The Maserati Siluro 4CM Carenato was a streamlined land speed record car built in 1937 by Carrozzeria Viotti. Designed by Mario Revelli di Beaumont and Giuseppe Furmanik, it had a radical torpedo-shaped body aimed at reducing aerodynamic drag as much as possible. The car was based on Maserati’s 4CM racing platform and powered by a supercharged 4-cylinder engine that produced 200 horsepower at 7,000 rpm—an impressive output for the era.

On June 2–3, 1937, Furmanik drove the Siluro on the Firenze-Mare motorway in Italy and set a new land speed record in its engine class (1100 to 1500 cc). Using a flying start, he achieved an average speed of 237.568 km/h. The Siluro demonstrated the potential of aerodynamic design and engineering precision in pursuit of high-speed performance during the pre-war era.

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.

While the silhouette still recalls the production New Beetle, nearly every exterior pa

Volkswagen EcoRacer imagines what would happen if a supercar spirit met extreme efficiency. Roughly the size of a compressed Lamborghini Gallardo, the EcoRacer uses a short 97-inch wheelbase and a lightweight carbon-fiber body to deliver performance, economy, and driving fun in one package.

Toyota i-Real Concept was unveiled by Toyota at the Tokyo Motor Show in 2007. It’s a three-wheeled personal mobility vehicle designed to adapt to different speeds, spaces, and user needs through a variable height and wheelbase. At low, walking speeds, the i-Real rides tall and upright on two wheels, using a gyroscope to stay balanced while the third wheel retracts. When traveling faster, the vehicle lowers its stance, extends its body, and deploys all three wheels for better

2005 Toyota FT-SX Concept

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.

2005 Toyota FSC Concept

Toyota FSC is Toyota’s take on a new crossover category that blends a sedan and a minivan. Roughly the size of a Volkswagen Passat Wagon, the FSC is designed as a four-seat vehicle with a spacious, lounge-style cabin, but it can quickly expand to carry up to six passengers thanks to a clever, power-operated, three-stage foldaway third row. The layout sets the FSC apart. Unlike typical crossovers, the rear hatch is split: the upper section opens like a wagon, while the lower s

Toyota Fine-X is a compact four-seat minivan concept and part of Toyota’s “Fine” family of fuel-cell show cars.

The Fine-X uses a compact hydrogen fuel-cell hybrid system mounted under the floor, with four electric motors built directly into the wheel hubs. Each wheel can steer independently—up to 90 degrees—g
