The 2006 Ford Reflex Concept was built to prove that a small car did not have to look cheap, soft, or boring. Shown at the 2006 Detroit Auto Show, it was Ford’s answer to the idea that compact cars were becoming more important in America, but still needed attitude, technology, and a clear identity. The Reflex used a diesel-electric hybrid layout aimed at high fuel economy. Ford claimed up to 65 mpg, or roughly 3.6 L/100 km. The system combined a small diesel engine driving th

The 2006 Ford F-250 Super Chief was a heavy-duty pickup concept inspired by America’s old Super Chief passenger trains. It debuted in 2006 as a huge luxury truck with locomotive-style surfacing, a massive grille, rear-hinged rear doors, and a cabin built more like a private railcar than a work truck. The powertrain was the headline. Ford fitted the concept with a supercharged 6.8-liter V10 using a Tri-Flex fuel system, meaning it could run on gasoline, E85 ethanol, or hydroge

The 2006 Dodge Challenger Concept was one of the rare modern concept cars that looked almost production-ready from day one. It debuted at the 2006 North American International Auto Show in Detroit and was designed as a modern interpretation of the 1970 Dodge Challenger, not a loose tribute. The proportions were the point. Dodge kept the long hood, short deck, wide stance, squared-off nose, rear fender kick, and full-width taillight feel that made the original Challenger recog

Unveiled at the North American International Auto Show, the Ford Explorer Sportsman Concept was one of the strangest SUV concepts of the early 2000s. Built around a fly-fishing theme, the concept transformed the familiar Ford Explorer into something far more stylized and experimental. Ford filled the Sportsman with oddly specific outdoors-focused details. The interior used woven leather upholstery alongside custom Bloodwood trim across the dashboard, steering wheel, floor sla

The 2006 Buick Enclave Concept marked a major turning point for Buick, introducing a modern design language and signaling the brand’s shift toward premium crossovers. Unveiled at the North American International Auto Show 2006, the Enclave Concept served as a near-production preview of the model that would launch in 2007.

The 2006 Audi Roadjet Concept introduced a new direction for Audi, blending elements of a hatchback, wagon, and compact MPV into a single premium-focused package. Unveiled at the North American International Auto Show 2006, the Roadjet Concept was designed to explore how Audi could deliver luxury, versatility, and driving dynamics in a smaller footprint, particularly for urban environments.

The Acura RL A-Spec concept, shown in 2005 at the Detroit Auto Show, previewed the A-Spec Performance Package that was later offered on the second-generation Acura RL (KB1). The KB1 RL was the North American version of the fourth-generation Honda Legend. It shared the same all-wheel-drive system, which Acura marketed as Super Handling All-Wheel Drive (SH-AWD).

Volkswagen Ragster (ragtop + speedster) was developed by Volkswagen as a bold reinterpretation of the Volkswagen New Beetle Convertible. The concept kept the Beetle’s recognizable shape but pushed it in a more aggressive, performance-focused direction. The Ragster’s most striking feature is its dramatically lowered roof, achieved by shortening the A-pillars and adding a U-shaped roof frame. While the silhouette still recalls the production New Beetle, nearly every exterior pa

Toyota FT-SX was developed by Calty Design Research in collaboration with Toyota’s Advanced Product Strategy Group and unveiled at the North American International Auto Show.

The FT-SX features a bold, two-volume silhouette with four doors and no B-pillars, making entry and exit easier and opening up the cabin. In
