Ferrari SP38 „Deborah“: a one-off based on the 488 GTB
Ferrari SP38 — a 2018 one-off built on the 488 GTB and named after the client „Deborah“. Here we delve into its origins, inspiration, and technical underpinnings.
SP38 in brief
Ferrari SP38 — a one-off built under the Ferrari „Special Projects“ programme based on the 488 GTB. Often referred to as „Deborah“ after the client Deborah Mayer.
The body has been completely redesigned and inspired by two legendary Ferraris: the F40 and the 308.
History and creation
The „Special Projects“ programme, also known as the „Portfolio Coachbuilding Program“, was launched in 2008 to revive the tradition of creating one-offs and limited-series Ferraris. Engineering and design are handled in-house by Ferrari, sometimes collaborating with external design studios, and the cars receive full homologation for road use.
The SP38 was unveiled in 2018. It is one of the „Special Projects“ cars that combine modern technology with classic Ferrari shapes.
Technology and significance
Based on the 488 GTB with a 3.9-litre twin-turbo V8, which in standard form produces around 670 hp, and a 7-speed dual-clutch gearbox.
This car is significant as one of the most famous examples of Ferrari creating a completely bespoke coupé for a client.
Where to see it and can it be bought
The car was built as a one-off and belongs to the client. It has been displayed at prestigious events, such as the 2018 „Grand Basel“ show.
It's not sold as a single unit, and the price isn't specified.
