Mercedes-Benz
The SL43 makes that power in an unusual way. The turbocharger strapped to the 2.0-liter engine includes an electric motor along with the usual exhaust-gas plumbing. The motor—a 1.6-inch-wide unit slotted onto the shaft between the turbine and compressor wheel—can spin the compressor wheel before the exhaust gases do.
The visual changes for the SL43 are minimal, with simpler styling for the front and rear bumpers and round tailpipes instead of the squared-off outlets on the eight-cylinder SLs. The standard wheels measure 19 inches across, but the SL43 can also be ordered with 20- or 21-inch wheels. The opulent cabin is unchanged for the entry-level model, and power-adjustable heated and cooled Nappa leather seats come standard.
