Nuts & Bolts
The bottom line: The 2010 Mercedes-Benz S400 Hybrid is more of a fashion statement than it is an environmental, conservation or performance statement. Equally good fuel economy, with emissions low enough to meet the tough air quality standards of the California Air Resources Board, can be had through the company's advanced diesel offerings, such as the E320 BlueTec sedan.
Complaints: Enough said.
Ride, acceleration and handling: Excellent in all three.
Head-turning quotient: It's an S-Class Mercedes-Benz, the Donald Trump of automobiles. It's hard to ignore.
