Corvette Factory Show Cars 1961 Mako Shark-I, Part 2 – VIDEO

Bill Mitchell’s First Shark Corvette, the 1961 Mako Shark-I

Dateline: 8.7.19 – Photos from GM Archives – Upon Harley Earl’s retirement in 1958, William L. “Bill” Mitchell took over the reins as V.P. of General Motors Design. Earl hired Mitchell in 1935 and Bill essentially learned his trade working under Earl’s guidance. Mitchell was a car guy, an illustrator/designer, and came from the world of advertising. Bill was so good, such a natural, that a year after Earl hired him; he was put in charge of the Cadillac design studio! Mitchell got along famously with Earl, which was not an easy thing to do, as the 6”-4” Harley Earl was known to be a tough and intimidating taskmaster! By 1953, Earl handpicked Mitchell to be his successor, but warned Bill that he’d have to prove himself and make his own mark. Earl’s designs were long, low, and rounded. Mitchell’s philosophy was that a car’s lines should be crisp and sharp, like a freshly pressed business suit.

A year before Mitchell was given the keys to Earl’s Design Kingdom; he was tasked with designing a body for the proposed 1960 Corvette that was to be part of Ed Cole’s line of transaxle-equipped “Q-Chevrolet” cars. One of the members of Mitchell’s advanced design team was Peter Brock, the youngest designer ever hired by GM. One of Brock’s sketches was the closest to what Mitchell had in mind, and became the body for what was later called, the “Q-Corvette”. Unfortunately, the Q-Corvette never made it past a full-size clay mockup, as the entire Q-Chevrolet concept collapsed due to the high cost of tooling for the transaxles. But Mitchell couldn’t let go of Brock’s brilliant design. Shortly after Bill’s big promotion, he indulged himself by deciding to “go racing” with the 1957 Corvette SS mule chassis, draped in a roadster version of the Q-Corvette body design. This became Mitchell’s 1959 Stingray Racer.

Bill’s privateer racing effort wasn’t just “an executive at play”; he was testing the public’s reaction to what he had in mind for the next Corvette – HIS Corvette! Mitchell raced the Stingray Racer for two seasons and it was no secret at the track that the car was his. Even though the body of the car looked nothing like the then current Corvette, and didn’t say “Corvette” anywhere, a Fuel Injected 283 “Corvette” engine powered the car, and it was the VP of GM Styling’s car, so the connection was obvious.

Part of Mitchell’s natural genius was an inner knowing of what the public would like. The public response to the Stingray Racer’s body shape confirmed what Bill knew; the next Corvette would look like his Stingray Racer. Mitchell also understood “show biz” from his time in advertising and through working with Earl on many Motorama events. So, to keep stoking the Corvette and Chevy fans, he created a functional street version of the Stingray Racer. What looked like a prototype Corvette was in actuality another in a long line of teaser show cars. After nine seasons, Corvette lovers were ready for a new machine. The XP-755, aka, the “Mako Shark,” was truly the shape of the future. What Corvette fans didn’t know was that while the Mako Shark was knocking their socks off, Chevrolet was hard at work sorting out the final design of the 1963 Corvette.

This was no small task, as everything except for the engine, transmission, and brakes were completely new. Except for details such as, vent placement, grille, bumper shapes, and the shape of the coupe’s famous, iconic roof section, the second-generation Corvette was nailed down. Bill’s Mako Shark (the XP-755) was an exaggerated version of the work-in-progress 1963 Sting Ray (XP-720). The Mako Shark was a show car to tease the public, as well as Mitchell’s occasional personal daily driver. Think of cars, circa 1961, when looking at the Mako Shark! There were still cars from the late 1920s and 1930s on the road in 1961!

Larry Shinoda was Mitchell’s preferred, go-to stylist guy and seemed to be the best at pulling Bill’s ideas into reality. According to Peter Brock (National Corvette Museum 2017 Hall of Fame inductee), Mitchell was just as tough as Earl, but more jovial and at times profane. Bill just wanted to be “one of the guys”, but he knew what he wanted. (Brock’s book, “Corvette Sting Ray: Genesis of an American Icon” is a MUST READ for all second generation Corvette fans.) Since Larry Shinoda worked out the translation of Brock’s Q-Corvette design into the Stingray Racer, Larry was tasked to do the XP-755, “Mako Shark”. Larry was also working on the XP-720, the 1963 Sting Ray, in its development phase.

Keep in mind that show cars are supposed to be “over the top”. (Remember the 2009 “Transformers” Corvette Concept car?) Since Larry knew every line on the work-in-progress for the 1963 Corvette, he exaggerated and used older elements from the 1958 XP-800. Starting with a stock 1961 Corvette, the Mako Shark-I’s nose and tail had more “point” than the production Sting Ray would have, and was in fact, the nose was 12-inches longer.

Shinoda knew that Mitchell loved “surface details”, so the Mako Shark-I had lots to gawk at, including; gills in front of the front fender opening, recessed areas on the hood, grille details on the hood, tube header side pipes/mufflers, an XP-800-like bubble top with a periscope rear-view mirror system and grille-vents in the back of the bubble, scoops on the rear fender humps, vents behind the rear wheel well openings, and two pairs of triple taillights. The engine was a 327 with a small, Roots-type supercharger and four side-draft carburetors. Outrageous four-pipe side-pipes exited from each front fender. Originally the Mako Shark had a stock 1961 Corvette interior, except for tight bucket seats and a Ferrari steering wheel that was gift from Enzo Ferrari! Chromed Dayton knock-off wire wheels gave the car that “European look”.

Mitchell’s fertile mind was always expanding upon existing show cars and he had no reservation about pulling a show car back into his design studio for a refresh. Years later, the interior was redesigned with flat panels and gauges that looked very Ferrari-like, a 427 engine with an automatic transmission was installed, and Shinoda-designed alloy lace wheels shod with wide tires were used. The bigger wheel/tire combo nicely filled the wheelwell openings.

Unlike many of Harley Earl’s Motorama cars that were basically static, full-size model cars, Mitchell felt that his show cars should be fully functional vehicles, capable of being driven and shown off in public. As much as the completed 1963 Sting Ray is an iconic classic, I believe that if the Mako Shark-I, minus some of the show car pizzazz, had gone into production as the “1963 Corvette Sting Ray” it still would have been a success. Imagine the Mako Shark-I with the Sting Ray roof – that would have been hot! – Scott


 

Corvette’s Founding Fathers, Peter Brock, Pt 6 of 6

Peter Brock: The Man Who Penned the Sting Ray

Dateline: 2-28-19 – Images: GM Archives; Graphics & by K. Scott Teeters

Of the six men in our “Corvette’s Founding Fathers” series, Peter Brock had the shortest career at GM, but his contribution was enormous. Like all of the Founding Fathers, Brock had “gasoline in his veins” and was cut from the same cloth as Larry Shinoda; post-WW-II southern California, the birthplace of modern hot rodding.

Brock got the car bug at the age of 12 when he spotted a 1949 MG TC with a broken engine in back of the garage where he had his first after-school job. Brock studied the lines and mechanicals of the MG TD and at 15 bought the car. With help from his car pals, he got the car running. Brock’s second car was a 1946 Ford that he made into a fast, award-winning hot rod. Whereas Shinoda’s “Chopsticks Special” hot rods were scrappy-looking drag racers, Brock’s Hot Rod Ford was a sleek beauty that was quick at the drags and had class-wins at the Oakland Roadster Show in 1954 and 1956

.While pit crewing for some older car pals that were racing, Brock decided that he wanted to race, but Brock observed that racing was an expensive enterprise. He determined that he’d better first learn a trade. And since automotive design was his second passion, he’d have to go to Art Center College of Design.

Brock’s approach to getting into the school was stunning; he walked in and told the receptionist that he wanted to attend. The lady asked about his portfolio and Brock had to admit he didn’t know what a portfolio was. After she explained, Brock went to his car, created a series of drawings on blue-lined school paper, came back in after a few hours and said, “Here’s my portfolio.” He made his case that after a month, if his work wasn’t approved, he’d leave.

Brock didn’t see much value in life drawing, light and shadow, and graphics classes. But the “Transportation 101” class was exactly what he was looking for. With great teachers, classmates, and his enthusiasm, Brock was ready for his next big break. His only problem was that he ran out of money! GM Designer Chuck Jordan was then working as a headhunter scouting new talent. When Brock explained his situation to Jordan, he received a round-trip ticket to Detroit for an interview with GM, and later a job offer. Brock later said, “GM was like going to the best grad school. The best education a car designer could hope for.” At 19 Brock was the youngest designer ever hired at GM.

Brock couldn’t have been happier and would often work after hours. One evening Design Director Harley Earl entered the design studio and struck up a conversation with Brock. Earl asked Brock what he thought of GM’s design direction. Surprisingly, Brock told Earl that GM needed to look into the small car market because the Europeans was making inroads and GM needed a small “student’s car” for young people that couldn’t afford a new bigger car. Earl was intrigued. After several more evening conversations with Brock, Earl informed Brock that he was starting the XP-79 Cadet project and that Brock was to lead the design effort, under the direction of a studio boss! What an astonishing opportunity!

Brock went through the entire design process, from sketches, and line drawings, to a full-size mockup that looked like a small European GT. Earl loved the concept and expanded it to include a delivery vehicle. But when Earl showed the $1,000 Cadet concept at Styling’s 1958 line review meeting, there was dead silence. GM president Harlow Curtice said, “We don’t build small cars at GM!” The project was dead, but it did plant a seed that soon became the Corvair.

Harley Earl was about to retire, and his Olds Golden Rocket-like C2 Corvette concept was going nowhere. Around the same time the 1957 AMA Racing Ban killed all racing activity. But 46-year-old Bill Mitchell was about to take over as VP of Design upon Earl’s retirement, and had his own ideas of what the next Corvette should look like. The main Chevrolet design studio was where official GM advanced production designs were created, but Mitchell also set up a special Studio X where he could do his own private design work. After returning from the 1957 Turin Auto Show, Mitchell gave his Studio X team photos of cars that most impressed him; the streamliner record cars from Abarth and Stanguellini, and the Alfa Romeo “Disco Volante” coupe. He liked the bulging fenders and sharp horizontal crease line, and instructed his team to sketch some ideas based on the photos.

A few days later, Mitchell came back to review his team’s progress. He carefully looked at all the drawings and stopped at one and said, “Whose work is this?” Brock raised his hand and Mitchell said, “Nice! I’d like everyone to take a closer look here because this approach to the theme has some real possibilities. Your goal is to expand on this. Let’s see how we can approve.” Studio head Bob Veryzer might have been peeved because he put Brock’s drawing away! But during the next review, Mitchell asked, “Where’s that sketch I approved?” Veryzer put the Brock sketch back up and Mitchell said, “Yes, that’s the one! This is what I want!” That’s how Brock got in the lead design team.

Brock refined his design and explored removable roof panels, unique door hinges, and a roll bar built into the B-pillar. Several weeks into the project, Mitchell asked Brock if he knew anything about Earl and Duntov’s 1957 SS Racer. Brock explained that he and several of his designer friends drove around the clock to Sebring to see the car race. Mitchell was impressed and then explained that he had acquired the SS mule chassis and intended to use it as a successor to Earl’s car, and work on it as an “advanced concept”. Thus the XP-87 was born.

Based on Brock’s refined sketches, a work-order was released for a 1/5th scale model to be built. Because of UAW regulations, all of the clay work would have to be done only by the modelers and Brock couldn’t even touch the model. What Brock learned was that the modelers were outstanding, fast professionals, and totally open to his sugestions; they were there to serve the designers. Once again, Brock was learning from the best.

Around the same time, Ed Cole was pushing his Q-Chevrolet line concept that would have all 1960 Chevrolet cars, including the Corvette, use a transaxle for better weight distribution, and to eliminate the interior transmission hump. Duntov’s engineering layout included an all-aluminum fuel injected engine, a four-speed transaxle, four-wheel independent suspension, a platform chassis, and inboard brakes. A full-size space buck was built and Brock and the team translated the 1/5th scale mode into a full-size clay model. Brock commented that with the space buck, everything fell into place. Unfortunately, the entire Q-Chevrolet concept collapsed due to cost and was diluted down to a less expensive car more suitable for production.

Peter Brock explains the Stingray Racer.

But Mitchell still was hooked on Brock’s design. The XP-87 project morphed into Mitchell’s Stingray Racer and then into the 1963 Corvette project, both driven by the capable skills of co-designers Larry Shinoda, Chuck Pohlmann, Tony Lapine, and Gene Garfinkle. Because of the AMA Racing Ban, Brock saw no opportunity to be involved with anything connected to racing, so he left GM on good terms, and went back to California to begin his racing career.

Post GM Brock raced an ex-Le Mans team Cooper and later upgraded to a Lotus II Series 2, coming in runner-up two seasons in a row to veteran racer Frank Monise. Through providence, Brock was Carroll Shelby’s first employee and set up the Carroll Shelby School of High Performance Driving, ran Shelby’s Goodyear Racing Tire operation, helped develop the very first Shelby Cobra. Brock also created the Cobra Daytona Coupe to take on the Ferrari, won an FIA GT World Championship, and World Speed Records at Bonneville.

In 1965 Brock started Brock Racing Enterprises and raced Hinos, Datsuns, and even a NASCAR Mercury until 1972. After Brock decided to end his racing career, he got into hang gliding. In recent years Brock has worked as an automotive photo journalist and authored a book about the Daytona Cobra Coupes, and “Corvette Sting Ray: Genesis of an American Icon. In 2017 Brock was initiated into the National Corvette Museum’s Hall of Fame in 2017. Brock Brock’s single sketch was the beginning of the Sting Ray. Scott

Founding Fathers Pt 3 of 6: Bill Mitchell, Creator of the Corvette Look

When Harley Earl’s XP-122 “Corvette” debuted at the 1953 GM Motorama, the clean design was way ahead of cars of the day. The look reflected Earl’s style; long hood, low, and rounded – a simple yet beautiful design. Earl was five years away from retirement and had already handpicked his replacement, William L. Mitchell. Bill learned the corporate ropes from Earl, and while a faithful lieutenant, had his own unique style that completely changed the look of the Corvette.

This is Mitchell and the 1959 Stingray Racer. Note the red paint and clear hood scoop. This is what the car looked like when it was in the Elvis Presley movie, “Clambake”. See the photos of The King and the 1959 Stingray Racer at the bottom of this post.

One of Mitchell’s famous quotes is, “I got gasoline in my veins!” Mitchell’s father owned a Buick dealership, so Bill grew up surrounded by cars. Born on July 2, 1912 in Greenville, Pennsylvania, as a kid Bill was always drawing cars. His father sent him to Carnegie Tech to learn to draw something besides cars, but it didn’t work. After college Bill got a job at Collier Advertising as an office boy, went to night school for art, and quickly worked his way into the art department. Still “drawing cars”, Bill befriended Sam, Miles, and Barron Jr. Collier with the common interest in, you guessed it, cars.

On the weekends Bill would hang out with the Colliers at their Tarrytown, New York estate, between the Rockefeller and Stillman estates. The guys had a blast roaring around the grounds in MG sports cars. The Collier brothers were so into racing, they started the Sports Car Club of America, and their pal Bill was their official illustrator. Walter Carey, an industrialist and friend of Harley Earl, saw some of Bill’s illustrations and asked him if he ever considered designing cars. Bill answered, “No.” Carey suggests Bill send him some illustrations to forward to Earl. This was the summer of 1935 and by December, Harley Earl hired Bill Mitchell to work as a designer at General Motors. Bill would work for GM until he was 65 years old.

Bill was a natural and a quick learner. A year later, he was in charge of the Cadillac studio! Through the 1930s to the mid-1950s Mitchell created the 1938 Cadillac Sixty Special, the 1949 Cadillac Coupe DeVille, the 1955-1957 Bel Airs, and many other now-classic cars. Mitchell got along very well with Earl and was never on the receiving end of an Earl’s volcanic dress-downs; Bill knew how to “go-along to get-along.” Mitchell liked Earl’s Corvette and since he knew that Earl’s design kingdom would soon be his, had his own vision for a future Corvette.

On May 1, 1954 Mitchell was promoted to GM Director of Design, but still under Harley Earl. To save the struggling Corvette, Earl was directing the next Corvette based on his Olds “Golden Rocket” Motorama show car. The new designs were classic Earl: very rounded, with a bulbous top, a split rear window, and fins. But GM decided to drop Earl’s new concept to reevaluate the Corvette.

Here’s Bill Mitchell with his two favorite fish – the 1959 Stingray Racer and the 1961 Mako Shark-I. Snappy coat, Bill!

Meanwhile, Mitchell’s group was working on what would later be called the “Q-Corvette”. Upon his arrival back from the 1957 Turin Auto Show, Mitchell gave design studio manager, Bob Veryzer’s team photos from the show, with instructions that he liked the bulging fenders and sharp beltline of the Abarth 750 and the Abarth Alfa 1000 streamliner. Mitchell was looking for something new and different. He told the group of designers, “I want this form to be a complete breakaway from what we’ve seen around here in the past.”

Peter Brock was part of the team and was the youngest designer ever hired by GM. Brock described Mitchell as, “… garrulous, rather extroverted and often profane when he wanted to emphasize a point. Mitchell made sure everyone knew he was the boss, but still loved being “one of the guys.” Mitchell closed out his informal meeting saying, “I’ll be back in a few days kids; show me what you’ve got.” The young designers created dozens of sketches with Mitchell keying in on a Peter Brock sketch. The design process went around and around, yet each time Mitchell came back to Brock’s drawing, which eventually became XP-87, the Q-Corvette, which eventually became Mitchell’s 1959 Stingray Racer, but as a roadster.

Mitchell’s Stingray Racer was another chapter in his feisty career. After his promotion to VP of Design and despite GM’s racing ban, he indulged himself by “buying” the mule chassis of the 1957 Corvette SS, and had his guys adapt the Q-Corvette body to the chassis so that he could go racing. In a large meeting, GM president John F. Gordon said, “I thought everyone knew we were out of racing.” Later Mitchell asked Gordon, “Were you talking about me?” Gordon replied, “Damn right I was!” Mitchell asked. “Do I have to quit?” Gordon snorted, “You’ve got to quite right now!” Bill wrote Gordon a letter explaining that he got his job from racing, because that’s what he did – like a doctor going to conventions. Later Mitchell asked Gordon if he’d read the letter and Gordon replied, “I sure as hell did. You’re a good salesman. You can go ahead. Keep it off the property and spend your own money.” Yes, Bill dodged a bullet! Mitchell raced the car for two years and won a championship with no external marking besides, “Stingray”. The fan response was so intense; the next Corvette had be the Stingray.

1963 was a banner year for Bill Mitchell’s cars, as the Sting Ray and his “personal luxury car” the Buick Riviera both arrived. Like the Sting Ray, Mitchell didn’t lay down a single line himself, he knew what he wanted and gave direction until he saw what he was thinking. His instructions for the Riviera were that he wanted to combine a Rolls Royce with a Ferrari. That interesting mix turned into another Mitchell classic.

As soon as the 1963 Sting Ray released, Mitchell got started on the next new Corvette. When he brought in his team of advanced designers, lead by Larry Shinoda, he told them he wanted, “…a “narrow, slim, selfish” center section and coupe body, a prominently tapered tail, an “all of one piece” blending of the upper and lower portions of the body, and prominent wheels with protective fenders that were separate from the main body yet grafted organically to it.” While that sounds obtuse, it does describe the Mako Shark-II. When the Mako Shark-II was shown to management in April 1965, it was unanimous, the next Vette had to be the shark. Outrageously, they wanted it as a 1967 model.

Bill Mitchell’s personality was as intense as his designs. Mitchell didn’t hold division general managers in high esteem, and he hated engineers trying to be designers. He once told a general manager, “I don’t tell you how to make your car or run your plant. Keep your damn nose out of design.” Bill didn’t like smaller cars and once said, “It’s hard to tailor a dwarf.” Mitchell detested focus groups and committees and said, “You can’t design by committee. You have to say, “This is what I want to do.” On the same topic, he said, “Frank Lloyd Wright did not go around ringing doorbells asking people what kind of houses they wanted.”

Many that worked with Mitchell admired him greatly. Designer Roy Lonberger described bill as, “The most authentic man I ever met. His focus never changed, his design vision was laser clear. He changed designs with complete responsibility to design a car. He delegated responsibility, but never abdicated his own. You always knew where you stood with Mitchell because he told you.” Larry Shinoda got along wonderfully with Bill, but Duntov, now so well. They had a famous blowout when Zora came into Bill’s studio complaining about the Sting Ray’s split window. Incensed that a lowly engineer would demand he change his design, a shouting match ensued. Mitchell called Duntov “Zorro” and Duntov called Mitchell a “red-faced baboon”! Duntov was persona-non-grata in Mitchell’s studio for a long time. Designer Robert Cumberford said, “I liked him because he was enthusiastic about things, but he could be crude and vulgar.” Chuck Jordan, eventual VP of Design said, “He certainly loved women. Bill once told me, “If God made anything better than a woman, he kept it for himself.”

When Mitchell retired in December 1977, GM’s upper management decided that never again would they allow a VP of Design with so much power. Mitchell’s successor, Irv Rybicki was totally unlike Bill – some called him a “Yes Man” claiming that’s why 1980s GM’s cars were so boring. A few years before his death in 1988, Mitchell has this to say about the C4 Corvette, “That square box is pretty near plastic… the instrument panel – Dracula’s dressing room… it rides like a truck… it isn’t a style car, it’s an machine car… engineers are running it. Earl would never let that – I would never let that happen, and I condemn the guys for it!” He also said, “My time is over.” Fast forward to the Tom Peters C6 and C6 design era and I believe Bill Mitchell would approve.

Peter Brock was one of the youngest designers ever hired by GM Styling. Ed Cole was the new general manager at Chevrolet and after the success of his small-block Chevy engine design, he wanted to make a follow-up splash by introducing the entire 1960 Chevrolet line of cars equipped with a transaxle, including an all-new Corvette. A transaxle would improve weight distribution and yield more front seat interior space. Continue reading

Yes, the original fan was green.

The entire Q-Chevrolet project quickly fizzled due to cost concerns but several great ideas came out of the project. The unique Peter Brock and Bob Veryzer-designed body eventually was developed into the 1963 Sting Ray. The all-aluminum engine proposal started the ball rolling with aluminum parts gradually seeded into various Corvette engines. While aluminum water pumps, intake manifolds, and bell housings were relatively easy to develop, heads and the block were another story. By the early ‘60s, Duntov began experimenting with aluminum heads, but they proved to be unreliable. The small-block Chevy engine was already a lightweight, but the thought of an even lighter version of the engine was indeed tantalizing.

Corvettes have been powered by all-aluminum engines since the arrival of the LS1 in the all-new C5 1997 Corvette. Of course, today nearly all engines are  made with the lightweight metal. These days, the move is on to integrate even lighter magnesium, carbon fiber, and plastic parts wherever possible. But back in 1957, only the exotic cows of the most expensive European sports cars had all-aluminum engines.So in 1957 when new general manager Ed Cole proposed his Q-Chevrolet line of trans-axle cars, including the Corvette, Zora Arkus-Duntov jumped on the chance. No one inside GM was more tuned into the advantage of an all-aluminum engine than Duntov. The proposal Duntov outlined for his vision of the Q-Corvette included the mandatory trans-axle and an all-aluminum, fuel-injected small-block Chevy engine. The Rochester Fuelie had just arrived and the small-block Chevy engine was only in its third year of production. No one in Detroit was making all-aluminum engines, so this was a very outrageous proposal. Continue reading “Corvettes at Carlisle – First ZL1 Engine Alive and Well!”
