BMW i8 artificially made to sound like a V8

Snapshot: BMW adds Active Sound Design system to make it sound like a V8

Sitting in an over-300 BHP hybrid sports car in silence can be discomforting, unnerving and a bit of a let down. So the clever engineers at BMW have come up with an innovative solution – Active Sound Design (ASD) system in the i8. Recently, a video surfaced over the web showing a 0-130 kmph acceleration of BMW i8 and more importantly, the artificial engine sound which i8 produces through ASD to satisfy your V8 soundtrack cravings.

BMW i8 Acceleration

ASD system was first introduced in 2011 on M5 that works in sync with car audio speakers through an electronically controlled module. The ASD generates sound like a V8 and adjusts the base and loudness as the driver switches driving modes between Eco, Sport and Sport+. It can also be turned off completely for silence. Two exhaust pipes are installed in the i8, of which one is a real one for the petrol motor, whilst the other has a speaker to emit sounds while driving in electric mode to make passers-by aware.

The i8 is powered by a 1.5-litre, 3-cylinder, turbocharged petrol engine, producing 228 BHP and a 128 BHP electric motor that in combination deliver 362 BHP to all four wheels, making it capable of 0-100 kmph in 4.4 seconds. And the noise? Well that’s the future apparently…
