We've spied the 2014 Subaru BRZ STI testing in various stages of development, but now we have confirmation it's coming soon. Two teaser images of the car were posted to the Subaru Technica International website, though both teaser images were named BRZ tS teaser, suggesting this might not actually be the fully-fledged STI model we've been longing for. The tS moniker might mean it's simply a BRZ tuned by STI.

The drip tease continues with the 2015 Acura NSX, though instead of yet another concept, Acura has given us a look at a running prototype racing around a track. You can hear the V-6 hybrid powertrain revving hard through the powerband, and it sounds good.

Is Ford going to bring back the Mustang SVO for 2015? It's possible, as a four-cylinder EcoBoost-powered 2015 Mustang prototype was recently spied pulling out of a parking lot. You can hear the turbocharged four-cylinder engine rev as the driver floors the accelerator pedal.
