The Daihatsu Sirion (M1) 1.0 i 12V 4WD, produced between 1998 and 2005, represents a unique offering within the subcompact hatchback segment. This particular variant, powered by a 989cc inline-three cylinder engine and equipped with a five-speed manual transmission and all-wheel drive, was primarily aimed at the Japanese domestic market (JDM) and select European countries where compact, fuel-efficient vehicles with all-weather capability were in demand. It occupied the entry-level position within the Sirion M1 range, offering a more affordable and practical alternative to the higher-spec models.

Introduction
The Daihatsu Sirion (M1), launched in 1998, was a second-generation model building upon the success of its predecessor, the Charade. The M1 series was designed to appeal to a broad audience seeking a practical and economical city car. The 1.0 i 12V 4WD variant, distinguished by its modest power output and all-wheel-drive system, was particularly popular in regions experiencing inclement weather. It was built on the Daihatsu’s 1HX0 platform, shared with other small Daihatsu and Toyota models. This platform allowed for efficient production and a relatively lightweight vehicle.
Powertrain & Engine Architecture
At the heart of the Sirion 1.0 i 4WD lies the Daihatsu ED-20 engine, a 989cc inline-three cylinder petrol engine. This engine utilizes a multi-point fuel injection system and a double overhead camshaft (DOHC) valvetrain, contributing to its relatively efficient operation. The 12-valve configuration (four valves per cylinder) aids in improved breathing and power delivery. While not a powerhouse, the ED-20 was known for its reliability and ease of maintenance. The five-speed manual transmission was a standard feature, providing drivers with good control over the engine’s limited power. The transmission’s gear ratios were optimized for fuel economy and urban driving, with a relatively short final drive to compensate for the engine’s lack of torque. The all-wheel-drive system was a part-time setup, engaging the rear wheels when traction was needed, enhancing stability on slippery surfaces.
Driving Characteristics
The Sirion 1.0 i 4WD’s driving experience is best described as practical and undemanding. With only 56 horsepower, acceleration is modest, and overtaking requires careful planning. The engine feels strained at higher speeds, and the vehicle is most comfortable cruising at around 55-65 mph. The five-speed manual transmission allows drivers to keep the engine in its optimal power band, but frequent shifting is necessary. The all-wheel-drive system provides noticeable improvements in traction, particularly on loose surfaces like gravel or snow. However, it also adds weight, slightly impacting fuel economy and handling on dry pavement. Compared to the 1.3L variants, the 1.0L felt noticeably slower, but offered superior fuel efficiency. The manual transmission also provided a more engaging driving experience than the optional three-speed automatic available on other Sirion models.
Equipment & Trim Levels
The 1.0 i 4WD trim level was generally considered the base model. Standard equipment typically included power steering, central locking, electric front windows, and an AM/FM radio. Interior upholstery was typically a durable cloth material. Optional extras included air conditioning, alloy wheels, and a more advanced audio system. The dashboard layout was functional and straightforward, prioritizing usability over aesthetics. Safety features were relatively basic for the time, typically including a driver’s airbag and ABS brakes.
Chassis & Braking
The Sirion M1 utilized a McPherson strut front suspension and a coil spring rear suspension. This setup provided a comfortable ride, although it wasn’t particularly sporty. The front brakes were discs, while the rear brakes were drums, a common configuration for vehicles in this price range. The ABS system helped to improve braking performance in emergency situations. The relatively lightweight construction of the vehicle contributed to its nimble handling. Stabilizer bars were present, but relatively thin, reflecting the car’s focus on comfort rather than performance.
Market Reception & Comparison
The Sirion 1.0 i 4WD received mixed reviews. Critics praised its fuel efficiency, practicality, and all-weather capability, but criticized its lack of power and basic interior. Compared to other subcompact hatchbacks of the time, such as the Ford Fiesta or the Renault Clio, the Sirion offered a more affordable price point and a unique all-wheel-drive option. However, it lacked the refinement and performance of its European competitors. The 1.3L Sirion models offered a significant performance upgrade, but at a higher price. The 1.0L model appealed to buyers prioritizing economy and practicality over driving excitement.
Legacy
The Daihatsu Sirion M1 1.0 i 4WD has developed a reputation for reliability and durability. The ED-20 engine is known to be robust and relatively easy to repair. Today, these vehicles are becoming increasingly rare, and well-maintained examples are sought after by enthusiasts and collectors. While not a performance icon, the Sirion 1.0 i 4WD represents a practical and economical choice for those seeking a small, reliable, and all-weather capable vehicle. Its simple design and robust construction ensure that many examples remain on the road today, a testament to Daihatsu’s engineering prowess.
