The letter sent to customers
The news has been revealed in a letter from company MD Antony Sheriff to existing owners, offering a free power upgrade for their cars. While McLaren is at it, it will also add a few features to the car, including a remote-opening passenger door and tweaks to the sound system.
The latest upgrade will be available from October 2012 and, for those getting it retro-fitted, Sheriff says coyly that "in order to minimise the time you spend apart from your 12C, we plan to deliver this upgrade package at the same time as we update your IRIS system". For that, read 'we will actually make the sat-nav work...'.
McLaren won't tell us anything more about the changes yet, but promises that full details of the upgrades will be coming soon.
