"In recent years, major automotive manufacturers have increasingly relied on sophisticated virtual design and development software tools to increase the overall quality of their products while shortening the time to market. It is no coincidence that GTI, which possesses the most technically capable and experienced developers of commercial powertrain software, has seen rapid growth during this same period. GT-SUITE is the logical choice for engine designers seeking to gain the competitive edge that an industry leading, state-of-the-art tool can provide." Dr. Paul Blumberg Former Director of Ford Product Development Information Technology and of Ford Research Laboratories "Innovation has long been a pillar of Renault's overall growth strategy. To maintain this edge in a global market, Renault engineers require design tools that allow for collaboration among engineering groups and technology partners, while shortening time to market. GTI's reputation for customer support excellence, and experience in providing such tools to the world's leading engine makers, including Renault's partner Nissan, makes it a logical choice to assist our company in our development efforts." Dr. Stephan Guilain Gas Exchange Process Team Leader Renault Automobiles "GT-POWER and GT-COOL are integral parts of the design process at BMW.  BMW uses several components of GT-SUITE, and gains productivity benefits from their commonality and integration." Dr. Holger Haas Powertrain Development BMW AG "Your support is really the best I have seen compared to other software producers." Johan Forss Advanced Combustion Engine Development Scania AB "To me, the most impressive characteristic of Gamma Technologies' staff is their response, which is crucial in the world of race car competition.  So far, every request I have had has been satisfied within a very short time.  Also, every new release has demonstrated real improvements, showing how Gamma Technologies' development strives to comply with the customer's needs." Pierre-Jean Tardy Leader of Acoustic and Performance calculations Renault F1 "Engineers at the Mack Truck Powertrain Division have been using GT-POWER since mid 1998.  The software has been utilized for numerous diesel engine development programs and has become integral to our engine performance and emissions analysis.   GT-POWER has been used in the development of cam shaft profiles, intake and exhaust manifold shape and volume, turbocharger matching, engine ECU data file development, cylinder head flow modifications, heat rejection investigations, and numerous engine breathing management studies.  The application of simulation results has greatly reduced Mack's hardware and test iterations during development. Plus, a number of Mack suppliers are currently using GT-POWER.  Sharing model files with these suppliers has enabled more rapid and integrated component development." Joseph Schmidt Mack Trucks "We use GT-POWER as the standard for one-dimensional modelling of fluid dynamics at IC engines.  The range of application reaches from tasks like the design of switch-over intake systems, up to detailed flow analysis by calculation coupled with Star-CD.  The built in database of GT-SUITE gives us the chance to handle a great number of projects efficiently and have direct access to our engine-library.   With direct contact to the developers a quick and excellent support as well as the rapid implementation of new algorithms is guaranteed.  Our opinion: GT-POWER is first choice in 1-D CFD." Prof. Dr.-Ing Michael Bargende FKFS - Universitaet Stuttgart "I have used GT Power with success in several areas of engine design, optimization, analysis and development." Ondrej Tomek GM Racing "Fiat Research Centre has developed the UNIAIR electro-hydraulic Variable Valve Actuation system for throttle-less load control in gasoline engines. Recently this system was applied to the intake and exhaust valves of a 4-valve per cylinder common rail DI Diesel engine in order to allow a wide range of valve actuation strategies aiming to control in-cylinder air and residual gas quantity, swirl level and charge temperature. During the development, GT-POWER was extensively used for the identification of optimised valve lift schedules in full- and part-load conditions. The simulations proved to be very reliable and thus contributed to the reduction of the overall design and experimental workload." Dipl.Ing. Maria Grazia Lisbona Head, Fluid Dynamics and Combustion Analysis Dept. Fiat Research Centre "GT-POWER has given us the capability to develop engine performance models that correlate very well with actual test results. We have used these correlated models to predict future engine performance before the parts have been cut. This has greatly reduced the number of tests in the dyno cell for many of our projects, and has given us more confidence in our design directions." Anthony Coffey Harley Davidson "GTI's GT-SUITE conference is an important event for GM's engine simulation analysts. The event provides information on technical advances from both the software and user perspective. The conference also allows us a chance to compare notes with our automotive and non-automotive peers." Gerry Clark CAE analyst GM Powertrain "Few companies provide the engine modeling technology available in GT-SUITE. GTI's technical capabilities, coupled with their superior support, made our decision to choose GT-POWER an easy one." Suzanne Caulfield Analysis Engineer Briggs&Stratton
