Ford Focus RS8: A Compact Car with Supercar Ambitions
The Ford Focus RS8 is a testament to the versatility and ingenuity of Ford Racing Performance Parts (FRPP). Unveiled at the 2003 Specialty Equipment Market Association (SEMA) show, this one-off concept car redefined what a compact vehicle could achieve by merging the Focus’s agile platform with the raw power of a V8 engine and a rear-wheel-drive configuration. Designed to showcase the potential of FRPP’s "Cammer" V8 crate engine, the RS8 remains one of the most audacious Focus projects ever created.
The Heart of a Beast
At the core of the Focus RS8 lies the "Cammer" V8, a 5.0-liter all-aluminum engine originally designed for Ford’s racing endeavors. This powerhouse churns out an incredible 420 horsepower at 6,700 rpm and 370 lb-ft of torque at 5,000 rpm. Built for performance enthusiasts, the Cammer V8 represents Ford’s commitment to delivering cutting-edge technology in crate engine design, providing exceptional power and durability for custom builds.
The engine is mated to a Tremec T5 heavy-duty 5-speed manual transmission. Unlike the standard Focus, which operates with front-wheel drive, the RS8 features a custom rear-wheel-drive system, delivering thrilling handling dynamics and transforming the compact hatchback into a high-performance machine.
Performance That Commands Respect
The numbers speak for themselves: the RS8 rockets from 0 to 60 mph in a blistering 4.4 seconds. This level of performance puts it on par with some of the most celebrated sports cars of its era, making it a true standout among compact vehicles.
A Radical Redesign
Transforming the humble Focus into a rear-wheel-drive monster required substantial engineering modifications. The FRPP team used the European Focus RS as the base platform, stripping it down to the essentials to accommodate the "Cammer" V8.
Key structural changes included:
A custom rear subframe to support the rear-wheel-drive layout.
Reinforcements to the chassis to handle the increased power output and torque.
A revised suspension system for enhanced handling and stability.
Special attention to weight distribution to ensure the RS8 maintained agility despite the larger drivetrain.
Visually, the Focus RS8 retains the compact, aggressive stance of the original Focus RS but is augmented with unique touches that hint at its underlying power. Flared wheel arches house wider tires mounted on lightweight alloy wheels, and functional air intakes provide a focus on performance and cooling.
Interior with a Purpose
The cabin of the RS8 remains functional and driver-centric. Racing-style bucket seats provide support during spirited driving, while subtle branding and performance gauges remind occupants of the car's pedigree. This approach keeps the focus on performance rather than luxury, aligning with the car’s motorsport-inspired ethos.
Showcasing the Cammer V8
The RS8 was not just a concept car but also a rolling showcase for Ford Racing Performance Parts’ capabilities. The project was conceived to highlight the adaptability of the "Cammer" V8, which was available as a crate engine for custom builders. By installing it in a compact Focus, Ford demonstrated the engine’s versatility and its potential for transforming vehicles across various platforms.
Legacy of the RS8
Though the RS8 never saw production, it remains an iconic piece of Ford's history. The car exemplifies the potential of creative engineering and the spirit of customization that continues to resonate with car enthusiasts worldwide. The Focus RS8 also reinforced the Focus brand’s reputation for being much more than an economy car, showcasing its ability to excite and inspire.
In the years since its debut, the RS8 has become a symbol of Ford’s willingness to push boundaries and explore the limits of performance. For fans of the Focus and the broader tuning community, it serves as a reminder of what’s possible when passion and innovation collide.

FORD COSWORTH FOCUS: Refined Racing-Inspired Concept
The mission for Ford Motor Company's performance design team and Cosworth Racing's engine group was simple -- take the new, dynamic Ford Focus and give it racing-inspired hustle. Los Angeles Auto Show onlookers got the first look at the result -- the Ford Cosworth Focus, a well-bred performance concept car based on Ford's all-new small car.
The concept, a clever combination of Cosworth's unmatched Formula One, CART and World Rally heritage and success with Ford Special Vehicle Engineering's penchant for sophisticated driver's cars', blends each group's complementary trademark cues to deliver new standards of refined performance.
Cosworth Focus builds on the impressive production chassis and outstanding driving dynamics of Ford Focus, recently named "European Car of the Year 1999." The production Focus features a multi-link independent rear suspension that gives refined stability while reducing the car's overall weight and noise, vibration and harshness. The North American production version made its debut at the North American International Auto Show in Detroit the first week of January.
"Ford Focus is much more sophisticated than other cars in its class, so it proved to be the perfect vehicle to base a performance concept worthy of the Cosworth name," said O.J. Coletti, chief engineer, Ford Special Vehicle Engineering. "Engineers from Cosworth Racing worked closely with SVE and Ford Advanced Design to build this concept that will appeal to the enthusiastic driver."
Coletti's team turned the already impressive Focus into a thrill ride by lowering the suspension 1.5 inches and adding unique, aerodynamic side rocker panels, front and rear fascias as well as completely original body panels from the glass beltline down.
These unique body parts shape around weight-saving, performance-enhancing 18-inch magnesium wheels shod with Goodyear 235/40ZR18 Eagle GS tires. This combination aggressively takes on the road with adjustable shocks and front and rear variable rate stabilizer bars. The car comes to a quick and steady stop with 14-inch rear, 12-inch front disc brakes with four-piston front and rear calipers.
Perfectly complementing this dynamic chassis package is a Cosworth-developed 2.0L turbocharged DOHC Zetec engine with intercooled induction system that produces an estimated 200 horsepower. The engine is mated to a five-speed MTX- 75 manual transmission with viscous-drive limited slip differential so drivers can push the car with total control.
The powertrain is neatly completed with custom fabricated stainless steel exhaust headers connected to dual 2.S-inch exhaust pipes with low-restriction mufflers. So, while the driver is screaming through the gears, the car dances along to a nice tune.
Inside, drivers are treated to an upgraded interior environment that includes Ford Special Vehicle Team-inspired custom cluster graphics. While driving, each touch will be delightful thanks to upgraded seats, shift knob and steering wheel as well as unique alloy clutch, brake and accelerator pedals.
Much like Ford and Cosworth's Formula One or CART race cars, the Ford Cosworth Focus concept could inspire the best drivers in the world to enjoy Sunday afternoon drives... often.
