1.1L Petrol Performance:

Approx. 60 PS (59 bhp; 44 kW) and torque figures around 94 Nm (69 lb-ft). Designed for urban economy.

1.4L Petrol Performance:

Approx. 73 PS (72 bhp; 54 kW) and torque figures around 114 Nm (84 lb-ft). Offered a better balance of performance for mixed driving.

1.4L Hdi Diesel Performance:

Approx. 68 PS (67 bhp; 50 kW) and torque figures around 150 Nm (111 lb-ft). Known for excellent fuel economy.

Fuel System Petrol:

Multi-point fuel injection (MPI), typically Bosch or Siemens electronic fuel injection.

Ignition System:

Electronic ignition with distributorless ignition system (DIS) or coil-on-plug ignition, managed by the engine control unit (ECU).

Common Engine Codes:

TU1JP (1.1L), TU3JP (1.4L Petrol), DV4TD (1.4L HDi diesel).

🔧 Transmission

Standard Transmission:

5-speed manual transmission.

Optional Transmission:

SensoDrive (automated manual transmission) was a notable option on some variants, offering clutchless shifting via paddles or a gear selector.

Transmission Features:

Manual transmissions are robust and straightforward. SensoDrive offers an automatic-like experience with potential for manual control, though it was known for sometimes jerky shifts.

Manual Gear Ratios Typical:

Specific gear ratios vary by engine and transmission type. For a typical 1.4L petrol manual, 1st gear might be around 3.46:1, 5th gear around 0.82:1. Final drive ratio typically around 3.72:1. Consult manual for exact figures for specific models.

📐 Dimensions

Length:

Approximately 3,660 mm (144.1 in)

Width:
