They’re wild, crazy and oh-so-luxurious. And they represent a vision of the future of luxury motoring.

Now Aston Martin has joined a raft of automakers, including Porsche, Rolls-Royce, BMW and Mercedes-Benz, in releasing new cutting-edge concept cars. The concept models feature sleek designs and the latest technology, which include self-driving systems.

Aston Martin Vanquish Zagato:

Aston Martin showed off its new concept car, the Vanquish Zagato, Monday that was inspired by racing cars. The car features a wing in the back and distinctive round tail lights. Italian design house Zagato included a Z design in the quilted-stitch pattern on the car’s interior and a sleek, curvy exterior to complete the luxury race-car look.

Porsche Mission E: 

Porsche’s new Mission E concept car raises the bar of electric luxury vehicles. With its electric power, it could give California’s Tesla Motors a run for their money if this concept ever gets built, Porsche’s concept model runs on advanced batteries. These batteries allow the car to travel 310 miles on a single charge, and can be recharged up to 80% capacity in 15 minutes. The Mission E has about 600 horsepower and can go from zero-to-62 miles per hour in under 3.5 seconds.

Rolls-Royce Vision Next 100:

The Rolls-Royce Vision Next 100 car boasts the same dimensions as the extended-wheelbase edition of the Phantom, but has been remodeled with a futuristic luxury twist. The interior features a deep-pile ivory wool carpet and a silky wool sofa. Yes, a sofa. The exterior is polished metal with the classic Rolls-Royce “pantheon” grille, the famed Double-R badge and 28-inch wheels. The BMW Group included their vision for a self-driving future in the car’s advanced technological features, which include a virtual assistant that recommends destinations and scheduling, as well as an organic light-emitting diode (OLED) touch screen.

BMW Next 100: 

The BMW Group celebrated its 100th birthday with a glamorous concept car that focuses on connecting as much as possible with the driver. A sedan with “coupe-type sportiness,” the BMW Next 100 concept model virtually suggests ideal paths and speeds to the driver. It includes a self-driving capacity, in which the steering wheel and center console retracts. While the car self-operates, the front passengers are permitted to turn and face those in the rear seat.

Mercedes-Benz Concept IAA:

The Concept IAA is Mercedes-Benz’s answer to uniting luxury-design with maximum-aerodynamic potential. At about 50 miles per hour, the concept car converts to “aerodynamic mode,” in which the rear of the car extends outward and flaps extend around the front bumper to improve air flow around the entire vehicle.
