2011 Lincoln MKZ Hybrid EPA-Rated at 41 mpg City/36 mpg Highway; Most Fuel Efficient Luxury Sedan in US

16 June 2010

Lincoln’s 2011 Lincoln MKZ Hybrid (earlier post) now officially carries an EPA-certified 41 mpg rating in city driving and 36 mpg on the highway, making it the officially the most fuel-efficient luxury sedan in the US.

The 2011 Lincoln MKZ Hybrid’s final fuel economy certification was completed this week. It tops its nearest competitor—the 2010 Lexus HS 250h—by 6 mpg. It also trumps the Lexus HS 250h with room for one more passenger and more standard luxury and segment-exclusive safety features, Ford notes.

The 2011 Lincoln MKZ Hybrid uses the company’s second-generation hybrid technology based on the 2.5-liter Atkinson-cycle I-4 engine and hybrid system. The combined gasoline engine and electric motor provide 191 net horsepower (142 kW). The pure electric mode on the Lincoln MKZ Hybrid extends to 47 mph (76 km/h) compared with the Lexus HS 250h battery-only mode, which reaches 25 mph (40 km/h).

It seems that Ford has improved Toyota's HEV platform one more time; 41 mpg and 36 mpg for a large heavy car is even better than CAFE 2016 standards. Imagine what could be done with a light weight very low drag low road resistance car.

The Lincoln MKZ Hybrid is basically a rebadge of the Ford Fusion Hybrid. Nothing new here.

It is impressive that Ford is beating Toyota at their own game, though. Anyone know offhand if Ford is favoring fuel-economy over emissions? Historically, Toyota hybrids have been tuned for very low emissions at the expense of some fuel economy.

Wonder if real-world fuel economy numbers will still be better than the Lexus HS250h as the EPA numbers indicate.

Toyota needs to step up with their hybrid systems.

Yes, it is good to have Ford pushing Toyota to upgrade their HEVs.

Ford's bag of tricks isn't empty yet. The 2.5 Atkinson could be replaced with a 1.6 Ecoboost on the Miller cycle, boosting thermal efficiency even more while cutting weight. A 47 MPH all-electric limit is also well-suited to PHEV.

This car is just the beginning.
