Bottom Line Up Front
The Duntov Turbo Corvette is a 1970s‑era C3 that beat the Callaway twin‑turbo to the finish line, offering a turbo‑charged V8, modest fuel mileage, and a price that still feels wild today.

Design & Looks
Zora Arkus‑Duntov took a stock 1971 C3 and added a turbo package without changing the classic fastback silhouette. The car kept the iconic split‑window roof and sharp fender lines, so it still looks like a genuine Corvette at first glance. The only visual clues to its turbo heart are the small air‑intake scoop on the front bumper and a discreet intercooler vent behind the driver’s side wheel.
- Original C3 body, no major body‑kit changes
- Turbo inlet scoop on the front bumper
- Intercooler vent on the rear‑side fender
- Subtle badge reading “Turbo” on the rear deck
Performance & Mileage
Duntov’s team fitted a 5.7‑liter small‑block V8 with a single Garrett turbocharger. The result was roughly 300 hp at 5,800 rpm and a torque peak of 380 lb‑ft. While the power made the C3 feel like a modern supercar, the fuel economy stayed in the 15‑20 mpg range—typical for a muscle car of that era.
| Engine | Mileage | Price | Top Features |
|---|---|---|---|
| 5.7 L V8 + single Garrett turbo | ~15 mpg city / ~20 mpg highway | ≈ $12,500 (1974 market price) |

Price & Rivals
When it rolled out, the Duntov Turbo Corvette cost about $12,500, placing it in the same ballpark as a brand‑new C3 but with a turbo twist that few competitors offered. The closest rival was the 1977 Callaway Turbo‑C3, which debuted a few years later and carried a price tag north of $14,000. Both cars aimed at buyers who wanted more punch without leaving the Chevrolet dealership.
- Original price: ~$12,500 (1974)
- Competed with early Callaway turbo models
- Offered factory‑like reliability thanks to Duntov’s engineering
- Today, a well‑preserved example can fetch six‑figure sums at auction
