DragSim5 Drag-Strip Vehicle-Dynamics Simulation
ProTools™ 1/4- and 1/8-Mile Drag-Race Vehicle Simulation

Test Real Or Simulated Engines In
Various Vehicles On The DragStrip Optimize Shift Points, Gear Ratios!

  DragSim5™ with ProTools™ is an amazingly accurate 1/4- and 1/8-mile vehicle-dynamics simulation for Windows Vista, 7, 8, and 10 (32- and 64-bit) from the experts at Motion Software, Inc. The simulation lets you to design and build any car, motorcycle or dragster and accurately evaluate its performance at simulated dragstrip! Enter any engine power curve, or test engines you've designed in DynoSim or Dynomation (you can even test a variety of jet and rocket power plants!). Test any manual or automatic transmissions, any gear ratios, any vehicle weight, wheelbase, driving style, weather and traction conditions and more! Change components with just a mouse click—drag-race times are instantly updated. A PopUp TimeSlip™ provides an easy-to-read visual summary of overall vehicle performance. Even test and compare multiple vehicles at once!
Includes powerful Iterative Testing™ that runs multiple tests and finds the best gear ratios, shift point, and more for any performance or racing application, automatically! DragSim5 is the most powerful and easy-to-use straight-line vehicle-dynamics simulation available! And it’s fun to use, too!

Software Overview: DragSim5 simulates virtually any Automobile, Dragster, or Motorcycle using front- or rear-wheel drive! The simulation performs a comprehensive analysis of the physics that act on the vehicle as it accelerates from a standing start to terminal velocity over the 1/8- or 1/4-mile. This iterative (repeating, step-by-step) analysis determines vehicle performance for each fraction of an inch throughout the entire race. The results display looks similar to a professional data-acquisition system! You'll clearly see exact elapsed times, speeds, rpms, beginning at rollout to 60 feet, 330 feet, 660 feet (1/8-mile), 1000 feet, and 1320 feet (1/4-mile).  ETs and speeds can be compared with up to four other vehicles to help locate the best component combinations.

User Interface And Features: DragSim5 has a completely unique user interface built from the ground-up to be clear and easy use. You'll find vehicle component parts and specifications on the left side of the screen, and simulation results on the right! Eye-popping graphics are enhanced with QuickAccess™ buttons and DirectClick™ menus that let you change parts simply by clicking on any component. Analyze engine RPM, Clutch RPM, Torque Converter Stall Speed, Acceleration, Tire Slip, Distance, ET, Aero Drag, and much more (detailed below). All data and graphs can be printed (and previewed) in color.

   Even though this program is sophisticated, DragSim5 was carefully designed to be easy to use. For example, a Pop-Up TimeSlip™ provides an instant summary of the performance potential of any vehicle. A quick glance will help you make judgments about gear ratios, shift points, vehicle weight, and it can even help you evaluate traction and wheelspin!. Similar to the paper time slip delivered to racers at the end of a run, the DragSim5 Pop-Up TimeSlip™ is a helpful, at-a-glance analysis of track results.

   DragSim5 also incorporates (Motion-exclusive) technology that helps you find optimum combinations for any vehicle. To start off, the simulation includes a Traction Calculator™ that optimizes tire/track modeling and improves accuracy. A simple button click begins a comprehensive series of hundreds of thousands of calculations to determine the tire/track adhesion model that best simulates read-world conditions. You'll also be amazed by Iterator™ testing built into DragSim5 that lets you "home in" on the best parts combinations, automatically! Click one button and DragSim will perform hundreds, or thousands of drag tests! The Iterator™ keeps track of all the results, and displays the best gear ratios and other parts combinations for you to review. You'll locate the setup that delivers the quickest ET or the fastest MPH for any street or racing application!

ProTools™: Professionals need all the modeling power they can get. The ProTools™ included in DragSim5 extend the functionality of many program features. For example, the ProIterator™ lets you perform fully custom testing, DataZones™ give you the most graphing and data analysis power possible, ProData™ includes a new table of extended vehicle performance data, and ProPrinting™ prints out a comprehensive test report that can include your name, address, custom logo, glossaries, and all ProData™ values. If you're serious about drag racing, the DynoSim5 with ProTools™ was made for you!

Technical (under the hood): DragSim5 simulates the complex physics involved in 1/8- and 1/4-mile drag racing, including the incredible range of forces that act on automobiles, dragsters, or motorcycles at the starting line. But you can leave your physics books on the shelf, because the DragSim5 makes complex vehicle analysis as easy as 1, 2, 3. Pop-up menus allow you to enter any engine power curve (also import DynoSim6 and Dynomation6 and other engine files). You can even test jet or rocket power plants! Then choose vehicle components from simple drop-down menus or enter custom specs for automatic or manual transmissions, torque converter stall-speed, launch rpm, shift rpms, up to six transmission gears with virtually any gear ratios, rear-axle ratios, vehicle weight, wheelbase, front- or rear-wheel drive, frontal area, aero drag, tire width, rollout distance, ambient temperature, humidity, wind speed, and more! Internal "watchdogs" eliminate conflicting choices (like an rpm redline rpm set lower than a shift rpm, etc.), ensuring accurate performance predictions.

Users Manual: The DragSim5 is supplied with a full-color on-disk Users Manual (directly accessible from within the program) that details the features of this comprehensive simulation. If you wish, you can download a copy of this manual to preview the capabilities of this software before you buy (link provided at top of this page).

Requirements: DragSim5 runs on any Windows Vista or Win7, 8 or 10 equipped PC. A video display of 1024 x 768 resolution or greater is recommended. A Windows-compatible printer is required for test reports.
