Answer 1

The '08 Taurus X is due out in the fall of this year.
It will use the powertrain currantly in the Edge
The following is excerpted from the Ford esource book, regarding the Edge 3.5 engine:
****************
The all-new 3.5L DOHC 24V V-6 engine, available on Edge features an aluminum block and head design and is coupled to a new, electronically controlled 6-speed automatic overdrive transmission.

Major features and benefits: Produces 265 horsepower and 250 lb-ft of torque

Employs variable cam timing on its intake valves (i-VCT)

Dual overhead camshafts with 4 valves per cylinder

All-new design

Engine is PZEV capable

Designed to accept future technologies.

Has excellent fuel efficiency and emissions due to the use of low heat-loss exhaust manifolds and a close-coupled pair of catalysts for faster light off during cold starts

Also features optimized fuel-injector targeting that helps reduce emissions before the catalysts reach their operating temperature

Uses 87-octane fuel unlike the competition which often requires mid-grade to premium fuel
