Among the many great cars on display at Retromobile last week were two Frua-bodied and V8-engined Maseratis. The rarest and least known of the pair was this 5 Litri Frua Prototipo. Launched at the 1968 Geneva Motor Show, it was the second of three one-offs created by Frua using the Mexico platform. Unlike the name suggests, the unique machine does share the 4.7-litre engine with the production Mexicos. In addition to Retromobile, we also captured the 5 Litri Frua Prototipo at last year's inaugural Chantilly Arts & Elegance concours d'elegance.
One of three built, this 5000 GT Frua Coupe was originally commissioned by the Aga Khan. The Frua-bodied 5000 GTs were easily recognisable by the unique location of the Maserati 'trident' in an additional vent above the grille. Among the subsequent owners of this particular example was actress Rita Hayworth, who previously had been married to the Aga Khan's father.
Over the weekend, BMW released the first images and details of the upcoming M6 GT3. Currently under development, the new GT racer will be powered by a version of the twin-turbo V8 restricted to around to 500 bhp to comply with the regulations.
At the upcoming Geneva Motor Show, Opel and Vauxhall will launch a pair of hot hatches dubbed the Corsa OPC and Corsa VXR respectively. The fastest ever Corsas, they will be powered by a turbocharged, 1.6-litre straight four engine good for just over 200 bhp.
Another car due at Geneva is the McLaren 675LT, which is a reference to the F1 GTR Longtail raced during the 1997 season. The 650S-based machine will be powered by a 666 bhp version of the proprietary twin-turbo V8.
