MOUNTAIN VIEW, Calif., May 27, 2015 /PRNewswire/ -- Based on its recent analysis of test systems in the automotive market, Frost & Sullivan recognizes Rototest International (Rototest) with the 2015 Global Frost & Sullivan Award for Product Leadership. Frost & Sullivan expects Rototest's hub-coupled dynamometer to become the industry standard as it delivers unrivaled flexibility, scalability, ease of use and effective integration with other test systems in the automotive testing market. Its added benefits of enhanced operational safety, higher productivity, and substantially lower service costs give it an edge against conventional roller dynamometer systems.

Since its inception in the 1980s, Rototest's hub-type dynamometer has stood out for its higher quality and reliability compared to roller dynamometers. Despite offering effective measurement of key vehicle parameters, Rototest's dynamometers have fewer mechanical components, which translate to lower installation, maintenance and service costs. Original equipment manufacturers (OEMs) such as Fiat and General Motors (GM) have acclaimed Rototest's dynamometers for their impressive accuracy and dependability.

A significant advantage of the hub-type dynamometer is its flexibility and scalability. Rototest's dynamometer allows users to test complete vehicles, vehicle powertrain, or powertrain components on the same system, which otherwise would require a roller-type dynamometer, a drivetrain test rig, and a component test bed.

"The innovative hub-type dynamometer design offers many advantages over conventional dynamometers, as it is directly connected to the hub of the vehicle or the object being tested, instead of the tires," said Frost & Sullivan Research Analyst Apoorva Ravikrishnan. "It is sleek and weighs less than roller-type dynamometers, thus providing superior ease of use."

Furthermore, the infrastructure changes required for the hub-coupled dynamometer's setup are minimal. Unlike the conventional dynamometer that requires a moving floor setup, the hub type uses a flat floor setup. Besides, a conventional roller-type dynamometer's surface has to be refurbished as part of a continuous maintenance program and the in-ground installation makes this refurbishment complex, time-consuming, and expensive. Rototest's hub-type dynamometer's innovative design, on the other hand, eliminates continuous wear and tear. It also supports the efficient and safe change of steering angles under load, thus improving safety.

"Rototest's product helps achieve a stable test environment because of the coil-over shock absorbers. Run-out can be kept at absolute minimum with its high precision wheel adapters and adapter hubs," observed Ravikrishnan. "Owing to the system's high sensitivity, individual engineering changes can be precisely quantified and their contribution to the greater efficiency of the powertrain determined quickly and effortlessly."

Meanwhile, Rototest is involved in many brand-building activities, such as expanding its contact network globally, which, ultimately, is widening its presence in the test systems market. Automotive OEMs are becoming increasingly aware of Rototest's product, and they find that it delivers industry-best reliability, quality, and flexibility.

Overall, the design of Rototest's system is far more advanced than any of its peers', which makes the company worthy of the 2015 Global Frost & Sullivan Award for Product Leadership.

Each year, Frost & Sullivan presents this award to the company that has developed a product with innovative features and functionality, gaining rapid acceptance in the market. The award recognizes the quality of the solution and the customer value enhancements it enables.

Frost & Sullivan's Best Practices Awards recognize companies in a variety of regional and global markets for outstanding achievement in areas such as leadership, technological innovation, customer service, and product development. Industry analysts compare market participants and measure performance through in-depth interviews, analysis, and extensive secondary research.
