You can see the advantage of the EcoBoost V-6 compared to a V-8 when looking at the 2010 Mercedes-Benz E-Class. The E-550 Sedan with a 5.5-liter V-8 has EPA estimates of 14 mpg city, 20 mpg highway. Granted, the E-550's engine produces 33 more horsepower, but the number is largely academic given how owners will drive these vehicles.
Which would you rather have day in and day out, 32 horsepower or 20-percent better fuel economy?
When equipped with the boosted V-6, the MKS also gets upfitted with a stiffer suspension and a re-calibrated power steering (it's an electric system, not hydraulic). While the springs are stiffer, this does not mean the ride is stiff, just well controlled and still completely satisfactory for a luxury car. This is not a Lotus Elise, but it's not a Lincoln Town Car either.
When pushed harder than any Lincoln driver will ever push, the MKS takes a set in a corner and easily manages the power from the EcoBoost engine via the standard all-wheel-drive system. New-for-2010 paddle shifters make playing boy racer safer because you can keep your hands on the steering wheel instead of futzing with the floor-mounted shifter as was the only option in 2009. Overall, responsiveness is spot on for a car in this class.
The 2010 Lincoln MKS Sport with EcoBoost is a car luxury sedan prospects should consider because if offers something unique in terms of performance (and economy) that helps differentiate the sedan from other luxury cars.
Pricing for the MKS with EcoBoost technology is $47,760. Let's hope that this represents a value to shoppers (in comparison, an all-wheel-drive 2010 Mercedes-Benz E-550 has a base MSRP of $58,800). This kind of value will help Ford Motor Company rebuild its neglected and currently inconsequential luxury brand.
