TheDetroit Autorama, also known asAmerica's Greatest Hot Rod Show, is a showcase ofcustom cars andhot rods held each year atHuntington Place inDetroit, Michigan, in either late February or early March.

It is promoted by Championship Auto Shows Incorporated (CASI) and hosted byMichigan Hot Rod Association (MHRA). It is part of the International Show Car Association (ISCA) schedule for theSummit Racing Equipment Show Car Series, which includes other prestigious show car events such as the Chicago World of Wheels and Houston Autorama.^[1] The show features a selected group of 800 custom and restored vehicles^[2] from across the world^[3] and more than 140,000 spectators annually.^[4]

Detroit's Autorama is best known as home to the Don Ridler Memorial Award,^[5] considered the "Nobel Prize of Hot Rodding". It's presented to the "best in show" at each year's event, and has been won by many well-known car designers and builders, such asChip Foose,Troy Trepanier, Jerry Pennington, and Dave Kindig.

Together, the Detroit Autorama and Ridler Award are considered among the two "Crown Jewel" competitions and awards for professional show car builders in North America, alongside theGrand National Roadster Show and itsAmerica's Most Beautiful Roadster (AMBR) Award.^[6]

The first Detroit Autorama was held at theUniversity of Detroit Memorial Building on January 31 and February 1, 1953.^[7] It featured only 40 cars, and was hosted by members of theMichigan Hot Rod Association (MHRA), which was created only a year before to "organize small local clubs into one unified body that could raise the money needed to pull drag racing off the streets and into a safe environment".^[8] Eventually, the MHRA grew to also include clubs from thecustomizing andhot rodding scene, such as theMotor City Modifieds, Bearing Burners^[9] and Spark Plugs,^[7] who combined efforts to pull-off the first event, along with other Detroit car clubs such as The Road Kings,^[10] Shifters,^[10] and Milwinders.^[10]

For the second show, activities were moved to theMichigan State Fairgrounds Colosseum, where it was held from 1954 to 1960.^[11] For the fourth event in 1956, the MHRA hired a local band and sporting-event promoter Don Ridler to help the show reach a broader audience.^[11] Ridler served as the show's first true promoter until his death in 1963. The following year, the MHRA created a "best in show" award for Autorama, named after the man who made the biggest impact on the show during its infancy.

With increased membership and the success of the first four shows, the MHRA had the necessary capital to build its dragstrip. Motor City Dragway, located inFair Haven, Michigan, opened in 1957 as the first dragstrip in Metro Detroit.^[12] The MHRA would continue to manage both the Detroit Autorama and Motor City Dragway until the track's closure in 1978.^[6]

The 9th Annual Detroit Autorama was the first to be held at the newCobo Hall. That year featured a new-record 230 cars competing, and filled all 10,000 sq ft (930 m²) of Cobo's lower-level basement. The 1961 show's last day also broke the event attendance record by drawing a crowd of approximately 35,000 people.^[13] During these early years at Cobo, the event began to attract industry names from outside the Motor City, including George Barris, Darryl Starbird, Carl Casper, and"Big Daddy" Ed Roth.^[14] And as part ofFord Motor Company's "Ford Custom Car Caravan", the show also generated attention from other big namecustomizers, includingBill Cushenbery, Jack Florence,Dean Jeffries, andGene Winfield.^[15]

In 1964, the MHRA created the Don Ridler Memorial Award to recognize the most "outstanding car shown for the first time ever".^[16] The inaugural Ridler Award went toMacomb's Al Bergler, with an Alcoholslingshotdragster.^[17]

Following Bergler's win in 1964, the next ten years saw growth both in the number of exhibitors,^[6] as well as the number of professional custom car builders competing for the show's new top prize. Early Ridler-winning entries included vehicles built byLarry and Mike Alexander, Jerry Pennington, and George Busti.^[18]

Starting in the early 70s, the MHRA began to incorporate other exhibitions and attractions to Autorama. This includedSoap Box Derbies,^[19] anMPC Model Car Contest,^[20] and theMiss Autorama Contest. The show also began incorporating live acts. Celebrities includingWolf Man Jack,Adam West,Mark Hamill, andLou Ferringo all made autograph appearances at Autorama during the 70's.^[21]Bob Seger performed at three Autoramas in the early 70's.Mitch Ryder,Alice Cooper,Bo Diddley, andChubby Checker also performed during show weekends in the 1970s.^[22]

Builder Jerry Pennington's rear-engine Corvette (Scorpion) and hand-built custom street rod (Devilfish) with their velvet interiors and sharp body lines rank among the most over-the-top and iconic Ridler cars ever built.^[23] 1974's event was a first for Autorama, asWimauma, Florida's Don Campbell and his '27 Ford became the first out-of-state entry to capture the Ridler Award.^[24] The decade was then capped-off with a series of six FordT-bucket Ridler winners.^[24] The roadster trend continued throughout the 1980s, with nine of the next ten Ridler winners being '29 through '34 Fords. The first non-roadster to win the Ridler since 1973 was Dale Hunt's late-modelPro Stock Pontiac Grand Am at the 34th annual Detroit Autorama in 1986. Hunt's Grand Am remains one of only two Pro Stock cars to have won the Ridler (the other being Bob Rizzoli's '92 Mercedes 560 SEC).

Throughout the 1980s and 90s, the Autorama continued to grow into one of the most prestigious car shows in the country.^[6] Fueling growth was a next generation of professional builders and renowned car owners who began to make their way to Cobo every winter in hopes of capturing the Ridler. Among this next generation were California's Bobby Alloway andBoyd Coddington, Memphis'George Poteet, Ohio'sDon Pilkenton, and others. With the influx of new talent in custom car building, the show started to gain national press, with annual coverage inHot Rod and Street Rodder magazines. The only downside to the growing national attention was felt by local Michigan entries. As exhibitors started traveling from across the country, many local Detroit and Michigan customizers became less competitive against those from out-of-state. Though theAlexander Brothers and others continued to build local cars for the show (including a Great-8 competitor in 2012), as of 2023, Dave Emery's 1997-winning Ford Roadster ( Revolver) was the last Michigan-built entry to capture the Ridler.^[25]

The new millennium brought a freshly redesigned Ridler Award trophy, and the creation of the "Great 8" finalist. It also brought a third generation of professional car builders. Wes Rydell's '35 ChevyGrand Master became the first built by designer and TV personalityChip Foose to win the award in 2002. Foose returned again the following year with a '34 Ford,Stallion, for Arizona's Ron Whiteside, which made him only the third builder in the show's history, and the first since Jerry Pennington, to win the award two consecutive years.^[26]

Foose returned again in 2005 with a '36 Ford (Impression), built forLittleton, Colorado's Ken Reister. It was withImpression Foose set a record, joiningDon Pilkenton as only builders to win three Ridler Awards, with Foose being the quickest to accomplish that feat in only a four-year span. Foose would snap his own record yet again ten years later, when his '65 Chevy Impala (Imposter, built for Don and Elma Voth) captured his unprecedented fourth Ridler in 2015.

Following the success of Foose Designs, most Ridler contenders transitioned from individual to professional builds. Ross and Beth Myer's '36 Ford (First Love) was the first Ridler-winner to be built by "Rad Rides By Troy" (Trepanier).^[27] The transition to professional builders continued with T&T Customs (2010), Torq'd Design Lab (2012), Cal Customs (2013), Super Rides By Jordan (2019), and Pro Comp Shop (2022 and '23).^[28]

Since 2008, the roadster trend has begun to fade with only six of the last fifteen Ridler winners being pre-'39 Roadsters.^[29] Most Great 8 Contenders and Ridler winners today are professionally build for clients, with J.F Launier's '64 Buick Riviera as the only owner/builder to capture the award since 1998.

In 2002, the Detroit Autorama celebrated its 50th anniversary with special promotions from Murray's Auto Parts, and inducted an honorary list of "50 People Who Made a Difference". A hall of fame, entitled "The Autorama: Circle of Champions", was also introduced and has inducted at least one member every year since 1997. Inductees includeGeorge Barris (1999),Ed Roth (2000),Crain Communications' Keith Crain (2003),Street Rodder's Brian Brennan (2010),Chip Foose (2013), andHurst Shifter girlLinda Vaughn (2014).^[30] Autorama also introduced for their 50th anniversary a special "Builder of the Year" award to honor past Ridler-winning or major show contributors. Past "Builders of the Year" include theAlexander Brothers (2002),Blackie Gejeian (2004), Ed Roth (2006),So-Cal Speed Shop (2007),Gene Winfield (2008), Darryl Starbird (2009), Bobby Alloway (2011), andTroy Trepanier (2014).^[31]

To celebrate the 50th anniversary of the Ridler Award in 2013, the 61st annual Detroit Autorama "Builder of the Year" exhibit was replaced with the largest gathering of former Ridler-winning cars ever assembled. To cap-off the celebration, the winners of the 50th Ridler Award (Rob & Deb Cizek & their 1940 Ford "Checkered Past") were presented with the first-ever Gold Ridler Award.

During the 2010s and '20's, recognition for the Detroit Autorama among car builders has continued to grow, with contenders traveling as far as Western Australian with hopes of capturing the prestigious Ridler Award.^[32] The growing recognition also led to an expansion ofAutorama EXTREME, a special portion of the show featuring traditionalRat Rods, customs, and other patinaed vehicles.^[33] In 2023, the Detroit Autorama celebrated its 70th anniversary with more than 800 vehicle entries,^[2] over 240 different class awards,^[34] and an estimated 149,000 visitors through the weekend.^[4]

Out of shared competition and history, the Detroit Autorama has become one of the two "Crown Jewels" of professional show car competitions, often sharing cars and builders with the other "Jewel", theGrand National Roadster Show.^[6] Both Autorama's Ridler Award and the GNRS' "America's Most Beautiful Roadster" Award have been awarded annually for over 50 years, both are presented to vehicles being shown for the first time, and both have been won by the likes of Foose, Trepanier, and Alloway.^[35]

The Detroit Autorama has been organized in-collaboration between theMichigan Hot Rod Association (MHRA) and Championship Auto Shows (CASI) since 1961. In 1963, CASI President Bob Larivee Sr. and fellow CASI showrunners formed a new governing body for indoor show car events, titled the International Show Car Association (ISCA). The ISCA has since become the leading governing body of show car events and competitions in North America, with its own rulebook, classification, and points system. Along with CASI (now "North America's largest producer of indoor hot rod shows"^[5]) they co-promote and judge events from coast-to-coast.

The most events ever on an ISCA schedule was 99, set during the 1982–83 season.^[37] The current schedule features 21 long-running indoor events under the "Autorama" and "World of Wheels" banner, including those in Detroit, Chicago, Indianapolis, Pittsburg, Houston, and the ISCA Championship Finals, which are currently held in Cincinnati.^[38] CASI and ISCA combine to promote and judge shows in sixteen states and four provinces, with events running from Thanksgiving weekend through mid-April.^[38]

All ISCA events have a series of "Outstanding Awards" for more than three-dozen classes. Each one counts as a single point in the ISCA standings, which is split into four overall classes: Rod, Custom, Truck, and Bike.^[39][40] If at the end of a season, a single contributor has four Outstanding Awards in a single category, they are locked-into the ISCA Championship Finals.^[41] Many Ridler Winners and Great-8 cars have gone-on to tour the CASI/ISCA event circuit to win an overall Class Championship.^[40]

Autorama's "best in show" award is the Don Ridler Memorial Award, named afterDon Ridler, a formerMichigan State Football Player,Lawrence Tech Basketball and Football Coach and athletic director, and Autorama's first promoter from 1956 to 1963.

It was presented for the first time at the 12th annual Autorama in 1964, and has been awarded annually since.

The Ridler Award winner is selected out of a pre-determined group of eight cars, known as "The Great 8".

On the application for Autorama, a box is to be checked to indicate to the promotional staff if the submitted entry is a Ridler contender. Once entered, each vehicle must meet two specific guidelines in order to qualify for the Great 8, and thus, the Ridler. The entered vehicle must be making its public debut with "limited media exposure", and must be in "minimally operable" condition.^[42]

Once a "Contender" vehicle has met those requirements, it inspected by ISCA judges, who then determine the "Great 8" finalist out of the contender pool.

An entire staff of ISCA Judges are assigned solely to the Great 8 cars, and go through each one before deciding on "the best in show". After a decision is made, the winner is announced alongside more than 240 other vehicle classes^[34] on Sunday Night.

The Ridler Award Trophy, designed by Larry Erickson,^[44] is presented to the vehicle's owner, who is also given an embroidered jacket and a $10,000 check.^[42] Along with receiving a personal Ridler Award, the owner's name is also engraved among the list of past recipients on the full-scale Ridler trophy, which is kept atGM Performance's Headquarters inAuburn Hills, Michigan.^[5]
