Code found in Apple's backend car key system suggests the company is preparing to add support for MG vehicles.

The discovery indicates Apple has begun preparing car key support for SAIC Motor's MG brand. With an Apple Car Key, drivers can use their iPhone or Apple Watch to lock, unlock, and start a compatible vehicle instead of relying on a traditional key fob, with support for Express Mode that works without authentication.

MG began as a British sports car marque in 1924 before China's SAIC Motor acquired the brand in 2007, and it has since become one of the fastest-growing car brands in Europe. The company recently delivered its one millionth car to a European customer, with roughly 386,000 of those sales coming from the UK alone, where MG now holds more than four percent of the market and ranks among the country's 10 largest car makers by volume. That growth has been driven in large part by MG's electric lineup, including the MG4 and MG Cyberster.

As with other backend references to expanded Apple Car Key support, the code does not indicate which MG models will be compatible or provide a timeframe for rollout, and MG has not yet announced support for the feature. Its addition to Apple's backend code does suggest, however, that its release could soon be on the way.
