Audi says it is ditching cow skins in favour of bull hides for its leather upholstery.
The firm claims this is because bull leather guarantees a higher level of consistency.
It says hides from cows are too small and not as consistent in quality and condition when compared with those of bulls.
Audi says it will use bull back hides for areas where a smooth appearance and high robustness are important, such as head restraints, the shoulder area, lower seat squabs and side bolsters.
Around 40 per cent of Audi customers specify a leather interior.
