Bruno Senna Lalli (Portuguese pronunciation: [ˈbrunu ˈsenɐ], born 15 October 1983) is a Brazilian professional racing driver currently racing for Aston Martin in the FIA World Endurance Championship. He is the nephew of the late Ayrton Senna, three-time Formula One world champion. Senna raced in Formula One from 2010–12. He made his début driving for Hispania Racing in 2010, raced for Renault from August 2011 as a replacement for Nick Heidfeld, and drove for the Williams team in 2012. Between 2014–16, he drove for Mahindra Racing in Formula E. His mother is Ayrton's older sister, Viviane. His father, Flávio Lalli, died in a motorcycle crash in 1996. The colour scheme of Bruno's helmet is a slightly modified version of that used by his uncle Ayrton Senna.
Born in São Paulo, he was first taught the skills of motor racing by his grandfather Milton da Silva at the age of five. Bruno raced go-karts against Ayrton on the family farm, and Ayrton regarded his nephew's potential very highly. When leaving McLaren at the end of 1993, Ayrton said: "If you think I'm fast, just wait until you see my nephew Bruno". Ayrton's death while driving a Williams at the 1994 San Marino Grand Prix, however, brought Bruno's own racing career to an abrupt halt. Despite these setbacks including the death of his father in a motorbike accident in 1996, Senna's mother Viviane had reluctantly backed her son's interest in motor racing.
At Imola in 2004, however, on the 10th anniversary of his uncle's death, Senna was given an example of his uncle's 1986 Lotus 98T as a gift from an Italian friend. Senna drove the car at the 2004 Brazilian Grand Prix meeting in São Paulo, at Interlagos, where Ayrton had won in 1991 and 1993. Ayrton's McLaren team mate from 1990 to 1992, Gerhard Berger is a close friend of the Senna family and has advised Senna on his career. Senna's sister, Bianca, meanwhile, has managed his affairs and sponsorship acquisition.
