Key F1 technical changes for 2015 A redesigned nose cone is the most noticeable alteration to Formula 1 cars this year, as the usual slew of new technical regulations, designed to push teams to their limits, come into effect -------------------------------------------------- AERODYNAMICS More complex rear diffusers with less intrusion from boat-tail centre section More vanes separating volume of air under rear of car Car weight (without fuel): Not less than 702kg Sidepods: Winglets to reduce lift created over top of sidepods, which cuts downforce Scuderia Toro Rosso STR10 2015 car Suspension: Mandatory use of titanium skid blocks, that wear away quickly, requires hydraulics optimised to keep front “tea-tray” splitter off ground during braking ---------------------------------------------- NOSE CONE Article 3 60,000mm2 20,000mm2 9,000mm2 220mm 135mm “Tea tray” Reference plane --------------------------------------------- POWER UNIT Scuderia Toro Rosso 2014 powertrain Strict rules on height and dimensions of nose, from chassis bulkhead to tip, will ensure more pleasing aesthetics but also improved safety Rule requiring minimum cross section of 9,000 sq mm, between 135mm and 220mm above track will cut downforce and stop airflow beneath car to rear diffuser Development “tokens”: Different areas of engine given value of up to three tokens each. Teams permitted to modify engine up to total spend of 32 tokens Article 5 Turbocharger Internal combustion V6 engine Engines: Four per driver instead of five. Expected to use 2014 model for first few races, while 2015 engines developed further Split turbos: Larger compressors mounted at front of engine expected, for more power from engine Movable inlet trumpets: Increase airflow into cylinders ----------------------------------------- BRAKES Article 11 Carbon- carbon disk and pads Disk must rotate at same speed as wheels -------------------------------------------- NOSE CONTROVERSY Tightening of rules on unusual designs will stop teams trying to get round regulations, as in 2014 Anteater (McLaren) Letterbox (Ferrari) Keel (Redbull) Tusks (Lotus) --------------------------------------------- Source: FIA Pictures: Scuderia Toro Rosso words 310
