Lewis Hamilton's Mercedes Formula One team are looking to return to the top of the Grand Prix field in Barcelona with a number of innovative new design features coming on stream in Spain. Gone for this Grand Prix is the experimental longer wheelbase W08, replaced by a slightly shorter version of the car that now carries significantly less weight than at the beginning of the season. Allowing the team a wider scope of setup options and ballast placement in future races, the shorter, lighter car is arguably one of the biggest gains for the Silver Arrows since packing up the silverware from Russia almost two weeks ago. Although impressive in it's gains so far, Mercedes are well aware that further work on the base weight of the car will be required if the team are to retain a competitive advantage over it's nearest rival Ferrari and the rapidly improving Red Bull team. On a slightly more visual note the #44 and #77 AMG Mercedes cars of Lewis Hamilton and Valtteri Bottas also showed up in Spain with some interesting new detailing around the front of the car, with a striking new turning vane running from the middle of the front nose section to beneath the drivers survival cell, plus the inclusion of new bargeboards, revised floor, several new and updated bolt on aerodynamic devices and most telling of all an updated Mercedes Power Unit featuring further strengthening and improved reliability. The question is will these updates be enough to overthrow Ferrari in the drivers championship at the end of the weekend, and can the development pace of big rivals Red Bull and the Italian Prancing Horse match the best work of the boys from Brackley? We will find out for sure at the end of the final lap of the 2017 Spanish Grand Prix in Barcelona this weekend. The 2017 Spanish Grand Prix at Barcelona takes place on the weekend of Sunday 14th May.
