Editing Volkswagen Beetle (section)

=== Final models: 1986–2003 ===
Starting in 1986, for the 1987 [[model year]], the sole model available was the single-carburettor version with {{convert|1584|cc|L|1|disp=flip}}. From late 1992 for the 1993 model year, Volkswagen standardised [[catalytic converter]]s, the [[Bosch (company)|Bosch]] [[Digifant engine management system]], a [[lambda probe]] and [[electric ignition]]. This fuel-injection system proved much more straightforward and reliable than previous injection systems used on German-assembled Volkswagens since 1967. Vehicles with these modifications can be identified externally by the reintroduced louvred engine lid, heavier and larger bumper bars, four-stud wheels with twenty ventilation holes and a "1600i" badge on the engine lid. The 1993 model also featured a [[Volkswagen Golf Mk3|third-generation Golf]]-style [[steering wheel]] and front seats, a protection alarm, [[Parking brake|handbrake]] and engine compartment lamps and an optional [[ZF Friedrichshafen|ZF]] [[limited-slip differential]]. The engine received [[hydraulic tappet]]s, a full-flow [[oil filter]], a 6.6:1 [[compression ratio]]—allowing for the use of [[Unleaded gas|unleaded fuel]]—and an electric [[fuel pump]]. A standard version was also released in 1993, featuring painted bumper bars and many minor removals.{{sfn|Glen|2003|p=[https://books.google.com/books?id=hNKSCwAAQBAJ&pg=PT580 580]}}

From 1997, front [[disc brakes]] and an [[immobiliser]] became available, and the De Luxe model featured small traffic indicator side lamps ahead of the top door hinge. The steering wheel's centre boss was restyled to resemble that of the contemporary Golf and Polo. In 1998, Volkswagen removed the small through-flow ventilation slots behind the rear side windows and standardised front disc brakes. Furthermore, Volkswagen included a [[security alarm]] as standard and removed the "1600i" inscription from the engine lid.{{sfn|Glen|2003|p=[https://books.google.com/books?id=hNKSCwAAQBAJ&pg=PT580 580]}}
