Essential changes of 2014 Formula 1 season

Published

on

Renault has unveiled its 2014 turbocharged Formula 1 engine 32014 Formula One season will fetch several huge modifications in the technical system; the vital change is F1 take up new 1.6-litre turbocharged V6 engines. Other some changes in aerodynamics and a far greater emphasis on energy recovery systems (KERS).

Engine – it’s out with 2.4-litre normally-aspirated V8 engines and in with 1.6-litre V6 turbo engines, revving to a maximum of 15,000rpm. The current engines produce more than 750bhp, whilst the 2014 units will produce around 600bhp with additional power coming from Energy Recovery Systems (see below).

Gearbox – gearboxes are to have eight forward ratios – rather than the current seven – which each team must nominate ahead of the season.

kersEnergy Recovery Systems (ERS) – in 2014, a larger proportion of each car’s power will come from ERS which, together with the engine, make up the powertrain or power unit. As well as generating energy under braking, ERS units will also generate power using waste heat from the engine’s turbocharger. Unlike the current KERS – which give drivers an extra 80bhp for six seconds per lap – the 2014 ERS will give drivers around 160bhp for 33 seconds per lap. To compensate for the extra power being generated under braking by ERS, teams will be allowed to use an electronic rear brake control system.

Fuel – to promote fuel efficiency, fuel will be limited to 100kg per race. At the moment fuel is unlimited, but teams typically use around 160kg per race.

Minimum weight – to compensate for the increased weight of the 2014 powertrain, minimum weight has been increased from the current 642kg to 690kg.

dcd1305ju14Exhaust – unlike today where two exhaust tailpipes are used, the 2014 regulations mandate the use of a single tailpipe which must be angled upwards to prevent the exhaust flow being used for aerodynamic effect. Additionally, bodywork is not allowed to be placed behind the tailpipe.

Nose height – for safety reasons the height of noses will be reduced in 2014. The maximum height is currently 550mm, whereas next year it’s 185mm.

Front wing – front wings will be a little narrower next year with the width reduced from 1800mm to 1650mm.

Rear wing – the rear wing will also look a little different in 2014 compared to this year’s models. The lower beam wing is being outlawed and the main flap will be slightly shallower in profile.
