The Mercedes-Benz SL-Class roadster flagship moves into 2016 with relatively minor changes: The entry-level SL550 gets a power increase, and the SL63 AMG can be optioned with a limited Canada Edition package.
SL550 models now boast 449 hp from their 4.7L twin-turbo V8, up from 429; the torque figure of 516 lb-ft remains the same. The SL63's twin-turbo 5.5L V8 generates 577 hp and 664 lb-ft, and the SL65 uses a twin-turbo 6.0L V12 cranking out 621 hp and 737 lb-ft. All engines come with a seven-speed automatic transmission and rear-wheel drive.
Fuel consumption ratings are 14.6/9.6 L/100 km (city/highway) in the SL550; 14.7/9.5 in the SL63; and 16.7/11.2 for the SL65.

The SL63 adds a raft of AMG-specific items that bring upgrades to the brakes, active body control system, instrument cluster and seats. There's also a Nappa leather steering wheel, carbon fibre and brushed aluminum interior trim, and velour floor mats. The Canada Edition package brings unique colour options, staggered wheels, and a variety of other trim treatments.
SL65 models get distronic plus, AMG performance media, magic sky control, active lane keeping and blind spot assist, staggered 19-inch front and 20-inch rear wheels, Nappa leather and Alcantara steering wheel, Nappa leather roof liner, and a Bang & Olufsen surround sound stereo.
