Do you accept videos to be posted on your site?

Yes!  Please email the videos you'd like to be posted with a description and source.  If you cannot email them and do not have a link where we can download them, then let us know and you'll be given an FTP address to upload them to.

Where do you get your performance numbers?

The performance numbers come from the Cartest 2000 computer simulation program.  This java-based application allows you to enter specifications for a vehicle, which is normalizes to perform mathematical acceleration and track simulations.  This application must make several assumptions about power delivery, center of gravity, suspension geometry, etc. so the results may not match real-world numbers exactly.  Every effort has been made by Car-Videos.com to achieve as realistic numbers as possible.  In the rare case that satisfactory numbers cannot be achieved, the model in question is removed from the site.

Why are the performance times wrong?

Lots of research and care have gone into making the performance numbers as accurate as possible.  There are several reasons why the performance numbers may be incorrect:

1) The manufacturer has intentionally or unintentionally published incorrect specifications.  The victims of this are usually horsepower and torque, but sometimes it can be gear ratios, axle ratio, electronic speed limiter, etc.

2) The engine's power curve is flatter or steeper than normal.  BMW engines and the VW/Audi 1.8T are notorious for having very flat power curves.  This results in better performance numbers than typical engines with the same hp and torque ratings.  And Kia engines typically have steeper power curves resulting in worse performance numbers.

3) The simulator shifts too early or too late on a specific change.  This can results in only one or two of the straight-line acceleration numbers not matching other testers' results.  The simulator optimizes gear shifts to achieve the best acceleration numbers over a large distance.  This may cause the car to shift gears just short of an important acceleration time mark.  For instance, 2nd gear in a car may redline at 62 mph, but the power drop-off at high RPM may result in an optimal shift at 58 mph.  The extra 0.3-0.8. seconds required to shift to 3rd gear will increase the 0-60 time by approximately that margin.  In some instances, a note had been added to the bottom of the car's performance indicating this with the performance number(s) that would have been achieved if the gear change was made at or above redline.

If you disagree with the performance numbers of a specific car on the site, please contact us with the name of the car in question.
