Jim Perkins Tribute: R.I.P. Corvette Corporate Angel

Jim Perkins: The Man That Saved the Modern Corvette

(Note: this story was originally published in the March 2019 issue of Vette Vues Magazine) – The Corvette is the most unlikely of all cars for a company such as General Motors to produce. GM is all about producing huge volumes of cars and trucks. When the Corvette came out as a late offering in June 1953, only 300 cars were hand-assembled. Engineers and builders were literally designing as they were building the cars. Sales jumped to 3,640 for 1954 and tanked to just 700 in 1955. Harley Earl restyled the Corvette for 1956 and sales went up to 3,467 units and then 6,339 for 1957. Meanwhile Ford sold 16,155 T-Birds in 1955, 15,631 in 1956, and 21,380 in 1957! They were killing the Corvette then went to a four-seater configuration, leaving Chevrolet the two-seater sports car market all to themselves. Corvette sales didn’t hit 10,000 units until 1960; not much in the big picture of GM!

The long knives were out for the Corvette inside GM. There were many that didn’t understand the Corvette, didn’t like it, and wanted it dead! What saved the Corvette were its corporate angels; Art and Color Section VP, Harley Earl; Chevrolet general manager, Ed Cole; Senior VP of Design, Bill Mitchell; Zora Arkus-Duntov; and Mauri Rose. The common denominator with all of these men is that they are “car guys”. Bill Mitchell was famous for boasting, “I’ve got gasoline in my veins!” Aside from Duntov and Rose, these men had corporate clout; they could lean on and make things happen.

While general manager of Chevrolet, Jim Perkins was famous for handing out pins with the Chevy bow-tie and the work “Pride” beneath it.

In 1960, after some college attendance at Baylor University and three years in the Navy, Jim Perkins took a job at a Chevrolet warehouse, sorting parts while he finished his degree. Little did Perkins know that thirty years later, he too would become a corporate angel for the Corvette.

Perkins was a Depression Era kid from Waco, Texas. When World War II broke out Perkins’ dad tried to enlist in the military but was told he was “too old”. This was a time when men did whatever they had to do to put food on the table. Being mechanically inclined, Perkins’ dad started fixing cars, then buying, and selling cars. Perkins spent a lot of time with his dad and at the age of 14, he got an after school job at a local Texaco service station. Perkins quickly developed a reputation as a very good Chevy mechanic. Perkins fixed and sold a series of cars and finally got a hot ’52 Oldsmobile. But when the ’55 Chevy came out, he sold his Olds and made enough for a new Chevy. From here forward, Perkins was a Chevy car guy!

After graduating from high school, Perkins took courses at Baylor then served three years in the Navy. After his discharge from the Navy, he took a low-level job, sorting parts at a Chevrolet warehouse, while completing his college courses. With his Navy experience and eventual degree, Perkins quickly rose through the ranks at Chevrolet in Sales & Service. In the mid-‘70s, he landed a peach-of-a-job working for then GM president, Pete Estes. That’s where Perkins learned the ropes of GM corporate life.

After a few years working for Estes, Perkins was transferred to Buick. Detroit was struggling to come out of the 1970s recession and how to deal with the success of Japanese cars. Perkins was working under Lloyd Reuss and it was a good relationship. “Just In Time” production was a new concept and Perkins was doing many of the management tasks that Lloyd normally would have done, and he loved it! The first two years they set records; then management changed.

The new top guy at Buick was Don Hackworth and it wasn’t a good mix for Perkins. The two men almost immediately started butting heads. On a plane coming back from a business meeting, Perkins asked Hackworth what they could do to have a better working relationship. Hackworth suggested a “foreign assignment” for Perkins. That was IT for Perkins. What Hackworth didn’t know was that Toyota was wooing Perkins for an executive position. The timing was perfect

When Perkins came into Toyota with his “GM top-down” management style, he was nearly stopped in his tracks. The Japanese car companies were all using the “Consensus Process”; which starts from the bottom (assembly workers) and goes up from there. Perkins quickly learned that while the process takes longer, the execution is like a rocket ship; everyone is onboard and you get better solutions.

A year later, Toyota made Perkins Group V.P. for Sales, Marketing, Distribution, Product Planning, and New Ventures. Around this time Japanese car companies announced that they were taking on the luxury car segment of Mercedes and BMW. Mr. Toyoda wanted to prove to the world that they could build world-class luxury automobiles. Toyota formed Lexus and Perkins was a key player.

Then, an extraordinary thing happened; GM wanted Perkins back! Typically at GM, once you leave, that’s it. Perkins learned from his former boss, Lloyd Reuss, that then-GM president Bob Stemple (another car guy!) wanted to talk to Perkins about coming back. When the two men talked, Perkins told Stemple, “There are two jobs I would come back for; president of GM, or general manager of Chevrolet.” Stemple’s reply was, “Well, that’s a little lofty.” Stemple and Perkins continued their conversation for a time before Stemple called Perkins. “OK, big boy, it’s time to put up of shut up. We’ll make you general manager of Chevrolet.”

It had been twenty-nine years since car guy mechanic Jim Perkins started sorting parts in a Chevrolet warehouse. In May 1989 Perkins was made general manager of Chevrolet. He’s always been a Chevy-guy, and now he was running the division. But when Perkins got back, he was in for a shock. Perkins said in a 2014 interview with Motor Trend, “I didn’t recognize Chevrolet when I got back. It had lost its pride. There was so much infighting among sales, marketing, product planning, distribution, you name it. Everywhere you looked was a silo with its own management, and that’s the kiss of death.”

The CERV IV was really a C5 in drag. Under the stretched body was a full C5 frame and suspension. This is the car that convinced GM management to go ahead with the C5.

TCE” Total Customer Enthusiasm had to start at the top, meaning that managers with bad attitudes had to go. Using Toyota’s “Consensus Process” concept, Perkins invited his people to write to him about the problems they faced and possible solutions. Perkins got 1900 letters, read them all, distilled them into to-do lists, and formed employee councils to come up with working plans. A lot got fixed, workers felt their experience mattered and the organization was much happier. The same concept was also applied to the dealer networks.

By 1990 the nation’s economy was moving into another recession and things were not good inside GM. All car lines were being closely reviewed and Corvette sales were in a downward direction. Once again, the car was on the chopping block. According to Corvette designer, John Cafaro, by 1992 the Corvette almost died. People in the company didn’t understand the car and no one wanted to champion the car. Former GM executive Ralph Kramer said, “Many GM insiders considered the Corvette to be a non-essential product in the GM/Chevrolet stable. The thought that the Corvette would NOT just be in the Chevy stable of cars, but instead the main character; the stud-horse; the Secretariat; was totally remote to the Corvette-haters; but how could it not be otherwise?” (Today, the Corvette is THE flagship of GM)

GM’s Mid-size Car Division managed Joe Spielman (also a car guy and Corvette fan) created a task group called, “The Decision Makers”. The group consisted of himself, Carlisle Davis, John Cafaro, and Dave McLellan. The team’s objective was to create a path for the future of the Corvette. They came up with three directions; First: A production version of the 1990 mid-engine CERV-III; Second: The Momentum Architecture, featuring an evolutionary body style, a stiff backbone-type chassis, and a transaxle; and Third: the “Stiffer and Lighter” design which was a lighter and improved C4. The team chose the “Momentum Architecture”. The problem was funding.

In November 1992 Dave Hill took over as Corvette’s chief engineer and had a big problem on his hands; how to prove the concept of the Momentum Architecture when he had no budget. Corvette manager Russ McLean went the Perkins and explained that the Corvette team needed funding for another CERV Corvette (Corporate Engineering Research Vehicle) to prove the viability of the Momentum Architecture concept. Perkins managed to pull $1.2 Million from another budget to allow Hill’s team to build what is arguably the stealthiest R&D Corvette ever, the CERV IV.

This is the 1995 Indy 500 Corvette Pace Car that Jim Perkins drove to start the 1995 Indy 500.

The CERV IV was essentially a C5 structure wearing a C4 body. A keen eye would have noticed that it looked like a “l-o-n-g” C4 Corvette, but when the car was on public roads, no one noticed. When Hill took executives for a ride, they all said, “This is like no Corvette we ever felt!” Hill proved to GM’s president, Jack Smith, that his team could reinvent the Corvette, as well as the building process. The $1.2 Million that corporate angel Perkins was able to secure for the CERV IV saved the Corvette! It was something that ONLY Jim Perkins could have done.

In 1996, at age 61, Perkins retired from Chevrolet. In his seven years as Chevrolet’s general manager he rekindled Chevy’s 1960’s-style pride; improved Chevy’s truck production; strengthened Chevy’s role in product development and design; helped his people come to grips with downsizing and reorganization, supervised the Chevrolet Racing Team that won five NASCAR Championships and had six Indy Car victories; and got to drive the pace car at the Indy 500 three times in 1990, 1993, and 1995 (in a Corvette).

While it doesn’t look like it, the C5 is the most radical new production Corvette ever offered, thanks to its new hydro-formed perimeter frame, center spine structure, all-aluminum LS1 engine, and transaxle.

In the 2014 Motor Trend interview, Perkins said this about driving the Indy pace car, “You come out of turn four when you’re going to turn them loose, you know you have to make the left turn into the pits, you look down the track, and it looks like everything is closing in on you with all the people and color and movement. You swear you’re going through the eye of a needle. My God, it is such a tremendous, tremendous experience.”

Retirement from Chevrolet only lasted three months when Perkins accepted an offer from Rick Hendricks to take over his company after he came down with leukemia. Perkins stayed on as the CEO and later COO. Perkins said of his time at Hendricks Motorsports, “If ever anything has been rewarding, it has been seeing this company do what it has done. I have no regrets. It’s been a blast, a great, great, great ride.” In 1999 Jim Perkins was inducted into the National Corvette Museum’s Hall of Fame in the GM-Chevrolet Category.

Jim Perkins was a poor kid from depression-era Waco, Texas that liked to work on Chevys. He was described as a “wily, free-speaking, cowboy boot-wearing Texan.” Perkins died on December 28, 2019 in Charlotte, North Carolina. Jim Perkins was 83 years-of-age. Perkins had an exemplary career and most importantly to the Corvette community, saved the Corvette. – Scott


 

Corvette Chassis History, Pt.4: The C5 Chassis That Dave Hill Built

The C5 Corvette’s Momemtim Chassis took the Corvette to a whole new level and paved the way for the C5-R Corvette

Dateline: 1-16-20 – Graphics by K. Scott Teeters, Images from GM archives: Structure is everything. Lessons learned from the C5, C6, and C7 Corvettes is that the stiffer the chassis, the better the suspension can be tuned for improved handling. The C1 to C4 chassis’ were fine for their day, but compared to the modern Corvettes, they leave a lot to be desired, especially if bigger tires and more horsepower is applied. The issue of structure is not new; look at what the Greenwood brothers were doing with the chassis of their widebody IMSA Corvettes in the 1970s. The NASCAR cars of the 1970s had fortress-like cages welded to their frames; but you can’t live with structures like that for streetcars. The arrival of the C5 was a quantum leap in terms of structure.

Joe Spielman ran GM’s Midsize Car Division in 1992 and was responsible for forty-percent of the engineering and manufacturing of GM’s auto production. It was a bad time for GM and despite the Corvette’s iconic status; its future was in jeopardy. Spielman created the “Decision Makers” that included himself, Carlisle Davis, John Cafaro, and Dave McLellan. Three possible formats for the C5 Corvette were created. The first format was the “Momentum Architecture” that featured a stiff backbone, front-engine, rear transmission, and an evolutionary body style. The second format was the “Mid-Engine”, favored by McLellan and GM President Jack Smith. The 1990 CERV III wasn’t just a dream car, it was built with manufacturing in mind, but was going to be complex and expensive. The third format was “Stiffer and Lighter”. This would be the least expensive and was a stiffer, lighter version of the C4. Fortunately, the team went with the “Momentum Architecture”.

The problem was money. When Dave Hill took over, as Corvette chief engineer in November 1992, his 1993 development budget was just $12 million. The estimated total cost to design and develop the C5 was originally $250 million and was cut back to $150 million; GM was in financial trouble and was cutting everything. But Chevrolet general manager Jim Perkins saved the Corvette by juggling an extra $1.2 million so that Hill could build a demonstration car. Another consideration Perkins wanted to see was a “Billy Bob” no-frills concept. Hill’s demonstration Corvette would become the CERV IV, with a manual transmission. Later Hill build an automatic version called the CERV IVb. The “Billy Bob” concept wasn’t developed until 1998 and became the 1999 Hardtop, that later became the now-legendary Z06.

The CERV IV was a true stealth development car. The chassis had the backbone structure of the proposed “Momentum Architecture” plan, but was clothed in a C4 body so that Hill and his team could drive the car on public roads, as well as the Proving Grounds in Michigan and Arizona. To the public it was just another C4 Corvette. Hill’s objectives for the CERV IV were to; prove to GM’s president Jack Smith that his team could reinvent the car, as well as the building process. When Hill took people for test-drives, they said, “This is like no Corvette we ever felt!” Hill’s plan worked, he got his C5 development budget up to $241 million, and set his team to work.

Hill wanted the C5 to be able to do everything as well as, or better than the C4. The C4 had a 350-mile range; Hill wanted 370 for the C5. The solution to the fuel range was a blessing because instead of one tank mounted on top of the rear of the frame, the C5 has two tank placed low on each side of the transaxle. This also helped lower the C5’s center of gravity. Hill wanted a coefficient of drag of .29, the lowest of any production car at that time, so he had to lean on designer John Carfaro.

But the piece de resistance of the C5’s new structure was its hydroformed frame. The first mass-produced automotive application of Hydroforming was for the instrument panel support beam in a 1990 Chrysler mini van. The 1997 C5 Corvette was the first mass-produced automobile to use this manufacturing technique on a major structural component. The frames of all pervious Corvettes were made from sheet steel, bent to form a box section. The box sections were then welded together to form the side rails and cross members. Hydroforming creates complex shapes that are stronger, lighter, and more rigid. After engineers designed the shape of the C5’s frame rails, sheet steel was rolled into a tube, laser-welded, and bent into the basic shape of the frame rail. The shaped tube was then placed inside a form and sealed. Water was then pumped into the tube at 7,000 psi that inflated the steel into the shape. The finished side rail was one, 13-foot long piece, instead of many boxed pieces all welded together. The crossmembers and attachment brackets, (36 pieces in total) were welded by robotic and human welders. Convertibles have 33 parts, one extra for the tonneau cover latch.

The second major structural component on the new C5 was the longitudinal center tunnel backbone. This kind of construction had then only been seen on exotic supercars and racecars. The center backbone creates the driveshaft tunnel and locks the front and rear of the frame together. The C4 designers had a long driveline support torque bar that bolted to the end of the transmission and the rear differential, whereas the designers of the C5 created an enclosed torque tube that bolted to the back of the bellhousing and the front of the transaxle, with a lightweight Metal Matrix Composite (MMC) driveshaft. The torque tube that connects the engine with the transaxle, was then bolted to the frame. Combined with the center backbone, the C5’s chassis structure is four times as stiff as the C4. This was an amazing accomplishment for a mass-produced sportscar.

With the strongest structure ever created for a Corvette, Hill’s suspension engineers were better able to design components to fine tune wheel control. Now the suspension didn’t have to compensate for a flexing structure. The selection of springs, dampers, anti-roll bars and bushings can be more accurate. The C4 suspension was very good and is today used often on street rods. The C5 went to the next level with double A-arms on all four corners of the independent suspension. The new aluminum suspension components are made using the then-new process of casting-and-forging to create lighter, stronger parts.

The C5 came with three levels of suspension. The standard FE1 was for basic driving and used specifically selected fiberglass composite leaf springs, shocks, sway bars, and bushings. The $350 optional Z51 suspension had stiffer springs, shocks, and larger-diameter sway bars. Active suspension options had been around since 1989; the new C5 offered the latest version of the F45 Selective Real Time Damping for $1,695. The C5’s basic dimensions tell us a lot. The C5 is 179.4-inches, 1.1-inches longer than the C4; 73.6-inches wide, 2.9-inches wider than the C4; 47.8-inches in height, 1.5-inches taller than the C4; 104.5-inch wheelbase, 8.3-inches longer than the C4; and 3,221-pounds, 77-pounds lighter than the C4. Wider, lighter, stiffer, with an all-aluminum engine, transaxle, and over 1,200 fewer parts, the C5 was the most revolutionary Corvette to date.Scott

The 2020 Mid-Engine C8 Chevrolet Corvette is HERE!!! – VIDEO

The long and winding road to the mid-engine C8 Corvette

 

 

Dateline 7.18.19 – The waiting is finally over! The “pie-in-the-sky” dream of Zora Arkus-Duntov of a mid-engine high-performance sports car wearing a Corvette badge has arrived. The journey to the mid-engine C8 was long, very long.

The C7 Corvette debuted on January 13, 2013 and by the end of April 2013, Chevrolet announced pricing and hard details. By the third quarter of 2013 C7 deliveries began. Then on August 14, 2014, less than a year after C7 production began, Motor Trend announced online, “SCOOP! Mid-Engine Chevrolet Corvette is a Go”.

I said, “HUH?!?!? The C7 just came out. Come on, quit it with the mid-engine tease!

That was almost five years ago and Corvette fans were tortured mercilessly with rumors, spy images, and 3D renderings. It seemed like “The Never-ending C8 Mid-Engine Corvette Story”. Oh, sure! And now, here we are. The journey to the C8 mid-engine Corvette has become epic.

Duntov passed on in 1996, so we can’t ask him exactly when did he first want a mid-engine Corvette. Duntov knew all about mid-engine sports racing cars dating back to the late 1930s. He built the mid-engine CERV-I in 1959/1960 and the mid-engine, all-wheel-drive CERV-II in 1963/1964.

There were numerous mid-engine cars built at the GM Tech Center in the 1960s that were not specifically Duntov’s cars. The first running, “Duntov” mid-engine vehicle that wore the classic Corvette cross-flags was the 1970 XP-882. This car seriously looked like a Corvette. The 1968 Astro-II looked like a Corvette, but that was R&D chief engineer Frank Winchell’s car. But Duntov got to carry the mid-engine torch.

When Duntov retired and handed over the reins to new chief Corvette engineer Dave McLellan, he told the new chief, “Dave, you must do mid-engine.” Although Duntov was a corporate anomaly during his 21-1/2 years at Chevrolet and many didn’t miss him, he definitely had the hearts of legions of Corvette fans and many GM and Chevrolet insiders.

In 1992 Corvette engineers and managers put three unique proposals on the table for consideration for the C5 Corvette. The three concepts included; the mid-engine CERV-III, a stiffer, lighter, restyled version of the C4, and the “Momentum Architecture”. The CERV-III was too expensive and no one wanted the “stiffer-lighter” concept. The Momentum Architecture design won the contest and became the C5. The C6 and C7 designes are advanced, improved designs of the basic C5 structure.

Jim Perkins was the general manager of Chevrolet in the early ’90s and out of respect for Duntov, he invited the great man to see Dave Hill’s presentation to GM leaders to review past, current, and potential future Corvette designs. Zora didn’t say much.

According to the Motor Trend post on May 4, 2014 titled, “How the C5 Chevrolet Corvette Was Saved”, Perkins had the following exchanges with Duntov a few days later.

Two or three days later, he called and said [imitating Duntov’s Eastern European accent], “Jim, I look at new Corvette architecture, and I am surprised. No mid-engine.” I said, “No, no mid-engine.” He asked, “Why? Why you make decision no mid-engine? You should fight for mid-engine.”

I said, “Zora, I might as well be fighting the wind. I’m not going to win that one. We’ve got the program, we’re going to go forward with it, we have a great architecture that we’re pretty well settled on.” He said, “No, Jim, you must raise issue of mid-engine.” I said, “OK, fine.”

He said, “I would like to come see you.” I said, “Well, I’m pretty busy, but my secretary will try to find a time.” I thought he was going to come in just to talk, but when he walked in that morning, he had a role of stuff under his arm. He said, “I am here to talk about mid-engine car.” I said. “OK, but I don’t know what there is to talk about.”

He rolled out these plans that he had done himself, and started talking about this mid-engine architecture. I said, “Zora, I’d like to sit here and talk with you about this, but I’m very busy, I have other things I need to do. Nothing has changed. We are not going to do a mid-engine.”

He said, “You are not going to fight for mid-engine?” I said, “No, sir. I am not. It’s a waste of time and effort. There is just no point in trying to do it. I know you’re passionate about it, and you’re probably right, but we just cannot do it.” He said, “OK.” And he rolled up his plans, put them under his arm and said, “You are not going to build mid-engine. I will raise the money, and I will build the son-of-a-bitch myself.” And he walked out of the office.”

After decades of jaw, jaw, jaw about a factory production mid-engine Corvette, it is finally here. Some time this summer the last front-engine Corvette will roll off the Bowling Green assembly line, closing the long chapter on front-engine Corvettes. Wherever Duntov’s spirit is in The Multiverse or out there in the Either, we all hope that he is happy that his production mid-engine Corvette is finally a reality. – Scott

1995 Indy 500 Corvette Pace Car – The First “Designer” Indy 500 Corvette

Dateline: 10.22.11

For their third go for the 1995 Indy 500 Corvette, product planners decided to let the designers have at it!

Corvettes have paced the Indy 500 11 times and there have been six Corvette Pace Car replicas offered since 1978. When you look back at the cars in chronological order, there’s an interesting progression. The ‘78 Corvette Pace Car was very stately with its black and silver paint with thin red pin stripping. It was very much of a muscle car-type decoration. The ‘86 Corvette Indy Pace Car couldn’t have been more understated – yellow with lettering on the door. That’s it. Chevrolet hadn’t yet embraced the possibilities of a Corvette Pace Car option and basically wanted to avoid the angst the ‘78 car caused.

But by the time the ‘95 Corvette Indy Pace Car arrived, it was obvious that management let the designers have at it. These cars have to be seen in the daylight to be appreciated. The dark purple metallic paint on the upper portion looks like a lollipop. I don’t know the designer that came up with this design, but BRAVO! Since ‘95 Corvette Indy 500 Pace Cars have been, shall we say, brash, with the exception of the silver & black ‘08 Indy 500 Corvette Pace Car, which was a salute to the first 1978 Indy 500 Corvette Pace Car.
