Callaway Supercharged Freelander
click here for english
In occasione del SEMA show 2001 che ha luogo a Las Vegas ogni anno in Ottobre, è stata presentata un'edizione speciale del Freelander. Si tratta del Freelander Callaway. Il suo nome deriva da quello del preparatore che si è occupato del make up di questa Land Rover: Reeves Callaway. Callaway è una vera e propria leggenda negli States dove a partire dalla metà degli anni settanta si fece un nome occupandosi di elaborazioni e tuning di vetture sportive. Egli ha continuato la sua carriera fino ai nostri giorni esaltando ogni aspetto dell'ingegneria motoristica e dopo le esperienze nel mondo delle competizioni Reeves si è dedicato alla costruzione e commercializzazione delle proprie dream cars (la C12 e la C12R) oltre a prestare, come in questo caso, la propria opera per altre case costruttrici firmando numerose Limited Editions. Ricordiamo la Callaway Range Rover 4.6 nel 1999 ad oggi la versione dalle più alte performances della Casa di Solihull.
La Callaway presenta una serie di modifiche sia estetiche che funzionali. Fra esse spiccano l'intervento al motore portato a 250 Hp e 36 Kgm a 4000 giri tramite l'adozione di un Supercharger e stimato capace di far accelerare il veicolo da 0-60 mph in 7,7 secondi. L'impianto frenante maggiorato con adozione di dischi autoventilanti e baffati da 332 mm anteriormente e da 304 posteriormente con pinze a 4 pistoni, l'assetto ribassato di 5 centimetri con molle e barre antirollio più rigide e ammortizzatori con una nuova taratura, pneumatici Pirelli P-Zero 255-45-R18Z su cerchi in lega da 18". La vedremo mai in Italia?
Vegas, NV (October 30, 2001)
For the 2001 SEMA show, Callaway and Land Rover have teamed up to debut the “Freelander Supercharged—Performance by Callaway,” an all-new concept that follows closely on the heels of the Freelander’s U.S. introduction. The vibrant Azul Blue concept vehicle elegantly showcases how extraordinary street performance and legendary off-road capability mesh seamlessly in one powerfully engineered package. Sporting a Callaway Freelander badge, the concept defines Callaway’s vehicle development philosophy—as well as the responsiveness, creativity and precision performance engineering capabilities of the Callaway organization.
Developed in just over six weeks, the concept vehicle features a full complement of Callaway enhancements, from extensive engine, chassis and suspension modifications to a beautifully executed exterior design treatment. True to Callaway’s engineering approach, the company’s entire team of seasoned vehicle specialists—spanning two continents, three countries and four separate facilities—contributed to the project. The result is a concept vehicle that delivers the superior performance and distinctive design that today’s driving enthusiast demands, without sacrificing the Freelander’s essential character.
Super Smooth, Super Efficient—This Powerplant Compromises Nothing

“Our engineering objective was to combine superior driveability with the flattest possible torque curve for the broadest range of high performance—all without sacrificing fuel economy,” explained Jim Jones, Callaway’s engine development manager. To achieve this “no compromises” objective, the Callaway Advanced Technology team opted for the supercharged engine application.
Callaway engineers designed and fabricated an exclusive aluminum intake manifold, featuring an optimized intake length that ensures strong, consistent performance from idle through 6200 rpm. In addition, engineers developed an exclusive liquid-cooled intercooler/heat exchanger system. The system features a high-capacity electric pump for rapid water circulation and optimal cooling efficiency. The front-mounted heat exchanger ensures that the Freelander is as cool at idle or low revs as it is powering along the Interstate. The Callaway team also designed an all-new throttle housing, CNC machined from billet aluminum and featuring dual throttle ports and integral idle air control construction. For a flawless finish, a special Callaway carbon fiber engine cover wraps around the Supercharger, hinting at the engine’s remarkable performance.
Callaway also repositioned and modified the entire exhaust system to gain equal power distribution to the twin exhaust pipes. The new performance exhaust includes a stainless steel muffler design, as well as resonated stainless steel exhaust tips. The exhaust outlet area is surrounded by a distinctive dual-purpose billet heat shield. Designed to protect the rear bumper from exhaust heat, the aluminum shield also serves as an aesthetic “finale” by repeating the extruded fastener design elements found in the concept’s wheels.
Performance Includes Custom Chassis and Suspension Refinement.
To channel all that added power in a civilized manner, Callaway applied its engineering expertise to the Freelander’s standard four-wheel independent suspension. Modifications include a full complement of Callaway Sport Tuned increased rate springs and revalved compression rebound dampers, as well as several custom-engineered and machined components, such as a larger-diameter anti-roll bar. The concept sits a full two inches lower than the standard Freelander.
The added performance is matched by equally impressive braking power. Callaway adapted the race car bred Callaway C12’s superb brake system for the Freelander concept The grooved and ventilated front (332 x 32) and rear (304 x 25) rotors are enormous, and well suited to performance driving requirements. A custom aluminum rotor hat, anodized in Callaway blue to match the concept’s brilliant Azul blue body color tops off each rotor. Massive four-piston brake calipers, also adapted from Callaway racing technology, are capable of comfortably managing even the most spirited on- or off-road driving behavior. To direct additional airflow to the concept’s brakes, Callaway also designed and fabricated exclusive carbon fiber brake ducts, integrated in the front bumper.
High- performance 255/45/R18Z Pirelli P-Zero tires are mounted on distinctive 18-inch, two-piece lightweight alloy wheels. The wheels, featuring custom wheel hub pilots, were especially selected for this application by Callaway’s Germany-based competition affiliate, Callaway Competition. The spoke design allows a clear view of the Callaway-branded brake calipers. In addition, each wheel integrates a special Callaway wheel cap.
Exterior Stance Sets Stage for Freelander’s Star Performer Role
Montreal-based designer Paul Deutschman’s artistic sensibilities are fueled by an engineering background, a unique combination of talents that results in vehicle designs that seem to move—even when standing still.
The success of Deutschman’s work is in evidence front to rear. A unique front bumper integrates an aerodynamic splitter, a horizontal extruding lip that provides stabilizing downforce—for when the going gets fast. The splitter is complemented by a metallic silver skid plate—for when the going gets deep and tough. Also designed into the front bumper are Callaway Competition crafted carbon fiber brake duct
Moving toward the rear, the design elements continue to point to the concept’s performance heritage. Rocker panels provide aerodynamic skirting that further enhances vehicle stability at high speeds. Styled to suggest a metallic extruded beam, each rocker sports dual-purpose body colored end caps. True to the vehicle’s dual nature, both on- and off-road enthusiasts needs are met. When wheel flaps are mounted on the rear of the wheel openings, they serve as mud guards. When mounted at the front of the openings, they serve as air deflectors, forcing the air around the tire for less drag at high speeds.
The rear of the Callaway Freelander sports an “air diffuser” lip in the lower bumper area. The final visual focal point is the distinctive aluminum exhaust heat shield that integrates exposed fasteners—a styling element that links directly to the wheel design.
