Probably every transmission repair specialist was keen on LEGO constructions or at least enjoyed making some minor things with their hands. Here's the game taken to a new level of creativity!

Modern auto industry is full of sophisticated drivetrain technologies which are supposed to make your driving experience even more pleasant and trouble-free. Despite a great abundance of sophisticated technical solutions, it is highly likely that very few people know a transmission solution operating like a manual CVT.

Over recent years engineers developed a lot of gear shifting solutions for different car brands, which may seem a bit unusual for oldtime drivers. In this article we will review the most peculiar gear stick technologies and provide video materials related to these technologies.

Only few people know about transmission concepts which were popular 70-90 years ago. For men of today, these gearboxes may seem very unusual and weird, but even now some gearboxes that date back to those years are quite competitive in comparison with modern transmissions.

Nowadays Extroid CVTs are commonly known as “toroidal” due to the fact that the working surface of driving and driven discs in this transmission has the form of a torus. Extroid CVT is not a V-belt transmission, but a friction drive CVT.

ZF Aftermarket Develops New Clutch Kit and Marks Its Long-Time Presence in Motorsports

ZF Aftermarket has always been devoted to satisfying the needs of its customers by providing innovative and efficient solutions. Under its SACHS brand, ZF Aftermarket has presented an improved clutch kit intended for performance-oriented cars and those operating under severe driving conditions. To demonstrate how engineering concepts are converted into serial products, and to mark the 80-years’ presence in motorsport, the company has invited 3 well-known racing drivers to participate in the new “Brand Ambassador” initiative.

SACHS products developed an outstanding reputation among racing drivers, but as a pacemaker in the area of advancing mobility solutions, ZF frequently readjusts its racing technologies to be applied for manufacturing of components used on road cars worldwide. The new improved SACHS clutch kit brings ZF’s know-hows into everyday life.


Designed particularly for high performance applications, the new kit comprises a clutch pressure plate, clutch disc and release bearing. The range was initially designed for Subaru diesel models with the year of manufacture from 2008 onwards. The reinforced diaphragm spring ensures prolonged operating lifespan and better contact pressure, which enhances robustness of the gearbox and lower friction wear.

The brand has been presented in the racing world since 1937 when the design of the 1-st Mercedes “Silver Arrows” was complemented with SACHS spare parts. SACHS’s products also gained recognition in Le Mans and F-1 competitions. Nowadays, ZF’s collaboration with motorsport is not limited to supply of quality parts, but also includes technical support. Two ZF tech teams travel around the world during the racing season, recalibrating absorbers and fixing clutches. Providing engineering support at racing events around the globe, ZF experts contribute to successful results of teams supported by ZF.
