Our vision was to design a car that was built around the needs of urban citizens. 

A car that would elevate all those everyday affairs like commuting, shopping, or dropping the children off at school into an adventure. A car that’s friendly to the community and the environment.

This vision soon became personal. We’ve always admired classic gentleman-style cars, but currently these aren’t seen on city streets in the EU at all.

That inspired us to develop a microcar that would be ultimately attractive, compact, suitable for the city, practical, and fun - all wrapped in a timeless design.

We have decided to design a L7ea2 class, 2 - seater microcar, because we believe it serves the city citizens the best.

● Microcars are advantageous: Urban areas are approaching car-saturation, so city authorities are starting to impose restrictions on large vehicles. In Tubingen (Germany), cars over 1.8 tons face parking fees six-times higher than smaller cars.

● Microcars are efficient: The average distance we drive daily is 35 km, carrying on average only 1.2 people.

● Microcars are environmentally-friendly: Small cars require fewer raw materials in production, so less material needs to be eventually recycled. Being lighter, they also have lower fuel consumption.

● Electric microcars are sustainable: Electric cars have zero local CO2 emissions and need far less energy.

● Microcars are more suitable than motorcycles: Motorcycles have limitations in bad weather and helmets and protective clothing are needed.

A prototype vehicle with an internal combustion engine was built to verify our project feasibility. The required mechanical properties combined with the retro design had to be tested. When creating the 3D design and construction, we designed the rear axle drive with the engine mounted at the rear for a weight distribution of 42:58. This met our aim to achieve stable, comfortable, and fun driving conditions. We were also confident that the legislative limitation of 15 kW of power would not hinder our goal. We want the vehicle to buck all the trends in today’s motoring world. Anyone who loves driving knows that the time when driving was a pleasure are long gone. I don't get the feeling of driving in a modern car, I don't know what to focus on with all the electronic functions. Today's car producers aim to market increasingly autonomous cars where the sensation of speed is dulled. We aim to reverse this trend. We want getting from A to B to stimulate emotion and fun, even at lower speeds.

The results of the test-drives, which we used to verify the mechanical construction (tubular frame), propelled us forward and we worked to complete the chassis design. We applied findings from testing to a 3D model, so that the second prototype served as a pre-production version and saved us valuable development time. This second prototype will have a chassis comprised of composite materials. Our team does everything to ensure that the project moves forward in terms of design, technology, and legislation. Our work receives the first positive results, we have a pre-approved 3D vehicle model that meets homologation requirements in the L7e A2 category. We cooperate with TUV Czech on the vehicle’s homologation – working through details to minimise the unexpected. Some technical parameters will change for sure, since we can incorporate advances in the sector’s development and production processes. Yet we can already state that the stylish design is final.

To achieve optimal results, we’re testing three types of low-voltage e-motors with similar parameters, tuning range, dynamics, and reliability. The resulting technical data parameters may still slightly change, as the PATAK MOTORS team is constantly working on developments with the aim to optimize and improve the vehicle’s technical parameters. The batteries will be located below-floor, and an electric motor will drive the rear axle. No gearbox is required for the given engine type, which saves weight. This is our goal in all vehicle versions. Lower vehicle weight extends usable range, increases dynamics, and improves handling. We’re working on differential tuning with various settings and gear ratios. We aim to achieve higher maximum speed while maintaining sufficient acceleration. We are still testing battery reliability, charging cycles, and seeking to reduce charging times. For the basic battery version (Stage 1), we also plan to enable the use of classic 230 V domestic connection instead of special charging stations. This will enable vehicle charging anywhere.

An experienced team of experts has been working on the project from the outset. We are preparing for production with the support of EVEKTOR, which has numerous successful international projects related to the serial production of aircraft and car design. For the design we also drew on EVEKTOR’s know-how and experience – as also leveraged by major car manufacturers. We continue to welcome cooperation with other successful development and production companies. We plan to start the Rodster’s production process in Slovakia.

After configuring individual vehicles, series production will commence. PATAK MOTORS’ quality department will oversee the whole production process. A condition of the homologation process is ensuring reliable and repeatable production that meets TUV Czech requirements.
