V-tech Dynamometers - Chassis Dynamometers Manufacturer

For almost 20 years, Vtechdyno has manufactured chassis dynamometers (rolling roads, dynos) for cars, motorcycles, trucks and tractors. There are hundreds of our dynos installed Worldwide. Now our extra-grip rollers are ready for the era of electric vehicles. Our sales centres and showrooms with state of the art AWD dynos are in the UK, Germany and Poland.

Last Expo/Fairs

Our stand at Professional Motorsport World Expo in Cologne with a new EV+ chassis dynamometer, designed for the era of electric cars was shown.
AWD and 2WD dynamometers have enormous traction thanks to a new, bi-prismatic knurling design.
Electric cars have high torque, available from low rpm, demanding dynamometer traction capabilities to be enhanced.
We did it.

How to Choose a Good Dyno

Which dyno to buy? How to choose the right one.

A modular dynamometer (Vtech Dyno PRO and EV+) means no need to buy an AWD dyno at once.

Be smart, think clever! Let your dynamometer pay off itself!

You can have a front module without electromagnetic brakes and buy brakes, AWD extension and additional sensors later. Thanks to the fully modular design, everything is expandable.

The PRO and EV+ VT2/VT4 modular chassis dynamometer series have been present on the European market for more than a decade. The first rolling road was created and installed in 1999, and from the very beginning, it featured an exceptional accuracy of measurement and reliability. During the following years, we developed and improved our chassis dynos (rolling roads) have been steadily, significantly widening the product range. Today's variants of our dynamometers include modular one axle dynamometer and AWD chassis dynamometer (4x4 vehicles). As standard, all have special knurling (PRO models: Ultra-Grip knurling, EV+ models: bi-prismatic TractionBoost knurling). New TractionBoost knurling enables safe and precise measuring high torque performance Tesla, Porsche Taycan etc., or supercars. Multiple models, configurations and options of chassis dynamometer product line are available.

Our dynamometers are available in both inertial and braked versions. Additionally, in the 4x4 version, we use a novelty system of mechanical synchronisation of front and rear axles, which allows measuring the most modern cars equipped with active traction control systems. Also, a dynamometer for motorcycles and quads, RVs and buggy's is available.

We manufacture CE labelled dynos built according to the applicable European standards.

Features distinguishing our chassis dynamometers from competitive solutions:

  • Amazing accuracy – up to 3000 real measurement points per second, relative accuracy below 0.1% (based on the proprietary technology TrueForce II). It is the highest possible performance.
  • Ready for 21-st Century - special Ultra-Grip or TractionBoost bi-prismatic knurled rollers are perfect for high torque electric and hybrid cars. No slipping.
  • Modularity - you can buy an inertial dyno, add an eddy current brake, a motorcycle unit, additional sensors. You can even have four eddy current brakes - up to 2000 HP! Maybe you want to measure 1000 HP monsters, Porsche Taycan or Tesla Plaid?
  • Full 1:1 mechanical synchronisation of axles in 4x4 dynos - you can measure vehicles with advanced systems of traction control and with an active central differential. And more - switch it on and off by your smartphone, or control panel.
  • Full 1:1 mechanical synchronisation of axles in 4x4 dynos - you can measure vehicles with advanced systems of traction control and with an active central differential. And more - switch it on and off with your smartphone or control panel.
  • The dynos have all certificates. Their installation and use are entirely compliant with the applicable regulations, and any external inspection will find everything in order.
  • They are selected by rally and racing teams, tuners and services all over Europe, from Spain to Russia, from Norway to Greece.
  • Rolling roads produced by tuners for tuners – resulting in complete ease of handling.
  • Dynos have the full support of our service and many years of warranty, plus you can have the possibility to extend the warranty time.
  • Multiple configurations and options of dynamometers are available for sale.
  • The software upgrade is free if we service the dyno.

Rolls comparison

Many popular chassis dynamometers manufacturers use lightweight painted rolls or cover them with adhesive glue & sand. Such rolls got worn quickly and never (new or worn) offers good friction, and they look unsightly in general.

Some others use sanding or similar processes. Better, but not ideal.

Our solution is different – we emboss unique tread (with high mechanical pressure). This tread is 3D and CAD/CAM-optimized and can be described as teeth-shaped lines embossed in the roll (see picture). Each "line" has two "tops" across the roller (instead of a standard method of milling them and thus – having only one pinnacle per line) to double the number of contacts to tire. Then, between both "tops", there are micro-cuts (at a right angle to teeth shaped line) to stop the tire from flattening the tread.

For EV+ dyno, we have prepared a new, vastly improved design of knurling called TractionBoost. It uses bi-prismatic tread to prepare dyno for the era of electric cars.

The tire cannot move while contacting the roller. Both directions - thus - less heat. Do you know any better technology?

Finally, rolls are covered with a unique double-layer chromium cover to protect them from being worn. Even ten years of use will not kill their parameters and brilliant aesthetics. Your dyno will always attract the eye of customers.

Tire runs silent, with perfect friction, even with wet tires!

Besides that, larger diameter and heavy rolls we produce better replicate the road conditions that tires are designed to run on and are generally safer.
