It’s been a long time coming and well worth the wait.
The ‘20 Corvette Stingray, top, delivers world-class performance and head-turning styling at a fraction of the cost of its imported competition. It represents the culmination of 60 years of mid-engine experimentation. While the eighth generation ’20 VETTE: MID-ENGINED DISRUPTER! Corvette marks a radical leap forward in terms of capability from the seventh generation, it also incorporates lessons learned from past engineering exercises such as the Chevrolet Experimental Research Vehicles, above, (CERVs) I-III, the Aerovette and others.
Zora Arkus-Duntov, considered the father of Corvette, first encountered early mid-engine vehicles in his youth, including the Auto Union Types C and D Grand Prix racecars. Duntov had a wealth of propulsion knowledge and thrived as an auto racer and engineering consultant in automotive and aeronautics. He was attracted to GM by the original Corvette concept, which he saw at the 1953 Motorama in New York City’s Waldorf Astoria.
Duntov started at GM on May 1, 1953, and helped Chevrolet chief engineer Ed Cole turn his proposed Small Block V-8 into a viable technology for Corvette later that decade. Duntov became Corvette’s first true chief engineer and pursued the mid-engine layout through various concepts, including the CERV I, which debuted in 1960. Duntov described it as “a design without limit” and an “admirable tool” to instruct Chevy on “what to put in Corvette.”
CERV I was outfitted with seven different engine combinations in its working lifespan, but its original engine, a Chevrolet Small Block V-8, and its lightweight aluminum core are both modernized on the ‘20 Corvette Stingray.
According to retired GM engineer Ken Kayser’s book, Corvette Legend Or Myth & Zora’s Marque of Excellence, Volume II, Zora’s Fabulous Mid-Ship Corvette History, the very first Corvette with a rear-mounted powertrain actually dates back to 1953-1954! Zora converted his ‘53 Corvette Test Car (EX-54) into the first running Cadet II rear-engine vehicle. It featured an all-aluminum engine coupled to a transaxle and independent rear suspension. That was 65 years ago, in early-1954!
In 1964, Duntov’s team debuted CERV II, which Duntov and Chevrolet General Manager Semon “Bunkie” Knudsen envisioned as a challenger at Sebring, Le Mans and other races. With torque converters in the front and rear, CERV II employed the first-ever mid-engine four-wheel-drive system, for which Duntov held the patent.
The most recent attempt at a mid-engine vehicle was the ‘90 CERV III Concept built in conjunction with Lotus to explore future levels of performance. CERV III, more of a road car than a track performer, was intended as a development vehicle to evaluate mid-engine structures. It was powered by a 5.7L, four-valve DOHC Small Block V-8 with twin turbochargers. It produced 650 horsepower and 655 pound-feet of torque.
Duntov, who retired from GM in 1975, saw the mid-engine layout with the engine located ahead of the rear axle as the optimal configuration for weight distribution, excellent handling and forward visibility. Despite the layout’s innate performance benefits, its implementation in the scheme of mass manufacturing proved problematic. The previous mid-engine Corvettes were relegated to concept status by issues including engine cooling difficulties, limited passenger and luggage space, loudness and the inability to produce a convertible variant.
Advances in development, aided by computer-assisted engineering and virtual reality, helped the current Corvette team carefully plot out the new Corvette Stingray’s architecture. Engineers worked closely with designers to ensure that the vehicle’s form met all of the necessary performance benchmarks, while preserving the Corvette legacy.
Mid-engine was always part of Corvette’s destiny. The ‘20 Corvette Stingray pays off the vision of thousands of people who came before it and lives up to Corvette’s core fundamentals of performance, functionality and attainability.
