Pontiac Torrent

Pontiac Torrent: which version to buy (2005–2009)

If you are choosing a Pontiac Torrent rather than reading a first-look overview, the catalogue is simple: one generation (2005-01-01 to 2009-12-31), SUV 5-doors, four Gasoline versions, all Automatic, all Front, transverse, all No boost, all a 63 L tank and 201 mm ground clearance. The buy decision is not “which generation” — there is only 1 generation.

If you are choosing a Pontiac Torrent rather than reading a first-look overview, the catalogue is simple: one generation (2005-01-01 to 2009-12-31), SUV 5-doors, four Gasoline versions, all Automatic, all Front, transverse, all No boost, all a 63 L tank and 201 mm ground clearance. The buy decision is not “which generation” — there is only 1 generation. It is which of the two engines you want, and whether the extra 55 kg of AWD is worth it.

The four catalogue names are 3.4 AT, 3.4 AT, 3.6 AT, and 3.6 AT. Two pairs share a name; they are not the same car. Split them by drive and kerb weight: 3.4 AT at 185 hp / FWD / 1685 kg, 3.4 AT at 185 hp / AWD / 1740 kg, 3.6 AT at 264 hp / FWD / 1685 kg, 3.6 AT at 264 hp / AWD / 1740 kg.

Generations compared: what actually changed

There is nothing to stack generation against generation. Pontiac Torrent 1 generation is the whole production window. Restyling is not a second generation in this data. Every version starts 2005-01-01 and stops 2009-12-31. Chassis numbers that stay the same across all four: Independent, spring front, Independent, spring rear, Disc front brakes, Disc rear brakes, 92 octane fuel, multi-point Distributed injection (multi-point). What you “buy extra” is never a later body — it is engine, gearbox count, and drive.

Engine and specs: the four versions side by side

Power per litre (hp ÷ displacement in litres): 3.4 AT is 185 / 3.350 ≈ 55.2 hp/L. 3.6 AT is 264 / 3.564 ≈ 74.1 hp/L. The larger engine is not a small step: +79 hp (+42.7%) and +54 Nm on only +214 cm³ (+6.4% volume). Compression is 9.5 on 3.4 AT versus 10.2 on 3.6 AT. Bore × stroke is 92 × 84 versus 94 × 85.6. Peak power arrives at 5200 rpm on 3.4 AT and 6300 rpm on 3.6 AT; peak torque arrives earlier on the stronger engine (3200 vs 3800 rpm). Valve count is 2 per cylinder on 3.4 AT and 4 on 3.6 AT. Gear count is 5 versus 6. Those are the mechanical extras the 3.6 AT buys inside the same SUV 5-doors shell.

Performance, mpg, and 0–100: what is measured

3.4 AT FWD: 8.5 s to 100 km/h, top speed 180 km/h. City / highway / combined consumption: not measured. CO₂: not measured. Eco class: not measured.

3.4 AT AWD: 0–100 not measured. Top speed 180 km/h (same figure as the FWD 3.4 AT). Consumption, CO₂, eco class: not measured.

3.6 AT FWD: 6.9 s to 100 km/h — 1.6 s quicker than the measured 3.4 AT FWD. Top speed not measured. Consumption, CO₂, eco class: not measured.

3.6 AT AWD: 6.9 s to 100 km/h (same measured sprint as FWD 3.6 AT). Top speed not measured. Consumption, CO₂, eco class: not measured.

You cannot pick a Torrent on mpg from this catalogue: every consumption cell is not measured. You can pick on sprint only where a number exists. The only 0–100 pair that is fully measured on both engines in FWD form is 8.5 vs 6.9. The AWD 3.4 AT has no 0–100 figure, so do not invent a handicap from the extra 55 kg.

Dimensions, weight, tank, wheels

Kerb weight is the only mass that splits the range: 1685 kg on both FWD cars (3.4 AT and 3.6 AT), 1740 kg on both AWD cars. Gross weight: not measured on all four. Ground clearance 201 mm on all four. Tank 63 L on all four. Wheel sizes: not measured on all four.

Weight per horsepower:

• 3.4 AT FWD: 1685 / 185 ≈ 9.11 kg/hp
• 3.4 AT AWD: 1740 / 185 ≈ 9.41 kg/hp
• 3.6 AT FWD: 1685 / 264 ≈ 6.38 kg/hp
• 3.6 AT AWD: 1740 / 264 ≈ 6.59 kg/hp

AWD adds 55 kg (+3.3% on the 1685 kg FWD kerb). On the 185 hp 3.4 AT that is +0.30 kg/hp. On the 264 hp 3.6 AT it is +0.21 kg/hp. The same 55 kg is a smaller load on the stronger engine.

Which version to buy

Buy 3.4 AT FWD (185 hp) if you want the lightest 3.4 AT, the only 3.4 AT with a measured 0–100 (8.5 s), and FWD. You get 5 gears, 2 valves per cylinder, 285 Nm, 3350 cm³, 1685 kg. You do not get AWD. You do not get the 264 hp engine. Fuel use is not measured, so “cheaper to run” is not a number in this data.

Buy 3.4 AT AWD (185 hp) if AWD is the requirement and you stay on the 185 hp engine. Same 285 Nm, same 5-speed Automatic, same 180 km/h top speed as FWD 3.4 AT. You pay 55 kg. 0–100 is not measured on this version, so you cannot claim it is slower than FWD from a sprint figure — only from mass. This is the heaviest-per-horsepower Torrent in the table (≈ 9.41 kg/hp).

Buy 3.6 AT FWD (264 hp) if the decision is performance inside the same 1685 kg FWD kerb as the weaker FWD car. You gain 79 hp, 54 Nm, a 6-speed Automatic, 4 valves per cylinder, ≈ 18.9 extra hp per litre, and a measured 6.9 s 0–100 (1.6 s less than FWD 3.4 AT). Top speed is not measured on 3.6 AT, so you cannot say it is faster than the 180 km/h of 3.4 AT — only quicker to 100. This is the best kg/hp in the range (≈ 6.38).

Buy 3.6 AT AWD (264 hp) if you want AWD without giving up the 264 hp engine. Same 6.9 s 0–100 as FWD 3.6 AT in this data, same 339 Nm, 1740 kg. Versus 3.4 AT AWD you still gain 79 hp on the same 1740 kg (≈ 6.59 vs ≈ 9.41 kg/hp). Versus FWD 3.6 AT you add 55 kg and AWD; the sprint number does not change in the catalogue.

What extra money cannot be priced here. There are no prices in the data. The “extra” is arithmetic only: AWD = +55 kg, same 201 mm clearance, same 63 L tank. The engine step = +79 hp, +54 Nm, +1 gear, +2 valves per cylinder, +214 cm³, +0.7 compression, −1.6 s 0–100 on the two FWD cars that both have a sprint figure.

Reliability / problems. No failure rates, recalls, or service intervals are in this dataset. Those searches cannot be answered from these numbers.

Short rule: one generation, four versions. If you need AWD, choose between the two 1740 kg cars — 3.4 AT at 185 hp or 3.6 AT at 264 hp. If you do not need AWD, the FWD pair shares 1685 kg; the measured gap is 8.5 s versus 6.9 s. If mpg is the reason you opened the page, every version is not measured — do not pick a Torrent on consumption from this catalogue.
