Rezvani Tank: generations: what actually changed

What 2 generation adds is not a new body: same SUV 5-doors, same AWD, same 257 mm. It adds the 2987 cm³ Diesel pair, three Manual boxes, two extra Automatic ratios (8 instead of 6), and 297 hp more on 6.2 AT (1014 versus 717). What it does not add in the measured columns: 0–100 and top speed are measured only on two 1 generation cars; they are not measured on any 2 generation version.

1 generation ran from 2017-01-01 to 2019-12-31 with three versions, all Automatic with 6 gears: 3.6 AT, 6.2 AT, 6.4 AT. Fuel tank 85 litres. No diesel and no Manual in this generation.

2 generation starts 2019-01-01 (stop not measured) with seven versions. The tank is 81 litres — 4 litres smaller than 1 generation. Gearboxes split: Automatic with 8 gears on 3.0 AT, 3.6 AT, 6.2 AT, 6.4 AT; Manual with 6 gears on 3.0 MT, 3.6 MT, 6.4 MT. Diesel appears only here: 3.0 AT and 3.0 MT.

Power per litre (hp ÷ displacement in litres):

The 6.2 AT jump between generations is 297 hp (41% more) at the same 6166 cm³, same 8 cylinders V-shaped, same Turbo, same Direct injection (direct), same Front, longitudinal layout. Compression on 1 generation 6.2 AT is 9.5; on 2 generation 6.2 AT compression is not measured. Bore × stroke on 1 generation 6.2 AT is 103.9 × 90.9; on 2 generation 6.2 AT it is not measured.

3.0 AT and 3.6 AT in 2 generation share 285 hp at 6400 rpm and 210 kW. The diesel is 617 cm³ smaller (2987 vs 3604). Torque on 3.6 AT / 3.6 MT is 350 Nm at 4800 rpm; on both diesels torque is not measured. Compression: diesel 15.5 versus gasoline 11.3. Bore × stroke: diesel 83 × 92, gasoline 96 × 83. Diesel feed system is not measured; gasoline uses Distributed injection (multi-point). Both sit Front, transverse.

6.4 AT / 6.4 MT make 215 hp more than 3.6 AT / 3.6 MT (500 vs 285) and 287 Nm more (637 vs 350). Displacement is 2813 cm³ larger (6417 vs 3604). Peak torque arrives 500 rpm earlier (4300 vs 4800). Compression is 10.9 versus 11.3. Layout moves to Front, longitudinal with 8 cylinders V-shaped and 2 valves per cylinder instead of 6 / 4.

6.2 AT 2 generation (1014 hp) versus 6.4 AT (500 hp): 514 hp more from 251 cm³ less (6166 vs 6417). Versus 3.6 AT (285 hp): 729 hp more. Versus the diesels (285 hp): the same 729 hp gap. Torque on 2 generation 6.2 AT is not measured, so it cannot be ranked against 881 Nm on 1 generation 6.2 AT or 637 Nm on 6.4 AT.

Performance and mpg

Measured 0–100 and top speed exist only on two 1 generation versions:

The 6.2 AT is 4.4 s quicker and 75 km/h faster than the 3.6 AT in the same generation. 6.4 AT 1 generation: 0–100 not measured, top speed not measured.

Every 2 generation version: 0–100 not measured, top speed not measured. City / highway / combined consumption: not measured on all ten versions. CO₂: not measured. Eco class: not measured. MPG and gas mileage cannot be compared from this catalogue; the gap is the same for diesel and 95.

Fuel type is the only economy-adjacent fact that is measured: Diesel on 3.0 AT and 3.0 MT; 95 on every other version.

Dimensions, weight, tank, wheels

Ground clearance is 257 mm on every version in both generations — no size comparison between engines on that axis.

Kerb weight is measured only on the 3604 cm³ gasoline sixes: 1950 kg for 3.6 AT and 3.6 MT in 2 generation, and 1950 kg for 3.6 AT in 1 generation. Gross weight: not measured on any version. Wheel size: not measured on any version. Length and other exterior dimensions: not measured.

Weight per horsepower where both numbers exist: 1950 / 285 ≈ 6.84 kg/hp on those 3.6 versions. For 3.0 AT, 3.0 MT, 6.2 AT, 6.4 AT, 6.4 MT, kerb weight is not measured, so kg/hp is not measured.

Fuel capacity: 85 litres in 1 generation, 81 litres in 2 generation (4 litres, about 4.7%, less). That is the only tank change in the data.

Front suspension is Independent, spring on all versions. Rear suspension is Independent, spring only on 2 generation 3.0 AT and 3.0 MT; on every other version rear suspension is not measured. Front brakes are Ventilated disc on all. Rear brakes: Disc ventilated on the two diesels; Disc on every gasoline version.

Which version to choose

Buy 2 generation 3.0 AT or 3.0 MT if the brief is the smallest engine at 285 hp. Both are 2987 cm³ Diesel, 6 cylinders V-shaped, 4 valves per cylinder, Turbo, Front, transverse, 285 hp / 210 kW at 6400 rpm, AWD, tank 81 litres, clearance 257 mm. The only measured difference between them is the box: Automatic / 8 versus Manual / 6. Torque, 0–100, top speed, mpg, and kerb weight are not measured on either, so they cannot be ranked on those axes. Specific output ≈ 95.4 hp/l is the highest of the 285 hp group.

Buy 2 generation 3.6 AT or 3.6 MT (or 1 generation 3.6 AT) if you want 285 hp on 95 with measured torque. All three are 3604 cm³, 285 hp / 210 kW at 6400, 350 Nm at 4800, 6 cylinders V-shaped, 4 valves, Distributed injection (multi-point), compression 11.3, bore × stroke 96 × 83, Front, transverse, kerb 1950 kg. 2 generation 3.6 AT is Automatic / 8; 1 generation 3.6 AT is Automatic / 6; 3.6 MT is Manual / 6. The extra two gears are the only gearbox change between the two 3.6 AT cars. 1 generation 3.6 AT is the only 285 hp version with measured 0–100 (8.9 s) and top speed (185 km/h); 2 generation 3.6 AT / 3.6 MT do not have those figures. Tank 85 vs 81 litres is the other generation split. Versus the diesels at the same 285 hp, you pay 617 cm³ extra displacement and lose the Turbo label (boost not measured on 3.6); you gain 350 Nm (diesels: torque not measured) and a measured kerb weight.

Buy 6.4 AT or 6.4 MT if 500 hp and 637 Nm are the target, not the catalogue peak. Displacement 6417 cm³, 8 cylinders V-shaped, 2 valves per cylinder, Distributed injection (multi-point), compression 10.9, 95, Front, longitudinal, AWD. 2 generation offers both 6.4 AT (Automatic / 8) and 6.4 MT (Manual / 6); 1 generation offers only 6.4 AT (Automatic / 6). Power and torque do not change across those three names. Versus 3.6 AT: +215 hp, +287 Nm, +2813 cm³, layout Front, longitudinal instead of Front, transverse. Versus 2 generation 6.2 AT: 514 hp less from a larger engine — 6.4 is not the power leader. 0–100, top speed, mpg, kerb weight: not measured on any 6.4. Bore × stroke is 103.9 × 94.5 on 2 generation 6.4 AT / 6.4 MT; 1 generation 6.4 AT lists 103 (stroke not measured in that field).

Buy 1 generation 6.2 AT if you need the only 6.2 with a full performance sheet. 717 hp / 527 kW at 6000, 881 Nm at 4000, 6166 cm³, Turbo, Direct injection (direct), compression 9.5, bore × stroke 103.9 × 90.9, Automatic / 6, AWD, 0–100 4.5 s, top speed 260 km/h, tank 85 litres. That is 432 hp and 531 Nm above 3.6 AT, and 4.4 s / 75 km/h above it. Versus 6.4 AT in the same generation: +217 hp and +244 Nm from 251 cm³ less. Kerb weight not measured.

Buy 2 generation 6.2 AT if the only number that matters is peak horsepower. 1014 hp / 746 kW at 6000 is 297 hp above the 1 generation 6.2 AT and 514 hp above 6.4 AT. Same 6166 cm³, same Turbo, same Direct injection (direct), Automatic now with 8 gears instead of 6, tank 81 litres. Torque, 0–100, top speed, compression, bore × stroke, mpg, and kerb weight are not measured — so this version cannot be shown to be quicker than the 4.5 s / 260 km/h 1 generation 6.2 AT; only the horsepower column is larger.

What the extra displacement buys, in arithmetic only. Stepping from 2987 to 3604 cm³ at 285 hp does not buy horsepower; it buys 95 instead of Diesel, 350 Nm (if you accept that the diesel torque is not measured), and 1950 kg on the scale. Stepping from 3604 to 6417 cm³ buys 215 hp and 287 Nm. Stepping from 6417 to 6166 cm³ on 2 generation 6.2 AT buys 514 hp while shrinking the engine — the extra output is not from more litres, it is from the Turbo 1014 hp tune. There are no prices in this dataset, so “extra money” cannot be stated; the extra hardware that is measured is litres, gears (6 vs 8), Manual vs Automatic, Diesel vs 95, and the 297 hp generation gap on 6.2 AT.

Reliability / problems: not measured in this catalogue. Interior, seating, military editions, and whether a given car is street-legal are not in the data and are not used here.

Short map. Same 285 hp, want diesel and a choice of Automatic or Manual: 3.0 AT or 3.0 MT (2 generation only). Same 285 hp, want 95 and 350 Nm: 3.6 AT or 3.6 MT; pick 1 generation 3.6 AT if 8.9 s / 185 km/h must be on the sheet. Want 500 hp / 637 Nm and a Manual: 6.4 MT. Want 500 hp without a clutch: 6.4 AT (8 gears in 2 generation, 6 in 1 generation). Want measured 4.5 s and 260 km/h: 1 generation 6.2 AT (717 hp). Want the highest hp in the file: 2 generation 6.2 AT (1014 hp), knowing that its sprint, top speed, torque, and weight are not measured.
