1Kr-Fe Engine Notes:

A compact and fuel-efficient 1.0-liter, three-cylinder engine known for its simplicity and good urban performance. Features Daihatsu's VVT-i (Variable Valve Timing with intelligence) for improved efficiency and power delivery.

K3-Ve Engine Notes:

A slightly larger and more powerful 1.3-liter, four-cylinder engine offering enhanced performance and smoother operation compared to the 1.0L, making it suitable for highway driving.

1Kr-Fe Output:

Typically around 69 PS (68 hp; 51 kW) and 93 Nm (69 lb-ft) torque. Specific output may vary slightly by market and year. (Manual will detail exact figures).

K3-Ve Output:

Typically around 87 PS (86 hp; 64 kW) and 120 Nm (89 lb-ft) torque. Specific output may vary slightly by market and year. (Manual will detail exact figures).

Fuel Delivery:

Multi-point Fuel Injection (MPI).

Fuel Type:

Unleaded Gasoline.

🔧 Transmission

Standard Transmission:

5-speed Manual Transmission (M/T).

Optional Transmission:

4-speed Automatic Transmission (A/T) or Continuously Variable Transmission (CVT) depending on market and specific model variant.

Drive Type:

Front-Wheel Drive (FWD). All-Wheel Drive (AWD) was also available on some variants, particularly in Japan (Boon).

Transmission Fluid Type:

Manual transmissions typically require API GL-4 gear oil (e.g., 75W-90). Automatic transmissions require specific ATF (Automatic Transmission Fluid), such as Dexron III or equivalent. Manual specifies exact types and capacities.

📐 Dimensions

Overall Length:

Approximately 3610-3670 mm (142.1-144.5 inches), depending on model variant and bumper design.

Overall Width:

Approximately 1665 mm (65.6 inches).

Overall Height:

Approximately 1550 mm (61.0 inches).

Curb Weight:

Ranges from approximately 900 kg to 1050 kg (1984 lbs to 2315 lbs), depending on engine, transmission, and trim level.

Towing Capacity:

Not designed for towing. The manual will not contain towing specifications.

Passenger Capacity:

Typically seats 4-5 passengers, with a surprisingly spacious cabin for its exterior dimensions, a hallmark of the Daihatsu design philosophy for small cars.

Cargo Volume:

Variable depending on seat configuration, but designed for practicality with foldable rear seats to maximize cargo space for a subcompact.

🛡️ Safety Features

Ncap Rating:

Achieved 4 stars in Euro NCAP for the M300 series (e.g., 2005 assessment), indicating a good level of occupant protection for its class.

Active Safety:

Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) were available on higher trims or as optional equipment. The manual will detail specific availability.

Passive Safety:

Driver and front passenger airbags were standard. Side airbags and curtain airbags were available on higher trim levels. Seatbelt pretensioners and load limiters.

Seatbelts:

3-point seatbelts with pretensioners and force limiters for front occupants. 3-point or 2-point seatbelts for rear occupants depending on seating position and market.
