Automotive design is an odd beast that usually ends up being a product of compromise and costs concerns after long hours in board meetings and design studios filled with creative minds that don’t always agree. One man, however, has broken that tradition and designed a car from the ground up to be a single entity, appealing to both the male and female buyer through specific design elements and featured content.

Timur Bozca is that man and his Bozca Zest concept is a truly unique piece of automotive design. The philosophy behind the Zest is, according to Bozca, one of equality between the sexes and what each desires in a vehicle. Men look for performance and stunning designs, while women desire creature comforts, useful interiors, and storage space.

Not only is the Zest an exercise in clever design, but its powertrain is something to be admired. An Audi-sourced, 2.5-liter, turbocharged five-cylinder with direct injection makes its home under the hood and produces 335 horsepower and 331 pound-feet of torque. The gasoline engine does not power the car, however. Rather, four synchronized electric motors at each wheel receive power from the gas engine and 84 kg (185-pound) on-board batteries to propel the Zest forward – with the ability to hit 62 mph from in just 5.5 seconds. Regenerative braking, photovoltaic panels on the transparent roof, and full-on, plug-in-hybrid capabilities (PHEV) mean the Zest is highly efficient while being performance oriented.

The Zest also boasts a composite chassis that aids in reducing the car’s overall weight to just 1,200 kg (2645 pounds). Carbon fiber is used extensively and is even employed in crash zones to help absorb impacts. The body panels are comprised of a sandwiched material of linen and cork bonded together with epoxy resin. The result is a lightweight, yet strong exterior that also boasts a drag coefficient of only 0.35 Cd.

The forward-thinking, futuristic design features a full-glass roof that flows from the A-pillars down to the rear bumper and lends itself to an airy, open feeling in the cabin. Sculpted sides accentuate the butterfly doors, which open like those found on Lamborghinis. The blacked-out wheels were inspired by water lilies and are constructed from recycled aluminum.

Currently, the automotive industry is still accused of not appreciating women as being car owners and car purchasers in their own right and that instead of focusing on the needs of women themselves, the industry still assumes that car purchasing decisions are still largely made by men rather than by women. Accordingly, the Bozca Zest will focus on establishing the need for a new type of vehicle, which offers the advantages of a car in a package more suited to the female equally male drivers and establishing what are the requirements of they are in such a vehicle in city life.

The concept sets out to establish what makes a vehicle physiologically and psychologically practical and appealing to women & men drivers. As the vehicle is designed for both genders, female’s characteristics differ from a male’s expectation of a vehicle. Men want the vehicle to look sporty and to get to their destination fast, where as female wants their creature comforts, useful interior like lots of storage area for carrying things such as accessories. Additionally, females want to the vehicle to be accessible where they can drive with heels, adjust dials with long nails and access the vehicle with short skirt without exposing anything.


The point of which was to discover the aesthetic preferences of the target users, aims high quality luxury market. Women prefer soft, organic, marginal and luxury structures and also technological and functional features. On the other hand, men prefer sharp, hard, sporty, fast looks.

The Bozca Zest’s design is aiming both genders’ aesthetic preferences. Main inspiration of the car is a Falcon; headlights–eye, front part–beak, doors-wings and back part is like its tail. As a designer, in my opinion falcon is an animal, which is fragile, sharp, beautiful, feminine…etc. Females are more selective than males; this is why its design has more feminine features. About male side, the strategy is approaching them with dynamic sporty-aggressive look and high technology on the board.

The concept has two big doors in wing shape which is opening like butterfly doors. It is making the car similar with real falcon’s wing moves.
There is no rear mirror in the Bozca Zest. Instead of it, there are cameras to show rear part in the large screen.

Rims are one of the most important parts of the car for appearance. Therefore, I work on the rims design separately to give it some emotion. When I was designing them, I was inspired by water lily, which is rare and elegant flower. The Bozca Zest design inspirations are from nature for make it fit to the environment.

Both genders don’t like to spend their moments in narrow place while they are driving. The roof of the Bozca Zest is formed by glass so interior will have big amount of skylight. This is providing fresh feeling in narrow areas for drivers.

About interior, there have some woman-friendly features such as; touch screens for easier click with long nails, center console spacious enough to stow a handbag, carved-out door panels to help keep rings from getting whacked when window switches are used, more compartments… Additionally, the accelerator is equipped with an adjustable heel support and pedal so these different tilts to the accelerator pedal that makes driving in high heels safer and more comfortable.

Blue light is used more for interior lighting as an ambient. The reason of blue is; it is a color what is making people calm and relaxation to counteract chaos or agitation, to open the flow of communication, to broaden perspective in learning new information, solitude and peace…

What about the technological aspect, Bozca Zest is a high performance eco-friendly car. It has a Full Hybrid - PHEV (plug-in hybrid electric vehicle) propulsion. It has an Audi 5-cylinder turbocharged engine. The combination of direct fuel injection with turbocharging is a logical advance. A 2.5-litre engine capacity delivers a power output of 250 kW at between 5400 and 6500 rpm and 450 Nm of torque at just 1600 rpm coupled with 4 synchronized electric engines. They have permanent magnets with axial flow disc (in-wheel motor) integrated into the wheels. During normal use, the vehicle uses only the electric engines using electric energy from the batteries or from the engine, in case that the batteries are discharged. It is possible thanks to a generator. The latter produces electric energy that is used immediately from the electric engines and it could be stored when it isn’t completely used. The turbo engine isn’t mechanically connected to the wheels and it works with constant torque at minimal consumption regimes. The lightweight is also guaranteed from the absence of the gearbox, clutch and differentials.


The Bozca Zest’s performance is comparable with internal combustion engine sport car. It has a composite chassis the makes the car lightweight, only1200 kg. It permits to achieve high performance, 270 km/h and 0-100km/h in only 5,5 sec. These performances are provided thanks it low aerodynamic body, able to have a 0,35 Cx.

Chassis and body

The chassis is designed to be built with a CFRP chassis in order to be lightweight and really strong to impact. In the front there are carbon fiber conical elements able to absorb impact energy. The energy trunk is also in the front part in order to have progressive shocking absorption. The doors have a carbon fiber wave absorber. The body panels are thought to be realised with natural composite materials. They are a sandwich of linen and cork linked with and epoxy resin matrix. This choice permits to have a safe structural cell and lightweight bodywork. It is also coherent with the project target to design an environment friendly car. The wheels are built with recycled aluminum.


The technology is an important issue onboard of Bozca Zest. The drive is by wire and it is also an important weight reduction while start and stop system helps to save as more energy as possible. The energy onboard is stored in a 84 kg lithium battery pack. It is placed in the middle of the car in order t have a better balanced vehicle. The engine mainly produces the energy but plug-in, during parking, or by a braking energy recovery system and photovoltaic panels on the transparent roof could charge the pack during the march. During high speed running the inverters provide also braking control, traction control and stability control making Zeist one of the most safety car in the market.

I am both very creative, positive minded and very quick to assimilate new skills and ideas. I am very confident in using design and digital modeling programs. In a short time, I achieve high quality results. I have a keen eye for detail and aim for perfection. These skills I have developed through my degrees and various works.

I have completed a number of design projects both during my vacations and as part of my courses that have required me to work as both part of a team and individually. These different projects and experiences have given me a wider insight into design.

In 2010, I started my design career with BST Muhendislik (Turkey) where I worked as a yacht designer in their special powersail yacht project. This taught me first hand how to use Rhinoceros and helped me put my creative imagination to reality. The majority of the powersail was designed by me. Two months later, through Coventry University, I started to work with Aston Martin (UK) in a collaborative conceptual project, which took my skills to higher level. Followed by a futuristic electric car project with Ricardo (UK). I helped them to discover their vision for the future. In 2011, I had a four-month placement with Miss Tor Yacht (Turkey) as a yacht designer & digital modeller. During my final year in Coventry University, I went to Majenta Academy (UK) for 3 months to increase my modeling skills with A-class surface. And then I studied naval architecture and engineering as well at Politecnico di Milano (Italy) to further develop my skills and knowledge.

He has been technical office as a chief in an important engineering company in Modena to where BMW Motorsport committed to design and develop a 1000cc engine and a complete motorbike (800cc and chassis) to participate at the MOTOGP from 2002 to 2007.

He is a young architect and yacht designer. He worked as a team manager in the Powerboat P1 World Championship and he collaborates with technological shipyards where he develops a strong composite materials knowledge.

He is a experienced photographer who awarded two times by National Geographic.
