Vector W8
The Vector W8 is a sports car produced by American automobile manufacturer Vector Aeromotive Corporation from 1989 to 1993. It was designed by company founder and chief designer Gerald Wiegert while receiving refinements by Vector's head of engineering David Kostka. The W8 was the production version of the Vector W2 prototype that the company demonstrated throughout the 1980s. History and specifications. The W8 was an improved version of the company's earlier prototype, the W2. Production was delayed after the W2 was presented to the public in 1976 due to a downturn in the world economy and  insufficient financial backing. Wiegert was finally able to secure sufficient financial reserves by the late 1980s, and the company grew from one building and four employees to four buildings and 80 employees, enough to accomplish Wiegert's dream to create his ultimate sports car. The design of the W8 was inspired by the Alfa Romeo Carabo, and continued that car's futuristic, wedge-shaped, aerodynamic design. The W8 combined the design characteristics of the Carabo with references to fighter jets of the era. The company utilized the newest and most advanced aerospace materials in manufacturing the W8, and the term  Aeromotive Engineering was used by the company when referring to the manufacturing process of the W8. Prior to production, the W8 successfully passed DOT crash tests, as well as emissions tests. The semi-aluminum monocoque chassis was epoxy bonded and riveted with an aluminum honeycomb structure floor pan, and 5,000 aircraft specification rivets were used in the car's assembly. The body was made largely of lightweight carbon fiber and Kevlar. The car was based around a Rodeck aluminum resleevable racing engine featuring TRW forged pistons, Carrillo stainless-steel connecting rods, stainless-steel valves, roller rocker arms, a forged crank , a dry-sump oiling system with three separate filters and braided stainless-steel hoses, with anodized red and blue fittings. The transmission was a highly modified Turbo-Hydramatic 425 General Motors three-speed automatic that had been used in front wheel drive Oldsmobile Toronado dating back some two decades earlier. The engine had two intercooled Garrett turbochargers, and had an advertised power output of at 5,700 rpm and of torque at 4,900 rpm on 8 psi of boost pressure. Boost pressure levels were driver adjustable between 8 and 14 psi and during dyno testing at the factory, the engine recorded  a maximum power output of at 14 psi of boost pressure. The W8 utilized special Michelin XGT Plus tires (255/45ZR-16 at the front, 315/40ZR-16 at the rear) bespoke to the car with wide wheels in a design made to the owner's specifications. The W8's suspension utilized double A-arms up front and De Dion tube suspension at the rear, located by four trailing arms that stretched all the way forward to the firewall. Koni adjustable shocks, with concentric springs, were used all around. Brakes were 13-inch vented discs with Alcon aluminum 4-piston calipers at the front  and rear. The interior was upholstered in premium leather and suede, along with wool carpeting and floor mats. Electrically adjustable Recaro leather seats and a premium air-conditioning system completed the luxurious interior. The seating position of the driver was slightly towards the center of the car for better drivability. The dashboard had four display screens with information about the car's status, along with buttons for adjusting the car's various functions. The dashboard displays were similar to fighter jets of the era. Some driving amenities were excluded, such as power-assisted steering and anti-lock brakes, to lower  the curb weight. The W8 generated a skidpad acceleration of 0.97g, the highest in its class. Performance, aerodynamics and production. Vector claimed the W8 could reach a projected top speed of , with acceleration from achievable in a time of 3.9 seconds. During testing at the Bonneville Salt Flats, the W2 prototype attained a maximum speed of with a Donovan aluminum block engine that was less powerful than a production W8's engine, as reported by Top Wheels magazine. This top speed was attained while still using a high downforce rear wing. Later aerodynamic testing further honed efficiency, bringing the  car's drag coefficient (formula_1) down to just 0.32 prior to DOT crash testing in Ann Arbor, Michigan. The W8's design included subtle changes to the body during the production run, so that the initial car off the line looked slightly different from the last. Changes included the elimination of some gills, a lower front fascia and air splitter, and adjustments of the rear wing, mirror intakes, and front grill. After the top speed testing, production Vector W8s were no longer fitted with a removable glass roof due to buffeting that occurred at extreme speeds. Seventeen customer cars and  two pre-production cars were produced before Vector went into receivership in 1993. "Hot Rod Magazine" test results in December 1997: Successor. The AWX-3 and AWX-3R were intended to be the successors of the W8. The model designations stood for Avtech Wiegert Experimental, 3rd generation, with the R suffix meaning the roadster version. Series production of the AWX-3 never began, production of the W8 ended in 1993 after a hostile takeover by the primary shareholder, Megatech. Wiegert sued Megatech and won back the design copyrights, equipment, and remaining unsold cars. In 1995, Megatech began production of the M12 which was  based on the Lamborghini Diablo and was loosely based on the design of the AWX-3. Media and reception. In 1991, the car received negative publicity when tennis star Andre Agassi returned his for a refund after the rear carpeting burned due to an overly hot exhaust system. Agassi had insisted upon delivery before the car was fully prepared, and Vector agreed to deliver it on the condition that the car would be kept in storage and not driven until Vector adjusted the emissions to make it road legal. Also in 1991 "Car and Driver" was unable to complete testing of  the W8 because all three cars provided broke down in different ways. In a 2017 article, the magazine noted that the Vector W8 serves as an example of why they don't believe manufacturer's claims about a vehicle without testing it themselves and described the W8 as "vaporware". In contrast to the negative "Car and Driver" article, "Road & Track" road tested the car without encountering any problems, and published tests of the W8 in its March 1991 and August 1992 issues, praising nearly every aspect of the car's performance. In their tests, the W8 recorded a 0–60 mph  acceleration time of 4.2 seconds. Despite not conducting a top speed test, they provided an estimated top speed based on the redline RPM of the W8's top gear in its 3-speed automatic transmission. The review concluded with: "Hats off to Gerald Wiegert and his team of dedicated engineers, and to all others with the fortitude and determination to have their dreams see the light of day."
