When Mercedes-AMG introduced the new SL in October last year, it only showed the "55" and "63" versions powered by a V8. It looks as though an entry-level variant is coming soon as Mercedes-Benz Passion Blog reports a "43" flavor is right around the corner. It’s said to get round tailpipes, which could be shared with the plug-in hybrid model as prototypes of the electrified roadster have been seen with this setup.
While the decision to downsize to such a small engine will raise a few eyebrows among purists, it's worth noting it would not be the first time Mercedes would sell the Sport Leicht with a four-pot. The stunning 190 SL (W121) from the 1950s and 1960s had a 1.9-liter adapted from the 300 SL's straight-six with 120 horsepower on tap.
