⚙️ Engine Specifications

Common Engines:

2.2L Duratorq TDCi Diesel (most prevalent for 2012 models), 2.4L Duratorq TDCi Diesel (preceding this, but may be covered for continuity/earlier derivatives). Older models might have 2.5L TD5 or 300Tdi. Specific engine coverage depends on the exact manual compilation.

2.2 Tdci Power:

Approx. 122 PS (90 kW) @ 3500 rpm (Note: Specific power outputs can vary slightly by market and tune).

2.2 Tdci Torque:

Approx. 360 Nm (266 lb-ft) @ 1500-2000 rpm

Fuel Type:

Diesel (Common Rail Direct Injection for 2.2L and 2.4L TDCi).

Injection System:

High-pressure common rail system with electronic fuel injection control.

2.2 Tdci Engine Code:

Likely '224DT' or similar designation for the PSA/Ford 2.2L Duratorq TDCi engine.

🔧 Transmission

Type:

6-speed Manual Transmission (often a variant of the R380 gearbox, or newer equivalent like the LT77 for earlier models but 6-speed is typical for 2012).

Type:

2-speed, lockable, permanent four-wheel drive transfer case (e.g., LT230).

Gear Ratios:

Specific gear ratios for all forward gears and reverse are detailed within the manual, crucial for off-road performance and diagnostics.
