When most dedicated car enthusiasts attempt to combine a car and a jet engine, the result is usually dangerous, hideous-looking or a ridiculously expensive combination of the two. When Jay Leno does it, you get the biodiesel-burning Ecojet concept.

Leno and his chief mechanic, Bernard Juchli, came up with the idea and made it happen in about seven months thanks to plenty of help from General Motors. According to Leno, "We wanted to show younger car enthusiasts that environmentally friendly cars don't have to look like a Prius." Ed Welburn, GM design chief, met with Leno to discuss ideas and then turned the project loose within GM's Advanced Projects studio in North Hollywood, California.

According to Juho Suh, whose design was eventually picked by Leno after a highly competitive "sketch off," there were minimal restraints. "We were told it was going to have a jet engine for power and use a Corvete ZO6 chassis; everything else was up to us." Although the turbine power plant recalls some of GM's original Firebird concepts from the '50s, Leno told them to do more than just make a modern-day version of those classic concepts. "I wanted some classic elements, but this wasn't supposed to be Firebird IV; it needed to stand on its own."

Once the design was finalized, Leno's crew of mechanics known as the Bad Dog Garage got to work building the aluminum chassis. Its frame rails, suspension and brakes are all taken straight from the Corvette Z06, but numerous modifications were made to support the new body and the jet turbine engine.

Generating 650 horsepower, the Honeywell LT-101 makes as much horsepower as it does noise. It's hooked to a four-speed Corvette transaxle with special gearing designed to make use of the engine's unique power band. A set of specially designed and built wheels from Alcoa get the power to the ground. Shaped like the fins of a turbine engine, they were used to remind onlookers what they couldn't see buried under the rear hatch.

Saddle Lock Bicycle concept
Designers: Lee Sang Hwa, Kim Jin Ho, Yeo Min Gu

Saddle Lock provides a way to quickly lock the rear wheel without the need for additional locking accessories. The seat post swings down around the main frame when a button is pushed. The saddle features a cut-away shape that allows it to sit over the rear wheel.

A combination lock allows the release of a special alloy rotating lock that extends from one end of the saddle to the other, securing its connection to the wheel.

2007 Chevrolet Trax Concept : Design chief Taewan Kim

Exterior designer of the Trax, Sangyeon Cho, suggests that this little four-door “brings a rational combination of SUV design, function, performance, and value to the consumer.”

Kim Tae-wan, the vice president of GM Korea who heads its design center, recalled the top management’s initial distrust in Korean designers observed during his stint at Daewoo Motors between 1995 and 2000.

NEW YORK – Active buyers who want to get in touch with their sportier side – or who just want to navigate the urban jungle in a sportier ride – will make tracks to the Chevrolet Trax, an urban front-wheel-drive crossover concept with a twist: This micro SUV has an electric limited-slip differential that features an independent battery pack and an electric motor to drive the rear wheels, providing a low-cost all-wheel-drive system.

The four-door Trax is bathed in a Blaze Orange exterior finish, with rugged Burnt Orange accents on the front and rear corners that reinforce the notion this Chevrolet is all business despite its small size. Simple door lines make getting in and out easier; and fold-flat rear seats add functionality.

Other features that suit its dynamic and off-road character include a voluminous, single-unit bumper and fender in front and rear, a pronounced front wheel arch shape, dynamic side character lines, a rear-mounted spare tire and roof rack. Brake calipers in Flame Yellow infuse additional attitude. The package rides on 16-inch wheels and Kumho tires for precise ride and handling.

The Trax is powered by a 1-liter gasoline engine.

"The Trax is a vehicle that you can show off anywhere, be it off-road or on the road," said Sangyeon Cho, manager of the minicar exterior design team at the GM Design Center in Inchon, South Korea. "It brings a rational combination of SUV design, function, performance and value to the consumer."

Mercedes has revealed its entry, the “Ener-G-Force,” which was designed by Hubert Lee in the Mercedes-Benz Advanced Design Studio in Carlsbad, California.

On the eve of the 2012 LA Auto Show, Mercedes-Benz is showing us what it came up with for this year’s Los Angeles Design Challenge. The challenge for this year’s 2012 LA Design Challenge was to create concept for a future police vehicle that is large, efficient and handles all types of terrain.

Of course, for Mercedes-Benz that means the G-Class is the first thing that comes to mind for the designers and engineers at the brand. For years, the G-Class has been regarded as one of the best off-roading SUVs, but this time around we’re getting to see the future of the model has in store in terms of capability, design and efficiency.

“Of course we wanted to take a clear step forward, but we also wanted the G’s characteristic features.”  said Ener-G-Force Designer Hubert Lee.

The Ener-G's tail is its biggest break from tradition. Rounded rear fenders stick out a ways from the body itself, and give the Ener-G haunches the original G never had. Slender tail lamps are still set low in the body, but now wrap around the corner of the car, much like those on the exotic SLS AMG sports car. Despite all this, there's still an abundance of old-school G cues. A duckbill-like kink at the roof's peak echoes the G-Class' drip rail. The tailgate's chamfer recalls a similar recess on the G-Class.

A raised, rectangular portion of the tailgate is offset much like the G-Class's spare tire cover, but holds tools and gear -- not an extra wheel and tire.
The Ener-G-Force's exterior is riddled with clever -- if not quirky -- detail. LED headlamps are cleverly arranged to resemble the letter 'G.' A faux air extractor on each side of the hood echoes those on today's G550 and G63 AMG models. A winch is attractively nestled into the center of the front bumper.

Large, 20-inch wheels use a five-split-spoke pattern, much like today's G. The civilian-grade concept model boasts a four-lamp off-road light pod, while the roof rack boasts integrated accent lighting. Benz suggests a police-spec model would use these spots to install the typical red-and-blue strobe lighting.

“The Ener-G-Force is the vision of an off-roader that, while reflecting tomorrow’s adventures, also invokes the genes of the Mercedes-Benz off-road icon, the G-Class,” said Gorden Wagener, Director of Design at Mercedes-Benz Cars. “Modern and cool, it could also be a clue about a new beginning for the off-road design idiom of Mercedes-Benz.”

The full-scale Ener-G-Force concept was penned—or shall we say, sculpted—by designer Hubert Lee, who was also responsible for the current era CLS. As such, this particular four-wheeled expression offers a fanciful but forceful portrayal of future all-wheel drive law enforcement, less in keeping with the G-Class's traditional ruler-sharp lineography and more along the lines of an über SUV of the future, with the few carryover G-Class style trademarks including cues like fender-mounted turn signal and running lights. From that perspective, Mercedes-Benz’s description of the Ener-G-Force being an expression of "intensity and tension" is spot on—and precisely the reason why we'd love to see one of these bad boys patrolling our streets some day.

Ener-G-Force, which rides on 20-inch wheels and carries recycled water in tanks on the roof, was designed under the leadership of Hubert Lee by the Mercedes-Benz team housed at the company's Advanced Design Studio in Carlsbad, California. The water from the roof-top tanks can be converted to hydrogen that is then fed into fuel cell stacks to generate electricity. Electrical power is then transferred to battery packs in the vehicle's lower side skirts to drive the four wheel-hub motors. Mercedes-Benz estimates the range of the vehicle to be around 800km.

Z-Fixie Concept

Z-FIXIE is a fixed-gear bicycle concept with polished Z-shaped frame.

The top tube, the seat tube, the bottom bracket and the chain stays are connected onto the Z-shaped frame.
The down tube and the seat stays straightly cross through the seat tube.
The frame is designed for a simple and urban look meanwhile keeping high stability from traditional bike structure.


Moving Capsule Concept
Arbo is an extreme transportation concept using electricity and having extra-ordinariliy characteristic appearance. It seems like a captule that is hard to perceive front and rear during driving mode to make its aerodynamic maximized. During 'arbor' mode, the doors are opened in a circle sliding on each doorlines and Arbo is transformed into a perfect space to enjoy the space on the road.

Recharging process
The Primary battery uses the ordinary 110v - 250v electricity. The power is delivered to the ball-wheel drive system. The secondary battery is recharged from the solar energy. It's used for operating Arbo's electric devices. These 2 types of recharging system share the resources together by supplying the power to eachother when one of them is short of power.

Tea - Intimate space concept
Co-work with Myungjin Jung, Jinyoung Jo, Jaesang Lee, Hyun Kim

'Concept Tea' is an interior concept to make passenger's feeling more intimate. The position of seats has been re-organized for changing the layout of what pre-existing cars have, into the new layout that has more connectivity.
The more conversation takes place, the more flowered-mood light appears.

Corvette Stingray Concept Sketch

The Stingray Concept was first unveiled in the 2009 Detroit Motor Show as the 50th Anniversary Corvette Stingray Concept, a homage to the original 1959 Sting Ray Racer Concept which would eventually inspire the second generation C2 Corvette, also known as the Corvette Sting Ray.

Note that many people confuse the name Stingray and Sting Ray. The single word nomenclature actually refers to the third generation C3 Corvette, also known as the Mako Shark, as the design of the C3 Corvette was first previewed in the Mako Shark II concept car. The Stingray name however was dropped by the next model change. Under GM's product placement deal with Michael Bay, the Corvette Stingray Concept earned a starring role for Transformers 2, although screen time was very limited for this character.

Corvette Stingray Concept Sketch

While the coupe Stingray Concept is no stranger to the automotive press and the public, the speedster body type version of the Corvette Stingray Concept however, has never been acknowledged by GM. But pictures taken from film shooting sites of the Transformer 3 confirmed rumours of the existence of a convertible Corvette Stingray Concept. A convertible Corvette is one of the most iconic sports cars in American motoring history, so it won't be surprising to see that a convertible version of the Stingray Concept to appear next. Officially however, GM is mum about plans for a new Corvette or its design direction.

A speedster body is slightly different from a regular convertible - at most, a speedster only has a very rudimentary soft top that needs to be manually installed and can only be driven at low speeds. That is, assuming that the car even has any top at all. While convertibles, even at its most basic (or high performance lightweight package) form will have a foldable fabric top that can be easily pulled up, either manually or electrically and still be able to drive a reasonably fast speed.

A little unknown fact to most petrolheads however, is that the Corvette Stingray Concept, stunning as it seems, was not designed by an American, but a Korean. Sangyup Lee was born and raised in Korea but received his post-grad education in transportation design in Pasadena, California. Thereafter, he have had stints with Porsche AG and Pininfarina and is currently employed by the VW Group as of the Chief Designer of Exterior at the Volkswagen/Audi Advanced studio in California. The current C6 Corvette is also penned by Sangyup Lee.

Sangyup Lee, the General Motors designer credited with the exterior design of the new Chevrolet Camaro, has left the company to join Volkswagen’s Southern California studio.

The joint Audi-VW advanced studio, now in Santa Monica, is famed as the birthplace of the Volkswagen New Beetle and Audi TT concepts. Its longtime head, Derek Jenkins, left to join Mazda earlier this year. Now his successor, the studio’s executive design director Jens Manske, has hired Mr. Lee as chief exterior designer.

Hyundai selected the 2000 Chicago Auto Show to introduce the HCD-V Crosstour concept, a stylish and sporty 5-door alternative vehicle to a traditional SUV. Also billed as the HCD 5, the all-wheel drive Crosstour prototype was powered by a 180 horsepower, 2.7-liter V-6 engine, linked to an automatic tranny. Spacious 5-passenger interior offered SUV-like high seating position, and versatile cargo area.

The HCD-5 was developed by the Hyundai California Design Studio as a 4-seat multi-purpose sedan with an emphasis on station wagon and SUV functions. Powered by a 2.7-liter V6 engine, this crossover car combines the advantages of an SUV and a sedan, and exudes both a retro and sporty feel. There is no B pillar, so the doors open wide to the left and right for easy entry and egress.

The A and C pillars are also made as slender as possible so that the driver's view is left unobstructed. The interior is divided into three spaces. The driver's space features mobile office functions with online access. The back seat is fashioned for ease and comfort, while the roomy rear space is for carrying leisure items.
