Electric cars have broken into the market without any conventions. They are there and that's the way it is. Hundreds or even thousands of newton metres of torque have become a reality. Whereas previously these parameters were reserved for dragsters, today a BMW i3 or an Audi e-Tron can burn a tyre on a dynamometer.

Besides changes and new features in new dyno software, our latest version includes "forced coast-down" controlled by eddy-current brake and calibrated via tensometer. It vastly speeds up measurements.

All VtechDyno 4wd (4x4) dynos have full front to rear synchronization as standard. This means that front and rear rolls rotate with exactly the same speed (of course only if sync axles, so called „synchronization” is enabled). Such linked axles functionality is offered usually as option by other dyno manufacturers, or is not available at all. The question is: is such synchronization important for nowadays cars?

As new, modern modular rolling roads may be expensive, especially at the beginning of a new business, used dynos for sale are listed in various internet pages. There are some better and worse developed dynamometers, but in most cases the whole idea of chassis dyno is common – a steel crate with rollers, sometimes twin-rollers. 4Wd (4x4) dynos may have front axle connected to rear with the belt or drive shaft, but most older dynos have no front-to-rear connection and are intended to stabilize and equalize roller speeds with electromagnetic brakes.
