the five-speed 3498 cc row, but two more gears and torque not measured. The 7-speed is the reason to take this row over the five-speed 302 hp 3.5 AT — not a measured torque gain.
• 3.5 AT 295 hp RWD: the only RWD EX. 366 Nm, 5 gears, 3500 cc. Acceleration, top speed, consumption, mass, clearance, CO2, Euro class are not measured. Take it only if RWD is the requirement; you cannot compare its 0–100 or mpg to the AWD twins using this catalogue.

Choose 3.7 AT (Infiniti EX37) if 6.4 s and 240 km/h matter more than the 0.2 L/100 km mixed difference versus 3.5 AT (12.1 vs 12.3). Both 3.7 AT rows share 3696 cc, 7-speed Automatic, AWD, 1870/2300 kg, 149 mm, 15.7/10/12.1. Split:

• 3.7 AT 330 hp: highest hp, Euro 4, CO2 265, 5.67 kg/hp.
• 3.7 AT 320 hp: 10 hp less, Euro 5. Same consumption and 0–100 as the 330 hp row. Take Euro 5 over 10 hp if that is the filter.

Versus 2.5 AT, either 3.7 AT is 108 hp or 98 hp stronger (330 or 320 minus 222) at 1.5 L/100 km more mixed fuel.

Choose 3.0 AT if 550 Nm, Turbo Diesel, Euro 5, and 8.5 L/100 km mixed outweigh 238 hp, 7.9 s, 1985 kg, and 132 mm clearance. It is the only Turbo and the only Diesel. Mixed economy is the best measured figure; torque is 550 − 361 = 189 Nm above the 330 hp 3.7 AT. Ground clearance is the lowest measured. kg/hp is almost the same as 2.5 AT (8.34 vs 8.30) because mass rose with torque.

Reliability, oil capacity, air filter, engine bay, extended warranty: not in this dataset — treat them as not measured, not as implied by hp or Euro class.

Short map: lowest Gasoline fuel and hp → 2.5 AT. Documented 302 hp EX35 with measured torque → 3.5 AT 302 hp / 3498 cc. Same sprint, more torque, less hp → 3.5 AT 295 hp AWD. Same 302 hp with 7 gears, torque unknown → 3.5 AT 302 hp 7 gears. RWD only → 3.5 AT 295 hp RWD, with most dynamics not measured. Fastest measured sprint → either 3.7 AT; 330 hp / Euro 4 versus 320 hp / Euro 5. Lowest mixed L/100 km and peak torque → 3.0 AT.
