The DragSim™ is an all-new, state-of-the-art 1/4- and 1/8-mile vehicle dynamics simulation for Windows95/98/Me or Windows2000/XP from the experts at Motion Software (check out customer comments). With unprecedented speed and accuracy, the DragSim allows you to design and "assemble" any car, motorcycle or dragster. Then evaluate its performance through every inch of a simulated drag race. Enter any engine power curve, or test engines you've designed in the DynoSim (you can even test a variety of jet and rocket power plants!). Evaluate gear ratios, shift points, wind, weather, and much more. Instantly view ETs and speeds using a Pop-Up TimeSlip™. Test and compare up to four vehicles at once. Plus, you can use Motion's exclusive Iterative Testing™ to run multiple tests and find the best setups for virtually any performance or racing application, automatically!

Software Overview: The DragSim performs a comprehensive simulation of the physics that act on a vehicle as it accelerates from a standing start to terminal velocity 1/8- or 1/4-mile down the track. This comprehensive analysis predicts and displays vehicle performance, inch-by-inch, throughout the entire race. The display looks similar to a professional data-acquisition system! You'll clearly see exact elapsed times, speeds, rpms, and more for rollout, 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 you locate the best component combinations. And you can do all this without spending a dime on track testing!

User Interface And Features: The DragSim has a completely new user interface built from the ground-up for Windows95/98/Me and WindowsSim/XP. Our eye-popping “XP” look is even easier to use with QuickAccess™ buttons and DirectClick™ menus that let you change parts simply by clicking on any component shown on screen. Nothing could be easier! Analyze engine RPM, Clutch RPM, Acceleration, Tire Slip, Aero Drag, and more, then view the results in full-color graphics. All data and graphs can be printed (and previewed) in color on any Windows printer. You can even model several vehicles at once; just click on a Vehicle Selection Tab to focus on any vehicle you choose.

Even though this program is very sophisticated, the DragSim will never overwhelm you with data. An easy-to-read, 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 in appearance to the paper time slip delivered to racers at the end of a run, you'll find Motion's Pop-Up TimeSlip™ a helpful, at-a-glance feature.

The DragSim also incorporates exclusive technology that helps you find optimum combinations for any vehicle faster and easier than ever before. QuickIterator™ Testing, available only from Motion Software, allows the DragSim "home in" on the best parts combinations for you, automatically! Click just one button and the DragSim perform hundreds, thousands, or even millions of tests! The QuickIterator™ keeps track of all the results, and display the best combination for you to review. Find the setup that delivers the quickest ET or the fastest MPH for any street or racing application.

New ProTools™ Kit: While all essential features are included in the Advanced version of the DragSim, professional builders and serious enthusiasts need all the modeling power they can get. The optional ProTools™ Kit extends the functionality of many DragSim features. It includes the ProIterator™ for fully customizable testing, DataZones™ to give you the most graphing and data analysis power possible, ProData™ that includes a new table of extended vehicle performance data, and ProPrinting™ that prints out a comprehensive test report that can include your name, address, company logo, glossaries, and all ProData™ values. If you're serious about drag racing analysis, consider a ProTools™ addition to the DragSim.

Technical: This sophisticated simulation 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 DragStripSim is as easy as 1, 2, 3. Pop-up menus allow you to enter any engine power curve (also reads DynoSim 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 DragSim is supplied with a full-color, 100+ page, on-disk Users Manual (directly accessible from within the DragSim program) that details the features of this comprehensive simulation.

Requirements: The DragSim runs on any Windows95/98/Me or WindowsSim/XP equipped IBM-compatible PC. A basic VGA video system is required (minimum 800 x 600; 1024 x 768 or greater is recommended). A Windows-compatible printer required for test reports. A CD-ROM is also required. A complete DragSim install requires approximately 120MBytes of disk space.

Availability: The DragSim is available NOW!.
