#EngineSounds

With a twist of the key or poke of its start button your vehicle’s engine should fire up with the urgency of a physician responding to a code blue.

Gentlemen, start your felines. In a hilarious marketing campaign, the developers behind the XLR8 app that makes acceleration noises as you drive, strapped an iPhone to their kitty and sent it running.

Have you always wanted a muscle car or exotic but budget and necessity mean you end up driving a compact or minivan? Well, 2XL Games has a solution, namely in its XLR8 smart phone app.

By downloading it your smart phone, XLR8, reproduces the sounds your vehicle’s engine makes under acceleration, cornering and braking but with a twist. Instead of a buzzy four cylinder, the exhaust note sounds like a muscular V8 running a high-lift cam and open exhaust, perfectly matched to your car’s acceleration, cornering and braking.

It does this via accelerometers and a GPS system inside your iPhone, Android or other portable device. By hooking up the phone to your vehicle’s sound system in much the same way as a MP3, simply choose the app and press the button.
