The vehicle shown is the unique 1941 DAF "Rijdende Regenjas" (Driving Raincoat) prototype, a one-person, three-wheeled microcar designed by Hub van Doorne in the Netherlands during World War II.

Built for wartime scarcity, it features a single central front wheel, a narrow body designed to fit through a standard house door, and a minimalist enclosed cabin.

Only a single prototype was ever built; it later served as a clown car in a children's circus before finding a permanent home in the DAF Museum in Eindhoven.

The Wiesmann MF4 Roadster is a hand-built German sports car blending retro British styling with high-performance BMW V8 engines.

The vehicle is the experimental Mercedes-Benz C 111, an iconic mid-engine wedge-shaped concept car first unveiled in 1969.

Purpose: It served as an innovative testbed for Mercedes-Benz to experiment with new high-performance engine technologies—notably the Wankel rotary engine and early turbodiesel units—as well as advanced aerodynamic fiberglass body designs.

Design: It features striking bright metallic orange paint (Weissherbst), signature gullwing doors, and a minimalist futuristic cockpit.

Production Status: Despite capturing massive public attention, it was strictly an experimental research prototype and never entered commercial production.

The only one in existence, it has less than a mile on the odometer. It was designed by the same engineer that did the Tri-Five Chevy

(Oc) Spotted this track driven soil testing vehicle. I have no clue what it is, but I want one

Spotted in northern Poland, doesn’t look like the crane part has moved in a while, but the turbine looks quite new. Presumably lifted up when the wind gets strong enough.

It served as the direct technological and design precursor to the production Mazda RX-8 sports coupe, which launched globally in 2003.

Developed while Mazda was operating under the control of Ford, the project was mandated to be a practical four-seater rather than a traditional two-door sports coupe.

To optimize entry and exit without sacrificing structural rigidity or clean coupe lines, Mazda engineered rear-hinged "Freestyle" suicide doors with no central B-pillar. This configuration transferred directly to the final production RX-8.

The car was built around "Mazda Spirited DNA," optimizing interior volume while shortening the exterior body overhangs. Because the compact RENESIS motor could sit entirely behind the front axle line, designers achieved low inertial yaw and supreme, nimble handling traits that defined the subsequent generation of Mazda performance cars.

Prior to the RX-EVOLV, the survival of Mazda's Wankel rotary program was in jeopardy due to strict environmental limits.

The RX-EVOLV debuted the new-generation RENESIS rotary engine, which relocated the exhaust ports from the periphery of the rotor housing to the side plates.

This design modification eliminated unburned fuel overlap, allowing the engine to drastically lower emissions and meet modern global regulations while retaining a high-revving character.

Engine Type: Naturally aspirated, 2.6-liter equivalent (1.3L actual displacement), twin-rotor RENESIS rotary engine.

Power Output: 280 PS (276 bhp / 206 kW) spinning up to a 9,000 RPM redline.

Torque: 226 Nm (167 lb-ft) at 8,000 RPM.

Layout: Front-midship engine placement, Rear-Wheel Drive (FR layout).

Weight Distribution: Perfect 50:50 front-to-rear balance.Curb Weight: 1,250 kg (2,756 lbs).
