Just what they needed 
Good thing I didn't buy that 2012:wink:

The most significant update, at least to us, is an additional 25 hp for the MP4-12C’s twin-turbocharged, 3.8-liter V-8. The power increase will come by way of an engine-computer update, bringing the power total to 618 hp. McLaren also is modifying the car’s transmission programming and adding software to allow drivers to alter the level of engine noise entering the cabin. The current MP4-12C has a valved sound tube that pipes intake noise into the cabin at different levels, depending on which driving mode is selected. Now, McLaren owners will be able to adjust the valve independently of the driving mode. Full loud? Yes, please.
Among the less sexy—but still useful—updates is the addition of Bluetooth and navigation functionality for the MP4-12C’s touch-screen–based infotainment system. (The 2012 car had the hardware to support both nav and Bluetooth, but the software wasn’t ready until now.) McLaren also is adding an optional suspension lift mode, which can raise both the front and rear of the car at low speeds. This should prove useful to customers who occasionally are confronted by a steep driveway or rough road. Finally, the MP4-12C’s radio antenna was tweaked for enhanced reception.
