BMW i8 Autocross Video

APR 11 2015 BY ELECTRICCARSTV 3

In the hands of an inexperienced autocrosser, the BMW i8 still seems extremely capable of carving the turns and weaving in and out of the cones.

BMW i8 at GCAC. – Driver’s first-ever autocross.

States the video description.

GCAC?  Hmm…probably not any of these:

Acronym – Definition

GCAC Gulf Coast Athletic Conference
GCAC Greater Columbus Arts Council
GCAC Generic Connection Admission Control
GCAC Garde Côtière Auxiliaire Canadienne (French: Canadian Coast Guard Auxiliary)
GCAC Generic Call Admission Control (Sprint-ATM)
GCAC Genoa City Athletic Club (The Young and the Restless; TV daytime drama)
GCAC Glacier Country Avalanche Center, Inc. (Montana)
GCAC Glaucoma Crónico de Ángulo Cerrado
GCAC Greater Capital Area Chapter of the American Nurses Association (California)
GCAC Gold Coast Arts Center (Australia)
GCAC Global Connection Admission Control
GCAC Gwynedd and Clwyd Association of Craftworkers (UK)

For those who like to hear some exhaust roar, the BMW i8 doesn’t disappoint, even though it’s largely fake.

Would love to see how a Model S does on the same course.

Since the back of the helmet says “Gulf Coast”, I would assume GCAC is Gulf Coast Auto Cross. But that’s just my keen sense of deductive reasoning. http://gulfcoastautocrossers.com/

Well, since the camera is outside the car what you’re hearing is the unaltered actual engine and exhaust note. Not the enhanced noise. So that statement about it being fake is incorrect.

Also, fake is an inaccurate description of the engine note tuning. Historically, all car manufactures spent millions tuning the sound of their cars using mechanical tricks.

Current technology just make it possible to do it digitally. Despite what people believe, you’re not hearing engine sound recordings. The technology is basically the inverse of noise cancelation. Instead of monitoring for certain frequencies and canceling them out with 180 deg out of phase signals, enhanced engine noise identifies where certain frequencies are lacking and adds the signal back.
