Just like any other car, red tail lamp indicates a warning to the drivers behind when the car is about to slow down. This applies to the dry racing conditions. But the light's important use in F1 is during wet conditions.
The current internal combustion engines also use a turbocharger so that apart from the electrical power boosting the engine from the hybrid system, further power comes from the turbo, which works by taking the hot gases from the engine's exhaust system and uses them to spin a compressor that increases the air and fuel
Since 2009, F1 cars have technically been hybrids because of the KERS, or kinetic energy return system, which uses exhaust to store energy that can add horsepower in short bursts. Over time, F1 regulations on fuel quantity and burn rate have incentivized many more hybrid developments.
1, was initially developed by Flybrid Systems. To harvest the energy upon braking, the system uses the braking energy to turn a flywheel which acts as the reservoir of this energy.
The drag reduction system (or DRS) is a form of driver-adjustable bodywork aimed at reducing aerodynamic drag in order to increase top speed and promote overtaking in motor racing. It is an adjustable rear wing of the car, which moves in response to driver commands. DRS was introduced in Formula One in 2011.
Indy cars are generally considered faster along straight lines. However along road circuits with lots of corners, Formula 1 cars are much more quicker. This is because F1 cars have better brakes and stop much faster than Indy cars as well as F1 cars having much more aerodynamic grip (downforce) than Indy cars.
"Compared to 2014, the power output [in 2019 cars] is 109 horsepower greater using the same amount of fuel," Mercedes has said. On top of that, F1 has numerous rules that limit the way cars can operate. Teams are limited to five engines per car per season, rather than swapping out power units after every race.
F1 engines lose power over time, in somewhat the same fashion as road cars. However, due to the design on F1 engines, the timetable on which this happens is way quicker. F1 engines are designed to give everything they have, for only a few times. The measurements on these engine parts are almost scarily precise.
Fuel : well unlike road cars f1 engines uses spacially desinged fuel by their fuel supplier. Compression ratio : f1 engines have very high compressio ratio which means that the air fuel mixture burns more efficiently hence producing more power from every bit of fuel.
Lower piston speeds means less stress on the connecting rods and crankshaft as well as acceptable flame propagation speeds, allowing the engine to rev even higher. Formula 1 engines and motorcycle engines often have very high bore/stroke ratios, allowing for higher engine speeds (and thus more power).
Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 reciprocating engines. They were introduced in 2014 and have been modified over the past seasons. The power a Formula One engine produces is generated by operating at a very high rotational speed, up to 15,000 revolutions per minute (rpm).
The MGUs send that recovered energy to a lithium-ion battery—up to 2 megajoules each per lap, where it's then used either by the MGU-K to provide a 120kW (160hp) boost to the rear wheels for up to 33 seconds a lap or to spin the turbocharger to improve throttle response.
