Yamaha Moto Cage-Six Concept Motorcycle

Serious riders would never mistake Yamaha's XJ6 for a stunt bike — yet that's exactly what was used as the base for the Yamaha Moto Cage-Six Concept Motorcycle ($TBA). Being a concept, it will likely never become available, but that doesn't mean we can't enjoy the garish paint scheme, exposed framework, and car tire-carrying rear wheel. [via]

Audi Crosslane Coupe Concept

It might look like a cross between an SUV and an A1, but according to the company, the Audi Crosslane Coupe Concept ($TBA) puts an extreme stress on the "Coupe". Built atop a Multimaterial Space Frame, it's powered by a plug-in hybrid drive that pairs a 1.5L three-cylinder TFSI engine and two electric motors, giving it 177 hp, a 0-62 mph time of 8.6 seconds, and astonishing 213 mpg fuel economy. Other features include a 2+2 seat layout, a unique electrically-powered trunk, trapezoidal LED headlights, and a stylish interior.

Porsche Panamera Sport Turismo Concept

We've seen a Porsche SUV, a Porsche Sedan, but a Porsche wagon? Yup, that's exactly what the Porsche Panamera Sport Turismo Concept ($TBA) brings to the table. The surprisingly sleek Sport Turismo seems to borrow inspiration from the Cayenne, 911, and Boxster, with an agressive front end with LED headlights, a more distinctly sloped rear with LED tail lights, and an adaptive carbon rear spoiler. Power is supplied by a new plug-in e-hybrid system that combines a 95hp electric motor with a 333hp supercharged V6, all of which means a 0-62 mph time of under six seconds. Of course, this is a concept, so it also features a new crazy blue paint job, an unrealistically futuristic interior, and no guarantee that it will ever come to market.

McLaren P1

When is a car even more nebulous than a concept? When it's a "design study". The McLaren P1 ($TBA) is a perfect example. While the design of the final product is sure to be close to what we're viewing here — and that's certainly a good thing — the specs are shrouded in mystery. All we're promised is "the best driver's car in the world on the road and track", which we hope is good enough for anyone ponying up the cash for this beast when it goes on sale in the next year.

Peugeot RCZ R Concept

Most concepts arrive with no clue as to whether they'll ever become reality, but luckily for our European friends it appears the Peugeot RCZ R Concept ($TBA) — or something very similar — will be rolling out to dealerships at the end of 2013. Details remain scant, but we do know that the 1.6L THP engine will give it 260 hp, making it the most powerful production model in Peugeot history, and that it sports a racy body and a Torsen limited slip differential. No word on whether the concept's surprisingly catchy black and copper paint scheme will make the cut.

BMW Zagato Roadster

How do you make a car as stylish as the BMW Zagato Coupe even better? Chop off the roof, of course. The new BMW Zagato Roadster ($TBA), is, like its predecessor, based on the Z4, and features a similarly upgraded body and interior, including 19-inch light-alloy wheels, an exclusive gray exterior paint finish, brown, leather-wrapped roll bars inspired by airplane design, and a more elegant tail end. Unfortunately, it shares something else with its stablemate — it's not for sale.

McLaren X-1 Concept

Enjoy these photos of the McLaren X-1 Concept ($TBA), because it's probably as close as you'll ever get to one. Created by McLaren Special Operations for an anonymous client — one who already owned a a McLaren F1, a Mercedes-Benz SLR McLaren and a 12C, in case you needed more reason to be jealous — the X-1 is structurally based on a carbon MonoCell but features a totally unique body that recalls the classic, swooping lines of cars gone by. Otherwise, it's much like the 12C, right down to the twin-turbo 625PS engine which gives it "astonishing" acceleration and top speed. Guess we'll have to take their word for it.

Hyundai Zombie Survival Machine

Why buy a beat up van to ruggedize for the apocalypse when you pick up a new ride right off the showroom floor? While it's unlikely to appear at dealerships anytime soon, the Hyundai Zombie Survival Machine ($TBA) is certainly ready for any undead action that comes its way. Based on the Elantra Coupe, it features a custom zombie plow — complete with spikes — out in front, armored window coverings, a roof hatch, a trunkfull of weaponry, floodlights in the front and back, spiked all-terrain tires, wheels with spikes for clipping nearby walkers, and an all-important CB radio system. After all, you don't really expect your cell phone to work during the end times, do you?

Volvo S60 Polestar Concept

Volvo fans looking for the ultimate in Scandinavian performance, take notice. The Volvo S60 Polestar Concept ($TBA) might still be a concept, but what a concept it is. Powered by a specially tuned Volvo T6 engine pumping out 508 hp, it dashes from 0-62 mph in just 3.9 seconds, on its way to a top speed of over 185 mph. Other features include a reinforced manual six-speed gearbox, all-wheel-drive, 19-inch wheels, a lowered chassis, front Brembo brakes, a carbon fiber diffuser, more supportive, Polestar seats, and an Alcantara-covered interior. Will it ever actually be made available? Depends on the always fickle "market response."

BMW Zagato Coupe

Rekindling a partnership that dates back over 50 years, the BMW Zagato Coupe ($TBA) wears its Italian design heritage proudly. Details are scant on this shapely coupe, which features Zagato "z" letters in the signature kidney grille, 19-inch alloy wheels that recall propellers, and a double-bubble roof. We can only guess that it's based on the Z4 roadster, but it doesn't really matter, as this is the only one that exists.

Mercedes-Benz Style Coupe Concept

You would expect a car with "style" in its name to focus on aesthetics, and the Mercedes-Benz Style Coupe Concept ($TBA) doesn't disappoint. Defined by a striking exterior, it features innovative, aggressive new headlamps and taillights, a diamond-look grille, muscular lines, 20-inch wheels, and a special Alubeam paint finish, a tested, road-ready turbocharged 2.0L four-cylinder engine, and a funky interior that's highlighted by a panoramic glass roof, the lack of B-pillars, a carbon fiber dash, white nubuck leather on the instrument panel, air vents that change color based on the selected temperature, neon green accents, and a new version of MB's COMAND system that uses your smartphone's data connection to stay up-to-date. While we doubt all of this will make it in to an actual car you can buy, you can bank on seeing some of these features make their way into the next CLS.

Peugeot Urban Crossover Concept

While it's highly unlikely to ever appear stateside, we're intrigued by the Peugeot Urban Crossover Concept ($TBA) nonetheless. Designed to blend the utility of an SUV with the city-friendliness of a compact, the Concept measures just 13.5 feet long and 5.7 feet wide. As with most concepts, further details are scant, but we'd expect to see the aluminum spoiler, double-bubble roof, and floating, "smiling" grille make it to the production model should it ever emerge.
