The first generation Ford Focus, affectionately known as the Mk1, arrived in October 1998, revolutionising the family car segment and scooping the coveted Car of the Year award in 1999. Replacing the venerable Escort, the Focus presented a radical departure with its distinctive 'New Edge' styling and a sophisticated, fully independent 'Control Blade' rear suspension system that set new benchmarks for ride and handling. Available in a variety of body styles including three- and five-door hatchbacks, a four-door saloon, and a practical five-door estate, the Mk1 Focus was also lauded for its comprehensive standard safety and security features. These included essential driver and passenger airbags, side impact bars within the doors, anti-submarining seats to prevent occupants from sliding under the seatbelts in a crash, and an advanced seatbelt system featuring pre-tensioners and load limiters. Security was also a priority, with a standard engine immobiliser, protected locks, a key-operated bonnet release, and a security-coded audio system. Most models also benefited from double-locking doors for enhanced peace of mind.
Petrol Power: The Zetec and Zetec-SE Engine Range
At the heart of the Mk1 Focus's impressive performance and refinement lay its range of 16-valve, four-cylinder petrol engines, specifically the Zetec and Zetec-SE units. These engines, derived from proven Ford powertrains previously found in models like the Fiesta and Mondeo, were offered in a variety of capacities to cater to different driving preferences and needs. The available engine sizes were: 1.4-litre, 1.6-litre, 1.8-litre, and 2.0-litre.
What set these engines apart for their era was their sophisticated engine management system. This system integrated multi-point sequential fuel injection, ensuring precise fuel delivery to each cylinder for optimal combustion, and a distributorless ignition system, which enhances reliability and performance. Furthermore, these engines were equipped with advanced emissions control technologies. This included evaporative emissions control to prevent fuel vapours from escaping into the atmosphere, exhaust gas recirculation (EGR) to reduce NOx emissions, and a three-way regulated catalytic converter to treat exhaust gases before they exit the tailpipe. These measures were crucial for complying with the increasingly stringent emissions standards of the late 1990s and early 2000s, while simultaneously delivering the responsive performance and competitive fuel economy that buyers expected from a modern family car.
Key Features of Zetec/Zetec-SE Engines:
- 16-valve, four-cylinder design
- Capacities: 1.4L, 1.6L, 1.8L, 2.0L
- Multi-point sequential fuel injection
- Distributorless ignition
- Advanced emissions control systems (EGR, catalytic converter)
- Good balance of performance and fuel economy
Diesel Dynamism: The Endura-DI Engine
For those prioritising fuel efficiency and lower running costs, Ford offered the Endura-DI turbodiesel engine. While based on an earlier engine unit that had seen service in the Mondeo, the Endura-DI featured such a significant number of revisions and technological enhancements that it was practically a new engine in its own right. It represented a 'state of the art' unit for its time in the diesel segment.
The Endura-DI was a direct injection diesel engine, meaning fuel was injected directly into the combustion chamber under high pressure. This design contributes to greater efficiency and power output compared to older indirect injection systems. Crucially, it featured an electronically controlled injection pump, allowing for more precise management of fuel delivery according to engine load and speed. Complementing this was an engine management system that was very similar in its sophistication to those found in the petrol-engined models. This integrated approach ensured that the Endura-DI offered a compelling blend of strong performance, excellent fuel economy, and importantly, low emissions, making it an attractive option for budget-conscious and environmentally aware drivers.
Key Features of the Endura-DI Engine:
- Turbodiesel with Direct Injection
- Electronically controlled injection pump
- Sophisticated engine management system
- Emphasis on fuel economy and low emissions
- Strong torque for everyday driving
Transmission Options: Manual and Automatic
The Mk1 Ford Focus featured a transversely mounted engine configuration, driving the front wheels. Buyers had a choice between two main transmission types:
Five-Speed Manual Transmission: This provided the traditional, engaging driving experience that many enthusiasts prefer. It featured a hydraulically operated clutch, offering a smooth and progressive engagement.
Four-Speed Automatic Transmission: For those seeking added convenience, particularly in urban driving conditions, an electronically controlled four-speed automatic transmission was available. However, it's important to note that this automatic gearbox was exclusively offered with the 1.6-litre petrol engines.
| Engine Type | Manual Transmission | Automatic Transmission |
|---|---|---|
| Zetec/Zetec-SE Petrol (1.4L, 1.8L, 2.0L) | Yes | No |
| Zetec-SE Petrol (1.6L) | Yes | Yes |
| Endura-DI Turbodiesel | Yes | No |
Chassis and Handling: A Focus on Driving Dynamics
The Mk1 Focus's reputation for exceptional handling was largely down to its advanced suspension system. At the front, it employed MacPherson struts combined with transverse lower arms, a proven and effective setup for precise steering control and good road holding. However, the real innovation lay at the rear. Ford fitted its unique 'Control Blade' independent suspension, a system cleverly derived from the design used in the Mondeo Estate. This sophisticated rear suspension contributed significantly to the car's stable and composed ride, especially over uneven surfaces and during spirited driving.
Anti-roll bars were fitted at both the front and rear axles to further minimise body roll during cornering, keeping the car flat and predictable. The braking system typically consisted of disc brakes at the front and drum brakes at the rear on most models, offering adequate stopping power for everyday use. However, higher-specification models or optional upgrades included front and rear disc brakes, along with an electronically controlled Anti-lock Braking System (ABS). For those seeking even greater control, a Traction Control System (TCS) was also available as an option, typically paired with models equipped with ABS.
The steering was power-assisted, with the pump driven by a belt from the engine, ensuring lighter steering effort at low speeds. The rack-and-pinion steering gear was mounted behind the engine. A subtle yet significant design feature was the passive rear-wheel steering geometry incorporated into the rear suspension. This system subtly adjusted the rear wheels under load, such as during heavy cornering or rapid lane changes, to aid stability and agility. Furthermore, models fitted with ABS could optionally be equipped with the Electronic Stability Program (ESP). This advanced system acted as a safety net, detecting when the car was starting to slide (either the front or rear end) and could selectively apply the brakes to individual wheels to help regain control and steer the vehicle back onto its intended path.
