Formula One entered its second turbocharged era in [[2014 Formula One World Championship|2014]]. Australia was the location of the end of the first era ([[1988 Australian Grand Prix|Adelaide 1988]]) and start of the second ([[2014 Australian Grand Prix|Melbourne 2014]]). The series is being run under the most radical engine regulation changes since [[1995 Formula One World Championship|1995]]. All cars entering any Formula One championship race must run with 1.6-litre single turbocharged 6-cylinder engines with a rev limit of 15,000 rpm and maximum fuel flow of 100&nbsp;kg/hr. New car regulations will also be enforced, and the minimum weight regulations will be raised from 642&nbsp;kg (1,415&nbsp;lb) to 690&nbsp;kg (1,521&nbsp;lb). [[Scuderia Ferrari|Ferrari]], [[Mercedes-Benz in Formula One|Mercedes]] and [[Renault in Formula One|Renault]] produced engines from 2014 with [[Honda in Formula One|Honda]] producing engines from 2015; Cosworth did not participate from 2014 and beyond. In-season engine development returned; the previous V8's development was frozen. The new turbo engines produce 600&nbsp;bhp (the previous V8s produce approximately 750&nbsp;hp); but the new energy recovery system (ERS) would be twice as powerful as the previous [[kinetic energy recovery system|KERS]] system; this new ERS system would give the drivers up to the equivalent of 160&nbsp;hp when activated, whereas the previous KERS gave cars an extra 80&nbsp;hp when activated.<ref>{{cite web|url=http://www.formula1.com/inside_f1/rules_and_regulations/sporting_regulations/8689/fia.html|title=Inside F1|work=Formula1.com|access-date=1 May 2016}}</ref> Since 2017 new rules about aerodynamics and the consistent improvement of the engines, that now reach around 1000&nbsp;hp, have made the cars finally faster than the 2004 ones, breaking numerous track records.

The Mercedes team and their drivers [[Lewis Hamilton]] and [[Nico Rosberg]] dominated the start of the hybrid era, winning 51 of the 59 races (31 for Hamilton and 20 for Rosberg) between 2014 and [[2016 Formula One World Championship|2016]] as well as all titles during that period (Hamilton was champion in 2014 and [[2015 Formula One World Championship|2015]] while Rosberg won in 2016). This success was the result of Mercedes' development of the "split turbocharger", a system in which the compressor and turbine components of the turbo charger are placed at separate sides of the engine and connected by a rod running through the V of the engine. This new technology gave Mercedes and their customer teams many advantages over their competitors due to the need for less cooling and a more compact power unit.

Ferrari and their driver Sebastian Vettel emerged as strong title contenders in [[2017 Formula One World Championship|2017]] and [[2018 Formula One World Championship|2018]] after rule changes in aerodynamic design were implemented for 2017, but despite mid-season championship leads for Vettel in both seasons, Hamilton and Mercedes ultimately won the titles with multiple races to spare. Mercedes subsequently won both championships comfortably in [[2019 Formula One World Championship|2019]] and [[2020 Formula One World Championship|2020]] along with an additional constructors' title in 2021, with Hamilton managing to equal Michael Schumacher's record of seven World Championships. In [[2021 Formula One World Championship|2021]], Mercedes faced stiff competition from the Honda-powered Red Bull team, whose driver [[Max Verstappen]] won the Drivers' Championship after a season-long battle with Hamilton to end the run of Mercedes only winning titles in the hybrid era.
