Dear Mr. Hirai: This is in response to your letter of October 18, 1974, in which yo ask whether you must supply consumer information concerning a vehicle whose motor is modified by a high-altitude kit. Further, you wish to know whether the acceleration and passing ability tests required by the regulation must be carried out at the barometric pressure required by section 575.106(d)(1)(vi).; It is our view that you must submit consumer information that meets al the requirements of Part 575, including those relating to barometric pressure, as they apply to these vehicles. Nonetheless, this does not prohibit your also including, separate from the required information, the performance characteristics of the vehicle at the altitude for which it has been modified. While we are aware that vehicles modified for high-altitude performance might not initially be sold at low altitudes, the highly mobile nature of automobile use makes it appropriate that owners be aware of their performance at the lower altitudes at which many of them will be driven and sold after their first purchase.; Yours truly, Richard B. Dyson, Acting Chief Counsel
