AMCI Testing Certified Test-By-Test Results

AMCI Testing Certification Overview

AMCI Testing’s Certification protocol is based on the statistical imperative for unbiased, repeatable results:
  • AMCI Testing Certified performance is a multiple-driver average of each vehicle’s fastest laps within a window of repeatability
  • Handling was the focus of our track test; as such, we chose a highly technical configuration at Streets of Willow Springs
  • Streets Of Willow Springs lap times were an eight-lap average—not a single lap
  • More than 175 total laps were run to calculate each car’s window of repeatability and optimize electronic vehicle settings. All available configurations were tested and then set to provide the best performance for each vehicle. All cars were run with Electronic Stability Control off
  • Toyota Motor North America supplied a zero-mile, production-conforming GR Supra for this test. AMCI Testing obtained the BMW M2 Competition and Porsche Cayman PDK new from authorized dealers
  • All vehicles underwent AMCI Testing’s break-in procedure. All vehicles had 2,000 break-in miles at the start of the track test, and were broken-in per manufacturers’ recommendations
  • Track testing was conducted on new, scrubbed, OE tires
