2015 Spanish GP Tech Highlights

Note: This is essentially my analysis piece for Richland F1, with some added bits and pieces, illustrations and details about the fuel flow monitoring changes that were introduced. Exam season is in full swing so apologies for the not-so-exclusive content this week.

Barcelona is pretty much the best playground for an F1 car. Aerodynamics are severely tested with a variety of long, high and medium speed corners spaced out by a series of straights, whilst the final sector is now a good hunting ground for those with strong mechanical grip after the circuit layout changed in 2008.

With such an emphasis on aero, updates are often developed from around the end of the winter testing period specifically for this race and on into the middle of the season. Teams recognise this as an opportunity to jump ahead of their nearest rival but with almost everyone making gains all of the time, eking out that extra tenth of a second from the overall package is all the more crucial.

Analysis: Gear ratio selection

As of the start of the 2014 season, teams must nominate all 8 forward ratios (plus reverse) before the opening round. They then have only one opportunity, should they be willing to take it, to change their ratios during the season. That’s it. No bespoke gearing for each track and no free-spirited changing during a Grand Prix weekend.

Given all the computer, dyno and simulation technology at the F1 teams’ disposal, it’s quite amazing how varied the ratio selection is across the grid. There are some positive and negatives for each solution, but is there an optimum setup?

At the midway point in the season, I’m going to attempt to dissect some of the teams’ gear ratio choices and why, surprisingly, they have not converged to one solution. Continue reading
