Formula One entered its second turbocharged era in 2014. Australia was the location of the end of the first era (Adelaide 1988) and start of the second (Melbourne 2014). The series is being run under the most radical engine regulation changes since 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 kg/hr. New car regulations will also be enforced, and the minimum weight regulations will be raised from 642 kg (1,415 lb) to 690 kg (1,521 lb). Ferrari, Mercedes and Renault produced engines from 2014 with 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 bhp (the previous V8s produce approximately 750 hp); but the new energy recovery system (ERS) would be twice as powerful as the previous KERS system; this new ERS system would give the drivers up to the equivalent of 160 hp when activated, whereas the previous KERS gave cars an extra 80 hp when activated. Since 2017 new rules about aerodynamics and the consistent improvement of the engines, that now reach around 1000hp, have made the cars finally faster than the 2004 ones, breaking numerous track records.
