Magnetic Selective Ride Control

The Magnetic Selective Ride Control suspension features magneto-rheological dampers able to detect road surfaces, then adjust the shock absorber damping rates to those surfaces almost instantly for optimal ride control. It adjusts damping by means of electromagnetic particles in the shock fluid, with ride control achieved through the precise application of electronic current to manipulate the fluid’s consistency. Two settings are available: “Tour” and “Sport,” which allows you to stiffen suspension capability for better cornering precision during track events. Corvsport Page References:  2005 Corvette.

Mako Shark

The XP-755 Mako Shark concept car was designed by Larry Shinoda under the direction of General Motors Styling and Design head Bill Mitchell in 1961, as a concept for future Chevrolet Corvette production cars. In keeping with the name, the streamlining, pointed snout, and other detailing was partly inspired by the sleek, fast-moving shortfin mako shark. The ’61 Corvette tail was given two additional tail lights (six total) for the concept car. The concept inspired the 1963 Corvette Sting-Ray.  (Information courtesy of Wikipedia.

Mako Shark II

Introduced in 1965, this concept influenced the C3 Corvette design that was introduced in 1968. The Mako Shark II debuted in 1965 as a show car. Chevrolet actually created two of them – only one of which was fully functional. The non-running show car (gallery) sported some interesting, futuristic details, such as square section side pipes and a squared-off steering wheel. While the functioning version didn’t have these features, it did have a retractable rear spoiler, and a square section bumper that could be extended for added protection. The Mako Shark II was powered by a 427 Mark IV engine, which became available on production Corvette models. The paint scheme continued the Shark I tradition, with blue/gray on top and silver/white along the rocker panels. The original Mako Shark was then retroactively called the “Mako Shark I”.

Manifold (Exhaust)

In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe.  Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in US English, as extractors in Australian English, and simply as “tubular manifolds” in UK English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that do not have collectors are called zoomie headers, and are used exclusively on race cars. Information courtesy of Wikipedia.

Manifold (Intake)

In automotive engineering, an inlet manifold or intake manifold is the part of an engine that supplies the fuel/air mixture to the cylinders.  The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is important to optimize the efficiency and performance of the engine. It may also serve as a mount for the carburetor, throttle body, fuel injectors and other components of the engine.  Information courtesy of Wikipedia.

Mark IV Engine

Development of the second generation big-block started with the so-called Mystery Motor (Mark II Z33 427) used in Chevrolet’s 1963 Daytona 500 record-setting stock cars. This “secret” engine was a substantially modified form of the “W” engine, and was subsequently released for production use in mid-1965 as the Mark IV, referred to in sales literature as the “Turbo-Jet V8.” (Content courtesy of Wikipedia.

McLaren, Bruce

August 30, 1937–June 2, 1970. Bruce Leslie McLaren was a New Zealander race-car designer, driver, engineer and inventor. His name lives on in the McLaren team which has been one of the most successful in Formula One Championship history, with McLaren cars and drivers winning a total of 20 world championships. McLaren cars totally dominated CanAm sports car racing with 56 wins (a considerable number of them with him behind the wheel) between 1967 and 1972 (and five constructors’ championships).  They have won three Indianapolis 500 races, as well as the 24 Hours of Le Mans and 12 Hours of Sebring.

McLean, Robert F

A sports car enthusiast and a recent graduate of the California Institute of Technology (Cal Tech), McLean was the engineering designer responsible for the chassis layout of the first Corvette prototypes (Project Opel).  Contrary to common design convention, McLean started his design at the rear axle of the car and worked forward.  His intention was to position the passenger compartment behind the center point of the car, just head of the rear axle.  At the same time, he placed the engine as close as he could to the front bulkhead of the car, allowing Harley Earl’s studio designers to achieve a well-balanced automobile that featured “ground-hugging” bodylines.

Although McLean’s design was developed in the 1950’s, his design concepts are still in use today.  Many attribute his early design as the basis by which classic sports-car proportions are still derived.  As an interesting side note, the original Corvette concept car’s wheelbase was 102 inches, which is precisely the same wheelbase as the Jaguar XK120, of which Earl (and many other designers) drew inspiration for the original Corvette design.

McLellan, David R.:  Born in Munising, Michigan, and a graduate of Wayne State University, he started at GM July 1, 1959.  He was assigned to the Milford Proving Grounds where he began his career as a noise-and-vibration engineer.  In 1968, he transferred to GM’s vehicle dynamic testing program which is where he initially acquired much of his knowledge of automotive handling and suspension technology.  After earning his Masters of Science degree, he began working as a staff engineer under the direction of Zora Arkus-Duntov.

In 1975, he succeeded Duntov as only the second chief engineer in Corvette history.  He inherited a beast of a car — overweight, throttled by emissions hardware — which would get worse before it got better.  David’s low-key, laid-back style hid an intense bull-dog determination to find within the maze of regulation a path to greater glory for the Corvette. He outdid himself. The all-new 1984 car was state-of-the art in aerodynamics, emissions control, weight savings, electronics. Almost a decade after assuming the mantel, Dave had the Corvette headed back to the heights.

Taking a page out of Zora’s book, he began helping Corvette road racers fashion winning programs. To him, the race track was an extension of the proving grounds. With lieutenants like Doug Robinson, John Heinricy, Jim Minneker and Scott Allmon on the front lines, Dave directed a Corvette endurance racing juggernaut so powerful that it was finally dismissed from SCCA competition. In the hands of racing legends like Kim Baker, Tommy Morrison, Dick Guldstrand, Doug Rippie and John Powell, Corvettes won 19 of 19 SCCA endurance races in ’85, ’86 and ’87.

Not to be deterred, Dave and Chevy’s Frank Ellis worked with Powell to launch the million-dollar Corvette Challenge series in ’88. A fabulous showcase for Corvette’s performance, it was also a convenient venue for final development work on McLellan’s most prized baby — the ZR-1.

Featuring Corvette’s first overhead cam engine and bodywork so subtly altered it could easily be confused with the standard Vette, the ZR-1 was introduced to the world automotive press at the 1989 Geneva Auto Show. It was a stunning debut. Almost 15 years after McLellan took over an orphan car line seemingly unsuited for the modern world, the Corvette was universally acknowledged once again as King of the Hill.

On July 2,1992, a smiling McLellan stood by as the one-millionth Corvette was driven off the Bowling Green assembly line. For the quiet kid from Detroit, it was a magnificent moment. Thanks to Dave, the plastic-bodied two-seater born in secret almost 40 years earlier had endured to excite and enthuse still more generations.

Thanks also to Dave, the next generation Corvette (what has become known as the C5) had passed concept initiation before his retirement, on its way to eventual start-up as a 1997 model. In many ways, the C5 was deja vu for McLellan. If external forces almost derailed the Corvette in the ’70s, internal forces made development of the C5 a tumultuous exercise. Awash in red ink, GM second-guessed itself routinely in the late ’80s. As always, the Corvette was a prime cost containment target. The C5 program would emerge as the best Vette yet.

Known as an advocate for pushing the envelope, Dave McLellan wanted to make the Corvette the best possible statement for American technology. Beyond the shadow of doubt, he accomplished such. And one of the major reasons: Dave McLellan. Innovator, educator, Corvette legend, the quiet genius. David R. McLellan biographical content courtesy of The Corvette Museum Website..

William L. “Bill” Mitchell

July 2, 1912 Cleveland, Ohio — September 12, 1988 Royal Oak, Michigan – was an American automobile designer. Mitchell worked briefly as an advertising illustrator and as the official illustrator of the Automobile Racing Club of America before being recruited by Harley Earl to join the Art and Colour division of General Motors in 1935.  Mitchell is responsible for the design of over 72.5 million automobiles produced by GM, including the 1938 Cadillac Sixty Special, the 1963 Buick Riviera, the 1963 Corvette Stingray and the 1970 Chevrolet Camaro.  Mitchell spent the entirety of his 42 year career in automobile design at General Motors, eventually becoming Vice President of Design, a position he held for 19 years until his retirement in 1977.

Mobil 1 Synthetic Oil

The preferred synthetic motor oil used in all GM vehicles – including the Chevy Corvette. Synthetic motor oils – such as Mobil 1 – contain more highly refined base oils than those used in conventional mineral oils, which can offer you better protection and performance. Synthetic oils provide a variety of benefits, such as excellent high- and low-temperature performance, that can provide excellent engine protection.

Both types of engine oil are made from crude oil that comes from the ground. The difference is that synthetic oils undergo numerous additional highly-advanced distilling, refining, and purification processes — and therefore are of a higher purity and quality than conventional mineral oils. This not only removes more impurities from the original crude, it also enables the engineering of the lubricant’s individual molecules to be uniform and consistent, tailored to meet the specific high-performance demands of modern engines. These customized molecules provide higher levels of protection and performance, even in extreme conditions.

The performance of synthetic motor oil is more robust, especially in terms of low-temperature pumpability, high-temperature stability, and protection against deposits. These attributes translate directly into less engine wear and longer engine life.  Infomation courtesy of the Mobil 1 website.

Moss, Stirling: (born 17 September 1929 in London) is a former racing driver from England. His success in a variety of categories placed him among the world’s elite—he is often called “the greatest driver never to win the World Championship”.

Motorama

The General Motors Motorama was an auto show staged by GM from 1949 to 1961. These automobile extravaganzas were designed to whet public appetite and boost automobile sales with displays of fancy prototypes, concept vehicles and other special or halo models. Motorama grew out of Alfred P. Sloan’s yearly industrial luncheons at New York City’s Waldorf Astoria, beginning in 1931. They were almost invariably held in conjunction with the New York Auto Show, that for many years was held traditionally in the first week of January.

The show officially became known as Motorama when it began to travel around the country in 1953. That year more than 1.4 million visitors saw it; Motorama’s opening day in New York drew 45,000 visitors. There was a revue, with orchestra, singers, and dancers. Exhibited at this venue were the Buick Wildcat, Pontiac La Parisienne, Oldsmobile Starfire, Chevrolet Corvette, Cadillac Orleans and Le Mans. More than 1.9 million visitors attended the show in 1954; it started on January 26 in the Waldorf Astoria, New York. On display were the experimental Oldsmobile F88 and Cutlass, Buick Wildcat II, Chevrolet Nomad station wagon, General Motors Firebird XP-21 and Pontiac Bonneville Special, Cadillac El Camino, Cadillac La Espada and Cadillac Park Avenue, all featuring fiberglass bodies. General Motors Motorama content courtesy of Wikipedia.
