Baku Grand Prix Tech Updates
With the longest full throttle distance on the calendar (2,010m), the only way to be fast around the streets of Baku is to reduce drag. Therefore, teams arrive with lower downforce packages than what they ran in China, and although these aren’t quite Monza-spec (some downforce is still beneficial around slow speed corners) these packages achieve medium levels of downforce – similar to what the teams run at Spa and Montreal. 
Additional challenges include managing brake temps and tyre temperatures with the long straights cooling the front axle while hard acceleration out of the slow speed corners heats up the rear tyres. So then, there are plenty of tech updates for us to get our teeth into…
The most noticeable change was once again on the Mercedes W10. Although the angle in the below images is slightly different, the two main elements on the W10’s lower downforce wing (top) are clearly much narrower than the higher downforce package run at China (bottom).  Rear wing comparison of the Mercedes W10 between the Baku GP (top) and the Chinese GP (bottom)
Furthermore, the centre of the main top element is much flatter, compared to the aggressive dip seen on the higher downforce wing (highlighted in blue). Also, the bottom element has an unusual serrated top edge.
