Tech: Name That Engine Exhaust Sound

V12 engine of a Lamborghini.

Vroom, Vroom!  The familiar rumble of a modified car starting up or revving its engine will usually turn a few heads in the direction of the sound.  For many car enthusiasts, adding a freer flowing exhaust is one way to increase the joy of driving their vehicle.  Being able to hear the exhaust note of the engine helps to facilitate the sensation of sportiness in a vehicle, and to some drivers it is enough to take the place of their radio on drives through back country roads.  Cars come in all sorts of engine configurations, displacement and in either turbocharged, supercharged, or naturally aspirated guise.  In the city you have most likely heard inline 4 cylinders, V6 engines and V8 engines on the road, but some of the other popular configurations are the rotary (Wankel), flat 4 and 6 engines, and inline 6 cylinder engines. 

Technical Look at the Subarota spawn: Toyota 86/Scion FR-S/Subaru BRZ

Courtesy of Mike Kojima from MotoIQ, here is an in-depth look at the new Scion FR-S/Subaru BRZ coming to the U.S. next year.  The vehicle looks to have a solid foundation for tuning enthusiasts and with a few minor modifications, it should prove to be a very rewarding dance partner in the twisty bits of a drive.
