Acceleration Shift Strategy
I have the 5AT in SS mode, but this would apply to 6MT as well. If I'm cruising at 50 mph and want to accelerate to 70 mph, which method is best for fuel economy?
1. Leave the car in top gear, increase throttle and slowly accelerate.
2. Maintain current throttle setting, downshift one or two gears to put the engine in a better powerband and accelerate.
3. Downshift and increase throttle to acheive fastest possible acceleration and reach 70 mph sooner.

Research has shown that applying 2/3 throttle in most gears and getting to desired speed quickly is the most efficient.
I vote for 1 with 2/3 throttle applied.
