CIMA Transaxle Transmission: the technology that redefines hypercar performance
In the hypercar sector, where every detail makes a difference, the transmission is a central element in ensuring top-level performance. CIMA offers two versions of its transaxle transmission: a first version with 6-speeds, which can be used in manual mode with an H-pattern or in sequential mode, ideal for those seeking a sportier driving experience. There’s also a second version with 7 speeds, available in both AMT configuration, for hydro/electronic automatic gear shifts, and MT, for those who prefer full manual control.
As a testament to its commitment to innovation, CIMA has introduced the CIMA gearbox device in its 7-speed gearbox, designed to optimize gearshift efficiency and smoothness, taking transmission technology to a new level of excellence.
The choice of prestigious hypercars
CIMA is not just a supplier of transmissions but a trusted partner for some of the world's most renowned hypercar manufacturers. Companies like, De Tomaso, Glickenhaus, Hennessey, Nilu27, and many others have chosen CIMA gearboxes for their vehicles, familiar with the level of excellence these systems guarantee.
A significant example is the Hennessey Venom F5, which in 2024 claimed the title of the fastest car in the world, reaching a top speed of 484 km/h. This record, like the previous ones in 2020 and 2021, highlights CIMA’s transmissions' ability to operate at the highest levels, demonstrating how the integration of the CIMA gearbox and the 7-speed gearbox has contributed to achieving extraordinary performance.
The SuperSyncro: advanced technology for faster gear shifts
The SuperSyncro is the core of CIMA’s innovation. This device, specifically developed and patented for the 7-speed gearbox, synchronizes gear changes faster and more precisely. Thanks to a centralized mechanism, the CIMA gearbox reduces upshifting times, ensuring smoother transitions between gears. This allows the vehicle to maintain a constant speed without power loss, enhancing the driving experience during intense acceleration.
The concept behind the SuperSyncro is to improve synchronizer speed alignment, reducing component wear and increasing gearbox efficiency. The result is a system that immediately responds to the driver's inputs, offering a more precise and responsive ride.
Customizable performance
One of the greatest strengths of CIMA solutions is the ability to customize each transmission to the specific needs of the vehicle and the manufacturer. The versatility of the 7-speed gearbox, combined with the CIMA gearbox device, offers hypercar manufacturers extensive configuration options, ensuring that every transmission system is perfectly calibrated for maximum performance.
This level of customization also extends to the final drive ratio, which is tailor-made based on the customer’s requests, enabling optimal power transfer and reducing mechanical losses. Thanks to this flexibility, vehicles equipped with CIMA transmissions can fully exploit the engine's potential, improving power distribution and overall efficiency.
Durability and reliability over time
Hypercars are designed to push the limits of speed and power, often operating in extreme conditions. In this context, the transmission plays a key role, and the durability of the gearbox is essential to ensure that the vehicle can maintain high performance over the long term.
CIMA has designed its gearbox with lightweight, durable materials, similar to those used in racing, ensuring that the transmission is not only efficient but also extremely enduring. The CIMA gearbox, with its ability to reduce component wear, helps extend the gearbox’s lifespan, making it a reliable solution for hypercar manufacturers that require consistent quality and performance over time.
Optimizing weight distribution and torque transmission
Another key aspect of CIMA’s transaxle transmission is its ability to improve the vehicle's weight distribution, which is essential for maximizing traction. By combining the gearbox and differential into a single compact unit, CIMA’s transaxle transmission balances the vehicle’s weight, enhancing grip and handling, especially when rounding corners.
Additionally, CIMA has introduced a torque-sensitive differential, which autonomously adjusts the locking factor based on ground adhesion. This system allows the transmission of higher torque compared to competitors, ensuring exceptional acceleration while maintaining vehicle control even under heavy loads.
Lightweight transmission for optimal performance
Another distinguishing feature of the CIMA transmission is the use of advanced, lightweight materials that reduce the overall weight of the gearbox without compromising power. This not only lowers the vehicle's center of gravity, improving stability and agility, but also improves fuel efficiency by reducing energy consumption, making the car perform better in all aspects.
The future of hypercars
In a market where competition is increasingly fierce and hypercar manufacturers are constantly seeking solutions to push the boundaries of technology, CIMA stands out as a leader in transmission innovation. The CIMA gearbox device, integrated into the 7-speed gearbox, represents a breakthrough in power management and gearshift smoothness, enhancing both performance and durability.
Thanks to a combination of high customization, advanced materials, and innovative engineering solutions, CIMA offers hypercar manufacturers a transmission capable of elevating performance to extraordinary levels, while ensuring reliability and longevity. The CIMA transmission is not just a component: it is the heart of every successful hypercar's performance.
