Mercedes-Benz ML450 and S400 Hybrids
New: Two hybrid powertrains.
Noteworthy: Give Mercedes-Benz credit - it doesn't commit to anything halfway. Although the automaker has long hesitated on hybrids, it now comes to the market with not one but two sophisticated designs. The S400 uses a small motor sandwiched between its 3.5-liter V-6 and seven-speed automatic and is the first production hybrid to use lithium-ion batteries. The ML450 also employs the 3.5-liter V-6 but ties it to the two-mode technology Mercedes codeveloped with General Motors, Chrysler, and BMW. Both hybrids promise impressive gains in fuel economy, with the ML450 improving 6 mpg in the city over an ML350 and the S400 achieving an EPA-estimated 26 mpg on the highway.
