Gray Design AB has made their name in the European design community with several concepts concerning ultra-luxurious yachts and several more radical automotive examples with Latvian rascals Dartz. The Swedes call themselves the "world leaders in the conceptualization of luxury vehicles for the ultra-wealthy" and the firm has tried to solidify their status with three new built-to-order designs for exclusive automotive collectors.

The new designs, created under the company's Zeus Twelve moniker, are titled the Gold Rush, Magnate and Sigma. Each has its own unique styling and flair while exclusivity remains supreme in its work. Beginning with the Gold Rush model, it runs on a 5.9-liter V12 engine rated at 510 horsepower. Its aerodynamic design features plenty of chrome and gold-painted bits for a very distinct look. Zeus says it can reach a top speed of 188mph. The second model they have released is the track-spec Sigma built entirely from carbon fiber.

With a glass canopy meant for visibility on the track and interior full of luxurious and lightweight materials, the Sigma might be the design firm's pick of the bunch. A dynamic rear wing has been created to optimize downforce while a 355-horsepower 2.0-liter Caterham Duratec straight-four provides plenty of motivation. The Swedes claim it can reach a top speed of 180mph. The third and final design on offer from Zeus Twelve is the Magnate luxury sedan. Complete with rear suicide/falcon doors and a mighty 505-horsepower 6.8-liter V8, the Magnate looks as if a Cadillac front-end and body size grew Aston Martin styling towards the roofline and rear.

Said to reach speeds as high as 184mph, the sedan was "designed for music moguls and celebrities who demand the very best of the best." Bulletproof availability has also been mentioned as well for the quirky car.
