Iso Rivolta Daytona

The Iso Rivolta Daytona: After Bizzarini left Iso in 1965, Neri and Bonacini were contracted to complete the unfinished design and build prototype bodies. The prototype was displayed to the public at the 1966 Italian Grand Prix at Monza. As many as 5 Iso Daytonas were built and details around their production history and specifications are unclear. One car of this type was showcased in the August 1966 issue of Road and Track, under the name “Nembo II.” The magazine represented this car as derived from Bizzarini’s Iso Grifo and 5300 GT designs but does not mention any official connection with Iso. An Iso Strale Daytona 6000 GT prototype sold at RM Sotheby’s 2010 Monterey auction for $522,500, including buyer’s fee. According to the RM Catalogue, this car was based on a crashed Iso Rivolta and was commissioned by Carlo Bernasconi of Milan, who directed Neri and Bonacini to rebody the car with his own design. The relationship between this car and the Bizzarini/Rivolta Daytona design is unclear. A possible precursor to the Iso Daytona was the 1965 Bizzarini “Nembo,” featured in the May 1966 Road & Track issue. Designed by Bizzarini and finished by Neri and Bonacini, the Iso Rivolta Daytona was nearly identical to an Iso Grifo but used a 7-liter Holman Moody-prepared Ford V8 engine. The subsequent history of this car is unknown.
