Show Rods






Then Cadillac designer Larry Erickson dreamed up the Aluma Coupe hot rod on a flight back to Detroit from Southern California in 1991. Erickson sketched a car conceived as a modern midengine combination of the Pierson Brothers' '34 Ford coupe and Art Chrisman's radically chopped '30 Ford Model A coupe. The car that resulted not only pushed the envelope of hot rod design, but also changed the way the automakers thought about hot rods.

Erickson had worked with Boyd Coddington on CadZZilla™ in the late 1980s, and this car was the duo's next project. It was originally intended to be a roadster with an American V-8, but plans soon changed. Mitsubishi had been thinking of developing a show car based on its 3000 GT sports car, and when Mitsubishi chief product planner Ron Kusumi met Coddington, he found the man who could build a car to showcase his company's parts.

Erickson built a scale model to flesh out and tweak the concept and Coddington's crew set to work. Dave Willey fabricated the tube chassis, which would later be powder coated in gray, as would the suspension parts. The unique front suspension was built as an independent cantilever unit with inboard coil-over shocks, and the rear received an ­independent setup as well.

Marcel DeLay fashioned the body, which changed from a roadster to a coupe along the way due to concerns about structural strength. The car received its name, the Aluma Coupe, in part because the body panels were fabricated entirely from ­aluminum. The frame, made of 1010 steel tubing, includes four wheel independent suspension and hand crafted billet aluminum upper and lower control arms. The control arms alone took over 200 hours to fabricate. The master stroke of course, are Boyd's world famous billet wheels. The body was hand-formed out of over 140 sq. ft. of aluminum sheets cut into individual body panels

Mitsubishi parts shaped much of the rest of the car. Russ Collins of Torrance, California's R.C. Engineering tuned the engine -- a turbocharged 1991 Mitsubishi Eclipse 2.0-liter four-cylinder -- to roughly 320 horsepower. Coddington's crew mounted the engine transversely behind the seats, mating it to a '90 Galant transaxle with billet driveshafts and hub ­carriers.

Erickson also designed the interior, utilizing Mitsubishi Eclipse instruments, custom-made Connolly leather seats, and a Boyd steering wheel. A glass-smooth yellow-pearl paint job and Coddington's Tri-Fan wheels completed the 11-month project.

The Aluma Coupe debuted at the 1992 New York Auto Show to extensive press cover­age. The car further established Coddington as the premier rod builder of his time, and set the stage for further auto company involvement in hot rods.

Ferrari ­collector David Sydorick bought the Aluma Coupe in 1993. He has since displayed the car at the Petersen Auto­motive Museum in L.A., as well as at other venues. Sydorick drives the car on occasion, shows it at South­ern California events, and keeps it at his Beverly Hills home.

The Aluma Coupe's engine is a turbocharged 1991 Mitsubishi Eclipse 2.0-liter four-cylinder.

The Aluma Coupe's interior has custom-made Connolly seats and a Boyd steering wheel.

Boyd Coddington's Aluma Coupe Recently Donated to Petersen Automotive Museum

Iconic Hot Rod Builder's Vision Finds a Permanent Home
From the March, 2010 issue of Street Rodder

The 1925/34 "Round Door" Rolls Royce Phantom I Aerodynamic Coupe. Steve McQueen's 1956 Jaguar XKSS. The Batmobile. Ed Roth's Outlaw. What do these iconic cars have in common? They are all part of the Petersen Automotive Museum Collection. The Petersen Automotive Museum houses a collection of over 300 vehicles that rotate through the many themed galleries to give people a new experience every time they visit. A recent donation has added yet another iconic car, "Aluma Coupe", to the Museum's impressively eclectic collection.

Aluma Coupe was built at Hot Rods by Boyd, founded by the late Boyd Coddington, an icon in the automotive industry, and star of The Learning Channel's American Hot Rod. Long before Hollywood discovered hot rods, Coddington had revolutionized the aftermarket wheel industry along with occasional friend and long time colleague "Lil" John Buttera with what was to be known as the "Billet" wheel. Machining forged billets of aluminum opened up the creative minds of the industry who could now produce limited quantities and one-off set of wheels at a reasonable price. Hot rod and custom car build styles were revolutionized by the high tech look that CNC -machined wheels and accessories created, and the "Boyd Look" was born. (Much like Madonna, Elvis, and Prince, Boyd needs no last name when mentioned to any hot rodder.)

Boyd constantly pushed hot rodding to the next level. When it was time to create a forward-thinking hot rod, he turned to then General Motors Designer Larry Erickson who had designed "CadZZilla", another Boyd-built car for ZZ Top front man Billy F. Gibbons. (Erickson went on to design for Ford Motor Company, and now runs the transportation Design program for the College for Creative Studies.) During the design process, the opportunity to work with Mitsubishi surfaced, and the project soon took off in a unique direction.

Aluma Coupe's one-off, slippery shape and transverse mounted Mitsubishi V-6 mounted in the trunk debuted in Mitsubishi's display at the 1992 New York International Auto Show. In the new car show world, the concept car/hot rod garnered much attention from automotive journalists and show goers for its radical departure from the typical concepts of the day. However, for many traditionalists at hot rod events, the aluminum body's radical shape and the Japanese motor mounted "in the wrong end" of the car was pushing things a bit too far. -But isn't pushing things too far what hot rodding is all about?

"The luxurious, scratch-built Aluma Coupe represented a complete departure from typical design practice by combining traditional styling themes with extremely sophisticated engineering. Like a large number of other vehicles in the Petersen Automotive Museum collection, it demonstrates how the creativity and craftsmanship of local builders can influence the course of an entire movement.", said Petersen Curator Leslie Kendall, of the Museum's latest acquisition. Aluma Coupe is now a permanent part of the Petersen Automotive Museum thanks to the Museum Board Member, David Sydorick, who generously donated the iconic coupe which is now on display and will be shown in future exhibitions whenever possible.
