Monterey’s 2026 Car Week is hosting various reveals, including several Porsches that aren’t actually Porsches. The event, which gathers wealthy car collectors in California, has become a platform for showcasing highly limited or one-off new supercars.
Many of these cars come from customisation garages that specialise in restomodding or modernising classics, and modified Porsches are particularly popular. This year’s Car Week features several notable examples, including collaborations between well-known firms and fashion brands.
Singer, a California-based firm, has partnered with Louis Vuitton to create two one-off cars: a Classic coupe and a Turbo convertible. The cars feature unique details, such as a dashboard clock based on Louis Vuitton’s Tambour watch, which can be removed and used as a desk clock.

The Classic model is painted in Louis Vuitton’s signature saffron colour, complemented by blue “demonstration tyres.” The interior has been retrimmed in the fashion firm’s diamond pattern, adding to the car’s exclusive feel.
The Marc Phillip Gembella Marsien GT is another example of a customised Porsche, produced by the son of long-standing Porsche tuner Uwe Gembella. The car is based on a 992 Turbo S and features a RUF-tuned flat-six engine, producing 819bhp and capable of reaching 62mph in 2.4 seconds.
Only 30 Marsien GTs will be produced, making it a highly exclusive offering. The car’s design is inspired by the Porsche 959, and its performance capabilities make it a notable addition to this year’s Car Week.

RUF’s Ehra is another car that isn’t actually a Porsche, featuring an in-house developed carbonfibre monocoque structure chassis and a twin-turbocharged 3.6-litre flat-six engine. The car produces 641bhp, almost twice that of the classic 964 Turbo it’s loosely based on.
Gunther Werks’ GXR-Evo is a 993-based creation designed to go as fast as possible, featuring a 4.0-litre flat-six engine producing 489bhp. The firm has scrutinised every component for weight, bringing the dry figure down, and will only produce 15 versions of the GXR-Evo.
Car Week has become a major platform for car manufacturers and customisation firms to showcase their latest creations, and this year’s event is no exception. They have revealed a range of highly exclusive and high-performance cars, each with its own unique features and design elements.
