The seventh generation of Mercedes Benz's flagship roadster has been unveiled. Everything is from the ground up, having been built on a new multi-material platform made from aluminum, steel, magnesium, and other composites. Unlike previous iterations of the SL, the new SL will be available in AMG trims only, and branded as a "Mercedes-AMG" car.
Measuring 185.2-inches (4705 mm) long and 106.3-inches (2700 mm) between the axles the new SL is 2.9 inches (74 mm) longer and rides on a wheelbase stretched 4.5-inches (115 mm) over the previous SL’s. It’s also 6-inches (154 mm) longer than the old AMG GT Roadster, which the SL sends to an early grave, remedying the previously bizarre situation where Mercedes had two different two-seat V8 convertible sports cars covering similar market turf.
It's performance figures have vastly improved as well. The entry-level SL 55 makes 470 hp and 516 lb-ft, while the punchier SL 63 ups those numbers to 577 hp and 590 lb-ft thanks to more turbo boost, improved airflow, and a software tweak. Even the base car can hit 62 mph in 3.9 seconds, but the SL 63 cuts that down to 3.6 seconds, and the PHEV, expected for release next year, could go even harder if it borrows its hardware from the 831hp AMG GT 63 E, unveiled this September’s Munich show. The SL 55 will top out at 183 mph, leaving the SL 63 to romp ahead to 196 mph. A nine-speed automatic transmission is the only available option, and all models have 4MATIC, Mercedes' all-wheel drive system. Modern five-link front suspension, carbon-ceramic brakes, and rear-wheel steering also come standard on both 55 and 63.
