The filly missed most of the season after falling in a training accident and injuring her back so severely that she was confined to her box for six weeks.
[3] In the 1000 Guineas at Newmarket less than two weeks later, Carrozza started favourite at odds of 4/1 and finished fourth of the twenty runners behind Rose Royale, Sensualita and Angelet.
[5] Piggott sent Carrozza into the lead a furlong from the finish and looked set for a comfortable win until the Irish-trained grey Silken Glider emerged with a late challenge.
Carrozza was led into the winner's circle by her owner: the filly was initially reluctant but acquiesced after the Queen gave the lead strap a "mighty jerk".
[7] Later in the year, Silken Glider was successful in the Irish Oaks, while Rose Royale won the Prix du Moulin and the Champion Stakes.
