Described as "the ultimate versions of the Elise and Exige", the Final Edition models gain extra kit, a performance boost and bespoke design elements.
Chief among the revisions for the final production cars is the addition of a new digital gauge cluster with a choice of conventional dials or race-style digital readouts. There is also a new Alcantara/leather steering wheel design and unique seat trim patterns and each car will be supplied with a Final Edition build plaque.
Both the Elise and Exige will be available in "some of the iconic colour schemes" from their past, including Azure Blue, black and Racing Green.
The Elise Sport 240 Final Edition, priced from £45,500, replaces the Sport 220 as the entry point into the Lotus range for the final few months of the model's production. With a 23bhp power boost from its 1.8-litre supercharged four-cylinder taking output to 240bhp, it boasts a power-to-weight ratio of 260bhp per tonne and covers 0-60mph in 4.1sec.
The Sport 240 wears a set of 10-spoke alloy wheels - 0.5kg lighter apiece than those on the 220 - and can be optionally specified with carbonfibre body panels, a polycarbonate rear window and lithium ion battery to take kerb weight from 922kg to 898kg.
The Cup 250 Final Edition, at £50,900, is mechanically unaltered over the standard car but gains an uprated aero package for 66kg of downforce at 100mph, and 155kg at its 154mph top speed. It's equipped as standard with a Bilstein sports suspension system and adjustable anti-roll bars and it can be specified with the same weight-saving measures as the 240 for a minimum weight of 931kg.
There are power increases across the 3.5-litre V6-powered Exige range, too, with the Sport 390 replacing the Sport 350 with 397bhp, and the Sport 410 making way for the 420bhp Sport 420.
A 47bhp power boost for the entry-level Exige, now priced from £64,000, comes courtesy of a recalibrated supercharger and - along with uprated aero - sends the car from standstill to 60mph in 3.7sec and on to 172mph.
