Vector Motors:

Vector : Vector Motors Corporation is an American automobile manufacturer originally based in Wilmington, California. Its history can be traced to Vehicle Design Force, which was founded in 1978 by Gerald Wiegert.[1] Vehicle production began in 1989 and ceased in the 1990s. The company was recently revived (as Vector Motors Corporation), and is currently developing a new supercar. Vector is credited by some[citation needed] as America's first attempt to compete with European performance car manufacturers like Ferrari, Lamborghini, and Lotus. Nearly every car produced by the company is designated the letter "W" (for Wiegert) and a number. A letter "X" after the W (e.g. WX-8) signifies a prototype unit. The only exception to this rule is the Megatech-era M12, wherein the "M" stands for Megatech and the 12 signifies its V12 engine.

Rossion Q1:

The Rossion Q1 is a sports car from US car maker 1g Racing/Rossion Automotive. It is based on the Noble M400 and built by Hi-Tech Automotive.[1][2] Founders Ian Grunes and Dean Rosen began development on the Rossion Q1 after acquiring the rights to the Noble M400 in February 2007.[4] Their goal was to design a completely new car fusing the sporty strengths of the M400 with luxurious appointments

Panoz:

Panoz Auto Development is an American manufacturer of high-performance automobiles founded in 1989 by Dan Panoz, son of pharmaceutical and motorsport mogul Don Panoz. The company is located in Braselton, GA. Panoz products have included the Panoz Roadster and AIV Roadster, and the Panoz Esperante. All Panoz road cars are tested exhaustively at Panoz-owned Road Atlanta in Braselton, Georgia and handcrafted at the Braselton works Since 1997, Panoz cars have competed in racing series around the world. Panoz has shifted its American Le Mans and European racing programs toward production-based classes that allow Esperante variants to be raced in modified form. In addition to Le Mans series wins, an Esperante GTLM won the GT2 class at the 2006 24 Hours of Le Mans. For the 2007 American LeMans season, Panoz has contracted longtime BMW Motorsport partner Prototype Technology Group to campaign the GTLM in the ALMS and Le Mans. Panoz has also provided IndyCar with the G-Force IR3 and IR5; and the Champ Car World Series with their race car,

Chaparral:

Chaparral Cars was a United States automobile racing team which built race cars from 1963 through 1970. Chaparral cars was founded in 1962 by Hap Sharp and Jim Hall, a Texas oil magnate with an impressive combination of skills in engineering and race car driving. The combination of the last names of the two founders resembled the Spanish word "Chaparral" (Roadrunner) so it was chosen. Despite winning the Indianapolis 500 in 1980, they left motor racing in 1982. Chaparral cars also featured in the SCCA/CASC Can-Am series and Endurance racing. Chaparral was a leader in effective designing of air dams and spoilers. Their high point being the 1966 2E can-am car. The 2J is the first "ground-effects" car. The unique use of a semi-automatic transmission beginning with the Chaparral 2 is a major reason for their early success. Tires weren't good enough yet to be able to use all the power the 327 Chevy engine could make in 1964, so the torque converter allowed for better traction. The development of the Chaparral chronicles the key changes in race cars in the 1960s and 1970s in both aerodynamics and tires. Jim Hall's training as an engineer taught him to approach problems in a methodical manner and his access to the engineering team at Chevrolet as well as at Firestone changed aerodynamics and race car handling from an art to empirical science. The embryonic data acquisition systems created by the GM research and development group aided these efforts. An interview with Jim Hall by Paul Haney illustrates many of these developments.[1] Canadian Automobile Sport Clubs

BOCAR: The first real production cars, begun in mid-1959 were the XP-5s, on the same wheelbase. The Bocar XP-5 had a glass-reinforced polyester body surrounding a welded moly-tube space frame. Up front was a beefed-up Volkswagen rear suspension. Power customarily came from a 283-cid Corvette V8 engine, producing 290 hp (216 kW) at 6200 rpm.[1] The Bocar was only 34 inches (860 mm) tall, with a four-inch (102 mm) windshield. A variety of options could be ordered: radio, heater, hardtop, seven suspension setups, and choices in wheels and tires. Carburetion or fuel injection could be specified for the Corvette or Pontiac engines. The typical cost was about $8,700.[1] Bodies and frames were also sold separately. The XP-5 was raced by Art Huttinger in the first televised Daytona race in January 1960. It was placed second to the D-Type Jaguar of Ed Rahal.[2] It went on to set a speed record of 175 mph (282 km/h) on the beach of Daytona.[2] After approximately 15 Bocars, Carnes turned to the XP-6, on a longer 104-inch (2,600 mm) wheelbase. This was powered by a supercharged Corvette engine producing close to 400 horsepower. The XP-6 featured a crank-mounted roots-type GMC blower and Corvette fuel injection. Only one was built.[2] The XP-7 was identical to the XP-6, but was naturally aspirated and featured a larger grill opening. The XP-7R was the supercharged version of the XP-7

The Bocar : The Bocar was a series of limited-production two-seaters, developed by Bob Carnes in Lakewood, Colorado. Starting in his own garage, Carnes followed an evolutionary trail from a single, experimental X-1 in 1958. This was followed by X-2 and X-3 examples and about five XP-4s. Early models had a 90-inch (2,300 mm) wheelbase, Jaguar wire wheels, and Girling drum brakes The first real production cars, begun in mid-1959 were the XP-5s, on the same wheelbase. The Bocar XP-5 had a glass-reinforced polyester body surrounding a welded moly-tube space frame. Up front was a beefed-up Volkswagen rear suspension.

Radical:

Radical Sportscars is an auto manufacturer and constructor of racing cars from England. The company was founded in January 1997 by amateur drivers and engineers Mick Hyde and Phil Abbott, who built open-cockpit sportscars which could be registered for road use and run on a track without modification. Although most of Radical's sportscars are road legal, they also build some purpose-built racing cars, such as the SR9 Le Mans prototype The company's first car, the Radical 1100 Clubsport, was based on a Kawasaki motorcycle engine placed inside a small open-cockpit chassis. The cars were intended to run in the 750 Motor Club's races under the Sports 2000 category, with co-founder Hyde driving. In 1999, Radical had built enough 1100 Clubsports that they decided to create a one-make series based around the car. Backed by the British Racing and Sports Car Club, the series featured identical cars that were open to anyone who owned an 1100 Clubsport. The same year, Radical debuted their second model, the Prosport. Available with Kawasaki or Suzuki engine up to 1500 cc in displacement, the Prosports were even more powerful and faster than the Clubsports, and included F3-size slick tyres and an adjustable rear wing. The cars were also brought to the United States for the first time, for use in the SCCA D-Sport class in 2000. Radical's next creation was the two-seater SR3, a car which could compete in international racing, such as the FIA's C3 class. The car uses a Suzuki-based engine tuned by Powertec (now RPE) which offered 1300 cc or 1500 cc versions and a maximum of 252 hp (188 kW) in the latter. A six-speed sequential gearbox was developed specifically for the car to improve performance. The SR3 could also be made road legal in the United Kingdom with the addition of indicators, a hand brake, a catalytic converter, and road legal tyres. In 2006, Radical would make its largest leap into international motorsport with the development of the SR9, a complete Le Mans prototype in the LMP2 class. Official partner Rollcentre Racing would debut the car with success in the Le Mans Series and 24 Hours of Le Mans. Radical was able to move into the CN class of cars, used in VdeV and hillclimbing events throughout Europe, in 2007. The SR5 was based around a Honda VTEC 2.0 L engine which could produce 237 hp (177 kW).
