\f0\fs24 \cf0 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 \'93tea-tray\'94 splitter off ground during braking\
----------------------------------------------\
NOSE CONE\
\
Article 3\
\
60,000mm2 20,000mm2 9,000mm2 220mm 135mm\
\
\'93Tea tray\'94  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 \'93tokens\'94: 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)\
