The Westfield 4.0i V8, produced between 1995 and 2001, represents a high-performance variant within the Westfield model range. Built upon the foundational principles of the Westfield marque – lightweight construction and exhilarating driving experience – the 4.0i V8 catered to enthusiasts seeking a raw, unfiltered sports car experience. This model occupied the premium position in the Westfield lineup during its production run, offering significantly more power and performance than the smaller-engined options. It’s a kit car, meaning it was sold in component form for customers to assemble themselves, or purchased fully assembled from Westfield. The 4.0i V8 is based on the Lotus Seven design, a British sports car known for its simplicity and agility.
Westfield 4.0i V8: A Detailed Overview
The Westfield 4.0i V8 was conceived as a response to demand for a more powerful Westfield model. While earlier Westfields offered nimble handling and a fun driving experience, some customers desired a substantial increase in horsepower. The 4.0i V8 delivered this, utilizing a Ford-sourced V8 engine to create a truly potent sports car. The car’s design philosophy remained true to the original Lotus Seven, emphasizing minimal weight and maximum driver engagement. The car was available as a kit or fully built, appealing to a wide range of customers from experienced mechanics to those seeking a turn-key performance vehicle.
Powertrain & Engine Architecture
The heart of the Westfield 4.0i V8 is its 3.951-liter (241.1 cubic inch) V8 engine. This engine is based on the Ford Windsor family of engines, specifically utilizing components from the Ford Explorer and Mustang. The engine produces 200 horsepower at 4750 rpm and 319 Nm (235.28 lb-ft) of torque at 2600 rpm. This translates to a power-to-weight ratio of approximately 3 kg/hp (333.3 hp/tonne), contributing to the car’s impressive acceleration. The engine features a 9.35:1 compression ratio and utilizes a multi-port fuel injection system for efficient fuel delivery. The valvetrain is a double overhead camshaft (DOHC) design, optimizing airflow for increased power output.
The engine is mated to a 5-speed manual transmission, providing precise gear changes and allowing the driver to fully exploit the engine’s power. The drivetrain is rear-wheel drive, further enhancing the car’s sporty handling characteristics. The transmission’s gear ratios are tuned to maximize acceleration, with a focus on delivering strong performance in the lower gears. The engine is naturally aspirated, meaning it does not utilize a turbocharger or supercharger, relying solely on displacement and efficient engine design for its power.
Driving Characteristics
The Westfield 4.0i V8 offers a driving experience that is both exhilarating and demanding. Its lightweight construction (approximately 600 kg or 1322.77 lbs) combined with the potent V8 engine results in blistering acceleration. The car can accelerate from 0 to 60 mph in approximately 4.3 seconds and reach a top speed of 137.94 mph (222 km/h). The car’s handling is exceptionally responsive, thanks to its short wheelbase and well-tuned suspension. The rear-wheel drive configuration provides excellent traction and allows for controlled oversteer, appealing to experienced drivers. However, the car’s lack of driver aids and its raw power require a skilled driver to fully control. The steering is direct and communicative, providing ample feedback to the driver. The overall driving experience is characterized by a visceral connection between the driver and the machine.
Equipment & Trim Levels
As a kit car, the Westfield 4.0i V8 offered a degree of customization not typically found in production vehicles. While a base level of equipment was standard, customers could specify a wide range of options to tailor the car to their individual preferences. Standard features typically included basic instrumentation (speedometer, tachometer, fuel gauge), bucket seats, and a simple interior layout. Optional extras included upgraded suspension components, performance brakes, leather upholstery, and a roll cage for track use. The dashboard configuration was minimalist, reflecting the car’s focus on driving performance. The car’s interior was spartan but functional, prioritizing weight savings over luxury. The exterior was typically finished in a bright color, emphasizing the car’s sporty character.
Chassis & Braking
The Westfield 4.0i V8 utilizes a lightweight space frame chassis constructed from steel. This chassis provides a rigid and strong foundation for the car, while minimizing weight. The suspension consists of coil springs and dampers at all four corners, providing a firm but compliant ride. The front and rear suspension are independent, contributing to the car’s excellent handling. The braking system features disc brakes on all four wheels, providing ample stopping power. The brakes are unassisted, requiring a firm pedal effort. The car’s tires are typically 205/50 R15, providing a good balance of grip and performance. The steering system is a rack and pinion type, offering precise and responsive steering.
Market Reception & Comparison
The Westfield 4.0i V8 was generally well-received by automotive enthusiasts and critics. It was praised for its exhilarating performance, responsive handling, and raw driving experience. However, some critics noted that the car’s lack of refinement and its demanding driving characteristics made it unsuitable for casual drivers. Compared to other Westfields, the 4.0i V8 offered a significant performance advantage. Compared to other sports cars in its price range, the Westfield 4.0i V8 offered a unique combination of performance and affordability. Its kit car nature allowed customers to save money on the purchase price, but required them to invest time and effort in assembly. Fuel economy was reasonable for a V8-powered sports car, with figures of 18.1 US mpg (13 l/100 km) in urban conditions and 29.4 US mpg (8 l/100 km) on the open road.
