With only a single drivetrain to its spec-sheet credit, the 2011 Hyundai Equus is a straightforward luxury sedan with average green credentials.
The V-8, rear-drive Equus earns an EPA rating of 16/24 mpg for the 2011 model year.
Hyundai plans on introducing a larger, higher-output V-8 in 2011, but hasn't announced that 429-hp V-8's fuel economy. The new model will arrive alongside a new eight-speed automatic, so fuel economy may top that of today's Equus.
No hybrid, electric or diesel versions of the Equus are planned for the American market.
