Swedish manufacturer Koenigsegg doesn't build anything but four-wheeled, two-doored supercars. This Koenigsegg Motorcycle Concept shows what a two-wheeled take might look like. Moscow-based designer Maxim Burov imagines the bike as a sleek affair, with wrap-around bodywork that hides the gas tank, engine, and the majority of the rest of the bike's components. The single seat is as short and stout as the bike itself, which lacks a windshield, and, for now, a working prototype.
This isn't the kind of concept car you see at the big auto shows. The Alfa Romeo C18 Concept is purely conceptual, as it doesn't exist at all. Yet. Designed by Antonio Paglia, it's based on the Alfa 8C, and has a swooping body with a "windscreen" that merges with the hood and is covered in a honeycomb pattern. It's unclear whether that would be replaced by traditional glass in a rear-world version, but what is clear is that the car's clean lines, contrasting surfaces, and LED lighting would all look great on the open road.
As rugged as it is handsome, the Kahn Land Rover Defender Double Cab Truck is a useful, luxurious take on the classic SUV. In addition to its wider track, changes include a two inch lift on the suspension, a new paint job in Volcanic Rock Satin with dark red leather and a satin black roof. It rides on new wheels with Renegade tires, and has LED indicator integrated into its new wings and bumpers. Powered by a 2.2 TDCI, 122 hp diesel paired with a manual transmission, it's still not the fastest thing on the road, but it can also go places most vehicles can't.
The sound of a naturally-aspirated V12 is a wonderful thing. The Aston Martin Vanquish S Volante lets you enjoy it without a pesky roof getting in the way. Its aforementioned 5.9L powerplant delivers 594 hp to the rear wheels through an eight-speed transmission, providing plenty of power for open-aired enjoyment. The convertible also receives several other upgrades over the the standard model, including a quad exhaust that's part of the aggressive new rear diffuser.
