Westfield Westfield 1.8 i 16V (116 Hp)

The Westfield 1.8 i 16V, produced between 1998 and 2001, represents a significant iteration within the Westfield model range. This variant, built upon the lightweight chassis for which Westfield is renowned, offered a compelling blend of performance and affordability, positioning itself as a popular choice for enthusiasts seeking a pure driving experience. It falls within the broader lineage of Westfield sports cars, known for their kit car origins and Lotus Seven-inspired design. The 1.8 i 16V was primarily available as a two-seat, two-door cabriolet, catering to the open-top sports car market.

Powertrain & Engine Architecture

At the heart of the Westfield 1.8 i 16V lies a 1.8-liter inline four-cylinder engine. This engine, often sourced from Ford, is identifiable by its 16-valve cylinder head – hence the “16V” designation. The engine code is typically associated with Ford Zetec variants. The engine produces 116 horsepower at 6250 rpm and 162 Nm (119.49 lb-ft) of torque at 4250 rpm. This output translates to a power-to-weight ratio of 5.2 kg/Hp, contributing to the car’s lively performance. The engine features multi-port fuel injection, a common setup for engines of this era, ensuring efficient fuel delivery and optimized combustion. The valvetrain utilizes a double overhead camshaft (DOHC) configuration, enhancing valve control and contributing to the engine’s higher revving nature.

The Westfield 1.8 i 16V exclusively utilized a 5-speed manual transmission. This transmission was chosen to complement the engine’s characteristics and provide drivers with full control over the power delivery. The gearbox is a standard manual unit, known for its relatively direct feel and durability. The drivetrain is rear-wheel drive, a configuration central to the Westfield’s handling dynamics and sporting character.

Engine Specifications

The 1.8-liter engine boasts a bore of 80.6 mm (3.17 in) and a stroke of 88 mm (3.46 in), resulting in a displacement of 1796 cm3 (109.6 cu. in). The compression ratio is set at 10:1, a typical value for performance-oriented engines of the time. The engine is naturally aspirated, relying solely on atmospheric pressure for induction, contributing to its linear power delivery.

Driving Characteristics

The Westfield 1.8 i 16V delivers a distinctly engaging driving experience. Its lightweight construction – with a kerb weight of approximately 600 kg (1322.77 lbs) – combined with the 116 hp engine, results in brisk acceleration. Zero to 60 mph is achievable in around 6.3 seconds, and 0-100 km/h in 6.6 seconds, with a top speed of 177 km/h (109.98 mph). The rear-wheel-drive layout and relatively short wheelbase contribute to nimble handling and a responsive feel. Compared to potential higher-output variants (had they been offered), the 1.8 i 16V prioritizes accessibility and driver involvement over outright speed. The 5-speed manual transmission allows for precise gear selection, enabling drivers to maximize the engine’s power band. The gear ratios are tuned to provide good acceleration in lower gears and comfortable cruising at higher speeds. While not possessing the raw power of larger displacement engines, the 1.8 i 16V offers a balanced and rewarding driving experience, particularly on winding roads.

Equipment & Trim Levels

The Westfield 1.8 i 16V, being a kit car or completed vehicle from a specialist manufacturer, generally featured a minimalist approach to equipment. Standard features typically included basic instrumentation (speedometer, tachometer, fuel gauge, temperature gauge), sports seats, and a leather-wrapped steering wheel. Interior trim was typically spartan, reflecting the car’s focus on performance. The dashboard layout was functional and driver-focused. Optional extras could include upgraded suspension components, performance exhaust systems, and various aesthetic enhancements. The emphasis was on providing a customizable platform for enthusiasts to tailor the car to their specific preferences. Upholstery options were limited, often consisting of durable cloth or leather. Air conditioning and power windows were generally not available, aligning with the car’s lightweight philosophy.

Chassis & Braking

The Westfield chassis is a space frame construction, typically made from steel, providing a rigid and lightweight platform. The suspension utilizes coil springs all around, offering a balance between comfort and handling. The front suspension is independent, while the rear suspension is typically a live axle setup. Braking is provided by disc brakes on all four wheels, offering adequate stopping power for the car’s performance capabilities. The steering system employs a rack and pinion setup, providing precise and responsive steering feel. The standard tire size is 185/60 R15, mounted on 15-inch wheels. The relatively low weight of the vehicle minimizes the stress on the braking and suspension components, contributing to their durability.

Market Reception & Comparison

The Westfield 1.8 i 16V was generally well-received by automotive enthusiasts and the motoring press. Critics praised its engaging driving dynamics, lightweight construction, and affordability. It was often compared favorably to other small sports cars of the era, such as the Mazda MX-5 (Miata) and Lotus Elise (though the Elise was significantly more expensive). Fuel economy was reasonable, with figures of around 11 l/100 km (21.4 US mpg) in urban conditions and 7 l/100 km (33.6 US mpg) on the open road. Reliability was generally good, benefiting from the use of proven Ford engine and transmission components. However, as with any kit car or specialist vehicle, build quality could vary depending on the assembler. Compared to potential higher-performance Westfield variants, the 1.8 i 16V offered a more accessible entry point into the brand, appealing to a wider range of buyers.

Technical Specifications

Legacy

The Westfield 1.8 i 16V remains a popular choice among enthusiasts in the used car market. Its simple construction, readily available parts, and engaging driving experience contribute to its enduring appeal. The Ford Zetec engine is known for its reliability and relatively low maintenance costs. While some components may require periodic replacement due to age, the overall durability of the powertrain is commendable. The Westfield 1.8 i 16V represents a compelling option for those seeking a classic, lightweight sports car that offers a pure and rewarding driving experience. Its status as a well-regarded kit car or completed vehicle ensures its continued presence on roads and tracks for years to come.
