Facelift (2017) A mid-cycle facelift was introduced in 2016 for the 2017 model year. Launched early 2016 in California, the revised SL 400 (renamed SL 450 in the US) featured a 3-litre biturbo V6 mated, for the first time in the SL, to Mercedes' own 9G-Tronic PLUS 9-speed automatic transmission. An SL 500 (US SL 550), with a 4.7 litre biturbo V8 producing , was likewise paired with the 9G-tronic PLUS transmission. The Mercedes-AMG SL 63 () and SL 65 () variants continued with virtually unchanged powertrains, paired with AMG's SPEEDSHIFT MCT 7-speed sports transmission with claimed improved shift times. Cosmetically, every SL received a revised front end, front grille treatment and larger non-functional side 'vents' behind the front wheels. All variants also received adaptive LED front headlights with integrated daytime running lights and turn signals, leaving the below bumper intake area free from lighting. The LED tail lights received single colour red or red and amber lenses instead of the red and white of the pre-facelift models. Front and rear bumper assemblies were redesigned to align more closely with recent models introduced by Mercedes, while selected convenience and driver assistance technologies, introduced earlier on various other Mercedes models, were made optionally available, including revised Active Body Control (ABC), now with the "Curve Tilting" function from the S-Class Coupe. Externally, the SL 63 and SL 65 were distinguishable from the non-AMG variants by embellishments to their bumper assemblies and side sills in gloss black or polished aluminium, respectively. The SL 63 and SL 65 also featured trademark AMG 'twin lamella' front grilles and dual twin tailpipe exhaust trims as well as a carbon fibre composite trunk lid. A slight revision to the folding 'Vario-roof' hardtop operation meant it would continue to deploy at speeds up to once initiated and the luggage compartment partition, required to prevent the hardtop components, when folded, and any luggage compartment contents coming into contact with each other, no longer had to be deployed in a separate manual operation. Interiors continued virtually unchanged for MY2017 with the exception of slightly revised minor switchgear and a redesigned steering wheel. ==Engines and transmissions==
