Bruno Senna Lalli (Portuguese pronunciation: [ˈbrunu ˈsenɐ], born 15 October 1983 in São Paulo) is a Brazilian Formula One racing driver and the nephew of the late three-time Formula One world champion Ayrton Senna. His mother is Ayrton's older sister, Viviane. His father, Flávio Lalli, died in a motorcycle crash in 1996. He wears a slightly modified version of his uncle's helmet. Senna made his Formula One début in 2010, driving for Hispania Racing. He moved to Renault in 2011, replacing Nick Heidfeld as a driver from August of that year, and since January 2012 he is signed to the Williams team.

As a child, 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.

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 Formula One Brazilian Grand Prix meeting in São Paulo, at Interlagos, where Ayrton had won in 1991 and 1993.

A race engineer is a motorsport team member whose role is to communicate with the data analyst as well as the mechanics to determine the changes to be made to the vehicle. Off the race track, the race engineer analyzes historical data to determine the initial set up for the next race event. The race engineer function includes hands-on management of the vehicle mechanics, organizing testing schedule, as well as studying the regulations. The race engineer seeks to make all these activities occur as seamlessly as possible for their driver.

In addition, the vehicle set-up must stay within the regulations for the race event. The primary goal of the race engineer is to achieve the best performance from the vehicle and from the driver at the race track.

A good race engineer must have good interpersonal relationship skills. To be effective, the race engineer must have a good working relationship with not only his driver, but also the rest of the team, both at and away from the track. Many times the race engineer is also "the face" of the team for the media; this is especially true during the race while the driver is inaccessible. This makes the race engineers media skills a priority.
