The '''Series 3''' (or '''S3''') and '''Turbo Esprit''' debuted in April 1981. The two models shared a common chassis, and bodywork was based on a common set of moulds.

The S3 received the 2.2 L Type 912 engine. The Turbo Esprit had a wet sump engine with the same power and torque output as its dry sump predecessor. Interior trim was revised which, when combined with changes to the body moulds, resulted in more headroom and an enlarged foot-well.<ref name="LotusTurboEsprit"/> The Turbo Esprit retained the aerodynamic body kit of the Essex cars and featured prominent 'turbo esprit' decals on the nose and sides. The S3 gained the new larger bumpers but kept the simpler sill line and glazed rear hatch of the S2.2 body. Both cars came with {{convert|15|in|mm|0|abbr=on|order=flip}} [[BBS Kraftfahrzeugtechnik|BBS]] alloy wheels. One interesting omission was that the Esprit S3 had no cigarette lighter as standard equipment; ashtrays are tucked away in the door sills.<ref name=TV188232>{{cite magazine | title = 80-talets silverpil | trans-title = A Silver Arrow For the Eighties | ref = TVn18 | language = sv | magazine = [[Teknikens Värld]] | publisher = Specialtidningsförlaget AB | location = Stockholm, Sweden | page = 32 | date = 25 August 1982 | issue = 18 | volume = 34 | first = Dag E | last = Hogsten }}</ref>

Minor changes were made to bodywork and front suspension for the 1985 model year.<ref name="AR87-357">''Automobil Revue 1987'', p. 357</ref>

The final incarnations of the Giugiaro-styled Esprit were announced in April 1986. Higher compression ratios for the engines was indicated by the ''''HC'''' moniker. Power output of the naturally aspirated engine rose to {{convert|172|PS|kW hp|0|abbr=on}} and {{convert|160|lbft|Nm|0|abbr=on}} for the '''Esprit HC''', and to {{convert|218|PS|kW hp|0|abbr=on}} and {{convert|220|lbft|Nm|0|abbr=on|order=flip}} for the '''Turbo Esprit HC''', with more torque available at lower engine speeds.<ref name="lotusespritworld.com/ERoadtests">{{cite web|url=http://www.lotusespritworld.com/ERoadtests/87TurboHC_Fastlane.html|title=When the BOOST BLOWS|access-date=17 December 2007|work=lotusespritworld.com/ERoadtests}}</ref>

For markets with stringent emissions requirements like the United States, Lotus introduced the first fuel-injected Esprits. The '''HCi''' variant added [[Robert Bosch GmbH|Bosch]] [[Jetronic#KE-Jetronic (1985–1993)|KE-Jetronic fuel injection]] and a catalytic converter to the Turbo HC engine. This engine had the same peak power as the carburetted version but at a somewhat higher engine speed. Torque dropped to {{convert|274|Nm|lbft|0|abbr=on}}.<ref name="AR87-357"/>
