It’s often billed as the most popular PlayStation property, but just how big is the Gran Turismo franchise? Speaking during the series’ 15th anniversary event at Silverstone earlier today, Sony Computer Entertainment Europe’s head honcho Jim Ryan revealed that the brand has raced past an extraordinary 70 million units to date, with half of those sales coming from the European region.

The executive also took a moment to confirm that Gran Turismo 5 has now crossed the 10 million units milestone, an impressive feat for such a divisive release. Given the timing of the title, we think that the upcoming Gran Turismo 6 will struggle to achieve a similar figure – well, unless it hits the PlayStation 4 at a later date, anyway.
